- Single antibody shrinks variety of human tumors transplanted into mice, study shows – Human tumors transplanted into laboratory mice disappeared or shrank when scientists treated the animals with a single antibody, according to a new study from the Stanford University School of Medicine. The antibody works by masking a protein flag on cancer cells that protects them from macrophages and other cells in the immune system. The scientists achieved the findings with human breast, ovarian, colon, bladder, brain, liver and prostate cancer samples.

cardiology fellow at BWH and researcher in the TIMI Study Group, who is the lead author on this study. "Interestingly, we did find a dramatic difference in practice patterns of physicians in North America compared to those in the rest of the world," Kohli said. "North American physicians prescribed a high dose of aspirin for two-thirds of all their patients, while the exact reverse was true of the rest of the world. International physicians prescribed a low dose of aspirin to more than two-thirds of their patients." Dr. Stephen D. Wiviott, a cardiologist at BWH and researcher in the TIMI Study Group, is the senior author on the study.
