FaME38: Helping engineers studying critical materials
Airplane wings or railway rails are examples of mechanical components constantly submitted to stress. They consist of materials (metal alloys) with properties that may change under stress. To understand and improve such materials, it is essential to observe them on a microscopic scale. The ESRF and... view more (2002-11-26)

Nanotechnology boosts war on superbugs
This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at UCL are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant... view more (2008-10-13)

'Motherwell's babies' study may yield up clues for adult diseases
Researchers from the Universities of Southampton and Edinburgh have begun a new study into the effects of a mother's diet in pregnancy upon unborn babies and their future health. The research team will seek answers to the links between diet and health by carrying out further studies in a group of... view more (2005-04-11)

Heavy Metal Rocks Plant Cells too
Heavy metals can trigger widely varying stress reactions in plants. A team at the Campus Vienna Biocenter was now able to provide evidence for this in a research funded by the Austrian Science Fund (FWF). The results, now awaiting publication, are an important basis to comprehend how plants cope... view more (2004-09-22)

Genetic pathway critical to disease, aging found
The same chemical reaction that causes iron to rust plays a similarly corrosive role in our bodies. Oxidative stress chips away at healthy cells and is a process, scientists know, that contributes to a host of diseases and conditions in humans ranging from Alzheimer's, heart disease and stroke to... view more (2008-02-21)

Sudden death from stress linked to wonky signals in the brain
Sudden cardiac death from emotional stress may be triggered by uneven signals from the brain to the heart, according to a study by University College London (UCL) scientists published in the January issue of Brain.   view more (2004-12-23)

New Study Finds Uncontrollable Stress Worsens Symptoms Of Endometriosis
Endometriosis is a poorly understood condition that incapacitates and affects the productivity and lifestyle of millions of women around the world. In the US, it affects approximately six million women and adolescents at a cost of some $1.6 billion per year.   view more (2008-04-08)

New research suggests heart bypass surgery increases risk of Alzheimer's disease
Boston University School of Medicine (BUSM) researchers have discovered that patients who have either coronary artery bypass graft surgery or coronary angioplasty are at an increased risk of developing Alzheimer's disease.   view more (2005-08-26)

Pre-clinical study suggests how steroid can reverse post-traumatic stress
Researchers at UT Southwestern Medical Center, working with mice, have shown how the body's own natural stress hormone can help lastingly decrease the fearful response associated with reliving a traumatic memory.   view more (2006-09-13)

New study: Pine bark extract reduces ADHD symptoms in children
Attention Deficit Hyperactivity Disorder (ADHD) is a prevailing issue in the United States, with millions of children getting diagnosed every year. A new study reveals that Pycnogenol, (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree, reduces ADHD in... view more (2007-09-13)

DO POST-MENOPAUSAL WOMEN REALLY NEED CERVICAL SMEAR TESTS ?
In the United Kingdom postmenopausal women who are at little risk of developing cervical cancer remain in the screening programme until the age of 64. In this week's BMJ, Chris Sherlaw-Johnson and colleagues from University College London and Queen's Medical Centre, Nottingham use a mathematical... view more (1999-02-02)

New compound prevents alcoholic behavior, relapse in animals by blocking stress response
A study of alcohol-dependent animals shows that a newly discovered compound that blocks chemical signals active during the brain's response to stress effectively stops excessive drinking and prevents relapse.   view more (2007-03-07)

Vitamin E trials 'fatally flawed'
Generations of studies on vitamin E may be largely meaningless, scientists say, because new research has demonstrated that the levels of this micronutrient necessary to reduce oxidative stress are far higher than those that have been commonly used in clinical trials.   view more (2007-09-24)

Stress tests to confirm need for cardiac stent not occurring in most patients, new study finds
UCSF researchers investigating the appropriate use of procedures to open narrowed coronary arteries -- such as angioplasty and stenting -- found that less than half of Medicare patients had documented noninvasive stress testing prior to elective percutaneous coronary intervention, or PCI, the... view more (2008-10-15)

Haunted by hallucinations: Children in the PICU traumatized by delusions
Nearly one in three children admitted to pediatric intensive care will experience delusions or hallucinations, which put them at higher risk for post-traumatic stress symptoms, according to a new study of children's experiences in a pediatric intensive care unit (PICU).   view more (2008-05-01)

First molecular evidence of body's internal clock in controlling blood pressure
It has been known for decades that heart attacks and strokes occur most frequently in the early-morning hours. Now, researchers at the University of Pennsylvania School of Medicine have provided the first evidence for the role of our body's internal molecular clock in controlling blood pressure and... view more (2007-02-20)

A higher risk of obesity for children neglected by parents
Strategies for decreasing a child's risk for obesity often focus on improving eating habits and maintaining a high level of physical activity.   view more (2007-11-14)

Inflammatory genes linked to salt-sensitive hypertension
One key to your high blood pressure might just be your inflammatory genes. It may sound odd but mounting evidence suggests that inflammation, a part of the immune response implicated in diseases such as cancer, Alzheimer's and diabetes, may also help translate stress into high blood pressure.   view more (2006-12-28)

Mental stress reduces blood flow to the heart in patients with gene variation
University of Florida researchers have identified a gene variation in heart disease patients who appear especially vulnerable to the physical effects of mental stress - to the point where blood flow to the heart is greatly reduced.   view more (2008-04-16)

Partners of frequent business travellers three times as likely to suffer metal health problems
The spouses of frequent international business travellers have three times the levels of stress related psychological problems of those whose partners stay at home, shows research in Occupational and Environmental Medicine.   view more (2002-03-04)

EMOTIONAL PROBLEMS OF CHILDREN LIVING IN WAR ZONES NOT RECOGNISED (PP 1790, 1801)
Health professionals need to be trained in the detection and treatment of the emotional disturbances associated with   children's exposure to war zones and political violence, conclude authors of a study in this week's issue of THE LANCET. Children living in war zones are at a high... view more (2002-05-22)

Phytochemicals may protect cartilage, prevent pain in joints
Johns Hopkins researchers have discovered that plant-derived compounds known for their ability to protect tissue also appear to block the activity of an enzyme that triggers inflammation in joints.   view more (2005-10-04)

Coping and copulation behavior may help calculate diabetes risk
Discussion of a man's background, attitude, and sexual history isn't just the fodder of Sex and The City episodes - in the future, it could also be a way of evaluating his risk of diabetes.   view more (2008-11-06)

Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection
