The Role of Prenatal Exposure to Lead and Manganese in Child Cognitive Neurodevelopment at 18 Months: The Results of the Italian PHIME Cohort.

Prenatal lead (Pb) and manganese (Mn) exposure can impair neurodevelopment, targeting the central nervous system. This study investigated the effects of prenatal exposure to Pb and Mn on neurodevelopment in children at 18 months of age, using data from 607 Italian mother-child pairs enrolled in the Northern Adriatic Cohort II (NAC-II). All children born at term (≥37 weeks) were assessed with the Bayley Scales of Infant and Toddler Development, third edition.

Non-dominant hand contractions do not facilitate performance under pressure in common desktop tasks.

Non-dominant hand contractions (NDHCs) have been shown to help expert motor skills in high-pressure scenarios that induce performance anxiety. Most studies of NHDCs under pressure have examined benefits in overlearned specialist movements (e.g.

Latent epigenetic programs in Müller glia contribute to stress and disease response in the retina.

Previous studies have demonstrated the dynamic changes in chromatin structure during retinal development correlate with changes in gene expression. However, those studies lack cellular resolution. Here, we integrate single-cell RNA sequencing (scRNA-seq) and single-cell assay for transposase-accessible chromatin sequencing (scATAC-seq) with bulk data to identify cell-type-specific changes in chromatin structure during human and murine development.

Initiating and Sustaining GSAs Across the District as Part of a Vision for Equity: A Case Study in Chicago Public Schools.

Background: Increasingly, there are calls for educational equity to explicitly include LGBTQ+ students, including the creation of lesbian, gay, bisexual, transgender, or queer/questioning (LGBTQ+) clubs, or Genders and Sexualities Alliances (GSAs), which are associated with positive outcomes for LGBTQ+ students and promote a safer school climate for all students. However, less is known about strategies to initiate and sustain GSAs. Chicago Public Schools (CPS) serves as a case study of how to embrace LGBTQ+ equity through an evaluation of its current practices to support GSAs.

BAD2matrix: Phylogenomic matrix concatenation, indel coding, and more.

Premise: Common steps in phylogenomic matrix production include biological sequence concatenation, morphological data concatenation, insertion/deletion (indel) coding, gene content (presence/absence) coding, removing uninformative characters for parsimony analysis, recording with reduced amino acid alphabets, and occupancy filtering. Existing software does not accomplish these tasks on a phylogenomic scale using a single program.

Methods And Results: BAD2matrix is a Python script that performs the above-mentioned steps in phylogenomic matrix construction for DNA or amino acid sequences as well as morphological data.
