Since Ddk is often deregulated in human cancers, this new understanding of its role in DNA damage control could help shape new cancer therapies. The research was published in the December 24 issue of Molecular Cell. http://www.physorg.com/news150397201.html Biology Mon, 05 Jan 2009 17:00:01 EST news150397201 Administering antibiotics as a preventive measure to patients in intensive care units (ICUs) increases their chances of survival.

It was the biggest outbreak of its kind in decades. http://www.physorg.com/news149346537.html Medicine & Health Wed, 24 Dec 2008 13:08:57 EST news149346537 Mast cells are now recognized as "granular cells of the connective tissue", whose activation exacerbates allergic immune responses and as key players in the establishment of innate immunity as well as modulators of adaptive immune responses. The role of mast cells in the gastrointestinal mucosa is not only to react to antigens, but also to actively regulate the barrier and transport properties of the intestinal epithelium. http://www.physorg.com/news149247749.html Medicine & Health Tue, 23 Dec 2008 09:42:29 EST news149247749 Researchers from Boston University School of Medicine (BUSM) have determined the optimal dose-management strategy to derive maximal benefit from warfarin therapy and improve patient outcomes. Results of the study appear online in the December 2008 issue of the Journal of Thrombosis and Haemostasis. http://www.physorg.com/news149168990.html Medicine & Health Mon, 22 Dec 2008 11:49:50 EST news149168990 When you first notice a door handle, your brain has already been hard at work. Your visual system first sees the handle, then it sends information to various parts of the brain, which go on to decipher out the details, such as color and the direction the handle is pointing. As the information about an object is sent further along the various brain pathways, more and more details are noticed -- in that way, a simple door handle turns into a silver-plated-antique-style-door-handle-facing-right. Information about the handle also reaches the part of your brain responsible for planning movements (known as the pre-motor area), and it comes up with a set of motions, allowing you to turn the handle with your right hand and open the door. http://www.physorg.com/news148828835.html Medicine & Health Thu, 18 Dec 2008 13:20:35 EST news148828835 Researchers at Thomas Jefferson University have found that a lower dose of fractionated stereotactic radiotherapy for acoustic neuromas results in better hearing preservation and has the same tumor local control rate as a higher dose of therapy. The study appeared online in the International Journal of Radiation Oncology*Biology*Physics. http://www.physorg.com/news148736594.html Medicine & Health Wed, 17 Dec 2008 11:43:14 EST news148736594 Persons with type 2 diabetes who had a diet high in low-glycemic foods such as nuts, beans and lentils had greater improvement in glycemic control and risk factors for coronary heart disease than persons on a diet with an emphasis on high-cereal fiber, according to a study in the December 17 issue of JAMA. http://www.physorg.com/news148709030.html Medicine & Health Wed, 17 Dec 2008 04:03:50 EST news148709030 Diversity is valuable socially, economically and now environmentally. Research by Michigan State University scientists has found that growing more corn to produce ethanol - creating less diverse landscapes - reduces the ability of beneficial insects to control pests, a loss valued at about $58 million per year in the four states studied (Michigan, Iowa, Minnesota and Wisconsin). http://www.physorg.com/news148583478.html Biology Mon, 15 Dec 2008 17:11:18 EST news148583478 Pharmaceutical companies and universities are racing to develop drugs that use the gene silencing mechanism known as RNA interference to treat a host of diseases. Now, a new study opens up an entirely new possibility for this powerful tool: Researchers at the University of Georgia have demonstrated for the first time that RNA interference can be used as a tool in the development of vaccines. http://www.physorg.com/news148148345.html Medicine & Health Wed, 10 Dec 2008 16:19:05 EST news148148345 Employees with high levels of job autonomy and control over their schedules are more likely to bring their work home with them, according to surprising new research out of the University of Toronto. http://www.physorg.com/news148132322.html Other Sciences Wed, 10 Dec 2008 11:52:02 EST news148132322 A preliminary study suggests that economic incentives appear to be effective for achieving short-term weight loss, according to a report in the December 10 issue of JAMA. http://www.physorg.com/news148067564.html Medicine & Health Tue, 09 Dec 2008 17:52:44 EST news148067564 (PhysOrg.com) -- Rejection is one of those universal experiences we can all relate to.

CD8+ T cells, which kill cells infected with HIV, enable LTNPs to control HIV, but it has been unclear how CD8+ T cells mediate that control so effectively. A new report shows that the ability to stockpile two molecular weapons makes the HIV-specific CD8+ T cells of LTNPs superior cellular killers. http://www.physorg.com/news147618212.html Medicine & Health Thu, 04 Dec 2008 13:03:32 EST news147618212 People who manage to control HIV on their own are providing scientists with valuable information about how the immune system eliminates virus-infected cells. A new study, published in the December 4th issue of Immunity, a Cell Press publication, identifies specific characteristics of the immune cells that successfully destroy HIV-infected cells and may drive strategies for developing the next generation of HIV vaccines and therapies. http://www.physorg.com/news147616847.html Medicine & Health Thu, 04 Dec 2008 12:40:47 EST news147616847 (PhysOrg.com) -- Software deadlocks are the Catch-22s of the computer world.
