Assessment of microvascular endothelial function in human skin.
Endothelial dysfunction is an important factor in many cardiovascular diseases, and is commonly associated with impaired endothelium-mediated vasodilatation. Information about the mechanisms behind this dysfunction has come largely from animal studies or, in humans, through invasive techniques that are not specific to one vascular bed. We have developed protocols to assess endothelial function ...
متن کاملSelective loss of microvascular endothelial function in human hypercholesterolemia.
BACKGROUND Endothelial dysfunction is increasingly recognized as an early and important feature of vascular disease. Endothelium-dependent vasodilation is impaired in humans with hypercholesterolemia, although it is unknown whether this defect is selective for some pathways of nitric oxide production or indicates a more generalized abnormality of endothelial function. The aim of this study was ...
متن کاملMicrovascular endothelial function in Japanese early adolescents
Endothelial dysfunction is the early predictive factor for the development of atherosclerosis and future cardiovascular diseases in adulthood. The prevalence of endothelial dysfunction in children and early adolescents is increasing worldwide. Peripheral arterial tonometry is a noninvasive technique for assessing peripheral microvascular function and is used as a validated marker of endothelial...
متن کاملEndothelial Vasodilator Angiotensin Receptors are Changing in Mice with Ageing
Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice. Materials and Methods: Male C57Bl mice (aged 4 and 14 months) were killed by CO2. The descending thoracic aorta was cleaned and dissected into rings. Aortic rings were mounted in Krebs’ solution at 37 °C an...
متن کاملAprotinin impairs coronary endothelial function and down-regulates endothelial NOS in rat coronary microvascular endothelial cells.
OBJECTIVE The non-specific serine protease inhibitor aprotinin is currently used to reduce blood loss and the need for blood transfusion after cardiopulmonary bypass. We have recently reported that aprotinin impairs endothelium-dependent but not endothelium-independent relaxations in rat thoracic aortic rings due to its inhibitory effect on endothelial nitric oxide (NO) production. In light of ...
