Leptin and nitric oxide in blood pressure regulation in humans.
To the Editor: We read with great interest the article “Leptin in Association With Common Variants of MC3R Mediates Hypertension” by Alsmadi and colleagues1 dealing with the relationship between polymorphisms of leptin gene and blood pressure levels in humans. The results of their study demonstrated that the MC3R missense variant (rs3827103) might be associated with systolic blood pressure in K...
متن کاملCerebral blood velocity regulation during progressive blood loss compared with lower body negative pressure in humans.
Lower body negative pressure (LBNP) is often used to simulate blood loss in humans. It is unknown if cerebral blood flow responses to actual blood loss are analogous to simulated blood loss during LBNP. Nine healthy men were studied at baseline, during three levels of LBNP (5 min at -15, -30, and -45 mmHg), and during three levels of blood loss (333, 667, and 1,000 ml). LBNP and blood loss cond...
متن کاملBlood pressure regulation in pheochromocytoma.
Two sets of studies were performed in 13 patients with proved adrenal pheochromocytoma to test the hypothesis that the sympathetic nervous system (SNS) is active and might contribute to the hypertensive state. Similar studies were performed in 15 additional patients considered to have essential hypertension. In the first set, 13 patients with pheochromocytoma were subjected to head-up tilt to a...
متن کاملeonatal Blood Pressure Regulation
ypertension is often viewed solely as a disease of the adult. However, early indicators of hypertenion are frequently observed in young children and neonates. Having an adequate appreciation of the ormal range of infant blood pressure is critical for the appropriate management of the conditions ssociated with elevated or abnormally low blood pressure. In healthy neonates, systolic blood ressure...
متن کاملBlood pressure regulation in humans: calculation of an "error signal" in control of sympathetic nerve activity.
Within an individual, diastolic blood pressure (DBP) is negatively related to sympathetic burst incidence, such that lower pressure is associated with high burst incidence. Our goal was to explore the use of a calculation of a DBP "error signal" in the control of muscle sympathetic nerve activity in men and women. Baseline muscle sympathetic nerve activity was measured in healthy young men (n=2...
