Stress may leave your mouth a mess

A literature review published in the August issue of the Journal of Periodontology (JOP) saw a strong relationship between stress and periodontal diseases; 57% of the studies included in the review showed a positive relationship between periodontal diseases and psychological factors such as stress, distress, anxiety, depression, and loneliness.

"More research is needed to determine the definitive relationship between stress and periodontal diseases," said study author Daiane Peruzzo, PhD. "However, patients who minimize stress may be at less risk for periodontal diseases."

Some women benefit more from exercise when emphasis is on health, not appearance

A new study suggests that women with chronic issues with their body-image are more likely to benefit from an exercise class where the instructor emphasizes the health benefits of the workout over improved appearance, even if those women chose the class in hopes of improving their physique.

Researchers studied nearly 100 college-aged women who had social physique anxiety - a disorder in which someone chronically worries that others are critiquing his or her body.

Genetic variation helps to understand predisposition to schizophrenia

Scientists have provided new insight into how a gene is related to schizophrenia. In a study to be published in the August 17 issue of the Journal of Biological Chemistry, Amanda J. Law, Medical Research Council Fellow and Associate Professor at the University of Oxford, United Kingdom, and Visiting Scientist at the National Institutes of Health (NIH), along with colleagues at NIH describe for the first time a genetic variation that causes a gene to be overexpressed in the human brain. These results may provide a new way to design better drugs to treat schizophrenia.

"Although the exact causes of schizophrenia are yet to be determined, scientists agree that the disease is in part due to genetic variations," Law says. "These variations are not simple to understand because they don't directly disturb the function of proteins. In our study, we identified some clues as to what goes wrong with one of these DNA variations."

Electric Fields Kill Tumors

An Israeli company is conducting human tests for a device that uses weak electric fields to kill cancer cells but has no effect on normal cells. The device is in late-stage clinical trials in the United States and Europe for glioblastoma, a deadly brain cancer. It is also being tested in Europe for its effectiveness against breast cancer. In the lab and in animal testing, treatment with electric fields has killed cancer cells of every type tested.

Our Assumptions About What Causes Chronic Diseases Could Be Wrong

Discoveries about how chemicals and environmental toxins interact with our DNA and make us susceptible to disease could revolutionize our concept of illness.

Breast implants linked with suicide in study

Women who get cosmetic breast implants are nearly three times as likely to commit suicide as other women, U.S. researchers reported on Wednesday.

The study, published in the Annals of Plastic Surgery, reinforces several others that have shown women who have breast enlargements have higher suicide risks.

Hospitals Are Shutting Down Burn Centers

U.S. hospitals are increasingly shutting down their burn centers in a trend experts say could leave the nation unable to handle widespread burn casualties from a fiery terrorist attack or other major disaster.

Associated Press interviews and an examination of official figures found that the shrinking number of beds is a growing cause for concern in this post-Sept. 11 world.

Girls entering puberty by the age of six - but are drugs the answer?

Some girls now enter puberty as early as six - with toxic chemicals widely held to blame. But are new drugs to hold back the years really the right answer?:

Puberty is an unsettling stage in anyone's life, but if it happens at an age when you are still playing with dolls, it can be very worrying indeed.

That is exactly what happened to Lucia Reed. She was just seven when her periods started, an event which distanced Lucia from her classmates and led to unexplained medical examinations which terrified her.
