In this paper, we study the notion of solvable $L$-subgroup of an $L$-group and provide its level subset characterization and this justifies the suitability of this extension. Throughout this work, we have used normality of an $L$-subgroup of an $L$-group in the sense of Wu rather than Liu.
One of the major issues in aquaculture is to keep balance between growth rate of fish and optimal use of consumed food. L-carnitine is considered an effective food supplement for fish growth. Sobaity seabream is one of the commercially important species in the Persian Gulf that is highly considered in aquaculture too. Growth indices and survival rate of 240 Sobaity fingerlings with mean weight ...
Abstract Background and Objectives: Fluoride is one of the anions existed in water and soil. Its amount is not the same in different kind of water. Since the most of body's need to fluoride should be provided by drinking water, this study was aimed at determining the fluoride level in water supply of Gorgan rural regions. Materials and Methods: In this Cross-Sectional study, the subjects were a...
Background: The assessment of altered nitric oxide (NO) availability is of potentially important diagnostic and prognostic significance. The present study is aimed to investigate the effect of L-arginine (as a natural NO donor) supplementation on NO metabolite in a rabbit model of hypercholesterolemia to find a reliable marker for endothelial NO production. Methods: White male rabbits (n = 30)...
Introduction: Homocysteine is an aminoacid yielded from methionin to cysteine metabolism. Normal plasma concentration of homocysteine in human is between 5-15 mol/l and an increase more than 5 mol/l can increase the risk of cardiovascular diseases, atherosclerosis and thrombosis. On the other hand in dialysis patients due to some reasons such as uremia, genetic factors, dialysis related factors...
purpose: to evaluate total plasma homocysteine level during the acute phase of central retinal vein occlusion (crvo) compared with a matched healthy group in iranian population, and determine whether hyperhomocysteinemia is also a risk factor for crvo. methods: a study group contains 54 patients presenting with crvo in recent one month, acute phase of the decease, was compared for fasting total...
