PURPOSE To investigate the ability of the nitroxide free radical and superoxide dismutase mimic 4-hydroxy-2,2,6,6-tetramethylpiperidine-n-oxyl (TEMPOL) to protect against x-ray-induced lens DNA damage and cataract formation in the rabbit. METHODS Eleven gray (Gy) x-rays was delivered twice, with a 48-hour interval, to the same eye of 5-week-old rabbits.(More)
PURPOSE In view of the antioxidant role of ascorbic acid and the glutathione redox cycle in the lens, the authors have studied the relationship of the cycle to reduction of the oxidized product of ascorbic acid, dehydroascorbic acid (DHA), in lens epithelium. METHODS Cultured dog lens epithelial cells and intact rabbit lenses were exposed to various(More)
Mutations in p150glued cause hereditary motor neuropathy with vocal cord paralysis (HMN7B) and Perry syndrome (PS). Here we show that both overexpression of p150glued mutants and knockdown of endogenous p150glued induce apoptosis. Overexpression of a p150glued plasmid containing either a HMN7B or PS mutation resulted in cytoplasmic p150glued-positive(More)
Recent studies have demonstrated that magnetic stimulation (MS) can induce cellular responses such as Ca2+ influx into the cultured neurons and glia, leading to increased intracellular phosphorylation. We have demonstrated previously that MS reduces rat neuropathic pain associated with the prevention of neuronal degeneration. Thus, we aimed to elucidate the(More)
Neurotropin (NTP)®, a non-protein extract isolated from the inflamed skin of rabbits inoculated with vaccinia virus, is used clinically for the treatment of neuropathic pain. Moreover, NTP may activate the descending pain inhibitory system. Depression-like behavior is often complicated by chronic pain. However, little is known about NTP-mediated prevention(More)
