TR BioSurgical, LLC Develops Breakthrough Osteoarthritis Implant
TR BioSurgical, LLC, announced highly encouraging results using their new medical device (bioscaffold) in canine patients with advanced osteoarthritis. The new bioscaffold is implanted in or near diseased tissue and provides a structural matrix for local repair cells, such as stem cells or fibroblasts, to attach and heal tissue by local, physiological repair mechanisms. The new bioscaffold implant contains no drugs, cells or growth factors and is eventually resorbed by the infiltrating cells. The implant is made from a proprietary, copolymerized collagen and is sterile, cost effective, and non- immunogenic.

Study Looks At HIV, Risk Behaviors Among Male Clients Of Sex Workers In Tijuana, Mexico
"A large percentage" of U.S. and Mexican men who regularly engage in sexual activity with sex workers in Tijuana, Mexico, do not use condoms and have a history of substance and alcohol use, according to a study published in the online journal AIDS, the Los Angeles Times" blog "L.A. Now" reports. The study, by researchers from Mexico and the University of California-San Diego, surveyed 400 men - both Mexico and U.S. residents - and found that half of the men had unprotected sex with a female sex worker within the last four months. Researchers noted that although Tijuana authorities require that sex workers be registered and tested regularly for HIV, "only about half of [sex workers] have registered or been tested," according to the blog. Thomas Patterson of the UC-San Diego"s department of psychiatry and the Veterans Affairs health center, said the findings indicate a need for an educational campaign targeting men who frequent sex workers (Perry, 7/11).

Hoyer Objects To Medicare Cost Control Plan
House Majority Leader Steny Hoyer, D-Md., said he disagrees with President Obama"s support of transferring Congress"s price-setting powers over Medicare to the Medicare Payment Advisory Commission (MedPAC), which now acts as an advisory panel, USA Today reports. In a letter to senators Wednesday, Obama floated support for the idea: "Under this approach, MedPAC"s recommendations on cost reductions would be adopted unless opposed by a joint resolution of the Congress."

Real-Time Observation Of Queensland's Drinking Water

CSIRO and a local water authority in Queensland, SEQWater, have joined forces to monitor the Lake Wivenhoe catchment, which spans an area about the size of the city of Brisbane, and supplies water to the region"s 1.5 million residents. Approximately 120 nodes, using CSIRO"s FLECK™ smart wireless sensor network technology, are monitoring environmental conditions on Lake Wivenhoe and in the surrounding catchment. CSIRO Senior Research Scientist, Dr Matthew Dunbabin said it is hoped that these sensors can provide the platform for the next generation of water quality monitoring systems. "This is about real time data collection from the storage to the shore with a level of speed and detail not seen before," Dr Dunbabin said. The sensor nodes operate in a meshed network, which means they record environmental variables and cooperate with each other to set up an ad hoc network to wirelessly transfer data. "This gives us the capacity to monitor "events" in real-time, such as high rainfall, droughts or contaminants entering the waterway," Dr Dunbabin said. "If the network detects an "event", it can autonomously advise the boat to sample in more detail." Seqwater principal scientist, Associate Professor James Udy said the network is a cost-effective way of integrating different measures such as water quality, event flows, weather and pasture conditions, as well as cow movement. Of the 120 nodes, 45 are floating and measure water temperature through the water column, while another 70 are land-based and spread across the catchment. An autonomous solar-powered catamaran travels between the floating nodes gathering data. Developed by CSIRO, this is manually controlled through a PDA, web interface or web-enabled mobile phones.
