  • Is Testosterone Replacement Therapy Safe For Aging Men?

    Released August 8, 2007 - For decades, older women have taken hormone replacements to replenish estrogen and progesterone levels lost to aging. More recently, testosterone (the most important male hormone) supplements have been used by aging men to improve their muscle mass, bone strength, libido and quality of life. The increased use has occurred despite the fact that the cardiovascular effects of chronic testosterone treatment in aging males are largely unknown, and the safety of testosterone replacement has not been evaluated. Researchers are using an animal model to examine potential links between testosterone supplements, and cardiovascular and renal disease.
  • Hormone That Signals We Are Full When Eating Also Curbs Fast Food Consumption And Tendency To Binge Eat

    Released June 7, 2007 - The synthetic form of a hormone previously found to produce a feeling of fullness when eating and reduce body weight, also may help curb binge eating and the desire to eat high-fat foods and sweets. The findings on fast food consumption and binge eating tendencies are based on a 6-week research study of 88 obese individuals.
  • Lap Band Gastric Bypass Surgery Improves Insulin Resistance

    Released May 1, 2007 - A new study examining the overall and gender-related effects of laparoscopic gastric banding surgery on insulin resistance, body composition, and metabolic risk markers six months after surgery has found significant improvements in insulin resistance.
  • Physical Fitness Reduces Hypertensive Influence Of Leptin On Blood Pressure, Regardless Of Body Fat

    Released April 30, 2007 - Regular physical activity counts more than percentage of body fat in terms of systolic blood pressure - a measure of how hard the body has to work to pump blood against the resistance of the blood vessel walls.
  • Your Brain And Hormones May Conspire To Make You Fat

    Released April 30, 2007 - Physiologists are unraveling the role that hormones and the brain play in urging you to eat more than you should. Some people’s hormones may be signaling their brains to send messages like “Eat a lot now,” and “Go for the fat and sugar.”
  • Oxford Physiology Professor Earns Walter B. Cannon Award

    Released April 25, 2007 - While the subject of ion channels might seem abstract, these microscopic gates into individual cells can account for some astonishing phenomena: goats that fall flat on the ground when startled; pigs that shiver themselves to death; horses that suffer bouts of paralysis. Each of these conditions was traced to a malfunctioning ion channel. Oxford University Physiology Professor Frances M. Ashcroft, working with Exeter University Professor Andrew Hattersley, discovered another malady associated with ion channel malfunction: a rare genetic form of diabetes that strikes children and is known as permanent neonatal diabetes mellitus. The scientists’ discovery produced dramatic changes in the lives of children born with the disease. As a result of their research, these children have been able to switch from daily insulin injections to a daily pill, transforming both their lives and that of their parents. APS will present its highest award to Dr. Ashcroft.
  • Like Salty Food? Chances Are You Had Low Blood Sodium When You Were Born
