Composite Uric Acid Index for Prediction of Significant Coronary Stenosis on Computed Tomography Angiography

OBJECTIVE: A recently proposed uric acid index combining fasting glucose, triglycerides, and uric acid has shown promise in cardiovascular risk stratification. It was assessed whether the index could predict significant coronary artery stenosis (≥50%) on coronary computed tomogra...

Investigating the effect of VR-mediated pragmatics instruction on L2 refusal strategies

Pragmatic competence remains a vital yet often overlooked area in instructed second language learning, particularly in the domain of refusal speech acts. This quasi-experimental study investigated the effect of VR-mediated explicit pragmatics instruction on L2 learners’ refusal s...

Influence of spice enrichment on consumer acceptance of plant-based meat alternatives

The growing interest in plant-based meat alternatives has intensified the need to optimize their sensory properties to improve consumer acceptance. This study investigated the effect of spice enrichment on the sensory evaluation of plant-based meatball formulations during consume...

Buckling of carbon nanotubes using molecular dynamics simulation: Investigating the effect of boron doping by considering the interaction energy

This study investigates the atomic-scale stability and buckling behavior of boron-doped carbon nanotubes (CNTs) using molecular dynamics simulations. After equilibration in the NVT ensemble, we applied compressive deformation to evaluate the mechanical response and structural evo...

Cognitive Performance Under AI Advice: Development and Initial Validation of a CHC-Informed Assessment for Organizational Decision-Making

Artificial intelligence (AI) is increasingly embedded in organizational decision-making, requiring employees not only to use AI-generated recommendations but also to evaluate their quality and determine when reliance is appropriate. Although established research examines behavior...

PURPOSE: This study sought to evaluate the effectiveness of Shock Wave Enhanced Emission Photoacoustic Streaming (SWEEPS), XP-endo Finisher (XPF), Passive Ultrasonic Irrigation (PUI), and Conventional Syringe Irrigation (CSI) in the removal of calcium hydroxide (CH) from the mesi...

Biliary complications in pediatric living donor liver transplantation: An international multicenter analysis of risk and prognostic factors

Biliary reconstruction is often considered the Achilles’ heel of liver transplantation, yet risk factors and outcomes remain poorly defined, particularly in pediatric living donor liver transplantation (LDLT). This international multicenter study aims to identify predictors of bi...

Assessing Readiness for AI-Human Integration Using a Hesitant Fuzzy Analytic Hierarchy Process: An Application in the Banking Sector

With AI being incorporated into the core functions of organizations, understanding whether or not an organization is ready to work in conjunction with humans using AI will continue to grow in importance. Therefore, this study proposes a multi criteria decision making (MCDM) based...

Optimizing In Vitro Organogenesis in Sunflower (Helianthus annuus L.) Using Cotyledon and Root Node Explants

Sunflower (Helianthus annuus L.) is widely recognized as a recalcitrant species in tissue culture, which severely restricts its micropropagation and genetic transformation efficiency. To address this limitation, this study establishes a novel, highly efficient, and reproducible i...

Clinical Impact of Fingolimod-Associated Lymphopenia in Multiple Sclerosis: A Real-World Cohort Study

Background and Objectives: Fingolimod, a sphingosine-1-phosphate receptor modulator, is an effective disease-modifying therapy for relapsing forms of multiple sclerosis (MS). Although lymphopenia is a well-recognized pharmacological effect, its clinical significance remains uncer...

Association of pre-transplant cardiac risk phenotype and coronary revascularization strategy with one-year mortality after living-donor kidney transplantation: a single-center cohort
