Tampa, FL (Oct. 8, 2008) – Women, the elderly, and patients admitted to the emergency department on weekends are all less likely to receive same-day coronary angioplasty for a life-threatening heart attack in Florida, University of South Florida researchers found. Their study was published this month (Oct. 1) in the American Journal of Cardiology.

A new study uncovers a previously unrecognized, species-specific impact of circadian rhythms on the production of mobilized stem cells. The research, published by Cell Press in the October 9th issue of the journal Cell Stem Cell, suggests that when it comes to collecting human stem cells for clinical transplantation, picking the right time of day to harvest cells may result in a greater yield.

STANFORD, Calif. - A family of cancer-fighting molecules helps blood stem cells in mice decide when and how to divide, say researchers at the Stanford University School of Medicine. Blocking the molecules' function spurs the normally resting cells to begin proliferating strangely - making too much of one kind of cell and not enough of another. Many types of human blood cancers involve a similar disruption in the expression of that same family of molecules.

CHAPEL HILL – More people suffer from pain than from heart disease, diabetes and cancer combined, but many of the drugs used to relieve suffering are not completely effective or have harmful side effects.

Now researchers at the University of North Carolina at Chapel Hill School of Medicine and the University of Helsinki have discovered a new therapeutic target for pain control, one that appears to be eight times more effective at suppressing pain than morphine.

Montréal, October 9, 2008 – A research team at the Institut de recherches cliniques de Montreal (IRCM), funded by the Foundation Fighting Blindness – Canada and the Canadian Institutes of Health Research (CIHR), discovered a novel mechanism that regulates how neural stem cells of the retina generate the appropriate cell type at the right time during normal development. These findings, published today in the renowned journal Neuron, could influence the development of future cell replacement therapies for genetic eye diseases that cause blindness.

AUSTIN, Texas – A novel delivery system that could lead to more efficient and more disease-specific vaccines against infectious diseases has been developed by biomedical engineers at The University of Texas at Austin.

The findings use specific ribonucleic acid (RNA) molecules to significantly bolster a vaccine's effectiveness while tailoring it based on the type of immune response that is most desirable for a particular disease, says Krishnendu Roy, associate professor of biomedical engineering and lead investigator on the study.

MADISON — An anticipated increased incidence of climate-related extreme rainfall events in the Great Lakes region may raise the public health risk for the 40 million people who depend on the lakes for their drinking water, according to a new study.

Austin, TX – October 8, 2008 – A new study in the journal Analyses of Social Issues and Public Policy explored elementary-school-age children's views about the role of race and gender in the U.S. presidency, Results indicated that most children are aware that women and people of color have been excluded from the presidency. Further, many children attributed the lack of female, African American, and Latino presidents to gender and racial discrimination.

Reston, Va.—Two things happen following a heart attack—necrosis (normal cell death) and apoptosis (programmed cell death)—and both are bad. Now researchers in Japan have found that a single intravenous dose of the hormone erythropoietin (EPO) immediately after myocardial infarction (heart attack) can drastically reduce or eliminate apoptosis and thereby limit the amount of damage to the heart, according to an article in the October issue of The Journal of Nuclear Medicine.

CINCINNATI—Exposure to bisphenol A (BPA) may reduce the effectiveness of chemotherapy treatments, say University of Cincinnati (UC) scientists.

The research study, led by UC's Nira Ben-Jonathan, PhD, says that BPA—a man-made chemical found in a number of plastic products, including drinking bottles and the lining of food cans—actually induces a group of proteins that protect cancer cells from the toxic effects of chemotherapy.

The findings are reported in the journal Environmental Health Perspectives and appear online Oct. 8, 2008, ahead of print.

CHICAGO – Breast augmentation, lift, combination lift/augmentation and reduction achieve high satisfaction rates; enhance self-esteem and quality of life; and 99 percent of women would have their surgery again, according to a first-of-its-kind study to be presented at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2008 conference, Oct. 31 – Nov. 5, in Chicago. The study found breast lift and lift/augmentation to have a high level of patient satisfaction that rivals breast augmentation and reduction.

CHICAGO – Injecting fat after breast reconstruction to correct implant wrinkling or dimpling may be safe and effective to improve breast shape, according to a study to be presented at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2008 conference, Oct. 31 – Nov. 5, in Chicago. Using fat injections for cosmetic breast enhancement; however, is still controversial and will be the subject of a panel discussion.

CHICAGO – The importance of pre-operative screening for patients seeking body contouring after massive weight loss will be assessed in three studies presented at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2008 conference, Oct. 31 – Nov. 5, in Chicago. These studies examine demographic factors that could affect complication rates; specifically, those who have not yet attained their goal body mass index (BMI); those who lost weight through diet and exercise and those who are male.

CHICAGO – Women who desire a mommy-makeover, have had major weight loss, or are unhappy with the toll age has taken on their breasts can breathe easier. An innovative procedure to correct severely deflated, sagging breasts left looking like "pancakes" will be presented at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2008 conference, Oct. 31 – Nov. 5, in Chicago. The procedure corrects misshapen breasts by lifting and restoring them to a more natural, full shape and position without the use of breast implants.

CHICAGO – Imagine not having the ability to return the smile of a loved one or being too embarrassed by your mouth's appearance to display a smile. At the American Society of Plastic Surgeons (ASPS) and American Society of Maxillofacial Surgeons (ASMS) Plastic Surgery 2008 conference, Oct. 31 – Nov. 5, in Chicago, plastic surgeons or "smile doctors" will reveal state-of-the-art "facial reanimation" procedures that give people, who previously were unable, the ability to smile. Additionally, ways to rejuvenate an aged smile and enhance the often overlooked mouth region will be discussed.
