Comparison of SnBr 4 and di-n-butyl tin diacetate as laser-assisted chemical vapor deposition precursors for SnO 2 -based gas sensors
(John Wiley & Sons, Ltd., 1998-03)
Laser-assisted chemical vapor deposition (LCVD) was utilized to produce SnO 2 films from SnBr 4 plus air, O 2 or N 2 O. SnO 2 films were successfully generated using either 222 or 308 14nm laser pulses but there was ...
Initiation of poly-N-acetyllactosamine chain biosynthesis occurs preferentially on complex multiantennary asparagine-linked oligosaccharides
(Elsevier, 1990-08-01)
An N-acetyl-[beta]--glucosaminyltransferase activity involved in the initiation of poly-N-acetyllactosamine chain biosynthesis can be solubilized from Ehrlich ascites tumor cell microsomal membranes. The ability of this ...
Ethanol effects on self-administration of alfentanil, cocaine, and nomifensine in rhesus monkeys
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-04)
A common form of polydrug use is that of cocaine and ethanol. The identification of an ethanol-cocaine combination product, cocaethylene, with properties in common with cocaine, has led to speculation that this metabolite ...
The selectivity of hydrazine oxidation on a polycrystalline rhodium surface
(Elsevier, 1991-11-02)
The surface reactions of coadsorbed hydrazine and atomic oxygen have been examined by means of temperature-programmed reaction spectroscopy (TPRS) on a clean polycrystalline rhodium surface over the 90 to 1450 K temperature ...
Abnormalities of autonomic nervous control in human hypertension
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-03)
The pathophysiology of various stages of hypertension is different. In early hyperkinetic borderline hypertension, the sympathetic drive to the heart and blood vessels is increased while the parasympathetic cardiac inhibition ...
Certain 8-amino-9-(benzyl)guanines as potential purine nucleoside phosphorylase inhibitors
(Elsevier, 1994)
Several 8-amino-9-(benzyl)guanines were selected for synthesis as potential purine nucleoside phosphorylase (PNP) inhibitors on the basis of the Topliss decision tree. These compounds were prepared by the treatment of ...
Molybdenum/cobalt/sulfur clusters: Models and precursors for hydrodesulfurization (HDS) catalysts
(John Wiley & Sons Ltd., 1992-09)
Sulfido clusters which incorporate molybdenum and a late transition metal, e.g. iron, cobalt or nickel, are readily prepared by the reactions of Cp 2 Mo 2 S 4 , Cp 2 Mo 2 S 2 (SR) 2 or Cp 2 Mo 2 (CO) 2 (SR) 2 with Fe 2 ...
Steroid Metabolism by Rabbit Olfactory-Specific P450 2G1
(Elsevier, 1994-12)
Cytochrome P450 2G1 (2G1), which is uniquely expressed in the olfactory mucosa in mammals, may have important physiological functions. In the present study, we have examined the catalytic activity of rabbit 2G1 toward a ...
DNA-binding and non-DNA-binding forms of the transformed glucocorticoid receptor
(Elsevier, 1992-03)
In this work we have probed the mechanism responsible for two non-DNA-binding states of the mouse glucocorticoid receptor. In the first case, transformed receptors were treated with hydrogen peroxide. It is known that ...
