AN important feature of the peripheral circulation is the close correspondence between the local needs of a given tissue and the amount of blood supplying it. Controlling mechanisms, to accomplish ...

WHILE it is obvious that the capillary circulation is subject to local physiological control, there is much difference of opinion as to how this is achieved. In particular, it is still undecided ...

This is a preview. Log in through your library . Abstract Analysis of the spatiotemporal coupling between neuronal activity and cerebral blood flow requires the precise measurement of the dynamics of ...

New research on tiny capillaries and cells called pericytes details how blood moves through over 400 miles of total vasculature in the human brain. While the human brain has over 400 miles of total ...

The brain is perhaps the most sensitive organ with respect to changes in blood flow and oxygen supply. Even brief interruptions in capillary flow (or "stalling") can indicate acute neurological issues ...

When you sit quietly for a moment listening to your heart pump blood through your body, do you think about blood vessels as a firehose drenching your organs and brain with red blood cells full of ...

All it takes is the flip of a protein "switch" within the tiny wire-like capillaries of the brain to increase the blood flow that ensures optimal brain function. New research has uncovered that ...

Sublingual nitroglycerin reduced pulmonary capillary wedge pressure in patients with HF with preserved ejection fraction during exercise, but did not improve oxygen uptake or cardiac output, according ...

IN modern civilizations an enormous toll of suffering and death is exacted by local disorders of brain blood flow. Regional hemodynamic failure, with unique rapidity, produces anoxic devastation in ...

3D microvessels have been created to observe how red blood cells transit ultra-small blood vessels. They squeeze single-file through microvessels to bring oxygen and nutrients. Red cells burdened with ...
