Sympathetic neural activation in visceral obesity.
BACKGROUND Muscle sympathetic nerve activity (MSNA) is elevated in obese humans. However, the potential role of abdominal visceral fat as an important adipose tissue depot linking obesity to elevated MSNA has not been explored. Accordingly, we tested the hypothesis that MSNA would be increased in men (age=18 to 40 years, body mass index < or =35 kg/m2) with higher abdominal visceral fat (HAVF; ...
متن کاملSubcutaneous obesity is not associated with sympathetic neural activation.
We tested the hypothesis that muscle sympathetic nerve activity (MSNA) would not differ in subcutaneously obese (SUBOB) and nonobese (NO) men with similar levels of abdominal visceral fat despite higher plasma leptin concentrations in the former. We further hypothesized that abdominal visceral fat would be the strongest body composition- or regional fat distribution-related correlate of MSNA am...
متن کاملAn affair of the heart.
In 1950, patients with Hodgkin lymphoma had a median survival time of 4 years and a 5-year relative survival rate of 29% (1). Since the introduction of radiation therapy and chemotherapy for Hodgkin lymphoma in the 1960s and 1970s, the 5-year relative survival rate is more than 85% (2), and these patients can now expect a long lymphoma-free life. However, the price for this phenomenal success h...
متن کاملSympathetic activation by sildenafil.
BACKGROUND Sildenafil citrate is an effective and widely prescribed therapy for erectile dysfunction. Little is known about the effects of sildenafil on neural control of the circulation or about the effects of sildenafil on neurocirculatory stress responses. METHODS AND RESULTS We studied 14 normal volunteers (age 32+/-7 years) who were randomized in a double-blind crossover fashion to recei...
متن کاملSympathetic Nervous Activation and Failure
Background Although heart rate variability (HRV) at 0.1 Hz has been proposed as a noninvasive clinical measure of cardiac sympathetic nerve firing, this premise has not been sufficiently validated by comparison with techniques such as microneurography and the measurement of norepinephrine spillover from the heart that more directly reflect presynaptic sympathetic activity. Methods and Results W...
