Elevated micronucleus frequency in patients with type 2 diabetes, dyslipidemia and periodontitis

The over-production of reactive oxygen species (ROS) can cause oxidative damage to a large number of molecules, including DNA, and has been associated with the pathogenesis of several disorders, such as diabetes mellitus (DM), dyslipidemia and periodontitis (PD). We hypothesise that the presence of these diseases could proportionally increase the DNA damage. The aim of this study was to assess the micronucleus frequency (MNF), as a biomarker for DNA damage, in individuals with type 2 DM, dyslipidemia and PD. One hundred and fifty patients were divided into five groups based upon diabetic, dyslipidemic and periodontal status (Group 1 - poor controlled DM with dyslipidemia and PD; Group 2 - well-controlled DM with dyslipidemia and PD; Group 3 - without DM with dyslipidemia and PD; Group 4 - without DM, without dyslipidemia and with PD; and Group 5 - without DM, dyslipidemia and PD). Blood analyses were carried out for fasting plasma glucose, HbA1c and lipid profile. Periodontal examinations were performed, and venous blood was collected and processed for micronucleus (MN) assay. The frequency of micronuclei was evaluated by cell culture cytokinesis-block MN assay. The general characteristics of each group were described by the mean and standard deviation and the data were submitted to the Mann-Whitney, Kruskal-Wallis, Multiple Logistic Regression and Spearman tests. The Groups 1, 2 and 3 were similarly dyslipidemic presenting increased levels of total cholesterol, low density lipoprotein cholesterol and triglycerides. Periodontal tissue destruction and local inflammation were significantly more severe in diabetics, particularly in Group 1. Frequency of bi-nucleated cells with MN and MNF, as well as nucleoplasmic bridges, were significantly higher for poor controlled diabetics with dyslipidemia and PD in comparison with those systemically healthy, even after adjusting for age, and considering Bonferroni's correction. Elevated frequency of micronuclei was found in patients affected by type 2 diabetes, dyslipidemia and PD. This result suggests that these three pathologies occurring simultaneously promote an additional role to produce DNA impairment. In addition, the micronuclei assay was useful as a biomarker for DNA damage in individuals with chronic degenerative diseases.

Correlação entre autoestima e grau de severidade da disfunção temporomandibular em sujeitos controle e afetados

INTRODUCTION: Temporomandibular disorders (TMD) have association with psychological manifestations. OBJECTIVE: The aims of this study were to correlate the severity of TMD and the level of self-esteem, and to investigate sex‑related differences. MATERIAL AND METHOD: We evaluated 57 subjects of both gender, with mean age of 20.28 ± 2.07 years, through the Fonseca Anamnesis Index (FAI) and Rosenberg Self-esteem Scale (RSS). Correlations between variables were performed using the Spearman correlation coefficient; comparisons between the genders were performed using the Mann-Whitney test. It was considered a significance level of 5%. RESULT: No differences were found for the comparisons between the gender in the FAI (p = 0.79) and the RSS (p = 0.90). RSS correlates with the FAI in women (p = 0.01), but in men this result does not occur (p = 0.07). CONCLUSION: We concluded that women are more likely to have emotional disturbances resulting from changes in the temporomandibular joint than men.

Contribuição da amplitude de movimento articular do joelho na marcha de crianças com paralisia cerebral espástica

Individuals with spastic cerebral palsy show muscle weakness, difficulties in the control of agonist and antagonist muscles, decreased range of motion and tonus and sensibility alterations, especially in knee joint. These problems can interfere on the performance of functional activities such gait. The aim of this study was to analyze the contribution of knee range of motion on gait of hemiplegic and diplegic children considering their asymmetries. Twelve children, 6 hemiplegics e 6 diplegics from 7 to 12 years of age (age average= 9,5 ± 1,93) took part. Spasticity was assessed by the Ashworth’s Modified Scale and the passive knee range of motion by an eletrogoniometer. The task was to walk on a walkway of 8m long, in their preferred speed, in 6 attempts, been 3 on right and 3 on left sagital planes. Eigth passive markers were bilaterally fixed for the kinematic record. Orthogonally to the walkway, two digital camcorders were assembled on the sagital plane. The fotogrametric procedures were performed by the Dvideow 6.3 software. The Matlab 7.0.1 software was used to filter and to calculate the dependent variables. The U test of Mann- Whitney found differences to the cerebral palsy type for knee extension/hiperextension (U = - 2.943; p= 0.003), knee relative angle at heel contact (U = - 5.992; p= 0.001) and knee range during stride (U = - 4.099; p= 0.001). The Wilcoxon’s test revealed differences according to the asymmetries for the hemiplegics only for the knee relative angle at heel contact (T= - 2.635; p<0.008). The contributions of passive knee range of motion, revealed by the Spearman correlations, for the more afected limb of the diplegics, showed that the knee extension/hiperextension interfere on the cadence, stride duration and step width; the knee relative angle at heel contact change the stride length and duration and cadence; and the...(Complete abstract click electronic access below)

Avaliação dos efeitos dos inseticidas malation e fipronil sobre a viabilidade e regeneração de girardia tigrina (Platyhelminthe, tricladida)

In this study were carried out toxicity tests and the evaluation of sub lethal effects of the insecticides malathion and fipronil, over the test system of Girardia tigrina, using for these analyses a great variety of methods. For evaluation of the lethal concentrations of the products, adult planarians were exposed to several different concentrations. All the tests were carried out in duplicate, maintained on the shelter of the light, on a temperature 24-26ºC and they had the duration of 96h, with observations at each 24h. The results were statically valued by the tests U of Mann- Whitney, Spearman-Karber, ANOVA and Pearson correlation. The effects over the system-test, in the different tested concentrations, varied in accordance with the time of exposition. The EC50 given by the test of Spearman-Karber was of 12,5mg/L for malathion and 13,4mg/L for fipronil. The evaluation of sub lethal effects was composed by analyses of the potential of regeneration; histological, for tissue damage evaluation; d; and the “comet assay”, for DNA damage detection. The specimens split up and exposed to the insecticides demonstrated, between other effects, retardation in development of the regenerative blastema. The histological evaluation has shown that exposed planarians to lower concentrations of the insecticides cause more significant damage against the tissues and some specific cell types. Through the comet assay, significant damages were noticed in the DNA in all the treatments, when compared with the control group. Such damages may result in reproduction and immunity alterations, which reduce the competitive efficiency and, consequently, the survival chances of these organisms.

Testes funcionais, torque isocinético em inversão e eversão e capacidade de reposicionamento articular: um estudo sobre a estabilidade dinâmica do tornozelo

Introdução: A lesão mais comumente encontrada na população ativa é a entorse de tornozelo. Cerca de 40% destes casos continuam a manifestar sensação de instabilidade articular mesmo após a fase aguda da lesão, caracterizando a instabilidade funcional do tornozelo (IFT). A IFT está relacionada com déficits proprioceptivos e redução na capacidade de produção de força e potência muscular. Haja vista que o basquetebol é um esporte com grande incidência de lesões no tornozelo faz-se necessário o entendimento de métodos de avaliação de baixo custo, que possam contribuir para a prevenção deste tipo de lesão em atletas. Objetivo: Nesse sentido, o presente estudo, tem como objetivo identificar os parâmetros de torque, atividade eletromiográfica, senso de reposicionamento articular e a pontuação em teste funcional em jogadoras de basquetebol com tornozelo estável. Correlacionar os valores de torque, atividade eletromiográfica e do senso de reposionamento articular com a pontuação dos testes funcionais em individuos saudáveis. Método: Participaram deste estudo 6 atletas do gênero feminino praticantes do basquetebol com idade entre 18 e 25 anos. As voluntárias realizaram os seguintes testes: torque isocinético concêntrico em inversão (INV) e eversão (EVE) nas velocidades de 60º e 120º, cinco testes funcionais e teste de reposicionamento articular com os ângulos-alvo de 10º e 20º de inversão. Após a verificação da normalidade de distribuição dos dados com o teste Shapiro-Wilk, utilizou-se o teste de Correlação Spearman para verificar a correlação dos testes funcionais com o pico de torque, o sinal EMG e o reposicionamento articular. Resultados: Não foi encontrados resultados esperados no estudo, exceto na correlação negativa para os valores de RMS do TA na velocidade de 120º nas contrações isocinética...(Resumo completo, clicar acesso eletrônico abaixo)

Avaliação da produtividade no trabalho organizado em turnos em uma empresa vidreira

Work organized in shifts, either for technological, social or economic imposition, allows the best use of means of production, increasing the overall productivity of the enterprises. At the same time, this type of work harms the individual productive capacity of workers, particularly those involved in the night shift. The objective of this work was to assess the behaviour of production in a continuous line and subjected to work organized in shifts. Through the statistical method of analysis of variance, Spearman's test and Tukey's method, was analysed the distribution of the productivity index measured in three fixed shifts of work in a glass company. The productivity index, provided by the integrated management system of the company, refers to the ratio of actual productivity to total productivity. The statistical analysis shows that factors of production, such as allocation of workers, do not interfere with productivity, showing an unexpected pattern, where the average productivity for the three shifts are close and the correlation between the number of workers on the line and productivity is low. The conditions of production had an adverse work environment with exposure to noise, heat, vaporized mist of lubricating oil and risk of accidents. The findings show that the calculation of productivity in use is limited and its use in company’s production control may produce distortions. It is proposed to examine alternative calculations methods that consider the overall productivity

Efeitos do treinamento com pesos nas atividades de vida diária básicas e instrumentais de pacientes com doença de Alzheimer

The Alzheimer's disease (AD) is a neurodegenerative and progressive disease, mostly seen in elderly people, characterized by memory loss. This commitment leads causes deficits in functional capacity, compromising the individual in execution of activities of daily living, like dressing and bathing. This study, with a longitudinal character, aimed analyze the effects of a protocol of weights training (WT) in global cognitive status and realization of activities of daily living (ADL´s) basic and instrumental in AD patients, comparing the effects of four months of WT in the performance of ADL´s in global cognitive status. And also aimed to verify the possible relations between ADL's and global cognitive status of patients before and after the experimental period. The study included 24 patients with clinical diagnosis of AD, divided into two groups: a) training group (TG) consisted of 13 patients who underwent a protocol of WT b) Social Gathering Group (SCG) consists of 11 patients participating in a protocol of social gathering not systematized with activities of reading, writing and walking. Both protocols lasted four months, being developed in three non-consecutive weekly sessions, lasting 60 minutes each. To quantify global cognitive status and the basic and instrumental ADLs were used, respectively, the Mini-Mental State Examination and the Self Perception of Performance in Activities of Daily Living, along with the battery of tests of Activities of Daily Life of Andreotti and Okuma (1999).
