1. Increase of binucleated cells in the oral mucosa: a study on the use of psychotropics by students of a Brazilian institution
RESUMO O objetivo deste estudo foi avaliar a prevalência de uso médico e não médico de medicação psiquiátrica entre estudantes de graduação em Ciências da Saúde de uma universidade pública do Brasil. Outro objetivo foi determinar a frequência de anormalidades nucleares morfológicas na mucosa bucal desses estudantes. Realizou-se um estudo transv

2. Frequência de micronúcleos em células esfoliadas da mucosa bucal de pacientes obesos / Micronuclei frequency in exfoliated buccal cells of obese patients
A crescente incidência da obesidade e suas comorbidades constituem-se em um grande desafio para a saúde no mundo. Além da doença cardiovascular e do diabetes, dados epidemiológicos demonstraram ligação entre a obesidade e diversos tipos de câncer. As alterações citogenéticas tem sido utilizadas como biomarcadores para identificação de danos celu

3. Nuclear anomalies in the buccal cells of calcite factory workers
The micronucleus (MN) assay on exfoliated buccal cells is a useful and minimally invasive method for monitoring genetic damage in humans. To determine the genotoxic effects of calcite dust that forms during processing, MN assay was carried out in exfoliated buccal cells of 50 (25 smokers and 25 non-smokers) calcite factory workers and 50 (25 smokers and 25 n

4. Avaliação dos constituintes e do potencial mutagênico do material particulado oriundo do beneficiamento artesanal da castanha do caju / Assessment of the components and mutagenic potential of particulate matter from artisanal cashew nut roasting
x Despite the social and economic importance of the processing of cashew nuts to Rio Grande do Norte, the production is still carried out artisanally. To collect the almond nut is necessary to roasting. The smoke generated during the burning of the nut has high concentrations of particulate matter (PM) and the PM produced is inhaled daily by families for a p

5. Biomonitoramento genÃtico de indivÃduos expostos ocupacionalmente a pesticidas no povoado Vila Bessa, municÃpio de ConceiÃÃo do JacuÃpe, Bahia / Genetic biomonitoring of individuals occupationally exposed to pesticides in the village Vila Bassa, municipality of ConceiÃÃo do JacuÃpe, Bahia
The high consumption of pesticides in Brazil and all over the world have lead researches to relate this exposition to possible genetic and health damages in rural workers. Studies reveal that cancer is considered a genetic disease, once it results of the mutation accrual in genes involved with control of proliferation and cellular differentiation or mutation

6. Avaliação do estresse oxidativo, genotoxicidade e mutagenicidade em trabalhadores expostos a tintas
Organic solvents and metals, widely used in paints, can lead to DNA damages and reactives species (RS) generation. The aim of this study was to evaluate possibles oxidative, genotoxic and mutagenic damages in 33 male workers exposed for at least six months to paint. To constitute the control group 29 healthy individuals were choosen, without paint exposure,

7. Increased micronucleated cell frequency related to exposure to radiation emitted by computer cathode ray tube video display monitors
It is well recognized that electromagnetic fields can affect the biological functions of living organisms at both cellular and molecular level. The potential damaging effects of electromagnetic fields and very low frequency and extremely low frequency radiation emitted by computer cathode ray tube video display monitors (VDMs) has become a concern within the

8. Evaluation of genotoxicity through micronuclei test in workers of car and battery repair garages
In this study, the micronuclei test (MNT) was applied in exfoliated cells of buccal mucosa, in order to evaluate the genotoxic risk associated with occupational exposure of mechanics, storage battery renovation workers, and car painters. For each individual, 3000 exfoliated buccal cells were analyzed. There was a significantly higher frequency of micronuclea

9. Intracellular Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis in Buccal Epithelial Cells Collected from Human Subjects
The mouth may provide an accessible model for studying bacterial interactions with human cells in vivo. Using fluorescent in situ hybridization and laser scanning confocal microscopy, we found that human buccal epithelial cells from 23 of 24 subjects were infected with intracellular bacteria, including the periodontal pathogens Actinobacillus actinomycetemco

10. Role of specific determinants in mannan of Candida albicans serotype A in adherence to human buccal epithelial cells.
Candida albicans serotype A (C. albicans A) possesses a specific antigen, designated antigen 6, which resides in mannans on the cell surface. To determine the role of the mannan moiety of the C. albicans cell wall in adherence to buccal epithelial cells, we used antigen 6-deficient mutants which had been isolated by screening with an agglutinating monoclonal

11. In vitro inhibition of adhesion of Candida albicans clinical isolates to human buccal epithelial cells by Fuc alpha 1----2Gal beta-bearing complex carbohydrates.
The role of cell surface glycoconjugates as possible adhesion receptors for Candida albicans yeasts on human buccal epithelial cells was investigated by using a quantitative radiometric assay involving 14C-metabolically labeled microorganisms. Various structurally defined soluble glycopeptides and oligosaccharides were tested at a low concentration (1 mg/ml)

12. Fimbria-mediated adherence of Candida albicans to glycosphingolipid receptors on human buccal epithelial cells.
Candida albicans is an opportunist fungal pathogen that has the ability to adhere to host cell surface receptors via a number of adhesins. Yu et al. (L. Yu, K. K. Lee, K. Ens, P. C. Doig, M. R. Carpenter, W. Staddon, R. S. Hodges, W. Paranchych, and R. T. Irvin, Infect. Immun. 62:2834-2842, 1994) described the purification and initial characterization of a f
