• Exposure to Alcohol Before Birth May Make Drinking More Appealing to Teens:  A new study suggests that fetal alcohol exposure (FAE) reduces the taste system’s responsiveness to the bitter flavor and burning sensation of many varieties of alcoholic beverages. These factors make alcohol unappealing to some people, but, for reasons that are unclear, are less of a deterrent in young people exposed to alcohol before birth. The study is published ahead of print in the Journal of Neurophysiology.
  • Beetroot Juice May Provide Benefits to Heart Disease Patients:  A new study finds that dietary nitrate—a compound that dilates blood vessels to decrease blood pressure—may reduce overstimulation of the sympathetic nervous system that occurs with heart disease. The research team looked specifically at beetroot juice, a source of dietary nitrate, to explore its use as a future targeted treatment option for people with cardiovascular disease. The study, published ahead of print in the American Journal of Physiology—Heart and Circulatory Physiology, is the first to study the effects of nitrate supplementation on sympathetic nerve activity.
  • Prolonged Military-Style Training Causes Changes to Intestinal Bacteria, Increases Inflammation:  A new study finds that long periods of physiological stress can change the composition of microorganisms residing in the intestines (intestinal microbiota), which could increase health risks in endurance athletes and military personnel. The study, published ahead of print in the American Journal of Physiology—Gastrointestinal and Liver Physiology, is the first to study the response of the intestinal microbiota during military training. The manuscript was chosen as an APSselect article for May.
  • Can Aromatherapy Calm Competition Horses?:  Although studies suggest that inhaling certain scents may reduce stress in humans, aromatherapy is relatively unexplored in veterinary medicine. But new research presented today at the Experimental Biology 2017 meeting in Chicago raises the question of whether aromatherapy may be beneficial to horses as well.
  • Intense Training without Proper Recovery Raise Stress Fracture, Bone Loss Probability in Elite Rowers:  Bone mineral density, an indicator of bone strength, typically increases with regular exercise acting as a protective mechanism against bone fractures and osteoporosis. But a new study suggests that the extended, high-intensity training sessions of elite athletes could reverse beneficial bone changes. Researchers from Brock University in Canada will present their findings today at the Experimental Biology 2017 meeting in Chicago.
