Physics-Guided Bioinspired Multi-Objective Optimization for Explainable Drying-Stage Identification in an R290/R600a Waste-Heat Drying System

Integrating low-global-warming-potential refrigerants, waste-heat recovery, and intelligent process monitoring offers a promising route to energy-efficient drying systems. This study experimentally compares the natural refrigerants R290 and R600a in a vapor-compression refrigerat...

Beyond Seizure Suppression: Caffeic Acid Phenethyl Ester and 10-Hydroxy-2-Decenoic Acid Improve Anxiety-like and Cognitive Behaviors in PTZ-Challenged Zebrafish

Epilepsy is associated with recurrent seizures and behavioral and cognitive disturbances, highlighting the importance of assessing behavioral outcomes alongside seizure severity. Caffeic acid phenethyl ester (CAPE) has shown neuroprotective activity, whereas evidence for the neur...

A two-layer degradation-aware energy management framework for renewable power grids with battery and hydrogen storage

High renewable energy penetration supports sustainable power generation; however, intermittency, component aging, and long-term performance uncertainty may pose operational challenges for power systems. This study proposes a degradation-aware, two-layer framework that jointly eva...

Association of Baseline Serum DKK-1 Levels with Subsequent Bone Metastasis in Stage III Breast Cancer

Background and Objectives: Bone metastasis is the most frequent site of distant spread in breast cancer, yet reliable biomarkers capable of identifying patients at increased risk before metastatic disease becomes clinically evident remain limited. We investigated whether baseline...

The Effect of Emotional Freedom Techniques on Death Anxiety and Cancer‐Related Anxiety in Patients Undergoing Oncological Surgery: A Randomized Controlled Trial

ABSTRACT This study was conducted to investigate the effect of emotional freedom techniques (EFT) on death anxiety in patients experiencing postsurgery cancer‐related anxiety. A total of 120 oncological surgical patients were randomly allocated to either the intervention group (...

Melatonin and vitamin E attenuate acetamiprid induced hepatic injury in male mice

Acetamiprid (ACMP), a neonicotinoid insecticide widely used in agriculture, induces systemic toxicity via oxidative stress. This study investigated the potential protective effects of Melatonin (Mel) and Vitamin E (Vit E) against ACMP-induced hepatotoxicity using biochemical, his...

Comparative Seismic Assessment of Historical Buildings with Similar Typologies Following the 2023 Kahramanmaraş Earthquakes

Historical buildings with similar typological features exhibited different damage levels during the 6 February 2023 Kahramanmaraş earthquakes. Typological similarity refers to the common characteristics of the buildings in terms of construction period, regional construction tradi...

Diagnostic concordance of remote WSI-based thyroid cytology compared to conventional cytological diagnosis: a pilot study

Abstract Background Whole slide imaging (WSI) has emerged as a key component of digital pathology, enabling remote diagnostics and standardized evaluation. However, its diagnostic concordance in thyroid cytopathology, particularly under real-world conditions, remains insufficient...

The Relationship Between the Remnant Cholesterol Inflammation Index and Coronary Collateral Circulation in Patients with Chronic Total Occlusion

Background and Objectives: Although chronic total occlusion (CTO) often presents with varying degrees of coronary collateral circulation (CCC), the biological factors accompanying inadequate collateralization are not fully established. The Remnant Cholesterol Inflammation Index (...

Longitudinal Change and Tracking of Health-Related Physical Fitness in Adolescents Aged 12–16 Years: A Structured Narrative Review

Background/Objectives: The period between 12 and 16 years of age coincides with peak pubertal change, declining habitual physical activity, and the consolidation of lifelong behavioral patterns, making it a critical window for understanding how fitness develops and how stable (or...

The effects of psychoeducation-supported breathing and relaxation exercises on Post-Traumatic stress symptoms and sleep quality in earthquake survivors

This study aimed to evaluate the effectiveness of psychoeducation-supported breathing and relaxation exercises on post-traumatic stress symptoms and sleep quality in individuals affected by the February 6, 2023 earthquakes in Türkiye. While such interventions have shown promise i...

The Influence of Xanthan Gum and Guar Gum Biopolymers on the Geotechnical Properties of Three Different Soils

This study investigates the macromolecular interaction mechanisms between linear-anionic xanthan gum (XG) and branched-nonionic guar gum (GG) biopolymers in three mineralogically distinct soils: Bentonite Clay (BC), Zeolite Silty Soil (ZS), and Red Clay (RC). Mıxtures were prepar...

Innovative active edible coating with safflower (Carthamus tinctorius L.) extract for microbial inactivation and shelf life extension of cheese

<title>Abstract</title> Edible coatings enriched with bioactive compounds represent a sustainable alternative to synthetic preservatives, offering both microbial safety and extended shelf life. This study introduces an active edible coating system based on whey protein isolate (W...

Epicardial Fat Thickness and Nighttime Systolic Blood Pressure Variability in Healthy Young Adults

Abstract Background We recognise epicardial fat thickness (EFT) as a biomarker for cardiometabolic risk and blood pressure variability (BPV) as an independent risk factor for cardiovascular morbidity. While studies link them in hypertensive patients, data for healthy young adults...

Effects of Intravitreal Anti-VEGF Therapy on Conjunctival Flora and Antibiotic Resistance in Age-Related Macular Degeneration

Background: Age-related macular degeneration (AMD) is a leading cause of visual impairment among older adults. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents are widely used for neovascular AMD; however, their potential effects on the conjunctival microbi...

Seminal Plasma Kisspeptin‐1 and Kisspeptin‐54 Levels Are Associated With Semen Parameters and Oxidative Stress in Male Infertility

ABSTRACT Objective Kisspeptin‐1 and Kisspeptin‐54 are key regulators of the hypothalamic–pituitary–gonadal axis and may play a role in male reproductive function. This study aimed to evaluate the association between seminal plasma kisspeptin levels and male infertility, and to ex...
