(1994)Whole-mounted or sectioned eggs of the glossiphoniid leech Theromyzon rude were studied under the dissecting, fluorescence, light, and electron microscope. The egg is often penetrated by a single sperm that enters the ...
-
(1993)Microsomal lauric acid 12-hydroxy lauric acid (ω)-hydroxylation and fatty acid peroxisomal β-oxidation were studied in kidney tissue from starved rats. Starvation increased the microsomal ω-hydroxylation and peroxisomal ...
-
(1993)1. Liver microsomes from alloxan or streptozotocin diabetic rats displayed differential drug metabolizing abilities in vitro. 2. Only streptozotocin liver microsomes exhibited changes in the cytochrome P-450 normal spectral ...
-
(1994)A nonradioactive method is developed to detect DNA polymerase activity after sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis containing gapped DNA as template. The technique is based on the use of digoxigenin- ...
-
(1993)The cyclic voltammetric behaviour of nifedipine was studied. The addition of three aprotic solvents to nifedipine in an aqueous citrate buffer system was examined. Qualitatively they result in separation of the initial ...
-
(1993)Modification of cardiac β-adrenergic receptors (β-AR), resulting from the stimulation of the sympathetic nervous system, is one of the most important factors in the generation of cardiac hypertrophy and heart failure. In ...
-
(1993)The chronic daily administration of isoproterenol provokes in mouse parotid glands the induction and progressive accumulation of a family of secretory polypeptides named polypeptides C, D, E, F, and G (polypeptides C- G). ...
-
(1993)An investigation of the influence of the aggregate sizes on some elements of an oxisol is presented. Proton Induced X-ray Emission (PIXE) has been used to carry out this analysis. Aggregate sizes from <0.5 mm to 4.7 mm ...
-
(1993)1. 1. The antinociceptive action of calcium channel blockers administered intracerebroventricularly to mice using the acetic acid writhing test was studied. 2. 2. The drugs produced dose-dependent inhibition of the number ...
-
(1993)1. 1. The formalin test and R-III nociceptive electromyographic reflex were used to determine the origin of analgesia induced by ketorolac tromethamine (KT) in rats. 2. 2. The effects of KT and morphine were compared after ...
-
(2001)The structural elucidation of complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment is probably the most useful 2D NMR method. The ...
-
(1993)When the rat kidney is subjected to ischemia and reperfusion, changes in glutathione content and in lipid peroxidation are produced in the cortex and in the medulla. The cortex shows a decrease in the glutathione content ...
-
(1993)1. 1. In the present study, adenosine modulation on the antinociceptive action of benzodiazepines (BZD) using the writhing test in mice was evaluated. 2. 2. The i.c.v. BZDs tested (diazepam, midazolam and lorazepam) induced ...
-
(1992)1. 1. The sperm nuclei of the marine bivalve mollusc Mesodesma donacium contain four somatic-type histones (H2A, H2B, H3 and H4), one sperm histone H1-like and a sperm-specific protein, named by us M1. 2. 2. The histone ...

(1991)Immunoaffinity chromatography involves binding of an antigen or antibody to a solid matrix, usually agarose, frequently using the cyanogen bromide method. These methods are laborious, rather expensive, and their use has ...
-
(1990)1. The findings, derived from different experimental models, examined in this review, provide evidence that the calcium channel blockers and related drugs possess analgesic effects. 2. The antinociceptive action that some ...
-
(1990)Short or long term diabetes in female rats produced remarkable activation of aminopyrine N-demethylation, inhibition of oestrone and p-nitrophenol glucuronidation and no changes in morphine UDP-glucuronyltransferase activity ...
-
(Informa Healthcare, 1990)Reperfusion of rat kidney submitted to temporal ischaemia induces a decrease in glutathione content. Lipid peroxidation is not detected in kidney homogenates but microsomes obtained after periods of reperfusion longer than ...
-
(1972)Potassic Chilean nitrate, a cheap natural product of northern Chile, was found to support the growth of the unicellular green alga Chlorella pyrenoidosa, a possible sheep fodder supplement in this region. Comparisons with ...
