Friends, Foes, and Everything In Between - Why Bacteria Get a Bad Rap
Friday, March 31, 2017: Humans have a fraught relationship with bacteria.

New insights into predicting the most aggressive forms of prostate cancer
Tuesday, March 14, 2017: Most prostate cancer (PCa) is diagnosed through a blood test, serum PSA testing. The well appreciated down-side of PSA testing is the diagnosis of a considerable proportion of indolent cancers that are highly unlikely to progress to clinically significant, lethal disease. Our limited ability to accurately identify men destined to suffer and die from the disease from the majority of indolent cases is a major concern and contributes to the dilemma regarding PCa screening and its genetic testing. - This paper is dedicated to the memory of our long time colleague and dear friend, Dr. Hilmi Ozcelik.
