Integrating opinion dynamics and differential game modeling for sustainable groundwater management.

Water Res

September 2025

College of Hydrology and Water Resources, Hohai University, Nanjing 210098, China. Electronic address:

Groundwater overextraction presents persistent challenges due to strategic interdependence among decentralized users. While game-theoretic models have advanced the analysis of individual incentives and collective outcomes, most frameworks assume fully rational agents and neglect the role of cognitive and social factors. This study proposes a coupled model that integrates opinion dynamics with a differential game of groundwater extraction, capturing the interaction between institutional authority and evolving stakeholder preferences.

Gene dysregulation impairs placental angiogenesis in allogeneic pig pregnancies.

Anim Reprod Sci

September 2025

Department of Biomedical & Clinical Sciences (BKV), BKH/Obstetrics & Gynecology, Faculty of Medicine and Health Sciences, Linköping University, Linköping SE-58185, Sweden.

Embryo transfer (ET) is a valuable reproductive technology in pigs, albeit its efficiency remains significantly lower than that of natural mating or artificial insemination (AI), owing to high embryonic death rates. Critical for embryo survival and pregnancy success is the placenta, which supports conceptus development through nutrient exchange, hormone production, and immune modulation. Alterations in placental development and function may therefore underlie the reduced efficiency of ET.

Transcutaneous devices such as dental implants frequently fail due to infections at their interfaces with epithelial tissues. These infections are facilitated by the lack of integration between the devices and the surrounding soft tissues. This study aims to improve epithelial integration through surface modification of a transcutaneous implant material (polyetheretherketone (PEEK)).

Zanubrutinib is a next-generation covalent Bruton tyrosine kinase (BTK) inhibitor designed to provide complete and sustained BTK occupancy for efficacy across disease-relevant tissues, with fewer off-target adverse events (AEs) than other covalent BTK inhibitors. In the phase 3 ASPEN study (BGB-3111-302), comparable efficacy and a favorable safety profile versus ibrutinib were demonstrated in patients with MYD88-mutated Waldenström macroglobulinemia (WM), leading to approval of zanubrutinib for patients with WM. BGB-3111-LTE1 (LTE1) is a long-term extension study to which eligible patients, including patients from comparator treatment arms, could enroll following participation in various parent studies of zanubrutinib to treat B-cell malignancies.

Background And Aims: Crop wild relatives (CWRs) are key resources for enhancing agricultural resilience, providing genetic traits that can improve pest resistance, abiotic stress tolerance, and nutritional composition in domesticated crops. Within the mustard family (Brassicaceae) this is especially significant in the Brassiceae tribe, which includes economically important genera for agriculture such as Brassica and Sinapis. However, while breeding programmes have historically focused on major crops within this tribe, the potential of their wild relatives, particularly for underutilised and minor crops, remains insufficiently explored.

Background: The clinical course and outcomes of alcohol-associated hepatitis (AH) remain poorly understood. Major adverse liver outcomes (MALO) do not capture the added risk of return to drinking (RTD). We examined the natural history of AH and developed a composite endpoint using a contemporary observational cohort of AH.

Background: Stroke is a leading cause of death and disability globally, with frequent cognitive sequelae affecting up to 60% of stroke survivors. Despite the high prevalence of post-stroke cognitive impairment (PSCI), early detection remains underemphasized in clinical practice, with limited focus on broader neuropsychological and affective symptoms. Stroke elevates dementia risk and may act as a trigger for progressive neurodegenerative diseases.

Uropathogenic Escherichia coli (UPEC) are among the first pathogens to colonise in catheter and non-catheter-associated urinary tract infections. However, these infections are often polymicrobial, resulting in multi-species infections that persist by forming biofilms. Living within these highly antimicrobial tolerant communities, bacteria can establish intra- and inter-specific interactions, including quorum sensing (QS)-mediated signalling mechanisms, which play a key role in biofilm establishment and maturation.

Essentials of the System of Radiological Protection.

J Radiol Prot

September 2025

Centre for Radiation Protection Research, Stockholm University, Svante Arrheniusväg 20C, 106 91 Stockholm, Sweden.

The System of Radiological Protection (the "System") developed by the International Commission on Radiological Protection (ICRP) is built on nearly a century of efforts of numerous scientists and practitioners working together internationally. It rests on three enduring pillars: science, ethics, and experience. These pillars support the three fundamental principles that shape radiological protection strategies: justification, optimisation, and application of dose limits.

Myocarditis is an inflammation of heart tissue. Cardiovascular magnetic resonance imaging (CMR) has emerged as an important non-invasive imaging tool for diagnosing myocarditis, however, interpretation remains a challenge for novice physicians. Advancements in machine learning (ML) models have further improved diagnostic accuracy, demonstrating good performance.

Background: Spleen-preserving distal pancreatectomy by robotic surgery is a safe and feasible surgical technique. Currently, spleen-preserving distal pancreatectomy represents an alternative to the classical distal pancreatectomy with splenectomy, in the case of benign and low-grade malignant diseases of the body or pancreas tail. The reasons for preserving the spleen are based on the reduction of postoperative complications, such as post-splenectomy infections, subphrenic abscess, portal thrombosis, pulmonary hypertension, thrombocytosis, and thromboembolism.

Copeptin in the diagnosis and management of renal tubular disorders.

Pediatr Nephrol

September 2025

Pediatric Nephrology Department, Biobizkaia Health Research Institute, Cruces University Hospital, Barakaldo, Spain.

Copeptin, a stable glycopeptide derived from the precursor of arginine vasopressin (AVP), has emerged as a valuable surrogate biomarker for AVP due to its stability and ease of measurement. This narrative review explores the physiological role of copeptin, its utility as a diagnostic and prognostic biomarker in different kidney diseases, and its clinical relevance in renal tubular disorders. The clinical application of copeptin as a diagnostic biomarker is best established in the differential diagnosis of polyuria-polydipsia syndrome (PPS), distinguishing nephrogenic diabetes insipidus (NDI) from central diabetes insipidus (CDI) and primary polydipsia (PP).

Somatic embryogenesis (SE) is an in vitro mass propagation system widely employed in plant breeding programs. However, its efficiency in many forest species remains limited due to their recalcitrance. SE relies on the induction of somatic cell reprogramming into embryogenic pathways, a process influenced by transcriptomic changes regulated, among other factors, by epigenetic modifications such as DNA methylation, histone methylation, and histone acetylation.

Background The prognostic value of baseline visual emphysema scoring at low-dose CT (LDCT) in lung cancer screening cohorts is unknown. Purpose To determine whether a single visual emphysema score at LDCT is predictive of 25-year mortality from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease (CVD). Materials and Methods In this prospective cohort study, asymptomatic adults aged 40-85 years with a history of smoking underwent baseline LDCT screening for lung cancer between June 2000 and December 2008.

Surface-Driven Electron Localization and Defect Heterogeneity in Ceria.

J Am Chem Soc

September 2025

Kathleen Lonsdale Materials Chemistry, Department of Chemistry, University College London, London WC1H 0AJ, U.K.

The exceptional performance of ceria (CeO) in catalysis and energy conversion is fundamentally governed by its defect chemistry, particularly oxygen vacancies. The formation of each oxygen vacancy (V) is assumed to be compensated by two localized electrons on cations (Ce). Here, we show by combining theory with experiment that while this 1 V: 2Ce ratio accounts for the global charge compensation, it does not apply at the local scale, particularly in nanoparticles.
