New Breast Cancer Treatments Help Sufferers Gain Ground [Scientific American Magazine]
Dimanche 18 Mai 2008 - 22:00 - 6 mois, 2 semaines depuis - Presse spécialisée - Scientific American
Breast cancer is the most commonly diagnosed malignancy among women and, after lung cancer, the second leading cause of cancer-related deaths in North America. Yet unlike the survival rate for individuals diagnosed with lung cancer, the rate for women diagnosed with breast cancer has been rising dramatically over the past decade--to the point where breast cancer could soon lose its ranking as the second-greatest cancer killer. Nothing would delight clinicians like us more.This improvement in overall outlook for women diagnosed with breast cancer is attributable in part to earlier detection, which results from greater awareness of, and access to, regular breast screening. But breast cancer patients are also benefiting from accelerated research that has led to a much better understanding of the disease and a wider variety of treatment choices that doctors can mix and match to tailor therapy for a particular patient. In just the past decade, it has even become possible to target drugs to specific molecules within tumors that help to drive the disease. [More]

This Is Your Mom on Drugs: Aging Doesn't Stop Drug Use [Scientific American Magazine]
Vendredi 16 Mai 2008 - 06:18 - 6 mois, 2 semaines depuis - Presse spécialisée - Scientific American
It’s the kind of tongue-in-cheek concept that might have percolated out of the subversive imagination of R. Crumb, underground cartoon chronicler of the 1960s. Grandma and Grandpa are passing the time in their rockers--and passing a joint back and forth as they recall their youthful marijuana-smoking days in Haight-Ashbury. In fact, according to three investigators at the National Institute on Drug Abuse, the image is no joke.Writing in the journal Neuropsychopharmacology, Gayathri J. Dowling, Susan R. B. Weiss and Timothy P. Condon warn that many aging baby boomers, long accustomed to using illicit drugs for recreation and medicinals of all kinds for treating whatever ails them, will carry their love affair with drugs into old age.
