Risk of accelerated aging seen in PTSD patients with childhood trauma (5/2/2011)

Adults with post-traumatic stress disorder and a history of childhood trauma had significantly shorter telomere length than those with PTSD but without childhood trauma, in a study by researchers at the San Francisco VA Medical Center and the University of California, San Francisco. ...> Full Article

Call of the riled (4/21/2011)

Researchers at the University of California, San Diego School of Medicine say a "stress response" mechanism used by normal cells to cope with harsh or demanding conditions is exploited by cancer cells, which transmit the same stress signal to surrounding cells, triggering an inflammatory response in them that can aid tumor growth. ...> Full Article

Stress before cancer therapy could help deadly cells survive treatment, lead to disease recurrence (9/28/2010)

Patients who experience physical or psychological stress -- including rigorous exercise -- one or two days before a cancer treatment might be unknowingly sabotaging their therapy, new research suggests. Stress in the body -- even physical stress caused by intense exercise -- activates a stress-sensitive protein that can spark a series of events that allow cancer cells to survive such treatments as chemotherapy and radiation, according to the research. ...> Full Article

Don't worry, be happy! Positive emotions protect against heart disease (2/19/2010)

People who are usually happy, enthusiastic and content are less likely to develop heart disease than those who tend not to be happy, according to a major new study published on Thursday 18 February. The authors believe that the study, published in the Europe's leading cardiology journal, the European Heart Journal, is the first to show such an independent relationship between positive emotions and coronary heart disease. ...> Full Article

Stress triggers tumor formation, researchers find (1/18/2010)

Stress induces signals that cause cells to develop into tumors, Yale researchers have discovered. The research, published online Jan. 13 in the journal Nature, describes a novel way cancer takes hold in the body and suggests new ways to attack the deadly disease. ...> Full Article

Severe stress can cause stroke (10/4/2009)

Many patients urgently admitted to hospital with cerebral infarction state that they were under great stress over a prolonged period prior to suffering their stroke, is shown in a unique patient study conducted in cooperation between the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital, Sweden. ...> Full Article

Genetically engineered mice yield clues to 'knocking out' cancer (7/4/2009)

Researchers from NIST, Oregon Health and Science University and the New York University School of Medicine have demonstrated that deleting two genes in mice responsible for repairing DNA strands damaged by oxidation leads to several types of tumors, providing additional evidence that such stress contributes to the development of cancer. The work may lead to the development of new measurement methods and reference materials for accurate and reproducible assessments of DNA damage and repair. ...> Full Article

Anti-aging pathway enhances cell stress response (2/24/2009)

A Northwestern University-led research team has discovered a new molecular relationship critical to keeping cells healthy across a long span of time: a protein called SIRT1, important for caloric restriction and lifespan and activated by resveratrol, regulates heat shock factor 1 (HSF1), keeping it active. HSF1 in turn senses the presence of damaged proteins in the cell and elevates the expression of molecular chaperons to keep a cell's proteins in a folded, functional state. ...> Full Article

Researchers make new discoveries on what does and doesn't affect immune system (2/5/2008)

Scientists know that a number of factors can affect the body's immune system: poor diet, certain steroids, chronic stress.

Understanding Role Of Stress In Just About Everything (1/14/2008)

Stress, to put it bluntly, is bad for you. It can kill you, in fact. A study now reveals that stress causes deterioration in everything from your gums to your heart and can make you more susceptible to everything from the common cold to cancer. Thanks to new research crossing the disciplines of psychology, medicine, neuroscience, and genetics, the mechanisms underlying the connection are rapidly becoming understood. ...> Full Article
