The heart powers a busy highway of arteries and vessels, providing a constant to-and-fro passage for blood. During a heart ...

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 ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Researchers discover that capillary obstruction in diabetes, triggered by elevated interleukin-10 signaling, may contribute to cognitive deficits independent of blood sugar levels. Study: A pathogenic ...

The capillary tubes are made for neonates. In neonates, capillary blood samples are desirable over other forms of sampling. This is because frequent blood collection from patients with low blood ...

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 ...

Scientists combine Bessel beam two-photon microscopy with high throughput analysis for faster and more precise measurements of blood flow The brain is perhaps the most sensitive organ with respect to ...
