Possible association between Carney complex and multiple endocrine neoplasia type 1 phenotypes
(Arquivos Brasileiros de Endocrinologia & Metabologia, 2008-11-01) [Artigo]
Complexo de Carney (CNC) e neoplasia endócrina múltipla tipo 1 (MEN1) são formas de neoplasias endócrinas múltiplas de herança autossômica dominante. O diagnóstico do CNC ocorre quando dois critérios maiores (lentiginose, ...
Oral stomatitis induced by endogenous progesterone: Case report
(Gynecological Endocrinology, 2009-11-09) [Artigo]
Oral stomatitis induced by endogenous progesterone is a rare clinical condition which may be associated with cutaneous involvement. That is probably due to the peak of progesterone production during the luteal phase of the ...
Expression of apoptotic and cell proliferation regulatory proteins in keratoacanthomas and squamous cell carcinomas of the skin
(Pathology Research and Practice, 2008-01-01) [Artigo]
The aim of this study was to investigate the expression of p53, caspase-3, bcl-2, MIB-1, and PCNA to validate more objective methods to differentiate squamous cell carcinoma and keratoacanthoma, as well as to understand ...
Ex vivo biocompatibility tests of regular and white forms of mineral trioxide aggregate
(International Endodontic Journal, 2006-01-01) [Artigo]
Aim: To examine the genotoxicity and cytotoxicity of regular and white mineral trioxide aggregate (MTA) ex vivo by the single-cell gel (comet) assay and trypan blue exclusion test, respectively. Methodology: Aliquots of 1 ...
Absence of DNA damage in multiple organs after oral exposure to fluoride in Wistar rats
(Bulletin of Environmental Contamination and Toxicology, 2006-11-01) [Artigo]
In vitro cytotoxic and non-genotoxic effects of gutta-percha solvents on mouse lymphoma cells by single cell gel (comet) assay
(Brazilian Dental Journal, 2006-12-01) [Artigo]
Chloroform and eucalyptol are widely used in clinical dentistry as gutta-percha solvents. However, these compounds may represent a hazard to human health, especially by causing injury to genetic apparatus and/or inducing ...
Lack of genotoxicity of formocresol, paramonochlorophenol, and calcium hydroxide on mammalian cells by comet assay
(Journal of Endodontics, 2004-08-01) [Artigo]
Formocresol, paramonochlorophenol, and calcium hydroxide are widely used in dentistry because of their antibacterial activities in root canal disinfection. However, the results of genotoxicity studies using these materials ...
Antimicrobial endodontic compounds do not modulate alkylation-induced genotoxicity and oxidative stress in vitro
(Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology, 2006-08-01) [Artigo]
Objective: To investigate if formocresol, paramonochlorophenol, or calcium hydroxide modulate the genotoxic effects induced by the oxidatively damaging agent hydrogen peroxide (H 2O 2) or the alkylating agent methyl ...
Biocompatibility of glass-ionomer cements using mouse lymphoma cells in vitro
(Journal of Oral Rehabilitation, 2006-12-01) [Artigo]
Glass-ionomer cements are widely used in dentistry as restorative materials and adhesives for composite restorations. A number of genotoxicity studies have been conducted using these materials with results conflicting so ...
Expression of cell cycle regulatory proteins in epithelial components of dental follicles
(Journal of Molecular Histology, 2006-05-01) [Artigo]
Dental follicle is a component of tooth germs, which remain adjacent to the crown of unerupted or impacted teeth. Under the influence of pathologic changes, however, dental follicles that possess reduced epithelium can ...
