(PhysOrg.com) -- Researchers at Uppsala University and University Children`s Hospital in Uppsala have devised powerful new tools for typing cells from children with acute lymphatic leukemia and for prediction of how children with leukemia will respond to chemotherapy. The study was recently published in electronic form by the prestigious hematological journal Blood. http://www.physorg.com/news178550370.html Medicine & Health Fri, 27 Nov 2009 13:21:30 EST news178550370 Tiny particles that can carry drugs and target cancer cells may offer treatment hope for those suffering with pancreatic cancer. New research to be presented in November at the American Association of Pharmaceutical Scientists (AAPS) Annual Meeting in Los Angeles reveals that tumor-penetrating microparticles (TPM) have been specifically designed to break through hard-to-infiltrate barriers and deliver drugs more effectively and efficiently than the standard form of chemotherapy such as those injected through a vein. http://www.physorg.com/news176392083.html Medicine & Health Mon, 02 Nov 2009 14:20:01 EST news176392083 Colonoscopy represents one of the great weapons against cancer. In one step, a physician can find precancerous lesions in the colon and then cut them out, an on-the-spot intervention that prevents cancer from developing. Now, researchers at the Winthrop Rockefeller Cancer Institute and the University of Arkansas for Medical Sciences have developed another fiber optic technique that can detect lymph node metastases and destroy them on the spot, an action that could prevent the further spread of breast cancer, melanoma, or gastrointestinal cancer, all of which spread through the lymphatic system. http://www.physorg.com/news176116481.html Nanotechnology Fri, 30 Oct 2009 10:15:06 EST news176116481 It is possible to simultaneously survey a number of neglected tropical diseases (NTDs) in the challenging environment of Southern Sudan, according to a new study published October 27 in the open-access journal PLoS Neglected Tropical Diseases. The research, coordinated by Malaria Consortium Africa on behalf of the government of Southern Sudan, rapidly identified areas requiring mass treatment for schistosomiasis and intestinal worm infections, and showed that two diseases, lymphatic filariasis and loiasis, were not endemic in Northern Bahr-el-Ghazal State, an area the size of Belgium. http://www.physorg.com/news175842633.html Medicine & Health Tue, 27 Oct 2009 06:11:05 EST news175842633 As breast cancer awareness month is observed during October, the American Physical Therapy Association (APTA) is hoping to shine a spotlight on lymphedema, a chronic, debilitating and often irreversible side effect of cancer treatment. http://www.physorg.com/news174846489.html Medicine & Health Thu, 15 Oct 2009 17:28:54 EST news174846489 Researchers at the University of Toronto, St. Michael's Hospital and Sunnybrook Health Sciences Centre have discovered a previously unidentified form of circulation within the human eye which may provide important new insights into glaucoma, a leading cause of blindness. http://www.physorg.com/news173966488.html Medicine & Health Mon, 05 Oct 2009 13:30:02 EST news173966488 Infecting mosquitoes with a bacterial parasite could help prevent the spread of lymphatic filariasis, one of the major neglected tropical diseases of the developing world, according to research published today in the journal Science. http://www.physorg.com/news173627112.html Biology Thu, 01 Oct 2009 15:30:01 EST news173627112 (PhysOrg.com) -- Biomedical researchers at the University of Arkansas in Fayetteville and the University of Arkansas for Medical Sciences (UAMS) in Little Rock have developed a special contrast-imaging agent made of gold-coated carbon nanotubes that is capable of molecular mapping of lymphatic endothelial cells and detecting cancer metastasis in sentinel lymph nodes. The findings from this study, which was led by Jin-Woo Kim, Ph.D., M.S., University of Arkansas, and Vladimir P. Zharov, Ph.D., D.Sc., M.S., UAMS, were published in the journal Nature Nanotechnology. http://www.physorg.com/news172951791.html Nanotechnology Thu, 24 Sep 2009 17:10:01 EST news172951791 Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth. http://www.physorg.com/news169124797.html Medicine & Health Mon, 10 Aug 2009 12:07:08 EST news169124797 Our bodies' tissues need continuous irrigation and drainage. Blood vessels feeding the tissues bring in the fluids, and drainage occurs via the lymphatic system. While much is known about how blood vessels are built, the same was not true for lymph vessels. Now though, Norrmén et al. have identified two of the lead engineers that direct drainage construction in the mouse embryo. http://www.physorg.com/news160028799.html Medicine & Health Mon, 27 Apr 2009 05:26:59 EST news160028799 The side effects of an experimental "gene-silencing" treatment that is currently being investigated for a variety of diseases are even more wide-ranging than previously discovered, according to a study by a University of Kentucky researcher. http://www.physorg.com/news158257334.html Medicine & Health Mon, 06 Apr 2009 17:22:36 EST news158257334 Scientists at St. Jude Children's Research Hospital have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade it. http://www.physorg.com/news147357294.html Medicine & Health Mon, 01 Dec 2008 12:34:54 EST news147357294 (PhysOrg.com) -- Researchers have identified a gene critical for the development of the lymphatic system in a discovery that will have implications for treatment of cancer and lymphatic disorders and other diseases. http://www.physorg.com/news143709300.html Medicine & Health Mon, 20 Oct 2008 08:15:00 EST news143709300 A study published today concludes that in the ten years since its initiation, the international effort to eliminate lymphatic filariasis (LF) has made a large impact towards ridding the world of one of its most debilitating diseases. The analysis found that the LF elimination programme has prevented 6.6 million children from acquiring LF and stopped another 9.5 million people already infected with the disease from progressing to more debilitating stages. These efforts are the result of the most rapid scale-up of a drug administration programme in public health history, delivering what the study calls a "best buy in public health". http://www.physorg.com/news142656435.html Medicine & Health Wed, 08 Oct 2008 03:47:15 EST news142656435
