Purdue researchers have identified a new class of chemical insecticides that could provide a safer, more selective means of controlling mosquitoes that transmit key infectious diseases such as dengue, yellow fever and elephantiasis. https://phys.org/news/2015-04-class-insecticides-safer-mosquito.html Cell & Microbiology Wed, 01 Apr 2015 16:30:52 EDT news347124643 New research reveals a strategy for disrupting the ability of bacteria to communicate and coordinate the expression of virulence factors. The study, published by Cell Press in the April 22nd issue of the journal Molecular Cell, may lead to the development of new antibacterial therapeutics. https://phys.org/news/2011-04-bacteria-disabling-behavior-virulence-gene.html Cell & Microbiology Thu, 21 Apr 2011 13:01:00 EDT news222609648 (PhysOrg.com) -- When reactive oxygen species (ROS) hit the body, vitamin E helps to prevent damage to tissues and cells by acting as an antioxidant. The health benefits of vitamin E are numerous, and in fact, studies have found that people with higher levels of vitamin E in their system have a lower risk of heart disease and certain forms of cancer. A team led by Thomas Rosenau from the University of Natural Resources and Life Sciences in Vienna (Austria) now describe their synthesis of a series of modified vitamin E derivatives that show promise as dioxin receptor antagonists in the European Journal of Organic Chemistry. https://phys.org/news/2011-03-vitamins-tocopherol-derivatives-dioxin-receptor.html Biochemistry Fri, 18 Mar 2011 09:21:36 EDT news219658832
