in an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (pocl3). the synthesized compounds were identified by 1h-nmr, 13c-nmr, ft-ir spectroscopic techniques and elemental analysis. all products were...

in this paper by using the notiαon of anti fuzzy points and its besideness to andnon-quasi-coincidence with a fuzzy set the concepts of an anti fuzzy subalgebrasin bm-algebras are generalized and their inter-relations and related propertiesare investigated.

α-amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2zncl2 as a bio lewis acidic ionic liquid. mild lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.

the quality traits of triticum dicoccoides ku-13441 (triticum turgidum l. var. dicoccoides (aabb, 2n= 4x= 28)) were analyzed by mixograph, and the results showed that t. dicoccoides ku-13441 had desirable qualities in gluten strength and flour stirring tolerance. subsequently, seventeen novel full-orf α-gliadin genes and thirty-five pseudogenes were cloned and sequenced from t. dicoccoides ku-1...

background and objectives:wild sage(salvia macrosiphon boiss.) known as “marvak” in persian is one of the polymorphic and abundant plants of lamiaceae. the plants whole seeds usually soaked or boiled in hot water are widely used for inflammatory ailments in folk medicine. documents have shown that there is scant information on the chemical constituents of this plant seeds. the current study was...

conclusions our findings indicate that fenofibrate (ppar-α agonist) is able to prevent dn progression and improve kidney performance during chronic uncontrolled hyperglycemia possibly through increase in no bioavailability of kidney. results fenofibrate did not change the blood glucose of normal or diabetic rats. diabetes increased the proteinuria (82%) and blood creatinine of diabetic rats (4....

in our previous study, we compared the two α-amylase enzymes from bacillus sp.kr8104, bka∆(n44) and bka∆(n44c193) which is the secreted form of it. the results indicated that the presence of 193 amino acids propeptide in the c-terminal of bka∆(n44) changed its enzymatic parameters like an uncompetitive inhibitor in comparison to bka∆(n44c193). in the present study, we cloned the dna sequence of...

polycyclic aromatic hydrocarbons (pahs) are a class of complex substances that are produced during incomplete combustion of fossil fuels. pahs are known to be persistent pollutants which can remain in nature for years. in 1991 during the first persian gulf war south west part of iran was contaminated heavily. this study was undertaken to see if the pahs can be traceable in animal tissues many y...

background: spermatozoa preservation is an approach to improve the fertility rate to pass on the valuable genetic material from sire to their offspring. during the last 20 years, reproductive biotechnologists have focused on the approaches that improve spermatozoa cryosurvival. one of the possible mechanisms is supplementation in semen extender. objectives: the aim of this study was to evaluate...
