Oral bacteria may contribute to the development of obesity

The world-wide explosion of overweight people has been called an epidemic. The inflammatory nature of obesity is widely recognized. Could it really be an epidemic involving an infectious agent? In this climate of concern over the increasing prevalence of overweight conditions in our society, investigators have focused on the possible role of oral bacteria as a potential direct contributor to obesity.

Cells use import machinery to export their goods as well

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory.

Dental problems may predict future medical issues

Dental disease may be a wake-up call that your diet is harming your body. "The five-alarm fire bell of a tooth ache is difficult to ignore," says Dr. Philippe P. Hujoel, professor of dental public health sciences at the University of Washington (UW) School of Dentistry in Seattle. Beyond the immediate distress, dental pain may portend future medical problems. It may be a warning that the high-glycemic diet that led to dental problems in the short term may, in the long term, lead to potentially serious chronic diseases.

Newborn brain cells improve our ability to navigate our environment

Although the fact that we generate new brain cells throughout life is no longer disputed, their purpose has been the topic of much debate. Now, an international collaboration of researchers made a big leap forward in understanding what all these newborn neurons might actually do. Their study, published in the July 10, 2009, issue of the journal Science, illustrates how these young cells improve our ability to navigate our environment.

Two reproductive factors are important predictors of death from ovarian cancer

Researchers from the Centers for Disease Control and Prevention (CDC) found that survival among women with ovarian cancer is influenced by age of menarche and total number of lifetime ovulatory cycles.

New heart disease risk score outperforms existing test

An independent external validation of QRISK® - a new score for predicting a person's risk of heart disease - has shown that it performs better than the existing test and should be recommended for use in the United Kingdom by the National Institute for Health and Clinical Excellence (NICE).

Relationship between migraine history and breast cancer risk among premenopausal and postmenopausal women

The relationship between migraine headaches in women and a significant reduction in breast cancer risk has been confirmed in a follow-on study to landmark research published last year and conducted by scientists at Fred Hutchinson Cancer Research Center. The new study found a 26 percent reduced risk of breast cancer among both premenopausal and postmenopausal women with a clinical diagnosis of migraines.

Research may hold key to maintaining embryonic stem cells in lab

In a new study that could transform embryonic stem cell (ES cell) research, scientists at UT Southwestern Medical Center have discovered why mouse ES cells can be easily grown in a laboratory while other mammalian ES cells are difficult, if not impossible, to maintain.

Family Research Council President says NIH stem cell guidelines ethically irresponsible

Today, Family Research Council President Tony Perkins responded to the National Institutes of Health (NIH) guidelines implementing President Obama's executive order for federal funding of human embryonic stem cell research (ESCR). President Obama's order and the NIH guidelines remove life-protecting limits on federal funding of embryonic stem cell research.

Multiple session early psychological interventions for the prevention of post-traumatic stress disorder

Psychological interventions intended to prevent the development of post-traumatic stress disorder (PTSD) in the early stages after a traumatic experience have not been shown to be effective, Cochrane Researchers have concluded. This systematic review focused on multiple-session treatments for everyone involved, irrespective of the presence of symptoms. Two previous reviews found single session interventions to be ineffective.

Treatment blood pressure targets for hypertension

Aiming for lower than standard blood pressure targets offers no known clinical benefit, according to a Cochrane Review. In a systematic review of the evidence, researchers found that using antihypertensive drugs to reduce blood pressure below the 140/90 mm Hg standard was not associated with any reduction in death rates or serious morbidity.
