New method to detect oxygen consumption in the brain

The human brain consumes an immense amount of energy and needs an uninterrupted supply of oxygen to maintain its activity. Therefore, the brain is equipped with a network of delicate blood vessels that transport oxygen molecules ...

Giving blood to artificial organs

Jelena Rnjak-Kovacina, and her team at the University of New South Wales and Tufts University in the USA, are using silk to grow blood vessels.

Cardiology

Heart valves strive to get oxygen one way or another

As the valves in a heart stretch with each beat, their cells take in life-giving oxygen. But if the supply is cut off, aortic and mitral valves use different strategies to compensate, according to Rice University scientists.

Implantable islet cells come with their own oxygen supply

Since the 1960s, researchers have been interested in the possibility of treating type 1 diabetes by transplanting islet cells—the pancreatic cells that are responsible for producing insulin when blood glucose concentration ...

Diabetes

Oxygen-tracking method could improve diabetes treatment

Transplanting pancreatic islet cells into patients with diabetes is a promising alternative to the daily insulin injections that many of these patients now require. These cells could act as a bioartificial pancreas, monitoring ...

Neuroscience

New non-invasive method for brain research

Neuroscientists at the University of Tübingen have become the first to record neuromagnetic activity in the millisecond-by-millisecond range while the brain of a human subject was under stimulation by electric current. Electric ...
