Antimicrobial and anti-inflammatory activity of Cystatin C on human gingival fibroblast incubated with .

Background: Periodontal disease is considered one of the most prevalent chronic infectious diseases, often leading to the disruption of tooth-supporting tissues, including alveolar bone, causing tooth mobility and loss. is considered the major etiological agent of this disease, having a plethora of virulence factors, including, lipopolysaccharides (LPS), hemolysins, and proteinases. Antimicrobial peptides are one of the main components of the innate immune response that inhibit the growth of .

Bioinformatic Analysis for Mucoepidermoid and Adenoid Cystic Carcinoma of Therapeutic Targets.

Unlabelled: Salivary gland neoplasms are a heterogeneous neoplasm group, including mucoepidermoid carcinoma (MECa), adenoid cystic carcinoma (AdCC), and many others.

Objective: We aimed to identify new critical genes of MECa and AdCC using bioinformatics analysis.

Methods: Gene expression profile of GSE153283 was analyzed by the GEO2R online tool to use the DAVID software for their subsequent enrichment.

Multiple approaches to oral epithelial dysplasia degree analyses: a pilot study.

Background: Oral epithelial dysplasia (OED) is the presence of cells of an abnormal type within a tissue, which may signify a stage preceding the development of cancer. Our aim was to determine the interrelation between the expression of multiple molecular markers and the histological features of oral dysplasia.

Methods: Fifteen samples of OED (five for each severity degree) were analyzed through software assisted image cytometry nuclear morphology.

Epstein-Barr virus-positive ulcer in the oral cavity.

Epstein-Barr virus-positive ulcer (EBV + U) is a recently reported B cell lymphoproliferative disorder in the oral cavity, oropharynx, gastrointestinal tract and skin, principally in immunosuppressed patients. A 53-year-old female patient with rheumatoid arthritis treated with methotrexate, presenting ulcers of unknown duration on the dorsum and the lateral left border of the tongue. Excisional biopsy, histopathological analysis and histochemical stains for syphilis (Warthin-Starry), mycotic diseases (Grocott silver methenamine), tuberculosis (Ziehl-Neelsen), immunohistochemistry tests for herpesvirus type 8 (CMV), EBV (LMP-1) and DNA extraction for polymerase chain reaction (PCR) assay to CMV, EBV and herpes simplex virus-1 were performed.

Ectodermal and ectomesenchymal marker expression in primary cell lines of complex and compound odontomas: a pilot study.

Background: Odontomas are odontogenic tumors with hamartoma features that are classified as compound or complex. Our objective was to characterize the proliferation of ectodermal and ectomesenchymal profile markers of primary cell cultures of complex and compound odontomas.

Methods: Four samples of compound odontomas (OdCm) and three of complex odontomas (OdCx) were obtained from patients attending the Oral Pathology and Medicine Clinic of the Graduate Dental School, National Autonomous University of Mexico for primary culture generation.

Immunohistochemical patterns in different stromal variants of pleomorphic adenomas: literature review.

Pleomorphic adenoma is the most frequent type of benign salivary neoplasm located in the mouth and is characterized by its significant histopathological diversity. The histogenesis of the pleomorphic adenoma is uncertain; so far several studies suggest that myoepithelial cells are responsible for the variable histomorphology of this type of neoplasm. At times, stroma is the predominant element.

Sialolipoma of minor salivary glands: presentation of five cases and review of the literature with an epidemiological analyze.

Unlabelled: Sialolipoma is rare benign neoplasm arise from salivary glands (majors and minors) characterized by neoplastic adipose tissue with scattered non-neoplastic salivary gland acinus. To date 60 cases (including 5 cases reported in the present paper) have been reported in scientific literature. This article presents 5 new cases of sialolipoma affecting minor salivary glands (MiSG) and additionally reviews and analyzes the previously published cases to assess possible demographical differences between sialolipoma from minor and from major salivary glands.

Vascular leiomyoma of the oral cavity. Clinical, histopathological and immunohistochemical characteristics. Presentation of five cases and review of the literature.

Leiomyoma, a benign neoplasia arising from smooth muscle is an uncommon neoplasia of the oral cavity. The most common histological subtype in the oral cavity is the vascular one. To supplement information on vascular leiomyoma of the oral cavity (VLOC), we present cases of VLOC describing their clinical, histological, and immunohistochemical characteristics.

[Hospital discharges for oral cancer in the Mexican Institute of Social Security, 1991-2000].

A descriptive study based on the secondary analysis of the Unique System of Information database, Subsystem 13 of Hospital discharges to oral cancer of the Mexican Institute of Social Security (IMSS) during the decade from 1991 to 2000, it was considered all the registrations for oral cancer according to the International Classification of Diseases ICD-9. During that time, 8,800 hospital discharges were registered for oral cancer, out of which 64.6% (n = 5682) were men.
