The natural compound xanthohumol blocks the effects of the male hormone testosterone, therefore aiding in the prevention of prostate cancer. http://www.physorg.com/news179522288.html Medicine & Health Tue, 08 Dec 2009 19:18:47 EST news179522288 The November issue of European Urology, the official journal of the European Association of Urology, features an article focussing on prostate specific antigen (PSA) velocity and early cancer detection. It has been suggested that changes in PSA over time aid prostate cancer detection. http://www.physorg.com/news176644002.html Medicine & Health Thu, 05 Nov 2009 11:47:29 EST news176644002 Fox Chase Cancer Center researchers report that radiation therapy alone can reduce prostate specific antigen (PSA) levels below detectable amounts in prostate cancer patients. Patients who have an undetectable level of PSA after therapy have less chance of biochemical failure than other patients and a good chance of being cured. The data was presented today at the annual meeting of the American Society for Radiation Oncology. http://www.physorg.com/news176402411.html Medicine & Health Mon, 02 Nov 2009 19:00:02 EST news176402411 Clinical researchers at Princess Margaret Hospital (PMH) can now answer the question that baffles many clinicians - why do some men with elevated prostate specific antigen (PSA) levels who are carefully monitored and undergo repeated negative biopsies still develop aggressive prostate cancer? http://www.physorg.com/news174219183.html Medicine & Health Thu, 08 Oct 2009 11:30:01 EST news174219183 Men with early stages of prostate cancer who delay radical treatment in favor of an approach of "expectant management" do not have high levels of anxiety and distress. That is the conclusion of a new study published in the September 1, 2009 issue of Cancer, a peer-reviewed journal of the American Cancer Society. The study's results suggest that living with untreated cancer is not upsetting for many patients with early prostate cancer. http://www.physorg.com/news167904692.html Medicine & Health Mon, 27 Jul 2009 09:30:05 EST news167904692 Two Mayo Clinic patients whose prostate cancer had been considered inoperable are now cancer free thanks in part to an experimental drug therapy that was used in combination with standardized hormone treatment and radiation therapy. The men were participating in a clinical trial of an immunotherapeutic agent called MDX-010 or ipilimumab. In these two cases, physicians say the approach initiated the death of a majority of cancer cells and caused the tumors to shrink dramatically, allowing surgery. In both cases, the aggressive tumors had grown well beyond the prostate into the abdominal areas. http://www.physorg.com/news164641955.html Medicine & Health Fri, 19 Jun 2009 14:52:51 EST news164641955 Fifty-five percent of children who underwent an intensive so-called one-session treatment of three hours were freed from their phobia. The treatment is carried out on a single occasion, is quick and cost-effective, with no side effects. The treatment form is also culture-neutral and does not need to be adapted to the country or the place it is to be used. This is shown by Lena Reuterskiold at the Department of Psychology, Stockholm University in Sweden, in the dissertation she recently submitted. http://www.physorg.com/news157301130.html Medicine & Health Thu, 26 Mar 2009 15:46:01 EST news157301130 Certain men age 75 to 80 are unlikely to benefit from routine prostate specific antigen (PSA) testing, according to a Johns Hopkins study published in the April 2009 issue of The Journal of Urology. http://www.physorg.com/news154333146.html Medicine & Health Fri, 20 Feb 2009 06:19:36 EST news154333146 The immune system's battle against invading bacteria reaches its peak activity at night and is lowest during the day. http://www.physorg.com/news148486853.html Biology Sun, 14 Dec 2008 14:20:53 EST news148486853 A study conducted on hundreds of rats could help us understand how the brain identifies specific sounds in a noisy environment. The investigation, soon to be published in the journal Brain, was conducted by Alex Martin of the Université de Montréal Department of Psychology. http://www.physorg.com/news146231125.html Medicine & Health Tue, 18 Nov 2008 11:45:25 EST news146231125 A doctoral thesis carried out at the University of Granada, Spain, has proved that patients with serious anxiety disorders (panic disorder with and without agoraphobia, social anxiety disorder or generalized anxiety disorder) think they suffer more physiological (palpitations, sweating, irregular breathing, shaking of the hands and muscular tension...) than they really have. In other words, although many patients with anxiety disorders have orally reported very intense physiological symptoms in surveys and questionaires, they are hyporeactive when real measures of such symptoms are taken through physiological tests. http://www.physorg.com/news145791840.html Medicine & Health Thu, 13 Nov 2008 09:44:00 EST news145791840 Patients 80 years and older who are in overall good health are perfectly able to withstand open-heart surgery, according to the latest study of Dr. Kevin Lachapelle of the McGill University Health Centre (MUHC). His findings were presented this morning in Toronto during the 2008 Canadian Cardiovascular Congress. http://www.physorg.com/news144413812.html Medicine & Health Tue, 28 Oct 2008 11:56:52 EST news144413812 (PhysOrg.com) -- Research published by scientists from the University of Reading may offer an insight into ways of making safer and more specific gene therapy vectors. The research, published in the journal Nature Structural and Molecular Biology, describes the structure of the viral fusion protein gp64, which is involved in the mechanism which viruses use to invade host cells. In the past, Bacloviruses have been suggested as possible gene therapy vectors due to the way in which they enter host cells, but there has been little evidence which explain these properties up to now. http://www.physorg.com/news142610761.html Biology Tue, 07 Oct 2008 15:06:01 EST news142610761 In a landmark study, Medical College of Wisconsin researchers in Milwaukee report that drugs used to inhibit a specific fatty acid in rat brains with glioblastoma-like tumors not only reduced new blood vessel growth and tumor size dramatically, but also prolonged survival.
