The purpose of this study was to test the directionality of influence between reading comprehension (RC) and print exposure (PE), thereby estimating genetic and environmental effects of this relation. The sample consisted of 910 twins in fourth through ninth grades (M = 12.33 years, SD = 1.41) from the Florida Twin Project on Reading, Behavior, and Environment. Using direction-of-causation model in a twin design, results supported a direction of influence running from RC to PE. This relation was underpinned by genetic and environmental factors of RC as well as PE. Implications for reading education are discussed.

Background: The field of single cell technologies has rapidly advanced our comprehension of the human immune system, offering unprecedented insights into cellular heterogeneity and immune function. While cryopreserved peripheral blood mononuclear cell (PBMC) samples enable deep characterization of immune cells, challenges in clinical isolation and preservation limit their application in underserved communities with limited access to research facilities. We present CryoSCAPE (Cryopreservation for Scalable Cellular And Proteomic Exploration), a scalable method for immune studies of human PBMC with multi-omic single cell assays using direct cryopreservation of whole blood.

Environmental pollutants including ultrafine particulate matter (UFPs) and adverse meteorological conditions pose significant public health impacts, particularly affecting respiratory health. This study aims to elucidate the synergistic effects of cold-humid conditions and UFPs exposure on respiratory health, utilizing Carbon Black Nanoparticles (CB-NPs) as surrogates for UFPs. Through comprehensive lung function tests, histopathological examinations, and biomarker analyses, this research focuses on the modulation of oxidative stress signaling pathways and NF-κB activation.

Background: The National Institutes of Health Toolbox for Assessment of Neurological and Behavioral Function (NIHTB) was developed to address the need for a brief yet comprehensive instrument to facilitate more uniform assessment in large-scale research studies. Here, we investigated whether the cognitive measures of the NIHTB detect cognitive decline in biomarker-confirmed Alzheimer's disease (AD).
Method: We used data from N = 178 participants (age 76.

Background: Recent international work suggests that more precise subtyping within frontotemporal dementia (FTD) syndromes leads to better prediction of pathology, supporting individualized disease-specific treatments. Recent studies emphasize that identification of one such subtype, semantic behavioral variant FTD (sbvFTD), relies in part on measuring emotion recognition abilities.
Method: In order to evaluate the effectiveness of current tools, we compared the brief video-based Dynamic Affect Recognition Test (DART) against the TASIT Emotion Evaluation (EET) and Comprehensive Affect Testing System Affect Matching tests.
