PURPOSE RPE65 is preferentially expressed in the retinal pigment epithelium (RPE) and is essential for retinal function. The purpose of the study was to develop methods for the expression of the protein, determine the accurate molecular weight of this expressed protein, and quantitate the amount of RPE65 in the bovine RPE. METHODS Human RPE65 was expressed in Sf9 cells using the baculovirus s...

The purpose of this study is to investigate the interaction of Etofylline as an established drug for asthma remedy, with the major transport protein in human blood circulation, the human serum albumin (HSA). In this respect, the fluorescence and circular dichroism (CD) spectroscopy techniques, along with the molecular docking and molecular dynamics simulation methods were employed. Analysis of ...

It has been documented that specific follicular fluid (FF) biochemical characteristics may be essential to determining oocyte quality. Lipid derivatives have most important role in the fertilization process and embryonic development. MALDI mass spectrometry is used for the diagnosis of biomolecules in the FF and serum of infertile women. FF and blood samples from 13 infertile women (20-38...

the data on the effect of ethylene concentration on polymerization rate for several modifications of modern highly active titanium–magnesium catalysts ticl4/mgcl2 are presented. these catalysts differ in titanium content and conditions of support preparation, activities, and the shape of kinetic curves. it is found that the observed order of polymerization rate with respect to ethylene in the r...

  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 descripti...

esophagus cancer is the eighth most common cancer worldwide and particularly high in an area extending from the southern border of the caspian sea in iran across central asia to china. since information about this mysterious disease is poor, proteomics may be solving this enigma. altering gene expression in cancer cell is a remarkable indicator can be detected by proteomics techniques and bioin...

one of the bio-sensing mechanisms is mechanical. rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. this study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on silicon wafer, with the ...
