introduction: ischemia leads to loss of neurons by apoptosis in specific brain regions, especially in the hippocampus. the purpose of this study was investigating the effects of exercise preconditioning on expression of bax, bcl-2, and caspase-3 proteins in hippocampal ca1 neurons after induction of cerebral ischemia. methods: male rats weighing 260-300 g were randomly allocated into three grou...

objective(s):solid dispersion formulation is the most promising strategy to improve oral bioavailability of poorly water soluble drugs. the aim of this study was to compare the effect of polyvinylpyrrolidone k30 (pvp) and poloxamer-188 (plx) as carrier in solid dispersion formulations of celecoxib (clx). materials and methods: solid dispersions of clx:pvp or clx:plx were prepared at different r...

background: this study was designed to evaluate whether or not t. gondii and its derivatives can change the gene expression level of il-10 in murine leukocytes in vivo.   methods: fifty balb/c mice were divided into 5 groups, four of which received the excretory/secretory product (esp) from cell culture medium, the esp from cell free medium, the toxoplasma lysate product (tlp) and the active ta...

objective: obesity increases production of the extracellular matrix (ecm) role in pathological cardiovascular damage. regular exercise and the use of medicinal plants, particularly celery, in damage to be effective. the aim of this study is to investigate the changes in matrix metalloproteinases 2,9 (mmp 2,9) and tissue inhibitor of matrix metalloproteinase 1 (timp-1) with synchronized exercise...

background: the association between lipid peroxidation biomarkers and adipocytokines is hypothesized in preeclampsia but little is known about it. objective: the present study was undertaken to determine the association of lipid peroxidation biomarkers measured by the levels of 8-isoprostane and malondialdehyde with adipocytokines leptin and adiponectin in maternal serum of preeclamptic women. ...

an efficient, one-pot, four-component procedure for the synthesis of a small library of new chiral spiro- oxindolopyrrolidines with high regio-, diastereo- (>99:1 dr), and enantioselectivity (up to 80% ee) is described. in this process, the regio- and stereochemical 1,3-dipolar cycloaddition of azomethine ylides, which were generated insitu by the reaction of isatin derivatives and sarcosin,wit...

cu(ii) complex with l-histidine (his) ligand, immobilized within al-mcm-41, designated as cu(his)2/al-mcm-41 was prepared and characterized by powder x-ray diffraction (xrd), nitrogen adsorption desorption, ftir, uv-vis and chemical analysis techniques. the surface area and pore volume were found to decrease after immobilization of cu(ii) complex on al-mcm-41. it was found that cu(his)2/al-mcm-...

background: it has been previously demonstrated that her-2 (human epidermal growth factor receptor 2) positive breast cancers are associated with an aggressive nature. villin is an actin bundling protein that plays a key role in actin reorganization and cell remodeling during stress. in this study, we aimed to investigate the correlation of villin gene expression with her-2 in breast cancer pat...
