Tiny pressure sensor in artery measures blood pressure

High blood pressure can be a trial of patience for doctors and for sufferers, whose blood pressure often has to be monitored over a long time until it can be regulated. This will now be made easier by a pressure sensor that is inserted in the femoral artery.

Levels of two proteins impact survival in ovarian cancer

Levels of two proteins in a woman's ovarian cancer are strongly associated with her likelihood of survival, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Dec. 18 issue of the New England Journal of Medicine.

Integrated Children's System fails the children it was designed to protect

Just days after the head of Ofsted, Christine Gilbert, promised an overhaul of child protection inspection services in the wake of the death of Baby P, a new study claims that the IT-based procedures used by staff working at the 'front door' of local authority children's services could be putting the very children which they are designed to help at increased risk.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.

Ship-in-a-bottle kit on a microchip

Sometimes physicists resort to tried and trusted model-making tricks. Scientists at the Max Planck Institute for Metals Research, the University of Stuttgart and the Colorado School of Mines have constructed micromachines using the same trick that model makers use to get ships into a bottle where the masts and rigging of the sailing ship are not erected until it is in the bottle.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Discovery of key contributor to Alzheimer's disease process

Walter J. Lukiw, PhD, Associate Professor of Neuroscience and Ophthalmology at LSU Health Sciences Center New Orleans, is the lead author of a paper identifying, for the first time, a specific function of a fragment of ribonucleic acid (RNA), once thought to be no more than a byproduct, in regulating inflammation and the development of Alzheimer's disease.
