TRPV1 Suppresses Microglial Inflammatory Activation to Ameliorate Schizophrenia-Associated Behaviors in Maternal Separation Rats.

Background And Hypothesis: Schizophrenia is linked to hippocampal dysfunction and microglial inflammatory activation. Our prior clinical findings revealed significantly reduced transient receptor potential vanilloid 1 (TRPV1) expression in both first-episode and recurrent schizophrenia patients, with levels inversely correlating with symptom severity, implicating TRPV1 dysfunction in disease progression. Preclinical maternal separation (MS) models recapitulate schizophrenia-like behavioral and synaptic deficits, paralleled by hippocampal microglial TRPV1 downregulation.

Particle stabilised high internal phase emulsion scaffolds with interconnected porosity facilitate cell migration.

A key challenge in bone tissue engineering (BTE) is designing structurally supportive scaffolds, mimicking the native bone matrix, yet also highly porous to allow nutrient diffusion, cell infiltration, and proliferation. This study investigated the effect of scaffold interconnectivity on human bone marrow stromal cell (BMSC) behaviour. Highly interconnected, porous scaffolds (polyHIPEs) were fabricated using the emulsion templating method from 2-ethylhexyl acrylate/isobornyl acrylate (IBOA) and stabilised with ~200 nm IBOA particles.

Comparison of Navier-Stokes and lattice Boltzmann solvers for subject-specific modelling of intracranial aneurysms.

Modelling cardiovascular disease is at the forefront of efforts to use computational tools to assist in the analysis and forecasting of an individual's state of health. To build trust in such tools, it is crucial to understand how different approaches perform when applied to a nominally identical scenario, both singularly and across a population. To examine such differences, we have studied the flow in aneurysms located on the internal carotid artery and middle cerebral artery using the commercial solver Ansys CFX and the open-source code HemeLB.

Model-Independent Test of Prerecombination New Physics: Measuring the Sound Horizon with Gravitational Wave Standard Sirens and the Baryon Acoustic Oscillation Angular Scale.

In a broad class of cosmological models where spacetime is described by a pseudo-Riemannian manifold, photons propagate along null geodesics, and their number is conserved, upcoming gravitational wave (GW) observations can be combined with measurements of the baryon acoustic oscillation (BAO) angular scale to provide model-independent estimates of the sound horizon at the baryon drag epoch. By focusing on the accuracy expected from forthcoming surveys such as the Laser Interferometer Space Antenna GW standard sirens and dark energy spectroscopic instrument (DESI) or Euclid angular BAO measurements, we forecast a relative precision of σ_{r_{d}}/r_{d}∼1.5% within the redshift range z≲1.

A protocol to develop a Quality Assessment Tool for Realist Synthesis (QUATRES).

A realist synthesis or review is a theory-driven, realist-informed interpretive approach to synthesizing secondary data, informing evidence-based practice, and explaining social phenomena. Realist syntheses use flexible and iterative methods to achieve this goal, including drawing on stakeholders' knowledge. Thus, realist syntheses require robust planning to be conducted and reported.

Advanced cancer patients' experience and perception of advance care planning at a university teaching hospital in Northern Tanzania.

Background: Advance care planning (ACP) is not formally implemented in Tanzanian healthcare. While the burden of non-communicable diseases continues to rise, most patients present at advanced stages of illness, highlighting the urgent need for ACP to support preference-based care.

Objectives: This study aimed to explore advanced cancer patients' experiences and perceptions of ACP at a university teaching hospital in Northern Tanzania.

UK recommendations for chimerism testing and monitoring following allogeneic haematopoietic stem cell transplantation (HSCT): Best practice consensus guidelines from the British Society for Blood and Marrow Transplant and Cellular Therapies (BSBMTCT), NHS England Genomic Laboratory Hub (GLH) Haematological Malignancies Working Group, UK Cancer Genetics Group (UKCGG) and the UK National External Quality Assessment Service for Leucocyte Immunophenotyping (UK NEQAS LI).

In allogeneic haematopoietic stem cell transplantation (HSCT), important clinical decisions depend upon assessment of chimerism, including immunosuppressant dosing and donor lymphocyte infusions (DLI), which in turn can have major impacts on disease control, graft-versus-host disease (GVHD), immunity and ultimately patient survival. There is a complex range of clinical and laboratory procedural considerations including methodology of testing, types of cell subset selection, frequency of testing, urgency of turnaround times (TATs), interplay with measurable residual disease (MRD) monitoring and duration of testing post-transplant. These aspects are routinely adapted according to disease indication, patient characteristics, donor source and intensity of transplant technique.

Indications for haematopoietic cell transplantation and CAR-T for haematological diseases, solid tumours and immune disorders: 2025 EBMT practice recommendations.

For over two decades, the EBMT has updated recommendations on indications for haematopoietic cell transplantation (HCT) practice based on clinical and scientific developments in the field. This is the ninth special EBMT report on indications for HCT for haematological diseases, solid tumours and immune disorders. Our aim is to provide guidance on HCT indications according to prevailing clinical practice in EBMT countries and centres.

Exploring experiences of the regulatory toxicology system: system-level promoters and inhibitors of new approach methodologies.

The transition from traditional animal-based approaches and assessments to New Approach Methodologies (NAMs) marks a scientific revolution in regulatory toxicology, with the potential of enhancing human and environmental protection. However, implementing the effective use of NAMs in regulatory toxicology has proven to be challenging, and so far, efforts to facilitate this change frequently focus on singular technical, psychological or economic inhibitors. This article takes a system-thinking approach to these challenges, a holistic framework for describing interactive relationships between the components of a system of interest.

Availability of benign missense variant "truthsets" for validation of functional assays: Current status and a systematic approach.

Multiplex assays of variant effect (MAVEs) provide promising new sources of functional evidence, potentially empowering improved classification of germline genomic variants, particularly rare missense variants, which are commonly assigned as variants of uncertain significance (VUSs). However, paradoxically, quantification of clinically applicable evidence strengths for MAVEs requires construction of "truthsets" comprising missense variants already robustly classified as pathogenic and benign. In this study, we demonstrate how benign truthset size is the primary driver of applicable functional evidence toward pathogenicity (PS3).

Evaluating the Implementation of Online Postal Self-Sampling for Sexually Transmitted Infections in England: Multisite Qualitative Study.

Background: Online postal self-sampling (OPSS) allows service users to screen for sexually transmitted infections (STIs) by ordering a self-sampling kit online, taking their own samples, returning them to a laboratory for testing, and receiving their results remotely. OPSS availability and use has increased in both the United Kingdom and globally the past decade but has been adopted in different regions of England at different times, with different models of delivery. It is not known why certain models were decided on or how implementation strategies have influenced outcomes, including the sustainability of OPSS in sexual health service delivery.

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.

Genome-Wide Insights Into the Genes and Pathways Shaping Human Foveal Development: Redefining the Genetic Landscape of Foveal Hypoplasia.

Purpose: To define the genetic architecture of foveal morphology and explore its relevance to foveal hypoplasia (FH), a hallmark of developmental macular disorders.

Methods: We applied deep-learning algorithms to quantify foveal pit depth from central optical coherence tomography (OCT) B-scans in 61,269 UK Biobank participants. A genome-wide association study (GWAS) was conducted using REGENIE, adjusting for age, sex, height, and ancestry.

Modeling the time evolution of the structure factor during polymeric spinodal decomposition using dynamic mode decomposition.

The development of the microstructure during polymeric spinodal decomposition can be monitored in real time using small-angle scattering. Information about the microstructure can be deduced from measurements of the structure factor-a quantity directly proportional to the scattered intensity. While the time evolution of the structure factor can be measured relatively easily, modeling it has proved to be much more difficult.

Background: Personalized Interactive Music Systems (PIMSs) are emerging as promising devices for enhancing physical activity and exercise outcomes. By leveraging real-time data and adaptive technologies, PIMSs align musical features, such as tempo and genre, with users' physical activity patterns, including frequency and intensity, enhancing their overall experience.

Objective: This exploratory systematic review and meta-analysis evaluates the effectiveness of PIMSs across physical, psychophysical, and affective domains.

serojump: A Bayesian tool for inferring infection timing and antibody kinetics from longitudinal serological data.

Understanding acute infectious disease dynamics at individual and population levels is critical for informing public health preparedness and response. Serological assays, which measure a range of biomarkers relating to humoral immunity, can provide a valuable window into immune responses generated by past infections and vaccinations. However, traditional methods for interpreting serological data, such as binary seropositivity and seroconversion thresholds, often rely on heuristics that fail to account for individual variability in antibody kinetics and timing of infection, potentially leading to biased estimates of infection rates and post-exposure immune responses.
