background:     objective:     methods:     results:     conclusion:

in this work, we calculated the several physico chemical properties containing of solubility (byvcl), lipophilicity (by milinspiration), dipole and quadrupole moments (by density functionaltheory) for 7 azt analogs, and compared these parameters with inhibition assays of them. it isresulted; cytotoxicity of these drugs is related with their lipophilicity inversely. with using of thisresult, for...

the aim of this research was to survey of using soy protein isolates and tragacanth gum as egg substitutes in mayonnaise formulation. the mayonnaise prepared with difierent compositions of soy protein isolate, egg, and tragacanth by applying the optimal mixture design method and effect of this substitution on its stability, heat stability, viscosity, texture, physicochemical and sensory charact...

an action resulting from an object like human's damaging action can cause liability for those who possess them. the french civil law at its approval time (1804) had not predicted this principle and just in articles 1385, 1386, the liability of damages resulting from two types of objects, i.e. animals and buildings due to imposing great damages by them had been predicted by french law. howe...

background:   objective: we evaluated the icsi outcome in our program for (htlv-1) serodiscordant couples (sdcs) with the female infected in comparison with control group.   materials and methods: this study was performed between 2007 and 2011 in novin infertility treatment center (mashhad, iran). we examined 32 icsi cycles of htlv-1 infected women in comparison with an age matched control grou...

a new kinetic spectrophotometic method for the determination of trace amount chromium (iii) in teareal samples has been described based on it s the catalytic effect on the oxidations of 1 - ( 2 –pyridylazo ) - 2 - naphthol, (pan), by potassium bromated in sulfuric acid. the reaction is followedspec- trophotometrically by measuring the decrease in the absorbance at 469 nm. under the optimumcondi...

a new facile route for synthesis of 3- (aryl) -8, 9- di (alkyl) thieno [3,2-e] [1,2,4] triazolo pyrimidines derivative from the same starting material, 2- amino - 4,5 -di (alkyl) thiophene-3- carboxamide, has been developed through heterocyclization of the corresponding arylidene-hydrazino -5,6 -di (alkyl) thieno [2,3-d] pyrimidine under refluxing condition with acetic anhydride followed by air...

normal 0 false false false en-us x-none ar-sa background: alzheimer's disease (ad) is a progressive neurodegenerative disease in which endothelial cell (ec) can be affected. in brain, functional changes in ecs contribute to reductions in resting blood flow. furthermore, angiotensin-converting enzyme inhibitors (ace-i) have beneficial effects on endothelial dysfunction. this is the first study t...
