Stress early in life leads to adulthood anxiety and preference for "comfort foods"
Date: Aug-02-2013New research finds that adult rats reared in a stressful neonatal environment demonstrate more anxiety and stress, and they prefer to eat more foods rich in fat and sugar. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that exposure to stress in the first few days of life increases stress responses, anxiety and the consumption of palatable "comfort" foods in adulthood...
Offspring of mothers stressed during pregnancy with a passive stress coping style more prone to Obesity
Date: Aug-02-2013New animal research suggests greater risk for obesity and associated type 2 diabetes in individuals that respond to stress in a passive manner and were born to mothers that were stressed during their pregnancy. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, shows that passively coping offspring of mothers stressed during their pregnancy were at risk to develop obesity and type 2 diabetes...
Understanding the effects of genes on human traits
Date: Aug-02-2013Recent technological developments in genomics have revealed a large number of genetic influences on common complex diseases, such as diabetes, asthma, cancer or schizophrenia. However, discovering a genetic variant predisposing to a disease is only a first step. To apply this knowledge towards prevention or cure, including tailoring treatment to the patient's genetic profile - also known as personalized medicine - we need to know how this genetic variant affects health. In a study published in Nature Communications, Dr...
A maternal junk food diet alters development of opioid pathway in the offspring
Date: Aug-02-2013Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, shows that eating a junk-food diet during pregnancy changes the development of the opioid signalling pathway in the baby's brain and permanently alters the way this system operates after birth. Opioids are chemicals which are released when we eat foods that are high in fat and sugar, and that are responsible for causing the release of another 'feel good' chemical, dopamine...
India's research participant protection policy - BMJ editorial
Date: Aug-02-2013In an editorial published online in BMJ, bioethicist Jeremy Sugarman and other experts warn that action is urgently needed to deal with possible unintended consequences of India's new policy to protect research participants. Passed earlier this year, the Drugs and Cosmetics Act (First Amendment) Rules, was meant to mitigate ethical concerns with potential serious consequences for public health, as well as India's viability as a continued global leader in clinical research...
New 3-D colonoscopy eases detection of precancerous lesions
Date: Aug-02-2013MIT researchers have developed a new endoscopy technology that could make it easier for doctors to detect precancerous lesions in the colon. Early detection of such lesions has been shown to reduce death rates from colorectal cancer, which kills about 50,000 people per year in the United States. The new technique, known as photometric stereo endoscopy, can capture topographical images of the colon surface along with traditional two-dimensional images...
Rubber slat mats could improve swine health, reduce locomotory problems for pregnant gilts
Date: Aug-02-2013New research shows that rubber slat mats could improve swine health. In a new study in the Journal of Animal Science, researchers in Europe studied how different types of flooring affects claw and limb lesions, locomotion and flooring cleanliness. According to the researchers, flooring is one of the main factors in production systems that cause locomotory problems in swine. Locomotory problems can be caused by joint injuries or by circulatory problems in the legs and feet...
Boomers hit hardest by 'Great Recession' in California
Date: Aug-02-2013A new study shows what many middle-aged Californians privately suspect: They are the first to lose their jobs and the health benefits that come with those jobs when hard times hit. The analysis by the UCLA Center for Health Policy Research looked at California data on the uninsured between 2007 and 2009 and found that of the approximately 700,000 Californians to lose health insurance during this time, the greatest increase was among residents between the ages of 45 and 64...
Brain maps to benefit epileptic surgery
Date: Aug-02-2013A brain imaging research team led by Simon Fraser University neuroscientist Dr. Ryan D'Arcy has found a new way to help surgeons more accurately plan for surgical treatment in epilepsy. The results of a recent study using magnetoencephalography (MEG) have been published in the field's highest impact journal, Human Brain Mapping. To showcase the study, the journal highlighted the novel images of MEG activity on the August 2013 cover...
Fetal Alcohol Spectrum Disorder (FASD) impacts brain development throughout childhood and adolescence not just at birth
Date: Aug-02-2013Medical researchers at the University of Alberta recently published findings showing that brain development is delayed throughout childhood and adolescence for people born with Fetal Alcohol Spectrum Disorder (FASD). Christian Beaulieu and Carmen Rasmussen, the two primary investigators in the research study, recently published the results of their work in the peer-reviewed journal, The Journal of Neuroscience. Their team scanned 17 people with FASD, and 27 people without the disorder, who were between 5 and 15 years old...
