Impact of carotenoids on body composition and adipokine hormones: a systematic review and meta-analysis of randomized controlled trials

Carotenoids, a class of antioxidant phytochemicals, have been proposed to influence adiposity and metabolic regulation through modulation of oxidative stress, inflammation, and adipokine secretion. However, clinical evidence remains inconsistent. This systematic review and meta-a...

A comprehensive look at Respiratory Syncytial Virus (RSV): from pathogenesis to prevention

Respiratory Syncytial Virus (RSV) is a formidable respiratory pathogen that particularly affects infants and children. RSV presents with diverse clinical severity, most often causing mild upper airway symptoms but sometimes progressing to severe and potentially fatal lower respir...

A rare presentation of metastatic thymic carcinoma mimicking pheochromocytoma and Von Hippel–Lindau syndrome: a case report

Metastatic thymic carcinoma is a rare and aggressive malignancy that may present with atypical clinical and biochemical features, posing significant diagnostic challenges. We report the first documented case of metastatic thymic carcinoma mimicking both pheochromocytoma and Von H...

Effectiveness of tele-occupational performance coaching in improving occupational performance and executive function in children with attention deficit hyperactivity disorder: a pilot randomised controlled trial

Background/Aims Occupational performance coaching is a family-centred intervention to enhance occupational performance in children. The remote variant, tele-occupational performance coaching, has become a viable option, especially for children with attention deficit hyperactivity...

Body Composition, Nutritional Status, and Dietary Intake in the First 100 Days After Stem Cell Transplantation and Their Link to One-Year Mortality in Leukemia Patients

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment for acute leukemia; however, the first year after transplantation is associated with an increased risk of morbidity and mortality. This study aimed to evaluate changes in nutritiona...

Optimizing the radiolytic degradation of aspirin and acetaminophen in aqueous solutions using a Rhodotron electron-beam accelerator and central composite design

The escalating pollution of limited freshwater resources by ECs represents a critical byproduct of modern industrialization. Pharmaceutical compounds, specifically NSAIDs like ACM and ASP, are frequently detected in aquatic environments because conventional wastewater treatment p...

Stress Evaluation of Indirect Composite Superstructure on Different Copings in CAD-on Technique for Restoration of Titanium Dental Implants—3D Finite Element Analysis

Abstract The aim of the study is to evaluate and compare the stress distribution and total deformation of indirect composite veneered superstructures fabricated using different coping materials—zirconia, biocompatible high-performance polymer (BioHPP), and polyetherketoneketone (...

Neurocognitive training with visual perturbation improves dual-task hop performance in male athletes after anterior cruciate ligament reconstruction: a randomized controlled trial

Returning to sport after anterior cruciate ligament reconstruction (ACLR) carries high re-injury risk and persistent functional impairments. Sensorimotor control changes not addressed by standard rehabilitation may lead to neurological compensations affecting functional performan...
