Study shows that geranylgeraniol suppresses viability of human DU145 prostate carcinoma cells

Researchers at Texas Woman's University have shown that a diterpene geranylgeraniol found in linseed oil, Cedrela toona wood oil, sucupira branca fruit oil and more recently, annatto seed oil, suppressed the viability of human DU145 prostate carcinoma cells via cell cycle arrest at the G1 phase and the initiation of apoptosis.

New studies reveal links between social status, specific brain structures and activity

New studies released today reveal links between social status and specific brain structures and activity, particularly in the context of social stress. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

Leading pediatric health system to examine causes of divergence and variability

The Department of Defense has awarded Nemours a $3.9 million grant to evaluate how physicians use best practice guidelines and to consider strategies to maintain clinical skills and consistency of care. The study, which will examine care provided throughout Nemours' pediatric health system, could help the military reintegrate physicians after deployment and better understand how their time away from routine practice affects their clinical knowledge and skill.

Study identifies patterns of brain activity associated with eating disorders

A growing body of evidence shows the impact of diet on brain function, and identifies patterns of brain activity associated with eating disorders such as binge eating and purging. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

African American men have higher risk of developing prostate cancer than European American men

African American men have a 60 percent higher risk of developing prostate cancer than European American men, and a 2.4 times higher risk of dying from the disease. Some of the reasons can be attributed to differences in screening practices and treatment, but further research is needed to determine more explicit explanations.

Single dose of intranasal insulin can help improve cognitive function in diabetes patients

In recent years, the link between type 2 diabetes and dementia has become widely recognized. Older individuals with diabetes develop Alzheimer's disease at an earlier age, and are more likely to develop vascular dementia than people who do not have diabetes.

Groundbreaking study reveals novel approach to treat, eliminate MRSA infection

Recent work from University Distinguished Professor of Biology Kim Lewis promises to overcome one of the leading public health threats of our time. In a groundbreaking study published Wednesday in the journal Nature, Lewis' team presents a novel approach to treat and eliminate methicillin resistant staphylococcus aureus, or MRSA, a potent bacterium whose resistance to antibiotics has kept it one step ahead of researchers.

Moderately preterm births add to asthma burden

Research from Finland shows that children born late preterm or early term are at significantly increased risk for asthma compared with those born at term, and these births account for the majority of excess asthma burden due to prematurity.

'Quitting cold turkey' can lead to mental decline, shows study

Can quitting drugs without treatment trigger a decline in mental health? That appears to be the case in an animal model of morphine addiction. Georgetown University Medical Center researchers say their observations suggest that managing morphine withdrawal could promote a healthier mental state in people.
