In their article, Pamela Smith of Radboud University Nijmegen, and his colleagues Nils B. Jostmann of VU University Amsterdam, Adam Galinsky of the Kellogg School of Management at Northwestern University, and Wilco W. van Dijk of VU University Amsterdam, focus on a set of cognitive processes called executive functions. Executive functions help people maintain and pursue their goals in difficult, distracting situations. The scientists observed that lacking power impaired people's ability to keep track of ever-changing information, to parse out irrelevant information, and to successfully plan ahead to achieve their goals........ ]]> http://medicineworld.org/cancer/lead/5-2008/dr.-anthony-fauci-reflects-on-25-years-of-hiv.html http://medicineworld.org/cancer/lead/5-2008/dr.-anthony-fauci-reflects-on-25-years-of-hiv.html Fri, 16 May 2008 02:33:15 GMT On the 25th anniversary of the first scientific article linking a retrovirus to AIDS, Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, reflects in an essay in Nature on his experience treating and studying HIV/AIDS for the past quarter century. Outlining the peaks and valleys of the scientific communitys journey so far, Dr. Fauci writes, we must learn from our mis-steps, build on our successes in therapy and prevention, and renew our commitment to developing the truly transforming tools that will one day put this scourge behind us........ ]]> http://medicineworld.org/cancer/lead/5-2008/visual-system-equipped-with-future.html http://medicineworld.org/cancer/lead/5-2008/visual-system-equipped-with-future.html Fri, 16 May 2008 02:33:15 GMT Catching a football. Maneuvering through a room full of people. Jumping out of the way when a golfer yells "fore." Most would agree these seemingly simple actions require us to perceive and quickly respond to a situation. Assistant Professor of Cognitive Science at Rensselaer Polytechnic Institute Mark Changizi argues they require something more - our ability to foresee the future........ ]]> http://medicineworld.org/cancer/lead/5-2008/doubt-on-risk-of-death-from-higher-salt-intake.html http://medicineworld.org/cancer/lead/5-2008/doubt-on-risk-of-death-from-higher-salt-intake.html Fri, 16 May 2008 02:33:15 GMT Contrary to long-held assumptions, high-salt diets may not increase the risk of death, as per researchers from the Albert Einstein College of Medicine of Yeshiva University. They reached their conclusion after examining dietary intake among a nationally representative sample of adults in the U.S. The Einstein scientists actually observed a significantly increased risk of death from cardiovascular disease (CVD) linked to lower sodium diets. They report their findings in the advance online edition of the Journal of General Internal Medicine........ ]]> http://medicineworld.org/cancer/lead/5-2008/link-between-vitamin-d-status-breast-cancer.html http://medicineworld.org/cancer/lead/5-2008/link-between-vitamin-d-status-breast-cancer.html Fri, 16 May 2008 02:33:15 GMT Using newly available data on worldwide cancer incidence, scientists at the Moores Cancer Center at University of California, San Diego (UCSD) and the Department of Family and Preventive Medicine have shown a clear association between deficiency in exposure to sunlight, specifically ultraviolet B (UVB), and breast cancer........ ]]> http://medicineworld.org/cancer/lead/5-2008/risk-for-developing-breast-cancer.html http://medicineworld.org/cancer/lead/5-2008/risk-for-developing-breast-cancer.html Fri, 16 May 2008 02:33:15 GMT A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help scientists more accurately determine a woman's risk for developing breast cancer and provide a new approach for therapy, UT Southwestern Medical Center scientists have found. As per a research findings published in today's issue of Cancer Epidemiology Biomarkers and Prevention, researchers from UT Southwestern show that the chemical process, called methylation, is strongly correlated with breast-cancer risk and with premalignant changes in the breast cells........ ]]> http://medicineworld.org/cancer/lead/5-2008/teens-reach-linguistic-peak-in-online-chat.html http://medicineworld.org/cancer/lead/5-2008/teens-reach-linguistic-peak-in-online-chat.html Fri, 16 May 2008 02:33:15 GMT Parents and teachers worry that teenagers use of these and other forms of online shorthand is harming their language skills. Perhaps they will take comfort from a study suggesting that instant messaging (IM) actually represents an expansive new linguistic renaissance. Sali Tagliamonte and Derek Denis at the University of Toronto, Canada, say teenagers risk the disapproval of their elders if they use slang, and the scorn of their friends if they sound too buttoned-up. But instant messaging allows them to deploy a robust mix of colloquial and formal language. In a paper would be reported in the spring 2008 issue of American Speech, the scientists argue that far from ruining teenagers ability to communicate, IM lets teenagers show off what they can do with language........ ]]> http://medicineworld.org/cancer/lead/5-2008/middle-class-relaxing-with-marijuana.html http://medicineworld.org/cancer/lead/5-2008/middle-class-relaxing-with-marijuana.html Fri, 16 May 2008 02:33:15 GMT A variety of middle-class people are making a conscious but careful choice to use marijuana to enhance their leisure activities, a University of Alberta study shows. A qualitative study of 41 Canadians surveyed in 2005-06 by U of A scientists showed that there is no such thing as a typical marijuana user, but that people of all ages are selectively lighting up the drug as a way to enhance activities ranging from watching television and playing sports to having sex, painting or writing........ ]]> http://medicineworld.org/cancer/lead/5-2008/attitudes-to-stem-cell-research.html http://medicineworld.org/cancer/lead/5-2008/attitudes-to-stem-cell-research.html Fri, 16 May 2008 02:33:15 GMT Unlike most scientific and technological advances, which tend to take their place silently in society, biotechnology often finds itself the center of public debate and regulatory attention, due partly to the moral issues posed by a number of of its applications. In this second BBVA Foundation international study on Attitudes to Biotechnology (the first was in 2003), the sample has been enlarged from nine to twelve European countries (Austria, Czech Republic, Gera number of, Denmark, Spain, France, Ireland, Italy, Netherlands, Poland, United Kingdom and Sweden), with the addition of countries from other continents; namely the United States, Japan and Israel. The selection of countries was informed by both their demographical weight and their variability from the standpoint of religious beliefs and cultural traditions........ ]]> http://medicineworld.org/cancer/lead/5-2008/mothers-depression-young-childrens-injuries.html http://medicineworld.org/cancer/lead/5-2008/mothers-depression-young-childrens-injuries.html Fri, 16 May 2008 02:33:15 GMT Infants and toddlers whose mothers are severely depressed are almost three times more likely to suffer accidental injuries than other children in the same age group, as per a new study. The study's findings, published recently in the Advanced Access edition of the Journal of Pediatric Psychology, suggest that proper therapy for depression would improve not only the mothers' health, but the health of young children as well........ ]]> http://medicineworld.org/cancer/lead/5-2008/alzheimers-like-brain-tangles.html http://medicineworld.org/cancer/lead/5-2008/alzheimers-like-brain-tangles.html Fri, 16 May 2008 02:33:15 GMT Scientists at the Yerkes National Primate Research Center, Emory University, have discovered the first conclusive evidence of Alzheimer's-like neurofibrillary brain tangles in an aged nonhuman primate. The unprecedented finding, described in the online issue of the Journal of Comparative Neurology, has the potential to move the scientific community one step closer to understanding why age-related neurodegenerative diseases, such as Alzheimer's disease, are uniquely human and seem to never fully manifest in other species--including our closest evolutionary relative, the chimpanzee........ ]]> http://medicineworld.org/cancer/lead/5-2008/adding-ultrasound-screening-to-mammography.html http://medicineworld.org/cancer/lead/5-2008/adding-ultrasound-screening-to-mammography.html Fri, 16 May 2008 02:33:15 GMT Adding a screening ultrasound examination to routine mammography reveals more breast cancers than mammography alone, as per results of a major new clinical trial. The trial, however, also observed that adding an ultrasound exam also increases the rate of false positive findings and unnecessary biopsies........ ]]> http://medicineworld.org/cancer/lead/5-2008/high-blood-pressure-and-high-cholesterol.html http://medicineworld.org/cancer/lead/5-2008/high-blood-pressure-and-high-cholesterol.html Fri, 16 May 2008 02:33:15 GMT Hypertension and high cholesterol levels appear to be risk factors for retinal vein occlusion, a condition that causes vision loss, as per a report in the recent issue of Archives of Ophthalmology, one of the JAMA/Archives journals. Retinal vein occlusion occurs when one or more veins carrying blood from the eye to the heart become blocked, as per background information in the article. Bleeding (hemorrhage) or fluid buildup (edema) may follow, damaging vision........ ]]> http://medicineworld.org/cancer/lead/5-2008/vision-therapy-visual-function.html http://medicineworld.org/cancer/lead/5-2008/vision-therapy-visual-function.html Fri, 16 May 2008 02:33:15 GMT A low-vision treatment program that includes a home visit, counseling, assistive devices such as magnifiers and assignments to practice using them appears to significantly improve vision in veterans with diseases of the macula (the area of the retina with the sharpest vision), as per a report in the recent issue of Archives of Ophthalmology, one of the JAMA/Archives journals........ ]]> http://medicineworld.org/cancer/lead/5-2008/when-schools-ban-unhealthy-snacks.html http://medicineworld.org/cancer/lead/5-2008/when-schools-ban-unhealthy-snacks.html Fri, 16 May 2008 02:33:15 GMT Children who attend schools that run fruit tuck shops are much more likely to eat more fruit if they and their friends are also banned from bringing unhealthy snacks on to the school premises, as per research published online ahead of print in the Journal of Epidemiology and Community Health. Scientists at Cardiff University studied the snacking habits of 9-11 year olds attending 43 primary schools in deprived areas of South Wales and South West England which had a variety of policies on bringing food to school: no restrictions, fruit only or no food at all........ ]]>
