Excitatory amino acid (EAA) analogues activate receptors that are coupled to the increased hydrolysis of phosphoinositides (PIs). In these studies, hippocampal slices were prepared from neonatal rats (6-11 days old) to characterize the effects of EAA analogues on these receptors. The concentrations of ibotenate and(More)
The excitatory amino acid analogues L-glutamate (L-Glu), L-aspartate (L-Asp), D-Asp, and trans-(+-)-1-amino-1,3-cyclopentanedicarboxylate (trans-ACPD) stimulate the hydrolysis of phosphoinositides (PI). In the present studies, the effects of noncompetitive and competitive inhibitors on PI hydrolysis stimulated by excitatory amino acid analogues were(More)
The conformationally constrained cyclobutane analogues of quisqualic acid (Z)- and (E)-1-amino-3-[2'-(3',5'-dioxo-1',2', 4'-oxadiazolidinyl)]cyclobutane-1-carboxylic acid, compounds 2 and 3, respectively, were synthesized. Both 2 and 3 stimulated phosphoinositide (PI) hydrolysis in the hippocampus with EC50 values of 18 +/- 6 and 53 +/- 19 microM,(More)
PURPOSE We conducted a Phase II trial of bryostatin-1, an inhibitor of protein kinase C, in advanced renal cell carcinoma to measure toxicity, response rate, time to progression, and induction of cytokines. EXPERIMENTAL DESIGN A total of 32 patients (26 male and 6 female) received bryostatin-1 at 35-40 microg/m(2) i.v. over 1 h on days 1, 8, and 15 of(More)
L-Glutamic acid (L-Glu) and L-aspartic acid (L-Asp) activate several receptor subtypes, including metabotropic Glu receptors coupled to phosphoinositide (PI) hydrolysis. Quisqualic acid (Quis) is the most potent agonist of these receptors. There is evidence that activation of these receptors may cause a long lasting sensitization of neurons to(More)
We discuss our study on the effects of discontinuation of the usage of bone wax as a hemostatic agent in sternotomy incisions. In 1976, we abandoned use of bone wax because it was suspected of causing several cases of Mycobacterium fortuitum sternal osteomyelitis. In a retrospective study involving 400 patients, we found that this step did not increase(More)
