Identification Of Area In The Brain Responsible For Numeral Recognition
Date: Apr-18-2013Scientists at the Stanford University School of Medicine have determined the precise anatomical coordinates of a brain "hot spot," measuring only about one-fifth of an inch across, that is preferentially activated when people view the ordinary numerals we learn early on in elementary school, like "6" or "38." Activity in this spot relative to neighboring sites drops off substantially when people are presented with numbers that are spelled out ("one" instead of "1"), homophones ("won" instead of "1") or "false fonts," in which a numeral or letter has been altered...
Microneedle Adhesive More Than 3x Stronger Than Surgical Staples In Skin Graft Fixation
Date: Apr-18-2013A parasitic worm may hold the answer to keeping skin grafts firmly in place over wounds, according to a new study by researchers at Brigham and Women's Hospital (BWH). The study was published in the journal Nature Communications. The research team, led by Jeffrey Karp, PhD, BWH Division of Biomedical Engineering, Department of Medicine, senior study author, invented a microneedle inspired by Pomphorhynchus laevis, a spiny-headed worm that lives in the intestines of its hosts, in this case fish...
UK's Low Bowel Cancer Survival Likely Due To Differences In Staging And Treatment
Date: Apr-18-2013Incomplete diagnostic investigation and failure to get the best treatment are the most likely reasons why survival for bowel cancer patients is lower in the UK than in other comparable countries, according to new research published in the journal Acta Oncologica. The research, led by the London School of Hygiene & Tropical Medicine, was carried out in Australia, Canada, Denmark, Norway, Sweden and the UK for the International Cancer Benchmarking Partnership (ICBP). The study included more than 310,000 bowel cancer patients diagnosed during 2000-07...
Long-Term Cancer Survivors May Be At Increased Risk For Heart Disease
Date: Apr-18-2013Many people survive their cancers, but end up dying of cardiovascular disease (CVD). New research from Wake Forest Baptist Medical Center finds that CVD risk factors may be overlooked during survivorship care. Kathryn E. Weaver, Ph.D., assistant professor of social sciences and health policy at Wake Forest Baptist, and colleagues surveyed survivors of breast, prostate, colorectal and gynecologic cancers in search of answers...
Improving The Antitumor Activity Of Interferon
Date: Apr-18-2013Interferons have antitumor activity and have been used to treat a variety of malignancies, including colorectal and ovarian cancers. However, their effectiveness varies. A clearer understanding of the role of interferon in immune-mediated tumor cell death and how its antitumor effects could be optimized are presented in a comprehensive Review article published in Journal of Interferon & Cytokine Research, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free online on the Journal of Interferon & Cytokine Research website...
Exploring The Science Behind Medical Acupuncture
Date: Apr-18-2013Even as medical acupuncture is increasingly being validated as an effective treatment for a broad range of medical conditions, what has been missing is an understanding of the basic science and mechanisms of action of this age-old method of healing. A special issue of Medical Acupuncture, a peer-reviewed journal published by Mary Ann Liebert, Inc., publishers presents a series of articles by authors from around the world who provide diverse and insightful perspectives on the science and physiologic responses underlying medical acupuncture...
Infection Risks In Hospital Wards May Increase With Energy Efficiency
Date: Apr-18-2013The chance of infection in some hospital wards varies dramatically according to whether the nurses leave the windows open. A University of Leeds-led team studied airflow in a "Nightingale" ward - a classic hospital ward design that traditionally accommodates two rows of up to 30 beds - by using tracer gases to simulate how airborne infections spread. They found ventilation in the ward was generally good when windows were left open, keeping the danger of airborne infection low. But risks increased fourfold when the windows were closed...
Parent-Based Interventions Could Be Key To Helping Teens Resist Alcohol Experimentation During Transition From High School To College
Date: Apr-18-2013Prior research has shown that the transition from high school to college is a particularly vulnerable time, associated with increased alcohol use and risk of negative alcohol-related consequences. While studies have examined the effectiveness of prevention programs to address this problem, few have examined which students may benefit the most. A study of student characteristics has found that parent-based interventions (PBIs) can be effective even among those students feeling high peer pressure to drink alcohol...
Pregnant Women With High Blood Pressure May Be At Increased Risk For Cardiovascular Disease
Date: Apr-18-2013Women with high blood pressure during pregnancy have an increased risk of high blood pressure even 40 years after maternity, which leads in turn to an increased risk of cardiovascular disease. This has been demonstrated by researchers at Sahlgrenska Academy, University of Gothenburg, Sweden. In a recent study, researchers at Sahlgrenska Academy, University of Gothenburg examined 105 women who gave birth in the early 1970s. Half the women had elevated blood pressure during pregnancy, while the other half had a normal pregnancy...
Reducing The Pain Of Movement In Intensive Care
Date: Apr-18-2013Monitoring pain and providing analgesics to patients in intensive care units (ICUs) during non-surgical procedures, such as turning and washing, can not only reduce the amount of pain but also reduce the number of serious adverse events including cardiac arrest, finds new research in BioMed Central's open access journal Critical Care. Although pain at rest is routinely noted, pain during procedures is less regularly reported and its effect on patients unknown...
