Transglutaminase 2 contributes to the blood clotting cascade

Abstract Cross-linking of fibrin and associated proteins via Nε-(γ-glutamyl)lysine bonds in clot formation is a well-established component of the hemodynamic mechanism, providing clot rigidity and reducing the rate of fibrinolysis. The latter effect occurs predominantly through t...

Gender inclusive language in healthcare professionals’ education: a scoping review

Abstract Background Lesbian, Gay, Bisexual, Transgender and Queer (LGBTQ+) individuals experience unique healthcare challenges, with disparities exacerbated by the use of non-inclusive or stigmatising language. Healthcare professionals’ education plays a critical role in fosterin...

Advancing hydraulic conductivity estimation in the Permo-Triassic Sherwood Sandstone Group using borehole NMR logging

Abstract The Permo-Triassic Sherwood Sandstone Group is an important aquifer in the United Kingdom (UK) for groundwater and geothermal energy applications. Hydraulic conductivity ( K ) is essential for understanding groundwater movement, contaminant and heat transport in aquifers...

Audit and feedback interventions for recruitment and retention in clinical trials: A systematic review

BACKGROUND/AIMS: This study had two objectives: (1) to determine the effectiveness of audit and feedback interventions for improving recruitment and retention in randomised controlled trials (hereinafter referred to as trials) and (2) to identify and code behaviour change techniq...

Green surveillance: the social implications of harnessing local communities for conservation law enforcement in Namibia

In response to the social injustice and counterproductivity attributed to militarised conservation, anti-poaching efforts increasingly focus on ‘inclusivity’ and surveillance. This shift can be explained with the emergence of ontopower, a new form of environmental power that focu...

Brain iron as a surrogate biomarker of pathological TDP-43 identifies brain region-specific signatures in aging, and disease

Abstract Background TDP-43 pathology is a defining feature of several neurodegenerative diseases, but its prevalence and regional distribution in aging and disease are not well characterised. We investigated molecular TDP-43 dysregulation across aging, Alzheimer’s disease (AD), a...

EXPRESS: Dissociating attentional and working memory load in memory for emotional faces

There is evidence that both general attention load and face-specific working memory load modulate the processing of emotional faces, but the contribution of each remains uncertain. Here, we investigated how these resources modulate the recognition of emotional faces in working me...

Grassland soil bulk density decreases under grazing exclusion and responds asymmetrically to altered precipitation

Soil structure is a key determinant of grassland health and functioning, with bulk density serving as a widely used proxy. Grazing exclusion is a common restoration practice that often reduces soil bulk density in grasslands by restoring plant productivity and removing livestock...

Why Some Gestures Work Better than Others: Toward a Model of Gesture-Supported Vocabulary Learning

Abstract Gesture has emerged as a powerful multimodal tool in vocabulary acquisition, with converging behavioral and neuroscientific evidence for its facilitative role in second language (L2) vocabulary learning. Yet in both instructional practice and experimental research, gestu...

Enabling climate action: A nexus approach for delivering co-benefits across biodiversity, water, food, and health

Climate response options rarely affect biodiversity, water, food, and health in uniform ways. This comparative analysis examines why technically viable response options generate uneven cross-nexus outcomes, and how governance and justice conditions shape whether these outcomes be...

Calcium Isotopic Composition in Reindeer ( Rangifer tarandus ) Bones and Tooth Enamel: A Scalable Tool to Quantify Nursing Frequency in Past and Modern Populations?

RATIONALE: Populations of North American caribou and Eurasian reindeer (Rangifer tarandus sspp.), essential for Arctic ecosystems and human communities, are experiencing unprecedented declines due to climate change and anthropogenic pressures. While understanding their historical...

Implementation mapping, research capacity building and reflexivity: a case study on how to select implementation strategies to increase reach of HPV vaccination in Zambia

Human papillomavirus (HPV) vaccination is effective in preventing most cervical cancer, but coverage is low in Zambia. In this methods paper, we describe how we adapted implementation mapping to select and develop implementation strategies for HPV vaccination delivery by embeddin...

A major monastic centre? Rethinking Lismore’s place in the ecclesiastical landscapes of early medieval Britain

Until recent decades, the monastery of Lios Mòr (Lismore) in Argyll, Scotland, established by Saint Mo Luóc in the sixth century, was attested only via historical references and local traditions. Community-led investigations have now revealed an early medieval cemetery, sophistic...

MEGATRON: Reproducing the Diversity of High-Redshift Galaxy Spectra with Cosmological Radiation Hydrodynamics Simulations

We present the MEGATRON suite of cosmological radiation hydrodynamics simulations following the formation of Milky Way-mass galaxies from the earliest cosmic epochs when Population III stars form to Cosmic Noon. The suite represents the first set of cosmological simulations that...

Impact of a Mediterranean diet and physical activity intervention on the gut microbiome and faecal metabolites: findings from the MedEx-UK randomised controlled trial

Abstract Diet and physical activity (PA) are potential modulators of the gut microbiome, although research findings are inconsistent, and few studies have explored their combined effects. This study used data from ninety-three participants (forty-seven with pre- and post-interven...

Anomalous Transport in the Fermi-Pasta-Ulam-Tsingou Model: A Review and Open Problems

Abstract This review provides an up-to-date account of energy transport in Fermi-Pasta-Ulam-Tsingou (FPUT) chains, a key testbed for nonequilibrium statistical physics. We discuss the transition from the historical puzzle of thermalization to the discovery of anomalous heat trans...

MEGATRON: how the first stars can create an iron metallicity plateau in the smallest dwarf galaxies

We study the stellar mass-iron metallicity relation of dwarf galaxies in the new high-resolution MEGATRON cosmological radiation-hydrodynamics simulations. These simulations model galaxy formation up to z ≈ 8 in a region that will collapse into a Milky-Way-like galaxy at z = 0 ,...

MEGATRON: the impact of non-equilibrium effects and local radiation fields on the circumgalactic medium at cosmic noon

We present three cosmological radiation-hydrodynamic zoom simulations of the progenitor of a Milky Way-mass galaxy from the MEGATRON suite. The simulations combine on-the-fly radiative transfer with a detailed non-equilibrium thermochemical network (81 ions and molecules), resolv...

Articular presentation of Mycobacterium avium ssp. avium infection in a golden eagle ( Aquila chrysaetos ) on the Isle of Lewis, Scotland

Summary A wild golden eagle ( Aquila chrysaetos) was found dead in poor body condition. On gross examination, the bird was emaciated, with damaged feathers and an enlarged right tibiofemoral joint due to multiple pale, smooth, nodular and plaque‐like masses. High numbers of acid‐...

Hot-springs through time, and how to find them

Hot-springs have fascinated geologists including James Hutton for centuries. Here we synthesise data collected over timescales from centuries to days to reveal rules governing hot-springs, including where and when they occur. Data reveal waters dominantly sourced from the surface...
