Published: September 2015

Aim: to investigate the effect of long-term immobilization-painful stress on ino- and chronotropic functions of the heart with inhibition of various NO-synthases. Materials and methods: 30 female albino rats were taken. Blockers of NO-system were: aminoguanidine (50 mg/kg), 7-Nitroindazole (50 mg/kg) and NG-nitro-L-arginine methyl ester (10 mg/kg). Stress was modeled by suspending the animals for cervical dorsal skin fold for 24 hours. The functional reserves of the heart were studied using adrenoreactivity and isometric load tests. Results: experiments showed that immobilization-painful stress leads to a decrease of cardiac ino- and chronotropic functions which is observed in the reduction of increment dp/dt+, dp/dt-, LVP and HR during load tests in comparison to control group of intact animals. Selective blockade of nNOS with 7-Nitroindazole causes even greater decrease an increment indices of myocardial contractility and LVP in stressed animals during load tests. The most pronounced inhibition of inotropic function of the stressed animal’s heart observed in the non-selective inhibition of NO-synthases by L-NAME. Administration of aminoguanidine to animals (inducible NOS blocker)before and after stress causes an increase of inotropic reserve of the heart, resulting in increased increment of myocardial contractility and relaxation findings, left ventricular pressure and heart rate during load tests. Conclusions: NO-ergic system plays a significant role in limiting of the negative stress effects on the contractile function of the heart.

Aim: to determine the mechanism of food sensitization in children with chronic Opisthorchis felineus invasion. Patients and methods: during the epidemiological study the groups of patients (7–10 years) with chronic opisthorchiasis (n =237) and children without chronic opisthorchiasis (n =496) were formed. The investigation included interviewing of parents / guardians, measurement of total IgE, specific IgE to food allergens and component-resolved diagnostic, real-time PCR in stool samples. Results: the chronic opisthorchiasis invasion in children is associated with reduced risk of food sensitization, compared with non-infected group (9,7 vs 16,94%, OR =0,53; 95% CI 0,31–0,88; p =0,01). Opisthorchiasis of high intensity negatively correlated with increased level of specific IgE to food allergens in serum (OR =0,46; 95% CI 0,24–0,91; p =0,023). The association between level of total IgE and intensity of opisthorchiasis combinated with food sensitization was found. The sensitization to allergens class I (cyp c1, cor a11, gal d2, pru p3) is more prevalent in patients with opisthorchiasis, in uninfected children the sensitization to bet v1-homologues (mal d1, pru p1, cor a1, ara h8) is most common. Conclusions: the epidemiological data on the effect of the Opisthorchis felineus invasion on mechanisms of food sensitization in children were obtained.

Published: September 2015

As it became known recently, in addition to the enzyme (enzymes and/or ribozymes) in living organisms occur a large number of ordinary chemical reactions without the participation of biological catalysts. These reactions are distinguished by low speed and, as a rule, the irreversibility. For example, along with diabetes mellitus, glycation and fructosilation of proteins are observed resulted in posttranslational modification with the low- or nonfunctioning protein formation which is poorly exposed to enzymatic proteolysis and therefore accumulates in the body. In addition, the known processes such as the nonenzymatic carbomoylation, pyridoxylation and thiamiation proteins. There is a reasonable basis to believe that alcoholic injury also realized through parametabolic secondary metabolites synthesis such as acetaldehyde. At the same time, the progress in supramolecular chemistry proves that in biological objects there is another large group of parametabolic reactions caused by the formation of supramolecular complexes. Obviously, known parameterizes interactions can modify the formation of supramolecular complexes in living objects. These processes are of considerable interest for fundamental biology and fundamental and practical medicine, but they remain unexplored due to a lack of awareness of a wide range of researchers.

Sanfilippo syndrome (mucopolysaccharidosis type III) is a lysosomal disorder caused by a defect in the catabolism of heparan sulfate. Mucopolysaccharidosis type III is the most common type of all mucopolysaccharidoses. The pathogenic basis of the disease consists of the storage of undegraded substrate in the central nervous system. Progressive cognitive decline resulting in dementia and behavioural abnormalities are the main clinical characteristics of Sanfilippo syndrome. Mucopolysaccharidosis type III may be misdiagnosed as other forms of developmental delay, attention deficit/hyperactivity disorder and autistic spectrum disorders because of lack of somatic symptoms, presence of mild and atypical forms of the disease. Patients with Sanfilippo syndrome may have comparatively low urinary glycosaminoglycans levels resulting in false negative urinary assay. Definitive diagnosis is made by enzyme assay on leucocytes and cultured fibroblasts. There is currently no effective treatment of mucopolysaccharidosis type III, though ongoing researches of gene, substrate reduction and intrathecal enzyme replacement therapies expect getting curative method to alter devasting damage of central nervous system in near future.

Our understanding of the role of adipose tissue has been completely changed during the past decades. The knowledge of its contribution to endocrine and immune pathways opened the new insights on the pathogenesis and therapy of many diseases and new perspectives for the regenerative medicine. The further researches should be provided to study anatomy and functions of local fat depots in more details. Of the most interest is the orbital adipose tissue due to its origin from the neural crest. This review represents the current data about anatomy, structure, cell composition and biochemistry of orbital fat. The main attention is put to such cell types as adipocytes and adipose derived mesenchymal stem cells. The foreign authors’ findings on such characteristics of stem cells from orbital adipose tissue as CD markers and differential capacity are reviewed. The found evidences of interaction between orbital adipose tissue, eyeball and associated structures allow us to hypothesize that this fat depot may contribute to various ocular pathology. In this paper, we outlined the possible directions for further investigation and clinical application of orbital fat and cells its composing in ophthalmology, reconstructive and plastic surgery and regenerative medicine.

The article presents the data on the structure and mechanisms of β-сatenin functioning. The basic aspects of the role of β-сatenin in malignant transformation have been studied at various tumors. Primary structure of β-catenin allows it to interact with many factors and ligands, including transcription factors, α-catenin, cadherin, Axin, Rho family GTPases, Bcl9 et al. This interaction is the base for β-catenin's intracellular multifunctioning. The review presents data on the participation of β-catenin in the mechanisms of adhesion, regulation of RNA metabolism, formation contacts with the cytoskeleton and its role in the canonical Wnt signaling pathway, marked examples pro-inflammatory and anti-inflammatory effects of β-catenin. The β-catenin involvement in malignant transformation and progression of certain tumors is not in doubt. The data on the changes in β-catenin expression in the given examples of colon cancer, prostate cancer, different forms of thyroid cancer and hepatocellular carcinoma are presented with the prospects of its use as a marker and a predictor of malignant transformation. Continued research in this area will not only make use of β-catenin as a potential predictor of malignant tumors, but also to develop approaches to targeted therapy.

Published: September 2015

ABSTRACTThis study aimed to evaluate the influence of foliar fertilizer doses containing Mn of phenological stages of suggested application in RR soybeans, to recover management damages with glyphosate at postemergence application on seed vigor in post-harvest and post six months storage. The seeds originated from a field experiment conducted , which included two applications of glyphosate, concomitant with foliar fertilizer in growth stages V4 and V6, with 0.00, 113.50 and 227.00 mg ha-1doses of Mn2+. Germination, GSI (Germination Speed Index), electrical conductivity tests and the first count of seeds were conducted. The application of Mn did not affect the physiological quality of RR soy in postharvest. However, in post-storage, higher doses of Mn had a negative effect on tests of abnormal seedlings, GSI and electrical conductivity. The applications of Mn, regardless of the developmental stage, did not interfere in the germination and first count tests, with and without storage. The electrical conductivity test showed a higher correlation with the seed germination test in the post-harvest treatment.

Published: September 2015

In general, Latosols have low levels of available P, however, the influence of the parent material seems to be decisive in defining the pool and predominant form of P in these soils. This study evaluated P availability by extraction with Mehlich-1 (M-1) and Ion Exchange Resin (IER), from samples of B horizons of Ferric and Perferric Latosols developed from different parent materials. To this end, in addition to the physical and chemical characterization of soils, 10 sequential extractions were performed with M-1 and IER from samples of B horizons (depth between 0.8 and 1.0 m). Total contents of Ca, P, Fe, Al, and Ti were determined after digestion with nitric, hydrofluoric and perchloric acids. The effects of sequential P extractions on Fe oxides were also evaluated from the analyses of dithionite-citrate-bicarbonate and ammonium acid oxalate. The high similarity between contents of P accumulated after sequential extractions with M-1 and IER in soils developed on tuffite indicated a predominance of P-Ca. Higher contents of P after a single IER extraction show greater efficiency in P removal from highly weathered soils, as from the Latosols studied here. The P contents also show the high sensitivity of extractant M-1 in highly buffered soils. Furthermore, a single extraction with extractant M-1 or IER is not sufficient to estimate the amount of labile P in these soils.
NITROGEN LOSS BY EROSION FROM MECHANICALLY TILLED AND UNTILLED SOIL UNDER SUCCESSIVE SIMULATED RAINFALLS

Published: September 2015

The description of the fate of fertilizer-derived nitrogen (N) in agricultural systems is an essential tool to enhance management practices that maximize nutrient use by crops and minimize losses. Soil erosion causes loss of nutrients such as N, causing negative effects on surface and ground water quality, aside from losses in agricultural productivity by soil depletion. Studies correlating the percentage of fertilizer-derived N (FDN) with soil erosion rates and the factors involved in this process are scarce. The losses of soil and fertilizer-derived N by water erosion in soil under conventional tillage and no tillage under different rainfall intensities were quantified, identifying the intervening factors that increase loss. The experiment was carried out on plots (3.5 × 11 m) with two treatments and three replications, under simulated rainfall. The treatments consisted of soil with and soil without tillage. Three successive rainfalls were applied in intervals of 24 h, at intensities of 30 mm/h, 30 mm/h and 70 mm/h. The applied N fertilizer was isotopically labeled (15N) and incorporated into the soil in a line perpendicular to the plot length. Tillage absence resulted in higher soil losses and higher total nitrogen losses (TN) by erosion induced by the rainfalls. The FDN losses followed another pattern, since FDN contributions were highest from tilled plots, even when soil and TN losses were lowest, i.e., the smaller the amount of eroded sediment, the greater the percentage of FDN associated with these. Rain intensity did not affect the FDN loss, and losses were greatest after less intense rainfalls in both treatments.

Uma topossequência apresenta solos com características estruturais e morfológicas distintas que podem alterar a susceptibilidade à deformação estrutural em curtas distâncias espaciais. Os objetivos deste estudo foram avaliar a capacidade de suporte de carga e a suscetibilidade à compactação e mensurar o efeito que cargas acima e abaixo da pressão de preconsolidação causam na permeabilidade ao ar de solos numa topossequência da Depressão Central do Rio Grande do Sul, Brasil. Amostras indeformadas foram coletadas nos horizontes de três perfis de Argissolos (Ap, A1, AB, BA, Bt1 e Bt2; Ap, A1, A2, AB, BA, Bt1 e Bt2; e Ap, A1, BA, Bt1 e Bt2) e dois de Gleissolos (A1, A2, Bg; A, Bg e Cg), no longo de uma topossequência. Essas amostras foram submetidas ao teste de compressão uniaxial, sendo avaliada a permeabilidade ao ar antes e após compressão. Na condição de capacidade de campo, os Gleissolos apresentaram menor suscetibilidade à compactação e maior capacidade de suporte de carga que os Argissolos. O teor de argila esteve diretamente correlacionado com a capacidade de suporte de carga. Portanto, foi inversamente proporcional à suscetibilidade à compactação, exceto em condições de elevada umidade do solo quando a água lubrificou as superfícies aumentando a susceptibilidade à compactação de quaisquer solos. Até 25 kPa de carga ao solo não resultou degradação física do solo, mas quando foram aplicadas cargas de 200 kPa, mesmo na condição de capacidade de campo, houve redução significativa do volume de macroporos e porosidade total em níveis inferiores ao limite crítico (0,10 m3 m-3).

Os solos cultivados com arroz irrigado no Estado de Santa Catarina apresentam características mineralógicas e químicas distintas dos solos utilizados nos estudos de calibração do extrator Mehlich-1, para estimar a disponibilidade de fósforo do solo para as plantas. Desse modo, o objetivo deste trabalho foi avaliar a eficiência dos extratores Mehlich-1, Mehlich-3, Resina em lâminas, Olsen e EDTA na predição da disponibilidade P para plantas de arroz cultivadas em sistema de alagamento em solos representativos de lavouras orizícolas do Estado de Santa Catarina. O experimento foi conduzido em casa de vegetação, com cinco solos oriundos de várias lavouras orizícolas, em 2014. Foram adicionados aos solos quatro concentrações de P, correspondendo a 0, ¼, ½ e 1,0 vez a quantidade de P para atingir 0,2 mg L-1 de P na solução do solo (com base na capacidade de adsorção de cada solo). Foram usadas três repetições por tratamento, dispostas no delineamento completamente casualizado. Após cinco dias da adição dos níveis de P, as unidades experimentais constituídas por vasos de 8 L contendo 3,5 kg de solo seco foram amostradas para determinar o P disponível do solo por cinco métodos químicos. Na sequência, essas foram alagadas e cultivadas com seis plantas de arroz por 46 dias, quando se quantificaram a massa de matéria seca e o P absorvido pela parte aérea das plantas. A eficácia dos métodos Mehlich-1, Mehlich-3, Resina em lâminas, Olsen e EDTA foi avaliada por correlação linear entre a quantidade de P extraída dos solos e a quantidade absorvida pelas plantas. A quantidade de P absorvida pelas plantas de arroz aumentou com o acréscimo das doses de P aplicadas, variando com o tipo de solo. A maior recuperação do P adicionado aos solos foi obtida pelo extrator EDTA, seguido pelo Olsen. O P extraído pelo EDTA e Mehlich-3 evidenciou melhor correlação com quantidade de P absorvida pelo arroz. O agrupamento dos solos segundo características relacionadas à adsorção de P no solo melhora a eficiência de todos os métodos em predizer a disponibilidade de P em solos cultivados com arroz no sistema de inundação.

Resumo A integração interfuncional é apontada por diversos trabalhos como uma alternativa para o aumento da excelência operacional, melhorando o desempenho organizacional por meio da melhoria da interação e colaboração nos processos organizacionais. O objetivo deste artigo é apresentar e discutir barreiras e desafios para melhoria da integração interfuncional entre Desenvolvimento de Produto (DP) e Planejamento e Controle da Produção (PCP) em Sistemas de Produção que adotam a estratégia de resposta à demanda Engineering-to-Order (ETO). Para atingir o objetivo proposto, foram utilizados um referencial teórico sobre os temas de interesse e constatações obtidas a partir do estudo de caso de três empresas metal mecânicas de grande porte que projetam e fabricam bens de capital sob encomenda. Como principais resultados, foram observadas barreiras e desafios relacionados à interação entre as áreas funcionais durante o processo de atendimento de pedido e a necessidade de ações que busquem melhorar a interação e colaboração entre DP e PCP, levando em conta as peculiaridades do ambiente ETO.

RESUMOMuitas são as suposições quanto à baixa exigência de água da palma mas tais informações dependem de estudos de análise do desempenho da cultura a diferentes condições hídricas. Assim, objetivou-se verificar o efeito de diferentes lâminas de irrigação sobre a morfofisiologia e desempenho produtivo da palma forrageira cultivada em ambiente Semiárido. O experimento foi conduzido no segundo ano produtivo da cultura, em Serra Talhada, PE. As lâminas de água aplicadas totalizaram, ao final do ciclo, 976, 1048, 1096, 1152 e 1421 mm. Na ocasião da colheita foram feitas medidas biométricas e de biomassa das plantas e em seguida obtidos índices de resposta hídrica, morfológicos, morfofisiológicos e feita análise de produtividade. Verificou-se que as lâminas de irrigação não afetaram os índices de resposta hídrica (com exceção do peso fresco do cladódio de 1ª ordem), morfológicos e morfofisiológicos (p > 0,05), assim como o desempenho produtivo; todavia, os valores médios obtidos para a biomassa verde e seca (131,16 e 8,18 t ha-1) e do número de cladódios totais (14,13 unid.), se mostraram superiores aos relatos de cultivos em condições de sequeiro. Sugerem-se condições de disponibilidade hídrica de 1048 a 1096 mm ano-1 para a palma forrageira.

Aphasia can globally or selectively affect comprehension and production of verbal and written language. Discourse analysis can aid language assessment and diagnosis. Objective: [1] To explore narratives that produce a number of valid indicators for diagnosing aphasia in speakers of Brazilian Portuguese. [2] To analyze the macrostructural aspects of the discourse of normal individuals. [3] To analyze the macrostructural aspects of the discourse of aphasic individuals. Methods: The macrostructural aspects of three narratives produced by aphasic individuals and cognitively healthy subjects were analyzed. Results: A total of 30 volunteers were examined comprising 10 aphasic individuals (AG) and 20 healthy controls (CG). The CG included 5 males. The CG had a mean age of 38.9 years (SD=15.61) and mean schooling of 13 years (SD=2.67) whereas the AG had a mean age of 51.7 years (SD=17.3) and mean schooling of 9.1 years (SD=3.69). Participants were asked to narrate three fairy tales as a basis for analyzing the macrostructure of discourse. Comparison of the three narratives revealed no statistically significant difference in number of propositions produced by the groups. A significant negative correlation was found between age and number of propositions produced. Also, statistically significant differences were observed in the number of propositions produced by the individuals in the CG and the AG for the three tales. Conclusion: It was concluded that the three tales are applicable for discourse assessment, containing a similar number of propositions and differentiating aphasic individuals and cognitively healthy subjects based on analysis of the macrostructure of discourse.

ResumoO presente trabalho avaliou a influência do estresse pré-abate e do método de abate sobre o rigor mortis do tambaqui durante armazenamento em gelo. Foram estudadas respostas fisiológicas do tambaqui ao estresse durante o pré-abate, que foi dividido em quatro etapas: despesca, transporte, recuperação por 24 h e por 48 h. Ao final de cada etapa, os peixes foram amostrados para caracterização do estresse pré-abate por meio de análises dos parâmetros plasmáticos de glicose, lactato e amônia e, em seguida, os peixes foram abatidos por hipotermia ou por asfixia com gás carbônico para o estudo do rigor mortis. Verificou-se que o estado fisiológico de estresse dos peixes foi mais agudo logo após o transporte, implicando numa entrada em rigor mortis mais rápida: 60 minutos para tambaquis abatidos por hipotermia e 120 minutos para tambaquis abatidos por asfixia com gás carbônico. Nos viveiros, os peixes abatidos logo após a despesca apresentaram estado de estresse intermediário, sem diferença no tempo de entrada em rigor mortis em relação ao método de abate (135 minutos). Os peixes que passaram por recuperação ao estresse causado pelo transporte em condições simuladas de indústria apresentaram entrada em rigor mortis mais tardia: 225 minutos (com 24 h de recuperação) e 255 minutos (com 48 h de recuperação), igualmente sem diferença em relação aos métodos de abate testados. A resolução do rigor mortis foi mais rápida nos peixes abatidos após o transporte, que foi de 12 dias. Nos peixes abatidos logo após a despesca, a resolução ocorreu com 16 dias e, nos peixes abatidos após recuperação, com 20 dias para 24 h de recuperação ao estresse pré-abate e 24 dias para 48 h de recuperação, sem influência do método de abate na resolução do rigor mortis. Assim, é desejável que o abate do tambaqui destinado à indústria seja feito após período de recuperação ao estresse, com vistas a aumentar sua passagem em rigor mortis.

ResumoAvaliaram-se as características físico-químicas, sensoriais e microbiológicas durante o armazenamento de raízes de mandioca submetidas a diferentes métodos de congelamento. As raízes foram caracterizadas fisicamente, processadas, acondicionadas em embalagem de polietileno de baixa densidade (PEBD) de 100 µm de espessura e submetidas aos diferentes tratamentos: congelamento e armazenamento a –18 °C; congelamento e armazenamento a –80 °C; congelamento com nitrogênio líquido e armazenamento a –80 °C. O período de armazenamento foi de 31 dias. O produto submetido a todos os tratamentos apresentou níveis aceitáveis de pH, acidez titulável, sólidos solúveis, ratio, ácido ascórbico e tempo para a cocção, bem como quanto à contagem dos microrganismos avaliados. Nos tratamentos congelamento e armazenamento a –18 °C e congelamento com nitrogênio líquido e armazenamento a –80 °C as raízes de mandioca foram aceitas sensorialmente durante todo o armazenamento. Apesar dos bons resultados apresentados no armazenamento de raízes de mandioca submetidas ao congelamento com nitrogênio líquido e armazenamento a –80° C, sugerem-se estudos mais aprofundados quanto às exigências e custo para a utilização dessa tecnologia em nível de produtor. A temperatura de –18 °C é satisfatória para manter o produto com características adequadas por no mínimo 31 dias.

Published: September 2015

AbstractInternational studies have shown effects of family relations on Internet addiction in young people. This research aimed to outline a discriminant profile of young people classified as dependent and not dependent on the Internet regarding to socio-biodemographic variables to parenting practices, parent-child conflict and interparental conflict. The sample consisted of 200 students (152 girls and 48 boys), between 15 and 24 years of age, 85.5% reside in Rio Grande do Sul and 14.5% in other Brazilian states. Participants responded individually to the protocol available online. The results showed that interparental conflict, parent-child conflict and the educational practice of supervision of paternal behavior discriminate dependents on Internet. The educational practice of maternal emotional support was the only discriminating variable for non-dependents. These national findings corroborate the international context studies and reinforce the importance of including the family in promotion and prevention of mental health of young people.

Published: September 2015

AbstractInterpersonal interactions as social processes reflect and influence individuals' mental health. The aim of the study was to verify how marital interactions relate to mental health, and to investigate evidence for the validity of the Checklist for Interpersonal Transactions II (CLOIT-II). Participants were 169 couples from the southeast of the Brazilian state of Goiás, aged between 18 and 55 years ( M = 21; SD = 5.48). They responded to a General Health Questionnaire (GHQ) and the CLOIT-II. Participants with low mental health problem scores in the GHQ (asymptomatic participants) tended to occupy interpersonal positions in the range between Deference/Trust and Affective warmth/Friendliness. In the group with high scores (symptomatic participants), interactions were defined by Coldness/Hostility.Mental health problems were positively correlated with mistrust, coldness and hostility and negatively correlated with positions of Affiliation. These results, in addition to supporting the validity of the CLOIT-II, indicate that the study of interpersonal relationships is relevant for the understanding of mental health.
O Papel do Consultor no Processo de Alinhamento Estratégico
Authors: Abib Gustavo , Hoppen Norberto
Published: September 2015

O Alinhamento Estratégico (AE) entre a Tecnologia de Informação (TI) e os negócios continua sendo uma prioridade para os gestores, conforme estudos recentemente realizados em vários países. Contudo, como constataram outras pesquisas feitas sobre o tema, o AE não parece ser um processo prioritário e eficaz de planejamento e gestão no dia a dia da TI nas empresas. Também, com frequência, verifica-se a ação de consultores externos no desenvolvimento e na implementação de ferramentas de TI nas empresas, tanto para uso estratégico, como operacional. O papel do consultor no processo de AE é pouco enfatizado nas pesquisas. Considerando a importância da sua atuação na área de TI, este trabalho propõe a discussão do papel do consultor no processo de AE. Para tanto, foi analisada a implantação de um portal corporativo de natureza estratégica em uma empresa transnacional de grande porte. Neste estudo de caso longitudinal, adotaram-se observação participante e entrevistas semiestruturadas como principais estratégias para a coleta dos dados. Dentre os resultados obtidos, destacam-se o complexo papel do consultor, baseado em habilidades técnicas e sociopolíticas e, em especial, as necessidades de compartilhamento de conhecimentos. Evidenciaram-se, também, competências do consultor para tornar o seu papel mais efetivo no processo de AE.

Published: September 2015

Este artigo objetiva demonstrar a análise do discurso da sustentabilidade − objeto de estudo − a partir de materiais visuais. Os relatórios de sustentabilidade divulgados pela empresa estudada durante cinco anos (2007 a 2011) foram utilizados como fontes discursivas. Concluímos que o discurso da sustentabilidade dessa empresa, a partir das perspectivas metodológicas de análise de materiais visuais e dos níveis de análise sócio-hermenêutica do discurso, é uma construção carregada de interesses explícitos e, principalmente, implícitos. O estudo contribui para a exploração da potencialidade da incorporação desses materiais à análise de fenômenos organizacionais e para o estímulo do uso dessa abordagem como prática metodológica.
