Purification of Dihydroxyacetone Phosphate Acyltransferase from Guinea Pig Liver Peroxisomes
(Elsevier, 1993-01)
Dihydroxyacetone phosphate acyltransferase (EC 2.3.1.42), a peroxisomal enzyme which initiates the biosynthesis of glycerolipids (especially the ether-linked glycerolipids) in higher eukaryotes, has been purified by over ...
Kinetics of aerobic biodegradation of benzene and toluene in sandy aquifer material
(Kluwer Academic Publishers; Springer Science+Business Media, 1991-03)
Monod's equation adequately described aerobic biodegradation rates of benzene and toluene by the microbial population of a sandy aquifer when these compounds were initially present at concentrations lower than 100 mg/l ...
Effects of tobacco smoking on the topographic EEG I
(Elsevier, 1994-09)
1. 1. The EEG and cardiovascular effects of smoking tobacco cigarettes of varying nicotine content were studied in Japanese chronic tobacco smokers.2. 2. Thirteen female and fifteen male adult normal volunteers were recruited ...
Dexamethasone attenuation of the cortisol response to nicotine in smokers
(Springer-Verlag, 1990-06)
The effect of corticosteroids upon the cortisol response to nicotine from smoking was investigated in five heavy smokers. Corticosteroid activity was manipulated by administering dexamethasone, a synthetic glucocortoicoid ...
NF1-related locus on chromosome 15
(Elsevier, 1992-08)
A neurofibromatosis type I (NF1)-related locus has been identified on chromosome 15. It contains a partial copy of the NF1 GAP-related domain, which is known to interact with the ras protooncogenes. However, the chromosome ...
Heating characteristics and atomic emission waveforms for glow discharge ion bombardment furnaces
(Elsevier, 1991)
Ion bombardment of a graphite cathode in a glow discharge plasma is used to heat the cathode to temperatures suitable for the vaporization of solution residues from the cathode surface. Two low-mass cathode configurations ...
Extraction of aminoglycoside antibiotics with reverse micelles
(John Wiley & Sons, Ltd., 1996-01)
The reverse micelle system of sodium di-2-ethylhexyl phosphate was used to extract aminoglycoside antibiotics, neomycin and gentamicin. The aminoglycosides can be efficiently extracted into a reverse micelle solution, and ...
Isolation and sequence analysis of CDC43, a gene involved in the controol of cell polarity in Saccharomyces cerevisiae
(Elsevier, 1990-05-31)
The Saccharomyces cerevisiae CDC43 gene product is involved in establishing cell polarity during the cell-division cycle. When grown at restrictive temperatures, temperature-sensitive cdc43 mutants are unable to form buds ...
The NMDA receptor antagonist MK-801 increases morphine catalepsy and lethality
(Elsevier, 1991-03)
Interactions between excitatory amino acids and opioids were examined by studying the ability of the noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist MK-801 to affect morphine catalepsy and lethality. MK-801 ...
A comparison of proteins and peptides as substrates for microsomal and solubilized oligosaccharyltransferase
(Elsevier, 1994-11)
A chemoenzymatic synthesis of homogeneous neoglycoproteins and glycopeptides was explored using oligosaccharyltransferase isolated from yeast. Neither the microsomal form nor the solubilized form of the enzyme catalyzed ...
