Chronic stress alters our genetic immune response

Most people would agree that stress increases your risk for illness and this is particularly true for severe long-term stresses, such as caring for a family member with a chronic medical illness. However, we still have a relatively limited understanding of exactly how stress contributes to the risk for illness. In the August 15th issue of Biological Psychiatry, researchers shed new light on one link between stress and illness by describing a mechanism through which stress alters immune function.

Potential new targets for antidepressants

The news about antidepressant medications over the past several years has been mixed. The bad news from large multicenter studies such as STAR*D is that current antidepressant medications are effective, but not as effective as one might hope. Thus, there is a significant need for new treatment mechanisms for depression. On that front, there has been mixed news as well.

Global survey highlights need for cancer prevention campaigns to correct misbeliefs

Many people hold mistaken beliefs about what causes cancer, tending to inflate the threat from environmental factors that have relatively little impact while minimizing the hazards of behaviours well established as cancer risk factors, according to the first global survey on the topic.

Normalizing tumor vessels to improve chemotherapy drug delivery

Chemotherapy drugs often never reach the tumors they're intended to treat, and radiation therapy is not always effective, because the blood vessels feeding the tumors are abnormal-"leaky and twisty" in the words of the late Judah Folkman, MD, founder of the Vascular Biology program at Children's Hospital Boston.

Could a substance from the jasmine flower hold the key to an effective new therapy to treat cancer?

Prof. Eliezer Flescher of The Sackler Faculty of Medicine, Tel Aviv University thinks so. He and his colleagues have developed an anti-cancer drug based on a decade of research into the commercial applications of the compound Jasmonate, a synthetic compound derived from the flower itself.

Study reveals how blood flow force protects against atherosclerosis

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the cause of clogged arteries that lead to heart attack and stroke, the authors said. The next set of studies, already underway, seeks to "tweak" the process with the goal of designing a new class of therapies.

Why hormone therapy for prostate cancer fails

Some of the drugs given to many men during their fight against prostate cancer can actually spur some cancer cells to grow, researchers have found. The findings were published online this week in a pair of papers in the Proceedings of the National Academy of Sciences.

A fitness test for DNA

Unusually high levels of physical exertion do cause oxidative stress, but this does not result in any long-term damage to DNA. This is just one of the many outcomes revealed by an extraordinary research project funded by the Austrian Science Fund FWF that are now published. As part of this project, 42 male athletes took part both in a triathlon and an extensive biomedical study, which examined numerous physiological values parameters during the period from two days before to 19 days after the triathlon.

Alcohol's effects on childbearing onset across reproductive development

Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has found that AD in women is associated with delayed reproduction.

Americanization linked to depression in immigrant women

A study of 439 U.S. and Mexican-born Latinas seeking pregnancy and postpartum services at public health clinics in San Antonio uncovered elevated levels of depression among the more "Americanized" women, report researchers from The University of Texas School of Public Health and The University of Texas Health Science Center at San Antonio in the most recent online issue of the Maternal and Child Health Journal.

COMT gene variation affects fear processing, anxiety

Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological Association.

Survey details New Orleans residents experiences three years after Hurricane Katrina

A comprehensive new Kaiser Family Foundation survey of the experiences of New Orleans residents - the second since Hurricane Katrina - reveals a still-struggling population that gives very mixed reviews in key areas of the recovery efforts. Most residents feel forgotten by the nation and its leaders, yet are still optimistic about their city's future.

Happiness makes you live longer

Happiness does not heal, but happiness protects against falling ill. As a result, happy people live longer. The size of the effect on longevity is comparable to that of smoking or not. This is concluded from an analysis of 30 follow-up studies published in the latest issue of the Journal of Happiness Studies (September 2008).
