A. M. El-Sayed - NARA Discovery

Strawberry ( Fragaria × ananassa Duch.) is a high-value global crop, yet its productivity is severely constrained by the two-spotted spider mite, Tetranychus urticae Koch. Developing localized economic thresholds is a cornerstone of sustainable Integrated Pest Management (IPM) to mitigate yield losses and reduce acaricide reliance. This two-season field study (2019–2020) investigated the quantitative relationship between T. ur...

Immunometabolic reprogramming in multiple sclerosis: from pathogenic amplifier to therapeutic target in neuroinflammation and remyelinationNARA Subscribed

Inflammopharmacology · 2026 · Springer

Ghada A. Badawi; Rehab M. El-Sayed; Mohamed N. Fawzy

Multiple sclerosis (MS) has conventionally been considered a prototypical autoimmune disorder. While modern immunotherapies effectively control relapsing conditions, they fail to avert progressive neuroinflammation, neurodegeneration, and remyelination failure. This review offers an evidence-based recontextualization. The pathogenesis of multiple sclerosis is multifactorial, resulting from the interaction of genetic predisposi...

This study aims to investigate the effect of milling on the natural radioactivity of Egyptian zircon sand, focusing on the gross alpha (α) and goss beta (β) activity concentrations, with additional evaluation of calcination and sulfuric acid leaching. Zircon samples were milled for different durations, and their gross α and gross β activity concentrations were measured using an ATOMTEX AT1329 sample counter. The measurements s...
