Oral medications must reach the bloodstream
Date: Aug-30-2013All too often, when a person takes a pill full of a potent and effective drug, the drug passes straight through the body, not reaching the organ where it is needed - a waste of money and inconvenient if it is a cold medicine, but potentially dire if it is a treatment for a serious illness. Polymer chemists at Virginia Tech and pharmaceutical scientists at Purdue University have teamed up to design a solution...
Underrepresentation in HIV studies not due to conspiracy theories
Date: Aug-30-2013Even though most Americans believe some kind of conspiracy theory about HIV care and research, many are willing to take part in vaccine trails, according to a new study¹ by Ryan Westergaard of the University of Wisconsin School of Medicine and Public Health, published in Springer's Journal of General Internal Medicine². The study found no link between distrust in medical research and willingness to participate in related studies. Westergaard and his team asked 601 Chicago residents at various shopping centers to voluntarily complete a set of 235 questions...
Women urged to maintain periodontal health during pregnancy
Date: Aug-30-2013When a woman becomes pregnant, she knows it is important to maintain a healthy lifestyle to ensure both the health of herself and the health of her baby. New clinical recommendations from the American Academy of Periodontology (AAP) and the Eurpean Federation of Periodontology (EFP) urge pregnant women to maintain periodontal health as well. Research has indicated that women with periodontal disease may be at risk of adverse pregnancy outcomes, such giving birth to a pre-term or low-birth weight baby, reports the AAP and EFP...
Alcohol consumption prior to first pregnancy linked to greater risk of BBD & breast cancer
Date: Aug-30-2013Drinking alcohol before first pregnancy is associated with an increased risk of benign breast disease (BBD) and breast cancer, independent of drinking after first pregnancy, according to a new study published August 28 in the Journal of the National Cancer Institute. Previous studies have shown that alcohol consumed in the past year affects a woman's breast cancer risk. However, data on the relationship between drinking alcohol during the period of time between a woman's first menstrual period and first pregnancy and the risk of proliferative BBD and breast cancer had not been reported...
In autism, difficulty understanding visual cues and sounds often clears during adolescence
Date: Aug-30-2013Scientists at Albert Einstein College of Medicine of Yeshiva University have shown that high-functioning autism spectrum disorder (ASD) children appear to outgrow a critical social communication disability. Younger children with ASD have trouble integrating the auditory and visual cues associated with speech, but the researchers found that the problem clears up in adolescence. The study was published in the online edition of the journal Cerebral Cortex. "This is an extremely hopeful finding," said lead author John Foxe, Ph.D., professor of pediatrics and in the Dominick P...
Overwhelmingly Positive Depictions of Alcohol Use in Songs Popular Among Youth
Date: Aug-30-2013Four alcohol brands - Patron tequila, Hennessy cognac, Grey Goose vodka, and Jack Daniel's whiskey - accounted for more than half of alcohol brand mentions in the songs that mentioned alcohol use in Billboard's most popular song lists in 2009, 2010 and 2011, according to a new study from researchers at the Boston University School of Public Health and the Center on Alcohol Marketing and Youth (CAMY) at the Johns Hopkins Bloomberg School of Public Health...
Researchers uncover a major cause of age-related memory loss
Date: Aug-30-2013A team of Columbia University Medical Center (CUMC) researchers, led by Nobel laureate Eric R. Kandel, MD, has found that deficiency of a protein called RbAp48 in the hippocampus is a significant contributor to age-related memory loss and that this form of memory loss is reversible. The study, conducted in postmortem human brain cells and in mice, also offers the strongest causal evidence that age-related memory loss and Alzheimer's disease are distinct conditions. The findings were published in the online edition of Science Translational Medicine...
The height-IQ connection
Date: Aug-30-2013The fact that taller people also tend to be slightly smarter is due in roughly equal parts to two phenomena - the same genes affect both traits and taller people are more likely than average to mate with smarter people and vice versa - according to a study led by the University of Colorado Boulder. The study did not find that environmental factors contributed to the connection between being taller and being smarter, both traits that people tend to find attractive. The modest correlation between height and IQ has been documented in multiple studies stretching back to the 1970s...
Sleep apnea sufferers may benefit from new surgical tool

What is poison ivy? What is a poison ivy rash?
Date: Aug-30-2013Poison ivy is a plant well known for causing severe inflammation of the skin, also known as contact dermatitis. The plant contains a sap which causes instant irritation if it comes in contact with the skin. Poison ivy is native to North America, where it mainly grows in clusters on the edges of woodland - where there is sufficient sunlight for it to grow. The plant is characterized by clusters of three leaflets, which can range from light green to dark green, each growing on its own stem, connected to a main vine (without any thorns)...
