The study also shows an increase in certain strains of typhoid fever that are resistant to the most commonly used medications for treatment. http://www.physorg.com/news170438721.html Medicine & Health Tue, 25 Aug 2009 17:50:01 EST news170438721 Colorectal cancer (CRC) is the second leading cause of cancer-related death in the Western world. Fortunately physicians today have an abundance of drug therapies available to improve survival length for more advanced cancer patients. Now the discovery of genetic biomarkers relevant to CRC means that targeted personalised medication is increasingly common. http://www.physorg.com/news170073793.html Medicine & Health Fri, 21 Aug 2009 12:10:01 EST news170073793 Tracking down new active agents for cancer or malaria treatment could soon become easier - thanks to a computer program with which researchers from the Max Planck Institute of Molecular Physiology in Dortmund aim to facilitate the search for suitable pharmaceutical substances. http://www.physorg.com/news168857709.html Chemistry Fri, 07 Aug 2009 09:55:48 EST news168857709 (PhysOrg.com) -- A recent study on human genetics on various populations across the world conducted by researchers from the Institut Pasteur and the CNRS (France) has shown how pathogens can shape the patterns of genetic diversity of our immune system over time. Results show that bacteria, fungi and parasites, unlike viruses, appear to have allowed the introduction of mutations in the genes of some proteins of the innate immunity system, thus enabling greater genetic variability. In some cases, these mutations may even constitute an advantage, giving the human host improved resistance to infectious diseases such as leprosy or tuberculosis. http://www.physorg.com/news168014649.html Medicine & Health Tue, 28 Jul 2009 15:45:45 EST news168014649 Older patients with diabetes who take antipsychotic medications appear to have an increased risk of hospitalization for hyperglycemia (elevated blood glucose level), especially soon after beginning treatment, according to a report in the July 27 issue of Archives of Internal Medicine. http://www.physorg.com/news167935517.html Medicine & Health Mon, 27 Jul 2009 18:20:01 EST news167935517 Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing. The researchers describe gel composed of silver nanoparticles - each 1/50,000th the width of a human hair - that appears more effective than these traditional gels. Their study is scheduled for the Aug. 3 issue of ACS' Molecular Pharmaceutics. http://www.physorg.com/news167477979.html Nanotechnology Wed, 22 Jul 2009 10:40:25 EST news167477979 (PhysOrg.com) -- A Vanderbilt chemist and a biomedical engineer have teamed up to develop a respiratory virus detector that is sensitive enough to detect an infection at an early stage, takes only a few minutes to return a result and is simple enough to be performed in a pediatrician's office. http://www.physorg.com/news165489614.html Chemistry Mon, 29 Jun 2009 10:21:01 EST news165489614 Though the growing shift toward oral chemotherapy agents offers cancer patients greater freedom and independence during their treatment, physicians say use of the new medications also poses more chances for patients to skip doses, miss prescription refills, and take their drugs in a dangerous way. An increasing number of cancer patients who receive chemotherapy now do so at home, with the click of a pill bottle each day rather than the drip of an IV medicine that must be delivered in a doctor's office or hospital. http://www.physorg.com/news162740105.html Medicine & Health Thu, 28 May 2009 14:35:40 EST news162740105 A laboratory study by researchers at Albert Einstein College of Medicine of Yeshiva University suggests that an anti-cancer compound studied for treating blood cancers may also help in treating cancers of the head and neck. The work is reported in the April 28th online edition of the Journal of Pathology. http://www.physorg.com/news160153426.html Medicine & Health Tue, 28 Apr 2009 16:05:55 EST news160153426 (PhysOrg.com) -- Ten years ago, William Fenical of the Scripps Institution of Oceanography isolated from an ocean-living fungus a compound that has since shown the ability to kill cancer cells in the lab. Now, for the first time, MIT chemists have synthesized the compound, an advance that could open the door to new drug treatments for cancer. http://www.physorg.com/news159974241.html Chemistry Sun, 26 Apr 2009 14:18:00 EST news159974241 Researchers from the Children's Cancer Hospital at The University of Texas M.

A review of 33 HBV outbreaks, published in the open access journal BMC Medicine, has shown that the most frequent HBV transmission routes are administration of drugs using multi-vial compounds and capillary blood sampling (e.g. for glucose monitoring) using non-disposable devices. http://www.physorg.com/news158474856.html Medicine & Health Thu, 09 Apr 2009 05:48:15 EST news158474856 (PhysOrg.com) -- Oxford researchers have reported results from a study of death and cancer rates in military veterans who took part in the Ministry of Defence`s Human Volunteer Programme at Porton Down between 1941 and 1989. http://www.physorg.com/news157220624.html Medicine & Health Wed, 25 Mar 2009 17:25:33 EST news157220624 Serious flaws in a recent study, which concluded that high doses of vitamin C reduce the effectiveness of chemotherapeutic drugs in the treatment of cancer, are revealed in the current issue of Alternative and Complementary Therapies, a journal published by Mary Ann Liebert, Inc. http://www.physorg.com/news155564558.html Medicine & Health Fri, 06 Mar 2009 12:23:10 EST news155564558 A new, recently licensed medical device developed by University at Buffalo researchers would introduce into intensive care settings the powerful and effective method of anesthetizing patients that works so well in the operating room. http://www.physorg.com/news154791466.html Medicine & Health Wed, 25 Feb 2009 13:38:24 EST news154791466 One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor. Now, Neil Forbes, Ph.D., and his colleagues at the University of Massachusetts have built a microfluidic device that can mimic these chemical and physical barriers, providing researchers with a new screening tool that may help with the design of more effective anticancer drugs. http://www.physorg.com/news154627972.html Chemistry Mon, 23 Feb 2009 16:13:39 EST news154627972 (PhysOrg.com) -- In recent years, scientists have isolated two potent natural antibiotics - platensimycin and platencin - that are highly effective against bacterial infection, including those caused by the most dreaded drug-resistant microbes. http://www.physorg.com/news154193863.html Chemistry Wed, 18 Feb 2009 15:38:29 EST news154193863 The structure, described February 8 in an advance online publication of the journal Nature, provides fresh insights into the elegant dance that viral proteins perform to create the infectious structure that causes all manner of misery and disease, say researchers. While the virus they studied, HK97, only infects bacteria, well-known viruses such as herpes and HIV are also known to assemble an "intermediary" structure before morphing into its final assault-proof, infectious form. http://www.physorg.com/news153323957.html Biology Sun, 08 Feb 2009 14:00:14 EST news153323957 Scientists including one from The University of Texas Health Science Center at Houston successfully predicted the outcome of a nano drug on breast tumors in a pre-clinical study.
