(Wiley, 2014)Serotonin (5-HT) production and expression of 5-HT receptors (5-HTRs) occur early during prenatal development. Recent evidence suggests that, in addition to its classical role as a neurotransmitter, 5-HT regulates neuronal ...
-
(ELSEVIER, 2008-07)Increased serum uric acid has been identified as an independent risk factor for cardiovascular disease. However, because of its antioxidant capacity, uric acid may play a beneficial role in endothelial function. This ...
-
(Public Library Science, 2016)Background Paper mulberry (Broussonetia papyrifera (L.) L'Her. ex Vent) is a dioecious tree native to East Asia and mainland Southeast-Asia, introduced prehistorically to Polynesia as a source of bark fiber by ...
-
(Oxford University Press, 2017-05)With increased life expectancy, women will spend over three decades of life postmenopause. The menopausal transition increases susceptibility to metabolic diseases such as obesity, diabetes, cardiovascular disease, and ...
-
(1980)Sex-related variations in the clinical effects of drugs may be observed. In an intensive prospective drug surveillance study of 1920 patients hospitalized at the Department of Medicine of the J.J. Aguirre Hospital in ...
-
(Wiley-Blackwell, 2016)The aim of this study was to evaluate quinoa protein (Q), chitosan (CH) and sunflower oil (SO) as edible film material as well as the influence of this coating in extending the shelf-life of fresh blueberries stored at 4 ...
-
(KLUWER ACADEMIC PUBL, 1998-07)Penicillium purpurogenum was mutated with u.v. light to increase xylanase production. The best mutant, UV-64, was treated with N-methyl-N'-nitro-N-nitrosoguanidine and a second generation of mutants was obtained (NG-188 ...
-
(2011)We report on the results of X-ray investigations in two series of polymer monomer composites, PM6Rm-33 and PMnR12-33, which consist of mixtures of achiral liquid crystalline side chain polymers and their monomers. These ...
-
(2006)Silver nanowire arrays with high aspect ratios have been prepared using potentiostatic electrodeposition within the confined nanochannels of a commercial porous anodic aluminium oxide template. The nucleation and growth ...
-
(1989)Acetaminophen hepatotoxicity is characterized by glutathione depletion, cellular necrosis, and, in some instances, by the induction of lipid peroxidation. Silybin dihemisuccinate, a soluble form of the flavonoid silymarin, ...
-
(1983)A simple and rapid method for the multielement routine analysis of atmospheric particulate matter is described. The samples collected on four different types of filters were treated with HNO3 and HCl at 110-120 °C in pyrex ...
-
(ELSEVIER SCIENCE BV, 2002-12-05)This work presents a simple and fast method for the simultaneous determination of amiloride and furosemide by digital derivative spectrophotometry. HCl 1 x 10(-2) mol/l dissolved in ethanol was used as solvent and to extract ...
-
Simultaneous determination of ascorbic acid and acetylsalicylic acid in pharmaceutical formulations (AOAC INTERNATIONAL, 2001-02)A direct, simple, and practical first-derivative spectrophotometric method is described for simultaneous determination of ascorbic acid and acetylsalicylic acid. The effects of the solvent, excipients, and spectral variables ...
-
(1999)A direct and simple first derivative spectrophotometric method has been developed for the simultaneous determination of clidinium bromide and chlordiazepoxide in pharmaceutical formulations. Acetonitrile was used as solvent ...
-
(1995)A simple, sensitive and selective first derivative spectrophotometric method has been developed for the determination of copper and iron in mixtures. The method is based on the recovery of the analytes, by liquid-liquid ...
-
(AOAC INTERNATIONAL, 2003-03)A simple and fast method was developed for the simultaneous determination of dapsone and pyrimethamine by first-order digital derivative spectrophotometry. Acetonitrile was used as a solvent to extract the drugs from the ...
-
(AOAC INTERNATIONAL, 2002-07)This paper reports a simple and fast method for the simultaneous determination of estradiol (ED) and medroxyprogesterone acetate (MP) in pharmaceutical formulations by second-derivative spectrophotometry. Methanol was used ...
