http://medicalxpress.com/ en-us Medical Xpress provides the latest news from Lawson Health Research Institute For women diagnosed with a form of breast cancer known as estrogen receptor positive (ER+) breast cancer, tamoxifen is an essential drug used in the treatment and prevention of recurring breast cancer. Currently, tamoxifen is used in a one-size-fits-all approach where the same dose is prescribed for every patient. New research at Lawson Health Research Institute has found that in addition to patient-specific genetic factors, lack of exposure to vitamin D during the long winter months affects the body's ability to metabolize the drug. http://medicalxpress.com/news/2013-04-cold-winters-breast-cancer-treatment.html Cancer Thu, 18 Apr 2013 14:30:01 EST news285512979 The impact of bipolar disorder during pregnancy has been hotly contended among the research community. Now, a new study from Lawson Health Research Institute and Western University is sorting out the debate and calling for more targeted, prospective research. http://medicalxpress.com/news/2012-08-lawson-baby-blues.html Psychology & Psychiatry Wed, 22 Aug 2012 10:28:44 EST news264850105 If detected early, most cases of breast cancer are curable. But if the tumour has metastasized – or spread to a site outside of the breast – cure rates decline. A team of researchers from Lawson Health Research Institute and Western University have received $449,733 from the Canadian Breast Cancer Foundation – Ontario Region to study a rare subpopulation of tumour cells called cancer stem cells (CSCs) in hopes of uncovering the mystery behind metastasis. http://medicalxpress.com/news/2012-08-breast-cancer-cells-discerning.html Cancer Tue, 07 Aug 2012 13:05:41 EST news263563485 A team of researchers at Lawson Health Research Institute and Western University have identified a novel way that a common virus, called adenovirus, causes disease. In doing so, they have discovered important information on one of the body's key immune responses. Their findings, published today in Cell Host & Microbe, may have implications for infectious diseases and cancer. http://medicalxpress.com/news/2012-06-london-mechanism-involved-key-immune.html Immunology Wed, 13 Jun 2012 14:12:42 EST news258815556 Ontario doctors are legally required to report patients they consider medically unfit to drive to the Ministry of Transportation (MTO) – yet they may not be doing it.
