Oxygen controls most metazoan metabolism, yet in mammals, tissue O levels vary widely. While extensive research has explored cellular responses to hypoxia, understanding how cells respond to physiologically high O levels remains uncertain. To address this problem, we investigated respiratory epithelia as their contact with air exposes them to some of the highest O levels in the body.

Oxidative stress in critically ill neonatal foals.

J Vet Intern Med

January 2025

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Iowa State University, Ames, Iowa, USA.

Background: Oxidative injury occurs in septic people, but the role of oxidative stress and antioxidants has rarely been evaluated in foals.

Objectives/hypothesis: To measure reactive oxygen species (ROS), biomarkers of oxidative injury, and antioxidants in neonatal foals. We hypothesized that ill foals would have higher blood concentrations of ROS and biomarkers of oxidative injury and lower concentrations of antioxidants compared to healthy foals.

The partitioning of photosynthate among various forest carbon pools is a key process regulating long-term carbon sequestration, with allocation to aboveground woody biomass carbon (AGBC) in particular playing an outsized role in the global carbon cycle due to its slow residence time. However, directly estimating the fraction of gross primary productivity (GPP) that goes to AGBC has historically been difficult and time-consuming, leaving us with persistent uncertainties. We used an extensive dataset of tree-ring chronologies co-located at flux towers to assess the coupling between AGBC and GPP, calculate the fraction of fixed carbon that is allocated to AGBC, and understand the drivers of variability in this fraction.

We examined the relationship between socioeconomic status (SES) and endorsement of honour. We studied the SES-honour link in 5 studies (N = 13,635) with participants recruited in different world regions (the Mediterranean and MENA, East Asian, South-East Asian, and Anglo-Western regions) using measures that tap into various different facets of honour. Findings from these studies revealed that individuals who subjectively perceived themselves as belonging to a higher (vs.

A new proliferation of optical instruments that can be attached to towers over or within ecosystems, or 'proximal' remote sensing, enables a comprehensive characterization of terrestrial ecosystem structure, function, and fluxes of energy, water, and carbon. Proximal remote sensing can bridge the gap between individual plants, site-level eddy-covariance fluxes, and airborne and spaceborne remote sensing by providing continuous data at a high-spatiotemporal resolution. Here, we review recent advances in proximal remote sensing for improving our mechanistic understanding of plant and ecosystem processes, model development, and validation of current and upcoming satellite missions.

Cocaine use disorder (CUD) is associated with executive functioning impairments linked to serotonergic function. Previous studies reported efficacy with the selective serotonin reuptake inhibitor citalopram in reducing cocaine use. The current study explored moderation and mediation of citalopram effects on cocaine use by performance across executive function domains.

Maize is one of the major crops that are susceptible to infection and subsequent aflatoxin contamination, which poses a serious health threat to humans and domestic animals. Here, an RNA interference (RNAi) approach called Host-Induced Gene Silencing (HIGS) was employed to suppress the -methyl transferase gene (, also called ), a key gene involved in aflatoxin biosynthesis. An RNAi vector carrying part of the gene was introduced into the B104 maize line.

Population-based sampling has improved pathogen monitoring in the US swine industry by increasing sensitivity while reducing costs. Postmortem tongue fluids (TF) have emerged as a practical option for monitoring porcine reproductive and respiratory syndrome virus (PRRSV) in breeding herds, but limited data exist on optimal storage conditions. This study evaluated PRRSV RNA detection via RT-qPCR in TF samples under various storage times, temperatures, and viral loads.

Wear Resistance of Light-Cure Resin Luting Cements for Ceramic Veneers.

J Funct Biomater

December 2024

Department of Operative Dentistry, School of Dentistry, Aichi Gakuin University, Nagoya 464-8651, Japan.

The purpose of this study was to compare the wear resistance of light-cure resin luting cements for veneers with that of other luting materials investigated in earlier studies. An Alabama wear-testing machine was used to measure the wear resistance of four recent light-cure resin luting cements for veneers (G-Cem Veneer; Panavia V5 LC; RelyX Veneer Cement; and Vario-link Esthetic LC). The volume loss ranged from 0.

Inadmissible evidence generally biases jurors toward guilty verdicts; jurors who hear inadmissible evidence are more likely to convict than jurors not exposed to inadmissible evidence-even when evidence is constant. When inadmissible evidence is introduced, the common legal remedy is judicial instructions to jurors to disregard it. Appeals courts repeatedly affirm instructions to disregard as a sufficient safeguard of defendants' constitutional rights, despite research finding that jurors do not disregard when instructed.

Background/objectives: Cognitive functions are a crucial part of daily living, especially for adults with Down syndrome (DS) who have a high likelihood of developing Alzheimer's disease in adulthood. In addition, adults with DS move slower and are not meeting the standard aerobic activity guidelines each week. The aim of this study was to examine if Assisted Cycle Therapy (ACT) would improve cognitive planning as measured by the Tower of London (TOL), set switching as measured by the modified Wisconsin Card Sorting Test, and spatial memory as measured by the Corsi Block Test in adults with DS as compared to self-paced cycling.

To reduce chronic school absenteeism and morbidity and mortality among school-aged children, the prompt administration of albuterol sulfate in schools remains vital. School-based stock inhaler programs are a practical approach to ensure equitable access to life-saving rescue medication for students. School and community partnerships can potentially strengthen program implementation and fidelity by integrating evidence-based practices into routine care.

Background: Children from racial and ethnic minority groups are at greater risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but it is unclear whether they have increased risk for post-acute sequelae of SARS-CoV-2 (PASC). Our objectives were to assess whether the risk of respiratory and neurologic PASC differs by race/ethnicity and social drivers of health.

Methods: We conducted a retrospective cohort study of individuals <21 years seeking care at 24 health systems across the U.

Introduction: Mental health issues disproportionately affect rural and low-income populations, where access to prevention and treatment is limited. Implementing telemental health services (TMHS) in Federally Qualified Health Centers (FQHCs) could improve accessibility to mental healthcare. This study assessed the effect of TMHS on mental health services utilization in FQHCs, comparing centers with and without TMHS and examined differences in TMHS effect between FQHCs that adopted TMHS before and during the pandemic.

Cost-benefit tradeoff mediates the transition from rule-based to memory-based processing during practice.

PLoS Biol

January 2025

Cognitive Control Collaborative, University of Iowa, Iowa City, Iowa, United States of America.

Practice not only improves task performance but also changes task execution from rule- to memory-based processing by incorporating experiences from practice. However, how and when this change occurs is unclear. We test the hypothesis that strategy transitions in task learning can result from decision-making guided by cost-benefit analysis.
