Jacobson's generalization [5, Theorem 8] of Wedderburn's theorem [8] states that an algebraic division algebra over a finite field is commutative. These algebras have the property that some power2 of each element lies in the center. Kaplansky observed in [7] that any division ring, or, more generally, any semisimple ring, in which some power of each element lies in the center is commutative. Ka...

background: thymus daenensis celak. is one of the medicinal plants which cultivated in iran. this plant involve high amount of polyphenols including thymol and carvacrol, which were reported to possess the high antioxidant activity. objective: antioxidative activity (aoa) and chemical constituents of thymus daenensis essential oil (tdeo) were examined. also, the effect of thermal treatments (80...

the radioprotective effects of vitamin c and famotidine were investigated using the micronucleus test for anticlastogenic and cell proliferation activity. various doses of vitamin c and famotidine were administered intraperitoneally 2 h before 2gy gamma irradiation to nmri adult male mice. frequency of micronuclei in 1000 pces (mnpces) were scored for each sample. cell proliferation ratio (pce/...

The aim of this paper is to investigate generalizations locally artinian supplemented modules in module theory, namely radical and strongly modules. We have obtained elementary features for them. Also, we characterized by left perfect rings. Finally, proved that the reduced part a $R$-module has same property over Dedekind domain $R$.

Factors such as oxidative stress and reduced acetylcholine level have been implicated in Alzheimer’s disease (AD) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. Centaurea is a genus with about 500 species world wild, many of them have shown to possess bio...

Abstract The class of abelian p -groups with minimal full inertia, that is, satisfying the property fully inert subgroups are commensurable invariant is investigated, as well groups not this property; it known both direct sums cyclic and torsion-complete first type. It proved “small" endomorphism ring do satisfy concrete examples them provided via Corner’s realization theorems. Closure properti...

Free radicals are implicated for many diseases including diabetes mellitus, arthritis, cancer, ageing. etc. In the treatment of these diseases, antioxidant therapy has gained utmost importance. Alcoholic extract of Medicago sativa was studied for its in vitro antioxidant activity using different models viz. DPPH radical scavenging, ABTS radical scavenging, iron chelating activity, lipid peroxid...

Thirteen polyphenolics were isolated from fresh pods of Caesalpinia pulcherrima using various methods of column chromatography. The structures of these polyphenolics were elucidated as gallic acid (1), methyl gallate (2), 6-O-galloyl-d-glucoside (3), methyl 6-O-galloyl-β-d-glucoside (4), methyl 3,6-di-O-galloyl-α-d-glucopyranoside (5), gentisic acid 5-O-α-d-(6'-O-galloyl)glucopyranoside (6), gu...
