This paper describes a method for imaging the endogenous release of glutamate from cerebral neurons. This method is based on the reactions of glutamate oxidase and peroxidase, and on the detection of hydrogen peroxide by a fluorescent substrate of peroxidase. Glutamate has been sensitively measured in vitro in the range of 20 nM to 1 microM. We used two(More)
BACKGROUND We have previously reported that 10 patients who developed glomerulonephritis (GN) in association with methicillin-resistant Staphylococcus aureus (MRSA) infection showed a marked increase in DR+CD4+ and DR+CD8+ subsets of T cells and in T cells expressing several T-cell receptor (TCR) V beta+cells, perhaps representing V beta-specific T-cell(More)
OBJECT Tyrosine kinases play an important role in the regulation of systemic vascular smooth-muscle tone. The authors studied the involvement of protein tyrosine kinase activity in erythrocyte lysate-mediated signal transduction in cerebral smooth-muscle cells. METHODS Tyrosine kinase phosphorylation and intracellular free Ca++ ([Ca++]i) were measured in(More)
Syntheses of 15 alpha- and 15 beta-carboxymethyltestosterone (15 alpha- and 15 beta-CMT) were investigated in order to prepare testosterone-bovine serum albumin conjugates for radioimmunoassays of testosterone. A mixture of 15 alpha- and 15 beta-bis(ethoxycarbonyl)methyl-3 beta-hydroxy-5-androsten-17-one (IIa and IIb) obtained by a reaction of 3(More)
