Heterotopic squamous epithelial inclusion cyst in a cervical lymph node in a child: a case report and literature review.

Background: A squamous epithelial inclusion cyst in a lymph node is a rare heterotopic phenomenon. Heterotopic squamous inclusion cysts in cervical lymph nodes are even rarer, and to date, only 3 such cases have been reported in the literature, none of which have described the ultrasound features. Here, we report a pediatric case, focusing on the ultrasonographic manifestations of the disease and the differential diagnosis of cervical space-occupying lesions in children.

Introduction of cation vacancies and iron doping into TiO enabling efficient uranium photoreduction.

The reduction of U(VI) to U(IV) in wastewater by semiconductor photocatalysis has become a new highly efficient and low-cost method for U(VI) removal. However, due to the weak absorption of visible light led by wide band gap and low carrier utilization rate resulted from the severe electron-holes recombination, the photoreduction performance of U(VI) is limited. Herein, the Ti vacancies and doped Fe atoms were simultaneously introduced into TiO nanosheet (labeled as 4%Fe-TiO) as a highly active and stable catalysis for U(VI) photoreduction.

The clinical value of multimodal ultrasound for the evaluation of disease activity and complications in inflammatory bowel disease.

Background: Inflammatory bowel disease (IBD) has the characteristics of chronic relapse and remission, which makes early diagnosis and effective evaluation of disease activity especially crucial. With the development of ultrasound technology, its role in the diagnosis and treatment of IBD is increasing. This study aimed to explore the value of multimodal ultrasound in the assessment of disease activity and complications in IBD.
