Relationship between environmental stress and cancer elucidated
One way environmental stress causes cancer is by reducing the activity level of an enzyme that causes cell death, researchers say. view more (2007-11-06)
New evidence that dark chocolate helps ease emotional stress
The "chocolate cure" for emotional stress is getting new support from a clinical trial published online in ACS' Journal of Proteome Research. view more (2009-11-12)
Ceramic/metal interface fracture toughness
Ceramic/metal joints have been increasingly applied in a wide range of engineering fields because the ceramic has stable mechanical properties at high temperature and good resistance to wear, erosion and oxidation. view more (2005-09-29)
High levels of daily stress may result in lower risk of breast cancer
High levels of daily stress appear to result in a lower risk of developing breast cancer for the first time, says a study in this week's BMJ. view more (2005-09-09)
Seniors with type 2 diabetes may experience memory declines immediately after eating unhealthy meal
Adults with type 2 diabetes who eat unhealthy, high-fat meals may experience memory declines immediately afterward, but this can be offset by taking antioxidant vitamins with the meal, according to new research from Baycrest. view more (2008-06-26)
Stress causes parodontis
Under stress, major proteins get actively destroyed in the parodentium. According to biologists' data, chronical stress inhibits the osseous tissue maturing process and intensifies decomposition of collagen protein and proteoglycans with the animals non-resistant to stress. Stress intensifies hydrolysis of proteins, which make the basis of the... view more... (2003-09-26)
Link between stress and heart disease may be premature
It has often been claimed that psychological stress is an important cause of heart disease, but a study in this week's BMJ shows that previous research may have been misleading. Researchers measured self-assessed stress amongst middle-aged Scottish men working in and around Glasgow in the early 1970s. These men were then followed for more than... view more... (2002-05-22)
Controlling body size by regulating the number of cells
Why are elephants bigger than mice? The main reason is that mice have fewer cells. Research published in Journal of Biology this week uncovers a key pathway that controls the number of cells in an animal, thereby controlling its size. Ernst Hafen and his colleagues from the University of Zürich used fruit flies to investigate the role of the... view more... (2003-08-05)
Insulin receptor stops progression of Alzheimer's disease
Stimulation of a receptor in the brain that controls insulin responses has been shown to halt or diminish the neurodegeneration of Alzheimer's disease, providing evidence that the disease can be treated in its early stages. view more (2006-09-22)
Antioxidants may protect against tick-borne illness
Researchers are investigating the role that antioxidants - alpha-lipoic acid and potentially others like green tea and vitamins C and E, for example - might play in preventing or treating the deadly rickettsia bacteria. view more (2006-08-10)
Chloroplast f and m Thioredoxins Discovered in Nonphotosynthetic Tissues
Thioredoxins (TRXs) are a large family of small proteins that function in multiple metabolic processes in all living organisms. They are a good example of proteins that have diversified throughout evolution, probably from one ancestral protein that arose in ancient cyanobacteria. view more (2007-10-16)
Women suffer less stress than men thanks to their hormones, according to study
Women seem to be less susceptible than men to stress and serious stress-related illnesses because of the protective properties of the sex hormone oestrogen, according to a recent study of nurses by the University of Greenwich. The study indicates that oestrogen reduces the production of stress hormones such as cortisol and adrenaline which, when... view more... (2002-10-15)
Does the stress of being a parent lead to decay in children's teeth?
A team of scientists from The Ohio State University has examined the stress levels of parents whose young children either had no cavities or so many cavities that the children had receive anesthesia before undergoing dental treatment. view more (2009-04-06)
Lifestyle can alter gene activity, lead to insulin resistance
A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy. view more (2008-06-19)
Study shows a bidirectional relationship between chronic stress and sleep problems
People with chronic stress report shorter sleep duration, worse sleep quality, and more daytime functioning impairments. view more (2009-06-10)

Chronic stress, depression and cortisol levels are potential risk indicators for periodontal disease
Caregivers of people under psychological or physical stress, as well as those with the conditions themselves, should not overlook their oral health, according to a new study printed in the Journal of Periodontology. view more (2006-06-01)
Why does stress make us ill?
How stress can make people ill was explored in a symposium organised by Professor Andrew Steptoe, University College London and Dr Marcel Ebrecht, Kings College London, today, Friday 7 September, at the joint British Psychological Society’s Division of Health Psychology and European Health Psychology Society conference, held at St Andrews... view more...

Helping Tomatoes Cope With Stress May Be Good For Us
Scientists at the John Innes Centre (JIC)(1) and Institute of Food Research (IFR)(2), Norwich, have today reported the discovery and use of a gene that may help protect plants and humans against disease. The gene (HQT) was identified in tomato and is responsible for producing an antioxidant called chlorogenic acid (CGA). By increasing the... view more... (2004-04-26)
New hereditary gene linked to Parkinson's disease
UCL scientists have discovered a new gene implicated in the early development of Parkinson's disease. In a study of families with early onset disease, Professor Nick Wood and colleagues at UCL's Institute of Neurology identified a novel gene which produces a malfunctioning protein that could pave the way for new treatments for Parkinson sufferers.... view more...
