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 ...
Aryl hydrocarbon receptor overexpression in miniaturized follicles in female pattern hair loss
(Anais Brasileiros de Dermatologia, 2017-01-01) [Artigo]
The etiopathogenesis of female pattern hair loss is still poorly understood. In addition to genetic and hormonal elements, environmental factors could be involved. The aryl hydrocarbon receptor is expressed in keratinocytes ...
Accuracy of routine diagnostic tests used in paracoccidioidomycosis patients at a university hospital
(Transactions of the Royal Society of Tropical Medicine and Hygiene, 2011-08-01) [Artigo]
The identification of appropriate laboratory measures to confirm clinical hypotheses is important in routine paracoccidioidomycosis medical care. The clinical records and laboratory reports of 401 paracoccidioidomycosis ...
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 ...
(Acta Ophthalmologica Scandinavica, 1997-06-01) [Artigo]
Keratoacanthoma is a rapidly growing skin neoplasia that may stabilize or regress spontaneously. We describe here a case of conjunctival keratoacanthoma and comment about the clinical signs and symptoms and pathological findings.
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 ...
