Helioseismic inference of the solar radiative opacity.

The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current debate on its chemical composition. The problem reaches far beyond chemical abundances and is intimately linked to microscopic and macroscopic physical ingredients of solar models such as radiative opacity, for which experimental results have been recently measured that still await theoretical explanations.

Resilience resources among African American women living with HIV in Southern United States.

Objectives: African American women living with HIV (WLH) often face various challenges to access to and benefit from healthcare across the HIV treatment cascade. Despite experiencing multiple forms of ongoing adversity, some African American WLH are able to adapt and stand strong. The current study aims to identify resources at various socioecological levels that facilitate resilience and explore how these resources interact with each other.

The Inner Working of Trauma: A Qualitative Assessment of Experiences of Trauma, Intergenerational Family Dynamics, and Psychological Well-Being in Women With HIV in South Carolina.

Women with HIV are more likely to have a history of traumatic and stressful life experiences. The current study examines experiences of traumatic and stressful life events, issues co-occurring with experiences of trauma, and intergenerational family dynamics regarding trauma and psychological well-being in women with HIV. The study was guided by the theoretical approach of an integrative translational model that incorporates trauma-related factors into a psychosocial framework.

Antipsychotics for aggression in adults: A meta-analysis.

Aggressive behavior complicates the presentation of many psychiatric illnesses, and is associated with significant morbidity. Antipsychotic medications are used to treat this symptom dimension across multiple diagnoses. In this meta-analysis we sought to identify the effect size of antipsychotic medications for the treatment of reactive-impulsive aggression in adults, and identify differences across underlying diagnosis and specific agent.

Deletion of liaR Reverses Daptomycin Resistance in Enterococcus faecium Independent of the Genetic Background.

We have shown previously that changes in LiaFSR, a three-component regulatory system predicted to orchestrate the cell membrane stress response, are important mediators of daptomycin (DAP) resistance in enterococci. Indeed, deletion of the gene encoding the response regulator LiaR in a clinical strain of Enterococcus faecalis reversed DAP resistance (DAP-R) and produced a strain hypersusceptible to antimicrobial peptides. Since LiaFSR is conserved in Enterococcus faecium, we investigated the role of LiaR in a variety of clinical E.
