, Shaheed Beheshti University of Medical Sciences Abstract: Background: The main surgical side effects and complications in many cases are due to the long duration of the anesthesia. Obviously these phenomena are related to the use of anesthetic drugs which have effects on liver blood flow, immune system and homeostasis. One important effect is activation of complement system. In this stud...
objective(s): the rotavirus nonstructural protein 4 (nsp4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase c-dependent and phospholipase c-independent pathways in infected cells. it is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...
background: quality in health care can be seen as having three principal dimensions: service, technical and customer quality. this study aimed to measure customer quality in relation to self-management of type 2 diabetes. methods: a cross-sectional survey of 577 type 2 diabetes people was carried out in australia. the 13-item patient activation measure was used to evaluate customer quality base...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
هدف از انجام این پژوهش مطالعه ی اثر عملیات حرارتی نیمه جامد و equal channel angular pressing(ecap) بر ساختار و خواص مکانیکی آلیاژ al-fe-si به منظورایجاد یک ساختار بهینه با خواص مناسب می باشد. برای کروی کردن دانه ها و افزایش چقرمگی در نمونه، نیاز به انجام عملیات حرارتی نیمه جامد در دما های بین دمای ذوب و انجماد برای مدت زمان های مشخص نگهداری در کوره است. پیش فرض شروع کروی شدن در این فرایند، که ب...
The efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. Conclusions were drawn regarding selection of solid phase according to pore size, rigidity, pH stability, Chemistry of derivation and activation, and gross concentration of immobilized ligand require...

Objectives: The present study was carried out in order to validate the Persian version of Behavioral Activation for Depression Scale (BADS) the students population. Method: 370 students of Tehran and Meshed’s (in North-East of Tehran) Ferdowsi Universities completed BADS and Depression Anxiety Stress Scale (DASS). Confirmatory factor analysis was used to assess validity. Also, Pearson correlat...
A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...
In this research, a mineral barite powder was reduced by carbon monoxide gas and the effects of reduction time and temperature was investigated as well as barite particle size. Results showed that the best result would be feasible when the barite particle sizes are between (-70 +100) in mesh scale. The barite reduction could reach the maximum level (98%) after reduction by carbon monoxide at 85...
