Bringing hope to hundreds of children in one of the countries hardest hit by HIV/AIDS, the Abbott Fund, Baylor College of Medicine and the Government of Malawi have joined forces to build the country’s first pediatric HIV clinic. The First Lady of Malawi, Madame Ethel Zvauya Mutharika and other dignitaries at Kamuzu Central Hospital officially opened the new clinic today in the city of Lilongwe.
Governor Mike Huckabee of Arkansas and Pfizer Inc today announced the formation of Balance It Out: Arkansas, a new school-based community program to reduce the number of children who are overweight or at risk of becoming overweight, effectively diminishing their risk of developing chronic illness. In December 2006, the program will begin in Little Rock, AR, with a health fair for state employees designed to increase awareness of health risk factors and steps to prevent disease. Beginning in early 2007, the program will reach children and their families in the Dollarway (Pine Bluff), Harrison and Paragould school districts.
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules. Cell adhesion controls many aspects of brain development including growth and structure, and enables neurons to connect with other neurons and supportive proteins. Differences in the molecular connections of human neurons compared to the neurons of chimps, mice and other animals, could help explain why the human brain is capable of far more complex cognitive functions.
When a portion of a zebrafish’s heart is removed, the dynamic interplay between a mass of stem cells that forms in the wound and the protective cell layer that covers the wound spurs the regeneration of functional new heart tissue, Duke University Medical Center scientists have found.
New evidence to explain how a common tropical fish mends a broken heart may suggest methods for coaxing the damaged hearts of mammals to better heal, researchers report. The researchers found that the hearts of zebrafish harbor progenitor cells that spring into action to restore wounded heart muscle. Cells from a membrane layer that surrounds the heart, called the epicardium, follow suit, invading the wounded cardiac tissue and stimulating the growth of new blood vessels.
Doctors should probably stop using pulmonary artery catheters because they do not benefit patients, say doctors from Australia in this week’s BMJ.
New research shows that higher levels of uric acid are strongly associated with high blood pressure in blacks, suggesting that a simple blood test could predict risk and that treatments to lower uric acid may be a novel way to reduce hypertension-related complications in this population.
A new model based on specific characteristics of the donor and the recipient may help predict survival after liver transplantation, according to a new study. Published in the November 2006 issue of Liver Transplantation, the official journal of the American Association for the Study of Liver Diseases (AASLD) and the International Liver Transplantation Society (ILTS), the author writes, “This model could be used to inform liver transplant candidates and their doctors what post-transplant survival would be expected when a given donor is offered and may be particularly helpful in marginal or high risk donors.”
A new study by scientists at the MUHC has revealed that a diet low in folate may increase the risk of developing colorectal cancer. Published in the scientific journal Cancer Research today, the study not only illustrates a way to prevent the disease but also provides further insight into the mechanisms of the disease, which could lead to novel therapies. Using animal models, the MUHC study is the first to demonstrate directly that diets low in folate cause colorectal cancer, and follows on the heels of earlier research by the same team that revealed how high folate diets can protect against heart disease.
An interdisciplinary research team led by Dr. Joe Cannon (third from right) will examine the effects of follicle stimulating hormone on white blood cells. Future studies may lead to alternatives… Click here for more information. Regulating a hormone abundant in women approaching menopause could offer alternatives for hormone replacement therapy, Medical College of Georgia researchers say.
