Magnetic resonance sees the heart beat
Ultrasound is commonly used to look at the heart, but it is unsuitable for the 10-20% of the population that have breathing difficulties (emphysema) or who are medically obese. In both techniques, pat...
Small melanin particles cause skin cancer
The radiation causes the eumelanin to generate large quantities of free oxygen radicals, which in turn damage cell DNA and hence may lead to cancer. His research was reported yesterday at the annual A...
Measuring the conductivity of blood
Doctors need to measure blood conductivity to calculate the internal pump volume of the heart and the blood circulation rate. However, when patients receive additional fluids – for example, wate...
Physics solves blood vessel mystery
Experiments on the effect have been performed by introducing a compound called angiotensin II into the blood stream of a rat. This compound narrows the diameter of the blood vessels, which increases t...
