objective: to investigate the association of c631t single nucleotide polymorphisms in spo11 gene with male infertilityfollowed by an in silico approach. spo11 is a gene involved in meiosis and spermatogenesis process, which in humans, this gene is located on chromosome 20 (20q13.2-13.3) with 13 exons. materials and methods: in a case-control study, 200 blood samples were collected from the ivf ...

A set of Xanthohumol derivatives were selected and molecular docking studies of these ‎compounds on thioredoxin reductase were conducted. Based on new structural patterns using in ‎silico-screening study, new potent lead compounds were designed. The results due to validated ‎docking protocols lead to find that Thr58, Gly57, Gly21, Asp334, Glu163, Ala130, IIe332, ‎Val44 and Gly132 are the main a...

efficiency of enzymes which are used in industrial or environmental applications is highly dependent on their thermal stability. in this study, the stability of dfpase has been evaluated after introducing disulfide bonds to the structure. the results obtained from a series of protein design software were subjected to molecular dynamics simulation at different temperature to test the performance...

The biopharmaceutical profile of a compound depends directly on the dissociation constants of its acidic and basic groups, commonly expressed as the negative decadic logarithm pKa of the acid dissociation constant (Ka). The acid dissociation constant (also protonation or ionization constant) Ka is an equilibrium constant defined as the ratio of the protonated and the deprotonated form of a comp...

A review on applicability of in silico methods for toxicity testing by calculation for regulatory purposes, their survey and background of QSAR (Quantitative Structure-Activity Relationships) analysis are presented.
