Integration of QSAR and NAM in the Read-Across Process for an Effective and Relevant Toxicological Assessment.

Read-Across (RAx) serves as a strategy to fill a data gap in the toxicological profile of a substance (target) using existing information on similar source substances. The principle is applied also to a category of substances for which similarity may follow a regular trend. Demonstration of similarity is not trivial and requires the analysis of different steps, starting from the precise analytical characterization of both target and source substances and including the analysis of the impact that each minor difference can have on the final outcome.

Relating gut microbiome composition and life history metrics for pronghorn (Antilocapra americana) in the Red Desert, Wyoming.

Host microbial communities (hereafter, the 'microbiome') are recognized as an important aspect of host health and are gaining attention as a useful biomarker to understand the ecology and demographics of wildlife populations. Several studies indicate that the microbiome may contribute to the adaptive capacity of animals to changing environments associated with increasing habitat fragmentation and rapid climate change. To this end, we investigated the gut microbiome of pronghorn (Antilocapra americana), an iconic species in an environment that is undergoing both climatic and anthropogenic change.

Temporary establishment of bacteria from indoor plant leaves and soil on human skin.

Background: Plants are found in a large percentage of indoor environments, yet the potential for bacteria associated with indoor plant leaves and soil to colonize human skin remains unclear. We report results of experiments in a controlled climate chamber to characterize bacterial communities inhabiting the substrates and leaves of five indoor plant species, and quantify microbial transfer dynamics and residence times on human skin following simulated touch contact events. Controlled bacterial propagule transfer events with soil and leaf donors were applied to the arms of human occupants and repeatedly measured over a 24-h period using 16S rRNA gene amplicon sequencing.

Effect of dialysate bicarbonate and sodium on blood pH in maintenance hemodialysis-A prospective study.

Introduction: The validity of adjusting dialysate bicarbonate based on pre-hemodialysis (HD) serum bicarbonate is unclear. There are no studies of the impact of dialysate sodium on blood pH.

Aims: To understand the impact of dialysate bicarbonate and sodium on blood pH.

Creation of an Electronic Resource Repository for Differences of Sex Development (DSD): Collaboration Between Advocates and Clinicians in the DSD-Translational Research Network.

Introduction: People with differences of sex development (DSD) and their families need education about these conditions while receiving emotional and peer support to participate in shared decision-making, reduce social isolation, and optimize physical and psychosocial outcomes. Barriers to education and support include limited knowledge and awareness by healthcare providers, tension among patient and medical communities, varied quality of educational resources, and the sensitive nature of DSD. We aimed to create an electronic repository of vetted quality online resources about DSD.
