Early life stress can leave lasting impacts on the brain

Early life stress can leave lasting impacts on the brain

For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. Continue reading

New device could improve biomarker analyses

New device could improve biomarker analyses

A device proposed by researchers at Sweden’s KTH Royal Institute of Technology could offer a more reliable alternative for detecting biomarkers in patients facing such illnesses as cancer or malaria. Whether to extract circulating tumor cells from the blood of a cancer patient, or to measure the elasticity of red blood cells due to malaria infection, the physical attributes of cells are important biomarkers in medicine.

Virus kills triple negative breast cancer cells, tumor cells in mice

Virus kills triple negative breast cancer cells, tumor cells in mice

A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer Continue reading

How keeping cool could spur metabolic benefits

How keeping cool could spur metabolic benefits

A new study being presented today at ICE/ENDO 2014, the joint meeting of the International Society of Endocrinology and the Endocrine Society in Chicago, demonstrates that ambient temperatures can influence the growth or loss of brown fat in people. Cool environments stimulate growth, warm environments loss. Brown fat, also known as brown adipose tissue, is a special kind of fat that burns energy to generate heat Continue reading

Heart physicians devise new hybrid robotic and stenting procedure

Heart physicians devise new hybrid robotic and stenting procedure

Tony Parris has worked for banks and electronics companies and has even driven an 18-wheel truck 995 miles a day for more than nine years as part of his working career. The 57-year-old Anniston native finally went into business for himself when he opened his own hardware store in Alexandria in 2010. Parris says he has worked six to seven days a week and 14- to 16-hour days for 40 years Continue reading

Exploring how the nervous system develops

Exploring how the nervous system develops

The circuitry of the central nervous system is immensely complex and, as a result, sometimes confounding. When scientists conduct research to unravel the inner workings at a cellular level, they are sometimes surprised by what they find. Continue reading

False negative results found in prognostic testing for breast cancer

False negative results found in prognostic testing for breast cancer

A recent study evaluating HER2 testing in a large cohort of women with breast cancer found important limitations in the conventional way HER2 testing is performed in the US and internationally. Dartmouth-Hitchcock Norris Cotton Cancer Center physicians and researchers retested tumor samples from a large group of women and found that 22 out of 530 women had their tumor type incorrectly classified Continue reading

Family violence leaves genetic imprint on children

Family violence leaves genetic imprint on children

A new Tulane University School of Medicine study finds that the more fractured families are by domestic violence or trauma, the more likely that children will bear the scars down to their DNA. Researchers discovered that children in homes affected by domestic violence, suicide or the incarceration of a family member have significantly shorter telomeres, which is a cellular marker of aging, than those in stable households. The findings are published online in the latest issue of the journal Pediatrics Continue reading

Nanoshell shields foreign enzymes used to starve cancer cells from immune system

Nanoshell shields foreign enzymes used to starve cancer cells from immune system

Nanoengineers at the University of California, San Diego have developed a nanoshell to protect foreign enzymes used to starve cancer cells as part of chemotherapy. Their work is featured on the June 2014 cover of the journal Nano Letters . Continue reading
