Analysis of glass-based artworks is important for authentication purposes. In recent years, there have been rapid advancements and improvements in the characterization of glass objects using different analytical approaches. The present study presents an interdisciplinary and multi-analytical authentication approach that provides useful tools and markers to unmask possible imitations, counterfeiting, and forgeries in Cultural Heritage glass beads by comparing the composition of historical and modern glass beads.

Osteoporosis, characterized by reduced bone mineral density and increased fracture risk, poses a significant health challenge, particularly for aging populations. Systemic treatments often lead to adverse side effects, emphasizing the need for localized solutions. This study introduces a 3D-printed polycaprolactone (PCL) scaffold embedded with strontium-substituted mesoporous bioactive glass nanoparticles (Sr-MBGNPs) and icariin (ICN) for the targeted regeneration of osteoporotic bone.

Background: Systemic light chain amyloidosis is a rare and debilitating disease, especially for which initially presented with digestive tract involvement. Myocardial amyloidosis is highly aggressive with generally poor prognosis and often resulted in missed diagnosis or misdiagnosis with routine examination tools. Multimodality imaging play an important role in diagnosing the amyloidosis effect on multiple organs.

Article Synopsis
- The study focuses on creating composite films of poly (methylmethacrylate) (PMMA) blended with magnesium oxide quantum dots (MgO QDs) at varying concentrations, and the films were annealed at 130°C for different durations to observe changes in their properties.
- Analysis revealed that the initial crystallinity of the PMMA films decreased with annealing but slightly improved with the diffusion and coalescence of MgO QDs, leading to the formation of larger clusters that influenced the films' structural properties.
- The research highlights the significance of temperature and molecular forces in the evolution of the film's morphology and stability, demonstrating unique energy dissipation mechanisms and the complex interplay of inter- and intra
