Bacteria Breakthrough For Safer Food
Date: Jan-16-2013Chicken meat and other foods will be able to be screened for bacteria even faster and more effectively than ever, thanks to breakthrough nanobiotechnology research. A team of scientists from The University of Queensland (UQ) and the Department of Agriculture, Fisheries and Forestry (DAFF) will leverage this new technology which enables DNA amplification on "microspheres" to rapidly detect and identify large numbers of different bacteria at once...
In Seniors Over 75, Diet May Not Impact Certain Health Outcomes
Date: Jan-16-2013Eating diets high in sugar and fat may not affect the health outcomes of older adults ages 75 and up, suggesting that placing people of such advanced age on overly restrictive diets to treat their excess weight or other conditions may have little benefit, according to researchers at Penn State and Geisinger Healthcare System. "Historically people thought of older persons as tiny and frail," said Gordon Jensen, head of the Department of Nutritional Sciences at Penn State, "but that paradigm has changed for many older persons...
Early Childhood Environment May Explain Why People Spend Or Save
Date: Jan-16-2013In the face of hard times, which strategy gives us the best shot at survival: saving for the future or spending resources on immediate gains? The answer may depend on the economic conditions we faced in childhood, according to new research published in Psychological Science, a journal of the Association for Psychological Science...
Software Reveals New Clues To Degenerative Diseases
Date: Jan-16-2013An effort to develop software that unravels the complexities of how proteins fold is paying dividends in new findings on how they misfold, according to researchers at Rice University. The study published this week in the Proceedings of the National Academy of Sciences by chemist Peter Wolynes and his team at Rice's BioScience Research Collaborative should be of particular interest to those who probe the roots of degenerative diseases associated with the aggregation of amyloid fibers in the body. These include Alzheimer's and Parkinson's diseases and Type 2 diabetes...
Scientists Discover Structure Of Protein Essential For Quality Control, Nerve Function
Date: Jan-16-2013Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered "quality-control" protein that is found in the cells of all plants, fungi and animals. Ltn1 appears to be essential for keeping cells' protein-making machinery working smoothly. It may also be relevant to human neurodegenerative diseases, for an Ltn1 mutation in mice leads to a motor-neuron disease resembling amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease)...
Vitamin D Levels In Children Most Likely Determined By Supplements Taken And Consumption Of Cow's Milk
Date: Jan-16-2013Taking a vitamin D supplement and drinking cow's milk are the two most important factors that determine how much vitamin D is in a child's body, new research has found. Those factors play a bigger role than even skin colour and exposure to the sun, according to Dr. Jonathon Maguire, a researcher and pediatrician at St. Michael's Hospital. "Early childhood is a critical stage in human development, so achieving and maintaining optimal vitamin D levels in early childhood may be important to health outcomes in later childhood and adulthood," Dr. Maguire said...
Seeking Treatments To Reverse Physical Changes In The Brain Caused By Childhood Trauma
Date: Jan-16-2013It is well known that violent adults often have a history of childhood psychological trauma. Some of these individuals exhibit very real, physical alterations in a part of the brain called the orbitofrontal cortex. Yet a direct link between such early trauma and neurological changes has been difficult to find, until now. Publishing in the January 15 edition of Translational Psychiatry, EPFL Professor Carmen Sandi and team demonstrate for the first time a correlation between psychological trauma in pre-adolescent rats and neurological changes similar to those found in violent humans...
Protective Role Identified For Antibodies In Ebola Vaccine Study
Date: Jan-16-2013Researchers at the National Institutes of Health (NIH) and Oregon Health & Science University (OHSU) have found that an experimental vaccine elicits antibodies that can protect nonhuman primates from Ebola virus infection. Ebola virus causes severe hemorrhagic fever in humans and nonhuman primates, meaning that infection may lead to shock, bleeding and multi-organ failure. According to the World Health Organization, Ebola hemorrhagic fever has a fatality rate of up to 90 percent. There is no licensed treatment or vaccine for Ebola virus infection...
Women Who Regularly Consume Strawberries And Blueberries May Reduce Their Risk For Heart Attack
Date: Jan-16-2013Eating three or more servings of blueberries and strawberries per week may help women reduce their risk of a heart attack by as much as one-third, researchers reported in Circulation: Journal of the American Heart Association. Blueberries and strawberries contain high levels of naturally occurring compounds called dietary flavonoids, also found in grapes and wine, blackberries, eggplant, and other fruits and vegetables...
Gene Discovered That Promotes Drug Resistance In Cancer
Date: Jan-16-2013Increased NEK2 gene expression linked to increased drug resistance, faster cancer growth, and poorer patient outcom. The finding may improve diagnostic and prognostic tools for cancer care and could lead to improved cancer therapies. Scientists from the University of Iowa and Brigham Young University (BYU) have identified a gene that may be a target for overcoming drug resistance in cancer...
