The continuous quest for materials capable of providing sustained release of antimicrobial drugs is particularly important for indwelling medical applications. In this study, we utilized amoxicillin as a model active pharmaceutical ingredient (API) to investigate the feasibility of using porous media – specifically, functionalized calcium carbonate (FCC) microparticles – as a primary drug carrier

The article presents Fady Joudah’s Textu as an innovative combination of poetry (haiku) and communication technology (text messaging). The paper questions the traditional distinction between literature and other media, exploring how digital formats affect the understanding of “text” and the experience of reading. The authors of the article invoke intermedial theory (Lars Elleström, Beate Schirrmac

Background: First-line managers in healthcare operate in increasingly complex environments marked by high demands, rapid change, and limited resources. These conditions impact their health, leadership capacity, and the sustainability of their roles. While previous research has addressed various aspects of leadership in healthcare, there is a lack of studies focusing specifically on how first-line

Advances in biomarker technology, digital cognitive assessments, and amyloid-targeting therapies have redefined the opportunities for accurate and early diagnosis and care of Alzheimer's disease (AD). These advances also create new possibilities for intervention before the onset of cognitive impairment. This paradigm shift has increased the focus on Stages 1 and 2 of AD, in which individuals are c

The global elimination of viral hepatitis by 2030 remains an ambitious goal that hinges not only on diagnostics and therapeutics but fundamentally on the strategic use and continued innovation of vaccines. The ESCMID Study Group for Viral Hepatitis (ESGVH) convened to examine the role of vaccination as the cornerstone of hepatitis prevention, from long-established immunisation programs to emerging

Background: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) enables sensitive detection and staging of prostate cancer, yet its relationship with long-term survival remains unclear. This study aimed to assess whether total lesion volume (TLV) measured on [18F]PSMA-1007 PET/CT predicts overall survival (OS) in prostate cancer patients. Methods: A co

Air pollution is the world’s deadliest environmental risk factor. Yetthere is little effort to educate the public about personal exposureto pollutants such as particulate matter (PM). This paper presentsthe design and implementation of a portable sensor box (PSB) tocollect local, spatially highly resolved particulate matter data. Tocounteract common inaccuracies in mobile particulate matter mea-su

The European Commission defines the Green Transition as the transformation set out in the European Green Deal. Ensuring that this transition is just is both an ethical requirement and a practical condition for maintaining public support and policy effectiveness. This Perspective proposes a multidimensional framework for assessing justice in Green Transition policies, encompassing distributional, p

Background: Increasing healthcare demands and a growing nursing shortage contribute to high workloads, psychosocial strain, and risks to care quality. Organisational conditions, job demands, and resources strongly influence nurses’ well-being, retention, and performance. Aim: To examine how nurses balance organisational demands and opportunities, and how these factors relate to work environment, w

The mountain front recharge (MFR) process significantly influences the movement of water and dissolved organic carbon (DOC) in alpine catchments. However, no existing watershed models can adequately simulate this process, hindering accurate quantification of streamflow and DOC dynamics. To address this gap, this study explicitly incorporated the MFR process into a watershed-scale integrated water–

Ni1+δSn (δ = 0.2, 0.4) and Ni1+δ(In/Sb) (δ = 0.1–0.5) (NiAs/Ni2In type) were synthesized, and their crystal structures were studied in this report. In Ni1+δ(In/Sb), the excess nickel atoms (δ = 0.1–0.5) occupy the vacant trigonal bipyramidal interstitial sites in the NiAs-type structural arrangement, leading to the evolution of a fully disordered to ordered superstructure through a series of incom

Aims Social anxiety disorder (SAD) is one of the most common anxiety disorders and is associated with significant impairment and societal costs. The association between SAD and mortality remains poorly understood, partly because in epidemiological research it is rarely studied independently from other anxiety disorders. In this population-based matched cohort and sibling control study, we estimate

Purpose: The purpose of this in-depth interview study was to explore how parents of children with sensorineural hearing loss (SNHL) experienced genetic testing and whether they experienced risks and benefits. Background: Most children with SNHL have a genetic etiology, which can be identified through genetic sequencing. A genetic test does not influence treatment, and whether patients and parents

This paper investigates a behavioral-feedback SIR model in which the infection rate adapts dynamically based on the fractions of susceptible and infected individuals. We introduce an invariant of motion and we characterize the peak of infection. We further examine the system under a threshold constraint on the infection level. Based on this analysis, we formulate an optimal control problem to keep

Abstract – Background: Cytologic examination of lymph nodes and serous effusions is of value in the diagnosis of small cell lymphomas. The World Health Organisation (WHO) has recently published a reporting system relating to the cytologic examination of lymph nodes, spleen, and thymus to standardise the approach to reporting such specimens. Summary: An overview of the WHO reporting system is given

Enhancing the transformation-induced plasticity effect in steel-based binders through deformation-induced martensitic transformation requires careful control of the austenite stability. This study investigated the effect of binder fraction on the thermal stability of austenite in the WC-(Fe,Ni) system with different binder contents within the WC + binder + graphite equilibrium region. Binder marte

Conventional or ‘true’ memory CD8+ T cells (TTM) arise from immunologically naive T cells that circulate in the periphery after selection in the thymus. During infection or immunization by a foreign antigen, naive T cells can receive antigen-specific activation signals after recognition of MHC-antigenic peptide complexes. But the CD8+ T-cell population in immunologically naive hosts is not restric

The number of people seeking help for mental illness is increasing across all ages, creating a major burden for individuals, families, and the society. While personalized medicine is advancing in other fields, diagnosis and treatment of mental disorders remain largely symptom-based and fail to capture individual, sex, and gender differences in risk, manifestation, and treatment response. Early sig

Effective control over the alignment of 2D nanomaterials in solution is critical for optimizing their macroscopic properties. However, the fundamental factors governing this alignment remain poorly understood. This study addresses this gap by investigating the disorder-to-order transition states of Ti3C2Tx MXene sheets. We specifically examine the interplay among sheet sizes, concentrations, and s
