BURNOUT: analisando a síndrome do ramo das indústrias alimentícias do Rio Grande do Norte

This paper aims to verify the Burnout´s possibilities of incidence, finding the creating dimensions and comparing with the socio-demographics characteristics of the researched professionals. This quantitative-descriptive search has a population of 197 workers of 23 nourishing companies in Rio Grande do Norte. This population is predominantly male, younger than 28 years old, single, relatively instructed (57,07% with complete high school) and having just started their current job since 79% of the interviewees are in the company less than six years. The AUDITORIA DO SISTEMA HUMANO (ASH) model, utilized for investigation and developed for the Spaniards Quijano and Navarro in 1999, has several dimensions about human resources management and the organizational effectiveness, but only makes part of the research in 19 questions Burnout referring. It was used factorial analyses with extraction method, varimax rotation and Kaiser normalization with the intuition to define the creating dimensions of the syndrome, they were evaluated with Cronbach Alpha coefficient after extraction. The dimensions found through the factorial analyses were: emotional exhaustion, physical exhaustion and vitality. The accumulated explanation value reached 65,30% of total variation. The data socio-demographics don t justify the syndrome appearance, because the T test and ANOVA showed irrelevant values. It has been also observed that the founded dimensions were different of the Maslach sociopsychological perspective (emotional exhaustion, depersonalization and low professional realization) allowing comparison with others researches and the possibility to develop new ones with workers from different assistance areas. These new researches are important, since the syndrome refers to chronic labor stress consequences and any professional is favorable to Burnout, harmful to the company as to the collaborators

A satisfação dos clientes internos e o comprometimento organizacional: um estudo à luz do modelo ASH nas indústrias alimentícias do RN

Currently the organizations are passing for continuous cycles of changes due to necessity of survival in the work market. The administration of the future points a way to the organizations of today and tomorrow, the search of the competitiveness from loyalty and motivation of its staff. Of this form, the model of the Auditoria do Sistema Humano (ASH), developed for Spanish researchers and that now it is being applied in Brazil, contemplates a series of dimensions about Human Resources management quality in the companies and the organizational effectiveness, such as the environment where the company is inserted, the strategies, the organizational drawing, the psychological and psychosocial processes, e the reached results. In this direction, the present research analyzed the factors of job satisfaction and organizational commitment, making, also, a relation of causality between the same ones. The quantitative-descriptive research had as population the employees of twenty three nourishing industries of the State of Rio Grande do Norte (Brazil), registered in the Federacy of the Industries of the state. The collection of the data occurred for the months of October of 2005 and March of 2006, by means of the application of questionnaire of model ASH. The sample was composed for 197 employees, however it was observed presence of five outliers, that they had been excluded from the analysis of the data. To extract the dimensions of the satisfaction and the commitment and identification the factorial analysis was used, with extraction method of principal components, rotation Varimax and normalization Kaiser. The gotten dimensions had been evaluated with the calculation of the coefficient Alpha of Cronbach. The factorial analysis of the pointers of the organizational commitment and identification had extracted ten factors. Of these, four had gotten significance of the analyses inside: affective commitment, values commitment, continuance commitment and necessity commitment. The result of the analysis of the pointers of job satisfaction indicated four factors: extrinsic, motivations, relation with the friends and auto-accomplishment. To deal with the data the relation between job satisfaction and organizational commitment it was used technique of multiple regression. The correlation between commitment and satisfaction was satisfactory, detaching the affective commitment with bigger index of correlation, followed of the affective one

A problemática da dicotomia contabilística ao nível dos subsídios ao investimento

A globalização dos mercados, articulada com a abertura das fronteiras dentro da União Europeia, e com a diversidade de sistemas contabilísticos, acentuou a necessidade de criar um único sistema contabilístico que fosse aceite internacionalmente e, ao mesmo tempo, que facilitasse o acesso aos mercados de capitais internacionais. O novo Sistema de Normalização Contabilística (SNC) adotado em Portugal é baseado essencialmente em princípios, conduzindo à existência de novos conceitos e à necessidade de incorporar novas formas de entender a contabilidade. Constata-se que os procedimentos contabilísticos impostos pelo SNC, no caso particular da Norma de Contabilidade e Relato Financeiro (NCRF) 22 - Contabilização dos Subsídios do Governo e Divulgação de Apoios do Governo, são mais exigentes e pormenorizados do que os previstos no anterior sistema normativo nacional, em vigor até 31/12/2009. Verifica-se ainda que esta norma, no que diz respeito ao tratamento contabilístico dos subsídios relacionados com ativos, não segue o preconizado na atual International Accounting Standard (IAS), ou Norma Internacional de Contabilidade (NIC) 20 - Contabilização dos Subsídios do Governo e Divulgação de Apoios do Governo. Pretende-se assim analisar as referidas normas, enumerando as suas principais diferenças, e constatar como os outros países da União Europeia contabilizam estes subsídios. The globalization of markets, combined with the opening of borders within the European Union, and the diversity of accounting systems, emphasized the need to create a single accounting system that is internationally accepted and at the same time, improving access to markets international capital. New Accounting Standards System adopted in Portugal is essentially based on principles leading to the existence of new concepts and the need to incorporate new ways of understanding accounting. It appears that the accounting procedures required by the SNC, particularly in the case of NCRF 22 - Accounting for Government Grants and Disclosure of Government Assistance, are more stringent and detailed than those of the preceding national regulatory system in force until 31/12/2009. It also appears that this standard with regard to the accounting treatment of grants related to assets, does not follow the recommendations in the current IAS 20 - Accounting for Government Grants and Disclosure of Government Assistance. The aim is to analyze the standards, enumerating the main differences, and see how the other UE countries account for these allowances.

Ferramentas Lean na indústria corticeira

O presente projeto tem como objetivo a aplicação de ferramentas do universo Lean Thinking na indústria corticeira de forma a identificar e eliminar fontes de desperdício, criar valor e envolver a organização numa cultura de melhoria contínua focada na satisfação do cliente.

Secretome analysis of Trichoderma atroviride T17 biocontrol of Guignardia citricarpa

The fungal species Guignardia citricarpa is an important pathogen in citriculture. Members of the fungal genus Trichoderma are recognized as biocontrol agents but studies on the interactions between both fungi are scarce. This study aimed to identify extracellular proteins secreted by Trichoderma atroviride T17 that are related to the control of G. citricarpa. Two-dimensional gel electrophoresis (2D) was used to study the patterns of proteins secreted by T. atroviride T17 in medium containing glucose (control) and in medium containing G. citricarpa GC3 inactivated mycelium. We identified 59 of the 116 spots differentially expressed (50.86%) by LC–MS/MS. Of these, we highlight the presence of glycoside hydrolases (CAZy families 3, 43, 54, 76 and 93), chitinase, mutanase, a-1,3-glucanase, a-1,2-mannosidase, carboxylic hydrolase ester, carbohydrate-binding module family 13, glucan 1,3-b-glucosidase, a-galactosidase and Neutral protease 2. These proteins are related to mycoparasitism processes, stimuli and therefore to the biological control of pathogens. The results obtained are in agreement with reports describing an increase in the secretion of proteins related to mycoparasitism and biological control and a reduction in the secretion of proteins related to the metabolism of Trichoderma species grown in the presence of the pathogen. Moreover, these results are pioneer in understanding T. atroviride interaction with G. citricarpa. For the first time, we identified potential candidate proteins that may have a role in the antagonism mechanism of G. citricarpa by T. atroviride T17. Thus our results shed a light into the molecular mechanisms that T. atroviride use to control G. citricarpa.

Construction Innovation Futures - Industry and Environmental Opportunities.

During the next two decades global construction investment will top $100 trillion (US). New directions in construction innovation will be driven by industry to address challenges in skills, environmental regulations and maximise the benefits of low carbon building systems. Growth productivity catalysts such as offsite construction, higher BIM levels and multi-skill operatives will be instrumental contributors in achieving some of these aims. The increasing use of timber architecture across domestic, public and commercial buildings also opens new pathways. This event will discuss some of the key changes taking place in the UK and parallels with Hong Kong’s ambitions towards delivering a sustainable legacy in this sector.

Telomeres in aging and disease: lessons from zebrafish

Age is the highest risk factor for some of the most prevalent human diseases, including cancer. Telomere shortening is thought to play a central role in the aging process in humans. The link between telomeres and aging is highlighted by the fact that genetic diseases causing telomerase deficiency are associated with premature aging and increased risk of cancer. For the last two decades, this link has been mostly investigated using mice that have long telomeres. However, zebrafish has recently emerged as a powerful and complementary model system to study telomere biology. Zebrafish possess human-like short telomeres that progressively decline with age, reaching lengths in old age that are observed when telomerase is mutated. The extensive characterization of its well-conserved molecular and cellular physiology makes this vertebrate an excellent model to unravel the underlying relationship between telomere shortening, tissue regeneration, aging and disease. In this Review, we explore the advantages of using zebrafish in telomere research and discuss the primary discoveries made in this model that have contributed to expanding our knowledge of how telomere attrition contributes to cellular senescence, organ dysfunction and disease.

O relato de resultado integral ("Comprehensive Income"): uma revisão da literatura

O presente trabalho tem como objetivo apresentar uma revisão da literatura sobre o relato do resultado integral, quer na vertente das normas que o regulam, quer ao nível da investigação empírica realizada sobre o mesmo. Embora a apresentação do resultado integral esteja vertida nas normas de contabilidade americanas, desde a década de 90 do século XX, a mesma apenas surge nas normas de contabilidade portuguesas em 2010, com a entrada em vigor do Sistema de Normalização Contabilística (SNC). O SNC prevê a apresentação do resultado integral na demonstração de alterações no capital próprio, formato esse que, atualmente, já não é permitido nas normas do Financial Accounting Standards Board e do International Accounting Standards Board. A revisão de literatura efetuada permite identificar, como oportunidade de investigação futura, a análise aos componentes do “outro resultado integral” das empresas que adotam o SNC, no sentido de aferir até que ponto será pertinente a Comissão de Normalização Contabilística repensar a apresentação do resultado integral para estas empresas.

Síndrome Takotsubo após procedimento anestésico em idade pediátrica - um caso clínico

A síndrome Takotsubo (STT) é uma forma adquirida e transitória de disfunção sistólica, cuja apresentação clínica e eletrocardiográfica mimetiza um enfarte agudo do miocárdio. A STT é também conhecida como miocardiopatia de stress, síndrome do «coração partido», balonamento apical, insuficiência cardíaca aguda reversível, miocárdio «atordoado» (forma neurogénica) ou miocardiopatia aguda das catecolaminas. Os autores descrevem uma apresentação rara de STT após procedimento anestésico. Adolescente de 14 anos, sexo feminino, com antecedentes pessoais de enxaqueca hemiplé- gica e quisto pineal, submetida a ressonância magnética (RM) cranioencefálica de controlo. Durante a indução anestésica com propofol verificou-se bradicardia, revertida com atropina, seguida de taquidisritmia ventricular, revertida com lidocaína e murro pré-cordial. Nas primeiras horas de internamento evoluiu para edema pulmonar associado a insuficiência respiratória global por disfunção ventricular esquerda aguda. O ecocardiograma transtorácico mostrou dilatação do ventrículo esquerdo com hipocinesia global e fração de ejeção reduzida (< 30%). O eletrocardiograma revelou taquicardia sinusal persistente e alterações inespecíficas do segmento ST. Os biomarcadores cardíacos encontravam-se elevados (troponina 2,42 ng/ml, proBNP 8248 pg/ml). Foi medicada com diuréticos, IECA, digitálico e dopamina, com melhoria clínica, bioquímica e ecocardiográfica ao quarto dia. Os ecocardiogramas subsequentes mostraram normalização da função ventricular. A doente teve alta medicada com carvedilol, que suspendeu após normalização da função cardíaca e RM cardíaca não ter revelado alterações. Estão descritos poucos casos de STT em idade pediátrica. Alguns são desencadeados por patologia aguda do sistema nervoso central, mas nem todos cumprem os critérios de diagnóstico clássicos. Neste caso, o procedimento anestésico poderá ter desencadeado a STT.

Cyto- and Genotoxicity assessment of manufactured nano cerium dioxide in the A549 cell line

In the past decades the growing application of nanomaterials (NMs) in diverse consumer products has raised various concerns in the field of toxicology. They have been extensively used in a broad range of applications and cover most of the industrial sectors as well as the medicine and the environmental areas. The most common scenarios for human exposure to NMs are occupational, environmental and as consumers and inhalation is the most frequent route of exposure, especially in occupational settings. Cerium dioxide NMs (nano-CeO2) are widely used in a number of applications such as in cosmetics, outdoor paints, wood care products as well as fuel catalysts. For such reason, nano-CeO2 is one of the selected NMs for priority testing within the sponsorship program of the Working Party of Manufactured Nanomaterials of the OECD. In this context, the aim of this study is to assess the safety of nano-CeO2 (NM-212, Joint Research Center Repository) through the characterization of its cytotoxicity and genotoxicity in a human alveolar epithelial cell line. A dispersion of the NM in water plus 0.05% BSA was prepared and sonicated during 16 minutes, according to a standardized protocol. DLS analysis was used to characterize the quality of the NM dispersion in the culture medium. To evaluate the cytotoxicity of nano-CeO2 in the A549 cell line, the colorimetric MTT assay was performed; the capacity of cells to proliferate when exposed to CeO2 was also assessed with the Clonogenic assay. The genotoxicity of this NM was evaluated by the Comet Assay (3 and 24h of exposure) to quantify DNA breaks and the FPG-modified comet assay to assess oxidative DNA damage. The Cytokinesis-Block Micronucleus (CBMN) assay was used to further detect chromosome breaks or loss. The nano-CeO2 particles are spherical, displaying a diameter of 33 nm and 28 m2/g of surface area. The results of the MTT assay did not show any decreased in cells viability following treatment with a dose-range of nano-CeO2 during 24h. Nevertheless, the highest concentrations of this NM were able to significantly reduce the colony forming ability of A549 cells, suggesting that a prolonged exposure may be cytotoxic to these cells. Data from both genotoxicity assays revealed that nano-CeO2 was neither able to induce DNA breaks nor oxidative DNA damage. Likewise, no significant micronucleus induction was observed. Taken together, the present results indicate that this nano-CeO2 is not genotoxic in this alveolar cell line under the tested conditions, although further studies should be performed, e.g., gene mutation in somatic cells and in vivo chromosome damage (rodent micronucleus assay) to ensure its safety to human health.

Avaliação transcricional de Glutationas -transferases em PEIXE-ZEBRA (Danio rerio) e alterações causadas pela exposição á Microcistina-LR

As Microcistinas são heptapeptídios cíclicos produzidos como metabólitos secundários por diferentes espécies de cianobactérias, sendo relevantes pelo seu potencial hepatotóxico. Peixes apresentam estratégias bioquímicas para detoxificar contaminantes ambientais, incluindo a ativação de enzimas de fase II de biotransformação, que incluem as isoformas de glutationa S-transferase (GST). As GST catalizam a conjugação de glutationa reduzida (GSH) com uma variedade de xenobióticos, incluindo as microcistinas. O presente estudo avaliou os níveis transcricionais de quinze isoformas de GST a fim de identificar isoformas possivelmente envolvidas na detoxificação de contaminantes ambientais como a microcistina-LR (MC-LR) em Danio rerio. A técnica de PCR em tempo real (RT-qPCR) foi utilizada para avaliação dos níveis transcricionais, permitindo análise das GST em diferentes órgãos, abundância e a ativação/repressão das isoformas de GST pela exposição à MC-LR. Foram avaliados os possíveis efeitos causados em brânquia e fígado após exposição por 24 hs às concentrações de 5 µg.L-1 e 50 µg.L-1 de MC-LR. Baseado nos scores de estabilidade para oito genes normalizadores, foram selecionados glicose-6-fosfato desidrogenase (g6pdh), β-actina1 e beta-2-microglobulina (b2m); b2m, alfa-tubulina 1 (tuba) e β- actin1; e tuba, b2m e g6pdh, para normalização dos níveis trancricionais de GST para distribuição órgão-específica, abundância e efeito da MC-LR em brânquia e fígado, respectivamente. A avaliação transcricional da distribuição órgão-específica revelou níveis significativos de gstal e gstk1.1 no fígado; gstp1 e gstp2 em brânquia; mgst3a, gstr1, gstm2, gstm33, gstp1, gstp2 e gstk1.1 no intestino; gstm2, gstm3 e gstal no olho e gstt1a e gsta2.1 no cérebro. Considerando os níveis de transcritos para um dado órgão, gstk1.1, gstal, gstp1 e gstt2 foram mais abundantes nos órgãos de detoxificação, tais como o fígado, brânquias e intestino, enquanto gstt1a e gsta2.1 foram mais abundantes no rim. Em brânquia, gsta2.1 e gstt1b foram reprimidas por 5 µg.L-1 de MC-LR e mgst1.1 foi reprimida em 50 µg.L-1 de MC-LR. No fígado, as isoformas gst2.2 e gstp2 foram reprimidas em ambas as concentrações, gstal foi reprimida em 5 µg.L-1, e gstt1a e gstk1.1 foram reprimidas em 50 µg.L-1 de MC-LR. As isoformas gstal, gstr1, gstp1, mgst3a, gstm1, gstm2 e gstm3 não foram alteradas pela exposição a MC-LR. Os resultados obtidos fornecem informações para a escolha de isoformas específicas de GST possivelmente envolvidas na detoxificação/toxicidade de MC-LR, a serem melhores caracterizadas ao nível protéico e também contribui para a escolha de genes normalizadores a serem utilizados em outros estudos da mesma natureza

Childhood Non-Langerhans Cell Histiocytosis – An Atypical Case

Introduction: Histiocytoses correspond to a heterogeneous group of disorders characterized by the proliferation andinfiltration of histiocytes in tissues. For years, many of the histiocytoses where known by numerous names, reflecting the lack of understanding regarding their origin. Case report: A previously healthy, 4-month-old infant presented a cutaneous lesion of progressive growth on his nose since 1 month ago. The mother has a diagnosis of Sjögren syndrome. On examination, there was a firm well-defined erythematous plaque with 30 mm of diameter and raised edges, on the bridge of the nose. At the left cheek, left thoracic region and right arm there were also small erythematous papules with 5 days of evolution. The analytical study showed elevated antinuclear antibodies and anti-SS-A. Histopathological examination confirmed the diagnosis of non-Langerhans cells histiocytosis. Progressively, more annular erythematous papules and plaques appeared scattered over the face, trunk and limbs with spontaneous resolution of the first lesion on the nose. About 2 months after the initial evaluation, all lesions had regressed spontaneously, with normalization of analytical study at one year-old. Conclusion: Many authors believe that the different subtypes of histiocytosis represent only different stages of the same disease. Immunophenotyping of histiocytosis does not always identify the subtype involved, making the occurrence of atypical cases frequent.

The third dimension: new developments in cell culture models for colorectal research

Cellular models are important tools in various research areas related to colorectal biology and associated diseases. Herein, we review the most widely used cell lines and the different techniques to grow them, either as cell monolayer, polarized two-dimensional epithelia on membrane filters, or as three-dimensional spheres in scaffoldfree or matrix-supported culture conditions. Moreover, recent developments, such as gut-on-chip devices or the ex vivo growth of biopsy-derived organoids, are also discussed. We provide an overview on the potential applications but also on the limitations for each of these techniques, while evaluating their contribution to provide more reliable cellular models for research, diagnostic testing, or pharmacological validation related to colon physiology and pathophysiology.
