Assessment of dental ergonomics among dental students: A retrospective study.

Introduction: Musculoskeletal (MSK) disorders account for 11%-98% of occupational health issues for dental professionals, with an onset as early as in dental school. Dental ergonomics is among the risk factors; thus, a prompt assessment is crucial in preventing future MSK pain. The aim of this study was to retrospectively assess dental ergonomics of second-year dental students after dedicated lectures were introduced in the predoctoral curriculum.

Understanding the role of culture in domestic violence: the Ahimsa Project for Safe Families.

Domestic violence affects women across all racial, national, social, and economic groups. In particular, immigrant and refugee families are at risk for domestic violence because of their migration history and differences in cultural values and norms. The Ahimsa for Safe Families Project is an innovative collaborative project that addresses domestic violence in immigrant and refugee communities in San Diego.

Pyruvate improves myocardial tolerance to reperfusion injury by acting as an antioxidant: a chemiluminescence study.

Background: There is indirect evidence that pyruvate improves myocardial tolerance to ischemia by scavenging oxygen radicals during reperfusion. The objectives of this study were to evaluate (1) lucigenin-enhanced chemiluminescence (LEC) as a method to measure oxygen radical (OR) production in vitro and in vivo and (2) the antioxidant effect of pyruvate during myocardial reperfusion.

Methods: LEC was measured in vitro by adding to lucigenin (1) increasing concentrations of H2O2, (2) H2O2 and different concentrations of catalase, and (3) H2O2 plus pyruvate.

A prospective study of estrogen replacement therapy and the risk of developing Alzheimer's disease: the Baltimore Longitudinal Study of Aging.

Previous reports have suggested that estrogen replacement therapy (ERT) in women may exert a protective effect on their risk of developing Alzheimer's disease (AD). We investigated this relationship in the Baltimore Longitudinal Study of Aging (BLSA), a prospective multidisciplinary study of normal aging conducted by the National Institute on Aging. The sample consisted of 472 post- or perimenopausal women followed for up to 16 years in the BLSA.

The mechanisms of coenzyme Q10 as therapy for myocardial ischemia reperfusion injury.

It has been hypothesized that CoQ10 (CoQ) pretreatment protects myocardium from ischemia reperfusion (I/R) injury by its ability to increase aerobic energy production as well as its activity as an antioxidant. Isolated hearts from rats pretreated with either CoQ 20 mg/kg i.m.
