Viperin as a putative antiviral effector in rainbow trout (Oncorhynchus mykiss) cells identified by CRISPR-Cas9 functional analysis following exposure to inactivated viral hemorrhagic septicemia virus

Abstract Viperin is recognized for its potent broad-spectrum antiviral activity; however, its role in the antiviral immune response of rainbow trout ( Oncorhynchus mykiss ) remains poorly characterized. In this study, the contribution of viperin to the innate immune response agai...

Persistent influence of the North Atlantic Oscillation on Late Holocene hydroclimate in southwestern Greenland

Abstract Understanding how global climate forcing shapes regional hydroclimate on decadal to millennial timescales is critical for predicting the response of continental ice sheets to future warming. Because instrumental observations capture only a short interval, longer-term per...

Tertiary-care management of TB/HIV co-infection in Port Harcourt, Nigeria: A retrospective cohort analysis

ABSTRACT Background Monitoring the treatment of tuberculosis(TB) and human immunodeficiency virus(HIV) co-infection is very important to improve patient management and compliance. This study assessed the treatment outcomes of registered TB/HIV co-infected patients enrolled in the...

Shifting shorelines and hydroclimate changes in southern South Africa: Insights from sediment provenance during the Middle Stone Age (90-50 ka)

Southern South Africa houses some key archaeological sites, which document the behavioural and technological development of Homo sapiens . During Marine Isotope Stages (MIS) 5 and 4, this region experienced marked climate variability, particularly in temperature and precipitation...

Model 1b analytical performance specifications – report on the Prague 2025 workshop

diagnostic medical devices (IVD MD) meet regulatory and quality standards before market release; for external quality assurance assessments; for quality control, monitoring reagent lot-to-lot variability, and allowing preanalytical variation assessments in labs; and for guiding p...

Screen Use and Children’s Language Development From Ages 5 to 7 Years

Importance Concerns about screen use and early language development are widespread, and prior research has reported mixed findings. Many studies have not distinguished baseline differences from developmental change, leaving uncertainty about whether screen use is associated with...

New insights into the evolution of Charlie Chaplin worms (Histriobdellidae, Eunicida, Annelida)

Abstract Histriobdellidae, the so-called Charlie Chaplin worms, is an enigmatic group of microscopic commensal annelids associated with crustaceans. They crawl by alternately attaching their adhesive anterior appendages and left and right huge lateral ‘feet’, and bear a complex j...

Plastic polymer classification with shortwave infrared reflectance: Opportunities and limitations for remote sensing of marine debris

Marine plastic debris or litter poses urgent environmental, economic, and human health challenges, yet tools for polymer-specific detection with reflectance measurements remain limited. To advance optical classification capabilities, the newly curated and comprehensive MArine Deb...

Filtered complexes and cohomologically equivalent subcomplexes

Inspired by Rumin’s work on a subcomplex in sub-Riemannian manifolds that is cohomologically equivalent to the de Rham complex, we present a more general construction that produces subcomplexes from any filtered cochain complex of finite depth and still computes the cohomology of...

Evaluating commercial DNA extraction kits for bacterial community profiling in waterlogged archaeological wood

Understanding bacterial communities responsible for the slow biodeterioration of waterlogged archaeological wood is critical for reconstructing decay processes, predicting preservation trajectories, and informing conservation strategies. The extraction of sufficient and amplifiab...

Measuring Ocean Surface Waves

Abstract Propagating waves on the ocean surface can be represented as a stochastic process whose statistics are characterized by a spectrum. This paper reviews methods for measuring the wave spectrum and related quantities. Observations begin by sensing fluid dynamical properties...

Acceptability of Internet-Based Therapy: Considerations Expressed by Individuals Struggling with Gambling

Aims Internet-based therapy (IBT) is effective in reducing symptoms of gambling disorder (GD), yet limited acceptability may constrain treatment uptake and engagement. This study explored perspectives on the expected acceptability (defined as perceiving the intervention as approp...

7 Tesla MRI with Quantitative Susceptibility Mapping: qualitative grading and quantitative focal measurements of the substantia nigra as a potential biomarker for Parkinson’s disease

PURPOSE: Parkinson's disease (PD) is characterized by dopaminergic neuronal loss in the substantia nigra (SN). Imaging biomarkers sensitive to nigral pathology are limited. This study evaluated susceptibility changes in the SN using quantitative susceptibility mapping (QSM) and s...

Narrative review on Marburg virus disease aetiopathogenesis and management

Abstract On November 14th, 2025, the Ethiopian Ministry of Health confirmed the country’s first Marburg virus outbreak, representing another in a series of recent outbreaks across Africa in only 3 years. Marburg virus disease (MVD) is a highly lethal zoonotic haemorrhagic fever c...

The Effects of Stop Sexual Harassment: a Cluster-Randomized Controlled Trial

Abstract Sexual and gendered harassment is prevalent among adolescents and associated with health outcomes. Evidence from randomized controlled trials of school-based interventions addressing such harassment outside dating contexts among students under 16 years is limited. This s...

Acceptance of Digital Health and Well-Being: The Development of the UTAUT2-Screener

Abstract Extending conventional health and well-being services with technology has proven to be acceptable and effective. However, implementing such technology in routine care requires contextual tailoring to ensure successful uptake. The Unified Theory of Acceptance and Use of T...

Eddy kinetic energy and energy conversion rates along the Atlantic Water boundary current north of Svalbard

Abstract. On the continental slope north of Svalbard, the boundary current carrying Atlantic Water (AW) loses heat as it flows eastward. This cooling cannot be fully attributed to atmospheric heat loss or turbulent mixing. Lateral exchange, potentially linked to mesoscale activit...

The value of electronic tagging and tracking studies for understanding fish–hypoxia interactions

Abstract Objective Hypoxia (i.e., low dissolved oxygen availability) is a natural phenomenon but can also be induced by human activities (e.g., nutrient enrichment from runoff). Given that dissolved oxygen is essential for aquatic life, periods of hypoxia tend to have negative co...

Occupational Health and Safety Practices in Relation to Occupational Injuries Among Iron and Steel Workers

Occupational health and safety (OHS) malpractices may increase the risk of occupational injuries and are a significant public health problem in the iron and steel industries, often leading to disability and death. Information on OHS practices related to occupational injuries in t...

The impact of transition from paper to electronic death records on garbage codes in the Norwegian Cause of Death Registry 2018–2023

Abstract Background In 2018, electronic death certification was gradually introduced in the Norwegian Cause of Death Registry (NCoDR). Electronic certification was made mandatory from 2022. This may have affected the use and pattern of ill-defined death codes, so-called “garbage...
