A drawback for the use of stem cells in medical treatment is their limited supply due to slow rate of growth in conventional laboratories. Dr Abba Zubair of the Cell Therapy Laboratory at Mayo Clinic in Florida believes this problem could be overcome and stem cell generation sped up by conducting the process in space. He will now have the opportunity to put his hypothesis to the test, courtesy of a US$30,000 grant that will see Zubair send human stem cells to the International Space Station (ISS) to observe whether they do in fact grow at a greater rate than on terra firma.  Read More

Although computer-controlled artificial legs have been around for a few years now, they generally still feature an ankle joint that only allows the foot to tilt along a toe-up/toe-down axis. That's fine for walking in a straight line, but what happens when users want to turn a corner, or walk over uneven terrain? Well, in some cases, they end up falling down. That's why researchers at Michigan Technological University are now developing a microprocessor-controlled leg with an ankle that also lets the foot roll from side to side.  Read More

A new device known as NIRS uses light to non-invasively monitor blood oxygenation in the b...

Approximately one third of stroke patients experience another stroke while they’re still in the hospital. Nurses therefore keep a close eye on them, and arrange for them to be taken for tests if a subsequent stroke is suspected. Unfortunately these tests can be invasive, and in some cases are even potentially harmful to the patient. A new device being developed at the Mayo Clinic in Florida, however, could watch for strokes simply by shining light onto a patient’s forehead.  Read More

If a just-announced research project is successful, then maybe – just maybe – diabetics will finally be free of having to perform daily finger prick blood tests and insulin injections. Based on new findings regarding the body’s production of insulin, Mayo Clinic endocrinologists Yogish Kudva and Ananda Basu are in the process of developing an artificial pancreas, that would automatically deliver the hormone when needed.  Read More

Using a virus containing a ‘library’ of DNA, researchers from the University of Leeds in the U.K., working with the Mayo Clinic in the U.S., have developed a vaccine that was able to destroy prostate cancer tumors in mice, while leaving healthy tissue untouched. Because the virus contains multiple fragments of genes, the vaccine is able to produce many possible antigens thereby boosting its effectiveness. The technique could be used to create vaccines to treat a wide range of cancers, including breast, pancreatic and lung tumors.  Read More

Obesity rates are on the rise in most western countries where sitting at a computer all day (and sometimes into the night) is commonplace. Low activity levels, in many cases, combined with poor diets, have been blamed for almost two-thirds of Americans being overweight or obese. To help address the problem, health researchers have developed an iPhone app designed to monitor your physical activity and motivate you to do that little bit more.  Read More

The key to Obesity? Mayo researchers find mechanism that adjusts fat burning

Mayo researchers collaborating with investigators at the University of Iowa, University of Connecticut and New York University (NYU) have discovered a molecular mechanism that controls energy expenditure in muscles and helps determine body weight. Researchers say this could lead to a new medical approach in treating obesity. The findings appear in the journal Cell Metabolism.  Read More

Dr. James Levine on his Walk-At-Work treadmill

May 22, 2007 Sitting still at a desk all day - like you're probably doing right now - is making the average office worker fatter and less healthy than we've ever been before. Gym workouts and regular exercise are not the key to breaking out of this cycle - a new study suggests that it's the sitting down that's killing us, and that a simple change to spending 2-3 hours a day gently walking at around 1mph while we work could help obese office workers lose up to 30kg a year. Dr. James Levine devised the walk-at-work treadmill to test the effectiveness of getting office workers off their butts - with fantastic results.  Read More

Hospital Equipment Unaffected By Cell Phone Use, Study Finds

March 12, 2007 Although cellular telephone use has been prohibited in hospitals because of concerns of interference with medical devices, a new study by Mayo Clinic researchers shows that calls made on cellular phones have no negative impact on hospital medical devices, dispelling the long-held notion that they are unsafe to use in health care facilities. Three hundred tests were performed over a five-month period in 2006 using two cellular phones, which used different technologies from different carriers and 192 medical devices. Not a single problem was found. The study's authors say the findings should prompt hospitals to alter or abandon their bans on cell phone use.  Read More

Mayo Clinic Health software for mobile phones

February 23, 2007 Mayo Clinic and Digital Cyclone (a subsidiary of Garmin) have collaborated to develop a software application that delivers an array of health information and tools directly to cellular phones. The Mayo Clinic InTouch wireless health program will be available next week offering wireless phone subscribers a rich health resource directly on their phone with immediate access to step-by-step first aid tips, a symptom checker that provides self-care guidelines or advises emergency care for more than 45 common symptoms in adults and children, health news videos, health alerts and drug watches.  Read More
