Renal Vascular Resistance in Sepsis
Nephron Physiology, 2006<i>Aims:</i> To assess changes in renal vascular resistance (RVR) in human and experimental sepsis and to identify determinants of RVR. <i>Methods:</i> We performed a systematic interrogation of two electronic reference libraries using specific search terms.

Peripheral pulmonary vascular resistance
Journal of Applied Physiology, 1993The pressure-flow relationship has been studied in a peripheral portion of the lung vasculature in anesthetized dogs with use of a double-lumen catheter wedged in a distal pulmonary artery. One lumen was used to infuse mixed venous blood in the wedged area and the other to measure the corresponding perfusion pressure. Flow ranged from 0 to 9.2 ml/min,

Insulin resistance and vascular function
Journal of Diabetes and its Complications, 2002It has become clear that amongst its many actions insulin is also a vasoactive hormone. Its effect to cause endothelial-nitric oxide-dependent vasodilation is physiologic and dose-dependent. Recent data suggest that insulin's metabolic and vascular actions are closely linked.

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.

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.

Resistance to vascular wilt parasites
Netherlands Journal of Plant Pathology, 1968When tomato plants resistant toVerticillium albo-atrum become infected with this fungus the parasite grows very little in the stem. The stem, however, responds by producing many tyloses. In susceptible tomato plants in which the parasite is more abundant few tyloses occur, but after some weeks when the parasite begins to disappear from the lower parts ...

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 ...
