Melatonin has previously been reported to influence cell differentiation and growth in a number of cell culture systems in vitro. In this paper, we describe the effects of high pharmacological and low physiological concentrations of melatonin on cell growth in rat pheochromocytoma cells (PC12 cells). Melatonin produced a biphasic response with respect to(More)
Resiniferatoxin (RTX) is the most potent among all known endogenous and synthetic agonists for the transient receptor potential vanilloid 1 (TRPV1) receptor, which is a calcium-permeable nonselective cation channel, expressed on the peripheral and central terminals of small-diameter sensory neurons. Prolonged calcium influx induced by RTX causes(More)
This study was performed to determine the effect of shoulder extension and flexion, imaging plane, and intraarticular paramagnetic contrast medium administration on the visibility of soft tissue structures surrounding the canine shoulder joint using magnetic resonance (MR) imaging. Eight dogs without shoulder disease were imaged using a 1.5 T MR scanner. In(More)
