Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

Smart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

Metastatic prostate cancer recurrence within a percutaneous computed tomography guided needle biopsy tract: A rare case report

UroPrecision, EarlyView.
Abstract Background Metastatic prostate cancer tumor seeding within a percutaneous biopsy tract is rare. While reports of tumor seeding following perineal and transrectal prostate biopsies exist, no cases of prostate cancer tumor seeding along a metastatic percutaneous bone biopsy tract detected by prostate specific membrane antigen (PSMA) positron ...

Timing for Radiotherapy Initiation After Dental Extraction and Risk of Osteoradionecrosis in Head and Neck Cancer Patients: A Systematic Review and Meta‐Analysis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Head and neck cancer (HNC) patients are advised to undergo dental extraction of teeth with poor prognosis prior to radiotherapy (RT) initiation to prevent osteoradionecrosis (ORN). However, insufficient healing time may result in persistent extraction wounds during RT, which constitute a potential risk factor for ORN, whereas ...
