(Medical Xpress)—A new genomic test for prostate cancer can help predict whether men are more likely to harbor an aggressive form of the disease, according to a new UC San Francisco study. The test, which improves risk assessment when patients are first diagnosed, can also aid in determining which men are suitable for active surveillance – a way of managing the disease without direct treatment. http://medicalxpress.com/news/2013-05-prostate-cancer.html Cancer Wed, 08 May 2013 09:22:00 EST news287223712 A new genetic test to gauge the aggressiveness of prostate cancer may help tens of thousands of men each year decide whether they need to treat their cancer right away or can safely monitor it. http://medicalxpress.com/news/2013-05-gene-prostate-cancer-treatment.html Genetics Wed, 08 May 2013 04:44:19 EST news287207046 A test for hormone-disrupting pollutants, originally developed at the University of California, Davis, has been approved as an international standard by the Organization of Economic Cooperation and Development as well as by the U.S. government. http://medicalxpress.com/news/2013-01-hormone-disrupting-chemicals-global.html Other Tue, 29 Jan 2013 13:49:54 EST news278689787 Scientists have developed a quick, easy and cheap vision test to find out which part – and how much – of the brain of a stroke victim has been damaged, potentially enabling them to save more lives. http://medicalxpress.com/news/2013-01-faster-victims.html Neuroscience Fri, 04 Jan 2013 07:32:02 EST news276506990 (Medical Xpress)—Neuroscience researchers at Trinity College Dublin have opened a new avenue for research on how the brain enables us to make decisions about our environment. By observing the gradual formation of a decision in brain activity before the particular decision was actually reported, the findings also have the potential to contribute to improved understanding and diagnosis of numerous brain disorders that are associated with impaired perceptual decision making. The discovery was recently published in Nature Neuroscience. http://medicalxpress.com/news/2012-12-brain-decisions.html Neuroscience Tue, 04 Dec 2012 06:21:56 EST news273824505 Combining two approaches - one that digitally scans images of tumour samples and another that analyses genetic information - gives a more accurate prediction of how breast cancer will behave.

But just one bite from the wrong tick can rob an animal of that pastime. The bacteria Borrelia burgdorferi catch rides with certain species of ticks and can cause Lyme disease in animals the ticks bite. Catching the disease early is paramount because it becomes progressively harder to fight as the bacteria conduct guerilla warfare from hiding places in the joints, nervous tissues and organs of their hosts. http://medicalxpress.com/news/2011-06-lyme-disease-treatment-horses-dogs.html Diseases, Conditions, Syndromes Fri, 17 Jun 2011 04:43:46 EST news227504583 (Medical Xpress) -- Backed by the medical research group Human Metabolome Technologies (HMT), researchers at Keio University have developed a test which measures the concentration of phosphoric acid in the blood as an indicator of depression. http://medicalxpress.com/news/2011-05-blood-instantly-depression.html Psychology & Psychiatry Tue, 31 May 2011 11:50:01 EST news226058558 Women with ovarian cancer could be helped by a new test that identifies the specific type of tumour they have, a conference will hear this week. http://medicalxpress.com/news/2011-05-treatment-ovarian-cancer-patients.html Cancer Tue, 31 May 2011 10:20:29 EST news226056014 Five million people worldwide suffer from the chronic rheumatic disease SLE, systemic lupus erythematosus.
