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.

Burning incense ups the risk of respiratory tract cancers

New research is suggesting that using incense for long periods could increase the risk of developing cancers of the respiratory tract.

Premature births may be the result of undiagnosed infection

Scientists in the U.S. say a significant number of premature births may be caused by infections which are undiagnosed and the heavier the infection, the more likely the women were to deliver younger, sicker babies.

Childhood pets may make adults snorers

New research into why people snore has found that the roots of the problem possibly go back to a person's childhood.

Asian-American/Pacific Islanders have higher survival rates than others for gastric cancers

Asian-American/Pacific Islanders with early-stage stomach cancers have an overall median survival rate that is higher than those of other races or ethnicities, according to new research, Reuters Health reports.

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.

Infections of amniotic fluid may be a significant cause of premature birth

Previously unrecognized and unidentified infections of amniotic fluid may be a significant cause of premature birth, according to researchers at the Stanford University School of Medicine.

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.

Breakthrough discovery may lead to new drugs to fight bird flu, other epidemics

Researchers at Rutgers University and The University of Texas at Austin have reported a discovery that could help scientists develop drugs to fight the much-feared bird flu and other virulent strains of influenza.

How memory deals with a change in plans

You're about to leave work at the end of the day when your cell phone rings: it's your spouse, asking that you pick up a gallon of milk on the way home. Before you head out the door, though, your spouse calls again and asks you to stop by the hardware store too. Based on your knowledge of the area and rush-hour traffic, you decide to get the milk first and the toilet plunger second. But whoops! The phone rings again. This time, it's your boss, asking you to work late. That means another change of plans.

Long term use of incense increases the risk of developing cancers of the respiratory tract

Long term use of incense increases the risk of developing cancers of the respiratory tract, according to a new study. The new analysis, which the authors say is the first prospective investigation of incense and cancer risk, appears in the October 1, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society.

Alcohol consumption can cause too much cell death, fetal abnormalities

The initial signs of fetal alcohol syndrome are slight but classic: facial malformations such as a flat and high upper lip, small eye openings and a short nose.

Century old rule of chemistry overturned - major implications for drug delivery

A new study by research chemists at the University of Warwick has challenged a century old rule of pharmacology that defined how quickly key chemicals can pass across cell walls. The new observations of the Warwick researchers suggest that the real transport rates could be up to a hundred times slower than predicted by the century old "Overton's Rule". This could have major implications for the development and testing of many future drugs.

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.
