StantonRichard Stanton has been named associate vice chancellor and associate dean for administration and finance at the School of Medicine. Stanton’s appointment, effective July 1, 2008, was announced by Larry J. Shapiro, M.D., executive vice chancellor for medical affairs and dean of the School of Medicine.

When patches of red, flaky and itchy skin on newborn mice led rapidly to their deaths, researchers at the School of Medicine looked for the reason why. What they found was a molecular alarm system that serves as a sentinel to monitor the integrity of skin — the body’s essential protective barrier. The fatal effects of raising this alarm in the lab mice suggests generally that certain kinds of impairments to the skin’s structure can potentially trigger harmful effects in other areas of the body, according to the researchers.

StamilioDavid M. Stamilio, M.D., has been named director of the Division of Maternal-Fetal Medicine at the School of Medicine, effective July 1. Stamilio is replacing Yoel Sadovsky, M.D., who became director of the Magee-Womens Research Institute at the University of Pittsburgh. Stamilio’s appointment was announced by George Macones, M.D., chair of the Department of Obstetrics and Gynecology.

A unique genetic signature can alert physicians to high-risk breast tumors that are masquerading as low-risk tumors, according to research at the School of Medicine and collaborating institutions. Although these tumors are apparently estrogen-receptor positive — meaning they should depend on estrogen to grow — they don’t respond well to anti-estrogen therapy.

Researchers at the School of Medicine have defined a new type of immune response that is activated in patients with severe asthma and COPD (chronic obstructive pulmonary disease). Their discovery could dramatically improve diagnosis and treatment of patients with chronic inflammatory lung disease.

Changing the sugars attached to a hormone produced in the pituitary gland increased fertility levels in mice nearly 50 percent, a research group at the School of Medicine has found. The change appears to alter a reproductive “thermostat,” unveiling part of an intricate regulatory system that may one day be used to enhance human fertility.

Maintaining bone density could be a key to decreasing the spread of cancer in women with locally advanced breast cancer, according to research at the School of Medicine. Bones are common sites for the spread, or metastasis, of breast cancer. Scientists here found that women treated for stage II/III breast cancer who also received a bone strengthening drug were less likely to have breast tumor cells growing in their bones after three months.

Mothers, here’s another reason to encourage your daughters to be physically active: Girls and young women who exercise regularly between the ages of 12 and 35 have a substantially lower risk of breast cancer before menopause compared to those who are less active, new research shows.

Scientists at the School of Medicine working with diabetic mice have examined in unprecedented detail the immune cells long thought to be responsible for type 1 diabetes. Researchers were able to examine the immune cells from isolated insulin-making structures in the pancreas known as the islets of Langerhans.

An international consortium of scientists, led by the School of Medicine, has decoded the genome of the platypus, showing that the animal’s peculiar mix of features is reflected in its DNA. An analysis of the genome, published today in the journal Nature, can help scientists piece together a more complete picture of the evolution of all mammals, including humans.
