Scientists at the Children’s Hospital Oakland Research Institute (CHORI) Nutrition & Metabolism Center recently announced that they have developed a low-calorie, high-fiber, fruit-based vitamin and mineral nutrition bar called the CHORI-bar, which improves biomarkers linked to risk of cardiovascular disease, cognitive decline, and associated decline in antioxidant defenses.

Mitochondria are specialized subunits inside a cell that produce the cell’s energy and regulate its metabolism. Research suggests that mitochondria may play a central role in neuronal cell survival because they regulate both energy metabolism and cell death pathways. Using genetic mouse models of Alzheimer’s disease, researchers from Mayo Clinic have found that mitochondria in the brain are dysfunctional early in the disease. The findings were recently published in the open access journal PLoS ONE.

We are all familiar with the negative consequences of getting too little sleep, but they may be more serious than just feeling a bit groggy. A new study published in the journal Science Translational Medicine has shown that sleep restriction, along with a disruption of one’s internal body clock, can raise the risk of obesity and type 2 diabetes [1]. This could explain the increased rates of these conditions in shift workers and others who work at night.

A heart attack, or myocardial infarction (MI), occurs when a portion of the heart muscle becomes oxygen-starved due to clogged blood vessels. This can damage or kill the affected portion of muscle. Depending upon the amount of muscle involved, heart attacks range from mild to life-threatening. The best predictor of whether a heart attack sufferer will survive an acute MI is their ability to identify that a heart attack is taking place and get medical help.

According to an article in the Morbidity and Mortality Weekly Report, a publication of the U.S. Centers for Disease Control and Prevention (CDC), the prevalence of autism spectrum disorder (ASD) is higher than ever [1]. The CDC periodically surveys the prevalence of ASD, looking during each surveillance period at the percentage of 8-year-old children who have current ASD diagnoses. In 2000, a survey of children born in 1992 revealed that one in 150 had ASD. These numbers have been steadily climbing, such that the most recent survey — completed in 2008 and surveying children born in 2000 — indicates that one in 88 children has ASD. The numbers are even more disturbing for male children, who have an ASD prevalence of one in 54.
