Embryo Movement Stimulates Joint Formation
A new study uncovers a molecular mechanism that explains why joints fail to develop in embryos with paralyzed limbs. The research, published by Cell Press in the May issue of the journal Developmental Cell, answers a longstanding question about the influence of muscle activity on developing joints and underscores the critical contribution of movement to regulation of a signaling pathway that is important during development and beyond.

Salsa Or Tango Toward Health
Ballroom dancing has gained in popularity in recent years as an activity for health and fitness. According to research presented today at the American College of Sports Medicine (ACSM) 56th Annual Meeting in Seattle, ballroom dances like the salsa and the tango contribute to health gains and may improve fitness for amateur adult dancers, as measured by heart rates and energy expenditure.

Mammograms Not Improved By A Break From Hormone Therapy
Some women take a short break from using postmenopausal hormone therapy before getting their breasts screened for cancer with mammography. They hope to lower their risk of being called back afterward for unnecessary extra breast imaging. But taking a short break from hormones doesn"t actually work for this purpose, according to the first large-scale randomized controlled trial to address the question. The READ (Radiological Evaluation and Breast Density) trial of more than 1,700 Group Health women is in the June 2, 2009 Annals of Internal Medicine.

Osmetech Submits Swine Flu Test To The FDA

Osmetech (LSE:OMH) announced that it has submitted a request to the US FDA for Emergency Use Authorization (EUA) for its Respiratory Pathogen Test Panel test to be used to screen for the swine flu virus. Osmetech"s Respiratory Pathogen Test Panel test, which is expected to be launched as a research use only (RUO) product next quarter, detects and differentiates between 18 common bacterial and viral infections, including the Influenza A virus and its H1N1 subtype. Osmetech is currently developing an extension to the Respiratory Pathogen Test that will differentiate this H1N1 subtype between the human and swine forms of the virus. Osmetech Respiratory Pathogen Test Panel test has been adapted from QIAGEN"s QIAplex-based respiratory viral test for use on Osmetech"s eSensor XT-8 molecular diagnostics system, under the terms of an agreement signed in September 2008. James White, Chief Executive, Osmetech plc, said: "We believe that our test is ideally suited for fast and reliable screening of Influenza A virus types, including the swine flu strain which is currently a major pandemic concern. The test will be run on our eSensor XT-8 platform, which is a small, portable and easy to use platform that has the potential to enable testing to occur in numerous locations." About Swine Flu Swine flu (swine influenza) is a highly contagious respiratory disease of pigs, caused by one of several swine influenza A viruses. Since pigs can be infected with more than one virus type at a time, genes of several viruses from various s (including humans) can mix, allowing the swine influenza viruses to cross species barrier and eventually cause disease in humans. The clinical symptoms then are similar to seasonal influenza and other acute upper respiratory tract infections, in some cases leading to severe pneumonia and resulting in death. However, since mild or asymptomatic cases may have escaped from recognition, the true extent of this disease among humans is still unknown. Currently, there is no human vaccine on the market which protects against swine influenza. Antiviral drugs are available in many countries.
