Female sex hormones play a vital role in defense against sexually transmitted diseases
Two McMaster University studies, to be published in the Journal of Virology, show that sex hormones have a profound effect on susceptibility of female mice to the herpes simplex virus, type 2 (HSV-2 ), one of the most common sexually transmitted diseases. Charu Kaushic, assistant professor and supervisor of the studies, says the implication of this work is quite significant. "The research...In the sea slug's defense against lobsters, confusion is key
Like many other marine creatures, Aplysia, a common sea slug, enlists chemical defenses against its predators, but the mechanisms by which such chemical attacks actually work against their intended targets are not well understood by researchers. New work has now shown that such chemical defenses can involve modes of trickery that had not previously been appreciated as components of chemical defen...Disease diagnosis, biodefense among UH chemical research projects
With 33 presentations of original research that showcase applications ranging from early-stage disease diagnosis to fuel cells and batteries, the University of Houston will be well represented at the 229th National Meeting of the American Chemical Society (ACS), March 13 to 17 in San Diego. Founded in 1876, the ACS is a nonprofit, scientific and educational organization and the largest sci...Defenseless plants arm themselves with metals
A group of plants that uses metal to defend against infection may do so because the normal defense mechanism used by most other plants is blocked. Purdue University researchers found that this group of plants produces, but does not respond to, the molecule that triggers the infection response used by nearly all other plants. The molecule does, however, allow this group of plants, called m...Comprehensive biodefense text published
A new book, Biological Weapons Defense: Infectious Disease and Counterbioterrorism, deals with the intentional causality of disease. Published by Humana Press, this text is also available in e-Book. Many of the contributors come from the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), the nation's premier biodefense laboratory. In this 624-page, hardcover text edite...Chippewa Valley Draws Defense Dollars
EAU CLAIRE, WI- Efforts at improving communication and technology in the battlefield could help to improve the economic outlook of the Chippewa Valley. Thanks in large part to efforts by Rep. Dave Obey (D-7th District), several Chippewa Falls-area companies are in line to receive defense contracts in the upcoming 2003 federal defense budget bill, which was passed by the House and the Sen...Small Tree Communications awarded $2.85M defense contract

exercise are crucial factors. But according to the research finding published by the American Journal of Preventive Medicine, // it has been found that calorie intake may not be a major factor in causing death by heart disease. The finding was based on a 17-year study of almost 9,790 Americans, who participated in the First National Health and Nutrition Examination Survey, a national st...Self-defense Mechanism of food borne bugs found
Professor Ray Dixon and his research team from Georgia Institute of Technology, US and the John Innes Center, UK have found a mechanism by which the pathogenic bacteria defends itself from the defense mechanism of the host. //The researchers have reported the results of their research in the Journal Nature. Pathogenic bacteria cause food borne illness by producing toxins in the food...Brain’s natural Antioxidant Defense Syste
The U.S. scientists have claimed that they have found the brain’s natural antioxidant defense mechanism to protect its nerve cells from toxic free radicals//. According to the researchers at the Dana-Farber Cancer Institute, this system protects the brain cells from the harmful effects of toxic ‘free radicals’ that are the waste products of cell metabolism that has been associated with...Newly Discovered Immune Defense May Be Impaired In CF Airways
A recent University of Iowa study reveals a new immune defense mechanism in normal airways and may help explain why people// with cystic fibrosis (CF) are particularly susceptible to bacterial lung infections. The findings also may point the way to new approaches for treating the disease. The UI study shows how two enzymes generate and use reactive oxygen species (ROS) to destroy bacte...Molecular ‘On/Off Switch’ Controls Immune Defenses Against Viruss
Much like flipping a light switch, the hepatitis C virus turns on human immune defenses upon entering the body //but also turns off those defenses by manipulating interaction of key cellular proteins, UT Southwestern Medical Center researchers have found. This same molecular “on/off switch” controls immunity against many viruses, highlighting a potential new target for novel therapeuti...
