METHODS Projects underway aim to promote the(More)
BACKGROUND Chronic overexpression of an inwardly rectifying potassium channel (hKir2.1) in the paraventricular nucleus of the hypothalamus (PVN) and in the rostral ventrolateral medulla (RVLM) to suppress neuronal excitability, resulted in a long term decrease of blood pressure and sympathetic output in spontaneously hypertensive rats (SHR). OBJECTIVE(More)
Mortality and morbidity by toxic metals is an important issue of occupational health. Lead is an ubiquitous heavy metal in our environment despite having no physiological role in biological systems. Being an homeostatic controller is expected that the autonomic nervous system would show a degree of impairment in lead toxicity. In fact, sympathoexcitation(More)
BACKGROUND It is well established that sympathetic nervous system is responsible for the onset, development and maintenance of neurogenic hypertension. The rostroventrolateral medulla (RVLM) and medullo-cervical pressor area (MCPA) are important central sympathoexcitatory regions whose role on neurogenic hypertension remains unknown.
