background: the purity and correct folding of a recombinant protein is critical for any structural, biochemical and vaccine design studies. plasmodium vivax duffy binding protein-ii is a leading vaccine candidate for vivax malaria. in the present study, the purification process of recombinant dbp-ix (a variant form of pvdbp-ii) was optimized to achieve the highest yield and purity. moreover, na...

objective(s): a fast and reliable evaluation of the binding energy from a single conformation of a molecular complex is an important practical task. artificial neural networks (anns) are strong tools for predicting nonlinear functions which are used in this paper to predict binding energy. we proposed a structure that obtains binding energy using physicochemical molecular descriptions of the se...

background:   objective: this study was conducted to determine the effect of omega-3 supplementation on sex hormone-binding protein (shbg), testosterone, free androgen index (fai) and menstrual status in women with pcos.   materials and methods: this double-blind randomized clinical trial was conducted on 78 overweight/obese women with pcos. participants were randomized to receive omega-3 (3gr/...

Human serum albumin (HSA) is the most abundant protein in the blood plasma. Drug binding to HSA is crucial to study the absorption, distribution, metabolism, efficiency and bioavailability of drug molecules. In this study, isothermal titration calorimetry and molecular dynamics simulation of HSA and its complex with indometacin (IM) were performed to investigate thermodynamics parameters and th...

in this study at first , an azo dye, 2,7- naphthalenediol, 2-[(4-bromophenyl)azo (bpand) as a ligand has been synthesized by addition of p-bromoaniline to the modified montomorillonite k10 clay. this ligand was characterized using 1h-nmr, uv-vis and ir spectroscopies. subsequently, its interaction with calf thymus deoxyribonucleicacid ,ct-dna was investigated in 5 mm phosphate buffer solution, ...

in this study, binding ability of lactobacillus rhamnosus lgg to aflatoxin of pistachio was investigated. results indicate that the bacterium has aflatoxin surface binding ability of 35% (with initial concentration of 10 ppb aflatoxin) in exponential phase. acid and heat treatment increase this ability to 85%. in the second concentration of aflatoxin (20 ppb), this binding ability for viable ce...

In the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (BSA) have been analyzed on basis of intrinsic thermodynamic quantities. In this regards, the intrinsic Gibbs free energy of binding, AGb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...
