Epithelial Cell Infection Analyses with Shigella.

The human-adapted enteric bacterial pathogen Shigella causes millions of infections each year, creates long-term growth effects among pediatric patients, and is a leading cause of diarrheal deaths worldwide. Infection induces watery or bloody diarrhea as a result of the pathogen transiting the gastrointestinal tract and infecting the epithelial cells lining the colon. With staggering increases in antibiotic resistance and the current lack of approved vaccines, standardized research protocols are critical to studying this formidable pathogen.

The placental exposome, placental epigenetic adaptations and lifelong cardio-metabolic health.

The placental exposome represents the sum of all placental exposures, and through its influence on placental function can affect an individual's susceptibility to cardio-metabolic disease later in life. The placental exposome includes direct exposures during gestation, as well as those prior to gestation that affect the gametes or aspects of maternal physiology that influence placental function. This review will discuss the evidence for placental responses to environmental signals and its involvement in programming offspring health.

N-acetylcysteine, xCT and suppression of Maxi-chloride channel activity in human placenta.

Introduction: Placental oxidative stress features in pregnancy pathologies but in clinical trials antioxidant supplementation has not improved outcomes. N-acetylcysteine (NAC) stimulates glutathione production and is proposed as a therapeutic agent in pregnancy. However, key elements of N-acetylcysteine biology, including its cellular uptake mechanism, remains unclear.

Vitamin D deficiency and glycemic control among patients with type 2 diabetes mellitus in Jazan City, Saudi Arabia.

The prevalence of vitamin D deficiency (VDD) is predicted to be high in patients with type 2 diabetes mellitus (T2DM), but the exact figure is not known in Jazan, Saudi Arabia. Emerging data suggests that VDD plays a role in glycemic control. The aim of this study was to measure the prevalence of VDD among T2DM patients and to investigate its association with patients' characteristics and glycemic control in Jazan.

Using simulation modelling to test the impact of future demand for end-of-life care.

Health systems globally are exploring new models of care to address the increasing demand for palliative, hospice, and end-of-life care. Yet few tools exist at the population level to explore "what if" scenarios and test, in a "cost avoidance environment," the impact of these new care models on policy, workforce, technology, and funding. This article introduces the application of scenario-based "what if" thinking and discrete event simulation in strategic planning for a not-for-profit hospice organization.
