Prophylactic Home‐Based Exercises During Radiotherapy in Head and Neck Cancer: A Randomized Controlled Trial

OBJECTIVE: This study investigated the efficacy of a prophylactic, home-based exercise program administered concomitantly with radiotherapy in patients with head and neck cancer to preserve swallowing function, postural alignment, and cervical range of motion, while assessing lym...

The effect of systemic inflammation on locoregional colon cancer recurrence

Curative-intent treatment fails to prevent recurrence in a significant proportion of patients with locoregional colon cancer. Systemic inflammation plays a critical role in colorectal cancer progression. We evaluated the association between preoperative systemic inflammatory mark...

Cross-cultural adaptation and psychometric properties of the Turkish version of the Dresden Fall Questionnaire (DREFAQ-Tr) in Parkinson’s disease

Abstract Background Falls are a major complication of Parkinson’s disease and require reliable patient-reported assessment. The Dresden Fall Questionnaire (DREFAQ) is a brief tool assessing falls and related fear. This study aimed to translate and cross-culturally adapt the DREFA...

Investigation of Crashworthiness Characteristics of Sandwich Panels Inspired by the Mantis Shrimp Dactyl Club

The growing demand for lightweight, crashworthy structures in aerospace, automotive, and protective engineering has motivated the development of sandwich panels with high stiffness-to-weight ratios and strong energy absorption. This study investigates the crashworthiness of addit...

Militarization, Hindu Nationalist Legitimacy, and Majoritarian Politics in Modi’s India

The relationship between religion, nationalism, and political violence is shaped through direct acts of conflict as well as through the security discourses, institutions, and symbolic practices that define who belongs to the nation and who is represented as a threat. Militarizati...

Microbial diversity in the Pale tussock moth, Calliteara pudibunda L., 1758 (Lepidoptera: Erebidae) larvae in the Eastern beech forest in Türkiye

The Pale tussock moth, Calliteara pudibunda L., 1758 (Lepidoptera: Erebidae) is an important defoliator of deciduous forests, particularly Fagus orientalis Lipsky (Fagales: Fagaceae), with recurrent outbreaks in Türkiye. Despite its ecological and economic importance, its microbi...

Performance of Asphalt Mixtures Hybrid-Modified with Industrial Diatomite By-Products and Different Microfibres

This study evaluated asphalt mixtures incorporating two diatomite types (D1 and D2) at contents of 10% and 15% by binder weight and three fibre treatments added by aggregate weight: polyacrylonitrile (PAN) (0.065%), polyethylene terephthalate (PET) (0.10%), and basalt fibre (0.30...

Toll-like Receptor Signaling Beyond Infection in Urinary Bladder Dysfunction: Molecular Insights and Therapeutic Implications

Lower urinary tract dysfunction is highly prevalent and imposes a substantial individual and societal burden. Yet, current pharmacotherapies offer only limited symptomatic relief and are constrained by adverse effects and poor adherence. Toll-like receptors (TLRs), and Toll-like...

A spray‐dried dual microbial Wettable powder formulation: optimization and greenhouse efficacy against Western flower Thrips

Abstract BACKGROUND This study aimed to develop and evaluate a spray‐dried wettable powder (WP) formulation containing the entomopathogenic bacterium Serratia marcescens and the fungus Metarhizium flavoviride for the control of Frankliniella occidentalis . RESULTS The formulation...

The effect of a new subtype classification system on prognosis and outcome analysis in pediatric extension-type Gartland type III distal humerus supracondylar fractures

Abstract Objective The aim of this study was to investigate the association of a new, isthmus-referenced subtype classification system with prognosis and clinical-radiological outcomes in pediatric extension-type Gartland type III distal humerus supracondylar fractures. Materials...

Diagnosis, management, and prevention of Crimean-Congo haemorrhagic fever: a Delphi-based consensus study in Türkiye

Background Crimean-Congo haemorrhagic fever (CCHF) is a widely distributed viral haemorrhagic fever with expanding geographic range. As new regions encounter the disease, clinicians must make high-stakes decisions despite limited standardised management frameworks. Methods In thi...

Modeling the combined effects of the 2023 Türkiye–Syria earthquake and an Atmospheric River event on landslide hazard

Abstract. The 6 February 2023 Türkiye–Syria earthquake doublet triggered thousands of coseismic landslides. On 14–15 March, an Atmospheric River (AR) delivered up to 183 mm of rainfall across the seismically weakened region, triggering hundreds of additional landslides and debris...

A refined adaptive logistic-trigonometric shear deformation theory for the precise bending analysis of functionally graded plates

This study presents a refined Logistic-Trigonometric Shear Deformation Theory (LTHT) for the bending and interlaminar stress analysis of functionally graded (FG) plates. The proposed theory utilizes a hybrid shape function that incorporates a logistic (sigmoid) component and a tr...

Trauma burden, coping patterns, and psychological symptoms in Ahiska Turkish children and adolescents displaced following the Ukraine war: a cross-sectional study

War-related displacement may affect youth mental health through direct trauma exposure, family-level trauma burden, and coping processes. Ahiska Turkish families displaced after the Ukraine war are a historically important group because recent displacement may occur against a bac...
