What are the computational methods for the prediction of beta-barrel transmembrane proteins?

Computational tools have been developed for beta-barrel transmembrane protein discrimination, topology prediction and prediction of their structural features. Initial methods developed for the prediction of the transmembrane beta strands were based on hydrophobicity analysis, using sliding windows along the sequence, in order to capture the alternating patterns of hydrophobic-hydrophilic residues of the transmembrane strands, or using generalized secondary structure prediction methods. Other approaches included the construction of special empirical rules using amino-acid propensities and prior knowledge of the structural nature of the proteins, and the development of Neural Network-based predictors to predict the location of alpha-carbon atoms with respect to the membrane. During the last few years, other more refined methods, appeared, including: Neural Networks, Hidden Markov Models, Support Vector Machines, k-Nearest Neighbors, Radial Basis Functions, Bayesian Networks, Genetic Algorithms, Mahalanobis Discriminant Functions, Cellular Automata, N-to-1 Extreme Learning Machines. Hidden Markov Model-based methods are among the most successful in topology prediction, being able to capture the unique architecture of beta-barrel transmembrane proteins. Consensus methods, as well as pipelines of several related tools (e.g. subcellular localization prediciton, alpha-helical transmembrane protein prediction, signal-peptide/lipoprotein prediction) have also used for discriminating beta-barrel transmembrane proteins. Recently, a number of methods for predicting more detailed structural features (e.g. surface accessibility, residue contacts, even detailed atomic 3D models) tailored to beta-barrel transmembrane proteins have been developed, based on knowledge-based potential functions, graph theoretic models, physical models and multi-tape S-attribute grammars. Methods/tools falling in the aforementioned classes are (listed in alphabetical order): BBF (beta-barrel finder), BETAWARE, BOCTOPUS, BOMP, BTMX (Beta barrel TransMembrane eXposure), HHomp, HMM-B2TMR, OMBBpred, PROFtmb, PRED-TMBB, TMB-Hunt, TBBPred, TMBETAPRED-RBF, TMBHMM, TransFold, TMBpro, TMBKNN, Wimley

List programs suitable for pharmacophore modelling

A pharmacophore is an abstract description of molecular features which are necessary for molecular recognition of a ligand by a biological macromolecule. The IUPAC defines a pharmacophore to be "an ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target and to trigger (or block) its biological response". A pharmacophore model explains how structurally diverse ligands can bind to a common receptor site. Furthermore pharmacophore models can be used to identify through denovo design or virtual screening novel ligands that will bind to the same receptor. Nowadays there are many programs suitable for pharmacophore modelling such as LigandScout, Discovery Studio, Catalyst, PharmaGist, Genetic Algorithm Similarity and Molecular Operating Environment.

What is ESN364?

systemic administration of an NK3R antagonist (ESN364) prolongs the LH interpulse interval in ovarectomized ewes and significantly lowers plasma LH and FSH concentrations in castrated nonhuman primates (Macaca fascicularis). Moreover, daily oral dosing of ESN364 throughout the menstrual cycle in M fascicularis lowered plasma estradiol levels in a dose-dependent manner, although nadir levels of estradiol were maintained well above menopausal levels. Nevertheless, estradiol levels during the follicular phase were sufficiently inhibited at all doses to preclude the triggering of ovulation as evidenced by the absence of the LH surge and failure of a subsequent luteal phase rise in plasma progesterone concentrations, consistent with the absence of normal cycle changes in the uterus. Apart from the point at surge, FSH levels were not altered over the course of the menstrual cycle. These effects of ESN364 were reversible upon cessation of drug treatment. ESN364 was well-tolerated and rapidly bioavailable with linear pharmacokinetics and no drug accumulation with repeated, daily oral administration. Drug treatment dose-dependently decreased basal LH, but not FSH, and consequently decreased estradiol and progesterone (in women) as well as testosterone (in men). The hormonal changes in women corresponded to delayed ovulation, decreased endometrial thickening, impeded follicular maturation, and prolongation of the menstrual cycle. Drug effects were rapidly reversible. Oral administration of the NK3R antagonist, ESN364, suppressed the hypothalamic-pituitary-gonadal axis in healthy volunteers by selective modulation of gonadotropin secretion, leading to a restrained decrease in ovarian hormone levels in women. These results suggest that ESN364 may offer therapeutic benefit in the treatment of women's health disorders with a mitigated risk of menopausal-like adverse events.

How is yellow fever virus transmitted?

Yellow fever virus is transmitted by mosquitoes and is restricted to Africa, Central and South America and the Caribbean. Yellow fever virus is a flavivirus, and there is only one antigenic type. It was taken to the Americas by the early slave traders, and nowadays reported in Africa, America, Asia and Europe. Yellow fever virus is transmitted by two different cycles: -from human to human by the mosquito Aedes aegypti; which is well-adapted to breeding around human habitations; the infection can be maintained in this way as ‘urban’ yellow fever. -from infected monkeys to humans by mosquitoes such as Haemagogus. This is ‘jungle’ yellow fever and is seen in Africa and South America. Yellow fever is not transmitted directly from human to human by day-to-day contact, but transmission from ill patients to healthcare workers has been reported, notably after needlestick injury.

List co-morbidities that may occur together with "Stiff man Syndrome"

SMS (Stiff man Syndrome) is is a rare disorder of the central nervous system of probable autoimmune origin and as such is associated with other autoimmune diseases, such as Insulin Dependent Diabetes Mellitus . GAD-65 is a dominant auto-antigen that is found both in in stiff-man syndrome and insulin-dependent diabetes mellitus. TRAB -positive Graves' disease has been reported to occur together with SMS. In a subgroup of patients with the stiff-man syndrome, the condition is likely to have an autoimmune paraneoplastic origin. The detection of autoantibodies against the 128-kd antigen in patients with this syndrome should be considered an indication to search for an occult breast cancer. HCV may be the etiologic virus of progressive encephalomyelitis with rigidity; a rare disorder similar to stiff-man syndrome although different because it is progressive and fatal. It is possible that the reported case of association of progressive dementia with concomitant development of stiff-man syndrome in an elderly man represents an exaggerated form of such motor disturbances in dementia, and that clinical and electromyographic features of stiff-man syndrome may be present with increased incidence in patients with dementia.

Which factor interacts with Treslin/TICRR throughout the cell cycle of human cells?

MDM two binding protein (MTBP) is a factor that interacts with Treslin/TICRR throughout the cell cycle. MTBP depletion by means of small interfering RNA inhibits DNA replication by preventing assembly of the CMG (Cdc45-MCM-GINS) holohelicase during origin firing. Although MTBP has been implicated in the function of the p53 tumor suppressor, it is required for DNA replication irrespective of a cell's p53 status. MTBP is proposed to act with Treslin/TICRR to integrate signals from cell cycle and DNA damage response pathways to control the initiation of DNA replication in human cells.

In which genomic regions are Alu enriched?

There are regions such as the four homeobox gene clusters, which are nearly devoid of these repeats that contrast with repeat dense regions in other transcriptionally active regions of the genome. Alu elements are more clustered in genes which are involved in metabolism, transport, and signaling processes. In contrast, they are significantly fewer in genes coding for information pathway components as well as structural proteins. This bias in Alu distribution is independent of the effect of Alu density of the flanking genomic region and is also not affected by the GC content of the gene and its upstream and downstream regions.

Define pseudotumor cerebri. How is it treated?

Benign intracranial hypertension (BIH) is characterized by an elevation of the intracranial pressure not associated with an intracranial process or hydrocephaly, and with normal cerebrospinal fluid (CSF) contents. The elevation of the intracranial pressure is isolated; therefore, diseases such as cerebral venous thrombosis or dural fistulas should not be considered as etiologies of BIH. The exact definition of BIH remains debated, and other terms such as "pseudotumor cerebri" or "idiopathic intracranial hypertension" are often used in the literature. The management of patients with BIH depends mainly on the presence and severity of ocular symptoms and signs on which the prognostic of the disease is based. Repeated lumbar punctures associated with acetazolamide and weight loss are usually efficient enough. However a surgical treatment (optic nerve sheath fenestration or lumboperitoneal shunt) is required when appropriate medical management does not prevent progressive alteration of vision (visual loss or visual field defect), or when the patients complains of severe, refractory headaches. Careful follow-up with repeated formal visual field testing may help preventing a devastating visual loss in these patients.

This phenomenon is known as multilocus inherited neoplasia alleles syndrome (MINAS), which has been potentially linked to more severe clinical manifestations.

Which mechanisms underlie adaptive mutagenesis (stationary-phase mutagenesis) in Bacillus subtilis?

Increased transcription levels potentiate adaptive mutagenesis. Central to stationary-phase mutagenesis in B. subtilis is the requirement for Mfd protein (transcription repair coupling factor). The B. subtilis' ability to accumulate chromosomal mutations under conditions of starvation is influenced by cell differentiation and transcriptional derepression, as well as by proteins homologous to transcription and repair factors. Under conditions of nutritional stress, the processing of deaminated bases in B. subtilis may normally occur in an error-prone manner to promote adaptive mutagenesis. A functional RecA protein is not required for adaptive mutagenesis, which seems to be independent of recombination-dependent repair and, in some cases, of the Y DNA polymerases. Oxidative stress-induced DNA damage has been associated with adaptive mutagenesis. The occurrence of such mutations is exacerbated by reactive oxygen species. Starved B. subtilis cells lacking a functional error prevention GO (8-oxo-G) system (composed of YtkD, MutM, and YfhQ) had a dramatic propensity to increase the number of stationary-phase-induced revertants. The MMR (encoded by the mutSL operon) protects B. subtilis from stationary-phase mutations. The MMR modulation of the mutagenic/antimutagenic properties of MutY regulates stationary-phase mutagenesis. Two of the genes that are involved in the regulation of post-exponential phase prokaryotic differentiation, comA and comK, are involved in adaptive mutagenesis. Also, YqjH, a homolog of DinB protein, plays a role in stationary phase mutagenesis.
