With flu season in full swing and the threat of H1N1 looming, demand for vaccines is at an all-time high. Although those vaccines are expected to be effective, University of Missouri researchers have found further evidence that some over-the-counter drugs, such as aspirin and Tylenol, that inhibit certain enzymes could impact the effectiveness of vaccines. http://www.physorg.com/news178902940.html Medicine & Health Tue, 01 Dec 2009 15:30:01 EST news178902940 (PhysOrg.com) -- With flu vaccination season in full swing, research from the University of Rochester Medical Center cautions that use of many common pain killers - Advil, Tylenol, aspirin - at the time of injection may blunt the effect of the shot and have a negative effect on the immune system. http://www.physorg.com/news176466143.html Medicine & Health Tue, 03 Nov 2009 10:50:01 EST news176466143 Helicobacter pylori has been accepted as an important pathogen inducing gastric cancer. A research group from Taiwan investigated optimal intervention point of Celecoxib, to inhibit H. pylori-associated gastric carcinogenesis in Mongolian gerbils. They found that short-term use resulted in less severe inflammation and inhibited the invasion degree of gastric cancer. Therefore, Celecoxib could be used in the later stages of H. pylori infection to achieve safe and effective chemoprevention of gastric adenocarcinoma. http://www.physorg.com/news175957992.html Medicine & Health Wed, 28 Oct 2009 19:20:02 EST news175957992 It is common practice to insert totally implantable venous access devices (TIVADs) in cancer patients beginning a course of chemotherapy to eliminate potential peripheral venous access problems; however, risk factors impacting the survival of TIVADs remain unclear. Further studies are needed to analyze the risk factors for failure of the TIVADs and correlate adverse events with risk factors. http://www.physorg.com/news175166576.html Medicine & Health Mon, 19 Oct 2009 10:23:41 EST news175166576 Men and women who were diagnosed with colorectal cancer and began regular use of aspirin had a lower risk of overall and colorectal cancer death compared to patients not using aspirin, according to a study in the August 12 issue of JAMA. http://www.physorg.com/news169225524.html Medicine & Health Tue, 11 Aug 2009 16:06:46 EST news169225524 Two forms of skin and brain cancer respond very poorly to chemotherapy and radiation: melanoma and glioblastoma multiforme brain cancer. http://www.physorg.com/news168706119.html Medicine & Health Wed, 05 Aug 2009 16:10:02 EST news168706119 A new study finds that individuals who have low expression of the "Celebrex gene," 15-PGDH, are actually resistant to Celebrex treatment when used to prevent colon cancer. The study, published in this week's issue of the Proceedings of the National Academy of Sciences (PNAS), is by Sanford Markowitz, M.D., Ph.D., the Markowitz-Ingalls Professor of Cancer Genetics at the Case Western Reserve University School of Medicine and an oncologist at the Ireland Cancer Center of University Hospitals Case Medical Center and his colleagues. http://www.physorg.com/news161886111.html Medicine & Health Mon, 18 May 2009 17:22:30 EST news161886111 Researchers at the University of Southern California have identified a new drug compound that appears to target tumor cells and surrounding blood vessels without the negative side effects typically associated with Cox-2 inhibitors. http://www.physorg.com/news159439792.html Medicine & Health Mon, 20 Apr 2009 09:50:24 EST news159439792 Omega-3 fatty acids appear protective against advanced prostate cancer, and this effect may be modified by a genetic variant in the COX-2 gene, according to a report in Clinical Cancer Research, a journal of the American Association for Cancer Research. http://www.physorg.com/news157127313.html Medicine & Health Tue, 24 Mar 2009 15:31:23 EST news157127313 A chemical component of licorice may offer a new approach to preventing colorectal cancer without the adverse side effects of other preventive therapies, Vanderbilt University Medical Center researchers report. http://www.physorg.com/news157047274.html Medicine & Health Mon, 23 Mar 2009 17:16:48 EST news157047274 Researchers have unraveled crucial details of how aging causes broken bones to heal slowly, or not at all, according to study results published today in the Journal of Bone and Mineral Research. The research team also successfully conducted preclinical tests on a potential new class of treatments designed to "rescue" healing capability lost to aging. http://www.physorg.com/news151241371.html Medicine & Health Thu, 15 Jan 2009 11:29:31 EST news151241371 Despite considerable progress in modern chemotherapy, there remains a large demand for innovative anti-tumor agents. A new approach involves modeling the pharmacological properties of established drugs with organometallic fragments. As a team of scientists from Berlin and Bochum (Germany), Innsbruck (Austria), and Leiden (The Netherlands) report in the journal Angewandte Chemie, cobalt-aspirin complexes have potential as cytostatics. http://www.physorg.com/news151046764.html Chemistry Tue, 13 Jan 2009 05:26:04 EST news151046764 New research led by Chu Chen, PhD, Associate Professor of Neuroscience at LSU Health Sciences Center New Orleans, provides evidence that one of the only naturally occurring fatty acids in the brain that has the ability to interact with the receptors originally identified as the targets of THC (the psychoactive component of marijuana) can help to protect brain cells from neurodegenerative diseases like Alzheimer's and Parkinson's. http://www.physorg.com/news138453637.html Medicine & Health Wed, 20 Aug 2008 12:20:37 EST news138453637
