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...

– in this paper we consider some (α ,β ) -metrics such as generalized kropina, matsumoto and f (α β )2α = + metrics, and obtain necessary and sufficient conditions for them to be einstein metrics when βis a constant killing form. then we prove with this assumption that the mentioned einstein metrics must beriemannian or ricci flat.

Let α be a coprime automorphism of group G prime order and let P an α-invariant Sylow p-subgroup G. Assume that p∉π(CG(α)). Firstly, we prove is p-nilpotent if only CNG(P)(α) centralizes P. In the case Sz(2r) PSL(2,2r)-free where r=|α|, show p-closed CG(α) normalizes As consequence these two results, obtain G≅P×H for H We also generalization Frobenius p-nilpotency theorem groups admitting autom...
