Digestive Enzymes May Be Responsible For Shock, Multiorgan Failure
Date: Jan-25-2013New research from the University of California, San Diego published in the journal Science Translational Medicine moves researchers closer to understanding and developing treatments for shock, sepsis and multiorgan failure. Collectively, these maladies represent a major unmet medical need: they are the number one cause of mortality in intensive care units in the United States, with hundreds of thousands of deaths annually. There is currently no treatment for these conditions in spite of many clinical trials...
High-Calorie Foods Sought During Difficult Times
Date: Jan-25-2013Bad news about the economy could cause you to pack on the pounds, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. The study shows that when there is a perception of tough times, people tend to seek higher-calorie foods that will keep them satisfied longer. When subconsciously primed with such messages, a "live for today" impulse is triggered causing people to consume nearly 40 percent more food than when compared to a control group primed with neutral words...
Carcinogenic Fumes From Chinese E-Waste Site Increase Lung Cancer Risk In Local Residents
Date: Jan-25-2013Residents living near an e-waste recycling site in China face elevated risks of lung cancer, according to a recent study co-authored by Oregon State University researchers. Electronic trash, such as cell phones, computers and TVs, is often collected in dumps in developing countries and crudely incinerated to recover precious metals, including silver, gold, palladium and copper. The process is often primitive, releasing fumes with a range of toxic substances, including polycyclic aromatic hydrocarbons, or PAHs, a group of more than 100 chemicals...
Increased Fruit And Veg Consumption Associated With Positive Mood
Date: Jan-25-2013Eating more fruit and vegetables may make young people calmer, happier and more energetic in their daily life, new research from New Zealand's University of Otago suggests. Department of Psychology researchers Dr Tamlin Conner and Bonnie White, and Dr Caroline Horwath from Otago's Department of Human Nutrition, investigated the relationship between day-to-day emotions and food consumption. The study is published in the British Journal of Health Psychology. A total of 281 young adults (with a mean age of 20 years) completed an internet-based daily food diary for 21 consecutive days...
Promising Prognostic Marker Discovered For Aggressive Breast Cancer
Date: Jan-25-2013A team of researchers led by Goutham Narla, MD, PhD, at Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, and collaborators at the Mount Sinai School of Medicine and Erasmus Medical Center, have discovered a gene variant that drives the spread of breast cancer. Published in Science Translational Medicine, the study lays the early foundation for predicting which breast cancer patients may develop more aggressive disease and for designing more effective treatments...
Recessive Mutations In Middle Eastern Families Shed Light On Some US Cases Of Autism
Date: Jan-25-2013While autism clearly runs in some families, few inherited genetic causes have been found. A major reason is that these causes are so varied that it's hard to find enough people with a given mutation to establish a clear pattern. Researchers at Boston Children's Hospital have pinpointed several inherited mutations - among the first to be identified - through an unusual approach: using whole-exome sequencing to study large Middle Eastern families with autism. The study, published in the journal Neuron, also found evidence for some of the same mutations in U.S. families...
Successful Mental Health Approach To Teenage Alcohol Prevention
Date: Jan-25-2013Targeted psychological interventions aimed at teenagers at risk of emotional and behavioural problems significantly reduce their drinking behaviour, and that of their schoolmates, according to the results from a large randomised controlled trial published in JAMA Psychiatry. The authors argue that the intervention could be administered in schools throughout the UK to help prevent teenage alcohol abuse...
Natural Switch Discovered That Controls Spread Of Breast Cancer Cells
Date: Jan-25-2013With a desire to inhibit metastasis, Cornell biomedical engineers have found the natural switch between the body's inflammatory response and how malignant breast cancer cells use the bloodstream to spread.* Pro-inflammatory signaling molecules in blood called cytokines constitute a "switch" that induces the mechanism by which breast cancer cells "roll" and adhere to the blood vessel surface. The cancer cells eventually stick to the vessel and infiltrate it. The laboratory of Michael R...
New Method Predicts Brain Cancer Outcome And Quickly Shows If Therapy Is Effective
Date: Jan-25-2013The critical question shortly after a brain cancer patient starts treatment: how well is it working? But there hasn't been a good way to gauge that. Now Northwestern Medicine researchers have developed a new method -- similar to forecasting storms with computer models -- to predict an individual patient's brain tumor growth. This growth forecast will enable physicians to rapidly identify how well the tumor is responding to a particular therapy. The approach allows a quick pivot to a new therapy in a critical time window if the current one isn't effective...
New Norovirus Strain Behind Recent Outbreaks In U.S.
Date: Jan-25-2013A new norovirus strain, known as GII.4 Sydney, has been identified as the main cause of norovirus outbreaks in the U.S. from September to December 2012. The finding came from the Morbidity and Mortality Weekly Report released this week by the CDC (Centers for Disease Control and Prevention). The new strain was first detected in Australia in march of last year, resulting in several outbreaks in that county, as well as many other nations. A team of CDC experts gathered and examined data through CaliciNet on norovirus strains linked to outbreaks in 2012 in the U.S...
