The objective of the present study is to determine if a brief measure of coping strategies administered to children and adolescents after a mass traumatic event - Youth Coping In Traumatic Times (YCITT) - has a factor structure similar to that of a lengthier, widely used scale, the How I Coped Under Pressure Scale (HICUPS). The YCITT was developed for the New York City - Board of Education WTC Study, conducted 6 months after 9/11. Confirmatory Factor Analyses (CFA) and Exploratory Factor Analysis (EFA) were performed in two randomly selected sub-samples of youth in grades 6-12 (sub-sample 1, n=2249; sub-sample 2, n=2315). In sub-sample 1, CFA indicated acceptable fit of a four-factor solution based on the HICUPS (distraction, active coping, support seeking and avoidance) and EFA yielded a nearly identical solution. In sub-sample 2, CFA indicated that the fit of the HICUPS-based factor solution and the solution derived from the EFA in sub-sample 1 were very similar, with both indicating acceptable model fit. In conclusion, the brief YCITT has a factor structure, which is similar to that of the HICUPS. When used in large-scale assessments of future mass traumatic events, the measure can provide relevant information about youth coping strategies across four key coping domains.

Background: While expert optometrists tend to rely on a deep understanding of the disease and intuitive pattern recognition, those with less experience may depend more on extensive data, comparisons, and external guidance. Understanding these variations is important for developing artificial intelligence (AI) systems that can effectively support optometrists with varying degrees of experience and minimize decision inconsistencies.
Objective: The main objective of this study is to identify and analyze the variations in diagnostic decision-making approaches between novice and expert optometrists.

In recent years, the theoretical description of electrical noise and fluctuation-induced effects in electrolytes has gained renewed interest, enabled by stochastic field theories like stochastic density functional theory (SDFT). Such models, however, treat solvents implicitly, ignoring their generally polar nature. In the present study, starting from microscopic principles, we derive a fully explicit SDFT theory that applies to ions in a polar solvent.

Cardiovascular disease (CVD) is the leading cause of death in the United States. Damage in the cardiovascular system can be due to environmental exposure, trauma, drug toxicity, or numerous other factors. As a result, cardiac tissue and vasculature undergo structural changes and display diminished function.

Motivation: The accurate prediction of O-GlcNAcylation sites is crucial for understanding disease mechanisms and developing effective treatments. Previous machine learning models primarily relied on primary or secondary protein structural and related properties, which have limitations in capturing the spatial interactions of neighboring amino acids. This study introduces local environmental features as a novel approach that incorporates three-dimensional spatial information, significantly improving model performance by considering the spatial context around the target site.

Secondary brain damageafter traumatic brain injury (TBI) involves oxidative stress, neuroinflammation, apoptosis, and necroptosis and can be reversed by understanding these molecular pathways. The objective of this study was to examine the impact of tasimelteon (Tasi) administration on brain injury through the nuclear factor erythroid 2-related factor 2 (NRF-2)/heme oxygenase-1 (HO-1) and receptor-interacting protein kinase 1 (RIPK1)/receptor-interacting protein kinase 3 (RIPK3)/mixed lineage kinase domain-like (MLKL) pathways in rats with TBI. Thirty-two male Wistar albino rats weighing 300-350 g were randomly divided into four groups: the control group, trauma group, Tasi-1 group (trauma + 1 mg/kg Tasi intraperitoneally), and Tasi-10 group (trauma + 10 mg/kg Tasi intraperitoneally).
