Comparison of "selective" opiate receptor antagonists on the isolated mouse vas deferens
(Elsevier, 1984-12)
The selectivity and relative potencics of opiate receptor antagonists were compared on the mouse vas deferens preparation. ICI-174864 was found to be a highly selective antagonist at delta opiate receptors equal in potency ...
Solid phase enzyme-linked competitive binding assay for riboflavin
(Elsevier, 1988-01)
A new solid-phase enzyme-linked assay for riboflavin (vitamin B2) is described. The assay is based on the competition between analyte vitamin molecules and a glucose-6-phosphate dehydrogenase-3-carboxymethylriboflavin ...
Evidence that isoniazid and ethanol induce the same microsomal cytochrome P-450 in rat liver, an isozyme homologous to rabbit liver cytochrome P-450 isozyme 3a
(Elsevier, 1986-05-01)
Cytochrome P-450j has been purified to electrophoretic homogeneity from hepatic microsomes of adult male rats administered ethanol and compared to the corresponding enzyme from isoniazid-treated rats. The enzymes isolated ...
Chromogranin from normal human adrenal glands: purification by monoclonal antibody affinity chromatography and partial N-terminal amino acid sequence
(Elsevier, 1986-02)
A method is presented for the purification of human chromogranin from adrenal glands obtained at autopsy. The procedure involved homogenization of whole glands in aqueous buffer, salt precipitation, affinity chromatography ...
Involvement of 1,25-dihydroxyvitamin D3 in regulating myocardial calcium metabolism: Physiological and pathological actions
(Elsevier, 1988)
The role of the prohormone vitamin D3 in regulating calcium and phosphate metabolism in the intestine, kidney, and bone has been known for several decades [1]. Recent studies have provided evidence that vitamin D3, may ...
Protein microinjection by protease permeabilization of fibroblasts
(Elsevier, 1988-07)
Exposure of cultured diploid fibroblasts to protease solutions induces a hyperpermeable state which permits entry of exogenous macromolecules directly into the cytosol. We have exploited this finding to devise a microinjection ...
Separation of hemoglobin types by cation-exchange high-performance liquid chromatography,
(Elsevier, 1983-10-01)
The use of a recently developed cation-exchange HPLC packing material for the separation of hemoglobin types in human blood has been investigated. Adult and newborn hemolysates from normal individuals and from subjects ...
Lectin binding studies on murine peritoneal cells: Physicochemical characterization of the binding of lectins from Datura stramonium, Evonymus europaea, and Griffonia simplicifolia to murine peritoneal cells
(Elsevier, 1986-01)
Purified 125I-labeled lectins from Datura stramonium, Evonymus europaea, and Griffonia simplicifolia (I-B4 isolectin) were used to analyze changes in the expression of carbohydrates on the surface of resident (PC) and ...
Free radicals in ischemic myocardial injury
(Elsevier, 1985)
Myrocardial ischemia causes release of chemotactic factors, migration of neutrophils, peroxidation of lipids, and depletion of free radical scavengers. The invading neutrophils may injure the myrocardial vasculature and ...
The distribution of cholecystokinin and vasoactive intestinal peptide in rhesus monkey brain as determined by radioimmunoassay
(Elsevier, 1983-07)
The concentration of cholecystokinin (CCK) and vasoactive intestinal peptide (VIP) in dissected cortical and subcortical areas of four rhesus monkeys' brains was determined by radioimmunoassay (RIA). Cerebral cortical ...
