Animal Findings Suggest That Gender May Influence Bisphenol A Chemical Exposure Risks For Humans
Date: Feb-14-2013Parents, teachers and psychologists know boys and girls behave differently. However, that difference isn't taken into account by most methods used to assess the risk to children from chemical exposure, according to Cheryl Rosenfeld, associate professor of biomedical sciences in the University of Missouri's Bond Life Sciences Center...
New Technique Could Revolutionize The Field Of Medical Imaging
Date: Feb-14-2013Researchers from the Institute of Photonic Sciences (ICFO), in collaboration with the CSIC and Macquarie University in Australia, have developed a new technique, similar to the MRI but with a much higher resolution and sensitivity, which has the ability to scan individual cells. In an article published in Nature Nanotech, and highlighted by Nature, ICFO Prof. Romain Quidant explains how this was accomplished using artificial atoms, diamond nanoparticles doped with nitrogen impurity, to probe very weak magnetic fields such as those generated in some biological molecules...
Three-Week Auditory Training Regimen Aids Comprehension In Hearing-Impaired Children
Date: Feb-14-2013Children with hearing loss struggle to hear in noisy school classrooms, even with the help of hearing aids and other devices to amplify their teacher's voice. Training the brain to filter out background noise and thus understand spoken words could help the academic performance and quality of life for children who struggle to hear, but there's been little evidence that such noise training works in youngsters. A new report showed about a 50 percent increase in speech comprehension in background noise when children with hearing impairments followed a three-week auditory training regimen...
Link Between Obesity, Excess Weight Gain During Pregnancy And Heavier Babies In African-American Women
Date: Feb-14-2013Epidemiologists at Boston University School of Public Health (BUSPH) have found that pre-pregnancy obesity and excess weight gain during pregnancy in African-American women are associated with an increased risk of giving birth to an abnormally large baby. Macrosomia, which is defined as a newborn weighing more than 4,000 grams at birth (approximately 8.8 pounds), can cause delivery complications such as hemorrhage, infection, the need for a caesarean section, preeclampsia and perinatal mortality...
Possible Alternative Treatment To Significantly Reduce The Adverse Effects Of Chemotherapy In Lymphoid Leukemia
Date: Feb-14-2013An international research team coordinated at the IRCM in Montréal found a possible alternative treatment for lymphoid leukemia. Led by Dr. Tarik Möröy, the IRCM's President and Scientific Director, the team discovered a molecule that represents the disease's "Achilles' heel" and could be targeted to develop a new approach that would reduce the adverse effects of current treatments such as chemotherapy and radiation therapy. The study's results are being published in the prestigious scientific journal Cancer Cell...
HIV, Ebola, Other Deadly Viruses Blocked By Newly Identified Natural Protein
Date: Feb-14-2013A team of UCLA-led researchers has identified a protein with broad virus-fighting properties that potentially could be used as a weapon against deadly human pathogenic viruses such as HIV, Ebola, Rift Valley Fever, Nipah and others designated "priority pathogens" for national biosecurity purposes by the National Institute of Allergy and Infectious Disease...
African-American Women With Benign Breast Disease May Be At Greater Risk For Cancer
Date: Feb-14-2013A Wayne State University researcher has identified characteristics in benign breast disease associated with future cancer risk in African-American women. Michele Cote, Ph.D., associate professor of oncology in the School of Medicine and the Barbara Ann Karmanos Cancer Institute, recently reviewed data from about 1,400 20- to 84-year-old African-American women who underwent breast biopsies between 1997 and 2000. Researchers identified biopsies that showed benign breast disease (BBD) and also tracked subsequent breast cancers...
Dance-Related Injuries Increase In Children And Adolescents
Date: Feb-14-2013Dance is a beautiful form of expression, but it can be physically taxing and strenuous on the human body, particularly for children and adolescents. A new study by researchers at the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital examined dance-related injuries among children and adolescents 3 to 19 years of age from 1991 to 2007. During the 17-year study period, an estimated 113,000 children and adolescents were treated in U.S. emergency departments for dance-related injuries...
Prompt Identification And Therapies Can Improve Outcomes In Perioperative Stroke
Date: Feb-14-2013Strokes that occur during or shortly after surgery can be devastating, resulting in longer hospital stays and increased risks of death or long-term disability. But prompt identification and treatment of such strokes can improve neurologic outcomes, according to an article in the journal Expert Review of Neurotherapeutics by Loyola University Medical Center stroke specialists Sarkis Morales-Vidal, MD and Michael Schneck, MD. The article answers commonly asked questions about the management of perioperative stroke...
Vitamin C Helps Marathon Runners Reduce Risk Of Catching A Cold
Date: Feb-13-2013An updated review of placebo-controlled trials on Vitamin C and the common cold finds the vitamin may help people under heavy physical stress, such as marathon runners and skiers, to reduce their risk of catching a cold. As for the rest of the population, the review finds no evidence that regular supplementation of vitamin C reduces the chance of coming down with a common cold, although it may reduce the duration and severity of illness. The review appears in the 31 January issue of The Cochrane Library...
