Lectin-based homogeneous enzyme-linked binding assay for estimating the type and relative amount of carbohydrate within intact glycoproteins
(Elsevier, 1992-04)
The feasibility of using a new lectin-based homogeneous enzyme-linked binding assay for estimating the type and relative amount of specific carbohydrate structures within intact glycoproteins is examined. Malate ...
In Vitro release of hypothalamic [beta]-endorphin [beta]E by arginine vasopressin, corticotropin-releasing hormone and 5-hydroxytryptamine: Evidence for release of opioid active and inactive [beta]E forms
(Elsevier, 1990-05)
The aims of the present experiments were: 1) to test whether substances which modulate beta-endorphin-immunoreactive [beta]E-ir release from the pituitary gland might act similarly in hypothalamic tissue; and 2) to further ...
Photoperiodic effects on hypothalamic [beta]-endorphin and POMC mRNA
(Elsevier, 1994-11-10)
Lung injury and complement activation: Role of neutrophils and xanthine oxidase
(Elsevier, 1991)
Evidence is presented that oxygen products generated from xanthine oxidase (XO) may also be involved in the pathogenesis of neutrophil-mediate lung injury following intravascular activation of complement with cobra venom ...
Glucosylceramide synthase of mouse kidney: Further characterization with an improved assay method
(Elsevier, 1990-12)
The synthesis of glucosylceramide from ceramide and UDP-[3H]glucose by mouse kidney homogenates is very sensitive to the concentration of tissue. This was shown to be due to the presence of a UDP-glc pyrophosphatase, which ...
Design, synthesis and activity against human cytomegalovirus of non-phosphorylatable analogs of toyocamycin, sangivamycin and thiosangivamycin
(Elsevier, 1992-12)
A number of 7-alkyl 4-aminopyrrolo[2,3-pyrimidine derivatives related to toyocamycin, sangivamycin and thiosangivamycin have been prepared and tested for their activity against human cytomegalovirus (HCMV). Only the thioamide ...
Determination of plasma propofol levels using gas chromatography--mass spectrometry with selected-ion monitoring
(Elsevier, 1993-10-29)
Propofol (2,6-diisopropylphenol, I.C.I. 35 868) is a rapid-acting, intravenous anesthetic agent recently introduced for the induction and maintenance of general anesthesia. This paper describes a gas chromatographic--mass ...
Baculovirus-Mediated Expression of Rat Liver CTP:Phosphocholine Cytidylyltransferase
(Elsevier, 1993-02)
We describe herein the expression and purification of milligram quantities of rat liver CTP:phosphocholine cytidylyltransferase in recombinant baculovirus-infected insect cells. The enzyme was purified by incorporating ...
Lipoxygenase-generated icosanoids inhibit glucose-induced insulin release from rat islets
(Elsevier, 1990-05)
Lipoxygenase-pathway metabolites of arachidonic acid are produced in pancreatic islets. They are are implicated in insulin release, since nonselective inhibitors of lipoxygenases inhibit glucose-induced insulin release. ...
Ferrous iron release from transferrin by human neutrophil-derived superoxide anion: Effect of pH and iron saturation
(Elsevier, 1991-01)
The ability of superoxide anion (O2-) from stimulated human neutrophils (PMNs) to release ferrous iron (Fe2+) from transferrin was assessed. At pH 7.4, unstimulated PMNs released minimal amounts of O2- and failed to ...
