The aim of the current study is to demonstrate normal and malignant prostatic epithelial cells (PrECs) as targets for receptor-mediated estrogenic and antiestrogenic action. Using an improved protocol, we have successfully isolated and maintained highly enriched populations of normal PrECs from ultrasound-guided peripheral zone biopsies, individually(More)
Recent studies have demonstrated a hypoalgesia in hypertensive subjects. This study reports and evaluates factors responsible for the expression of the hypoalgesic behavior demonstrated by genetically hypertensive rats of the Okamoto-Aoki strain (SHR) as compared to normotensive age-matched Wistar-Kyoto rats (WKY). Analgesiometric assays were conducted by(More)
A new dopamine analog, 6,7-dihydroxy-2-dimethylaminotetralin (TL-99), was compared to apomorphine in three tests of dopaminergic function in the central nervous system. The tests, performed on rats, included production of changes in locomotor activity (involving both presynaptic and postsynaptic receptors), inhibition of dopa accumulation (quantifying(More)
d-Amphetamine was found to induce a pecking response in pigeons. The pecking response induced by d-amphetamine was antagonized by chlorpromazine, haloperidol or bulbocapnine indicating that this pecking response was caused by dopaminergic receptor stimulation. Pretreatment of pigeons with alpha-methyltyrosine (alpha-MT) reduced d-amphetamine-induced(More)
CD134 (OX40) is a member of the TNF receptor family that is expressed on activated T lymphocytes. T cells from mice that lack expression of CD134 made strong responses to a range of challenges, but they showed impaired proliferation in response to direct stimulation through the TCR with monoclonal anti-CD3epsilon Ab. CD134-deficient mice controlled(More)
The studies show that unilateral microinjection of nitroglycerin (NTG) into nucleus tractus solitarii (NTS) produce dose-dependent decreases in mean arterial pressure (MAP) and heart rate, but injection of sodium nitroprusside (SNP) into the area induced slight effects. Hypotensive responses to NTG injected into the NTS showed that the compound was 20 times(More)

Nitroglycerin produced concentration-dependent increases in spontaneous rate and enhancements of positive chronotropic and inotropic responses to transmural stimulation of isolated right guinea-pig atria. The effects of nitroglycerin were significantly potentiated by desmethylimipramine, which is an inhibitor of norepinephrine uptake, and were significantly(More)
