Surgeon General's report underscores the importance of new thinking on bone health

... the United States, 80 percent of them women. Bone deterioration is responsible for 1.5 million fractures each year, resulting in as many as 300,000 deaths due to complications, yet two simple measures--exercise and calcium--can help prevent it. Education and prevention are key themes in the report that also focus...

Biomedical engineers at case develop first sliver-sized sensor to monitor glucose levels

...s used. With no wires across the skin, there is no deterioration of the skin surface or other areas inside the skin and no danger of track infection. The device also is advantageous because no electrical currents are going through the body. Gratzl says lab testing and in vivo testing of the sensor in laboratory a...

The researchers give three possible reasons for the unexpected results. All of these reasons are derived from newer theories for the evolution of senescence that have ...

Promising results in the battle against incurable ALS muscle disease

...he originating mechanism of this deadly disease of deterioration - which has an enormous medico-social impact - remains obscure. At present, the disease is totally untreatable - causing many ALS patients to choose euthanasia, a very controversial solution. However, previous genetic research by Peter Carmeliet and ...

...and classic clinical features include memory loss, deterioration in speech, and behavioral disturbances. Doctors increasingly concede that central to the cause of AD is the production and accumulation of beta-amyloid (Abeta), which is toxic in the brain. There are only a few clinical therapeutic options for AD pat...
