Ectromelia Virus Reprograms the Noncanonical NF-κB Signaling Pathway in HeLa Epithelial Cells

Abstract The noncanonical nuclear factor κB (NF-κB) pathway regulates adaptive immune responses and antiviral innate immunity. Orthopoxviruses, including the human pathogen variola virus and zoonotic viruses such as vaccinia virus and monkeypox virus, have evolved multiple strate...

Becoming Through Doing: Lived Experiences and Professional Identity Development in Marketing Students’ Industrial Placements

This study explores the lived experiences of marketing students during year-long industrial placements (a.k.a. internships), focusing on how these experiences contribute to professional identity development. Although industrial placements are widely recognized for enhancing stude...

Observation of a supersolid phase in a spin-orbit coupled exciton-polariton Bose-Einstein condensate

In Bose-Einstein condensates, spin-orbit coupling (SOC) produces supersolidity. It is a peculiar state of matter, which, in addition to the superfluid behavior, shows periodic density modulation typical for crystals. Here, we report the fabrication of an original type of optical...

Pain Coping Strategies Among Adult Patients with Degenerative Disc Disease

Background/Objectives: This cross-sectional observational study aimed to investigate how individuals with lumbar degenerative disc disease (DDD) cope with pain and its association with their affective state, especially in relation to the symptoms of anxiety and depression. The st...

Block vote, open-list proportional representation, and women’s electoral outcomes. Evidence from a quasi-experiment in Polish local elections

Although pioneering research suggested that proportional elections are better for women’s outcomes than plurality rules, research scholarship is accumulating growing evidence that this relationship depends on specific rules. We look at the impact of electoral rules on female part...

Hominin behavior, strategies, and environmental conditions in Southern Europe (Marine Isotope Stage 17–15): The 100-ka sequence of Notarchirico (Italy, 700–600 ka)

The Notarchirico sequence comprises a continuous 100-ka-long record of phases of hominin occupation between Marine Isotope Stage 17 and Marine Isotope Stage 15, revealing remarkable technological stability alongside some innovations. We analyzed core technology, raw material prov...

Economic impacts of subsea cable deployment

This paper provides a comprehensive empirical analysis of the economic impact of submarine cable (SMC) infrastructure, which is critical for global digital connectivity and carries almost all intercontinental data traffic. Despite their fundamental role in the digital economy, ro...

Efficient Quasi-Resonant, Polarization-Selective Excitation of GaN Quantum Emitters

Abstract Defect centers in gallium nitride (GaN) emerge as bright sources of single photons, which recently have been demonstrated to optically interface a localized spin. However, the structure and composition of these defects as well as their efficient excitation techniques hav...

Sub-kJ/mol Precision at Practical Cost for Molecular Solids through Local Coupled-Cluster Approaches

Abstract Generation of numerically converged coupled-cluster reference energies of molecular crystals remains highly non-routine. Yet, such data points are critically needed as computational methodologies strive to reach correlated wave-function accuracy in condensed-phase system...

Structure and Solvent Trapping in Polymer Brushes Under Poor-Solvent Conditions

Polymer brushes exhibit complex structural responses to changes in grafting density and solvent quality, particularly under poor-solvent conditions. Although brush collapse has been extensively studied, the role of an explicit solvent in determining the structure and conformation...

Odonates (Odonata) as indicators of the natural potential of sand mine ponds (Central Europe): environmental drivers and implications for biodiversity conservation

Odonates (dragonflies and damselflies) are well-recognized indicators of freshwater ecosystems; therefore, they were used to describe the natural potential of man-made habitats, i.e. sand ponds, in terms of species, ecological patterns of the occurrence of both larval and adult a...

Ethno‐National and Religious Identifications, Identity Compatibility, and Trust in Leaders: A Two‐Study Investigation in a Politically Fragmented Society

ABSTRACT Social identities, such as ethno‐national and religious identities, can shape group cohesion, trust in leadership, and societal stability in politically fragmented contexts. A key factor influencing these dynamics is identity compatibility—the extent to which individuals...

Mass Spectrometry-Based Omics: An Integrated Framework for Analytical Quality, Data Integrity, and Biological Interpretation

Results obtained with mass spectrometry-based omics depend on every stage of the work, from sample collection to data processing. Quality guidance exists for individual omics fields and for individual stages, but it rarely states when a dataset is ready for statistical analysis o...

Diversity and distribution of ticks collected from vegetation and domestic animals in Zambia

Ticks are major vectors of pathogens affecting livestock and human health in sub-Saharan Africa, yet integrated data on tick diversity across ecological gradients remain limited. In Zambia, most studies have focused on livestock-associated ticks, with little emphasis on compariso...

Food-Grade By-Products as Sustainable Sources of Phytochemicals: Green Extraction Strategies, Encapsulation Technologies, and Applications in Functional Food Development

Food-industry by-products, including fruit and vegetable pomace, peels, and seeds, are increasingly recognized as sustainable sources of bioactive compounds, particularly phenolic compounds and carotenoids, including anthocyanins and lycopene. These phytochemicals exhibit a range...

From generic to salutogenic urbanism: Evidence of the landmark paradox and the role of biodiversity and walkability in mental health

Public place walkability is central to health-oriented urban planning. Facing a global polycrisis (climate, mental health, physical activity, and biodiversity challenges) salutogenic environmental research is crucial for cross-sector recommendations. Yet, evidence integrating psy...

CD146 + cell engraftment improves vascularization, and impact tissue remodelling in dystrophic skeletal muscle of mdx mice

CD146 + cells have been described as myogenic progenitors residing in the interstitial space of skeletal muscle in both mice and humans. Previous studies demonstrated that intramuscular transplantation of CD146 + cells can enhance regeneration of injured or immobilized skeletal m...

Pharmacological targeting of ferroptosis in cancer: mechanisms, tumor immunity, and translational challenges

Abstract Ferroptosis is an iron-dependent form of regulated cell death driven by phospholipid peroxidation and the failure of cellular antioxidant defenses. Its close integration with iron metabolism, lipid remodeling, and redox homeostasis has identified ferroptosis as a potenti...

LUXE: a high-precision experiment to study non-perturbative QED in electron–laser and photon–laser collisions

Abstract The Laser Und XFEL Experiment (LUXE), in planning at DESY Hamburg, is intended to study quantum electrodynamics (QED) in strong electromagnetic fields and in particular the transition from the perturbative to the non-perturbative domain. In the non-perturbative regime, e...

Miseeda: between kingdoms, through epochs—reconstructing a history of the Mahas region (Sudan)

The Good Shepherd of Miseeda project investigates remains in a section of the Mahas region in northern Sudan. Centred on a church built around an ancient petroglyph, integrated archaeological survey and ethnographic research trace millennia of cultural interaction, continuity and...
