AI Article Synopsis

  • The study aimed to analyze changes in irradiated mandibular bone by examining how bone tissue lesions develop and affect the area.
  • Researchers assessed the vitality of jaw fragments by counting inhabited and empty lacunae, using methylene blue for staining, and compared these results with microradiographic images.
  • A surprising finding was that areas with the most damage had the highest percentages of osteocytes, raising questions about how to minimize complications from radiotherapy and its repair attempts.

Article Abstract

To understand the changes of the irradiated mandibular bone, we tried to define, in space, how the lesions of the osseous tissue appear and involve. We estimated the vitality of the removed jaw fragments by counting the number of inhabited lacunae (I.L.) and empty lacunae (E.L.) in the sections, without previous decalcification, after surface staining with methylene blue. The results, expressed as percentages of the total amount of osteocytes lacunae, have been compared with the microradiographic aspect of the sections. The most paradoxical finding is that the highest percentages of osteocytes appear in the most destroyed areas. As a conclusion, one may wonder how to proceed to avoid the radiotherapy being followed by attempts for repair: attempts which, indeed, are the source of the complications.

Age-induced abnormalities in bone metabolism disrupt the equilibrium between bone resorption and formation. This largely stems from disturbances in bone homeostasis, in which signaling pathways exert a significant regulatory influence. Aging compromises the functionality of the bone marrow mesenchymal stem cells (BMSCs), ultimately resulting in tissue dysfunction and pathological aging.

Aging often triggers dental pulp fibrosis, resulting in clinical repercussions such as increased susceptibility to dental infections, compromised tooth vitality, and reduced responsiveness to dental interventions. Despite its prevalence, the precise molecular mechanisms underlying this condition remains unclear. Leveraging single-cell transcriptome analysis from both our own and publicly available datasets, we identified Ccrl2 macrophages as particularly vulnerable during the early stages of aging.

Multimodal phototheranostics on the basis of single molecular species shows inexhaustible and vigorous vitality, particularly those emit fluorescence in the second near-infrared window (NIR-II), the construction of such exceptional molecules nonetheless retains formidably challenging. In view of the undiversified molecular skeletons and insufficient phototheranostic outputs of previously reported NIR-II fluorophores, herein, electron acceptor engineering based on heteroatom-inserted rigid-planar pyrazinoquinoxaline was manipulated to fabricate aggregation-induced emission (AIE)-featured NIR-II counterparts with donor-acceptor-donor (D-A-D) architecture. Systematical investigations substantiated that one of those synthesized AIE molecules, namely 4TPQ, incorporating a fused thiophene acceptor, synchronously exhibited high molar absorptivity (ε), NIR-II emission, typical AIE tendency, significant reactive oxygen species (ROS) generation, and high photothermal conversion efficiency.

Objective: The goal of a decompressive craniectomy (DC) or a hinge craniotomy (HC), is to treat intracranial hypertension and reduce mortality. Traditionally, the decompression procedure has been performed with cranial bone removal. However, decompression and repositioning the cranial bone, named HC, has been presented as an alternative for certain cases.
