Arterial Vasodilatation and Renal Vasoconstriction in Patients with Sepsis. Endotoxemia stimulates the induction of nitric oxide synthase, which leads to nitric oxide–mediated arterial ...

The steps involved in vasoconstriction are shown in blue, and the steps involved in vasodilatation are shown in red. The phosphorylation (P) of myosin is the critical step in the contraction of ...

Hepatorenal syndrome (HRS) is a serious complication of advanced cirrhosis with ascites. HRS develops as a result of abnormal haemodynamics, leading to splanchnic and systemic vasodilatation, but ...

The cold-induced vascular response, consisting of vasoconstriction followed by vasodilatation, is critical for protecting the cutaneous tissues against cold injury. Whilst this physiological ...

Vasoconstriction is a normal and complex process where blood vessels in your body narrow, restricting blood flow from an area. We discuss what’s happening and why it’s normal, what causes ...

The physiological response to hypovolemia is vasoconstriction, which diverts blood to the central circulation. ... malaria or anesthesia, which all tend to cause vasodilatation.

Vasodilation is a natural process that happens in your body. In some situations it can be harmful, yet in others causing vasodilation is important treatment for a condition. We unpack the good and ...

Vasodilation refers to a widening of the body’s blood vessels. In this article, learn about what causes vasodilation and how it can affect a person’s health.

Figure 1. An overview of the pathogenesis of migraine headache. According to vascular theory, vascular disturbances (vasodilatation–vasoconstriction) lead to migraine attacks through a cascade ...

Objective: To test the hypothesis that enhanced postexercise vasodilatation is related to sympathetic drive to resistance vessels and to fast marathon performance. Design: Prospective field study ...
