A critical qualitative study to understand current black women medical student perspectives on anti-racist reform in US medical education.

Purpose: The US medical education system has a long-standing history of omitting evidence and perpetuating false pseudo-scientific beliefs on the complex and nuanced relationships between race, racism, and health disparities. There is an urgent need to identify and address the historical influence of systemic racism on the current curriculum, organization, and culture of US medical education. The goal of this study was to understand Black women medical student perspectives on race and racism in current medical school training and their recommendations to inform anti-racist action in US medical education.

Chimeric mutants of staphylococcal hemolysin, which act as both one-component and two-component hemolysin, created by grafting the stem domain.

Staphylococcus aureus expresses several hemolytic pore-forming toxins (PFTs), which are all commonly composed of three domains: cap, rim and stem. PFTs are expressed as soluble monomers and assemble to form a transmembrane β-barrel pore in the erythrocyte cell membrane. The stem domain undergoes dramatic conformational changes to form a pore.

The effect of violence in childhood on school success factors in US children.

Background: A robust literature-base on adverse childhood experiences (ACEs) provides strong evidence on the relationships between social adversity in childhood and the health and well-being of individuals across the lifespan. One form of social adversity, exposure to violence in childhood, is not only harmful to a child's health and well-being, but detrimental to their performance in school. Poor performance in school may affect educational attainment later in life and hinder a child's upward social mobility.

Provider Experiences with a Payer-Based PCMH Program.

Background: The patient-centered medical home (PCMH) is an enhanced primary care model that aims to improve quality of care. Over the past several years, the PCMH model has been adopted by Medicare and private payers, which offer financial resources and technical assistance to participating practices. However, few studies have examined provider experiences and perspectives on the adoption of payer-based PCMH models in different practice settings.

SDS-induced oligomerization of Lys49-phospholipase A from snake venom.

Phospholipase A (PLA) is one of the representative toxic components of snake venom. PLAs are categorized into several subgroups according to the amino acid at position 49, which comprises either Asp49, Lys49, Arg49 or Ser49. Previous studies suggested that the Lys49-PLA assembles into an extremely stable dimer.
