Private sector scientists today announced the publication of a paper that describes novel findings suggesting that genomic rearrangements, not single base pair changes in DNA, provide the genetic basis for the differences between humans and non-human primates such as the chimpanzee.
The presence of tumor-infiltrating lymphocytes predicts the length of remission after chemotherapy and the overall survival of patients with ovarian cancer, according to researchers from the Abramson Cancer Center and the Center on Women's Health at the University of Pennsylvania School of Medicine. Their findings, which are presented in the January 16th issue of the New England Journal of Medicine, constitute the first proof that a spontaneous immune response against the tumor dramatically impacts the clinical course of ovarian cancer. These novel findings generate hope that immune therapies may significantly prolong the response to chemotherapy and improve the survival of patients with advanced ovarian carcinoma.
It's a cruel irony that strikes many victims of spinal cord injury: In those who suffer only partial paralysis, limbs that should remain healthy become stiff and useless because of chronic spasticity, a painful condition that causes muscles to contract involuntarily. But Florida researchers charting the development of spasticity in rats with spinal cord injuries were surprised to find the process briefly reverses itself. This discovery raises the possibility that physicians could someday find a way to spare patients its debilitating effects by intervening at a critical time.
