Review Focuses On Nutritional Factors That Help Preserve Muscle Mass, Strength And Performance In Seniors
Date: Jan-22-2013New review by International Osteoporosis Foundation (IOF) Nutrition Working Group examines role of nutrition in sarcopenia, with focus on protein, vitamins D and B, and acid-based diet. Sarcopenia, or the gradual loss of muscle mass, is a common consequence of ageing, and poses a significant risk factor for disability in older adults. As muscle strength plays an important role in the tendency to fall, sarcopenia leads to an increased risk of fractures and other injuries...
Protein Folding Via Charge Zippers
Date: Jan-22-2013Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane. In the Cell magazine, researchers of Karlsruhe Institute of Technology and the University of Cagliari are now reporting a novel charge zipper principle used by proteins to form functional units (DOI: 10.1016/j.cell.2012.12.017)...
Computerized Tool And Simple Blood Test Can Help Identify Trauma Patients At Greatest Risk Of Death
Date: Jan-22-2013A study of more than 9,500 patients discovered that some trauma patients are up to 58 times more likely to die than others, regardless of the severity of their original injuries. The Intermountain Medical Center research study of more than 9,500 patients discovered that some trauma patients are up to 58 times more likely to die than others, regardless of the severity of their original injuries. Researchers say the study findings provide important insight into the long-term prognosis of trauma patients, something not previously well understood...
The Midwest Likely To Be Profoundly Affected By Climate Change In Coming Decades - A Threat To Public Health
Date: Jan-22-2013In the coming decades, climate change will lead to more frequent and more intense Midwest heat waves while degrading air and water quality and threatening public health. Intense rainstorms and floods will become more common, and existing risks to the Great Lakes will be exacerbated...
Veterinary Study Points To Promising New Target For Parkinson's Disease Therapies
Date: Jan-22-2013With a new insight into a model of Parkinson's disease, researchers from the University of Pennsylvania School of Veterinary Medicine have identified a novel target for mitigating some of the disease's toll on the brain. Narayan G. Avadhani, Harriet Ellison Woodward Professor of Biochemistry and chair of the Department of Animal Biology at Penn Vet, was the senior author on the research. Other department members contributing to the work included Prachi Bajpai, Michelle C. Sangar, Shilpee Singh, Weigang Tang, Seema Bansal and Ji-Kang Fang...
The Immune System Taxed By Loneliness, Similar To The Effect Of Chronic Stress
Date: Jan-22-2013New research links loneliness to a number of dysfunctional immune responses, suggesting that being lonely has the potential to harm overall health. Researchers found that people who were more lonely showed signs of elevated latent herpes virus reactivation and produced more inflammation-related proteins in response to acute stress than did people who felt more socially connected...
Discovery Of Surprising Connections Between Our Well-Being And Giving, Getting, And Gratitude
Date: Jan-22-2013We all know that getting a good night's sleep is good for our general health and well-being. But new research is highlighting a more surprising benefit of good sleep: more feelings of gratitude for relationships. "A plethora of research highlights the importance of getting a good night's sleep for physical and psychological well-being, yet in our society, people still seem to take pride in needing, and getting, little sleep," says Amie Gordon of the University of California, Berkeley...
Mapping Our Online Communications - From Bullying To Relationships
Date: Jan-22-2013When we typically think of kids who are the victims of school bullying, what comes to mind are isolated youth who do not fit in. A new study, however, shows that when that harassment occurs online, the victims tend to be in mainstream social groups at the school - and they are often friends or former friends, not strangers. The research is part of a burgeoning field of study into the effects of social media on everyday relationships and behavior...
Promoting Health And Physical Activity Via Carefully Worded Text Messages To Teenagers
Date: Jan-22-2013Teenagers spend a lot of time texting, receiving an average of 3,417 texts a month, or 114 per day, according to the Nielsen consumer research group. A new study from the University of Arizona looks at the feasibility of using text messaging to deliver educational information about nutrition and physical activity to teens. The study, which appears in the January-February issue of the Journal of Nutrition Education and Behavior, looks at whether teenagers would be interested in receiving texts about health on their phones and how they would like those messages presented...
Advanced Practice Nurses And Physician Assistants Can Safely Perform Abortions
Date: Jan-22-2013First trimester abortions are just as safe when performed by trained nurse practitioners, physician assistants and certified nurse midwives as when conducted by physicians, according to a new six-year study led by UCSF. The study posted online in the American Journal of Public Health in advance of the print edition. The publication comes a week before the 40th anniversary of the Roe vs. Wade, the landmark Supreme Court decision that made abortion legal in the United States...
