  • Still a Champion Runner at 80: Do Elite Athletes Have an Anti-Aging Secret in Their Muscles?

    Released December 22, 2015 - Elite runners do not experience the muscle weakening associated with aging as non-athletes do. A new study published in American Journal of Physiology—Cell Physiology examines if their superb fitness is because their muscles have not aged.
  • Carbs, Not Fats, Boost Half-Marathon Race Performance, Study Finds

    Released December 15, 2015 - Recent studies have proposed that burning fat instead of carbohydrates will improve exercise performance because the body's fat reserve is much larger than its carbohydrates reserve. A new study in Journal of Applied Physiology reports the opposite, finding that muscles rely on carbohydrates as their fuel source during prolonged exercise.
  • Study Links Environmental and Lifestyle Factors to Reproductive Problems, Infertility in Men

    Released December 10, 2015 - Environmental and lifestyle factors are damaging men’s reproductive health and may be playing a large role in decreasing fertility rates in industrialized countries, a new study in Physiological Reviews reports. Socioeconomic influences and female reproductive health cannot solely be blamed for higher incidences of infertility, the study supports.
  • Study Suggests New Strategy for Treating Rare Neurodegenerative Disorder Menkes Disease

    Released December 1, 2015 - Menkes disease arises from dysfunction in ATP7A, a protein that transports copper to cells, leading to brain development complications. Introducing working versions of ATP7A in the brain is considered the most direct therapeutic approach. However, a new study in AJP-Cell suggests that functioning ATP7A located elsewhere in the body, not necessarily the entire brain, can help treat the disorder. This research is highlighted as one of this month’s “best of the best” as part of the American Physiological Society’s APSselect program.
  • When Exercise Is Unhealthy for the Heart: Researchers Describe How Heart Problems and Sudden Cardiac Death Occur with Endurance Exercise

    Released November 25, 2015 - Endurance exercise accelerates the development of heart problems in individuals with a particular genetic mutation, a new study finds.

    Released November 20, 2015 - Preeclampsia is generally diagnosed later in pregnancy, but new research reports that the protein copeptin can predict the development of preeclampsia as early as six weeks of gestation. The findings could lead to diagnosis of the disorder in the first trimester, improving care and potentially leading to the development of preventative measures.
  • Children Born to Women after Bariatric Surgery at Higher Risk of Obesity, Diabetes

    Released November 19, 2015 - Weight-loss surgery can boost fertility in women and reduce the risk of pregnancy complications that commonly occur in obese women. However, a new study in rats suggests that weight-loss surgery alters mothers’ hormone and chemical balance, which harms offspring during gestation and later in life.
  • Sex Reassignment Surgery May Be Better for Transgender Women’s Health than Hormones Only

    Released November 18, 2015 - Transgender women may be at a higher risk of developing cardiovascular disease and type 2 diabetes compared with men and women in the general population. New research finds that transgender women who received only hormone therapy had poorer metabolic health than transgender women who underwent sex reassignment surgery in addition to receiving hormone therapy, suggesting that sex reassignment surgery may be metabolically protective.
  • Is Testosterone Therapy Safe?

    Released November 18, 2015 - The increasing use of testosterone replacement therapy to treat reduced testosterone level in older men has been accompanied by growing concerns over its long-term safety. Two studies examining the health risks of receiving testosterone will be presented at Cardiovascular, Renal and Metabolic Diseases: Physiology and Gender conference, supporting opposite conclusions regarding risks.
  • Male Hormone Testosterone Cause of Sex Differences in Parkinson’s Disease Risk, Study Suggests

New research suggests that testosterone enhances the susceptibility of brain cells that control movement to damage from chemical imbalances, explaining the sex differences in the occurrence of Parkinson’s.
  • Genes May Determine the Side Effects of Menopausal Hormone Therapy, Study Suggests

    Released November 10, 2015 - Cardiovascular disease risk in women increases after menopause and is associated with the drop in estrogen levels.

However, a new clinical study finds that age may be more important for long-term transplant and patient outcome.
  • Mechanical Ventilators: From Breathing Help to Breathing Handicap

    Released September 10, 2015 - Researchers explore cell-level changes that weaken the diaphragm after prolonged ventilator use Abstract: Mechanical ventilators are routinely used in both surgical and emergency situations every day in U.S. hospitals. Though often life saving in the short term, prolonged use of ventilators can lead to diaphragm weakness, and problems commonly arise—roughly 20 to 30 percent of the time—when weaning the patient off of the ventilator. In a new study, researchers at the University of Florida provide insights into what causes the weakness on a cellular level. Their result could lead to strategies that hospitals can use to help prevent ventilator-related diaphragm damage.
  • High-Intensity Training Delivers Results for Older Men—But Not for Older Women

    Released September 10, 2015 - High intensity training (HIT) is often recommended as a way to improve cardiovascular fitness in men and women, however, studies on these exercise regimens have focused on younger subjects. University of Copenhagen researchers looked at HIT effects in older males and females and found significant differences between men and women. They presented their results at the Physiological Bioenergetics conference in Tampa, Fla.

    Released July 1, 2015 - Long-term use of naproxen (ALEVE), a type of nonsteroidal anti-inflammatory drugs (NSAIDs), is often prescribed for chronic pain conditions such as osteoarthritis. However, because of NSAID-related gastrointestinal problems including stomach and intestinal inflammation and ulcers, many are unable to tolerate ongoing use. A new study, published in the American Journal of Physiology–Gastrointestinal and Liver Physiology, finds that a naproxen-derivative may provide both symptom relief and gastrointestinal protection. The research is highlighted as one of this month’s “best of the best” as part of the American Physiological Society’s APSselect program.
