Pulmonary surfactant protein SP-C regulates lipid vesicle uptake by alveolar type II cells and macrophages: Role of lipids, palmitoylation, and environment.

Pulmonary surfactant protein C (SP-C) may play a key role in alveolar homeostasis by modulating vesicle uptake in alveolar cells. This study explores how SP-C regulates internalization of model unilamellar lipid vesicles by type II alveolar epithelial cells (AECII) and alveolar macrophages (AMϕ), focusing on the effect of lipid composition, palmitoylation state, and interactions with external stimuli like lipopolysaccharides (LPS) or the other hydrophobic surfactant protein SP-B. Using fluorescence-based techniques, we demonstrated that SP-C enhances vesicle uptake in a lipid-dependent manner.

3D bioprinted cell-laden GrooveNeuroTube: a multifunctional platform forneural cell migration and growth studies.

Extensive peripheral nerve injuries often lead to the loss of neurological function due to slow regeneration and limited recovery over large gaps. Current clinical interventions, such as nerve guidance conduits (NGCs), face challenges in creating biomimetic microenvironments that effectively support nerve repair. The developed GrooveNeuroTube is composed of hyaluronic acid methacrylate and gelatin methacrylate hydrogel, incorporating active agents (growth factors and antibacterial agents) encapsulated within an NGC conduit made of 3D-printed PCL grid fibers.

This study examines the long-term effects of OA on Arbacia lixula using a natural volcanic CO vent at Fuencaliente, La Palma (Canary Islands) as an analogue of future conditions. We analyzed the external morphology, skeletal strength, mineralogy, and growth of A.

Uncovering a novel role of nAChRs in oxidative stress-mediated vascular dysfunction in COPD.

Tobacco smoke is the main risk factor for the development of chronic obstructive pulmonary disease (COPD). Despite current therapies alleviate symptoms there are limitations in the efficacy of treatments to curb its cardiovascular morbidities, particularly vascular dysfunction and the development of pulmonary hypertension. Our previous studies demonstrate that cigarette smoke directly contributes to pulmonary arterial dysfunction.

Graphite furnace atomic absorption spectrometry as a tool to track the progress of photochemical synthesis of gold nanoparticles.

Gold nanoparticles (Au NPs) are widely used in diverse technological and scientific applications due to their unique optical and catalytic properties. These properties are strongly influenced by the size, shape, composition, and/or concentration of the NPs, which in turn depend on the synthesis conditions. Therefore, the development of simple, cost-effective, and reliable analytical methods for their characterization is essential.

Selected comparative aspects and unexpected findings in acute phase proteins and other biomarkers of animal health and welfare.

Recent years have seen advances in clinical biochemistry of domestic animals which have highlighted comparative differences between species and have also identified fundamental aspects of the biochemical mechanisms in physiological conditions and disease, that have implications across species, including human, health and welfare. From investigations in diverse species using biochemical, immunological, proteomic and metabolomic approaches a series of species particularities and unexpected results for some biomarkers have been made. These observations cover (1) the differences between species in the acute phase protein (APP) response to infection and inflammation; (2) the non-hepatic synthesis and release in the mammary gland, adipose tissue and intestine of APP (3) the response of haptoglobin (HP) as a biomarker for stress; (4) observations in non-mammalian species related to hemopexin and HP; (5) the response of bile acids in milk to mastitis; (6) barley serine protease inhibitors being identified in bovine faeces; (7) alkaline phosphatase being present in bovine nasal secretion; (8) saliva findings with analytes such as adenine deaminase showing different activity between saliva and serum and a detergent-like surfactant protein, latherin being found in equine saliva and sweat and (9) serum enzymes and selective muscle protein reaction of Atlantic salmon as an example of the differences in biochemistry between terrestrial and aquatic species.

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

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.

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.

Controlling collagen I orientation on polyetheretherketone implants to improve epithelial sealing.

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)).

Outcomes following transition from ibrutinib to zanubrutinib in patients with Waldenström macroglobulinemia from ASPEN.

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.

A phylogenetic approach to prioritising crop wild relatives in Brassiceae (Brassicaceae) for breeding applications.

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.

Natural history and development of a novel composite endpoint in patients with alcohol-associated Hepatitis: Data from a prospective multicenter study.

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.

ICTUSCOG: Poststroke cognitive impairment following nondisabling stroke: Study protocol of a spanish multicentre prospective cohort study.

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.

AHL-based QS signalling promotes uropathogenic Escherichia coli settlement through the de-repression of biofilm formation by SdiA.

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.

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.

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.

Optimizing Robotic Spleen-Preserving Distal Pancreatectomy: Strategies and Innovations to Enhance Safety and Efficacy.

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.

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).
