Disentangling the temporal relationship between alcohol-related attitudes and heavy episodic drinking in adolescents within a randomized controlled trial.

Background And Aims: Within many alcohol prevention interventions, changes in alcohol-related attitudes (ARA) are often proposed as precursors to changes in drinking behaviour. This study aimed to measure the longitudinal relationship between ARA and behaviour during the implementation of a large-scale prevention trial.

Design And Setting: This study was a two-arm school-based clustered randomized controlled trial.

Suspended Tissue Open Microfluidic Patterning (STOMP).

Cell-laden hydrogel constructs suspended between pillars are powerful tools for modeling tissue structure and physiology, though current fabrication techniques often limit them to uniform compositions. In contrast, tissues are complex in nature with spatial arrangements of cell types and extracellular matrices. Thus, we present Suspended Tissue Open Microfluidic Patterning (STOMP), which utilizes a removable, open microfluidic patterning channel to pattern multiple spatial regions across a single suspended tissue.

Engineered Heart Tissues for Standard 96-Well Tissue Culture Plates.

Engineered heart tissues (EHTs) have been shown to be a valuable platform for disease investigation and therapeutic testing by increasing human induced pluripotent stem cell-derived cardiomyocyte (hiPSC-CM) maturity and better recreating the native cardiac environment. The protocol detailed in this chapter describes the generation of miniaturized EHTs (mEHTs) incorporating hiPSC-CMs and human stromal cells in a fibrin hydrogel. This platform utilizes an array of silicone posts designed to fit in a standard 96-well tissue culture plate.

Targeted CRISPR activation is functional in engineered human pluripotent stem cells but undergoes silencing after differentiation into cardiomyocytes and endothelium.

Human induced pluripotent stem cells (hiPSCs) offer opportunities to study human biology where primary cell types are limited. CRISPR technology allows forward genetic screens using engineered Cas9-expressing cells. Here, we sought to generate a CRISPR activation (CRISPRa) hiPSC line to activate endogenous genes during pluripotency and differentiation.

Reliability and Validity of a Multidimensional Measure of Subjective Community Well-Being.

An individual's flourishing is sustained by and dependent on their community's well-being. We provide one of the first studies of a measure of communal subjective well-being, focusing on individuals' relationships with their community. Using two samples from the Greater Columbus, Ohio region, we provide evidence of the reliability and validity of the Subjective Community Well-being (SCWB) assessment.
