Análise quantitativa dos tecidos gengivais de ratos tratados com fenitoína e ciclosporina

Os aumentos gengivais podem ser decorrentes de reações teciduais a estímulos idiopáticos, patológicos e farmacológicos. O objetivo desse trabalho foi avaliar morfometricamente e estereologicamente a ação da fenitoína (Fen) e ciclosporina (CsA) sobre os tecidos gengivais de ratos. Dez ratos receberam, por via intraperitonial, Fen na dose inicial de 2 mg/kg de peso corporal/dia, aumentando 2 mg a cada duas semanas, durante 60 dias. em outros 10 ratos, administraram-se, por via subcutânea, 10mg/kg de peso corporal/dia de CsA, durante o mesmo período do grupo anterior. Os valores morfométricos e estereométricos dos tecidos gengivais dos ratos tratados com CsA foram significativamente maiores quando comparado com os valores dos tecidos gengivais do grupo tratado com Fen. Esses resultados sugerem que a CsA na dose utilizada é mais eficaz no desenvolvimento do aumento gengival em ratos, podendo estar atuando na proliferação de fibroblastos e no desequilíbrio fisiológico da síntese de fibras colágenas.

Envolvimento do sistema dopaminérgico na sensibilização comportamental ao femproporex

The effects of repeated administration of fenproporex (FEN) on motor activity of rats were studied. FEN-treated group (5.0 mg/kg, i.p., single dose, 7 consecutive days), showed a marked increase in the motor activity of rats, indicating that the drug induced behavioral sensitization. Repeated coadministration of haloperidol prevented the development of sensitization to repeated administration of FEN. Repeated administration of FEN increased also locomotor activity measured in the open field, ratifying the occurence of sensitization. These findings indicated development of sensitization to repeated FEN administration and that the dopamine system might be involved in the mechanism of sensitization.

Assessment of restorative treatment of patients with amelogenesis imperfecta

Purpose: The purpose of this study was to assess restorative treatment outcomes in the mixed dentition of amelogenesis imperfecta (AI) patients and determine the postrehabilitation oral health status and satisfaction of the patients. Methods: Clinical and radiographic examinations were performed on eight AI patients, who had 74 restorations placed in permanent incisors and molars, to allow evaluation of the integrity of the restorations and periodontal status post-treatment. Subjects completed a survey regarding esthetics, function, and sensitivity. Results: Among the 74 restorations evaluated, seven were lost; of the remaining restorations, 31 were posterior, and 36 were anterior. Ten were rated clinically unacceptable. Teeth with stainless steel crowns had a moderate gingival index (mean=2.3) and plaque index (mean=2.0) scores. Widening of the periodontal ligament and pulp canal obliteration were common radiographic findings. Subject's recall of satisfaction regarding esthetics (P=.002) and sensitivity (brushing-P=.03; eating-P=.01) showed a statically significant difference before and after treatment. Conclusions: During mixed dentition, teeth with amelogenesis imperfecta may be restored with conventional treatment modalities. Direct restorations should be considered interim with multiple repairs anticipated. Post-treatment, gingival inflammation and plaque accumulation were observed. Subjects were satisfied with their appearance and reported a decrease of hypersensitivity. © 2013 Publishing Technology.

Determinação de genes mórbidos e drogáveis a partir da construção e análise da rede integrada de interações moleculares entre genes humanos

The discovering process of new morbid genes and new target proteins for drugs have been shown to be very costly and laborious. Having in view cutting costs and speeding up this process, we propose, in this work, a new method to determine the gene druggability score and morbidity score, the probabilities of the protein encoded by the gene have the characteristics that make it a new target for drugs and in case of an alteration in that gene, we observed a phenotype that characterizes a genetic based illness. To determine these characteristics, we built, analyzed and determined the characteristics of the topology of the integrated molecular interactions network among human genes containing physical interactions between proteins, metabolic interactions and interactions of transcriptional regulation, and included other data such as level of gene transcription and cellular localization of the protein encoded by the gene. We tested our model in training sets and achieved results equal or better than the ones achieved by similar methods in the literature. Finally, with the purpose of investigating whether the assigned scores resembles the potential druggabilities and morbities of the previously unclassi ed genes, we looked for evidences in biomedical literature supporting the potential druggability and morbidity status of genes with the 10 highest scores. We found clear evidences for 73% and 90% of potential druggable and morbid genes respectively

A função autor e a crônica esportiva no Brasil: representações da Copa do Mundo em alguns jornais paulistas e cariocas

From the 1990s, Brazilian newspapers began to refer to the convening of different personalities to comment on the World Cup soccer in their sports pages. This article seeks to examine this phenomenon under the notion that the French philosopher Michel Foucault called the “author function” - one that establishes the existence, circulation and functioning of certain discourses within a specific audience.
