Oxidized CaMKII may increase risk of death in diabetics following heart attack

Having diabetes doubles a person's risk of dying after a heart attack, but the reason for the increased risk is not clear. A new University of Iowa study suggests the link may lie in the over-activation of an important heart enzyme, which leads to death of pacemaker cells in the heart, abnormal heart rhythm, and increased risk of sudden death in diabetic mice following a heart attack.

Infrared signaling could create sense of touch in artificial limbs

Rats can't usually see infrared light, but they have "touched" it in a Duke University lab. The rats sensed the light as a sensation of touch after Duke neurobiologist Miguel Nicolelis and his team fitted the animals with an infrared detector wired to electrodes implanted in the part of the mammalian brain that processes information related to the sense of touch.

Researchers identify mechanism through which mitochondria control breast tumor aggressiveness

Doctors currently struggle to determine whether a breast tumor is likely to shift into an aggressive, life-threatening mode-an issue with profound implications for treatment. Now a group from The Scripps Research Institute (TSRI) has identified a mechanism through which mitochondria, the powerhouses of a cell, control tumor aggressiveness.

Prions may be crucial in brain development during childhood

A molecule that is not only dangerous, but can help the brain grow. A few years ago it was found that certain proteins, the prions, when defective are dangerous, as they are involved in neurodegenerative syndromes such as the Creutzfeldt-Jakob and the Alzheimer diseases.

Canine Pompe disease can now be diagnosed with genetic test

Pompe disease, a severe glycogen storage disease appearing in Lapphunds is caused by a genetic defect in acid α-glucosidase gene. The same genetic mutation also causes the equivalent disease in humans. Based on this finding, canine Pompe disease can now be diagnosed with a genetic test.

New insights into how cells stick to each other and to other bodily structures

Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer.
