The Use of Clonidine in Patients With ADHD and Comorbid ODD

Background Attention-deficit/hyperactivity disorder (ADHD) co-occurs with oppositional defiant disorder (ODD), which lacks an approved treatment. Clonidine, an alpha-2 agonist approved for ADHD, is used off-label to target aggression, impulsivity, and hyperactivity, though eviden...

Thermal Decomposition Behaviour of Ethylene-Vinyl Acetate from End-of-Life Monocrystalline Solar Panels Under Slow Pyrolysis Treatment

This study investigated the low-temperature thermal treatment of EVA encapsulant from an end-of-life 180 Wp monocrystalline PV panel while evaluating the preservation of recovered crystalline silicon. TGA showed that EVA underwent major decomposition between approximately 330 and...

Europium Oxide Disrupts Metabolic Homeostasis and Antioxidant Defenses in African Catfish ( Clarias gariepinus ): Integrated Physiological and Molecular Docking Approaches

ABSTRACT Chemical pollution from rare earth elements (REEs) has emerged as a significant threat to the stability of freshwater ecosystems. Among these elements, europium oxide (Eu 2 O 3 ) is widely used across various industrial sectors; however, its specific impacts on fish phys...

Automated cloud-edge cyber-physical IoT infrastructure for optimizing the agricultural water-energy nexus and yield

Abstract Global agriculture faces increasing challenges associated with water scarcity and the growing demand for energy-efficient irrigation management. This study developed and evaluated an integrated three-layer cloud-edge cyber-physical Internet of Things (IoT) infrastructure...

Cluster-aware imputation: a hybrid XGBoost-based model for missing data

Abstract The fast growth of high-dimensional datasets in computational biology, industrial IoT, and socio-economic research has made the issue of missing data more challenging. This common problem reduces statistical power and introduces systematic bias in later machine learning...

Transitional High-Al to Intermediate-Cr Podiform Chromitites from Wadi Zikt (Khor Fakkan Block, United Arab Emirates): Evidence for Reactive Melt Percolation during Nascent Forearc Evolution

Abstract Podiform chromitites at Wadi Zikt in the Khor Fakkan Block of the United Arab Emirates constitute a previously undescribed occurrence within the mantle section of the Semail ophiolite. We combine field relations, electron-probe microanalysis, in situ LA–ICP–MS mineral an...

A cell-free therapeutic strategy using MSC-derived exosomes and activated platelet lysate for acute kidney injury induced by rhabdomyolysis

Abstract Rhabdomyolysis-induced acute kidney injury (AKI) is primarily driven by myoglobin-mediated tubular toxicity, leading to pronounced oxidative stress, inflammation, and apoptosis. Given the limited availability of effective targeted therapies, this study aimed to evaluate...

Prevalence of gastroesophageal reflux disease and associated risk factors among medical students in the MENA region: a multinational cross-sectional study

Abstract We aimed to assess the prevalence of gastroesophageal reflux disease (GERD) among medical students in Middle East countries and its associated risk factors. A multinational cross-sectional study was conducted among medical students in 8 Middle East countries. GERDQ and G...

Evaluating airline service quality using a Pythagorean fuzzy multi-criteria group decision-making framework

Growing competition in the airline industry has made service quality evaluation an increasingly important yet complex Multi-Criteria Group Decision-Making (MCGDM) problem. Service quality depends on several interrelated attributes, and passenger or expert assessments are often su...

Modeling the prediction of penetration rate of horizontal directional drilling

In the current practice of horizontal directional drilling (HDD), prediction of the penetration rate (PR) is challenging and relies heavily on practitioners’ experience. Prediction of PR is essential for effective planning and cost management of HDD works. A model that engineers...

Cluster headache care gaps among primary healthcare physicians in the Middle East, North Africa, and Türkiye: a multinational study

Cluster headache is one of the most severely disabling primary headache disorders and is frequently associated with diagnostic delay, inappropriate treatment, disability, and substantial psychosocial burden. Because primary healthcare (PHC) physicians are commonly the first point...

The role of repetitive transcranial magnetic stimulation in restoration of post stroke motor power

Abstract Background Stroke causes long-term disability, and rTMS—by modulating cortical excitability and promoting neuroplasticity—may enhance post-stroke motor recovery. Aim To investigate the effect of rTMS on motor outcome in acute ischemic stroke (AIS) patients admitted withi...

Angiotensin-converting enzyme gene polymorphism as an early predictor of diabetic nephropathy in pediatric type 1 diabetes

Abstract Background Diabetic nephropathy (DN) is a severe complication among type 1 diabetic children, often developing silently before clinical detection. Genetic polymorphisms particularly the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene...

Improving the cryo-resistance of Egyptian buffalo semen via chlorogenic acid and rutin supplementation: molecular docking, antioxidant, and anti-apoptotic pathways

Abstract This study compared the antioxidant effects of chlorogenic acid (CGA) and rutin (RU) supplementation in freezing extenders on the cryo-resistance of buffalo spermatozoa. Over eight weeks, 56 ejaculates were collected from seven fertile buffalo ( Bubalus bubalis ) bulls....

Numerical analysis of seismic performance of deep strutted excavation-structure interaction in sandy soil

This research investigates numerically the seismic performance of deep-braced excavation in adjacent to 10-stories building in sandy soil. Non-linear time-history analysis using hardening soil model with small strain stiffness (HS-small) is performed using PLAXIS 2D. Numerical va...

Efficacy of early blood purification on serum inflammatory mediators in severe acute pancreatitis: a systematic review and meta-analysis

Severe acute pancreatitis (SAP) is the most critical form of acute pancreatitis (AP), characterized by a dysregulated systemic inflammatory response that drives early organ failure and mortality. Current management remains mainly supportive. Early blood purification (EBP) has bee...

Knowledge, attitudes, and practices (KAP) toward stroke prevention among hypertensive patients in Egypt: a multicenter cross-sectional study
