Basic Science and Pathogenesis.

Background: Tau aggregation is the major cause of several neurodegenerative tauopathies. Tau interaction with other proteins affects the formation of tau aggregates with seeding activity but less is known about its effects on tau-seed properties. Our previous study revealed that Bassoon (BSN), a presynaptic protein, interacts with tau-seed, exacerbating its toxicity in vivo.

Cortical microarchitecture and remodeling-associated gene expression related to oral cancer prognosis.

The objective of this study was to assess the remodeling-associated gene expression in the mandible of patients diagnosed with oral squamous cell carcinoma (OSCC), investigating the cortical microarchitecture, and their influence on disease-free survival (DFS) and overall survival (OS) rates. A total of twenty-four patients who underwent mandibulectomy for OSCC treatment had two bone fragments harvested from the mandible for gene expression (RANK, RANKL, OPG, and SOST), and microarchitecture analysis, including bone volume, surface, mineral density, degree of anisotropy, and fractal dimension. The prognosis of the patients was assessed.

Perspectives on the teaching of Occupational Dentistry according to university curricula in Southeast Brazil.

Introduction: Occupational Dentistry is a specialty recently acknowledged by the Federal Council of Dentistry that seeks to prevent work-related oral health issues. It aims to improve workers' quality of life and promote a more efficient productive development.

Objectives: This study aimed to investigate whether the subject of Occupational Dentistry was included in the curriculum of undergraduate Dentistry courses in Southeast Brazil.
