2008 Press Releases

  • Exercise Suppresses Appetite By Affecting Appetite Hormones

    Released December 11, 2008 - A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study. Taken together, the research shows that aerobic exercise is better at suppressing appetite than non-aerobic exercise and provides a possible explanation for how that happens.
  • Fructose Sets Table For Weight Gain Without Warning

    Released October 16, 2008 - Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats. Although previous studies have shown that being leptin resistant can lead to rapid weight gain on a high-fat, high-calorie diet, this is the first study to show that leptin resistance can develop as a result of high fructose consumption. The study also showed for the first time that leptin resistance can develop silently, that is, with little indication that it is happening.
  • Anabolic Steroids Still Provide a Competitive Edge in Power Lifting Even Years After Doping Has Ended

    Release September 25, 2008 - Anabolic steroids are synthetic hormones derived from the human male hormone testosterone. The use of steroids has been suspected in professional baseball and other sports where building muscle strength, rather than endurance, is paramount. Power lifting is such a sport. A team of researchers has examined the impact of anabolic steroid use on power lifters years after the athletes had ceased to take the drugs. The researchers found that while physical traces of the drug no longer remained, changes in the shoulder and quadriceps still gave lifters an advantage years later.
  • For Overweight Patients With Insulin Sensitivity, Even One Session Of Exercise Can Improve Metabolic Health

    Released September 25, 2008 - One out of every three Americans is obese. These individuals are at greater risk for additional diseases, since obesity leads to other health problems, such as diabetes. A team of researchers has examined the effect of exercise on fat accumulation in a new study involving five obese women. In one session the women overate and did not exercise; in a follow-on session they overate and did exercise. The findings indicate that even one bout of exercise helps to reduce the fat by-products inside the muscle, which affects the insulin sensitivity.
  • Substance Found In Fruits And Vegetables Reduces Likelihood Of The Flu

    Released September 3, 2008 - Mice given quercetin, a naturally occurring substance found in fruits and vegetables, were less likely to contract the flu. The study also found that stressful exercise increased the susceptibility of mice to the flu, but quercetin canceled out that negative effect.
  • Testing for Recombinant Human Erythropoietin (rHuEpo)

    Released June 26, 2008 - Recombinant human erythropoietin (rHuEpo) is a genetically engineered hormone sometimes misused by high-performance athletes such as cyclists and marathon runners to boost their endurance. The potential misuse of the drug is detected in urine collected from athletes. Since the test was introduced in 2000, 33 labs around the world have been accredited by the World Anti-Doping Agency (WADA) to administer the procedure. During the last few years, the testing procedure has been criticized by some. Accordingly, a team of researchers investigated the quality of the test results at two WADA labs. They found that the detection power of the test at the two labs was poor.
  • Lifestyle Can Alter Gene Activity, Lead to Insulin Resistance

    Released June 18, 2008 - A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy. The findings suggest that lifestyle, more than heredity, contributes to insulin resistance in people who are obese.
  • Ingredient Found In Green Tea Significantly Inhibits Breast Cancer Growth In Female Mice

    Released April 7, 2008 - A new study conducted by researchers at the University of Mississippi researchers now finds that consuming EGCG, an antioxidant found in green tea, significantly inhibits breast tumor growth in female mice.
  • Treatment With An Antipsychotic Drug Found To Cause Changes In Metabolism Earlier Than Expected

    Released April 7, 2008 - The second generation of antipsychotics – known as atypical antipsychotics (AAP) – began in 1990. These newer medicines have proven as effective in treating the positive aspects of the disease and more effective in combating the negative ones.
  • Specialized Nasal Sensory Cells Detect Irritants In The Environment

    Released March 4, 2008 - Many chemicals, including most odorants in highly concentrated form, are irritating to the nose and can cause burning, stinging, warmth, itching or pain. The sensations occur when high levels of the chemical odors activate the trigeminal sensory system in the nasal cavity. It is not yet known how the initial process occurs but a small, important step towards understanding it has been made.
  • A Human Hormone Blocker is Found to Help Prevent Obesity & Diabetes During Animal Testing

    Released January 3, 2008 - A new study finds that a chemical found in the body is capable of promoting weight loss, improving insulin resistance and reversing diabetes in an animal model. The hormone is gastric inhibitory polypeptide (GIP) receptor blockade.
