antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical-induced oxidative stress. a variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. this article describes a test method for screening the antioxidant activity of 60 iranian plants o...

The Wiener index of a graph Gis defined as W(G) =1/2[Sum(d(i,j)] over all pair of elements of V(G), where V (G) is the set of vertices of G and d(i, j) is the distance between vertices i and j. In this paper, we give an algorithm by GAP program that can be compute the Wiener index for any graph also we compute the Wiener index of HAC5C7[p, q] and HAC5C6C7[p, q] nanotubes by this program.

1,3-dipolar cycloaddition reaction of 1 mol or 2 mol of dibenzalaceton with 1 mol of non-stabilized azomethinylides generated in situ by decarboxylative condensation of isatin and proline or sarcosine give the novel new spiro-oxindolo(pyrrolizidines/ pyrrolidines) instead of bis-spirooxindolo( pyrrolizidines/ pyrrolidines).

the variants of angiotensin converting enzyme (ace) and matrix metalloproteinases (mmps) genes might be involved in the pathogenesis of end stage renal disease (esrd) and hypertension. we studied the ace insertion/deletion (i/d) and mmp-7 a-181g variants in 99 unrelated esrd patients and 117 individuals without renal complications from western iran with kurdish ethnic background. the frequency ...

We introduce the notion of squeezing function corresponding to $d$-balanced domains motivated by concept generalized given Rong and Yang. In this work we study some its properties relation with Fridman invariant.

The kinetics and mechanisms of the substitution reactions of trans-[Co(en)2CNCl]+ with unidentate anions,  , CN¯, I¯,  , Br¯ and SCN¯ in 60% v/v DMF-H2O binary solvent at 40.0±0.2 °C were studied spectrophotometrically. An Id mechanism was assigned for the replacement of chlorine by , CN¯ and I¯, an Ia one for...
