Development of Electrospun Biodegradable Reduced Graphene Oxide (rGO)/P3HB4HB Composite Nanofibrous Membranes for Enhanced Microbial Fuel Cell Performance

ABSTRACT Emerging bioelectrochemical platforms called microbial fuel cells (MFCs) allow for the simultaneous treatment of wastewater and the production of sustainable electricity. By enabling effective proton transport between the anode and cathode compartments, the proton exchan...

Leakage-conscious machine learning for supplied injury-risk label classification and longitudinal injury forecasting: a multi-dataset evaluation

Machine learning is increasingly used to model sports-related injury risk, but favorable performance may be misleading when outcome labels are externally assigned, proxy-driven, highly separable, or affected by outcome-proximal information. This study evaluated model credibility...

Rapid choroidal neovascularization after non-flap internal limiting membrane peeling for macular hole in a patient with AMD: a case report and literature review

Choroidal neovascularization (CNV) following macular hole (MH) surgery is a rare complication. While the exact pathogenesis remains unclear, previous reports in the literature suggest that it can occur in patients with pre-existing age-related macular degeneration (AMD) or macula...

Cardiorespiratory adaptations to high-intensity interval training in young boxers

Background: High-intensity interval training (HIIT) has been recognized for its effectiveness in enhancing cardiorespiratory fitness. However, the application of HIIT within boxing training remains underexplored. This study aimed to investigate the physiological adaptations induc...

Can preheated resin composite optimize bond strength and film thickness for indirect adhesive restorations?

Abstract Purpose Resin composite shows potential as a luting agent for indirect adhesive restorations, but its viability as an alternative to resin cement remains uncertain. This study aimed to evaluate the microtensile bond strength (µTBS) and film thickness of preheated resin c...

Adult Mixed Epithelial and Stromal Tumor of the Kidney Harbors Recurrent Whole Chromosome 12 Gain

Mixed epithelial and stromal tumor (MEST), including adult cystic nephroma (CN), is an uncommon benign renal neoplasm that mostly occurs in middle-aged women. To date, a comprehensive molecular genetic investigation of MEST and/or adult CN has not been performed. Fourteen archiva...

Inferior vena cava agenesis: Clinical presentation, imaging characteristics, and midterm outcomes with a proposed diagnostic algorithm

Objective Inferior vena cava agenesis (IVCA) is a rare developmental venous anomaly associated with proximal deep vein thrombosis (DVT) in young patients. Evidence guiding diagnostic and therapeutic strategies remains limited. We evaluated clinical presentation, imaging character...

Assessing Gamma Index Sensitivity to Selected Linear Accelerator Mechanical Errors Using Various Dosimetric Systems

Background: Volumetric modulated arc therapy (VMAT) for stereotactic body radiotherapy (SBRT) involves highly modulated dose distributions and steep dose gradients, increasing the importance of patient-specific quality assurance (QA). Gamma index analysis is widely used for compa...

Clinical and Therapeutic Effects of Adjacent Organ Invasion in Gastrointestinal Stromal Tumor (GIST) Cases

Background: This retrospective study aimed to investigate the clinical and therapeutic effects of adjacent organ invasion in gastrointestinal stromal tumor (GIST) cases. Methods: The files of 114 GIST patients from various centers who underwent surgery by the principal investigat...

Proteome Analysis of Different Tissues in Pregnant Women with Gestational Diabetes and Type 1 Diabetes Mellitus

BACKGROUND: Gestational diabetes mellitus (GDM) and type 1 diabetes mellitus (T1DM) represent distinct hyperglycemic states during pregnancy. Although proteomic alterations have been described in plasma and placental tissues in GDM, no study has comprehensively compared proteomic...

Radiographic Changes in Patellar Height Following Rapid Weight Loss After Sleeve Gastrectomy: A Retrospective Observational Study

Background/Objectives: Rapid weight loss following sleeve gastrectomy substantially reduces mechanical loading across the lower extremities, yet its effects on patellar height remain unknown. This study investigated early postoperative radiographic changes in patellar height foll...

Comparison and evaluation of the radiopacity of different posterior composites

The purpose of this research was to test the radiopacity of both bulk-fill and traditional composite resin materials via a digital radiography system. Additionally, it tested how the radiopacity of these restorative materials compared to the radiopacity of natural enamel and dent...

Real-world clinical use of large neutral amino acids in phenylketonuria: a nationwide survey from Turkey under reimbursement constraints

Abstract Background Phenylketonuria (PKU) requires lifelong dietary management, and large neutral amino acid (LNAA) supplementation has emerged as a potential adjunct therapy, particularly for individuals with poor dietary adherence. In Turkey, access to LNAA therapy is restricte...

Context-Aware Sequential Ranking for Dynamic Test Case Prioritization in Continuous Integration

Regression testing in continuous integration (CI) helps preserve delivered software value by exposing regressions early, but limited feedback windows make test order consequential. This study evaluates a leakage-safe dynamic test case prioritization framework that reconstructs jo...

Scleral buckling versus combined pars plana vitrectomy and scleral buckling in primary rhegmatogenous retinal detachment: a 20-year retrospective comparative study

Scleral buckling (SB) has been progressively displaced by pars plana vitrectomy (PPV) in the management of rhegmatogenous retinal detachment (RRD); however, this transition appears to be driven more by evolving surgical training patterns than by clear differences in outcome data....

Source-Study-Aware Validation and Explainable Machine Learning for Reliable Shear Capacity Assessment of Steel-Fiber-Reinforced Concrete Corbels

This study proposes a source-study-aware validation framework to estimate the shear capacity of stirrup-free steel-fiber-reinforced concrete corbels and assess the reliability and generalizability of machine-learning models in structural engineering. A database of 108 specimens,...

Microbial organization, biofilm architecture, and microbiota–host interactions in colorectal and gastric cancer

Emerging evidence suggests that the relationship between the microbiome and cancer is not determined solely by microbial presence, but is also influenced by the spatial organization and functional state of microbial communities, including their organization within biofilms. In co...

SETTLEMENT SYSTEMS AND SPATIAL ORGANIZATION IN THE PRE‐POTTERY NEOLITHIC UPPER TIGRIS REGION

Summary This article examines the settlement systems and spatial organization in the Upper Tigris region during the Pre‐pottery Neolithic (PPN), based on data from recent rescue excavations and ongoing systematic fieldwork. The approach focuses on location preferences, covering v...

Maternal bonding and psychological symptoms among women with and without COVID-19 infection: a comparative cross-sectional study

BACKGROUND: Childbirth during the COVID-19 pandemic involved infection-control measures and changes in maternity care that may have increased psychological stress and affected early mother-infant bonding, particularly among women infected at delivery. OBJECTIVE: This study aimed...

Domain specific associations of teacher self efficacy and perceived work related motivational conditions with multidimensional burnout

Teacher burnout is multidimensional, yet many studies rely on global scores that may obscure domain-specific links with personal beliefs and appraised work conditions. Using cross-sectional survey data from 751 teachers in Türkiye (SEM analytic N = 740 after multivariate outlier...
