A research paper published in the November 2006 edition of BJOG: An International Journal of Obstetrics and Gynaecology reveals seasonal and environmental variations can result in higher incidences of premature births.
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.
A team of researchers has used computer simulations to explain how cells adhere so firmly to blood vessel walls.
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons — critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease).
Preliminary findings from a University of Florida study show there is little difference in the dose of general anesthesia needed to anesthetize patients in weightless or normal gravity environments. It’s a step forward, but just one of many hurdles researchers face in trying to establish proper medical protocols in space.
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.
Georgia Tech/Emory researchers have integrated dopamine, a type of neurotransmitter, into a polymer to stimulate nerve tissues to send out new connections. The discovery, published in PNAS, is the first step toward the eventual goal of implanting the polymer into patients suffering from neurological disorders to help repair damaged nerves.
Ohio State University chemists have devised a new way to create tiny molecular rings that could one day function as drug delivery devices or antibiotics. The rings are made from polymers — large molecules that are made up of many smaller molecules — and the chemical reaction that creates them is similar to others that create polymer chains. But this new reaction solely makes rings, ones tailored to perform specific functions.
A breakthrough finding on the mechanism of myelin formation by Jonah Chan, assistant professor of cell and neurobiology at the Keck School of Medicine of the University of Southern California, could have a major impact on the treatment of diseases such as multiple sclerosis and demyelination as a result of spinal cord injuries.
Researchers have found a highly unusual distribution of two proteins in the lungs and airways of people with cystic fibrosis, a discovery that could be a step in determining how the disease progresses. The proteins, first uncovered as a result of the human genome project, are thought to play a role in the body’s immune system.
