Gaucher's disease is a lysosomal storage disease caused by a deficiency in the enzyme glucocerebrosidase. A small, heat-stable glycoprotein first obtained from Gaucher spleen (Ho, M. W., and O'Brien, J. S. (1971) Proc. Natl. Acad. Sci. U. S.A. 68, 2810-2813) has been observed to stimulate the activity of glucocerebrosidase isolated from normal tissue. It has been suggested that this material mi...
از آنجا که دانه ی گیاه خرفه منبع غنی ای از اسید های چرب ضروری میباشد لذا نیازمند روشی کارامد جهت استخراج بهینه این اسیدهای چرب میباشیم.با توجه به مزایای روش استخراج با سیال فوق بحرانی شامل سرعت استخراج,گزینش پذیری و کنترل حلالیت,اثر پیش تغلیظ کنندگی, کمی بودن استخراج,تمیزی و ایمنی, دمای پایین ,سادگی ,صرفه جویی در هزینه و قابلیت ادغام با تکنیک های دیگراین روش جدید استخراج برای استخراج اسیدهای چر...
Industrial activities in modern times that are growing rapidly can cause environmental problems. This is due to the increasing amount of waste generated increased production. Untreated dye inhibit sunlight penetration, photosynthesis activity, and growth aquatic biota. One wastes often found methylene blue. Processing blue use a practical adsorption method, easy do at low cost. study showed res...
چکیده در این پایان نامه، در ابتدا از واکنش بین پالادیم استات و آلیزارین زرد gg کمپلکس دو هسته ای ارتوپالادیت [pd{? 2(c,n) -{5-(3-nitrophenylazo) salicylic acid}}(µ-oac)]2 (1) ستنز شد. از واکنش این کمپلکس دو هسته ای ارتوپالادیت (1) با لیگاند های تک دندانه تری فنیل فسفین (pph3)، 6،4،2-تری متیل-پیریدین(me3py) کمپلکس های تک هسته ای (2)، (3) سنتز شدند. همچنین از واکنش بین پالادیم استات و آلیزارین ز...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
INTRODUCTION There is support for the role of gamma aminobutyric acid (GABA) in the etiology of mood disorders. Recent research has shown that hepatocyte growth factor (HGF) modulates GABAergic inhibition and seizure susceptibility. This study was designed to determine and correlate plasma levels of HGF and GABA as well as symptom severity in individuals with obsessive-compulsive disorder (OCD)...
The structural events taking place during the reaction between PAI-1 (plasminogen-activator inhibitor 1) and the plasminogen activators sc-tPA (single-chain tissue plasminogen activator) and tc-tPA (two-chain tissue plasminogen activator) were studied. Complexes were formed by mixing sc-tPA or tc-tPA with PAI-1 in slight excess (on an activity basis). The complexes were purified from excess PAI...
IL-17 is a T cell-derived proinflammatory cytokine in experimental arthritis and is a stimulator of osteoclastogenesis in vitro. In this study, we report the effects of IL-17 overexpression (AdIL-17) in the knee joint of type II collagen-immunized mice on bone erosion and synovial receptor activator of NF-kappa B ligand (RANKL)/receptor activator of NF-kappa B/osteoprotegerin (OPG) expression. ...
