Using powerful X-rays, University of British Columbia researchers have reconstructed a crime scene too small for any microscope to observe – and caught the culprit of arrhythmia in action. http://medicalxpress.com/news/2013-02-arrhythmia-culprit-caught-action.html Medical research Sun, 17 Feb 2013 13:30:02 EST news280329612 Proposed cancer therapeutic drugs based on blocking the catalytic activities of matrix metalloproteinases (MMPs), which profoundly remodel the environment surrounding a breast cell, have performed poorly in clinical trials. In mouse studies of MMP14, an enzyme that is often highly expressed in breast cancer, Berkeley Lab researchers have found a possible clue as to why. If confirmed for other MMPs, the finding could point the way to new strategies for future MMP-based cancer therapies. http://medicalxpress.com/news/2013-02-clue-clinical-trial-failures-mmp.html Cancer Tue, 12 Feb 2013 08:09:36 EST news279878956 (HealthDay)—Diet can have a notable impact on reproductive health, a group of new studies suggests. http://medicalxpress.com/news/2012-10-dairy-carbs-men-sperm.html Health Fri, 26 Oct 2012 11:10:01 EST news270466313 A common bacteria ever-present on the human skin and previously considered harmless, may, in fact, be the culprit behind chronic sinusitis, a painful, recurring swelling of the sinuses that strikes more than one in ten Americans each year, according to a study by scientists at the University of California, San Francisco. http://medicalxpress.com/news/2012-09-links-sinusitis-microbial-diversity-approach.html Diseases, Conditions, Syndromes Wed, 12 Sep 2012 14:00:01 EST news266675084 (Medical Xpress)—Eyewitness identification evidence is often persuasive in the courtroom and yet current eyewitness identification tests often fail to pick the culprit. Even worse, these tests sometimes result in wrongfully accusing innocent suspects.

The culprit was Pythium insidiosum, a fungus-like microbe which rarely causes disease in humans and then primarily in Thailand. The case “clearly highlights the need for clinicians to have the best support possible from the clinical microbiology lab,” says Don Murphey of Cook Children’s Medical Center, who served as attending physician during the case.
