Treating ovarian cancer with the drug bevacizumab (“Avastin”) delays the disease and may also improve survival, according to an international clinical trial co-led by Drs. Amit Oza of the University of Toronto and Princess Margaret Hospital (PMH) and Timothy Perren of St James’s Institute of Oncology, Leeds, U.K.
The findings, published on Dec. 28 in the New England Journal of Medicine, report that the drug halted the cancer’s return for two months overall. However, for women with the highest risk disease, the delay was five to six months and in this group, the findings also indicate a strong trend to improved overall survival, which is being analysed until 2013.

For decades, science has suggested that when people make decisions, they tend to ignore logic and go with the gut. But Wim De Neys, a psychological scientist at the University of Toulouse in France, has a new suggestion: Maybe thinking about logic is also intuitive. He writes about this idea in the January issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science.(more…)
*Proprotein convertases are enzymes that activate many essential proteins, but they are also implicated in many processes that cause disease. In a research review in the New England Journal of Medicine, Andrew Artenstein and Steven Opal argue that proprotein convertases are potentially rich targets for developing therapies.*
Most people have never heard of proprotein convertases, but the enzymes activate many proteins that are essential for life. Unfortunately, their fundamental role puts them in the middle of many processes that cause disease – not just cancer or athlerosclerosis, but both of those and Alzheimer’s and anthrax and the flu and an amazing variety of other maladies.
In a research review article appearing Dec. 29 in the New England Journal of Medicine, Andrew Artenstein, physician-in-chief in the Department of Medicine at Memorial Hospital, and Steven Opal, chief of infectious diseases at Memorial Hospital, argue that proprotein convertases (PCs) are potentially rich targets for developing therapies. Artenstein, who with Opal is on the faculty of the Warren Alpert School of Medicine, explained PCs to David Orenstein. (more…)
