Recently reported "displaceable probe" loop amplification (DP-LAMP) architecture has shown to amplify viral RNA from SARS-CoV-2 with little sample processing. The architecture allows signals indicating the presence of target nucleic acids to be spatially separated, and independent in sequence, from the complicated concatemer that LAMP processes create as part of their amplification process. This makes DP-LAMP an attractive molecular strategy to integrate with trap and sampling innovations to detect RNA from arboviruses carried by mosquitoes in the field.

HCHO at high concentrations in alkaline solutions self-reacts in the Cannizzaro reaction to give methanol and formate, neither having prebiotic value. Here, we explore the possibility that volcanic sulfur dioxide (SO) might have generated a reservoir for Hadean HCHO by a reversible reaction with HCHO to give hydroxymethanesulfonate (HMS).

The literature indicates that outcomes are improved for children and families when parents are actively involved in service provision. This article presents a literature review specific to parental engagement in child welfare services, identifies gaps in service provision, and introduces the Family-Directed Structural Assessment Tool, which addresses several challenges of engaging parents in this process.

Methods: Twelve NICUs in the Neonatal Intensive Care Quality Improvement Collaborative 2002 focused on improving neonatal pain management and sedation practices.
Objective: The objectives of this study were to review the use of oral sucrose for procedural pain management in NICUs, develop potentially better practice guidelines that are based on the best current evidence, and provide ideas for the implementation of these potentially better practices.
Methods: A collaboration of 12 centers of the Vermont Oxford Network worked together to review the strength of the evidence, clinical indications, dosage, administration, and contraindications and identify potential adverse effects for the use of sucrose analgesia as the basis of potentially better practices for sucrose analgesia guidelines. Several units implemented the guidelines.
