(Elsevier Ltd, 1996)A process of recovery of copper from acid leach residual solution with 5-dodecylsalicylaldoxime dissolved in n-hexane was carried out at 30°C in a countercurrent tubular membrane extractor using a hollow fiber as solid ...
-
(1995)The metabolites that mediate coronary reactive hyperemia have not been definitely identified. Although adenosine and endothelium derived substances seem to be involved, their relative contributions have not been defined ...
-
(1995)In this study, we tested the adhesion-promoting role of major intrinsic protein from both normal human (cadaver) and senile cataractous lenses. Junctional membrane solubilized proteins and pure major intrinsic protein ...
-
(1994)This paper illustrates, with a specifie example, the methodology presented in a previous paper for the exergoeconomic optimization of complex, multicomponent-multiproduct systems. The application selected is a cogeneration ...
-
(1995)Phosphoenolpyruvate carboxykinase (PEPCK) from the adductor muscle of Perumytilus purpuratus was purified to homogeneity, as determined by SDS-polyacrylamide gel electrophoresis (PAGE). The purification consisted of a ...
-
(Academic Press Inc., 1995)Eggs of the leech Theromyzon rude were studied under dissecting, fluorescence, light, and electron microscopes. The sperm-derived centrosome divides and separates at early first interphase. The female pronucleus forms ...
-
(1995)1. 1. Streptozotocin-induced diabetes produced significant changes on the drug metabolizing enzyme machinery of rat kidney microsomes. 2. 2. It reduced the cytochrome P-450 content by 30%, this effect being reversed by ...
-
(1995)Bromination of 2,4,6-tri-O-benzoyl-3-deoxy-d-erytro-hex-2-enono-1,5-lactone (1) took place diastereoselectively to afford a single product: 2,4,6-tri-O-benzoyl-2,3-dibromo-3-deoxy-d-altrono-1,5-lactone (2). The configuration ...
-
(1994)Boldo (Peumus boldus Mol.), a Chilean tree traditionally employed in folk medicine and recognized as a herbal remedy in a number of pharmacopoeias, mainly for the treatment of liver ailments, has recently been the subject ...
-
(1991)Boldine shows a concentration-dependent relaxation effect on the rat ileum preparation with a pD2 of 3.77 ± 0.12. The alkaloid also produces a concentration-dependent parallel shift of the curve-response to acetylcholine, ...
-
(1994)1. The effects of an infusion of cytidine-5′-diphosphocholine (CDP-choline) on the relaxation induced by exogenous acetylcholine (ACh) was studied in the isolated and perfuded external (ECB) and internal (ICB) carotid ...
-
(1994)A cDNA clone coding for human protein kinase CK1 (casein kinase 1) has been isolated and sequenced demonstrating that it corresponds to a homolog of the CK1α form found in bovine brain. The derived amino acid sequence of ...
-
(1994)A polarographic method for the determination of ranitidine is described, based on the reduction of the nitro group at a dropping-mercury electrode. The proposed method permits the drug to be determined, without any prior ...
-
(1994)The cyclic voltammetric behavior of nicardipine was studied. Particular attention was directed to the one-electron ArNO2/ArNO2•- couple as measured by the cyclic voltammetric mode in aqueous DMF mixed media. Analysis of ...
-
Subcellular remodeling of the T-tubule membrane system: The limits of myocardial recovery revealed? (Lippincott Williams and Wilkins, 2017)
-
(1993)Objective: The aim was to clarify the role of cyclic AMP dependent protein kinase (PKA) and changes in mechanical heart function during development of cardiac hypertrophy induced by volume overload. Methods: Protein and ...
-
(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 ...
-
(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 ...
