Response-Surface-Guided Extraction and Copper Modification of Nanocellulose from Corn Cob and Hemp Hurds: Source- and Loading-Dependent Structural and Electrochemical Properties

Agricultural residues offer a source of nanocellulose for developing functional composites. This study examined how biomass source, extraction conditions, and copper loading affect the structural and electrochemical properties of nanocellulose derived from hemp hurds and corn cob...

Sodium perborate tetrahydrate modulates neuroinflammation and reduces Leishmania infantum infection in astrocytes

Abstract Leishmaniasis is a neglected tropical disease caused by protozoan parasites of genus Leishmania . Although the parasites are classically considered macrophage-resident pathogens, accumulating evidence suggests that Leishmania can cross the blood–brain barrier and induce...

Frequency-Independent Analog Interference Cancellation with Adaptive Phase Control for Narrowband Receivers

Reliable signal detection in narrowband communication receivers becomes challenging under strong electromagnetic interference. This study presents a frequency-independent, algorithm-supported analog interference cancellation architecture designed to suppress strong interference s...

Objective To evaluate the alveolar and nasolabial changes in infants with complete bilateral cleft lip and palate (CBCLP) with deviated and nondeviated premaxilla following nasoalveolar molding (NAM) and to compare the nasolabial changes induced by NAM with growth changes in heal...

Effect of Simulated Soft-Tissue Edema on Ultrasonographic Detection of Nondisplaced Dentoalveolar Fractures: An Ex Vivo Animal Model Study

Objectives: This single-blinded ex vivo diagnostic accuracy study evaluated high-frequency ultrasonography for detecting nondisplaced dentoalveolar fractures and assessed the effect of simulated post-traumatic soft-tissue edema. Methods: Eighteen fresh sheep heads provided 108 an...

Tissue Transglutaminase (TG2) as a Candidate Biomarker and Potential Therapeutic Target in Endometriosis: Functional Evidence from shRNA-Mediated Downregulation of TG2 in Endometrial Mesenchymal Stem Cells

Background/Objectives: Endometriosis involves the presence of endometrial tissue outside the uterus. Since the migration of endometrial cells is pivotal to lesion development, tissue transglutaminase (TG2)—known for its roles in cell adhesion, migration, and stemness—may play a s...

Real-world outcomes of children with first relapsed acute lymphoblastic leukemia treated according to the ALL-IC REL 2016 guideline in Türkiye

Relapsed acute lymphoblastic leukemia (ALL) remains a major challenge in pediatric oncology, particularly where access to modern immunotherapies is limited. This national multicenter study evaluated real-world outcomes of children with first relapsed ALL treated according to the...

Evaluation of the pSOFA Score in a Pediatric Intensive Care Unit and Its Discriminative Performance Compared with PRISM 4 and PIM 3

Objectives: We aimed to evaluate the performance of the age-adapted Pediatric Sequential Organ Failure Assessment (pSOFA) score, as a predictor of mortality in patients admitted to pediatric intensive care units (PICUs), and to compare it with the Pediatric Risk of Mortality 4 (P...

Suppressing Charge Recombination in DSSCs with ZrO2 Compact Layers: Experimental Validation and Mathematical Modeling

Since their breakthrough development, dye-sensitized solar cells (DSSCs) have emerged as highly promising third-generation photovoltaics; however, interfacial charge carrier recombination remains a persistent bottleneck. This study investigates the application of a wide bandgap Z...

Influence of distal prosthetic extension on structural deviation of metal-acrylic all-on-four prostheses: an in vitro study

The All-on-Four concept rehabilitates the edentulous arch with two anterior axial and two posterior tilted implants, but the segment extending distally beyond the implants may affect its structural accuracy. Limited information exists on how the distal prosthetic extension distan...

Multilevel Analysis of Glutathione-Induced Responses in Pepper Seedlings Under Water-Deficit Conditions

Drought stress is a major abiotic factor that negatively affects plant growth, physiological processes, and yield in pepper cultivation. This study evaluated the ameliorative effects of exogenous glutathione (GSH) at 50 µM and 100 µM in pepper seedlings grown under water-restrict...

Green-Synthesized Mesoporous Silica-Enhanced Herbal Nanofibers with Antimicrobial, Anti-Inflammatory, and Biocompatible Wound Healing Potential

Advanced wound dressings should actively promote tissue repair while preventing microbial infection and excessive inflammation. In this study, multifunctional electrospun nanofibers composed of poly(vinyl alcohol)/chitosan/gelatin were developed by incorporating green-synthesized...

News Headlines as Narrative: Reframing the Israel-Palestine Conflict in English, Turkish and Spanish News Coverage

News translation serves as a pivotal mediating force in the cross-cultural construction of conflict narratives. Particularly in coverage of the Israel-Palestine conflict, reframing proves unavoidable, as translators inevitably reconstruct events to suit new communicative contexts...
