Objective. To compare, pre- and post-swallowing therapy, the level of oral intake scale, and the degree of severity of neurogenic oropharyngeal dysphagia. Method. 19 patients with oropharyngeal dysphagia: 10 Post-Stroke adults, aged from 44 years to 76 years (group 1 – G1), and nine children with Cerebral Palsy, aged from two years and five months to 15 years (group 2 – G2). We excluded individuals in the process of spontaneous recovery. We held retrospective analysis of clinical protocols for clinical speech therapy evaluation with classification of the degree of dysphagia severity, applied before and after swallowing therapy. We used the Functional Oral Intake Scale - FOIS to assess the level of oral ingestion, pre and post-swallowing therapy. Results. The degree of commitment of dysphagia was favorable change only in adults, and in FOIS these changes occurred in both groups. Conclusion. There were favorable changes in the degree of impairment of oropharyngeal dysphagia and levels of FOIS, pre and post - speech therapy in stroke, but in ECINP markers used showed no favorable changes should even be reviewed for application in this population. Future studies are needed to investigate the variables in this sample.

O diagnóstico genético pré-implantacional de embriões equinos já é uma realidade nos Estados Unidos e Argentina. Embora o Brasil seja líder mundial de transferência de embriões equinos, essa tecnlogia ainda está em fase de desenvolvimento, com poucos grupos atuando nessa área no país. O objetivo do presente projeto foi desenvolver a metodologia de micromanipulação e identificação do sexo de embriões equinos a campo. Dessa forma, selecionamos sequências específicas para padronização laboratorial dos ensaios de PCR com amostras de DNA da espécie equina. Os primers que apresentaram maior sensibilidade foram selecionados para a realização da PCR em biópsias embrionárias. Além das análises de biologia molecular, foi desenvolvida a técnica de micromanipulação de embriões equinos. Foram realizadas 105 biópsias de embriões pela técnica de microaspiração, permitindo a identificação do sexo pela técnica de WGA (Whole Genome Amplification) e posteriormente PCR seguido de eletroforese. Os embriões sexados foram transferidos para receptoras sincronizadas, permitindo a avaliação da taxa de concepção dos embriões submetidos à biópsia. Além disso, um embrião foi biopsiado, vitrificado e sexado. Após a identificação do sexo (fêmea) o embrião foi desvitrificado e transferido em receptora criteriosamente selecionada, resultando em prenhez

Patients are looking for esthetic and functional changes when seeking orthodontic treatment and expect the remaining of a stable occlusion. Occlusion stability is one of the goals of the orthodontist; however, dental relationships changes in long-term can occur leading to a relapse of the treatment. Teeth and shape of arches tend to return to the original form, been the retention phase important after the appliance removal, even after several years of post-treatment. This article approaches a submission of a clinical case of Class II division 1 treated with extraction of premolars analyzing its long-term stability.

The objective of this work was to evaluate the effects of the inoculation with plant growth-promoting bacteria on the formation of sugarcane pre-sprouted seedlings, originated from individual buds, and to quantify the initial growth of these seedlings in association with nitrogen application, in a low fertility soil. Two experiments were carried out: one in greenhouse conditions, with a time span of 50 days, and the other in vases under field conditions, with a time span of 180 days. In both experiments, a randomized complete block design was used with a factorial arrangement of 2x3, in the first experiment - with or without inoculation, and with three quantities of bud reserve -, and of 2x2x4, in the second one - with or without inoculation, with or without nitrogen, evaluated in four times: at 45, 90, 135, and 180 days. The inoculant had effect on the initial growth of the pre-sprouted seedlings, increasing sprouting speed and dry matter accumulation on roots and shoots, regardless of the bud reserve amount. In the second experiment, the inoculant increased the initial growth of shoots and root system up to 180 days after transplantation, increasing height, tillering, stalk diameter, dry matter production of stalks and straw, and root length, regardless of nitrogen application. The inoculant has a positive physiological effect on plant growth.

The development of the domestic mammals’ stomach is a complex process, especially in ruminants. The objective of this research was to perform the analysis of structures of this organ during prenatal period. Samples of Nelore fetuses rumen (Bos Taurus indicus) were divided into five groups: 1 - fetuses with 9 to 15 weeks (8 to 21cm) of gestation, 2 - fetuses with 16 to 22 weeks (23 to 37cm), 3 - fetuses at 23 to 29 weeks (40 to 58cm) 4 - fetuses with 30 to 36 weeks (61 to 77cm) and 5 - fetuses with 37 to 43 weeks (79 to 88cm). Sections were stained with Hematoxylin and eosin and Mallory's trichrome and examined at light microscope. In group 1, in fetuses with 11 cm, could be seen all the layers, mucosa with high epithelium and light cells, lamina propria fused with submucosa, the muscular layer was with two thin sublayers similar in thickness and serosa was thin too. With 13.5 cm, was observed the first irregularities in the mucosa with epithelium projections and lamina propria that will lead rumen papillae. With 16.5 cm there was differentiation of the lamina propria to the submucosa. In group 2, in fetuses with 28 cm were observed complete papillae. From this stage, the remaining groups, there was an increase in thickness of the epithelium, lamina propria, submucosal and muscular layer whit the inner sublayer more thicker than the external and serosa. It was concluded that the main variations occur in fetuses of groups 1 and 2, and after this phase, there is increased in thickness of all layers until the end of the pregnancy period.

Introduction: Early childhood is an essential phase of life for the future of oral health. The link between educational and health sectors can facilitate incorporating educational and preventive oral health practices in daily teaching in pre-schools. The main measure is manual tooth-brushing, which is the most accessible method for most of the population. Objective: The objective of this study is to evaluate macroscopically the wear on the bristles, form of storage, and identification of tooth brushes. Material and method: 345 toothbrushes used by children between the ages of 2 and 5 were evaluated in 4 pre-schools, by 2 participants from the oral health program. The Rawls et al. index was used to evaluate the bristles. Result: There were statistically significant differences (p = 0.020 - Mann-Whitney U test) between the frequency of toothbrushes, with the highest being (n = 205) stored at participating school; and, between adequate and inadequate brushes (p < 0.05 - X2 test) with 31.7 and 60%, respectively, classified as unfit for tooth-brushing. Of the toothbrush holders evaluated 100% were used collectively. Regarding identification, 18% of the toothbrushes were not identified in participating schools, and 37% in the others. Conclusion: The toothbrushes exhibited marked wear, and storage was inadequate; however, the schools participating in the oral health program showed toothbrushes with bristles less worn. It is suggested that training of educators regarding correct storage and evaluation of toothbrushes for wear of the bristles should be undertaken in all early childhood schools.

OBJETIVO: A cirurgia de revascularização miocárdica (CRM) na fase aguda do infarto do miocárdio (IAM) está associada a aumento do risco operatório. O objetivo do estudo foi determinar fatores preditores de mortalidade intra-hospitalar nos pacientes submetidos a CRM no IAM. MÉTODOS: Durante três anos, todos os pacientes submetidos a CRM no IAM foram analisados retrospectivamente, utilizando o banco de dados institucional. Sessenta variáveis por paciente foram avaliadas: 49 variáveis pré-operatórias provenientes dos escores 2000 Bernstein-Parsonnet e EuroSCORE; 4 variáveis pré-operatórias não consideradas por esses escores (tempo entre o IAM e a CRM, valor máximo de CKMB, valor máximo de troponina e supradesnivelamento do segmento ST) e 7 variáveis intraoperatórias [uso de circulação extracorpórea (CEC), tempo de CEC, tipo de cardioplegia, endarterectomia, número de enxertos, uso da artéria torácica interna e revascularização completa]. Análise univariada e multivariada para o desfecho mortalidade intra-hospitalar foram realizadas. RESULTADOS: O tempo médio entre o IAM e a CRM foi de 3,8 ± 3 dias. A mortalidade global foi 19%. Na análise multivariada: idade > 65 anos [OR 16,5 (IC 1,8-152), P=0,013]~ CEC >108 minutos [OR 40 (IC 2,7-578), P=0,007], creatinina > 2 mg/dl [OR 35,5 (IC 1,7-740), P=0,021] e pressão pulmonar sistólica > 60 mmHg [OR 31(IC 1,6-591), P=0,022] foram preditores de mortalidade intra-hospitalar. CONCLUSÃO: Variáveis pré-operatórias clássicas como idade > 65 anos, creatinina > 2 mg/dl e pressão pulmonar sistólica > 60 mmHg foram preditoras de mortalidade intra-hospitalar nos pacientes operados de revascularização miocárdica na fase aguda do infarto.
