Leptin causes nitric-oxide independent coronary artery vasodilation in humans.
Recent studies have shown that leptin causes vasodilation. However, it is unclear whether leptin causes coronary vasodilation in humans. To determine how leptin affects human coronary arteries and whether endothelium-derived nitric oxide (EDNO) is involved in the coronary arterial response to leptin, we infused leptin (0.3, 3 and 30 ng/kg/min) for 2 min into the left coronary ostium before and ...
متن کاملSystemic hypoxia causes cutaneous vasodilation in healthy humans.
Hypoxia and hypercapnia represent special challenges to homeostasis because of their effects on sympathetic outflow and vascular smooth muscle. In the cutaneous vasculature, even small changes in perfusion can shift considerable blood volume to the periphery and thereby impact both blood pressure regulation and thermoregulation. However, little is known about the influence of hypoxia and hyperc...
متن کاملMagnesium causes nitric oxide independent coronary artery vasodilation in humans.
OBJECTIVE To determine how magnesium affects human coronary arteries and whether endothelium derived nitric oxide (EDNO) is involved in the coronary arterial response to magnesium. DESIGN Quantitative coronary angiography and Doppler flow velocity measurements were used to determine the effects of the nitric oxide synthase inhibitor N(G)-monomethyl-L-arginine (L-NMMA) on magnesium induced dil...
متن کاملNoninvasive low-frequency ultrasound energy causes vasodilation in humans.
OBJECTIVES We evaluated the potential vasodilator effects of transcutaneous low-frequency ultrasound (US) in human brachial arteries. BACKGROUND Recent data show that transthoracic low-frequency US energy results in canine coronary artery vasodilation. METHODS Brachial artery diameters were measured before and after low-frequency US (29 kHz, 1.4 W/cm2) exposure using US imaging with a linea...
متن کاملAdipose tissue leptin production and plasma leptin kinetics in humans.
Abdominal adipose tissue leptin production was determined in vivo by arteriovenous balance in 14 lean and obese men (mean BMI 27.0 +/- 1.9, range 21.4-45.2). Blood samples were taken simultaneously from an abdominal vein that drains subcutaneous adipose tissue and from a radial artery. Adipose tissue blood flow was measured by xenon washout. Abdominal vein leptin concentrations (mean 8.9 +/- 2....
