The Basque Institute for Agricultural Research and Development, Neiker-Tecnalia, has developed a new method for the early detection of the diseases mildew, powdery mildew and botrytis in vines. The new methodology based on molecular biology techniques makes it possible to detect the disease before the symptoms appear on the plant. That way it is possible to carry out the rapid treatment of the plots or areas affected and prevent the disease from spreading all over vineyard, which reduces infective pressure. The R&D centre has also studied the evolution of infection by the pathogen Plasmopara viticola –the cause of mildew– on four vine varieties: Solaris, Cabernet Sauvignon, Tempranillo and Petit Courbu. Solaris turned out to have the greatest resistance to the fungus. http://phys.org/news287314353.html Biology Thu, 09 May 2013 10:32:44 EST news287314353 (Phys.org)—A new, noninvasive, and low-cost method for the early detection and monitoring of osteoarthritis (arthritis caused by wear and tear) may be on its way, thanks to research by UC Santa Barbara scientists from the Department of Chemical Engineering and the Department of Materials. http://phys.org/news278759373.html Chemistry Wed, 30 Jan 2013 09:10:34 EST news278759373 Men aged 55 to 74 years who have low baseline blood levels of prostate specific antigen (PSA) are not likely to benefit from further screening and treatment. That is the conclusion of a new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society. The aim of the study is to help physicians and patients weigh the pros and cons of prostate cancer screening and early detection. http://phys.org/news203572927.html Medicine & Health Mon, 13 Sep 2010 05:20:02 EST news203572927 While biomarkers are needed to complement ultrasound in the early detection of hepatocellular carcinoma (HCC; liver cancer), neither des-gamma-carboxy prothrombin (DCP) nor the most widely used biomarker, alpha fetoprotein (AFP), is optimal, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. http://phys.org/news186315097.html Medicine & Health Thu, 25 Feb 2010 10:11:48 EST news186315097 Talk about house calls! The Wildlife Conservation Society thanks The Brain Tumor Foundation and its "Road To Early Detection" campaign for their assistance in performing a brain scan on a gorilla at the Bronx Zoo. http://phys.org/news157293791.html Biology Thu, 26 Mar 2009 13:43:56 EST news157293791 A group of international researchers has found the first reliable evidence that early detection of subsequent breast tumours in women who have already had the disease can halve the women's chances of death from breast cancer. http://phys.org/news156540900.html Medicine & Health Tue, 17 Mar 2009 20:35:34 EST news156540900 Prostate cancer (PCa) is one of the most common male cancers in the Western world. Currently, early detection of PCa depends on an abnormal digital rectal examination and an elevated prostate-specific-antigen (PSA) level requiring a prostate biopsy, often associated with anxiety, discomfort, complications, and heavy expenses. The prostate-cancer-gene-3 (PCA3) test is a new PCa gene-based marker carried out with a urine sample. PCA3 is highly specific to PCa and has shown promising early detection results at repeat biopsy. It may allow patients to avoid unnecessary biopsies. The PCA3 gene is dominant in over 95% of malignant prostate tissue compared to benign and normal prostate tissue. http://phys.org/news143374492.html Medicine & Health Thu, 16 Oct 2008 11:14:52 EST news143374492 A team of researchers led by Fred Hutchinson Cancer Research Center reports online today in the Journal of Clinical Oncology the validation of a potential "HIV-test" equivalent for the early detection of lung cancer. The test, which relies on immune-system signals, much like an HIV test, can detect the presence of lung cancer a year prior to diagnosis, long before symptoms appear. http://phys.org/news140762643.html Medicine & Health Tue, 16 Sep 2008 05:44:03 EST news140762643
