New study: Free radicals play a key role in heart physiology

Fear of free radicals may be exaggerated, according to scientists from the Swedish medical university Karolinska Institutet. A new study, published in The Journal of Physiology, shows that free radicals act as signal substances that cause the heart to beat with the correct force.

Study: Fish oil may prevent muscle and weight loss in cancer patients during chemotherapy

A new analysis has found that supplementing the diet with fish oil may prevent muscle and weight loss that commonly occurs in cancer patients who undergo chemotherapy. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates that fish oil may help combat cancer-related malnutrition.

U.S.-Chile collaborate to study new long-acting local anesthetic derived from algae

A U.S.-Chile collaboration is bringing surgical patients closer to having a long-acting local anesthetic. In a randomized, double-blind trial, patients given neosaxitoxin, a new local anesthetic derived from algae, had significantly less postoperative pain and recovered about two days sooner than those given the commonly used local anesthetic bupivacaine.

Meditation leads to stronger mind-body connection than dancing

The body is a dancer's instrument, but is it attuned to the mind? A new study from the University of California, Berkeley, suggests that professional ballet and modern dancers are not as emotionally in sync with their bodies as are people who regularly practice meditation.

Progeria-derived iPS cells may treat aging-related disease in children

The current pace of population aging is without parallel in human history but surprisingly little is known about the human aging process, because lifespans of eight decades or more make it difficult to study. Now, researchers at the Salk Institute for Biological Studies have replicated premature aging in the lab, allowing them to study aging-related disease in a dish.

Versatile ultra-low power biomedical signal processor

At today’s International Solid-State Circuit Conference (ISSCC2011), imec, Holst Centre and NXP present a versatile ultra-low power biomedical signal processor, CoolBioTM, meeting the requirements of future wearable biomedical sensor systems. The biomedical signal processor consumes only 13pJ/cycle when running a complex ECG (electrocardiogram) algorithm at 1MHz and 0.4V operating voltage. This C-programmable chip is voltage and performance scalable supporting a frequency range of 1MHz up to 100MHz with an operating voltage from 0.4 to 1.2V.

Mutated cancer pathway studies identify therapeutic targets for congenital heart disease

Cross-disciplinary teams of scientists studying genetic pathways that are mutated in many forms of cancer, but which also cause certain forms of congenital heart disease - including hypertrophic cardiomyopathy, a thickening of the heart muscle that is the leading cause of sudden death in children and young adults -, have introduced these mutations into mice and successfully treated HCM in the lab.

Amphetamine linked to development of Parkinson’s disease

New research suggests that taking prescription amphetamines may raise the risk of developing Parkinson’s disease later. But, the researchers noted that the study did not prove a cause-and-effect relationship and further investigation is warranted. The research was released Feb. 19, and is scheduled to be presented in April at the American Academy of Neurology’s annual meeting in Honolulu.
