To explore the contribution of red blood cell (RBC) deformability and interaction with endothelial cells (ECs) to circulatory disorders, these RBC properties were modified by treatment with hydrogen peroxide (H(2)O(2)), and their effects on vascular ...

An increase in fetoplacental vascular resistance caused by hypoxia is considered one of the key factors of placental hypoperfusion and fetal undernutrition leading to intrauterine growth restriction (IUGR), one of the serious problems in current ...

Calculation of coronary vascular resistance
Cardiovascular Research, 1980A conscious, chronically instrumented canine model was used to investigate resistance changes in the distribution of the circumflex coronary artery as the artery was constricted. Several discrete constrictions were studied at two different levels of flow: resting and peak flow reactive hyperaemia.

Contribution of insulin resistance to vascular dysfunction
Archives of Physiology and Biochemistry, 2009Insulin is a vascular hormone, able to influence vascular cell responses. In this review, we consider the insulin actions on vascular endothelium and on vascular smooth muscle cells (VSMC) both in physiological conditions and in the presence of insulin resistance.

Assessment of operability of congenital cardiac shunts with increased pulmonary vascular resistance
Catheterization and cardiovascular interventions, 2008Patients with large left to right shunts as a result of congenital heart disease can develop changes in pulmonary vasculature that are initially reversible. It is critical in these patients to determine whether closure of the defect would reverse some of

Hematocrit-corrected Pulmonary Vascular Resistance
American Journal of Respiratory and Critical Care Medicine, 2018The diagnosis and evaluation of severity of pulmonary vascular disease rests on the invasive determination of a pulmonary vascular resistance (PVR). It is often overlooked that PVR is linearly related to the viscosity of the blood, which in turn is curvilinearly related to hematocrit.

The height of the systemic vascular resistance is largely dependent on the total cross-sectional area of the arterioles in the peripheral vasculature. The smooth muscle tone of these vessels is influenced by neural, humoral, and local environmental factors.

Neurohumoral Control of Vascular Resistance
Archives of Internal Medicine, 1974The precise role of neurogenic and humoral mechanisms in the pathogenesis of hypertension cannot be defined. Most likely several mechanisms are interacting. These may differ in the early phases of hypertension if trigger mechanisms are involved and in later phases of sustained hypertension if adaptive changes create a situation of hyperresponsiveness ...

Reflex increase in coronary vascular resistance in patients with ischemic heart disease.
New England Journal of Medicine, 1976To assess possible coronary vasoconstriction in patients with ischemic heart disease, we measured coronary vascular resistance in 12 patients with normal hearts and 12 with coronary disease before and during the initial 50 seconds of cold pressor test, a
