Findings about testosterone levels illuminate how humans evolved to form alliances

COLUMBIA, Mo. – After outgrowing teenage infatuations with the girl next door, adult males seem to be biologically designed to avoid amorous attractions to the wife next door, according to a University of Missouri study that found adult males’ testosterone levels dropped when they were interacting with the marital partner of a close friend. Understanding the biological mechanisms that keep men from constantly competing for each others’ wives may shed light on how people manage to cooperate on the levels of neighborhoods, cities and even globally.

COLUMBUS, Ohio – Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find.

Many animal studies have suggested that vitamin E could prevent cancer, but human clinical trials following up on those findings have not shown the same benefits. (more…)

Scientist works toward molecular therapies for cardiovascular diseases

Born in Leningrad (now St. Petersburg), Russia, to Jewish parents before the fall of the Soviet Union, Michael Simons, M.D., says a medical career was “sort of a default.” Anti-Semitism barred Jews from many scientific pursuits, so his parents, both doctors, encouraged his interest in medicine as the basis for a strong natural science education.

Simons’ family immigrated to Boston in 1978. Simons had begun a 6-year medical program immediately after high school in Russia, so he was admitted to Boston University School of Medicine as a third-year student, but he chose instead to start anew, as an undergraduate. “I thought, if I continue in a medical program, I’ll forever have an inadequate undergraduate education,” he says, speaking with a mild accent and an understated intensity.

Proximity to Coal-Tar-Sealed Pavement Raises Risk of Cancer, Study Finds

People living near asphalt pavement sealed with coal tar have an elevated risk of cancer, according to a study in the journal Environmental Science and Technology. Much of this calculated excess risk results from exposures in children, age six or younger, to polycyclic aromatic hydrocarbons (PAHs) from the sealant.

“The increased cancer risk associated with coal-tar-sealed asphalt (CSA) likely affects a large number of people in the U.S. Our results indicate that the presence of coal-tar-based pavement sealants is associated with significant increases in estimated excess lifetime cancer risk for nearby residents,” said E. Spencer Williams, Ph.D., principal author of the study and Baylor University assistant research scientist at the Center for Reservoir and Aquatic Systems Research in Baylor’s College of Arts & Sciences.

Peer support shows promise in epilepsy fight

Peer support groups show promise for combating the debilitating stigma that surrounds epilepsy in much of the developing world, according to a new study led by a Michigan State University medical student.

The researchers report in the journal Epilepsy and Behavior that young people with the disease felt significantly less stigmatized after meeting regularly to discuss their illness. (more…)

Political strife undermines HIV treatment

Among other tragedies in countries with HIV epidemics, political violence can have the additional long-term consequence of an increase in viral resistance to treatment and HIV treatment failure, say the authors of a new paper in AIDS Reviews. The researchers, who have studied post-strife treatment failure and resistance in Kenya, argue that officials and health care providers need to study and prepare for how violence disrupts antiretroviral treatment and complicates the epidemic.

Tenfold boost in ability to pinpoint proteins in cancer cells

Better diagnosis and treatment of cancer could hinge on the ability to better understand a single cell at its molecular level. New research offers a more comprehensive way of analyzing one cell’s unique behavior, using an array of colors to show patterns that could indicate why a cell will or won’t become cancerous.

A University of Washington team has developed a new method for color-coding cells that allows them to illuminate 100 biomarkers, a ten-time increase from the current research standard, to help analyze individual cells from cultures or tissue biopsies. The work is published this week (March 19) in Nature Communications. (more…)

Man who received nation’s first ‘breathing lung’ transplant at UCLA thankful for gift of life

Grandfather, 57, looks forward to celebrating Easter with family and friends

Fernando Padilla could barely breathe or walk more than a few steps. An incurable disease, pulmonary fibrosis, was causing his lungs to turn to hardened scar tissue, and he was permanently tethered to an oxygen tank. His only hope was a double lung transplant.
