Children living in poverty who appear to succeed socially may be failing biologically. Students able to overcome the stress of growing up poor are labeled "resilient" because of their ability to overcome adversity, but University of Georgia researchers found this resiliency has health costs that last well into adulthood. http://medicalxpress.com/news/2013-05-uncovers-resiliency-kids.html Psychology & Psychiatry Thu, 30 May 2013 11:23:34 EST news289131805 Scientists at the Salk Institute for Biological Studies have identified a protein that drives the formation of pituitary tumors in Cushing's disease, a development that may give clinicians a therapeutic target to treat this potentially life-threatening disorder. http://medicalxpress.com/news/2013-05-scientists-potential-therapeutic-cushing-disease.html Diseases, Conditions, Syndromes Tue, 07 May 2013 16:11:18 EST news287161860 Making more use of in-vitro testing, the upcoming 21st-century scientific fields known as 'omics' sciences and developing smart test strategies can clearly reduce the amount of essential animal testing. This is the view of Professor Bennard van Ravenzwaay in his inaugural speech on accepting the endowed chair in Reproduction and Developmental Toxicology at Wageningen University on 2 May. His chair will be funded by BASF and is part of the sub-department of Toxicology. http://medicalxpress.com/news/2013-05-methods-amount-animal.html Medical research Tue, 07 May 2013 08:50:03 EST news287135129 (HealthDay)—Children with lower levels of daytime physical activity (PA) have higher hypothalamic-pituitary-adrenocortical axis (HPAA) activity in response to psychosocial stress, suggesting that PA may help children cope with stressful situations, according to research published online March 7 in the Journal of Clinical Endocrinology & Metabolism. http://medicalxpress.com/news/2013-03-higher-children-stress.html Health Fri, 29 Mar 2013 13:54:37 EST news283784071 New research from the University of North Carolina School of Medicine for the first time explains exactly how two brain regions interact to promote emotionally motivated behaviors associated with anxiety and reward. http://medicalxpress.com/news/2013-03-brain-areas-interact-trigger-divergent.html Neuroscience Wed, 20 Mar 2013 14:00:01 EST news283000101 Some 2-year-olds whose moms used methamphetamine during pregnancy may have an abnormal response to stressful situations, according to a study in the May issue of the Journal of Studies on Alcohol and Drugs. http://medicalxpress.com/news/2013-03-abnormal-stress-response-toddlers-exposed.html Addiction Wed, 20 Mar 2013 00:10:04 EST news282938731 Exercise may play a key role in helping children cope with stressful situations, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). http://medicalxpress.com/news/2013-03-shields-children-stress.html Health Thu, 07 Mar 2013 11:16:43 EST news281877395 A five-year study by researchers at three universities has established that providing tangible assistance to others protects our health and lengthens our lives. http://medicalxpress.com/news/2013-02-healthier.html Psychology & Psychiatry Mon, 04 Feb 2013 17:35:41 EST news279221733 It 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. http://medicalxpress.com/news/2013-01-childhood-trauma-brain.html Psychology & Psychiatry Tue, 15 Jan 2013 04:24:20 EST news277446252 A recent study by a researcher at the Centre for Studies on Human Stress (CSHS) at the Hôpital Louis-H. Lafontaine and professor at the Université de Montréal suggests that bullying by peers changes the structure surrounding a gene involved in regulating mood, making victims more vulnerable to mental health problems as they age. http://medicalxpress.com/news/2012-12-bullying-childhood-peers-gene-linked.html Psychology & Psychiatry Tue, 18 Dec 2012 04:38:42 EST news275027909 Even before obesity occurs, eating fatty and sugary foods causes chemical changes in the brain, meaning that going on a diet might feel similar to going through drug withdrawal, according to a study published today by Dr. Stephanie Fulton of the University of Montreal's Faculty of Medicine and its affiliated CRCHUM Hospital Research Centre. "By working with mice, whose brains are in many ways comparable to our own, we discovered that the neurochemistry of the animals who had been fed a high fat, sugary diet were different from those who had been fed a healthy diet," Fulton explained. "The chemicals changed by the diet are associated with depression. A change of diet then causes withdrawal symptoms and a greater sensitivity to stressful situations, launching a vicious cycle of poor eating." http://medicalxpress.com/news/2012-12-fatty-food-habit-symptoms-depression.html Overweight and Obesity Wed, 12 Dec 2012 04:24:51 EST news274508677 Posttraumatic stress disorder (PTSD) is a form of learning that begins at the moment of the exposure to extremely stressful situations and that grows in impact as trauma-related memories are rehearsed and strengthened repeatedly. This somewhat oversimplified view of PTSD yields a powerful prediction: if one could disrupt the rehearsal and strengthening of traumatic memories, a process called reconsolidation of memories, then one might reduce PTSD risk or PTSD severity after potentially traumatic events. http://medicalxpress.com/news/2012-11-posttraumatic-stress-disorder-trauma-memories.html Psychology & Psychiatry Tue, 27 Nov 2012 09:54:56 EST news273232483 Bad news articles in the media increase women's sensitivity to stressful situations, but do not have a similar effect on men, according to a study undertaken by University of Montreal researchers at the Centre for Studies on Human Stress of Louis-H.

In the study, the results of which the team has published in the Proceedings of the National Academy of Sciences, the team writes that stressful events can lead to increased production of cytokines, molecules that are produced when inflammation occurs. http://medicalxpress.com/news/2012-01-negative-social-interactions-amounts-internal.html Medical research Tue, 24 Jan 2012 06:50:05 EST news246610186 (Medical Xpress) -- Women with celiac disease -- an autoimmune disorder associatedwith a negative reaction to eating gluten -- are more likely than the general population to report symptoms of depression and disordered eating, even when they adhere to a gluten-free diet, according to researchers at Penn State, Syracuse University and Drexel University. http://medicalxpress.com/news/2011-12-women-celiac-disease-depression-disordered.html Diseases, Conditions, Syndromes Mon, 26 Dec 2011 10:10:55 EST news244116630 A 15-minute walk can cut snacking on chocolate at work by half, according to research by the University of Exeter.

Such behaviors are called endophenotypes. Now, researchers at the California Institute of Technology (Caltech) have found that mice lacking a gene that encodes a particular protein found in the synapses of the brain display a number of endophenotypes associated with schizophrenia and autism spectrum disorders. http://medicalxpress.com/news/2011-11-scientists-link-synapse-protein-abnormal.html Neuroscience Wed, 23 Nov 2011 08:55:51 EST news241260929 If either of your parents has a drink problem, there is a greater risk that you will consume more alcohol after stressful situations, reveals current research from the Sahlgrenska Academy, at the University of Gothenburg, Sweden. http://medicalxpress.com/news/2011-09-stress-alcoholics-children.html Health Tue, 20 Sep 2011 11:05:03 EST news235735485
