Brain works best when cells keep right rhythms

It is said that each of us marches to the beat of a different drum, but new Stanford University research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning.

Better targeting of stem cells as medication

Up till now it has not been possible to control stem cells in such a way that they grow into new blood vessels outside the body, or - when injected into an organ - lead to the creation of new small blood vessels and tissue repair.

High blood pressure, diabetes and increased carotid artery wall thickness means increased risk of stroke

Increased carotid artery wall thickness (CAWT), which can cause heart attack and stroke in many patients, is significantly related to diabetes and hypertension, according to a study performed at A.O.U. in Cagliari Sardegna, Italy (Chairman, Professor Giorgio Mallarini).

Even modest exercise improves insulin sensitivity, decreases fat in the liver and inflammation in belly fat

A new University of Illinois study suggests that moderate amounts of exercise alone can reduce the inflammation in visceral fat - belly fat, if you will - that has been linked with metabolic syndrome, a group of risk factors that predict heart disease and Type 2 diabetes.

In-body stem cell therapy has enormous potential for bone injuries

Rarely will physicians use the word "miraculous" when discussing patient recoveries. But that's the very phrase orthopaedic physicians and scientists are using in upstate New York to describe their emerging stem cell research that could have a profound impact on the treatment of bone injuries. Results from preliminary work being released today, patients confined to wheelchairs were able to walk or live independently again because their broken bones finally healed.

Double-lung transplants work better than single for long-term survival

Having both lungs replaced instead of just one is the single most important feature determining who lives longest after having a lung transplant, more than doubling an organ recipient's chances of extending their life by over a decade, a study by a team of transplant surgeons at Johns Hopkins shows.
