ANN ARBOR, Mich.—Preschoolersers are aware and understand threats when they see their mother harmed by violent conflicts at home, a new University of Michigan study finds.

The study explored what factors influence children’s comprehension and response when violence occurs.

Researchers evaluated intimate partner violence—conflicts that can be physical or sexual—in the past year for 116 mother-child groups with known violence in the homes. The children were 4 to 6 years old.

Few studies have looked at children’s observations of violence as young as age 5, and the new U-M findings are one of the first to assess outcomes for kids as young as age 4, said Laura Miller, a psychology graduate student and study’s lead author. (more…)

COLUMBIA, Mo. – Individuals who practice religion and spirituality report better physical and mental health than those who do not. To better understand this relationship and how spirituality/religion can be used for coping with significant health issues, University of Missouri researchers are examining what aspects of religion are most beneficial and for what populations. Now, MU health psychology researchers have found that religious and spiritual support improves health outcomes for both men and women who face chronic health conditions. (more…)

*Bacterial cells have gene mutations that allow them to ‘stick’ to the devices*

New research suggests that some patients develop a potentially deadly blood infection from their implanted cardiac devices because bacterial cells in their bodies have gene mutations that allow them to stick to the devices.

Geoscientists were the major contributors to the finding.

Proceedings of the National Academy of Sciences published the study results online this week. (more…)

Breast Tenderness Following Combo Hormone Therapy Linked To Increased Breast Density

*Study examines biology underlying link between tenderness, cancer risk*

Post-menopausal women who experience breast tenderness after starting combination hormone therapy have a higher risk of breast cancer than women who don’t, a study by researchers with UCLA’s Jonsson Comprehensive Cancer Center has shown. One reason for this, they now say, may be that these women’s breasts are becoming more dense.

Such new-onset tenderness was found to be more pronounced after the start of combination estrogen-and-progestin therapy than with estrogen therapy alone. The link between new-onset tenderness and changes in breast density also was more pronounced in women on combination therapy, said the study’s first author, Dr. Carolyn Crandall, a UCLA professor of general internal medicine and a scientist with the Jonsson Cancer Center.

COLUMBUS, Ohio – For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle.

The technique uses electricity to “shoot” bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second.

L. James Lee and his colleagues at Ohio State University describe the technique in the online edition of the journal Nature Nanotechnology, where they report successfully inserting specific doses of an anti-cancer gene into individual leukemia cells to kill them. (more…)

New Research Links Common RNA Modification to Obesity

An international research team has discovered that a pervasive human RNA modification provides the physiological underpinning of the genetic regulatory process that contributes to obesity and type II diabetes.

European researchers showed in 2007 that the FTO gene was the major gene associated with obesity and type II diabetes, but the details of its physiological and cellular functioning remained unknown. (more…)

New Method helps Researchers Zero in on Drugs that can kill Brain Cancer Stem Cells

Researchers with UCLA’s Jonsson Comprehensive Cancer Center have developed a new screening approach to identify chemical compounds that can target and kill the stem cells responsible for creating deadly brain tumors.

Glioblastoma is one of the deadliest malignancies, typically killing patients within 12 to 18 months. These brain cancers consist of two kinds of cells: a larger, heterogeneous population of tumor cells and a smaller sub-population of stem cells, which are treatment-resistant. (more…)

“Drunkorexia:” A Recipe for Disaster

*MU study finds disordered eating combined with heavy drinking is common among college students*

COLUMBIA, Mo. – It is well known that eating disorders are common among teens and college students. Heavy alcohol consumption is another well-known unhealthy habit of this age group. A new study from the University of Missouri shows that when college students combine these two unhealthy habits, their long-term health may be affected. “Drunkorexia” is a new term coined by the media to describe the combination of disordered eating and heavy alcohol consumption.

Victoria Osborne, assistant professor of social work and public health, examined the relationship between alcohol misuse and disordered eating, including calorie restriction and purging. Researchers found that 16 percent of those surveyed reported restricting calories to “save them” for drinking. Of the respondents, about three times as many women reported engaging in the behavior than men. Motivations for “drunkorexia” include preventing weight gain, getting intoxicated faster and saving money that would be spent on food to buy alcohol. (more…)
