Background

The hippocampal formation has long been associated with the execution of higher-order cognitive functions, and impairment of this structure following severe stress and aging has been linked to cognitive disturbances. In order to understand the involvement of the hippocampal formation in the mediation of normal and pathological behaviors, much attention has recently been devoted to hippocampal neurogenesis. The dentate gyrus of the hippocampal formation has the ability to g

A 33-year study of all births by women in Norway with Myasthenia Gravis (MG) confirms that MG is associated with an increased risk for complications during pregnancy, including a threefold higher incidence of preterm rupture of the amniotic membranes, and twice the occurrence of delivery by cesarean section. The study is reported in the November 25 issue of Neurology, the scientific journal of the American Academy of Neurology. Data for the study was collected from the Medical Birth Registry

A novel approach that combines gene therapy and radiation therapy for treating prostate cancer has shown promising results for its safety and effectiveness, according to Henry Ford Hospital researchers.

The study, published in this month’s edition of Cancer Research, shows that patients experienced no significant side effects when treated with gene therapy and radiation therapy. It also showed that the treatment lowered patients’ prostate-specific antigen (PSA) and eliminated the

A study by Duke University Medical Center researchers has found that women do not derive the same long-term quality-of-life benefits as men following coronary artery bypass surgery. This conclusion was evident even after the researchers statistically adjusted their data to allow for the greater number of preoperative risk factors in women than in men.

The researchers speculate that there may be two reasons for this clear gender discrepancy – either women may not experience the same level of

Use of caloric sweeteners, including sugar, has grown markedly around the world over the past 40 years, according to a new University of North Carolina at Chapel Hill study.

In the United States, UNC scientists found increasing consumption of beverages, including soft drinks and sugared fruit drinks, was a major contributor to the burgeoning use of such sweeteners, which nutritionists believe contribute to unhealthy obesity. Obesity boosts the risk of heart disease, stroke, diabetes and oth

Researchers suspect that the number of people infected during the recent Midwest outbreak may be higher than first reported

Researchers at Oregon Health & Science University are trying to gain a better understanding of last summer’s monkeypox outbreak. The researchers traveled to the Midwest twice during the past few months to obtain blood samples from residents exposed to the disease. A third trip is planned for December. The samples will be used to better understand the human i
