The metabolic clearance rate (MCR) of human growth hormone (HGH) was determined by the constant infusion to equilibrium technique utilizing HGH-(125)I. 22 control subjects had a MCR of 229 +/-52 ml/min (mean +/-SD). No difference was evident between sexes, or between various age groups. Patients with acromegaly demonstrated normal MCR's. Moreover, acute elevations of plasma growth hormone conce...
To understand the meaning of the lactate threshold (LT) and to test the hypothesis that endurance training augments lactate kinetics [i.e., rates of appearance and disposal (Ra and Rd, respectively, mg·kg(-1)·min(-1)) and metabolic clearance rate (MCR, ml·kg(-1)·min(-1))], we studied six untrained (UT) and six trained (T) subjects during 60-min exercise bouts at power outputs (PO) eliciting the...
Antimicrobial resistance associated with colistin has emerged as a significant concern worldwide threatening the use of one of the most important antimicrobials for treating human disease. Here, we examined a collection (n = 980) of Avian Pathogenic Escherichia coli (APEC) isolated from poultry with colibacillosis from the US and internationally for the presence of mcr-1 and mcr-2, genes known ...
Methyl-coenzyme M reductase (MCR) from methanogenic archaea catalyzes the terminal step in biological methane synthesis. Using coenzyme B (CoBSH) as the two-electron donor, MCR reduces methyl-coenzyme M (methyl-SCoM) to form methane and the heterodisulfide product, CoBS-SCoM. MCR contains an essential redox active nickel tetrapyrrolic cofactor called coenzyme F430 at its active site, which is a...
Norepinephrine (NE) kinetics were investigated in freely moving (FM) and minimally stressed (MS) rats with the isotope dilution technique. 1) The mean NE spillover rate (NE-SOR) was 79 +/- 6 ng. kg(-1). min(-1), and the mean NE metabolic clearance rate (NE-MCR) 179 +/- 9 ml. kg(-1). min(-1) (n = 31). Thus the NE kinetics in FM and MS rats are much faster than in human beings, probably related t...
درفصل اول درباره اهمیت تجزیه الکتروشیمیایی وهمچنین درباره خصوصیات کربن ونانومواد کربنی ،روشهای سنتز وکاربرد آنها به عنوان الکترود واصلاح کننده مورد بحث قرار گرفت است. در فصل دوم رفتار اکسایشی داروهای تریامترن و هیدروکلروتیازید را با استفاده از الکترود کربن شیشه ای اصلاح شده توسط نانومواد کربنی بررسی و هر دو دارو را به شکل همزمان در نمونه های قرص و ادرار اندازه گیری شد.اصلاح کننده از ترکیب نانو...
Background and objectives: Calamus rotang is used in traditional medicine. Regarding the previous phytochemical screening of methanol extract of Calamus rotang L. fruits (MCR), this study was performed to find out the antidiarrheal and hypoglycemic effects of the experimented extract in rodents. Methods: Castor oil induced diarrheal test...
During 2006 to 2009, two sediment tracer studies were implemented at the mouth of the Columbia River (MCR) to improve our understanding of littoral sediment transport pathways along the ocean margins of the inlet. Science-based data from these tracer studies is being integrated with other analysis methods to evaluate if dredged material can be preferentially placed within the coastal near shore...
The polymixin colistin is a "last line" antibiotic against extensively-resistant Gram-negative bacteria. Recently, the mcr-1 gene was identified as a plasmid-mediated resistance mechanism in human and animal Enterobacteriaceae, with a wide geographical distribution and many producer strains resistant to multiple other antibiotics. mcr-1 encodes a membrane-bound enzyme catalysing phosphoethanola...
