Despite , prejudice still exists in the American school system. These attitudes can give rise to negative social experiences for students of color (i.e., discrimination), negatively impacting their mental and physical health and creating disparities in educational outcomes. Rather than seeking to ameliorate these negative experiences, our approach attempts to address the underlying prejudices and, in so doing, reduce these disparities. Using 4 waves of data from a cluster randomized trial ( = 15 middle schools, 1,890 students, 47.1% female, 75.2% White), we hypothesized that cooperative learning, which has been shown to reduce prejudice in previous research, would create positive gains in peer relatedness, perceptions of academic support, and engagement in learning, and that gains would be larger for students of color; our results confirmed these hypotheses. Our findings highlight the potential role of cooperative learning in reducing disparities and creating greater equity in education.

Despite extensive mapping of cis-regulatory elements (cREs) across cellular contexts with chromatin accessibility assays, the sequence syntax and genetic variants that regulate transcription factor (TF) binding and chromatin accessibility at context-specific cREs remain elusive. We introduce ChromBPNet, a deep learning DNA sequence model of base-resolution accessibility profiles that detects, learns and deconvolves assay-specific enzyme biases from regulatory sequence determinants of accessibility, enabling robust discovery of compact TF motif lexicons, cooperative motif syntax and precision footprints across assays and sequencing depths. Extensive benchmarks show that ChromBPNet, despite its lightweight design, is competitive with much larger contemporary models at predicting variant effects on chromatin accessibility, pioneer TF binding and reporter activity across assays, cell contexts and ancestry, while providing interpretation of disrupted regulatory syntax.

Background: Healthy Actions and Lifestyles to Avoid Dementia Program (HALT-AD) or Hispanos y el ALTo a la Demencia is a recently-developed online educational platform to help individuals identify and modify their own dementia modifiable risk factors (MRF). In light of known challenges in recruiting and retaining diverse participants in research studies, there is a need to identify data-informed strategies that will contribute to effective outreach and tailored implementation of HALT-AD among its intended users of Hispanic and non-Hispanic midlife and older adults in the US.
Objectives: To identify factors (i.

On occasion of the DNT5 meeting in Konstanz, Germany (April-2024), participants brainstormed on future challenges concerning a regulatory implementation of the developmental neurotoxicity (DNT) in vitro test battery (DNT-IVB). The five discussion topics below outline some of the key issues, opportunities and research directions for the next several years: (1) How to contextualize DNT hazard with information on potential maternal toxicity or other toxicity domains (non-DNT)? Several approaches on how to use cytotoxicity data from NAMs were discussed. (2) What opportunities exist for an immediate or near-future application of the DNT-IVB, e.

Interprofessional teaching rounds are a practical application of interprofessional education in bedside teaching, yet there is a lack of research on how interprofessional teaching rounds should be implemented into medical education. This study aimed to describe our experience in developing and implementing interprofessional teaching rounds during a clerkship rotation for medical students, and compares its strengths and weaknesses relative to traditional teaching rounds. Medical students were assigned to either the interprofessional teaching round group ( = 24) or the traditional teaching round group ( = 25), and each group participated in their assigned type of teaching round.

Chronic fluorosis is often accompanied by neurological symptoms, leading to attention, memory and learning ability decline and causing tension, anxiety, depression, and other mental symptoms. In the present study, we analyzed the molecular mechanisms of SIRT1-BDNF regulation of PI3K-AKT, MAPK, and FOXO1A in F-treated BV2 cells. The cytotoxic effect of sodium fluoride (NaF) on BV2 cells was assessed using Cell Counting Kit-8 (CCK-8), crystal violet, and 5-ethynyl-2'-deoxyuridine (EdU) staining.
