(1985)1. 1. Liver microsomes from alloxan diabetic rats displayed decreased activity to hydroxylate testosterone only at the 2-α and 6-β positions. 2. 2. Diabetic insulin-treated rats showed higher hydroxylase activities than ...
-
(Birkhäuser-Verlag, 1986)We have observed a differential effect of silybin dihemisuccinate on rat liver microsonal oxygen consumption and on lipid peroxidation induced by NADPH-Fe2+-ADP and t-butyl hydroperoxide. These results are ascribed to the ...

(1986)Human fetal hemoglobin assayed in a peroxidizing system shows an increased prooxidative effect when compared to human adult hemoglobin. This effect is related only to the oxyhemoglobin form since both fetal and adult ...
-
(2012)A new withanolid amine was isolated from Dunalia spinosa (Solanaceae). Its relative stereochemistry was determined using FT-IR, 1H and 13C NMR spectroscopies and high resolution mass spectrometry. Nicotine was also isolated; ...
-
(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 ...
-
(1983)Exposure of Xenopus laevis oocytes to temperatures above 31° causes a drastic decrease in protein synthesis and a relative increase of a heat shock protein (HSP) of approximate molecular weight of 68,000. A significant ...
-
(1983)Kainate (0.62-5 mM) was found to increase the initial rate of influx of 45Ca and of 22Na into the non-inulin space of rat thin brain cortex slices incubated in vitro, and to shorten the equilibration time for both these ...
-
(1983)As part of study of Chagasic cardiopathy in Chile we report a follow-up study of 100 cardiopathic patients from two endemic areas who had been diagnosed 4 years earlier during an epidemiological and clinical survey. The ...
-
(1983)The effects of angiotensin II on efflux of radiocalcium and production of aldosterone from dispersed bovine adrenal glomerulosa cells were studied using a flow-through system. Concentrations of angiotensin II between 1.25 ...
-
(1982)The electroactivity of a degradation product from penicillin V is described.This electroactive product is formed by acidic hydrolysis at pH 4.0 and heating at 90QC for 60 minutes. This derivative has not been identified, ...
-
Cyclic voltammetry and digital simulation of the electroreduction of ortho- and meta-nitro aryl ... (1999)Cyclic voltammetry (CV) and digital simulation methods are utilized to elucidate the mechanism of electrochemical reduction of a series of nitro aryl 1,4-dihydropyridines in protic (aqueous) and mixed media. The experimental ...
-
(1984)The isolation and identification of a cathodic degradation product from cephradine after acidic hydrolysis in presence of 1 % formaldehyde is reported. Also, the electroacti vity of an anodic degradation product is described. ...
-
(Kluwer Academic Publishers, 1983)Based on a similarity ring constructed from a substitution probability matrix, we have analyzed the conservation of some amino acid properties in the evolution of proteins. Refractive index and bulkiness are highly conserved, ...
-
(1976)The effect of tachycardia on the distribution of coronary blood flow was studied in the dog heart using the radioactive microsphere technique. Increasing heart rate from 1.7 to 3.0 Hz produced an increment of flow to the ...
-
(1975)The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing them independently ...
-
(2010)The International Collaboration to Sequence the Atlantic Salmon Genome (ICSASG) will produce a genome sequence that identifies and physically maps all genes in the Atlantic salmon genome and acts as a reference sequence ...
