School Mental Health Providers Play A Critical Role In Early Identification And Referral For Adolescents
Date: May-09-2013A study published in the May 2013 issue of the Journal of the American Academy of Child and Adolescent Psychiatry found that mental health resources provided by schools are significantly associated with whether adolescents with mental disorders receive needed mental health services. In particular, adolescents with disorders attending schools that engage in early identification of emotional problems, are significantly more likely to receive mental health services. Using data from the National Comorbidity Survey Replication Adolescent Supplement (NCS-A), a group of researchers led by Dr...
Breast Cancer Risk May Be Reduced By Exercise-Related Changes In Estrogen Metabolism
Date: May-09-2013Changes in estrogen breakdown, or metabolism, may be one of the mechanisms by which aerobic exercise lowers a woman's breast cancer risk, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. "Observational studies suggest physical activity lowers breast cancer risk, but there are no clinical studies that explain the mechanism behind this," said Mindy S. Kurzer, Ph.D., professor in the Department of Food Science and Nutrition at the University of Minnesota in Saint Paul...
Lung Inflammation Caused By Ubiquitous Engineered Nanomaterials
Date: May-09-2013A consortium of scientists from across the country has found that breathing ultrafine particles from a large family of materials that increasingly are found in a host of household and commercial products, from sunscreens to the ink in copy machines to super-strong but lightweight sporting equipment, can cause lung inflammation and damage. The research on two of the most common types of engineered nanomaterials is published online in Environmental Health Perspectives, the journal of the National Institute of Environmental Health Sciences (NIEHS)...
Reducing Dangers Of Lead Poisoning
Date: May-09-2013A new study appearing this week in the Journal of Health Politics, Policy, and Law catalogues community-based efforts to develop strategies and policies that - by targeting high risk housing - may hold the key to reducing lead hazards in children's homes. "Lead poisoning has long been characterized as a health problem with a housing solution," said Katrina Korfmacher, Ph.D., director of the Community Outreach and Engagement Core of the University of Rochester Medical Center (URMC) Environmental Health Sciences Center and co-author of the study...
Revealing The Cross-Cultural Implications Of Suicide
Date: May-09-2013Just over a month ago, a young high school student from Halifax committed suicide after photos of her being raped were posted on the Internet. Her story wasn't just about bullying. It was also about the complex feelings her friends and family faced with her decision to take her own life. Such a reaction is common to cultures around the word. New research from Concordia University shows that, no matter where it occurs, a veil of shame and sense of taboo surround suicide. These attitudes often force those affected to grieve alone and can produce feelings of helplessness and despair...
A Living Patch For Damaged Hearts
Date: May-09-2013Duke University biomedical engineers have grown three-dimensional human heart muscle that acts just like natural tissue. This advancement could be important in treating heart attack patients or in serving as a platform for testing new heart disease medicines. The "heart patch" grown in the laboratory from human cells overcomes two major obstacles facing cell-based therapies - the patch conducts electricity at about the same speed as natural heart cells and it "squeezes" appropriately. Earlier attempts to create functional heart patches have largely been unable to overcome those obstacles...
Protecting Preterm Infants From Disturbing Light
Date: May-09-2013Preterm infants appear to mature better if they are shielded from most wavelengths of visible light, from violet to orange. But it has been a challenge to develop a controllable light filter for preterm incubators that can switch between blocking out all light - for sleeping - and all but red light to allow medical staff and parents to check up on the kids when they're awake...
New Cause Discovered For Common Lung Problem
Date: May-09-2013New research has found that in cases of lung edema, or fluid in the lungs, not only do the lungs fail to keep water out as previously believed, but they are also allowing water to pump in. "Usually, our lungs pump fluid out of the air space, and it was previously believed that this pump mechanism just stopped when people had lung edema," said Dr. Wolfgang Kuebler, a scientist at St. Michael's Hospital. "But we've found not only do they stop pumping fluid out as they're supposed to do, they've gotten confused and are actually pumping in the reverse direction, bringing fluid into the lungs...
Endogenous Antibiotic Discovered In The Brain
Date: May-09-2013Scientists from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg have discovered that immune cells in the brain can produce a substance that prevents bacterial growth: namely itaconic acid. Until now, biologists had assumed that only certain fungi produced itaconic acid. A team working with Dr. Karsten Hiller, head of the Metabolomics Group at LCSB, and Dr. Alessandro Michelucci has now shown that even so-called microglial cells in mammals are also capable of producing this acid. "This is a ground breaking result," says Prof. Dr...
Laughter Perception Networks In Brain Different For Mocking, Joyful Or Ticklish Laughter
Date: May-08-2013Cerebral connectivity patterns differ based on auditory, social information in laughter A laugh may signal mockery, humor, joy or simply be a response to tickling, but each kind of laughter conveys a wealth of auditory and social information. These different kinds of laughter also spark different connections within the "laughter perception network" in the human brain depending on their context, according to research published May 8 in the open access journal PLOS ONE by Dirk Wildgruber and colleagues from the University of Tuebingen, Germany...
