Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases........ ]]> http://medicineworld.org/stories/lead/11-2009/research-study-on-near-vision.html http://medicineworld.org/stories/lead/11-2009/research-study-on-near-vision.html Fri, 06 Nov 2009 14:56:41 GMT The Cornea and Laser Eye Institute is participating in a research study to determine if an investigational corneal inlay can safely and effectively reduce the need for reading glasses. Dr. Peter Hersh, the study doctor, will perform the procedures. The investigational AcuFocus Corneal Inlay (ACI) is intended to improve near vision in patients with presbyopia, which is the loss of near vision, and reduce dependency on reading glasses. Qualified participants will receive the procedure at no charge........ ]]> http://medicineworld.org/stories/lead/11-2009/air-pollution-and-infants-bronchiolitis.html http://medicineworld.org/stories/lead/11-2009/air-pollution-and-infants-bronchiolitis.html Fri, 06 Nov 2009 14:56:41 GMT Infants who are exposed to higher levels of air pollution are at increased risk for bronchiolitis, as per a newly released study. The study appears in the November 15 issue of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine. "There has been very little study of the consequences of early life exposure to air pollution," said Catherine Karr, M.D. PhD, assistant professor of pediatrics at the University of Washington and the paper's main author. "This study is unique in that we were able to look at multiple sources including wood smoke in a region with relatively low concentrations of ambient air pollution overall"........ ]]> http://medicineworld.org/stories/lead/11-2009/nanoparticles-for-diagnosis.html http://medicineworld.org/stories/lead/11-2009/nanoparticles-for-diagnosis.html Fri, 06 Nov 2009 14:56:41 GMT Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade........ ]]> http://medicineworld.org/stories/lead/11-2009/how-the-heart-is-formed.html http://medicineworld.org/stories/lead/11-2009/how-the-heart-is-formed.html Fri, 06 Nov 2009 14:56:41 GMT While studying how the heart is formed, researchers at the University of Pennsylvania School of Medicine serendipitously found a novel cellular source of atrial fibrillation (AF), the most common type of abnormal heart beat. Jonathan Epstein, MD, William Wikoff Smith Professor, and Chair, Department of Cell and Developmental Biology, and Vickas Patel, MD, PhD, Assistant Professor of Medicine, have identified a population of cells in the atria of the heart and pulmonary veins of humans and mice that appear to be the seat of AF. The finding may lead to a more precise way to treat AF, with reduced side effects. Their findings appear online in the Journal of Clinical Investigation........ ]]> http://medicineworld.org/stories/lead/11-2009/handedness-may-effect-body-perception.html http://medicineworld.org/stories/lead/11-2009/handedness-may-effect-body-perception.html Fri, 06 Nov 2009 14:56:41 GMT There are areas in the brain devoted to our arms, legs, and various parts of our bodies. The way these areas are distributed throughout the brain are known as "body maps" and there are some significant differences in these maps between left- and right-handed people. For example, in left-handed people, there is an equal amount of brain area devoted to the left and right arms in both hemispheres. However, for right-handed people, there is more cortical area linked to right arm than the left........ ]]> http://medicineworld.org/stories/lead/11-2009/religion-and-medicine.html http://medicineworld.org/stories/lead/11-2009/religion-and-medicine.html Fri, 06 Nov 2009 14:56:41 GMT Do pediatric oncologists feel that religion is a bridge or a barrier to their work? Or do they feel it can be either, depending on whether their patients are recovering or deteriorating? A novel Brandeis University study examines these questions in the current issue of Social Problems Through in-depth interviews with 30 pediatricians and pediatric oncologists at elite medical centers, the authors discovered that physicians tend to view religion and spirituality pragmatically, considering them resources in family decision-making and in end of life situations, and barriers when they conflict with medical decisions, said main author Brandeis sociologist Wendy Cadge........ ]]> http://medicineworld.org/stories/lead/11-2009/acetaminophen-may-cause-asthma.html http://medicineworld.org/stories/lead/11-2009/acetaminophen-may-cause-asthma.html Fri, 06 Nov 2009 14:56:41 GMT New research shows that the widely used pain reliever acetaminophen appears to be linked to an increased risk of asthma and wheezing in both children and adults exposed to the drug. Scientists from the University of British Columbia, Vancouver, BC, Canada, conducted a systematic review and metaanalysis of 19 clinical studies (total subjects=425,140) that compared the risk of asthma or wheezing with acetaminophen exposure........ ]]> http://medicineworld.org/stories/lead/11-2009/benefit-from-oral-contraceptives.html http://medicineworld.org/stories/lead/11-2009/benefit-from-oral-contraceptives.html Fri, 06 Nov 2009 14:56:41 GMT New research shows that during natural menstrual cycles, women with asthma who were not taking oral contraceptives (OC) had lower exhaled nitric oxide levels (eNO), a marker of airway inflammation linked to asthma, than women who were taking OC. Scientists from McMaster University in Hamilton, ON, Canada, studied 17 women with asthma during their menstrual cycles. Results showed that individuals not using oral contraceptives (OC) had higher mean eNO levels than women using OC........ ]]> http://medicineworld.org/stories/lead/11-2009/green-tea-may-prevent-oral-cancer.html http://medicineworld.org/stories/lead/11-2009/green-tea-may-prevent-oral-cancer.html Fri, 06 Nov 2009 14:56:41 GMT Green tea extract has shown promise as cancer prevention agent for oral cancer in patients with a pre-cancerous condition known as oral leukoplakia, as per scientists at The University of Texas M. D. Anderson Cancer Center. The study, published online in Cancer Prevention Research, is the first to examine green tea as a chemopreventative agent in this high-risk patient population. The scientists observed that more than half of the oral leukoplakia patients who took the extract had a clinical response........ ]]> http://medicineworld.org/stories/lead/11-2009/weight-training-for-breast-cancer-survivors.html http://medicineworld.org/stories/lead/11-2009/weight-training-for-breast-cancer-survivors.html Fri, 06 Nov 2009 14:56:41 GMT In addition to building muscle, weightlifting is also a prescription for self-esteem among breast cancer survivors, as per new University of Pennsylvania School of Medicine research.

Will it grow quickly and aggressively and require continuous therapy, or slowly, allowing treatment and its risks to be safely delayed? The answer may lie in the size and shape of the blood vessels that are visible within the cancer, as per research led by researchers at The Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute in collaboration with the Harvard School of Public Health........ ]]> http://medicineworld.org/stories/lead/11-2009/colorful-fruits-and-vegetable.html http://medicineworld.org/stories/lead/11-2009/colorful-fruits-and-vegetable.html Fri, 06 Nov 2009 14:56:41 GMT Hoping to keep the flu at bay?
