objective(s):to investigate the effects of local mild hypothermia on the expression of fas, fasl and mmp-3 after cerebral ischemia-reperfusion in rats. materials and methods:male wistar rats were divided into sham-operated group (sham), normothermia group (nt), and hypothermia group (ht). mcao/r model was established by longa’s method, and reperfusion was allowed after 2 hr occlusion. mild hypo...

newly  identified  t  helper  cell  22  (th22)  is  a  subset  of  cd4+t  cells  with  specific properties apart from other known cd4+ t cell subsets with distinguished gene expression and function. th22 cells are characterized by production of a distinct profile of effector cytokines, including interleukin (il)-22, il-13, and tumor necrosis factor-α (tnf-α). the levels of th22 and related cyto...

music consumption is a new topic in the academic literature, but the consumption of music itself has been part of human culture for centuries and all human more or less listen to it in order to fill their leisure time. marketers always find it challenging to identify the best way for selling music which at the same time can be accepted by different consumers, too. so, we tried to investigate th...

endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. soluble forms of these molecules can be detected in plasma, and their concentrations are thought to reflect the degree of activation of a particular cell type. the aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (svcam...

introduction: interleukin-2 (il-2) as a t helper type 1 (th1) cytokine has an important role background and objective: interleukin-2 (il-2) as a t helper type 1 (th1) cytokine has an important role in activation, growth and differentiation of several immune cells. moreover il-2 is known as a pro-inflammatory and anti-tumoral cytokine. in addition deysregulation of il-2 in some diseases such as ...

conclusions moderate exercise for 8 weeks increased the ifn-γ and decreased the il-17 serum levels in the morphine-dependent rats. for this reason, this type of exercise can improve the function of the immune system during morphine withdrawal syndrome. results after 8 weeks of exercise, a significant increase was observed in the serum ifn-γ level in the ht group (251.17 ± 13.045) in comparison ...

mcm-41 is one of the groups of mesoporous materials that have wide applications as adsorbents, ion exchangers and catalyst supports. in this work spherical and rod-like mcm-41s were synthesized in homogeneous and heterogeneous reaction media, respectively. for synthesis of these materials the cationic surfactant cetyltrimethylammonium bromide (ctmabr) was used as template and tetraethylorthosil...

nitrogen forms exert significant effects on physiological and morphological characteristics of plant. in this study, the effects of ammonium, nitrate, and ammonium-nitrate on pepper plants were investigated in soil culture, as well as in solution culture. in the soil culture, 3, 4-dimethylpyrazole phosphate (dmpp) was used as a standard nitrification inhibitor to guarantee the presence of ammon...
