Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is a chronic, systemic, inflammatory condition of unknown etiology. Histopathologic examination is the key to diagnosis of IgG4-RD. The histopathologic features of IgG4-RD are lymphoplasmacytic infiltration, storiform fibrosis, and obliterative phlebitis. As for fewer than 15 years, IgG4-RD has been recognized as a unified diagnostic entity. CD4+ T and B cells, which likely cause organ damage and disabling tissue fibrosis, constitute the major inflammatory cell population in patients with IgG4-RD...

Porphyromonas gingivalis (P. gingivalis) and nicotine have been implicated as a major pathogen in the development and progression of periodontitis. One of the possible mechanism is via the oxidative stress of human periodontal ligament fibroblasts (PDLF) which lead to the damage of cell viability and function. This study aimed to investigate oxidative stress (OS) levels in the cultured media of human PDLF under the induction of P. gingivalis lysate and nicotine. Primary PDLF was cultured in growth media under P...

REVIEW
Mounir Ghabriel, Kojiro Takezawa, Grant Townsend
This article, for both researchers and clinicians, presents an overview of the lingual nerve and highlights how new insights into human anatomical variability can be gained by integrating fine dissection of cadavers with neuroanatomical approaches, microscopic studies, and morphometric techniques. Textbooks mainly provide descriptions of the typical or common gross anatomical appearance of structures in the human body with little reference to the nature and extent of variation that may be encountered within and between populations...
