Mild vibrations may provide exercise-like benefits for obese

Summary:
If you're looking to get some of the benefits of exercise without doing the work, here's some good news. A new research report shows that low-intensity vibrations led to improvements in the immune function of obese mice. If the same effect can be found in people, this could have clinical benefits for obese people suffering from a wide range of immune problems related to obesity.

If you're looking to get some of the benefits of exercise without doing the work, here's some good news. A new research report published online in The FASEB Journal shows that low-intensity vibrations led to improvements in the immune function of obese mice. If the same effect can be found in people, this could have clinical benefits for obese people suffering from a wide range of immune problems related to obesity.

"This study demonstrates that mechanical signals can help restore an immune system compromised by obesity," said Clinton Rubin, Ph.D., study author from the Department of Biomedical Engineering at Stony Brook University in Stony Brook, New York. "While it is well known that obesity can cripple many physiologic systems, this work suggests that mechanical signals -- in the absence of drugs -- can help combat this disease and its sequelae. That these mechanical signals are so brief, and so mild, is further evidence of how exquisitely tuned our body is to external signals, and that remaining active -- climbing stairs at work, taking a walk at lunch, standing while reading a book -- will help achieve and retain good health. Stand up!"

To make this discovery, Rubin and colleagues fed a group of adult mice a high fat diet for seven months to make them obese. At the end of this first phase of the experiment, the damage to the immune and skeletal systems of the obese mice was significant, decreasing B- and T-cell populations in the blood, and markedly accelerating the loss of bone. The second phase began after the mice were obese relative to regular controls, with the creation of a sub-group that was subjected to daily 15-minute bouts of low-intensity vibration, barely perceptible to human touch. Results showed that the vibration intervention helped to rescue both the immune and skeletal systems, returning them toward outcomes measured in mice that were fed a regular diet. This study provides evidence that obesity markedly reduces the production of B- and T-cells and that brief daily exposure to low magnitude mechanical signals rescues B- and T-cell populations, even in a mouse that is already obese.

"This solid support for a shaky intervention should get scientists and health care professionals buzzing," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "If it works out in people, low intensity vibration could be a relatively cheap way of helping obese folks regain health without drugs -- until they lose weight by diet and exercise."

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
