Weight Loss or Muscle Loss? Cellular Mechanisms and Clinical Strategies for Preserving Lean Mass During GLP ‐1‐Based Therapy

ABSTRACT Glucagon‐like peptide‐1 receptor agonists and newer dual‐ and triple‐incretin receptor agonists have transformed obesity treatment by producing substantial and sustained weight loss. However, reported reductions in lean body mass have raised concerns about potential skel...

Valuation of life-insurance contracts with multiple benefits under stochastic mortality: A QP-Rule framework in light of COVID-19

This paper examines the valuation of a life insurance contract combining a Guaranteed Minimum Income Benefit (GMIB), a surrender benefit, and a death benefit under stochastic mortality and financial risks. Building on the established QP-rule valuation approach and a hybrid financ...

Differentiation of cervical caries and cervical burnout on orthopantomographic images: a radiomics-based machine learning approach

To evaluate the diagnostic performance of machine learning (ML) algorithms based on radiomic features extracted from orthopantomographic (OPG) images in differentiating cervical caries from cervical burnout. A total of 170 OPG images were retrospectively analyzed, including 85 ce...

Are arterial and venous procedure-related thromboses the same disease? a clinical and hematological comparative study

Arterial and venous thrombosis are traditionally regarded as pathophysiologically distinct processes, yet procedure-related thrombosis following vascular access offers a controlled setting in which an identical iatrogenic trigger (endothelial injury) precipitates thrombosis in di...

The Political Consequences of Anti-Populism: Revisiting the Populism Debates in Türkiye (1980s–1990s)

This article revisits debates on populism among Turkish leftist and Marxist intellectuals during the 1980s and 1990s. While contemporary scholarship largely treats populism as a political style, discursive strategy, or new regime type, these earlier debates analysed it through th...

Computed tomography-derived projected morphometry of four zygomatic sutures: distinct geometric profiles and bilateral agreement

Zygomatic sutures are key landmarks in midfacial trauma, yet comparative data on their projected geometry and individual-level bilateral correspondence within a common computed tomography (CT) protocol remain limited. We compared the zygomaticomaxillary, sphenozygomatic, temporoz...

Development and Patient-Level Internal Validation of an MRI-Based Radiomics Machine Learning Model for Preoperative Prediction of Cervical Lymph Node Metastasis in Oral Squamous Cell Carcinoma: A Pilot Study

Background/Objectives: Cervical lymph node metastasis (LNM) is the main prognostic factor in oral squamous cell carcinoma (OSCC) and guides the extent of neck treatment. This retrospective pilot study aimed to develop MRI-based radiomics machine learning models for the preoperati...

Contributions to the Mitochondrial Genetic Variation and Phylogeny of the Eurasian Otter (Lutra lutra)

Abstract The mitochondrial CYTB and COI markers of a road-killed Eurasian otter (Lutra lutra) specimen from western Türkiye were analyzed within a phylogenetic context. Given the high haplotype similarity to European and Russian lineages, the Turkish sample was evaluated alongsid...

Extreme low and high temperature treatments as a non-chemical control strategy for the almond moth, Ephestia cautella in dried figs

Mortality responses of different developmental stages of the almond moth, Ephestia cautella (Walker) (Lepidoptera: Pyralidae), to extreme low and high temperatures were evaluated under laboratory and field-scale conditions to assess the feasibility of temperature-based control st...

Neonatal Niemann–Pick type C: a case series integrating clinical findings, structural modeling and ACMG-based variant interpretation

Abstract Background Niemann–Pick disease type C (NPC) is a rare autosomal recessive lysosomal storage disorder that can present in the neonatal period with cholestasis and hepatosplenomegaly, making early diagnosis challenging. We report a case series of three neonates evaluated...

Sidewall-Based Three-Dimensional DC Resistivity Imaging for Identifying Potentially Water-Bearing Zones Around an Operational Railway Tunnel

Groundwater ingress and moisture-related deterioration threaten railway tunnels in fractured and hydrogeologically active terrains. This study evaluates sidewall-based three-dimensional (3D) direct current resistivity (DCR) imaging for investigating potentially water-bearing cond...

Effects of naringenin on superovulation in mice: evaluation of zygote and blastocyst development, histopathology, and molecular docking insights

CONTEXT: Naringenin is a citrus-derived flavanone with documented antioxidant, anti-inflammatory, and steroidogenic modulatory properties; yet, its effects under gonadotropin-stimulated superovulation have not been investigated. AIMS: This study evaluated the impact of naringenin...

Forecasting Türkiye’s salmon exports: A multi-method assessment of market dynamics and country-specific prospects

Türkiye has rapidly emerged as an important producer and exporter of Turkish salmon, yet the future trajectory of its exports may differ substantially across destination markets. This study examines the short-term country-specific prospects of Türkiye’s salmon exports and identif...

The effect of Lexical-oriented vocabulary instruction on seventh-grade students' use of vocabulary in writing

Background Effective vocabulary use lies at the heart of successful writing, yet many students struggle to use words accurately and appropriately in context. Purpose This study examined the effect of Lexical-oriented vocabulary instruction on the lexical quality of seventh-grade...

Statistical Inference for Multi-sample of Geometric Processes with Lognormal Distribution

The geometric process is an important counting process model that serves as an alternative to non-homogeneous Poisson process models. It is widely used in reliability analysis, particularly in the modeling of repairable systems, due to its monotonic behaviour. Accurate statistica...

Standards for practical management of drug hypersensitivity reactions to intravenous drugs and proactive early allergy involvement before referral: A WAO Statement

Hypersensitivity reactions to intravenous therapies—including antibiotics, chemotherapeutics, biologics, anesthesia agents, and contrast media—pose significant challenges in acute care settings. These reactions often occur outside the purview of allergy specialists, leading to de...

Acute exercise-related changes in hematological parameters and lymphocyte subsets before and after short‑term rapid weight loss in national‑level wrestlers: a pilot study

Abstract Background Rapid weight loss (RWL) is commonly used by wrestlers to qualify for lower weight categories, but the combined effects of RWL and intense exercise on circulating immune cell profiles, particularly lymphocyte subsets, remain incompletely characterized. This stu...

Clinical management, antifungal susceptibility, and predictors of 28-day mortality in Candidozyma auris candidemia: a single-center cohort study

Candidozyma auris (Candida auris) candidemia is a serious healthcare-associated infection with substantial mortality and limited treatment options. We retrospectively evaluated adult patients with C. auris candidemia at a tertiary care center between June 2022 and December 2025 t...

Effects of Different Activation and Obturation Techniques on the Depth of Sealer Penetration into Lateral Canals

Aim:A successful outcome of root canal treatment is contingent upon establishing a three-dimensional seal that encompasses the obturation of lateral and accessory canals. This study investigated the impact of different activation strategies and obturation techniques on the depth...

The bactericidal potential of liquid extracts against Yersinia ruckeri: a comparative in vitro assessment

Enteric redmouth disease, caused by Yersinia ruckeri, is a major bacterial disease of farmed rainbow trout (Oncorhynchus mykiss), and rising antibiotic resistance has increased the need for alternative control agents. This study compared the in vitro activity of eight commercial...
