No Link Found Between Viral Infection And Rapidly Developing Type 1 Diabetes In Young Children
Date: May-08-2013Some of the earliest results from The Environmental Determinants of Diabetes in The Young (TEDDY) study - a major Europe-USA consortium exploring the causes of type 1 diabetes in children - has found no evidence for viral infection as a cause of the rapid-onset form of the condition...
New Study Reveals Important Mechanism For Tumorigenesis
Date: May-08-2013Cancer is a complex disease, in which cells undergo a series of alterations, including changes in their architecture; an increase in their ability to divide, to survive and to invade new tissues or metastasis. A category of genes, called oncogenes, is critical during cancer progression, as they codify proteins whose activity favours the development of cancer. One of these molecules, Src, is implicated in a large number of human cancers. However, it is still not clear how healthy cells constrain its activity not to become tumorous...
Link Between Weight Gain And Personality Trait Changes
Date: May-08-2013People who gain weight are more likely to give in to temptations but also are more thoughtful about their actions, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. To understand how fluctuations in body weight might relate to personality changes, psychological scientist Angelina Sutin of the Florida State University College of Medicine and colleagues at the National Institutes of Health (NIH) examined data from two large-scale longitudinal studies of Baltimore residents...
Some Seniors Could Be Driven Out Of Medicare Program By Attempts To Curb Costs
Date: May-08-2013The rising cost of Medicare can be cut through strategies such as increasing premiums and raising the eligibility age, but those moves could drive many elderly Americans from the program, leaving them with limited access to health services, according to a new study. Researchers simulated the likely outcomes of three approaches for lowering Medicare costs -- imposing a premium for Medicare's hospital insurance, switching to a premium support program that subsidizes the cost of purchasing private coverage, and increasing the eligibility age to 67...
Those With Older Or Younger Spouses Tend To Have Lower Earnings, Less Education
Date: May-08-2013Despite the popular image of the rich older man or woman supporting an attractive younger spouse, a new study shows those married to younger or older mates have on average lower earnings, lower cognitive abilities, are less educated and less attractive than couples of similar ages. "Hugh Hefner is an outlier," said Hani Mansour, Ph.D., an assistant professor of economics at the University of Colorado Denver who co-authored the study with Terra McKinnish, Ph.D., associate professor of economics at the University of Colorado Boulder...
Study Of Stress On Brain Cells Offers Clues To New Anti-Depressant Drugs
Date: May-08-2013Research from King's College London reveals the detailed mechanism behind how stress hormones reduce the number of new brain cells - a process considered to be linked to depression. The researchers identified a key protein responsible for the long-term detrimental effect of stress on cells, and importantly, successfully used a drug compound to block this effect, offering a potential new avenue for drug discovery...
Wip1 Could Be New Target For Treatment Of Colorectal, Breast And Ovarian Cancers
Date: May-08-2013Researchers have uncovered mutations in the phosphatase Wip1 that enable cancer cells to foil the tumor suppressor p53, according to a study in The Journal of Cell Biology. The results could provide a new target for the treatment of certain cancers. Like a battlefield surgeon who has to decide which casualties can be saved, p53 performs triage on cells with injured DNA. If the damage is serious, p53 spurs the cells to die or stop proliferating...
Global Burden Of Hepatitis C Could Be Significantly Reduced By New Antiviral Treatment
Date: May-08-2013Around 150 million people globally are chronically infected with the hepatitis C virus (HCV) - a major cause of liver disease and the fastest growing cause of liver transplantation and liver cancer. 1 New prevention strategies are urgently required as people are continuing to be infected with HCV. Findings, published in Hepatology, reveal the impact of a new antiviral treatment that could potentially reduce HCV rates in some cities affected by chronic HCV prevalence by half over 15 years...
Delaying The Aging Process By Boosting 'Cellular Garbage Disposal'
Date: May-08-2013UCLA life scientists have identified a gene previously implicated in Parkinson's disease that can delay the onset of aging and extend the healthy life span of fruit flies. The research, they say, could have important implications for aging and disease in humans. The gene, called parkin, serves at least two vital functions: It marks damaged proteins so that cells can discard them before they become toxic, and it is believed to play a key role in the removal of damaged mitochondria from cells...
Health Status Surveys Can Improve A Heart Patients' Quality Of Life
Date: May-08-2013Completing a quality-of-life questionnaire at a healthcare provider's office could help patients live longer and live better, according to a new scientific statement published in Circulation, a journal of the American Heart Association. In the statement, the association urges healthcare providers to assess their patients' cardiovascular health by using standardized patient surveys. These surveys directly measure the impact of heart disease on patients, including their symptoms, quality of life, and ability to function physically and mentally...
