A study from UT Southwestern researchers found that recently introduced cholesterol guidelines would significantly reduce new cardiovascular events, when compared to treatment based on previous cholesterol guidelines. The research identified Dallas Heart Study participants in the 30 to 65 age range who would have newly qualified for statin use under the new cholesterol guidelines introduced in 2013 by the American College of Cardiology (ACC) and the American Heart Association (AHA).

A recent study conducted by researchers at the University of California, San Diego School of Medicine and the University of Hawaii demonstrates a new approach to measuring early brain development of infants, resulting in more accurate whole brain growth charts and providing the first estimates for growth trajectories of subcortical areas during the first three months after birth. Assessing the size, asymmetry and rate of growth of different brain regions could be key in detecting and treating the earliest signs of neurodevelopmental disorders, such as autism or perinatal brain injury.

Study demonstrates that the immune system can produce cells with stem cell properties that can create different types of cells such as neurons in the adult animal. Researchers have strived for years to determine how neurons are produced and integrated into the brain throughout adult life. In an intriguing twist, scientists reporting in the August 11 issue of the Cell Press journal Developmental Cell provide evidence that adult-born neurons are derived from a special type of circulating blood cell produced by the immune system.

While neurons normally fail to regenerate after spinal cord injuries, neurons formed from human induced pluripotent stem cells (iPSCs) that were grafted into rats with such injuries displayed remarkable growth throughout the length of the animals’ central nervous system. What’s more, the iPSCs were derived from skin cells taken from an 86-year-old man. The results, described in the Cell Press journal Neuron, could open up new possibilities in stimulating neuron growth in humans with spinal cord injuries.

A stroke therapy using stem cells extracted from patients' bone marrow has shown promising results in the first trial of its kind in humans. Five patients received the treatment in a pilot study conducted by doctors at Imperial College Healthcare NHS Trust and scientists at Imperial College London. The therapy was found to be safe, and all the patients showed improvements in clinical measures of disability.

While diabetes rates are on the rise and are having serious effects on millions of people’s health, researchers studying grizzly bears have now discovered a natural state of diabetes that serves a real biological purpose and is also reversible. The research reveals how natural biology, through evolutionary experimentation, can teach us new things about how animals naturally cope with conditions that would cause disease in humans.
