USDA announces BSE test results and new BSE confirmatory testing protocol

Agriculture Secretary Mike Johanns today announced that the U.S. Department of Agriculture has received final test results from The Veterinary Laboratories Agency in Weybridge, England, confirming that a sample from an animal that was blocked from the food supply in November 2004 has tested positive for bovine spongiform encephalopathy (BSE). Johanns also directed USDA scientists to work with international experts to thoughtfully develop a new protocol that includes performing dual confirmatory tests in the event of another "inconclusive" BSE screening test. more  

The IHC test variables

IHC has been the primary confirmatory test for USDA’s BSE surveillance program and is recognized by the World Organization for Animal Health, or OIE. Several variables could yield conflicting results. IHC is not a standardized, commercially available test. It involves variables, including several options in types of antibodies and other reactive agents. The sensitivity of any given test is influenced by those variables. more

Researchers debut new X-ray resources for studying molecules

Soon scientists at Argonne National Laboratory near Chicago, Ill., will test-drive what many call the “Ferrari” of synchrotron beamlines — high-tech research facilities for imaging molecules. During a dedication ceremony on Monday, June 27, researchers will tour the facilities and watch experimental demonstrations on one of three new beamlines that promise to speed medical research. more  

Nation's first human case of West Nile in 2005 reported to CDC

The first human West Nile virus (WNV) illness of 2005 has been reported to the Centers for Disease Control and Prevention (CDC) by the Kansas Department of Health and Environment. WNV is transmitted seasonally by infected mosquitoes. Since 1999, when WNV was first identified in the United States, WNV has caused nearly 17,000 cases of human illness, including more than 650 deaths. more

Saving six million children each year is affordable 

Extra funding amounting to as little as US$1·23 per head in the 42 countries* with the highest rates of child mortality is needed to save 6million children, concludes a study published in this week’s issue of The Lancet. The cost is affordable for governments of even the poorest nations, if outside donors provide funds to build-up the health systems of these countries, state the authors. more

Postnatal depression in fathers may affect their children’s behavioral development 

Children whose fathers have had postnatal depression, have an increased risk of behavioural and emotional problems in early life, suggests a study published in this week’s issue of The Lancet. The researchers found the effect was the same even after they controlled for other factors that could influence a child’s development. more

CT predicts heart attack more accurately than Framingham, CRP

The St. Francis Heart Study, the largest long-term study of its kind, demonstrates that fast CT scanning of the coronary arteries predicts coronary events such as heart attack independently of and more accurately than conventional risk factors such as age, smoking, blood pressure and cholesterol, and C-reactive protein (CRP), a more recently identified risk factor. more
