This study reports novel bilayer active packaging films based on corona-treated low-density polyethylene (LDPE) coated with gelatin/glycerol (Gel/Gl) incorporating eugenol@natural zeolite (EG@NZ) or carvacrol@natural zeolite (CV@NZ) nanohybrids. All Gel-based films demonstrated o...

Exergy‐Based Performance Analysis and Optimization of Autonomous Fuel Cell‐Based Energy Systems With Solid Oxide and Proton Exchange Membrane Fuel Cells Fed by Biogas of Variable Composition

ABSTRACT This study presents a unified thermodynamic and exergy‐based assessment of autonomous fuel cell energy systems operating on biogas with varying compositions. Two alternative configurations—a solid oxide fuel cell (SOFC)‐based system and a proton exchange membrane fuel ce...

Unilateral Versus Bilateral Percutaneous Kyphoplasty for Single-Level Thoracolumbar Osteoporotic Vertebral Compression Fractures: A Systematic Review and Meta-Analysis

Background/Objectives: The optimal surgical approach for Percutaneous KyphoPlasty (PKP) in patients with recent single-level Osteoporotic Vertebral Compression Fractures (OVCFs) remains controversial. Most available previous meta-analyses included studies with variable heterogene...

Quality of Life and Job Satisfaction Among Nurses and Physicians in Greek Public Hospitals: Associations with Protocol-Based Work and Workplace Characteristics

Background: Health-related quality of life (HRQoL) and job satisfaction are important indicators of nurses and physicians’ wellbeing and system sustainability, particularly under conditions of high clinical demand. Although organizational determinants of nurses and physicians’ we...

Arbovirus co-circulation and epidemiological convergence in a changing climate: challenges for surveillance, diagnosis and public health preparedness

Abstract Arboviral diseases are undergoing substantial epidemiological changes driven by climate change, urbanization, global mobility, vector expansion, and evolving ecological conditions. These processes increasingly favor the geographic overlap and co-circulation of multiple a...

Childhood emotional abuse and anger expression in Greek adolescents: a pilot school-based study

= .45). These preliminary findings suggest that higher levels of self-reported childhood emotional abuse are associated with greater anger expression among adolescents, whereas anger control does not appear to be related. Given the pilot nature of the study and its modest conveni...

SHAPRP: A SHAP-Guided Framework for Efficient RSS Estimation in 5G/B5G Networks

As bandwidth-intensive applications proliferate and the usage of wireless devices surges, fifth-generation (5G) and beyond (B5G) networks are challenged to enhance coverage, reduce latency, and improve efficiency. The application of machine learning (ML) models for received signa...

Applying Ten Governance and Accounting Principles to Fraud Risk in Tourism: Selected International Evidence and the Greek Case

Tourism ranks among the world’s most economically significant sectors, yet fraud, tax evasion and undeclared work are, in many service-dominated and SME-heavy tourism economies, recurring structural features rather than isolated anomalies. Governance and fraud research, however,...

Anatomical variants of circumaortic left renal vein

The circumaortic left renal vein (CLRV) is a critical retroperitoneal vascular variant.Current classification systems frequently omit possible morphologies.This study aims to delineate intricate CLRV patterns and propose a preliminary classification framework.Contrast-enhanced ab...

IGF-1Eb Isoform Immunoreactivity May Be Associated with Placental Dysfunction and Vascular Pathology in Fetal Growth Restriction (FGR)

Background: Fetal growth restriction (FGR) is associated with placental dysfunction and adverse perinatal outcomes. Although insulin-like growth factor-1 (IGF-1) signaling is important for placental and fetal development, the mRNA expression, immunopositivity and potential biolog...

The Role of Clomiphene Citrate in Gonadotropin Stimulation Protocols in Poor Responders: A Mini-Review of Recent Clinical Evidence

Diminished ovarian reserve (DOR) and poor ovarian response (POR) remain among the most challenging conditions in assisted reproductive technology, and no optimal stimulation strategy has been established. Clomiphene citrate (CC), a selective estrogen receptor modulator that augme...

An Ecotoxicological Perspective on Bivalve Safety Frameworks: Linking HAB Management and Microbiological Limits to Physiological Responses in Shellfish

Harmful algal blooms (HABs) pose a growing ecotoxicological threat to bivalve molluscs and their consumers. Current regulatory frameworks governing shellfish safety, however, rely on acute human toxicity limits that poorly capture the biological complexity of bivalve–HAB interact...

Paging Dr. Patient: a diagnosis of Greek public hospitals through sentiment analysis

PURPOSE: We examine the topics and the dimensions of patient satisfaction and their implications for Greek public hospitals. DESIGN/METHODOLOGY/APPROACH: We measure patient satisfaction through the sentiment analysis of the relative ratings and commendation submitted to Google re...

Musical Feature Processing and Learning Difficulties in Greek School-Aged Children: Piloting of a Screening Tool for Amusia
