Introduction: Renal ischemia/reperfusion (I/R) injury due to reactive oxygen species (ROS) formation is the main cause of acute kidney damage. Nitric oxide (NO) biosynthesis and oxidative stress are closely related to the pathogenesis of renal I/R injury. This study was undertaken to determine the effects of L-arginine (L-arg) as NO donor and aerobic exercise (EX) and also the combination of L-...

background: to evaluate the effect of exendine-4 (ex-4), a glucagon-like peptide 1 (glp-1) receptor agonist, on the differentiation of insulin-secreting cells (ipcs) from rat adipose-derived mesenchymal stem cells(admscs). materials and methods: in this experimental study, admscs were isolated from rat adipose tissue and exposed to induction media with or without ex-4. after induction, the exis...

Institutions, Markets and Men’s and Women’s Wage Inequality: Evidence from Ukraine ∗ Ukraine, the second largest country in the former Soviet bloc, is facing the challenge of rallying popular support for major structural reforms.

It ...

on the complex upper half-plane H, provably invariant under the linear fractional action of SL2(R), but it is oppressive to verify this directly. Worse, the goal is not merely to verify an expression presented as a deus ex machina, but, rather to systematically generate suitable expressions. An important part of this intention is understanding reasons for the existence of invariant operators, a...

The aim of this paper is to analyse the political, social and economic background of the divergence of Belarusian and Ukrainian transitions. We focus on Belarus in order to find explanation for questions such as why could Lukashenko remain the authoritarian leader of Belarus, while in Ukraine the position of the political elite had proved less stable and collapsed in 2004. On the theoretical fr...

These are but a few of the major problems the author had to tackle in writing this book, and he does justice to both sides of the arguments with unrelenting impartiality. The volume obviously is a survey-book for the non-professional public, nevertheless one would still prefer to have some of the author's own opinions instead of sweeping and often contradictory generalizations in an almost epig...

a reliable method is described for rapid proliferation of axillary shoots from nodal segment of mature field-grown aromatic and medicinal plant vitex negundo through in vitro culture. of different concentrations of n6-benzyladenine (ba) evaluated as supplements to murahige and skoog (ms) medium, ba at 1mg/l was effective in enhancing bud break and shoot regeneration. response of explants was al...

in this study, the neutral monosaccharide composition of the extracellular polysaccharide (eps), extracted from thermal bacillus, was determined by liquid chromatography-mass spectrometry and high performance liquid chromatography. our analysis indicated that the eps consisted of rhamnose, mannose, galactose, glucose, fructose, arabinose and xylose. in addition to the neutral sugars in the eps,...
