THE measurement of the packed red-cell volume (or hematocrit) of the venous blood has long been recognized as a useful aid in the study of blood in a large number of clinical conditions. The technic ...

Engineered human capillaries are providing an astounding view of how red blood cells transit ultra-small blood vessels. This new platform was used in a recent study to learn how severe malaria ...

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 ...

Capillary leak syndrome is a rare disorder where the plasma in your blood leaks from your capillaries (small blood vessels) into surrounding tissues in your body. It affects fewer than 1,000 people in ...

Thanks to the increasing availability of point-of-care (POC) testing, the use of capillary blood (fingerstick) sampling worldwide is growing. Anemia affects around 25% of the global population. Its ...

Background: Studies measuring human growth hormone (hGH) in blood during exercise have mainly used venous sampling. The invasive nature of this procedure makes evaluation of hGH impossible in various ...

New research has uncovered that capillaries have the capacity to both sense brain activity and generate an electrical vasodilatory signal to evoke blood flow and direct nutrients to neurons. All it ...
