Proteína da matriz do esmalte associada a R.T.G. e vidro bioativo no tratamento de furca grau III em cães

This study investigated, both histologically and histometrically, the efficacy of enamel matrix derived proteins (EMD) associated with bioactive glass (BG) and an absorbable membrane in the treatment of class III furcation defects in mongrel dogs. After surgical defect creation and chronification, the lesions were randomly divided into three groups according to the treatment employed: Test Group 1 - EMD + BG + membrane, Test Group 2 - EMD + membrane and Control Group - BG + membrane. After a 90-day healing period, the dogs were sacrificed. The descriptive analysis and the histometric data showed similar results for the experimental groups in all studied parameters (MANOVA, p > 0.05). The association of Emdogain® with bioglass and GTR, or with GTR only, showed similar results when compared with the ones obtained with bioglass associated with membrane in the treatment of class III furcation defects in dogs. The three modalities of treatment showed partial filling of the furcations, with bone and cementum regeneration limited to the apical portion of the defects.

Uso do grau de preferência alimentar para a caracterizaç ão da alimentação de peixes na APA de São Pedro e Analândia

We studied feeding habits of four fish species in two watershed at APA - Área de Proteção Ambiental (Area of Environmental Protection) in São Pedro and Analândia, State of São Paulo, southeastern Brazil. Feeding Preference Degree (FPD) was used to demonstrate the importance of each food item for the species of both basins. Feeding habits of both species of lambari was variable. The allochtonous items such as insects, autochtonous items, and vegetal material were very important, characterizing omnivory. The bagre (Rhamdia quelen) fed mainly on insects at the Jacaré-pepira Basin and also on fishes at the Corumbataí basin. The cascudo Hypostomus strigaticeps ingested autochtonous vegetal material and sediments at both basins.

Força de compressão e umidade no perfil de dissolução da hidroclorotiazida

The aim of this work was to evaluate the influence of compression force and humidity in the dissolution profile of tablets formulation. As hidroclorotyiazide presents real problems of bioavailability, it was incorporate as standard drug in a formulation of tablets to study the mechanical resistance, time of disintegration and dissolution profile in function of humidity and compression force. The time of disintegration was not affected by the compression force, but it was influenced by humidity. The dissolution profile was altered by the compression force and for the humidity as well. Both factors can alter the bioavailability of drugs dispensed in the form of tablets.

Interação entre grau de perda auditiva e o incômodo com zumbidos em trabalhadores com história de exposição ao ruído

Hearing loss and tinnitus impact the lives of workers in every instance of their lives. Aim: this paper aims to investigate the existence of a dose-response relationship between hearing loss and tinnitus by determining whether higher levels of hearing loss can be associated with increased tinnitus-related discomfort. Materials and method: this cross-sectional case study assessed 284 workers exposed to occupational noise through pure tone audiometry. Test results were categorized as defined by Merluzzi. Individuals complaining of tinnitus answered the adapted and validated Brazilian Portuguese version of the Tinnitus Handicap Inventory. A generalized linear model was adjusted for binomial data to test the interaction between these factors. Results: over 60% of the ears analyzed had hearing loss, while more than 46% of them had tinnitus. Tinnitus prevalence and risk rates increased as pure tone audiometry results got worse. The association between both, considering all hearing loss degrees, was statistically significant. Conclusion: the results point to a statistical association between hearing loss and tinnitus; the greater the hearing loss, the greater the discomfort introduced by tinnitus. 2009 © Revista Brasileira de Otorrinolaringologia.

Grau de dependência de idosos hospitalizados para realização das atividades básicas da vida diária1

This study aimed to identify the level of dependence in elderly inpatients when performing Basic Activities of Daily Living. This quantitative, cross-sectional, descriptive study was conducted in the Adult Ward of the Botucatu University Hospital Emergency Unit - UNESP, Brazil. Data was collected by means of interviews, observation, and individual medical chart consultation, to be analyzed via logistic regression using the statistical software package SAS for Windows, version 9.2. The sample consisted of 71 subjects with a mean age of 74.30 years. It was observed that 30.99% of the older individuals showed to be independent in performing the proposed activities; 22.53% were partly dependent; and 46.48% were fully dependent. Gerontology care must aim at maintaining functional conditions, thus promoting independence and preserving these individuals' dignity.

Variabilidade espacial da resistência mecânica do solo à penetração e umidade do solo em área cultivada com cana-de-açúcar na região de Humaitá, Amazonas, Brasil

The mechanical resistance to penetration (RP) is an attribute indicator of compaction was influenced by soil moisture. The objective of this study was to evaluate the spatial variability of soil resistance to penetration and soil moisture on area under cultivation of sugar cane in the region of Humaitá, Amazonas, Brazil. We conducted a sampling grid of 70x70 m where points were scored at regular intervals of 10 m, a total of 64 points. Soil samples were collected at depths of 0.00 to 0.15 m, 0.15 to 0.30 I 0.30 to 0.45 m for determination of soil moisture and soil resistance to penetration in the field. After analysis of these data analyzes were descriptive statistics and geostatistics. We conclude that all the variables studied showed spatial dependence and range values were higher than stipulated by the sampling grid and the RP and soil moisture showed a spatial relationship where lower values of PR concentrated on smaller values of soil moisture.
