At low concentrations, 3H-naloxone apparently bound to two sites, of high (KD 0.50 nM) and low (KD 2.0 nM) affinity. Binding to the high affinity site was preferentially blocked by naloxonazine. This is consistent with the high and low affinity sites representing the mu 1 and mu 2 sites respectively. Binding of 3H-naloxone to the mu 1 and mu 2 sites was… (More)
To determine the site of action of imipramine, the subcellular distribution of [3H]imipramine in rodents was followed after both in vivo administration and in vitro incubation with tissue slices under "physiological" conditions. Total [3H]imipramine (10-1,000 nM) binding was associated with all primary fractions, but in particular with the nuclear (P1) and… (More)
Pathways of testosterone metabolism in tissue slices and cell suspensions of human benign hyperplastic prostate (BPH) tissue and human prostate cancer cell lines (DU145, HPC-36M, PC-3/MA2 and LNCaP) were investigated. Thin layer chromatography analysis was used to identify the following tritiated metabolites: testosterone, 5 alpha-dihydrostestosterone… (More)
1. delta9-Tetrahydrocannabinol and cannabidiol both exhibited a concentration-related inhibition of Mg2+-ATPase of vesicles prepared from synaptosomes isolated from rat cerebral cortex. Cannabidiol was about 3 times more potent than tetrahydrocannabinol. 2. These results were similar to those obtained previously using drugs with well established… (More)
Background: A decrease in incidence and major complication rate of ST elevation myocardial infarction (STEMI) has been observed across several population groups.
Study Type – Therapy (RCT) Level of Evidence 1b OBJECTIVE To investigate the relationship between adult male circumcision and sexual satisfaction and function in men, as observational studies on the effect of adult male circumcision on sexual satisfaction show conflicting results. We investigated self-reported sexual satisfaction and function among men… (More)
The relationship between the binding site for imipramine and the uptake system for 5-hydroxytryptamine was examined. This was determined from the interaction between various drugs (including tricyclic antidepressants) and the high affinity accumulation of [3H]5-hydroxytryptamine in cortical synaptosomes from the rat, and with the high affinity binding of… (More)
