-
(1996)Body Fe homeostasis is maintained through the regulation of Fe absorption by the intestinal epithelia. Working under the hypothesis that the intracellular concentration of Fe is instrumental in the control of its transepithelial ...
-
(1995)A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
-
(1992)The major heat shock proteins from Thiobacillus ferrooxidans were identified as DnaK and GroEL equivalents by Western blotting and analysis of the N-terminal amino acid sequence of spots isolated from dried 2-D polyacrylamide ...
-
(1995)The reptilian brain is characterized by a structure that bulges into the lateral ventricle, cabled dorsal ventricular ridge (DVR). The DVR was originally considered to be a part of the basal ganglia, although more recent ...
-
(1995)Plant defense against pathogens involves mechanisms that include the expression of several genes, which could be located in any of the three compartments that contain genomes in plant cells: nuclei, mitochondria and ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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)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 ...
-
(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 ...
