The EMT status in the primary tumor of adamantinomatous craniopharyngioma predict postoperative recurrence in children.

Introduction: Adamantinomatous craniopharyngiomas (ACP) are rare epithelial tumors, which by the WHO are classified as non-malignant tumors. Despite radical tumor regression, almost 57% of patients develop a craniopharyngioma recurrence. The pathogenesis of epithelial cancers involves a process called epithelial-mesenchymal transition (EMT), which is involved in tumor progression and its invasion, and the loss of E-cadherin is crucial for this process.

The CD44s Isoform is a Potential Biomarker for Predicting Craniopharyngioma Recurrence in Children.

Adamantinomatous craniopharyngioma (ACP) is an intracranial tumor considered partly malignant due to its ability to infiltrate surrounding structures and tendency to relapse despite radical resection. CD44 is a known stem cell marker in ACP and is upregulated in cell clusters of invasive ACP protrusions; however, the functions of its alternative splicing isoform variants, CD44s and CD44v1-10, have not yet been studied in terms of ACP recurrence, despite their confirmed roles in cancer development and progression. In this study, we first confirmed the difference in total CD44 expression between samples from patients who experienced relapse and those from patients who did not.

Nanometals incorporation into active and biodegradable chitosan films.

This study investigates the effects of incorporating ZnO, TiO2, and colloidal Ag nanoparticles on the antioxidant, antimicrobial, and physical properties of biodegradable chitosan films. The research focuses on addressing the growing demand for sustainable packaging solutions that offer efficient food preservation while mitigating environmental concerns. In this investigation, the physical properties including thickness, water content, solubility, swelling degree, tensile strength, and elasticity of the chitosan films were examined.

Absorbent hygiene products disposal behaviour in informal settlements: identifying determinants and underlying mechanisms in Durban, South Africa.

Background: Within South Africa, many low-income communities lack reliable waste management services. Within these contexts, absorbent hygiene product (AHP) waste, including nappies (diapers), are not recycled, and are often dumped, ending up in watercourses and polluting the local environment. The structural barriers to collection which have been well explored, however the behavioural determinants of safe disposal for AHPs remains poorly understood.
