2007 Press Releases


  • Expecting an Afternoon Nap Can Reduce Blood Pressure

    Released October 15, 2007 - Where does the benefit lie in an afternoon nap? Is it in the nap itself, or in the anticipation of taking a snooze? Researchers in the United Kingdom have found that the time just before you fall asleep is where beneficial cardiovascular changes take place.
  • Gender, Coupled With Diabetes, Affects Vascular Disease Development

    Released August 15, 2007 - Diabetes is associated with the development of vascular (blood vessel) disease. As we age, vascular disease becomes more common. It has been thought that females may be more susceptible to the earlier development of vascular disease, as vascular changes are observed in females long before any significant development occurs in males. Now, a team of Georgetown University researchers has determined that the vascular activities in diabetic animals vary according to sex. This discovery may eventually have implications for the way males and females are treated medically in the future.
  • Cardio Exercise Benefits In Male Vs. Female Hearts

    Released August 8, 2007 - While cardiovascular disease occurs in both men and women, it does not affect them in the same way. Risk factors and protective factors for heart diseases are likewise unequal. The molecular mechanisms responsible for these differences are so far unknown, but some believe it is due to chromosomal linked genes or sexual hormones such as estrogen and testosterone. While the mechanisms behind the differences are unknown, the physiological differences are clear. A new study examining chronic exercise in male and female mice finds that moderate long-term exercise provokes a sex-dependent cardiac adaptation that is different for females versus males. The findings may eventually help improve treatment strategies for women and men with heart disease.
  • Estrogen Deficiency Can Lead To Obesity-Induced Hight BP After Menopause

    Released August 8, 2007 - At menopause, women lose hormone protection against heart (cardiovascular) and kidney diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity. The results of their study, using an animal model, suggest that estrogen depletion can have these effects.
  • Gender Differences In Renal And Other Genes Contribute To BP

    Released August 8, 2007 - In a new study, researchers examined the differential contribution of genetic factors involved in regulating blood pressure based on samples drawn from a large community. They found significant differences in genetic contributors to blood pressure in males versus females.
  • Why Do Men And Women Respond Differently To The Same Disease?

    Released August 8, 2007 - More than 100 research scientists will examine hormones, gender and how they can interact to cause heart and kidney disease. The conference, entitled Sex and Gender in Cardiovascular-Renal Physiology and Pathophysiology, being held August 9-12, 2007 in Austin, TX, is hosted by the American Physiological Society.
  • Eight Plants From South Africa May Hold Potential For Treating High Blood Pressure

    Released May 1, 2007 - Medicinal plants are an integral part of African culture, one of the oldest and most diverse in the world. In South Africa, 21st century drug therapy is used side-by-side with traditional African medicines to heal the sick. While plants have been used in African medicine to treat fever, asthma, constipation, and hypertension, scientific analyses of the purported benefits of many plants is still scant. A team of researchers has now examined the effectiveness of 16 plants growing in the country’s Kwa-Zulu Natal region and concluded that eight plant extracts may hold value for treating high blood pressure.
  • Short-Term Use Of Statin Drugs Reduces Damaging Sympathetic Nervous System Overactivity In Heart Failure Patients

    Released May 1, 2007 - One of the first studies to examine the effect of the popular statin (cholesterol) drugs on the sympathetic nervous system activity of human patients with heart failure.
  • 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.
  • Peptide Regulates Social Behavior, Has Positive Impact On Cardiac Response

    Released April 29, 2007 - A team of researchers investigating the effects of oxytocin, a peptide produced by the brain that regulates social behavior, has found that it can prevent detrimental cardiac responses in adult female animals exposed to social isolation. The findings may provide further insight into how these mechanisms affect humans.
  • University Of Texas Researcher Earns APS Bowditch Award

    Released April 25, 2007 - James D. Stockand, a researcher at the University of Texas Health Science Center at San Antonio, studies epithelial sodium channels in the cells of the kidney, lungs and colon. His research may lead to a better understanding of how these cells regulate salt and could one day be used to control hypertension.
  • The “Elvis Experiments”

    Released April 24, 2007 - More than 100 Washington-area high school students and teachers are participating in “The Elvis Experiments.” The experiments, named in honor of “the King,” were designed by educators at the American Physiological Society to help students participate in hands-on demonstrations aimed at showing the different factors that influence blood flow and blood pressure.
  • Taking the Fight Against Cancer to Heart

    Released February 26, 2008 - Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to a new study.
  • Active Ingredient In Common Chinese Herb Shown To Reduce Hypertension

    Realeased January 17, 2007 - Many patients with high blood pressure have consumed danshen, a Chinese herb used in Oriental medicine that promotes blood flow and treats cardiovascular disease. Tanshinone IIA is an active ingredient of danshen. In a new study using an animal model, the scientists have found that tanshinone IIA does reduce blood pressure.
