Sea spray aerosol (SSA) is a complex mixture of natural substances that can be inhaled by coastal residents. Previous studies have suggested that SSA may have positive effects on human health, but the molecular mechanisms and the factors influencing these effects are poorly understood. In this study, we exposed human bronchial epithelial cells (BEAS-2B) to natural SSA samples, collected monthly using quartz microfiber filters mounted on tripods within 15 m of the waterline, with air drawn through pumps, throughout a one-year period at the Ostend coast, Belgium, and measured cellular gene expression changes using RNA sequencing.

Background: The aim of this study was to analyze the histomorphometric findings of autogenous tooth grafting (ATG) for alveolar ridge preservation (ARP), using graft material from extracted teeth. Variations by sex, age and location of extracted teeth, as well as any associated complications, were also assessed.
Materials And Methods: This prospective, single-cohort study was conducted using ATG placed in extraction sockets.

: the mandibular foramen is an essential anatomic landmark in performing various dental and surgical procedures, including inferior alveolar nerve block (IANB). However, its position may vary based on the individual morpho-functional features of the skull and face. This study aims to conduct a personalized assessment of the location of the mandibular foramen in various shapes of skulls, faces, and mandibles.

( ) thwarts innate immune defense mechanisms in alveolar macrophages (AMs) during the initial stages of infection and in recruited bone marrow-derived cells during later stages of infection. However, how protective inflammatory responses are achieved during infection and the variation of the response in different macrophage subtypes remain obscure.

Departamento de Diagnóstico Oral, Área de Semiologia e Patologia Oral, Faculdade de Odontologia de Piracicaba, Universidade Estadual de Campinas (FOP-UNICAMP), Piracicaba, Brazil.
Background: Rhabdomyosarcoma (RMS), a rare malignant tumor, frequently affects pediatric patients, with 35%-40% occurring in the head and neck. This study analyzes the clinicopathologic profile of pediatric head and neck rhabdomyosarcomas from Brazil, Guatemala, Mexico, and South Africa.
Methods: We reviewed 44 cases from 10 Oral and Maxillofacial Pathology services, conducting immunohistochemical analyses of desmin, myogenin, Myo-D1, and Ki67, with quantification via QuPath software.
