Raltegravir is a potent human immunodeficiency virus 1 (HIV-1) integrase strand transfer inhibitor that is being developed as a novel anti-AIDS drug. The absorption, metabolism, and excretion of raltegravir were studied in healthy volunteers after a single oral dose of 200 mg (200 microCi) of [(14)C]raltegravir. Plasma, urine, and fecal samples were collected at specified intervals up to 240 h ...
Introduction: Pheromones play a great role in the reproductive and social behavior of animals. The main sources of pheromones are urine and paracrine secretions. Through the neuroendocrine system, prolactin is a safe parameter to measure and compare the effects of pheromones on the sexual, maternal and also lactating behavior. Methods: Female rats were divided into 19 groups (n=8). To measur...
TGF-beta and oxidant stress have been considered to play key roles in the pathogenesis of diabetic vascular complications; however, the stimulus for these factors in humans is not clear. The purpose of this in vivo study was to determine whether transient hyperglycemia in humans is sufficient to increase renal production of TGF-beta1 and urinary isoprostanes in normal humans. A hyperglycemic cl...
The purpose of this study was to measure ambient lead concentrations in Tehran's 12th Municipal District and also Pb concentrations in urine samples from municipal workers assigned to the same region. In this research workers from the 12th District were matched and compared with a control group who were doing the same type of work in another region in northern Tehran with lighter traffic and co...
introduction: hydrogen fluoride is one of the materials which is widely used in making glass, cleaning silicon, manufacturing florescent lamps, ceramics and also in separating uranium isotopes. on the other hand, exposure to this substance could cause health problems including eye, nose, throat and mucus membranes irritation. this study examines the relationship between fluoride (f) in the uri...
Improvements in methodologies for measuring concentrations of catecholamines (CA) have led to an increasing use of these compounds as markers in the screening of patients and in long-term clinical trials. Because of the associated logistical problems, we have investigated the unresolved question of optimal conditions for sample preparation and for storage of plasma and urine samples. Results sh...
Abstract Background and objectives: Ureaplasma urealyticum is one of the most important causes of Nongonococcal urethritis (NGU) and non-specific urethritis (NSU) in men. Also Mycoplasma hominis has a role in causing NGU and NSU. The aim of this study was the detection of Mycoplasma hominis & Ureaplasma urealyticum in men suffering from NGU and NSU by prostatic massage method and first- void Ur...
objective(s): the object of the study is to examine the effects of δ9-tetrahydrocannabinol (thc) against oxidative stress in the blood and excretion of thc metabolites in urine of type 2 diabetic rats. materials and methods: the control (n=8), thc control (n=6), diabetes (n=8) and diabetes + thc (n=7) groups were created. type 2 diabetes was induced by nicotinamide (na, 85 mg/kg) + streptozotoc...
Epidemiological studies suggest that a moderate consumption of anthocyanins may be associated with protection against coronary heart disease. The main dietary sources of anthocyanins include red-coloured fruits and red wine. Although dietary anthocyanins comprise a diverse mixture of molecules, little is known how structural diversity relates to their bioavailability and biological function. Th...
