Coordinated Cation Transport in TiCT MXene Membranes.

Membrane nanofiltration is an attractive strategy for the selective recovery of high-demand metals from wastewater and brine. Effective sieving of ions in aqueous environments will require precise control over membranes' nanochannel size and chemistry. TiCT MXene is an environmentally stable 2D material that can be processed into laminar membranes containing nanoscale interlayer spaces.

HEALing Communities Study: Data measures for supporting a community-based intervention to reduce opioid overdose deaths.

Introduction: The HEALing Communities Study (HCS) tested a community-based intervention in 67 communities across Kentucky, Massachusetts, New York, and Ohio to reduce opioid overdose deaths. This paper introduces the HCS measures for monitoring the intervention uptake, reports crude rates for benchmarking, and highlights the importance of interpreting jurisdictional trends in the context of state policies.

Methods: We present technical specifications for the HCS measures and the common data model.

Measures and Measurement Tools for Studying Total Worker Health.

Objective: The aim of the study was to identify survey, interview, and observational measures and measurement tools to assess constructs associated with Total Worker Health (TWH).

Methods: We conducted a scoping review to identify articles that presented or evaluated measures and tools associated with worker health, safety, and well-being. We supplemented this review with a scan of National Institute for Occupational Safety and Health's TWH website and those of the Centers of Excellence for TWH.

Impact of Asymmetric Microstructure on Ion Transport in TiCT Membranes.

Consolidation or densification of low-dimensional MXene materials into membranes can result in the formation of asymmetric membrane structures. Nanostructural (short-range) and microstructural (long-range) heterogeneity can influence mass transport and separation mechanisms. Short-range structural dynamics include the presence of water confined between the 2D layers, while long-range structural properties include the formation of defects, micropores, and mesopores.

Barriers to and facilitators for creating, disseminating, implementing, monitoring and evaluating oral health policies in the WHO African region: A scoping review.

Objective: To advance oral health policies (OHPs) in the World Health Organization (WHO) African region, barriers to and facilitators for creating, disseminating, implementing, monitoring and evaluating OHPs in the region were examined.

Methods: Global Health, Embase, PubMed, Public Affairs Information Service Index, ABI/Inform, Web of Science, Academic Search Complete, Scopus, Dissertations Global, Google Scholar, WHO's Institutional Repository for Information Sharing (IRIS), the WHO Noncommunicable Diseases Document Repository and the Regional African Index Medicus and African Journals Online were searched. Technical officers at the WHO Regional Office for Africa were contacted.

Operationalizing and selecting outcome measures for the HEALing Communities Study.

Background: The Helping to End Addiction Long-term (HEALing) Communities Study (HCS) is a multisite, parallel-group, cluster randomized wait-list controlled trial evaluating the impact of the Communities That HEAL intervention to reduce opioid overdose deaths and associated adverse outcomes. This paper presents the approach used to define and align administrative data across the four research sites to measure key study outcomes.

Methods: Priority was given to using administrative data and established data collection infrastructure to ensure reliable, timely, and sustainable measures and to harmonize study outcomes across the HCS sites.

The Modern Synthesis in the Light of Microbial Genomics.

We review the theoretical implications of findings in genomics for evolutionary biology since the Modern Synthesis. We examine the ways in which microbial genomics has influenced our understanding of the last universal common ancestor, the tree of life, species, lineages, and evolutionary transitions. We conclude by advocating a piecemeal toolkit approach to evolutionary biology, in lieu of any grand unified theory updated to include microbial genomics.

Eukaryogenesis, how special really?

Eukaryogenesis is widely viewed as an improbable evolutionary transition uniquely affecting the evolution of life on this planet. However, scientific and popular rhetoric extolling this event as a singularity lacks rigorous evidential and statistical support. Here, we question several of the usual claims about the specialness of eukaryogenesis, focusing on both eukaryogenesis as a process and its outcome, the eukaryotic cell.

A practical approach to evidence-based dentistry: How to search for evidence to inform clinical decisions.

Knowing how to search for evidence that can inform clinical decisions is a fundamental skill for the practice of evidence-based dentistry. There are many available types of evidence-based resources, characterized by their degrees of coverage of preappraised or summarized evidence at varying levels of processing, from primary studies to systematic reviews and clinical guidelines. The practice of evidence-based dentistry requires familiarity with these resources.
