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 ...
A convenient masking group for aryl iodides
(Elsevier, 1991-11-27)
1-Aryl-3,3-dialkyltriazenes give excellent yields of easily isolated aryl iodides upon treatment with methyl iodide.
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 ...
Modeling of immunosensors under nonequilibrium conditions : II. Experimental determination of performance characteristics
(Elsevier, 1991-08-01)
In an attempt to optimize immunosensors operating with an immobilized antibody as binding protein and an analyte-enzyme conjugate as signal generator that is significantly larger in molecular size than the analyte, in a ...
Synthesis of 4-Amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine; an entry into a novel series of adenosine analogs
(Elsevier, 1991)
The synthesis of a novel adenosine analog, 4-amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine, has been accomplished using pyrrole nucleoside precursors.
Pathway of formation and catalase activity in a dioxo bridged Mn(IV) dimer.
(Elsevier, 1991-08)
Neopentane reactions over bimetallic Pt---Sn/AI2O3 and Pt---Au/SiO2 catalysts
(Elsevier, 1991-12)
The reaction of 2,2-dimethylpropane (neopentane) with hydrogen was studied over two series of supported bimetallic catalysts containing platinum as the primary group VIII metal and either gold or tin as the second metallic ...
A chemisorption and XPS study of bimetallic Pt-Sn/Al2O3 catalysts
(Elsevier, 1991-01)
Bimetallic Pt-Sn/Al2O3 catalysts with nominally 1 wt% Pt and varying tin contents (0-3.25 wt%) prepared by coimpregnation of nonporous Degussa alumina were characterized by chemisorption of H2, O2, and CO at room temperature. ...
Purification and characterization of cytochrome P450 2E2 from hepatic microsomes of neonatal rabbits
(Elsevier, 1991-12)
The alcohol-inducible P450 2E subfamily in the rabbit has two known members that differ in only 16 amino acid residues scattered throughout the polypeptide chain. P450 2E1 has been thoroughly characterized, and is known ...
