Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Advanced AlGaAs/GaAs Heterostructures Grown by MOVPE
AlGaAs/GaAs heterostructures are the base of many semiconductor devices. The fabrication of new types of devices demands heterostructures with special features, such as large total thickness (~20 μm), ultrathin layers (~1 nm), high repeatability (up

The Stress Mechanism of Zinc on the Wheat
To investigate the stress mechanism of zinc on the wheat, different concentrations of zinc were used to treat wheat, and the ultrastructure of mesophyll cells of wheat was observed by transmission electron microscope (TEM). The results showed that at the tillering stage, the number of chloroplast decreased, and the thylakoid of chloroplast of mesophyll

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...
