Glutamate uptake system in the presynaptic vesicle: Glutamic acid analogs as inhibitors and alternate substrates
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-01)
A variety of naturally occurring amino acids, their isomers, and synthetic analogs were tested for their ability to inhibit uptake of [ 3 H]glutamate into presynaptic vesicles from bovine cerebral cortex. Strongest inhibition ...
Tyrosine hydroxylase mRNA-containing neurons in the medial amygdaloid nucleus and the reticular nucleus of the thalamus in the Syrian hamster
(Elsevier, 1993-11)
To confirm previous immunocytochemical findings in colchicine-treated Syrian hamsters, in situ hybridization was used to investigate the distribution of TH mRNA-containing cells in the medial amygdaloid nucleus (Me) and ...
Simultaneous enzymatic/electrochemical determination of glucose and L -glutamine in hybridoma media by flow-injection analysis.
(Wiley Subscription Services, Inc., A Wiley Company, 1993-04-25)
A split-stream flow-injection analysis system is described for simultaneous determination of glucose and L -glutamine in serum-free hybridoma bioprocesses media. Amperometric measurement of glucose is based on anodic ...
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 ...
Metabolic diversity of aromatic hydrocarbon-degrading bacteria from a petroleum-contaminated aquifer
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-12)
We characterized bacteria from contaminated aquifers for their ability to utilize aromatic hydrocarbons under hypoxic (oxygen-limiting) conditions (initial dissolved oxygen concentration about 2 mg/l) with nitrate as an ...
Chemical sequencing of disulfide-crosslinked oligodeoxyribonucleotides
(Elsevier, 1993-10)
Oligodeoxyribonucleotides containing a novel disulfide crosslink are shown to be amenable to chemical sequencing using standard sequencing reagents following reduction of the disulfide with DTT and selective alkylation of ...
Structural Heterogeneity of Caucasian N-Acetyltransferase at the NAT1 Gene Locus
(Elsevier, 1993-02-15)
The human N-acetylation polymorphism is a genetic trait phenotypically reflected by differences in N-acetyltransferase (NAT) activity with therapeutic agents (rapid and slow acetylation), but a genetic invariability in ...
