SUMMARY
Objectives: The aim of this study was to evaluate the effect of proteolytic inhibitors on the bond strength of a universal adhesive system (etch-and-rinse mode) applied to artificial carious and eroded dentin. Methods: Ninety molars were prepared and randomly divided into three groups according to the substrate: N, no challenges; ACD, artificial carious dentin simulation and ERO, artificial erosion simulation with orange juice. All groups were redivided into three subgroups according to the dentin pretreatment: W, water; CHX, 2% digluconate chlorhexidine; and E-64 (trans-epoxysuccinyl-L-leucylamido-[4-guanidino] butane), 5 μM E-64 inhibitor. They constituted a total of nine groups (n=10): N-W, N-CHX, N-E64, ACD-W, ACD-CHX, ACD-E64, ERO-W, ERO-CHX, and ERO-E64. All specimens were restored with Adper Single Bond Universal/Filtek Z250. Beams (0.64 mm2) were obtained and subjected to the microtensile test (μTBS) in a universal testing machine at 0.5 mm/min. The failure mode of the interfaces was determined by optical microscopy (40× magnification). Data were statistically analyzed by three-way analysis of variance and Tukey tests (p&lt;0.05). Results: All individual factors (p&lt;0.0001) and the interaction between substrate and treatment (p=0.0011) and between substrate and time (p=0.0003) were statistically significant. The caries substrate contributed negatively to bond strength. Chlorhexidine reduced bond strength for normal and eroded conditions. Only the normal substrate was negatively affected by time despite the pretreatment. Conclusions: The universal bonding system appears to be a promising bonding strategy for the maintenance of bond strength to affected dentin. E-64 did not affect bonding to the dentin in contrast to the use of chlorhexidine, which, when associated with the universal system, did affect the microtensile bond strength for artificial carious dentin.

A adequada administração financeira de curto prazo é fundamental para que as empresas alcancem um desempenho eficiente e tenham prosperidade. A gestão do capital de giro envolve planejamento e controle de itens do ativo e passivo circulante devendo se primar pela recuperação de todos os custos e despesas que ocorrerem durante o ciclo operacional e pela obtenção do lucro almejado. Devido a limitações do mercado, no Brasil, as empresas utilizam em pequena escala o endividamento de longo prazo tornando como principais fontes de recursos, obrigações para com terceiros de curto prazo e retenção de lucros. Ao se observar o cenário econômico brasileiro, verifica se que o setor siderúrgico tem grande participação no saldo comercial do país e possui referência mundial em relação a produção de aço bruto. A Gerdau S.A e a Companhia Siderúrgica Nacional são empresas de destaque neste setor. Foi realizada a análise comparativa e a avaliação intrínseca das duas empresas em questão, revelando como ambas registram sua administração financeira de curto prazo. Os estudos indicaram que as duas entidades enfrentaram situações distintas entre 2010 e 2012, sendo evidenciado o efeito tesoura em uma das duas comparadas. Na visão geral, tanto a liquidez como a rentabilidade sofreram queda, porém a geração de caixa mostrou-se eficiente.

Authors: Sokovnina Marina Solomonovna , Aleshin Viktor Nikolayevich 
Published: November 2017

Beginning with a comparison of the concepts and methods of psychodrama and transactional analysis, the authors identify similarities and present their experiences of combining these approaches in order to conduct workshops for 5th grade (11-12 years) students within the Russian educational system. They provide their rationale for this work, details of the content of the training and an example of the work of the students in the form of an agreement on cooperation between students and teachers. They provide an analysis of the reported emotions during lessons for 78 students compared to 38 within control groups, showing increased positive emotions and decreased negative emotions for those in the transactional analysis/psychodrama lessons. They conclude that the role-play method used was more effective than traditional educational methods within Russia for the development of autonomy, motivation and involvement of students.
An Investigation using a Case Study Approach into the Impact on a Counselling Team in the UK of an Organisational Restructuring within a Family Support Service
Authors: Robinson Gillian 
Published: November 2017

Following an organisational restructuring of a hospice in the UK, the author has used a case study approach to investigate the impact of this on a team of volunteer counsellors of which she was a member. A small number of the volunteer counsellors completed a questionnaire and some managers and other professionals were interviewed, and summaries of responses through each method are presented. The results are reviewed in terms of several transactional analysis concepts, and the author concludes by hypothesising that the impact of the restructuring on the counsellors appeared to parallel the sense of vulnerability felt by their clients.

Authors: Nagel Norbert , König Joachim , Ottman Sebastian , Hahnle Annika 
Published: November 2017

The authors present the development and statistical analysis, conducted under the auspices of the German Transactional Analysis Association (DGTA), of an online evaluation system of transactional analysis training. The understanding of evaluation research is clarified, and the data-entry form and its grounding in the theory of transactional analysis are presented. Emphasis is placed on the development of the competence concept, the definition of competence categories, and the representation of the foundations of a transactional-analytic educational theory. The scientific examination of the validity and reliability of the scales, the research process with pre-test and re-test, and the evaluation of the data in the system of online evaluation are extensively documented. In conclusion, it is claimed that this online-based DGTA evaluation is one of the few result-oriented teaching evaluation instruments in the German-speaking countries which meets scientific control criteria and is published.Citation - APA format: Nagel, N., König, J., Ottmann, S., & Hahnle, A.

Objective.To evaluate exposure to environmental factors inhaled during pregnancy and after birth until juvenile idiopathic arthritis (JIA) diagnosis among residents of a large city.Methods.This is an exploratory case-control study that consists of 66 patients with JIA and 124 healthy controls matched by age and sex, living in the São Paulo, Brazil, metropolitan area until JIA diagnosis, and whose mothers had resided in this region during pregnancy. A structured and reliable questionnaire (κ index for test-retest was 0.80) assessed demographic data, gestational and perinatal-related factors, and exposure to inhalable environmental elements during pregnancy and after birth (occupational exposure to inhalable particles and/or volatile vapor, exposure to cigarette smoke, and the presence of industrial activities or gas stations near the home, work, daycare, or school). Tropospheric pollutants included particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and carbon monoxide (CO).Results.During pregnancy, intrauterine cigarette smoke exposure (OR 3.43, 95% CI 1.45–8.12, p = 0.005) and maternal occupational exposure (OR 13.69, 95% CI 4.4–42.3, p < 0.001) were significant independent risk factors for JIA diagnosis. In contrast, maternal employment (OR 0.06, 95% CI 0.02–0.2, p < 0.001) and ideal maternal weight gain (OR 0.36, 95% CI 0.2–0.8, p = 0.017) presented negative associations. Secondhand smoke exposure from birth to JIA diagnosis (OR 3.6, 95% CI 1.8–7.3, p < 0.001) and exposure to O3during the second year of life (OR 2.76, 95% CI 1.20–6.37, p = 0.017) were independent and significant risk factors for the pathogenesis of JIA.Conclusion.In our study, cigarette smoke exposure (intrauterine and after birth), exposure to O3in the second year of life, and maternal occupational exposure were identified as potential risk factors for JIA, warranting further study.

Published: November 2017

Objectives:
The aim of this study is to explore the effects on serotonergic system of sertraline in the Sprague–Dawley (SD) rats of myocardial infarction (MI), depression, and depression post-MI.

Methods:
A total of 80 SD rats were randomly allocated into two pretreatment groups, including saline-pretreated group and sertraline-pretreated group. The sertraline-pretreated rats received sertraline and the saline-pretreated rats received saline for the past 4 weeks. Then, the two groups were randomly divided into four subgroups, respectively, including sham, MI, depression, and depression post-MI (MI + depression) subgroup. All animals were then sacrificed after 3 days to observe the effects of sertraline on levels of 5-HT, 5-HT2AR, and SERT in the rat serum, platelet, and brain.

Results:
As compared with saline treatment group, serum 5-HT decreased significantly in sham subgroup and increase significantly in MI, depression, and MI-depression subgroups, platelet 5-HT increased significantly, brain 5-HT decreased significantly in the four subgroups after sertraline treatment (all P < 0.05). As compared with saline treatment group, platelet 5-HT2AR decreased significantly in the sham subgroup and increased significantly in MI and depression subgroups, brain 5-HT2AR increased significantly in MI subgroup and decreased significantly in depression and MI + depression subgroups after sertraline treatment (all P < 0.05). As compared with saline treatment group, serum SERT decreased significantly in the sham subgroup and increased significantly in depression subgroup, platelet SERT decreased significantly in the four subgroups and brain SERT increased significantly in sham and depression subgroups and decrease significantly in MI subgroup after sertraline treatment (all P < 0.05).

Conclusion:
Sertraline regulated 5-HT concentration of peripheral blood and brain according to 5-HT2AR and SERT, thereby regulating the platelet function in various pathological states including MI, depression, and depression post-MI.
