Peripheral Nerve Repair With Fat Precursor Cells Led To Wider Nerves And Less Muscle Atrophy
To determine if guided fat (adipose) precursor cells (APCs) could improve nerve regeneration and functional recovery, researchers at the University of Pittsburgh (USA) used biodegradable nerve guides to transplant APCs into the injured peripheral nerves of laboratory rats.

Removal Of Ban On Federal Funding For Needle Exchange Programs To Be Debated In Congress
An amendment to the fiscal year 2010 appropriations bill for health, labor and education programs that opposes the lifting of the ban on federal funding for needle exchange programs will come to the House floor for debate today along with four others, CQ Today reports. Rep. Mark Souder (R-Ind.) "will offer an amendment to strip language that would lift the ban on federal funding for needle exchange programs," CQ writes. According to CQ Today, "Conservatives are concerned that eliminating the ban on federal funds for such programs, which are designed to reduce the transmission of HIV and other diseases, would be tantamount to helping fund addicts" drug habits. Democrats say science has shown that such programs, when coupled with comprehensive prevention strategies, can reduce the rate of [HIV] infections and do not promote drug use." House Appropriations Committee Chair David Obey (D-Wis.) "added compromise language in the committee this week that would prohibit funds from going to needle exchange programs within 1,000 feet of facilities that serve children, such as schools and parks," the article states. The House is expected to vote on the amendment and the appropriations bill today (Wolfe, 7/23).

Bacteria Pack Their Own Demise
Numerous pathogens contain an "internal time bomb", a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. This clears the road for finding ways to set the clock on this internal time bomb and, hopefully, in the process developing a new class of antibiotics. The research was accepted for publication by top journal Molecular Cell, with congratulations from the editorial board.

Heatwave Advice For Diabetics

Experts are predicting record-breaking temperatures this week, so it"s important to take precautions to ensure that your diabetes remains well-controlled in this extreme weather. Long periods of inactivity in the sun can affect diabetes control, making blood glucose levels higher than usual. On the flipside, insulin will be absorbed more quickly from the injection site in hot weather and this increases the risk of hypos. Monitor your levels Cathy Moulton, Care Advisor at Diabetes UK, said: "People with diabetes will need to monitor their blood glucose levels more often and be ready to adjust their diet or insulin dose accordingly. "If your levels are higher than expected, it is worth considering whether your insulin could have been damaged in the sun." Top tips When you"re out and about in the sun, remember to: - wear long sleeves, loose trousers, a hat and sunglasses with a UV 400 label - apply sunscreen to exposed areas of your body 15-30 minutes before going out in the sun - If you have neuropathy you may not be aware when your feet are burning, so apply sunscreen and wear flip flops on hot ground. Heat exhaustion Heat exhaustion can develop when the body finds it difficult to keep cool. Symptoms include headaches, dizziness, nausea and vomiting, tiredness, muscle cramps, stomach cramps and pale skin. As some of these could also be due to unstable blood glucose levels, it"s important to test regularly. Cathy Moulton advised: "Heat exhaustion needs immediate treatment. Move to a cool place to rest and sip a cold drink. If left untreated heat exhaustion can lead to the more severe and potentially life-threatening condition heat stroke, so take action straight away." Symptoms of heat stroke include confusion, hallucinations, rapid breathing and convulsions, all of which require immediate medical attention. Be vigilant - "If people are vigilant about their diabetes control then there is no reason they can"t have fun in the sun like anybody else." Diabetes UK
