Many diseases arise from abnormalities in our capillaries, tiny exquisitely branching blood vessel networks that play a critical role in tissue health. Researchers have learned a lot about the ...

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 ...

In this book Sir Almroth Wright gives a full account of the ingenious apparatus and methods which he and his co-workers have evolved for making quantitative estimations, principally in connection with ...

The capillary tube is a very popular metering device used on many fractional horsepower refrigeration systems. It is basically a length of very small diameter copper tubing soldered or brazed between ...

As COVID-19 seems to be making a comeback in many areas of the world, including Japan, a new study published on the preprint server medRxiv* in October 2020 shows the relevance of microsamples 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 ...

Capillary tube metering devices are found mainly in domestic and small commercial applications that experience somewhat constant heat loads on their evaporators. These systems also have small ...

Going down: a droplet of honey in a superhydrophobic coated tube. (Courtesy: Aalto University) Honey and other highly viscous fluids can flow faster than water in specially coated capillary tubes.

Fill a narrow glass capillary tube with water, then turn it horizontal. Conventional wisdom says that the water will remain inside the tube. But a group of scientists in Spain and the UK has found ...

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 ...
