Patients with schizophrenia demonstrated improvement on a scale used to measure symptom severity after taking a drug being tested in a clinical trial, according to an article published online in the New England Journal of Medicine and co-authored by John H. Krystal, MD, Robert L. McNeil, Jr. Professor of Translational Research and Chair of the Yale Department of Psychiatry at Yale School of Medicine
Deadlier Colon Cancer Develops Differently in Women and Men
WHRY-affiliated researchers have found that colon cancer tumor cells produce energy for growth differently in women and men, and that this difference is associated with a more aggressive form of tumor growth with a higher incidence in women.
