1. Experts urge strongest isolation for new drug-resistant tuberculosis cases appearing in South Africa
   01-22-2007 · EurekAlert!
   Medical ethics and other experts say tough isolation measures, involuntary if need be, are justified to contain a very deadly, highly-contagious and drug-resistant mutant strains of tuberculosis and to prevent "a potentially explosive international health crisis" brewing most dangerously at the epicenter of South Africa's HIV/AIDS epidemic. The new TB variations now defeat many of the world's existing drugs and pose "extreme risk."

2. Waist-to-hip ratio may better predict cardiovascular risk than body mass index
   08-13-2007 · EurekAlert!
   A tape measure, not just a bathroom scale, may help you better assess your heart disease risk. In a study to be published in the Aug. 21 issue of the Journal of the American College of Cardiology, investigators at UT Southwestern Medical Center found that people with a larger waist-to-hip ratio may be at increased risk for heart disease. The research evaluates the association between different measures of obesity and the prevalence of arterial disease.

3. Kaiser Permanente -- Group Health study shows depression worsens HIV treatment
   12-20-2007 · EurekAlert!
   The largest study to examine the effect of depression on HIV treatment appears in the online edition of the Journal of Acquired Immune Deficiency Syndromes. The study by Kaiser Permanente and Group Health found depression significantly worsens a patient's adherence to highly active antiretroviral therapy and clinical measures but that effective antidepressant medication reverses this outcome. The study looked at 3,359 HIV-infected patients to measure the effects of depression -- with and without SSRIs.

6. Penn engineers create carbon nanopipettes that are smaller than cells and measure electric current
   01-15-2008 · EurekAlert!
   University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. Researchers developed this tiny carbon-based tool to probe cells with minimal intrusion and inject fluids without damaging or inhibiting cell growth.

8. NIST 'micro-rack' measures cell mechanical properties
   03-02-2007 · EurekAlert!
   Researchers at NIST have developed a microelectromechanical system (MEMS) cell-stretcher that can measure the mechanical properties of a living cell, such as its ability to stick to a surface. The new device is expected to enable novel studies of cell mechanics, which influence basic cell functions such as growth and division, and diseases such as sickle cell anemia and asthma.

10. New microsensor measures volatile organic compounds in water and air on-site
    09-17-2007 · EurekAlert!
    Researchers at the Georgia Institute of Technology have developed a miniature sensor that uses polymer membranes deposited on a tiny silicon disk to measure pollutants present in aqueous or gaseous environments. An array of these sensors with different surface coatings could be used during field-testing to rapidly detect many different chemicals.
