UK Food Advertising Regulations Have Done Little To Address Exposure Of Children To Unhealthy Food Marketing
Date: May-17-2013Regulations brought in by the UK to reduce the volume of television advertising of unhealthy foods to children appear to have little impact on the advertising around programmes children actually watch, according to research presented at the European Congress on Obesity in Liverpool, UK. The research is by Dr Emma Boyland and Professor Jason Halford, University of Liverpool, UK, and colleagues. The authors did an analysis of food advertising on television in the UK in 2008 (when some regulation was in place) compared to 2010 (when new regulations had fully taken effect)...
The Story Of Fat Alfie: Very Young Children Appear To Reject Story Characters Who Are Obese
Date: May-17-2013New research presented as the European Congress on Obesity (ECO) in Liverpool, UK, shows that very young children appear to reject story book characters who are overweight, but not those who are disabled. The research is by Professor Andrew Hill, Dr Sarah Harrison, and Dr Maddie Rowlinson, University of Leeds, UK. Previous research has suggested that, far from improving over time, the attitudes and perceptions of children to obesity may have deteriorated since the 1960s...
Malaria Parasites 'Talk' To Each Other
Date: May-17-2013Melbourne scientists have made the surprise discovery that malaria parasites can 'talk' to each other - a social behaviour to ensure the parasite's survival and improve its chances of being transmitted to other humans. The finding could provide a niche for developing antimalarial drugs and vaccines that prevent or treat the disease by cutting these communication networks...
Consuming Less Sugar-Sweetened Beverages May Reduce Kidney Stone Risk
Date: May-17-2013Twenty percent of American males and 10 percent of American females will experience a kidney stone at some point in their lifetime. Often, these patients will be advised to drink more fluids as a way to prevent future stone formation. Now, new research from Brigham and Women's Hospital finds that some beverages may be more helpful than others when it comes to preventing recurrent kidney stones...
Breakthrough Marks The First Time Human Stem Cells Have Been Produced Via Nuclear Transfer
Date: May-17-2013Scientists at Oregon Health & Science University and the Oregon National Primate Research Center (ONPRC) have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any other cell type in the body. It is believed that stem cell therapies hold the promise of replacing cells damaged through injury or illness. Diseases or conditions that might be treated through stem cell therapy include Parkinson's disease, multiple sclerosis, cardiac disease and spinal cord injuries. The research breakthrough, led by Shoukhrat Mitalipov, Ph.D...
MRI Useful For Predicting Failure Of Metal-On-Metal Hip Implants Before Symptoms Appear
Date: May-17-2013Metal-on-metal hip implants can cause inflammation of the joint lining (synovitis) long before symptoms appear, and magnetic resonance imaging (MRI) can be used to identify this inflammation, according to a new study by researchers at Hospital for Special Surgery. The study, which appears in an upcoming issue of the Journal of Bone & Joint Surgery, demonstrates that MRI can be used to identify implants that are going to fail before people become symptomatic. "The study shows that synovitis exists in asymptomatic people in a fairly high prevalence," said Hollis Potter, M.D...
Tuberculosis Pathogen Proteome Atlas
Date: May-17-2013Photographers know the problem all too well: with the naked eye, you can see which branch a bird is sitting on, but spotting the bird in the blur of branches through the telephoto lens for high-magnification images requires considerable skill. It is a similar story for researchers who are looking to study proteins, the active biomolecules of cells. Olga Schubert, a doctoral student at ETH Zurich's Institute for Molecular Systems Biology, and her colleagues have now come up with a search aid...
Experts Challenge Assumption, Describe Pathway That Leads To Organ Rejection
Date: May-17-2013Transplant researchers at the University of Pittsburgh School of Medicine challenge a long-held assumption about how biologic pathways trigger immune system rejection of donor organs in a report published online today in the Journal of Clinical Investigation. Their study, sponsored by the National Institutes of Health, suggests a different paradigm is needed to develop better anti-rejection therapies. Immune system troops called T-cells migrate to transplanted organs, fighting the foreign tissue, explained senior author Fadi Lakkis, M.D...
Infection And Sepsis-Related Mortality Hotspots Identified Across The US
Date: May-17-2013In the past, researchers have sought to determine the geographic distribution of many life-threatening conditions, including stroke and cardiac arrest. Now, researchers at the Perelman School of Medicine at the University of Pennsylvania have created the first U.S. map that pinpoints hotspots for infection and severe sepsis related-deaths - with notable clusters located in the Midwest, mid-Atlantic, and the South. The research is a critical first step in helping to determine which areas of the country require vital public health resources to fight these deadly diseases...
Depressed Patients Have As Many Goals As Healthy People, But Describe Them In Vague Terms
Date: May-17-2013People suffering from clinical depression express personal goals and reasons for their attainment or failure in less specific terms than people without the disorder. This lack of specificity in representing personal goals may be partially responsible for the motivational deficits seen in these patients, according to research published in the open access journal PLOS ONE by Joanne Dickson from the University of Liverpool, UK and Nicholas Moberly from the University of Exeter, UK...
