5549f7a1f35db7552600000d | yesno | Can a given genotype exhibit opposite fitness effects (beneficial and detrimental) within the same environment? | [
"A given genotype can be either beneficial or detrimental, even deleterious, depending on the environment in which an organism lives. This is known as antagonistic pleiotropy. Antagonistic pleiotropy can operate even within the same environment. For example, in Escherichia coli, certain mutations can exhibit beneficial, deleterious or neutral fitness effects at different growth rates. Also, antagonistic pleiotropy is involved in the evolution of ageing, since a certain genotype may affect late- and early-life fitness in opposite directions."
] | [
"yes"

"Mutations beneficial in one environment may cause costs in different environments, resulting in antagonistic pleiotropy. Here, we describe a novel form of antagonistic pleiotropy that operates even within the same environment, where benefits and deleterious effects exhibit themselves at different growth rates.",
"The hfq mutations were beneficial, deleterious or neutral at an intermediate growth rate (0.5 h(-1)) and one changed from beneficial to deleterious within a 36 min difference in doubling time.",
"Two genetic models exist to explain the evolution of ageing - mutation accumulation (MA) and antagonistic pleiotropy (AP).",
"Under AP, late-acting deleterious mutations accumulate because they confer beneficial effects early in life.",
"Many marker loci responded in opposite directions to selection for late- and early-life fitness, indicating negative genetic correlations or trade-offs between those traits. Indirect evidence suggested that some negative genetic correlations were due to antagonistic pleiotropy.",

5175b97a8ed59a060a00002f | yesno | Is alternative splicing of apoptotic genes playing a role in the response to DNA or mitochondrial damage? | [
"Yes, alternative splicing seem to play a key role in the response to DNA or mitocondrial damage as suggested by the number of apoptotic genes that are alternatively spliced, with often antagonistic roles of the isoforms generated."
] | [
"yes"
] | [
"Apoptosis promoted by UV in cells lacking p53 is prevented when the change in AS of the apoptotic gene bcl-x is reverted, confirming the relevance of this mechanism.",
"We demonstrate that E2F1 requires SC35 to switch the alternative splicing profile of various apoptotic genes such as c-flip, caspases-8 and -9 and Bcl-x, towards the expression of pro-apoptotic splice variants. Finally, we provide evidence that E2F1 upregulates SC35 in response to DNA-damaging agents and show that SC35 is required for apoptosis in response to these drugs.",
"This analysis revealed that DNA damage resulted in changes in splicing activity that modified the splicing pattern of Fas, a key pro-apoptotic, p53-inducible death receptor.",
"Bortezomib induces mitochondrial damage in native cells and also activates the UPR by splicing of Xbp-1 and induction of CHOP, which is significantly reduced by silencing of MUC4.",
"The tumour-suppressor protein p53 is an important activator of apoptosis. Although p53-deficient cancer cells are less responsive to chemotherapy, their resistance is not complete, which suggests that other apoptotic pathways may exist. A p53-related gene, p73, which encodes several proteins as a result of alternative splicing, can also induce apoptosis.",
"Induction of apoptosis was significantly reduced in P388/SPR cells, as indicated by minimal DNA fragmentation. Analysis of oncogenes regulating apoptotic cell death revealed a marked decrease of bcl-2 in combination with a moderate reduction of bax protein, but a striking overexpression of the long form of the bcl-X protein."

"A role for c-Abl in cell senescence and spontaneous immortalization",
"Here, we report an important role for c-Abl in replicative senescence and immortalization by regulating the expression of two tumor suppressors that induce cellular senescence, p53 and p16(INK4a).",

"oncogene-induced senescence, Myc style",
"We review and discuss here evidence for Myc-induced senescence - which is detectable to a limited degree as a cell-autonomous, direct response to Myc action, but occurs predominantly in a non-cell-autonomous fashion via crosstalk of the oncogene-driven cell population with non-neoplastic bystanders, namely cells of the host immune system, prompting them to release pro-senescent cytokines that strike back onto adjacent proliferating tumor cells.",

"MYC inactivation was associated with prototypical markers of senescence",
"only after lymphomas were repaired for p53 expression did MYC inactivation induce robust senescence and sustained tumor regression.",
"Replicative senescence due to telomere shortening can, for example, be induced by a dominant negative version of telomerase, premature senescence by the overexpression of oncogenic ras, or p16.",
"knockdown of HDAC2 induced cellular senescence.",
"MYC overexpression is thought to initiate tumorigenesis by inducing cellular proliferation and growth and to be restrained from causing tumorigenesis by inducing cell cycle arrest, cellular senescence, and/or apoptosis.",

"Mitogen-activated protein kinase p38 defines the common senescence-signalling pathway",
"These results indicate that p38 comprises the senescence-executing pathway in response to diverse stimuli.",
"this p38-activating condition appears to be defined quantitatively as a sum of continuous and low-level stresses, and remains even after the initial stimuli are withdrawn, which may explain the well-known irreversible nature of cellular senescence.

"Expression of caveolin-1 induces premature cellular senescence in primary cultures of murine fibroblasts",
"Here, we demonstrate that mouse embryonic fibroblasts transgenically overexpressing caveolin-1 show: 1) a reduced proliferative lifespan; 2) senescence-like cell morphology; and 3) a senescence-associated increase in beta-galactosidase activity. These results indicate for the first time that the expression of caveolin-1 in vivo is sufficient to promote and maintain the senescent phenotype.",
"Interestingly, premature senescence induced by hydrogen peroxide is greatly reduced in NIH 3T3 cells harboring antisense caveolin-1. Importantly, induction of premature senescence is recovered when caveolin-1 levels are restored.",
"these results clearly indicate a central role for caveolin-1 in promoting cellular senescence",
"Oncogenic activation of the mitogen-activated protein (MAP) kinase cascade in murine fibroblasts initiates a senescence-like cell cycle arrest that depends on the ARF/p53 tumor suppressor pathway.",
"In contrast, coexpression of oncogenic ras or activated mek1 with p53 enhanced both p53 levels and activity relative to that observed for p53 alone and produced an irreversible cell cycle arrest that displayed features of cellular senescence.",
"our results indicate that oncogenic activation of the MAP kinase pathway in murine fibroblasts converts p53 into a senescence inducer through both quantitative and qualitative mechanisms.",
"Myc-evoked apoptosis serves as a signal for macrophage attraction and activation, followed by the secretion of TGF-β as a cytokine that is capable of terminally arresting Myc-driven lymphoma cells without causing further DNA damage and without launching a senescence-associated, pro-inflammatory, and, therefore, potentially detrimental cytokine response in the target population.",

"Modulation of the immune system by targeting coinhibitory and costimulatory receptors has become a promising new approach of immunotherapy for cancer. OBJECTIVE: CT-011 is a humanized IgG1 monoclonal antibody that modulates the immune response through interaction with PD-1, a protein belonging to the B7 receptor family present on lymphocytes. The objectives of this phase I study were to assess the dose-limiting toxicities, to determine the maximum tolerated dose, and to study the pharmacokinetics of CT-011 administered once to patients with advanced hematologic malignancies. We have developed a cancer vaccine in which autologous tumor is fused with dendritic cells resulting in the presentation of tumor antigens in the context of DC-mediated costimulation. The median t1/2 of CT-011 ranged from 217 to 410 hours. The PD1/PDL1 pathway is an important element contributing to tumor-mediated immune suppression. The recent approval of the CTLA-4-blocking antibody ipilimumab for the treatment of melanoma was a watershed event, opening up a new era in the field of immunotherapy. T-cell expression of programmed death receptor-1 down-regulates the immune response against malignancy by interacting with cognate ligands ( eg, PD-L1 ) on tumor cells; however, little is known regarding PD-1 and natural killer ( NK ) cells.

"miRNA 29 is involved in post-ischemic myocardial remodeling in particular in the peri-infarctual zone. miRNA 29 produces apoptosis and enhances fibrotic response."
] | [
"yes"
] | [
"Myocardial ischaemia/reperfusion (I/R)-induced remodelling generally includes cell death (necrosis and apoptosis), myocyte hypertrophy, angiogenesis, cardiac fibrosis, and myocardial dysfunction. I",
"In addition, miR-21, -24, -133, -210, -494, and -499 appear to protect myocytes against I/R-induced apoptosis, whereas miR-1, -29, -199a, and -320 promote apoptosis",
"Myocardial fibrosis can be regulated by the miR-29 family",
"Studies using various in vivo, ex vivo, and in vitro models have suggested the possible involvement of miR-1, miR-21, miR-29, miR-92a, miR-133, miR-199a, and miR-320 in ischemia-reperfusion injury and/or remodeling after myocardial infarction.",
"Among the MI-regulated miRNAs are members of the miR-29 family, which are down-regulated in the region of the heart adjacent to the infarct. The miR-29 family targets a cadre of mRNAs that encode proteins involved in fibrosis, including multiple collagens, fibrillins, and elastin. Thus, down-regulation of miR-29 would be predicted to derepress the expression of these mRNAs and enhance the fibrotic response. Indeed, down-regulation of miR-29 with anti-miRs in vitro and in vivo induces the expression of collagens, whereas over-expression of miR-29 in fibroblasts reduces collagen expression. We conclude that miR-29 acts as a regulator of cardiac fibrosis and represents a potential therapeutic target for tissue fibrosis in general."

"In eukaryotic cells, XRN1 is often found in particles known as processing bodies (P bodies) together with other proteins involved in the 5' → 3' degradation pathway, such as DCP2 and the helicase DHH1 (Me31B). In yeast and human tissue culture cells, Xrn1 has been shown to be a component of P-bodies (processing bodies), dynamic cytoplasmic granules where RNA degradation can take place. Many P-body components including LSM1, GW182, DDX3, DDX6 and XRN1, but not others like DCP1a and EDC4 are recruited to the viral replication sites, as evidenced by their colocalization at perinuclear region with viral NS3.",
"In eukaryotic cells, degradation of bulk mRNA in the 5' to 3' direction requires the consecutive action of the decapping complex (consisting of DCP1 and DCP2) and the 5' to 3' exonuclease XRN1. These enzymes are found in discrete cytoplasmic foci known as P-bodies.",
"We show that the RNA-binding protein GW182 and the DCP1:DCP2 decapping complex are required for miRNA-mediated gene silencing, uncovering a crucial role for P-body components in the miRNA pathway. An alternative pathway of mRNA degradation occurs at processing bodies, cytoplasmic foci that contain decapping enzymes, the 5'-3' exonuclease Xrn1 and the Lsm1-7 heptamer. Our results show that mammalian cells, similar to yeast, require the 5'-3' Xrn1 pathway to degrade ARE-mRNAs. Recent evidence suggests that the processing bodies may constitute specialized cellular compartments of mRNA turnover, which suggests that mRNA and protein localization may be integral to mRNA decay."

554403395beec11c10000001 | summary | Which is the primary distinction between the Reverse Warburg effect and the conventional Warburg effect? | [
"The conventional \"Warburg effect\" reffers to the metabolic shift of cancer cells towards aerobic glycolysis, due to mitochondrial dysfunction. The \"reverse Warburg effect\" or \"parasitic\" energy-transfer, is a model of \"two-compartment tumor metabolism\". In this model, cancer cells secrete hydrogen peroxide (H2O2), initiating oxidative stress and aerobic glycolysis in the tumor stroma. The cancer-associated fibroblasts of the stroma are glycolytic and lack detectable mitochondria. These glycolytic stromal cells produce mitochondrial fuels (L-lactate, ketone bodies and chemical building blocks, such as amino acids -glutamine-, and nucleotides) that are then transferred to oxidative epithelial cancer cells. Lactate and ketones drive cancer cell oxidative mitochondrial metabolism (OXPHOS), and building blocks sustain the anabolic needs of rapidly proliferating cancer cells. Therefore, according to the \"reverse Warburg effect\", stromal catabolism fuels anabolic tumor growth via energy transfer. Thus, in \"reverse Warburg effect\" the cancer-associated fibroblasts of the stroma undergo aerobic glycolysis, rather than epithelial cancer cells themselves, as proposed by the conventional \"Warburg effect\"."
] | [] | [
"The metabolic energy transduction pathways are strongly affected in cancers. Mitochondrial dysfunction in cancer cells (Warburg effect) or in fibroblasts associated with cancer cells (reverse Warburg effect) results in decreased or increased power of the generated electromagnetic field, respectively",
"cigarette smoke induces catabolism in the local microenvironment, directly fueling oxidative mitochondrial metabolism (OXPHOS) in neighboring epithelial cancer cells, actively promoting anabolic tumor growth.",
"our current findings are consistent with the idea that cigarette smoke induces the \"reverse Warburg effect,\" thereby fueling \"two-compartment tumor metabolism\" and oxidative mitochondrial metabolism in epithelial cancer cells.",
"We have recently proposed a new two-compartment model for understanding the Warburg effect in tumor metabolism. In this model, glycolytic stromal cells produce mitochondrial fuels (L-lactate and ketone bodies) that are then transferred to oxidative epithelial cancer cells, driving OXPHOS and mitochondrial metabolism. Thus, stromal catabolism fuels anabolic tumor growth via energy transfer. We have termed this new cancer paradigm the \"reverse Warburg effect,\" because stromal cells undergo aerobic glycolysis, rather than tumor cells.",
"Consistent with the \"reverse Warburg effect,\" our results indicate that metastatic breast cancer cells amplify oxidative mitochondrial metabolism (OXPHOS) and that adjacent stromal cells are glycolytic and lack detectable mitochondria.",
"\"glycolytic\" cancer cells were rarely observed, indicating that the conventional \"Warburg effect\" does not frequently occur in cancer-positive lymph node metastases.",
"We have recently proposed a new model of cancer metabolism to explain the role of aerobic glycolysis and L-lactate production in fueling tumor growth and metastasis. In this model, cancer cells secrete hydrogen peroxide (H2O2), initiating oxidative stress and aerobic glycolysis in the tumor stroma. This, in turn, drives L-lactate secretion from cancer-associated fibroblasts. Secreted L-lactate then fuels oxidative mitochondrial metabolism (OXPHOS) in epithelial cancer cells, by acting as a paracrine onco-metabolite. We have previously termed this type of two-compartment tumor metabolism the \"Reverse Warburg Effect,\" as aerobic glycolysis takes place in stromal fibroblasts, rather than epithelial cancer cells.",
"the \"Reverse Warburg Effect\" or \"parasitic\" energy-transfer",
"We have previously demonstrated that enhanced aerobic glycolysis and/or autophagy in the tumor stroma supports epithelial cancer cell growth and aggressive behavior, via the secretion of high-energy metabolites. These nutrients include lactate and ketones, as well as chemical building blocks, such as amino acids (glutamine) and nucleotides. Lactate and ketones serve as fuel for cancer cell oxidative metabolism, and building blocks sustain the anabolic needs of rapidly proliferating cancer cells. We have termed these novel concepts the \"Reverse Warburg Effect,\" and the \"Autophagic Tumor Stroma Model of Cancer Metabolism.",
"Previously, we proposed that cancer cells behave as metabolic parasites, as they use targeted oxidative stress as a \"weapon\" to extract recycled nutrients from adjacent stromal cells. Oxidative stress in cancer-associated fibroblasts triggers autophagy and mitophagy, resulting in compartmentalized cellular catabolism, loss of mitochondrial function, and the onset of aerobic glycolysis, in the tumor stroma. As such, cancer-associated fibroblasts produce high-energy nutrients (such as lactate and ketones) that fuel mitochondrial biogenesis, and oxidative metabolism in cancer cells. We have termed this new energy-transfer mechanism the \"reverse Warburg effect.\"",
"Recently, we proposed a new mechanism for understanding the Warburg effect in cancer metabolism. In this new paradigm, cancer-associated fibroblasts undergo aerobic glycolysis, and extrude lactate to \"feed\" adjacent cancer cells, which then drives mitochondrial biogenesis and oxidative mitochondrial metabolism in cancer cells. Thus, there is vectorial transport of energy-rich substrates from the fibroblastic tumor stroma to anabolic cancer cells.",
" the \"reverse Warburg effect,\" which states that cancer-associated fibroblasts undergo aerobic glycolysis, thereby producing lactate, which is utilized as a metabolic substrate by adjacent cancer cells. In this model, \"energy transfer\" or \"metabolic-coupling\" between the tumor stroma and epithelial cancer cells \"fuels\" tumor growth and metastasis, via oxidative mitochondrial metabolism in anabolic cancer cells.",
"the Warburg effect in cancer cells may be due to culturing cancer cells by themselves, out of their normal stromal context or tumor microenvironment. In fact, when cancer cells are co-cultured with fibroblasts, then cancer cells increase their mitochondrial mass, while fibroblasts lose their mitochondria.",
" stromal catabolism, via autophagy and mitophagy, fuels the anabolic growth of tumor cells, promoting tumor progression and metastasis. We have previously termed this new paradigm \"The Autophagic Tumor Stroma Model of Cancer Metabolism\", or the \"Reverse Warburg Effect\".",
"Our findings are consistent with the recently proposed \"Reverse Warburg Effect\" and the \"Autophagic Tumor Stroma Model of Cancer Metabolism.\" In these two complementary models, cancer cells induce oxidative stress in adjacent stromal cells, which then forces these stromal fibroblasts to undergo autophagy/mitophagy and aerobic glycolysis. This, in turn, produces recycled nutrients (lactate, ketones and glutamine) to feed anabolic cancer cells, which are undergoing oxidative mitochondrial metabolism.",
"cancer-associated fibroblasts undergo aerobic glycolysis and the resulting energy-rich metabolites are then transferred to epithelial cancer cells, where they enter the TCA cycle, resulting in high ATP production via oxidative phosphorylation. We have termed this new paradigm \"The Reverse Warburg Effect.\"",
"Previously, we proposed a new model for understanding the Warburg effect in tumorigenesis and metastasis. In this model, the stromal fibroblasts would undergo aerobic glycolysis (a.k.a., the Warburg effect)--producing and secreting increased pyruvate/lactate that could then be used by adjacent epithelial cancer cells as \"fuel\" for the mitochondrial TCA cycle, oxidative phosphorylation, and ATP production.",
"In this alternative model of tumorigenesis, the epithelial cancer cells instruct the normal stroma to transform into a wound-healing stroma, providing the necessary energy-rich micro-environment for facilitating tumor growth and angiogenesis. In essence, the fibroblastic tumor stroma would directly feed the epithelial cancer cells, in a type of host-parasite relationship. We have termed this new idea the \"Reverse Warburg Effect.\" In this scenario, the epithelial tumor cells \"corrupt\" the normal stroma, turning it into a factory for the production of energy-rich metabolites.",
"Warburg's original observation that tumors show a metabolic shift towards aerobic glycolysis.",
"The reverse Warburg effect: aerobic glycolysis in cancer associated fibroblasts and the tumor stroma.",
"We have termed this new cancer paradigm the \"reverse Warburg effect,\" because stromal cells undergo aerobic glycolysis, rather than tumor cells.",
"Thus, we conclude that ketones and lactate fuel tumor growth and metastasis, providing functional evidence to support the \"Reverse Warburg Effect\".",
"We have termed this new cancer paradigm the \"reverse Warburg effect,\" because stromal cells undergo aerobic glycolysis, rather than tumor cells"

] | [
"yes"
] | [
"Vortioxetine is an orally administered small molecule developed by Lundbeck A/S for the once-daily treatment of major depressive disorder (MDD) and generalized anxiety disorder (GAD). Vortioxetine received its first global approval for MDD in the USA in September 2013 and regulatory approval for its use in this indication in the EU (where it has received a positive opinion) and Canada is awaited. ",
"This article summarizes the milestones in the development of vortioxetine leading to this first approval for MDD.",
"Vortioxetine was efficacious and well tolerated in the treatment of patients with major depressive disorder.",
"On the primary efficacy endpoint, both vortioxetine doses were statistically significantly superior to placebo, with a mean difference to placebo (n=158) of -5.5 (vortioxetine 15 mg, P<0.0001, n=149) and -7.1 MADRS points (vortioxetine 20 mg, P<0.0001, n=151).",
"The change in the severity of depressive and anxiety symptoms was maintained throughout the study as reflected by a 24-item Hamilton Depression Scale total score of 8.2 at week 52 (from 17.6 at open-label baseline) in the observed case data set.",
"Vortioxetine is a multi-modal antidepressant that functions as a human 5-HT3A and 5-HT7 receptor antagonist, 5-HT1B receptor partial agonist, 5-HT1A receptor agonist, and inhibitor of the serotonin transporter. ",
"Approval for the treatment of MDD was based on a clinical development programme that included six positive 6-8 week studies, including one study in elderly people, and one positive maintenance study in adults.",
"Vortioxetine represents another option for the treatment of MDD. ",
"The multimodal compounds vortioxetine and vilazodone are examples of this approach with diverse mechanisms, and their different clinical effects will provide valuable insights into serotonergic modulation of glutamate transmission for the potential treatment of depression and associated cognitive dysfunction.",
"Two new antidepressant drugs, vilazodone (marketed in the USA) and vortioxetine (in development) incorporate partial 5-HT1A-R agonist properties with SERT blockade.",
"Novel drugs in development include those that combine multiple simultaneous pharmacologic mechanisms in addition to SERT inhibition within the same molecule, such as vilazodone (combining 5HT1A partial agonism with SERT inhibition), triple reuptake inhibitors (combining norepinephrine and dopamine reuptake inhibition with SERT inhibition), and vortioxetine, a multimodal antidepressant combining actions at the G protein receptor mode (5HT1A and 5HT1B partial agonism and 5HT7 antagonism), at the ion channel mode (5HT3 antagonism) as well as the neurotransmitter transporter mode (SERT inhibition). ",
"In this study of adults with MDD treated for 8 weeks with vortioxetine 2.5 mg or 5 mg per day, reductions in depression symptoms were not statistically significant compared with placebo. ",
"However, on the basis of these findings, vortioxetine (2.5, 5, 10 mg/day) demonstrated a favourable safety and tolerability profile and maintained effectiveness over 12 months of treatment. ",
"In this study of adults with MDD, 5 mg vortioxetine did not differ significantly from placebo in reducing depression symptoms after 6 wk of treatment.",
"After 8 weeks of treatment with Lu AA21004 10 mg, there was a significant reduction in HDRS-24 total score compared with placebo in adults with MDD.",
"In conclusion, Lu AA21004 was efficacious and well tolerated in the treatment of elderly patients with recurrent major depressive disorder.",
"Thus, Lu AA21004 was effective in preventing relapse of MDD and was well tolerated as maintenance treatment.",
" Findings on secondary outcome measures, using MMRM instead of LOCF, were supportive of likely efficacy for Lu AA21004 5mg and 10mg and duloxetine. ",
"In this study, treatment with 5 mg and 10 mg Lu AA21004 for 6 wk was efficacious and well tolerated in patients with MDD.",
"Results from phase II clinical trials have reported improvement in depression and anxiety symptoms after 6 weeks of treatment. "

51753a948ed59a060a000029 | summary | What is the role of AMPK in diabetic cardiomyopathy? | [
"AMPK activation protects cardiac structure and function by increasing cardiac autophagy in the diabetic heart. Decreased AMPK activity and the subsequent reduction in cardiac autophagy are central to the development of diabetic cardiomyopathy. In fact, dissociation of Bcl-2 from Beclin1 may be an important mechanism for preventing diabetic cardiomyopathy via AMPK activation that restores autophagy and protects against cardiac apoptosis. In addition, genetic inhibition of AMPK in cardiomyocytes attenuates cardiac autophagy, exacerbates cardiac dysfunction and increases mortality in diabetic mice. The modulation of AT-1R/AMPK-MAPK pathway might play crucial roles for the pathogenesis of diabetic cardiomyopathy and it could become an important therapeutic target to ameliorate the diabetic cardiomyopathy. Stimulation of AMPK by metformin or trimetazidine administration may represent a novel approach to treat diabetic cardiomyopathy."
] | [] | [
"We recently reported that diabetes depresses AMP-activated protein kinase (AMPK) activity, inhibits MAPK8/JNK1-BCL2 signaling",
"Activation of AMPK directly phosphorylates MAPK8, which mediates BCL2 phosphorylation and subsequent BECN1-BCL2 dissociation, leading to restoration of cardiac autophagy, protection against cardiac apoptosis, and ultimately improvement in cardiac structure and function.",
"studies were shown that p38 MAPK stimulates glucose uptake through the AMPK activation.",
"Taken together, it is suggested that the modulation of AT-1R/AMPK-MAPK pathway might play crucial roles for the pathogenesis of diabetic cardiomyopathy and it could become an important therapeutic target to ameliorate the diabetic cardiomyopathy.",
"We conclude that AMPK activation protects cardiac structure and function by increasing cardiac autophagy in the diabetic heart.",
"Genetic inhibition of AMPK in cardiomyocytes attenuates cardiac autophagy, exacerbates cardiac dysfunction and increases mortality in diabetic mice.",
"Oxidative stress and lipid deposition were markedly increased in the myocardium, concomitant with inactivation of AMPK and increased expression of peroxisome proliferator-activated receptor coactivator-1 alpha (PGC-1 alpha).",
"Trimetazidine also caused AMPK activation and reduced PGC-1 alpha expression in the hearts of db/db mice.",
"The data suggest that trimetazidine significantly improves cardiac function in db/db mice by attenuating lipotoxicity and improving the oxidation status of the heart. Activation of AMPK and decreased expression of PGC-1 alpha were involved in this process.",
"Our findings highlight a role of PP2C and AMPK in the derangements of cardiac lipid metabolism in obesity and provide new insights as to the mechanisms of the liporegulatory disorder leading to lipotoxic cardiomyopathy.",
"We conclude that dissociation of BCL2 from BECN1 through activation of MAPK8-BCL2 signaling may be an important mechanism by which AMPK activation restores autophagy, protects against cardiac apoptosis, and prevents diabetic cardiomyopathy.",
"Both the AMPK activator resveratrol and the antioxidant N-acetylcysteine mimicked the UCF-101-induced beneficial effect in STZ-induced diabetic cardiomyocytes.",
"UCF-101 protects against STZ-induced cardiomyocyte contractile dysfunction, possibly via an AMPK-associated mechanism."

"The role of various p73 isoforms in tumorigenesis has been controversial. However, as we have recently shown, the generation of TAp73-deficient (TAp73(-/-)) mice reveals that TAp73 isoforms exert tumor-suppressive functions, indicating an emerging role for Trp-73 in the maintenance of genomic stability.

"Indeed, tazarotene modulates the expression of the p73 gene in immortalized keratinocyte cell lines by inducing the pro-apoptotic and anti-proliferative TAp73 isoforms and by repressing the anti-apoptotic and pro-proliferative DeltaNp73 isoforms.",

56a8b1a5a17756b72f000004 | summary | What is the mechanism of DNA replication termination in vertebrates? | [
"Eukaryotic DNA replication terminates when replisomes from adjacent replication origins converge. Termination involves local completion of DNA synthesis, decatenation of daughter molecules and replisome disassembly. DNA synthesis does not slow detectably as forks approach each other, and leading strands pass each other unhindered before undergoing ligation to downstream lagging strands. Dissociation of the replicative CMG helicase (comprising CDC45, MCM2-7 and GINS) occurs only after the final ligation step, and is not required for completion of DNA synthesis, strongly suggesting that converging CMGs pass one another and dissociate from double-stranded DNA. This termination mechanism allows rapid completion of DNA synthesis while avoiding premature replisome disassembly."

"Alemtuzumab offers induction strategy for very active relapsing MS patients who have failed conventional therapy, and possibly selected treatment-naive patients.",
"Differential reconstitution of T cell subsets following immunodepleting treatment with alemtuzumab (anti-CD52 monoclonal antibody) in patients with relapsing-remitting multiple sclerosis.",
"Alemtuzumab (anti-CD52 mAb) provides long-lasting disease activity suppression in relapsing-remitting multiple sclerosis (RRMS).",
"Alemtuzumab, an anti-CD52 monoclonal antibody, increased the risk of thyroid dysfunction in CAMMS223, a phase 2 trial in relapsing-remitting multiple sclerosis.",
"Since then, one phase II and two phase III trials have shown that alemtuzumab reduces the relapse rate, compared with the active comparator interferon beta-1a (IFNβ-1a), in treatment-naïve and treatment-experienced MS up to 10 years from disease onset. Furthermore, in two of these trials, alemtuzumab reduced the risk of accumulating disability compared with IFNβ-1a; indeed alemtuzumab treatment led to an improvement in disability and reduction in cerebral atrophy.",
"Alemtuzumab is a humanized monoclonal antibody specific for the CD52 protein present at high levels on the surface of B and T lymphocytes. In clinical trials, alemtuzumab has shown a clinical benefit superior to that of interferon-β in relapsing-remitting multiple sclerosis patients.",
"These results potentially help explain the level of immunocompetence observed in alemtuzumab-treated MS patients.",
"Alemtuzumab was first used in multiple sclerosis in 1991. It is a monoclonal antibody which is directed against CD52, a protein of unknown function on lymphocytes. ",
"Against an active comparator and the current first-line therapy for relapsing-remitting multiple sclerosis (interferon-beta), alemtuzumab showed a significant reduction in annualized relapse rate as well as a significant reduction in the accumulation of disability. ",
"Alemtuzumab (previously known as Campath(®)) is a humanized monoclonal antibody directed against the CD52 antigen on mature lymphocytes that results in lymphopenia and subsequent modification of the immune repertoire. ",
"Compared to interferon beta-1a, alemtuzumab reduced the relapse rate by 49%-74% (P < 0.0001), and in two studies it reduced the risk of sustained disability accumulation by 42%-71% (P < 0.01). In one study (Comparison of Alemtuzumab and Rebif Efficacy in Multiple Sclerosis; CARE-MS1), there was no significant difference compared to interferon, perhaps reflecting the surprisingly low frequency of disability events in the comparator group.",
"Alemtuzumab has been submitted for licensing in relapsing-remitting multiple sclerosis in the United States and Europe.",
"Alemtuzumab was associated with a greater chance of improved contrast sensitivity in patients with RRMS and may delay the worsening of visual function. ",
"The anti-CD52 monoclonal antibody alemtuzumab reduced disease activity in a phase 2 trial of previously untreated patients with relapsing-remitting multiple sclerosis. ",
"Alemtuzumab's consistent safety profile and benefit in terms of reductions of relapse support its use for patients with previously untreated relapsing-remitting multiple sclerosis; however, benefit in terms of disability endpoints noted in previous trials was not observed here. ",
"Alemtuzumab, formally known as Campath-1H, is a humanized monoclonal antibody directed against CD52, a protein on the surface of lymphocytes and monocytes with unknown function. A single dose of alemtuzumab leads to a rapid, profound and prolonged lymphopenia. A Phase II trial has shown that alemtuzumab reduces the risk of relapse and accumulation of disability by over 70% compared with interferon beta in patients with early relapsing-remitting multiple sclerosis (MS).",
"Alemtuzumab, targeting CD52 expressed on T-cells, B-cells, monocytes and macrophages, has also shown to be effective in early RRMS and phase III trials are currently ongoing. ",

"Alemtuzumab (CD52-specific humanized monoclonal antibody) was found to be an effective therapy for treatment-naive patients with relapsing-remitting multiple sclerosis. ",
"Alemtuzumab effectively reduced relapse rates and improved clinical scores in patients with active relapsing-remitting multiple sclerosis not controlled by interferon therapy.",
"Alemtuzumab is an anti-CD52 monoclonal antibody with remarkable efficacy in relapsing multiple sclerosis (MS). ",
"The anti-CD52 monoclonal antibody alemtuzumab reduces disease activity in previously untreated patients with relapsing-remitting multiple sclerosis. ",
"For patients with first-line treatment-refractory relapsing-remitting multiple sclerosis, alemtuzumab could be used to reduce relapse rates and sustained accumulation of disability. ",
"Campath-1H causes the immune response to change from the Th1 phenotype, suppressing multiple sclerosis disease activity, but permitting the generation of antibody-mediated thyroid autoimmunity.",
"Campath-1H is a humanized monoclonal antibody directed at CD52 expressed on lymphocytes and other cells of the immune system. It has been tested extensively in lymphoid malignancies, autoimmune diseases including rheumatoid arthritis, multiple sclerosis, and organ transplantation.",
"Campath 1-H (Alemtuzumab) is a humanised monoclonal antibody which targets the CD52 antigen, a low molecular weight glycoprotein present on the surface of most lymphocyte lineages, causing complement mediated lysis and rapid and prolonged T lymphocyte depletion. Following encouraging initial data from other centres we report our open label experience of using Campath 1-H as a treatment in aggressive relapsing multiple sclerosis in a consecutive series of 39 highly selected patients treated across three regional centres and followed for a mean of 1.89 years.",
"Alemtuzumab, a humanized monoclonal antibody that targets CD52 on lymphocytes and monocytes, may be an effective treatment for early multiple sclerosis. ",
"In patients with early, relapsing-remitting multiple sclerosis, alemtuzumab was more effective than interferon beta-1a but was associated with autoimmunity, most seriously manifesting as immune thrombocytopenic purpura.",
"Alemtuzumab, a monoclonal antibody targeting CD52, is a highly promising agent currently being studied in two phase III clinical trials. In this review, data from the recently published phase II clinical trial in the treatment of early relapsing remitting MS is summarized and analyzed in light of the development of alemtuzumab for MS and its potential role in treating this disease is discussed.",
"Alemtuzumab is a humanized monoclonal antibody against CD52, an antigen found on the surface of normal and malignant lymphocytes. It is approved for the treatment of B-cell chronic lymphocytic leukaemia and is undergoing Phase III clinical trials for the treatment of multiple sclerosis. ",
"To assess the effect of systemic lymphocyte depletion on disease activity, seven patients with MS received a 10-day intravenous course of the humanised monoclonal antibody CAMPATH-1H (anti-CDw52).",
"The effect of CAMPATH-1H on disease activity provides direct, but preliminary, evidence that disease activity in MS depends on the availability of circulating lymphocytes and can be prevented by lymphocyte depletion.",
"The elective treatment of patients with multiple sclerosis, using a humanized anti-leukocyte (CD52) monoclonal antibody (Campath-1H), has illuminated mechanisms that underlie the clinical course of the disease. ",
"Alemtuzumab is currently under review to treat relapsing multiple sclerosis (MS) in the United States, based on positive Phase II and Phase III trials in both treatment-naïve and treated relapsing MS patients. ",
"Alemtuzumab has recently been approved by the European authorities for active relapsing MS, in essence as a first-line agent.",

"New hypothesis-guided targets (e.g., medial forebrain bundle, habenula) are about to be assessed in clinical trials. ",
"Deep brain stimulation (DBS) to the nucleus accumbens (NAcc-DBS) has antidepressant effects in patients suffering from treatment-resistant depression (TRD). ",
"The ventral striatum, including the head of the caudate nucleus and the nucleus accumbens, is a putative target for deep brain stimulation (DBS) in the treatment of obsessive-compulsive disorder (OCD) and major depression (MD). ",
"High frequency stimulation was successfully applied in several small samples of patients with treatment-resistant depression when the stimulation focused on different areas, e.g., nucleus accumbens, the lateral habenula or cortical areas.",
"We recorded electrophysiological activity directly from the nucleus accumbens of five patients undergoing deep brain stimulation for treatment of refractory major depression. ",
"Functional inhibition of the lateral habenula via deep brain stimulation (DBS) has antidepressive properties.",
"Because a prominent clinical feature of depression is anhedonia--the inability to experience pleasure from previously pleasurable activities--and because there is clear evidence of dysfunctions of the reward system in depression, DBS to the nucleus accumbens might offer a new possibility to target depressive symptomatology in otherwise treatment-resistant depression.",
"These preliminary findings suggest that DBS to the nucleus accumbens might be a hypothesis-guided approach for refractory major depression.",

Alemtuzumab can be administered in combination with other chemotherapeutic agents or as mono-therapy. Response rate to alemtuzumab is more than 90%. Alemtuzumab therapy is associated with improved survival of T-cell prolymphocytic leukemia patients."

"Sequential chemoimmunotherapy of fludarabine, mitoxantrone, and cyclophosphamide induction followed by alemtuzumab consolidation is effective in T-cell prolymphocytic leukemia",
"A central need in this historically refractory tumor is the controlled evaluation of multiagent chemotherapy and its combination with the currently most active single agent, alemtuzumab. ",
"FMC-A is a safe and efficient protocol in T-PLL, which compares favorably to published data.",
"Currently, the best treatment for T-PLL is IV alemtuzumab, which has resulted in very high response rates of more than 90% when given as frontline treatment and a significant improvement in survival. ",
"The patient failed to respond to standard ALL induction chemotherapy, but achieved complete remission following treatment with a fludarabine and alemtuzumab-based regimen.",
"Here we present a rare case of concurrent T-PLL and Kaposi sarcoma who achieved a complete hematologic and cytogenetic remission after a very short course of treatment with alemtuzumab.",
" Recent studies with single-agent alemtuzumab, an anti-CD52 monoclonal antibody, have shown improved response rates and survival in patients with T-cell prolymphocytic leukemia and cutaneous T-cell lymphoma. ",
"The CD52 antigen is expressed at high density on the malignant T-cells and therapy with alemtuzumab, a humanized IgG1 antibody that targets this antigen, has produced promising results. ",
"With the introduction of alemtuzumab, most patients who progressed despite treatment with pentostatin had a major response with a complete remission rate higher than that obtained with pentostatin when used as a first line.",
"Alemtuzumab (anti-CD52, Campath-1H) has recently been shown to be effective in the treatment of a range of hematological malignancies, including B-cell chronic lymphocytic leukemia and T-cell prolymphocytic leukemia.",
"Here we report the outcome of two patients with CD4-positive T cell prolymphocytic leukemia treated with CAMPATH-1H. Both patients responded rapidly to treatment and subsequently developed CD4 lymphopenia.",
"T-cell prolymphocytic leukemia (T-PLL) is a chemotherapy-resistant malignancy with a median survival of 7.5 months. Preliminary results indicated a high remission induction rate with the human CD52 antibody, CAMPATH-1H. ",
"CAMPATH-1H (30 mg) was administered intravenously 3 times weekly until maximal response. The overall response rate was 76% with 60% CR and 16% partial remission (PR). These responses were durable with a median disease-free interval of 7 months (range, 4-45 months). ",
"The conclusion is that CAMPATH-1H is an effective therapy in T-PLL, producing remissions in more than two thirds of patients. ",
"For example, most patients with T-cell prolymphocytic leukemia, including those with large tumor burdens and high peripheral white blood cell counts, will enter complete remission using the antibody CAMPATH-1H without any evidence of tumor lysis.",
"Overall response rate to FMC was 68%, comprising 6 complete remissions (all bone-marrow confirmed) and 11 partial remissions. Alemtuzumab consolidation increased the intent-to-treat overall response rate to 92% (12 complete remissions; 11 partial remissions). "

"Recently, it has been reported that moon phases correlate with the incidence of aneurysmal subarachnoid hemorrhage (SAH), however, another author found no such association. ",
"We found no correlation between incidence of aneurysmal SAH, location of the aneurysm, initial clinical presentation, or amount of subarachnoid blood and the lunar cycle. ",
"The moon influences neither the incidence of aneurysmal SAH nor the grade of initial neurological deterioration or amount of subarachnoid blood.",
"We did not observe any significant impact of the lunar cycle on the incidence of aneurysmal subarachnoid haemorrhage in 717 consecutive patients (p=0.84).",
"The impact of the lunar cycle on aneurysmal subarachnoid haemorrhage is a myth rather than reality.",
"An incidence peak for aneurysm rupture (28 patients) was seen during the phase of new moon, which was statistically significant (p < 0.001).",
"The lunar cycle seems to affect the incidence of intracranial aneurysm rupture, with the new moon being associated with an increased risk of aneurysmal SAH."

"Clinical trials have demonstrated that bapineuzumab, a humanized monoclonal antibody against the end terminus of amyloid plaques, is not effective for treatment of patients with Alzheimer's disease. The burden of beta amyloid plaques was reduced in response to bapineuzumab therapy. However, bapineuzumab therapy did not improve cognitive functioning and was associated with significant adverse effects in Alzheimer's disease patients."
] | [
"no"
] | [
" Thus far, results from two large phase 3 trial programs with bapineuzumab and solaneuzumab, respectively, have brought rather disappointing results.",
"More recently, in phase III studies, bapineuzumab has been discontinued because it did not prove clinically effective (despite its significant effect on biomarkers), while solaneuzumab has been found effective in slowing AD progression. ",
"Passive immunotherapy with monoclonal antibodies (mAbs) against Aβ is in late clinical development but recently the two most advanced mAbs, Bapineuzumab and Solanezumab, targeting an N-terminal or central epitope, respectively, failed to meet their target of improving or stabilizing cognition and function.",
"The marginal effects observed in recent clinical studies of solanezumab, targeting monomeric Aβ, and bapineuzumab, targeting amyloid plaques, prompted expert comments that drug discovery efforts in Alzheimer's disease should focus on soluble forms of Aβ rather than fibrillar Aβ deposits found in amyloid plaques.",
"Phase III trials showed that bapineuzumab failed to improve cognitive and functional performances in AD patients, and was associated with a high incidence of amyloid-related imaging abnormalities (ARIA).",
"Clinical trials on various drugs, including AN1792, bapineuzumab, and solanezumab, have been carried out; however, all trials have failed to demonstrate apparent clinical benefits. ",
"Despite the alteration in biochemical composition, all 3 immunized subjects exhibited continued cognitive decline.",
"Despite negative topline phase 3 clinical trial results for bapineuzumab and solanezumab in mild to moderate AD, findings from these trials and recent advances suggest renewed optimism for anti-amyloid therapies. ",
"The lack of progress in the development of disease-modifying therapy in Alzheimer's disease (AD) was highlighted recently by the cessation of a phase 3 clinical trial studying the effects of bapineuzumab on mild to moderate disease. No treatment benefit was apparent, whereas several serious side effects occurred more commonly in the treatment group compared to placebo. ",
"Clinical studies using the N-terminal-directed anti-Aβ antibody bapineuzumab have demonstrated reduced brain PET-Pittsburg-B signals, suggesting the reduction of Aβ plaques, and reduced levels of total and phosphorylated tau protein in the CSF of treated AD patients. Preclinical studies using 3D6 (the murine form of bapineuzumab) have demonstrated resolution of Aβ plaque and vascular burdens, neuritic dystrophy, and preservation of synaptic density in the transgenic APP mouse models.",
"The clinical results of the initial studies with bapineuzumab were equivocal in terms of cognitive benefit. The occurrence of vasogenic edema after bapineuzumab, and more rarely brain microhemorrhages (especially in Apo E ε4 carriers), has raised concerns on the safety of these antibodies directed against the N-terminus of the Aβ peptide. ",
" The most advanced of these immunological approaches is bapineuzumab, composed of humanized anti-Aβ monoclonal antibodies, that has been tested in two Phase II trials, demonstrating to reduce Aβ burden in the brain of AD patients. However, the preliminary cognitive efficacy of bapineuzumab appears uncertain. The occurrence of vasogenic edema, especially in apolipoprotein E 4 carriers, may limit its clinical use and have led to abandon the highest dose of the drug (2 mg/kg).",
"However, the preliminary cognitive efficacy of bapineuzumab, a humanized anti-Aβ monoclonal antibody, appears uncertain. Moreover, the occurrence of vasogenic edema and, more rarely, brain microhemorrhages, especially in apolipoprotein E ϵ4 carriers, have led to abandoning of the highest dose of the drug. ",
"However, the preliminary equivocal cognitive results obtained with bapineuzumab as well as the detrimental cognitive effects observed with semagacestat, a potent γ-secretase inhibitor, raise the possibility that targeting Aβ may not be clinically efficacious in AD. ",
"The patient received four bapineuzumab infusions over a 39 week period. During the course of this treatment, there was no remarkable change in cognitive impairment as determined by MMSE scores. Forty-eight days after the fourth bapineuzumab infusion was given, MRI revealed that the patient had developed lacunar infarcts and possible vasogenic edema, probably related to immunotherapy, but a subsequent MRI scan 38 days later demonstrated resolution of vasogenic edema. The patient expired due to acute congestive heart failure complicated by progressive AD and cerebrovascular accident 378 days after the first bapineuzumab infusion and 107 days after the end of therapy. Neuropathological and biochemical analysis did not produce evidence of lasting plaque regression or clearance of Aβ due to immunotherapy.",
"These results suggest that, in this particular case, bapineuzumab immunotherapy neither resulted in detectable clearance of amyloid plaques nor prevented further cognitive impairment.",
"Bapineuzumab has been shown to reduce Aβ burden in the brain of AD patients. However, its preliminary cognitive efficacy appears uncertain, particularly in ApoE ε4 carriers, and vasogenic edema may limit its clinical use. ",
"Bapineuzumab appears capable of reducing the cerebral beta-amyloid peptide burden in patients with Alzheimer's disease. However, particularly in APOE 4 carriers, its ability to slow disease progression remains uncertain, and vasogenic edema - a dose-limiting and potentially severe adverse reaction - may limit its clinical applicability.",
"The first is a phase 2 study of passive immunotherapy with bapineuzumab, a humanized anti-Abeta monoclonal antibody directed against the N-terminus of Abeta. This trial showed no differences within dose cohorts on the primary efficacy analysis. Exploratory analyses showed potential treatment differences on cognitive and functional endpoints in study completers and apolipoprotein E epsilon4 noncarriers. A safety concern was the occurrence of reversible vasogenic edema. ",
"The first passive immunotherapy trial with bapineuzumab, a humanized monoclonal antibody against the end terminus of Abeta, also encountered some dose dependent adverse events during the Phase II portion of the study, vasogenic edema in 12 cases, which were significantly over represented in ApoE4 carriers."

] | [
"effective in younger individuals"
] | [
"sHT in older people should be not regarded as a unique condition, and moderately old patients (aged <70-75 y) could be considered clinically similar to the adult population, albeit with a higher optimal TSH target value. Conversely, the oldest old subjects should be carefully followed with a wait-and-see strategy, generally avoiding hormonal treatment. The decision to treat elderly people is still an unresolved clinical challenge--first, due to a lack of appropriately powered randomized controlled trials of L-T4 in sHT patients, examining cardiovascular hard endpoints in various classes of age; and second, because of the negative effects of possible overtreatment.",
"Treatment of SCH with levothyroxine was associated with fewer IHD events in younger individuals, but this was not evident in older people. An appropriately powered randomized controlled trial of levothyroxine in SCH examining vascular outcomes is now warranted.",
"SCH appears to influence the postoperative outcome for patients by increasing the development of postoperative atrial fibrillation. However, it is still unproven whether preoperative thyroxine replacement therapy for patients with SCH might prevent postoperative atrial fibrillation after CABG.",
"Sustained normalization of thyroid function during l-T(4) replacement therapy significantly decreases baPWV in female subclinical hypothyroid patients with autoimmune chronic thyroiditis, suggesting the improvement of arterial stiffening and, consequently, possible prevention of cardiovascular disease.",
"Our results suggest that L-T(4) replacement therapy may be especially beneficial in female subclinical hypothyroid patients with high baseline baPWV and pulse pressure. The beneficial effects of L-T(4) replacement therapy in decreasing arterial stiffening and thus preventing cardiovascular disease might be limited to this sub-population.",
"Although a consensus is still lacking, the strongest evidence for a beneficial effect of levothyroxine replacement on markers of cardiovascular risk is the substantial demonstration that restoration of euthyroidism can lower both total and low-density lipoprotein-cholesterol levels in most patients with subclinical hypothyroidism.",
"However, the actual effectiveness of thyroid hormone substitution in reducing the risk of cardiovascular events remains to be elucidated.",
"Restoration of euthyroidism by levothyroxine (LT4) treatment may correct the lipid profile and cardiac abnormalities, especially in patients with an initially higher deviation from normality and higher serum TSH levels. Importantly, a strong association between SH and atherosclerotic cardiovascular disease, independent of the traditional risk factors, has been recently reported in a large cross-sectional survey (the Rotterdam Study). However, whether SH confers a high risk for cardiovascular disease, and whether LT4 therapy has a long-term benefit that clearly outweighs the risks of overzealous treatment in these individuals, remain topics of controversy."

"Evolutionary processes create both newly derived characteristics shared by related descendant lineages (homology) and \"false\" similarities which confound phylogenetic reconstruction (homoplasy). Homology arises by divergent evolution from a common ancestor and provides us with a phylogenetic signal, while homoplasy arises by convergent evolution or random coincidence. Homoplastic characters do not allows branch points and clade membership to be accurately estimated, as they may group unrelated taxa together. Such characters add \"noise\" in phylogenetic analysis and are not informative for the population genetics and the phylogenetic reconstruction of closely related taxa. In phylogenetic reconstruction, homoplasy leads to inaccurate conclusions about phylogenetic relationships among operational taxonomic units, and characters with high degree of homoplasy result in incongruences of cladistic relationships."

"The control region proved to be a less useful molecular marker for the population genetics and the phylogenetic reconstruction of closely related taxa in A. urticae than it has for other species. The extreme bias in adenine and thymine content (A+T=90.91%) probably renders this region highly susceptible to homoplasy, resulting in a less informative molecular marker.",
"Minimal homoplasy (consistency index = 0.9591) was detected among parsimony-informative SNPs, allowing for the generation of a highly accurate phylogenetic reconstruction of the CC398 clonal lineage.",
"These findings provide evidence for the occurrence of a high degree of homoplasy in the DR locus leading to convergent evolution to identical spoligotypes.

"Computational and phylogenetic analyses suggest that only some BH3 motifs arose by divergent evolution from a common ancestor (homology), whereas others arose by convergent evolution or random coincidence (homoplasy)",
"The high frequency of morphological homoplasy in pennatulaceans has led to many misinterpretations in the systematics of the group.",
"Conflict among data sources can be frequent in evolutionary biology, especially in cases where one character set poses limitations to resolution. Earthworm taxonomy, for example, remains a challenge because of the limited number of morphological characters taxonomically valuable. An explanation to this may be morphological convergence due to adaptation to a homogeneous habitat, resulting in high degrees of homoplasy. This sometimes impedes clear morphological diagnosis of species.",
"We also report one of the first findings of homoplasy in mitochondrial gene order, namely a shared relative position of trnV in unrelated isopod lineages.",

530cefaaad0bf1360c000009 | summary | What is known about the association between the use of selective serotonin reuptake inhibitors during pregnancy and risk for autism in offspring? | [
"Greater risk for autism spectrum disorders has been reported among mothers that have used selective serotonin reuptake inhibitors during pregnancy. However, others did not find an association between the use of selective serotonin reuptake inhibitors during pregnancy and risk for autism in offspring. Also, selective serotonin reuptake inhibitor use during pregnancy were associated with a greater number of gastrointestinal complaints in children with autism spectrum disorders."
] | [] | [
"In doing so, we examined whether two proposed risk factors - low birth weight (LBW), and in utero exposure to selective serotonin reuptake inhibitors (SSRIs) - are associated with greater behavioral homogeneity. Using data from the Western Australian Autism Biological Registry, this study found that LBW and maternal SSRI use during pregnancy were associated with greater sleep disturbances and a greater number of gastrointestinal complaints in children with ASD, respectively.",
"The outcome of one study suggested that children with autism were more likely to have a mother who was prescribed an SSRI during pregnancy.",
"A history of maternal (adjusted odds ratio 1.49, 95% confidence interval 1.08 to 2.08) but not paternal depression was associated with an increased risk of autism spectrum disorders in offspring. In the subsample with available data on drugs, this association was confined to women reporting antidepressant use during pregnancy (3.34, 1.50 to 7.47, P=0.003), irrespective of whether selective serotonin reuptake inhibitors (SSRIs) or non-selective monoamine reuptake inhibitors were reported.",
"In utero exposure to both SSRIs and non-selective monoamine reuptake inhibitors (tricyclic antidepressants) was associated with an increased risk of autism spectrum disorders, particularly without intellectual disability.",
"Repeated findings of elevated platelet serotonin levels in approximately one third of children with autism has led some to believe that dysfunctional serotonin signaling may be a causal mechanism for the disorder. Because serotonin is critical to fetal brain development, concerns have arisen regarding prenatal exposure to substances that manipulate serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs).",
"Though the majority of studies conducted in infants and children suggest prenatal exposure to SSRIs does not affect neurodevelopment, interpretation must be tempered given small sample sizes. The only published study that focused on prenatal SSRI exposure and ASD found an increased risk with exposure to SSRIs, especially during the first trimester. ",
"Among the potential environmental factors, hyperserotonemia during pregnancy and its effect on brain development could be playing a role in this prevalence raise. In the rodent model developed by Whitaker-Azmitia and colleagues, hyperserotonemia during fetal development results in a dysfunction of the hypothalamo-pituitary axis, affecting the amygdala as well as pro-social hormone oxytocin regulation. Dysfunction of the amygdala and abnormal oxytocin levels may underlie many clinical features of ASD. Selective serotonin reuptake inhibitors (SSRI) are the most widely used class of antidepressants drugs, and they are not contraindicated during pregnancy. ",
"In adjusted logistic regression models, we found a 2-fold increased risk of ASD associated with treatment with selective serotonin reuptake inhibitors by the mother during the year before delivery (adjusted odds ratio, 2.2 [95% confidence interval, 1.2-4.3]), with the strongest effect associated with treatment during the first trimester (adjusted odds ratio, 3.8 [95% confidence interval, 1.8-7.8]).",
"Although the number of children exposed prenatally to selective serotonin reuptake inhibitors in this population was low, results suggest that exposure, especially during the first trimester, may modestly increase the risk of ASD. ",
"Together, these results indicate that administration of SSRIs during a sensitive period of brain development results in long-lasting alterations in NE-LC circuit function in adults and may be useful in understanding the etiology of pervasive developmental disorders such as autism spectrum disorder.",
" Although several studies have not confirmed an increased risk for adverse neurodevelopment, a recent study observed an increased risk for autism spectrum disorders in prenatally exposed offspring. ",
"Considering the important role of serotonin in central nervous system development, more studies are needed to assess the possible adverse effects on long-term neurodevelopment."

"Downregulation of E-cadherin is a crucial event for epithelial to mesenchymal transition (EMT) in embryonic development and cancer progression. Overexpression of Snail1 (Snail), Snail2 (Slug), Zeb1, Twist, SIP1 and DeltaEF1 have been found to mediate E-cadherin repression, induce the mesenchymal markers vimentin and fibronectin, and finally promote the migratory and invasive capabilities in cancer cells."

"ifferential role of Snail1 and Snail2 zinc fingers in E-cadherin repression and epithelial to mesenchymal transition",
"nail1 (Snail) and Snail2 (Slug) are transcription factors that share a similar DNA binding structure of four and five C2H2 zinc finger motifs (ZF), respectively. Both factors bind specifically to a subset of E-box motifs (E2-box: CAGGTG/CACCTG) in target promoters like the E-cadherin promoter and are key mediators of epithelial-to-mesenchymal transition (EMT).",

"We demonstrate, for the first time, that thrombin induces E-cadherin repression by stimulating snail-2 (SLUG) transcription factor expression,",
"Mutation of the putative GSK-3β phosphorylation sites (S92/96A or S100/104A) enhanced the Slug/Snail2-mediated EMT properties of E-cadherin repression and vimentin induction, compared with wild-type Slug/Snail2.",
"xpression of E-cadherin, a hallmark of epithelial-mesenchymal transition (EMT), is often lost due to promoter DNA methylation in basal-like breast cancer (BLBC),",
"Here, we identified that Snail interacted with Suv39H1 (suppressor of variegation 3-9 homolog 1), a major methyltransferase responsible for H3K9me3 that intimately links to DNA methylation. ",
"We showed that Snail interacted with Suv39H1 and recruited it to the E-cadherin promoter for transcriptional repression.",
"Knockdown of Suv39H1 restored E-cadherin expression by blocking H3K9me3 and DNA methylation and resulted in the inhibition of cell migration, invasion and metastasis of BLBC.",
"9a interacts with Snail and is critical for Snail-mediated E-cadherin repression in human breast cancer",
"Here, we have determined that methylation of histone H3 on lysine 9 (H3K9me2) is critical for promoter DNA methylation of E-cadherin in three TGF-β-induced EMT model cell lines, as well as in CLBC cell lines.",
"Further, Snail interacted with G9a, a major euchromatin methyltransferase responsible for H3K9me2, and recruited G9a and DNA methyltransferases to the E-cadherin promoter for DNA methylation.",
"Knockdown of G9a restored E-cadherin expression by suppressing H3K9me2 and blocking DNA methylation. This resulted in inhibition of cell migration and invasion in vitro and suppression of tumor growth and lung colonization in in vivo models of CLBC metastasis.",
"ZEB1, which targets E-cadherin repression, is a transcriptional regulator that has been implicated in EMT, and is associated with uterine and colorectal cancers.",
"The introduction or knockdown of ZEB1 expression in bladder carcinoma cell lines showed enhanced or reduced migration and invasive potential, respectively.",
"However, in vitro assays showed enhanced or reduced migration and invasion after the introduction or reduction of ZEB1, respectively, in transfected bladder cell lines.",
"Finally, we showed aberrant IL-6 production and STAT3 activation in MCF-7 cells that constitutively express Twist, a metastatic regulator and direct transcriptional repressor of E-cadherin. To our knowledge, this is the first study that shows IL-6 as an inducer of an EMT phenotype in breast cancer cells and implicates its potential to promote breast cancer metastasis.",
"unctional loss of the cell-cell adhesion molecule E-cadherin is an essential event for epithelial-mesenchymal transition (EMT), a process that allows cell migration during embryonic development and tumour invasion. In most carcinomas, transcriptional repression has emerged as the main mechanism responsible for E-cadherin downregulation.",
"Here, we report the identification of class I bHLH factor E2-2 (TCF4/ITF2) as a new EMT regulator.",
"E-cadherin repression mediated by E2-2 is indirect and independent of proximal E-boxes of the promoter.",

"Slug mRNA was shown to be over-expressed in adenocarcinoma and inversely correlated to E-cadherin expression.",
"Overexpression of Slug in OE33 mediated E-cadherin repression and induced the mesenchymal markers vimentin and fibronectin.",
"SIP1 and deltaEF1 each dramatically down-regulated the transcription of E-cadherin in NMuMG cells through direct binding to the E-cadherin promoter.",

"Analysis of E-cadherin promoter activity and chromatin immunoprecipitation identified deltaEF1 as direct transcriptional repressor of E-cadherin.",
"In human cancer cells, transcript levels of deltaEF1 correlated directly with the extent of E-cadherin repression and loss of the epithelial phenotype.",
"RNA interference-mediated downregulation of deltaEF1 in cancer cells was sufficient to derepress E-cadherin expression and restore cell to cell adhesion, suggesting that deltaEF1 is a key player in late stage carcinogenesis.",
"TGF-beta-induced the expression of Ets1, which in turn activated deltaEF1 promoter activity. Moreover, up-regulation of SIP1 and deltaEF1 expression by TGF-beta was suppressed by knockdown of Ets1 expression. ",

Mice deficient in desmin, the muscle-specific member of the intermediate filament gene family, display defects in all muscle types and particularly in the myocardium. Desmin null hearts develop cardiomyocyte hypertrophy and dilated cardiomyopathy (DCM) characterized by extensive myocyte cell death, calcific fibrosis and multiple ultrastructural defects. Desmin defects were also recently identified in 1 familial dilated cardiomyopathy."

Mutations in the central 2B domain of DES cause skeletal muscle disease that typically precedes cardiac involvement. However, the prevalence of DES mutations in dilated cardiomyopathy (DCM) without skeletal muscle disease is not known.",
"The lack of severe disruption of cytoskeletal desmin network formation seen with mutations in the 1A and tail domains suggests that dysfunction of seemingly intact desmin networks is sufficient to cause DCM.",
"According to the predominant view, desmin mutations cause dilated cardiomyopathy (DCM). We evaluated a family with restrictive cardiomyopathy (RCM) associated with a novel desmin mutation and reviewed recent reports regarding the frequency of RCM in patients with desmin myopathy.",
"Dilated cardiomyopathy (DCM) is characterized by enlargement and dilation of all heart compartments associated with serious decrease of its contractile function. DCM hallmark is the combination of dystrophic and hypertrophic alterations of cardiomyocytes. Since the power output of cardiac cells is directly related to remodeling of their contractile machinery we investigated expression of selected contractile and cytoskeletal proteins in the left ventricle of DCM patients using immunoblotting. The content of the recognized protein markers of cardiomyocyte hypertrophy such as tubulin, desmin and slow skeletal myosin heavy chain isoform, MHCbeta, was significantly elevated in DCM compared to normal myocardium.",
"In contrast, overexpression of desmin filaments by itself is not detrimental to the heart. Although loss-of-function studies have been more limited, ablation of the desmin gene causes mitochondrial dysfunction and apoptosis, resulting in cardiomyopathy in mice. From function studies, abnormal desmin aggregation and disruption of the desmin networks resulting from expression of either mutant desmin or mutant CryAB have been shown to remodel the heart and compromise cardiac function, suggesting their synergistic roles in disease pathogenesis.",
"A missense mutation in the desmin gene (DES) causes DCM in a human family.",
"Mice deficient in desmin, the muscle-specific member of the intermediate filament gene family, display defects in all muscle types and particularly in the myocardium. Desmin null hearts develop cardiomyocyte hypertrophy and dilated cardiomyopathy (DCM) characterized by extensive myocyte cell death, calcific fibrosis and multiple ultrastructural defects. Several lines of evidence suggest impaired vascular function in desmin null animals.",
"Familial DCM is commonly inherited as autosomal dominant trait; less frequently it is autosomal recessive, X-linked or matrilinear. The disease is clinically and genetically heterogeneous. Genes causally linked to this phenotype include dystrophin, dystrophin-associated glycoproteins, actin, desmin, beta-miosin heavy chain, cardiac troponin T, and mitochondrial DNA genes, mostly transfer RNAs.",

52fa74252059c6d71c00005b | summary | Why are insulators necessary in gene therapy vectors? | [
"a) They inhibit oncogene activation upon vector integration and b) They maximize the probability of vector expression upon integration in heterochromatinic regions",
"The presence of insulators in gene therapy vectors is necessary because these elements have the ability to help overcome the problem of position effects, caused due to random integration of the therapeutic genes in the host cell genome."
] | [] | [
"hromatin insulators separate active transcriptional domains and block the spread of heterochromatin in the genome. Studies on the chicken hypersensitive site-4 (cHS4) element, a prototypic insulator, have identified CTCF and USF-1/2 motifs in the proximal 250 bp of cHS4, termed the \"core\", which provide enhancer blocking activity and reduce position effects.",
"An attractive solution to the problem of oncogene activation is the inclusion of insulators/enhancer-blockers in the viral vectors.",
"We propose the incorporation of chromatin insulators in the design of gene therapy vectors to overcome the problem of position effects. Chromatin insulators are protein-binding DNA elements that lack intrinsic promoter/enhancer activity but shelter genes from transcriptional influence of surrounding chromatin.",
"The design and incorporation of effective chromatin insulator sequences in the next generation of gene therapy vectors should lead to improved and more predictable expression of therapeutic transgenes and constitute an important step toward clinically effective gene therapy."

"It has been well-documented that iron deficiency is the cause of restless leg syndrome. Magnesium and ferritin were also associated with restless leg syndrome."

"We describe a unique case of a 23-yr-old female patient affected by a homozygous loss of function mutation in the L-ferritin gene, idiopathic generalized seizures, and atypical restless leg syndrome (RLS). We show that L chain ferritin is undetectable in primary fibroblasts from the patient, and thus ferritin consists only of H chains.",
"Our results demonstrate for the first time the pathophysiological consequences of L-ferritin deficiency in a human and help to define the concept for a new disease entity hallmarked by idiopathic generalized seizure and atypical RLS.",
"These results when viewed along with prior RLS SPECT and autopsy studies of DAT, and cell culture studies with iron deficiency and DAT, suggest that membrane-bound striatal DAT, but not total cellular DAT, may be decreased in RLS.",
" Compared with the PD or healthy group, the level of serum ferritin and the H-reflex latency of tibial nerve were significantly decreased in PD with RLS group (P < 0.05).",
"Deficiency of iron and decreased inhibition function of spinal cord may lead to the occurrence of RLS in PD patients. ",
"Association of iron deficiency with febrile seizures, pica, breath holding spells, restless leg syndrome and thrombosis is increasingly being recognized.",
" Iron status was generally poor among regular blood donors, especially in women, with a high incidence of iron depletion (>20%) and RLS (18%). ",
"Iron status is poor in regular blood donors, restless legs syndrome is common, and the routine iron supplementation is insufficient. ",
"Furthermore, there appears to be an association between iron deficiency and those suffering from Restless Leg Syndrome (RLS). ",
"The authors propose that PPIs, such as omeprazole, may interfere with iron absorption in certain patients and that a subpopulation of patients who develop significant iron deficiency characterized by low serum ferritin levels while on PPIs may also develop RLS-like symptoms (including RLSAP).",
"Clinical studies have implicated the dopaminergic system in RLS, while others have suggested that it is associated with insufficient levels of brain iron. ",
"The results are consistent with the hypothesis that a primary iron insufficiency produces a dopaminergic abnormality characterized as an overly activated dopaminergic system as part of the RLS pathology.",
"RLS may also be secondary to a number of conditions including iron deficiency, pregnancy and end-stage renal failure and, perhaps, neuropathy.",
"The pathogenesis of RLS probably involves the interplay of systemic or brain iron deficiency and impaired dopaminergic neurotransmission in the subcortex of the brain. ",
"All patients showed low levels of ferritin and iron supplementation was effective in five cases. ",
"Clinical and animal studies that support the benefits of iron supplementation, independent of increasing hemoglobin, such as those on immune function, physical performance, thermoregulation, cognition, and restless leg syndrome and aluminum absorption is the subject of this narrative review.",
"Restless leg syndrome (RLS) and periodic limb movement disorder (PLMD) are considered to be a continuum of a neurological sleep disorder associated with abnormal iron metabolism or deficiency. I describe a case of RLS and PLMD in a cystic fibrosis patient with iron deficiency from chronic hemoptysis. This is the first case that reports RLS and PLMD manifesting from iron deficiency caused by chronic hemoptysis in advanced cystic fibrosis lung disease.",
"Restless leg syndrome manifested by iron deficiency from chronic hemoptysis in cystic fibrosis.",
"Diurnal effects on motor control are evident in the human disease of Restless Leg Syndrome (RLS), which is purported to be linked to brain iron deficiency as well as alterations in dopaminergic systems. ",
"Iron deficiency in the central nervous system is known to cause motor impairment and cognitive deficits; more recently, it has been suggested that it may play a role in the pathophysiology of the restless leg syndrome. ",
"Restless leg syndrome (RLS), aging, pregnancy, uraemia, iron deficiency, polyneuropathy are some of the common causes of secondary PLMD.",
"The syndrome is increasingly often diagnosed, particularly in association with iron deficiency, during pregnancy, in chronic renal failure and in patients with peripheral neuropathy. ",
"Clinical, EEG, electromyographic and polysomnographic studies in restless legs syndrome caused by magnesium deficiency.",
"A frequent polymorphism in BTBD9 was significantly associated with serum ferritin. This polymorphism has previously been associated with RLS, but not low iron stores in blood donors."

"To investigate the gain of regulatory elements throughout vertebrate evolution, we identified genome-wide sets of putative regulatory regions for five vertebrates, including humans. These putative regulatory regions are conserved nonexonic elements (CNEEs), which are evolutionarily conserved yet do not overlap any coding or noncoding mature transcript. We then inferred the branch on which each CNEE came under selective constraint. Our analysis identified three extended periods in the evolution of gene regulatory elements.

"Yes, it is associated with peripheral neuropathy.",
"Yes, pesticide exposure is associated with delayed polyneuropathy. Electrophysiological studies have revealed three characteristic phenomena: (i) repetitive firing following a single stimulus; (ii) gradual reduction in twitch height or compound muscle action potential followed by an increase with repetitive stimulation (the 'decrement-increment response'); and (iii) continued reduction in twitch height or compound muscle action potential with repetitive simulation ('decrementing response'). Pesticide exposure was also implicated in Alzheimer's disease, suicide attempts and affective disorders."
] | [
"yes"
] | [
"As the syndrome occurred after the acute cholinergic syndrome but before organophosphate-induced delayed polyneuropathy, the syndrome was called 'intermediate syndrome'.",
"The characteristic features of the IMS are weakness of the muscles of respiration (diaphragm, intercostal muscles and accessory muscles including neck muscles) and of proximal limb muscles. Accompanying features often include weakness of muscles innervated by some cranial nerves. It is now emerging that the degree and extent of muscle weakness may vary following the onset of the IMS. ",
"Electrophysiological studies following OP poisoning have revealed three characteristic phenomena: (i) repetitive firing following a single stimulus; (ii) gradual reduction in twitch height or compound muscle action potential followed by an increase with repetitive stimulation (the 'decrement-increment response'); and (iii) continued reduction in twitch height or compound muscle action potential with repetitive simulation ('decrementing response'). ",
"Organophosphate-induced delayed polyneuropathy is a sensory-motor distal axonopathy which usually occurs after exposure of certain OP insecticides. Neuropathies due to ingestion of OPs have rarely been reported in the literature.",
"We report a patient with serious organophosphorus-induced delayed neuropathy due to malathion injection. The patient was a 32-year-old female who self-injected undetermined amounts of malathion over the median nerve trace on the forearm crease in a suicide attempt which resulted in peripheral neuropathy.",
" Acutely, these patients present with cholinergic crisis; intermediate syndrome and delayed polyneuropathy are other sequel of this form of poisoning.",
"There was no strong evidence of irreversible peripheral nerve damage following acute OP poisoning, however further studies are required.",
"Particular interactions are also addressed, such as those of pesticides acting as endocrine disruptors, the cumulative toxicity of organophosphates and organochlorines resulting in estrogenic effects and the promotion of organophosphate-induced delayed polyneuropathy.",
"The multivariate analyses showed that the population living in areas with high pesticide use had an increased risk for Alzheimer's disease and suicide attempts and that males living in these areas had increased risks for polyneuropathies, affective disorders and suicide attempts. ",
"These compounds cause four important neurotoxic effects in humans: the cholinergic syndrome, the intermediate syndrome, organophosphate-induced delayed polyneuropathy (OPIDP) and chronic organophosphate-induced neuropsychiatric disorder (COPIND). ",
"An 18-year-old woman and a 22-year-old man were admitted to the hospital with weakness, paresthesia, and gait disturbances at 35 and 22 days, respectively, after ingesting dimethyl-2,2-dichloro vinyl phosphate (DDVP). Neurological examination revealed weakness, vibration sense loss, bilateral dropped foot, brisk deep tendon reflexes, and bilaterally positive Babinski sign. Electroneurography demonstrated distal motor polyneuropathy with segmental demyelination associated with axonal degeneration prominent in the distal parts of both lower extremities.",
"Sensory complaints and electrodiagnostic findings consistent with polyneuropathy were found in a minority (3/7) of subjects 28 years after an acute toxic arsenic exposure.",
"Organophosphate-induced delayed polyneuropathy (OPIDP) is a rare toxicity resulting from exposure to certain organophosphorus (OP) esters. ",
"Therefore, OPIDP may develop only after very large exposures to insecticides, causing severe cholinergic toxicity.",
"Several studies have reported the occurrence of sensory neuropathy with exposure to chlorpyrifos and other organophosphorus insecticides, at levels not associated with overt toxicity. ",
"We found no evidence of sensory neuropathy or isolated peripheral abnormalities among subjects with long-term chlorpyrifos exposure at levels known to be associated with the manufacturing process.",
"Persistent, mainly motor, impairment of the peripheral nervous system was found in men two years after OP poisoning, in particular in severe occupational and intentional poisonings with neuropathic OPs. This finding is possibly due to remaining organophosphate induced delayed polyneuropathy.",
"Besides the well known acute cholinergic toxicity, these compounds may cause late-onset distal polyneuropathy occurring two to three weeks after the acute exposure. ",
"Electromyography demonstrated motor weighed sensory-motor polyneuropathy with axonal degeneration significant in the distal parts of bilateral lower extremities. ",
"The two cases are presented here since organophosphate poisonings are common in our country, and since late-onset polyneuropathy is not a well known clinical presentation as acute toxicity.",
"The course of organophosphate-induced delayed polyneuropathy (OPIDP) in humans has not been quantitatively measured in epidemiologic studies.",
"The persistence of deficits in motor strength in all severely poisoned patients regardless of pesticide type was unexpected, and may reflect persistent cholinergic blockade or intermediate syndrome, neuropathy, or a combination of these.",
"The findings showed a strong association between exposure to OP concentrate and neurological symptoms, but a less consistent association with sensory thresholds. ",
"Following accidental or suicidal exposure, these anticholinesterases lead to three well defined neurological syndromes i.e. initial life threatening acute cholinergic crisis which often requires management in intensive care unit, intermediate syndrome in which cranial nerve palsies, proximal muscle weakness and respiratory muscle weakness are common and patients often require respiratory support and delayed organophosphate induced polyneuropathy.",
"[Late onset polyneuropathy due to exposure to organophosphates].",
" Less often a polyneuropathic syndrome of late onset may occur.",
"On electromyography there was sensomotor peripheral polyneuropathy, which was primarily axonal and predominantly motor and distal. Peripheral nerve biopsy confirmed the presence of 'dying back' type axonopathy. ",
"Agricultural workers chronically exposed to organophosphate insecticides, without adequate protection, have an increased risk of developing late onset neuropathy due to organophosphates. ",
"Epidemiologic studies on pesticides have found associations with long-term effects on health mainly in three fields: cancer (especially hematological cancer), neurotoxic effects (polyneuropathy, neuro-behavioral hazards, Parkinson's disease), and reproductive disorders (infertility, birth defects, adverse pregnancy outcomes, perinatal mortality). ",
"EMG studies showed evidence of partial denervation of the anterior tibial group of muscles and flexor digiti minimi in 2 of the 30 workers (6.7%) who underwent EMG examination.",
"Neurological symptoms consist in cerebro-organic disfunctions, locomotory disorders reminiscent of multiple sclerosis or M. Parkinson, and sensory, motoric and vegetative polyneuropathy, leading, for instance, to cardiovascular regulatory disorder like sympathicotonia or, orthostatic hypotonia. ",
"Thirty percent of patients had definite or possible exposure to organophosphate pesticides, and the peak use coincides with the peak incidence of Guillain-Barré syndrome.",
"These results suggest that previously reported cases of organophosphate-induced delayed polyneuropathy may represent only the worst disease in a spectrum of impairment, a sequela of exposure that may be much more common than previously thought.",
"It is suggested that the main cause of nervous lesions in these cases was the complex effect of pesticides.",
"Delayed polyneuropathy develops within 1 to 3 weeks and abates after 6 to 12 months. ",
"Isolated case reports have circumstantially linked the use of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) to polyneuropathy.",
"Thus, the weight of evidence indicates that 2,4-D is an unlikely cause of polyneuropathy.",
"A patient is reported presenting a cerebellar disorder developing about 5 weeks after acute exposure to an organophosphate insecticide. ",
"Less well known, but more complex and idiosyncratic, is the potential for some agents to produce a delayed and progressive polyneuropathy--Organophosphorus Induced Delayed Neurotox-icity (OPIDN).",
" It is also quite probable that human neurotoxicity may be a potential hazard from exposure to more than the handful of organophosphorus pesticides that have been described in the literature.",
"In the present study the electroencephalograms of 3 of a group 10 workmen, who had been continually exposed to hexachlorcyclohexane, show pathological findings. The electromyograms of 8 of these 10 workman demonstrate a disturbance of the peripherical motoneuron. All probands, who exhibit o pathological EEG, also show a polyneuropathy.",
"Many organophosphorus compounds, including the organophosphate insecticides, may cause polyneuropathy of delayed onset.",
"Nevertheless, we describe a patient with delayed polyneuropathy after suicidal ingestion of parathion.",
"Following acute organophosphorus (OP) poisoning patients complain of numbness without objective sensory abnormalities or other features of OP induced delayed polyneuropathy. "

56f3f94109dd18d46b000001 | summary | What is the methodological principle of ChIA-PET? | [
"Chromatin interaction analysis with paired-end tag sequencing (ChIA-PET) is a new technology to study genome-wide long-range chromatin interactions bound by protein factors. To minimize non-specific noise and reduce complexity, as well as to increase the specificity of the chromatin interaction analysis, chromatin immunoprecipitation (ChIP) is used against specific protein factors to enrich chromatin fragments of interest before proximity ligation. Combining Chromatin Immunoprecipitation (ChIP), proximity ligation and high-throughput sequencing, ChIA-PET provides a global and unbiased interrogation of higher-order chromatin structures associated with specific protein factors. Here, we propose a statistical model taking into account the genomic distance relationship, as well as the general propensity of anchors to be involved in contacts overall.",
"Chromatin interaction analysis with paired-end tag sequencing (ChIA-PET) is a new technology to study genome-wide long-range chromatin interactions bound by protein factors. It converts functional chromatin structure into millions of short tag sequences. By combining Chromatin Immunoprecipitation (ChIP), proximity ligation and high-throughput sequencing, ChIA-PET provides a global and unbiased interrogation of higher-order chromatin structures associated with specific protein factors."

54f09a5894afd6150400001c | summary | What is known about the value of mindfulness interventions in prostate cancer patients? | [
"In prostate cancer patients, mindfulness interventions were well accepted and were effective in reducing stress, anxiety, avoidance, fear of cancer recurrence, cortisol levels and blood pressure, and improving quality of life, sleep quality and immune system functioning. In addition, mindfulness interventions promoted initiation of healthy dietary changes and decreases the rate of PSA increase and may slow the rate of tumor progression in cases of biochemically recurrent prostate cancer."
] | [] | [
"Participants reported regular mindfulness training practice, and there was a significant correlation between mindfulness training practice and changes in both initiation and maintenance of the change in A:V. These pilot results provide encouraging evidence for the feasibility of a dietary program that includes mindfulness training in supporting dietary change for men with recurrent prostate cancer and invite further study to explore the possible role of mindfulness training as a means of supporting both initiation of dietary changes and maintenance of those changes over time.",
"FINDINGS: Following the 6-week MBSR program, patients showed improvements in stress and anxiety (p < .05); caregivers' psychological and QOL also improved but were not statistically significant. Both patients and caregivers had decreases in cortisol at Weeks 1 and 3 (p < .05) but not at Week 6. Similar to cortisol levels at Week 6, salivary interleukin-6 levels were lower overall (before/after an MBSR-C session), compared with Week 1 for patients and caregivers. CONCLUSIONS: MBSR-C may be a beneficial intervention for reducing stress, anxiety, cortisol levels, and symptoms in advanced-stage cancer patients and may also benefit caregivers.",
"ESULTS: Significant improvements were observed for anxiety (p = 0.027), avoidance (p = 0.032), and mindfulness skills (p = 0.019), with a trend for a reduction in fear of cancer recurrence (p = 0.062).",
"CONCLUSIONS: Mindfulness-based group interventions appear to have utility in this patient group and show promise for reducing anxiety, avoidance, and fear of cancer recurrence. ",
" Linear mixed modeling showed significant improvements in overall symptoms of stress which were maintained over the follow-up period. Cortisol levels decreased systematically over the course of the follow-up. Immune patterns over the year supported a continued reduction in Th1 (pro-inflammatory) cytokines. Systolic blood pressure (SBP) decreased from pre- to post-intervention and HR was positively associated with self-reported symptoms of stress. CONCLUSIONS: MBSR program participation was associated with enhanced quality of life and decreased stress symptoms, altered cortisol and immune patterns consistent with less stress and mood disturbance, and decreased blood pressure. ",
"Significant improvements were seen in overall quality of life, symptoms of stress, and sleep quality, but these improvements were not significantly correlated with the degree of program attendance or minutes of home practice. ",
"CONCLUSIONS: MBSR program enrollment was associated with enhanced quality of life and decreased stress symptoms in breast and prostate cancer patients, and resulted in possibly beneficial changes in hypothalamic-pituitary-adrenal (HPA) axis functioning. ",
"Significant improvements were seen in overall quality of life, symptoms of stress, and sleep quality. Although there were no significant changes in the overall number of lymphocytes or cell subsets, T cell production of IL-4 increased and IFN-gamma decreased, whereas NK cell production of IL-10 decreased.",
"CONCLUSIONS: MBSR participation was associated with enhanced quality of life and decreased stress symptoms in breast and prostate cancer patients. This study is also the first to show changes in cancer-related cytokine production associated with program participation.",
"CONCLUSIONS: Our small study provides evidence that a plant-based diet delivered in the context of MBSR decreases the rate of PSA increase and may slow the rate of tumor progression in cases of biochemically recurrent prostate cancer."

530cefaaad0bf1360c00000e | summary | What is known about prostate cancer screening in the UK ? | [
"There is still no national screening programme established in the UK. Prostate cancer screening of asymptomatic men is not recommended by the National Screening Council at present and is not encouraged in the NHS. However, PSA tests are being performed for prostate cancer screening. The CAP and ProtecT trials are aimed to evaluate prostate cancer screening in the UK."

"Screening for early disease has been available for many years, but there is still no national screening programme established in the United Kingdom.",
"Latest results from the UK trials evaluating prostate cancer screening and treatment: the CAP and ProtecT studies.",
"The CAP and ProtecT trials (ISRCTN92187251 and ISRCTN20141217) will help resolve the prostate cancer screening debate, define the optimum treatment for localised disease and generate evidence to improve men's health.",
"Increased usage of Prosdex leads to more informed decision making, the key aim of the UK Prostate Cancer Risk Management Programme. ",
"To date, the AIDIT team has established a website to facilitate communication between project collaborators (www.impact-study.co.uk), has been represented at several international meetings and has facilitated a conference for the IMPACT study to bring together international research teams, clinicians and policy makers.",
" This prospective questionnaire study was nested within the case-finding component of the ProtecT (prostate testing for cancer and treatment) feasibility study (ISRCTN20141297). ",
"The UK NHS Executive has issued extensive guidance stressing the importance of adequate counselling prior to performing this test. ",
"To examine the pattern of use of prostate-specific antigen (PSA) testing in a UK region, where National Health Service policy does not recommend screening for prostate cancer. ",
"In all, 165 862 PSA tests were performed on 84 669 men, and over a third of men aged > or = 50 years had at least one PSA test. Men aged < 50 years accounted for 12.9% of first tests. The proportion of tests from primary care increased from 47.2% in 1993 to 67.0% in 1999. The mean age of men tested once decreased from 65.6 to 61.9 years (P trend < 0.001) and the proportion with an elevated PSA level also declined during the period. Repeat testing increased with PSA level (P < 0.001) but 29.4% of men with a PSA level of < or = 4 ng/mL also had repeat testing. Raised PSA values were more common from hospital than primary care (32.4% vs 20.6%, P < 0.001) and in older men. Test rates varied 100-fold across general practices, a finding not explained by sociodemographic factors, but one which reflects differential adherence to national guidelines, suggesting that general practitioners are key targets for attempting to rationalise the use of the PSA test. ",
"These findings suggest that PSA screening is taking place against evidence-based advice and has resulted in over 20 000 men being designated as having a raised PSA level, creating a need for further assessment.",
"There is no current prostate cancer screening programme in the UK. ",
"Prostate cancer screening of asymptomatic men is not recommended by the National Screening Council at present and is not encouraged in the NHS.",
"We used a nested case-control design on data from men in four prospective studies (from the UK, Maryland in the USA, and two from Finland) with available stored serum samples to determine whether there was an advantage in measuring both free prostate-specific antigen (PSA) and total PSA as a potential screening test for prostate cancer.",
"Some respondents were reluctant to give the leaflet to people enquiring about screening for prostate cancer, for example, because they thought that the leaflet would cause anxiety, or because prostate cancer screening was not freely available locally. ",
"National guidance (executive letter) EL(97)12 stated that population screening should not be provided by the NHS, or be offered to the public until there is effective screening technology for prostate cancer. ",
"This postal questionnaire survey reveals that 81% (95% CI 75% to 87%) of responding general practitioners in North Staffordshire agreed with EL(97)12 and one in ten said that the executive letter changed their views, suggesting that such national guidance has an effect."
