EAST LANSING, Mich. — For his work on developing new treatments for tuberculosis, a Michigan State University researcher has been named a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation.

Robert Abramovitch of MSU’s Department of Microbiology and Molecular Genetics is using a synthetic biosensor that glows green in response to conditions that mimic human tuberculosis infection. He will screen for compounds that target chronic TB infection and may help shorten therapy or treat multidrug-resistant TB, which does not respond well to existing antibiotics. (more…)

Guidelines for Prostate Screening Widely Ignored, Study Finds

2008 recommendations from federal task force had no impact

New research confirms that the controversial decision by Warren Buffett – the 81-year-old CEO of Berkshire Hathaway – to undergo a blood test screening for prostate cancer despite his age is hardly unusual. Despite recommendations in 2008 from the United States Preventive Services Task Force against testing for prostate cancer in men aged 75 years or older, almost half of men in that age group continue to get screening tests.

In 2005, before the recommendations were released, 43 percent of men age 75 and above elected to take the prostate-specific antigen (PSA) test. In August 2008, the Task Force stated it “recommends against the service,” arguing “there is moderate or high certainty the service has no net benefit or that the harms outweigh the benefits.” (more…)

COLUMBUS, Ohio – Caring for a wife with breast cancer can have a measurable negative effect on men’s health, even years after the cancer diagnosis and completion of treatment, according to recent research.

Men who reported the highest levels of stress in relation to their wives’ cancer were at the highest risk for physical symptoms and weaker immune responses, the study showed. (more…)

*How Bob Vince changed the world*

Where does it begin, the act of becoming a scientist? Perhaps with a bowling ball, its finger holes packed with explosives, which when detonated, launch the ball into the air, cracking the otherwise pristine concrete walkway of your childhood home in four places, much to the consternation of your father. Or maybe with an explosion of homemade rocket fuel in your basement chemistry lab that scares your mother half to death. And all this before the troublesome teen years.

Bob Vince can’t be sure where his becoming a scientist began. But where it led changed the world. (more…)

AUSTIN, TX — A new form of proteins discovered by researchers at The University of Texas at Austin could drastically improve treatments for cancer and other diseases, as well as overcome some of the largest challenges in therapeutics: delivering drugs to patients safely, easily and more effectively.

The protein formulation strategy, discovered by chemical engineering faculty members and students in the Cockrell School of Engineering, is unprecedented and offers a new and universal approach to drug delivery — one that could revolutionize treatment of cancer, arthritis and infectious disease.

ANN ARBOR, Mich.— A non-invasive brain imaging technique gives new hope to patients with Parkinson’s disease in finding new and better treatment plans and tracking the disease progression, a new University of Michigan study shows.

The technique uses an MRI to measure resting state brain activity oscillations, said Rachael Seidler, associate professor in the School of Kinesiology and the Department of Psychology, and study author. (more…)

New CU Study Shows Acupressure Effective in Helping to Treat Traumatic Brain Injury

A new University of Colorado Boulder study indicates an ancient form of complementary medicine may be effective in helping to treat people with mild traumatic brain injury, a finding that may have implications for some U.S. war veterans returning home.

The study involved a treatment known as acupressure in which one’s fingertips are used to stimulate particular points on a person’s body — points similar to those stimulated with needles in standard acupuncture treatments, said CU-Boulder Professor Theresa Hernandez, lead study author. The results indicate a link between the acupressure treatments and enhanced cognitive function in study subjects with mild traumatic brain injury, or TBI. (more…)
