Effects of Oxygen on Perioperative Vascular Function: A Randomized Clinical Trial

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Vascular dysfunction contributes to postoperative organ injury. Exposure to high concentrations of oxygen during surgery is common and may impair vascular function.

Different Prostanoids Are Involved in Bradykinin-Induced Endothelium-Dependent and -Independent Vasoconstriction in Rat Mesenteric Resistance Arteries

Journal of Pharmacological Sciences, 2004
Mechanisms underlying bradykinin-induced vasoconstriction were investigated in rat perfused mesenteric vascular beds with active tone. In preparations with intact endothelium, bolus injections of bradykinin (1 to 1,000 pmol) dose-dependently produced ...

Characterization of the Inhibitory Effect of Vascular Endothelium on Agonist-Induced Vasoconstriction in Rat Mesenteric Resistance Arteries

Journal of Pharmacological Sciences, 2008
Vascular endothelium regulates vascular tone by releasing endothelium-derived vasoactive substances. We performed this study to characterize the inhibitory effect of the endothelium on vasoconstrictor stimuli in rat mesenteric vascular beds.

Transforming Endothelium with Platelet‐Rich Plasma in Engineered Microvessels

Advanced Science, 2019
Vascularization remains an obstacle when engineering complex tissues for regeneration and disease modeling. Although progress has been made in recreating 3D vascular structures, challenges exist in generating a mature, functional endothelium.

Hypoxia, vascular smooth muscles and endothelium

Acta Pharmaceutica Sinica B, 2013
Hypoxia, or the lack of oxygen, has multiple impacts on the vascular system. The major molecular sensors for hypoxia at the cellular level are hypoxia inducible factor and heme oxygenase.

Ruthenium Complex Improves the Endothelial Function in Aortic Rings From Hypertensive Rats

Arquivos Brasileiros de Cardiologia
Background: The endothelium is a monolayer of cells that extends on the vascular inner surface, responsible for the modulation of vascular tone. By means of the release of nitric oxide (NO), the endothelium has an important protective function against ...

Vascular endothelium protective property of curcumin

Turkish Journal of Vascular Surgery, 2021
Objectives: In the present study, we aimed to examine the efficacy of curcumin on endothelial vascular protection on human umbilical vein endothelial cells (HUVEC) cells in the in vitro setting and to determine effective doses.

Understanding Vascular Endothelium

L’annuaire du Collège de France, 2014
Understanding Vascular Endothelium : Nature’s Container for Blood The entire cardiovascular system, from the chambers of the heart to the smallest capillaries of peripheral tissues, is lined by a single-cell-thick continuous layer—the vascular endothelium.

Responses to neither exogenous nor endogenous endothelin-1 are altered in patients with hypercholesterolemia

Journal of Lipid Research, 2005
There is some controversy regarding whether vascular responses to endothelin are altered in hypercholesterolemia. Studies performed to date have been compromised by the use of endothelin antagonists at inappropriate concentrations.
