Authors: Meneguzzi Aline , Gonçalves Mayra Juline , Camargo Samila Silva , Grimaldi Fernanda , Weber Gabriela Candido , Rufato Leo
Published: April 2017

ABSTRACT: International breeding programs launched new genetic material of apple rootstocks that in addition to precocity and great yield are resistant to major diseases and soil pests encountered in the largest apple producing regions in Brazil. Given this, there is a necessity for vegetative propagation of these materials for study and possible replacement of existing rootstocks. The objective was to adapt a micropropagation protocol for new apple rootstock ‘G. 814’. In the multiplication phase were evaluated BAP concentrations: 0; 0.5; 1; 2 and 4mg L-1 and in the rooting phase were evaluated IBA concentrations: 0; 0.25; 0.50; 1; 1.5 and 2.5mg L-1. These new results demonstrated that this new rootstock selection can be propagated with this tissue culture adapted protocol. For the successful in vitro propagation of apple rootstock ‘G. 814’ it is indicated the use of 1mg L-1 BAP at multiplication phase and 1.5mg L-1 IBA at rooting phase.

ABSTRACT: Previous studies have demonstrated the antimicrobial activity of the peptide P34. In this study, the antiviral potential of P34 and the in vitro mechanism of action were investigated against bovine alphaherpesvirus type 1 (BoHV1). P34 exhibited low toxicity, a high selectivity index (22.9) and a percentage of inhibition of up to 100% in MDBK cells. Results from antiviral assays indicated that P34 did not interact with cell receptors, but it was able to inhibit the viral penetration immediately after pre-adsorption. In addition, BoHV1 growth curve in MDBK cells in the presence of P34 revealed a significant reduction in virus titer only 8h post-infection, also suggesting an important role at late stages of the replicative cycle. Virucidal effect was observed only in cytotoxic concentrations of the peptide. These findings showed that the antimicrobial peptide P34 may be considered as a potential novel inhibitor of in vitro herpesviruses and must encourage further investigation of its antiherpetic activity in animal models as well as against a wide spectrum of viruses.

ABSTRACT Objective: describe hospitalizations for ambulatory care sensitive chronic conditions in the state of Paraná, Brazil from 2000 to 2011 Method: epidemiological ecological study was to. After descriptive analysis of the data, hospitalization indicators were developed to describe the results. Results: this study’s findings suggest that efforts to implement and expand Primary Health Care in Paraná in the last decade resulted in a decrease in the proportion of hospitalizations for ambulatory care sensitive conditions and the average number of hospitalizations for noncommunicable chronic diseases, though the ratio of hospitalizations to resident population has increased. Conclusion: attention should be specifically paid to certain causes of hospitalization, such as hypertension and diabetes mellitus, to further minimize hospitalizations for Cerebrovascular Diseases and Congestive Heart Failure, which remained high.

ABSTRACT Objective analyze the working process of a Family Health Support Center, and identify its impact on workers' quality of life. Method this is an exploratory case study with descriptive and qualitative approach. Twenty Family Health Support Center workers of a social health organization located in São Paulo participated in three focus groups between June and August 2014. The empirical material was subjected to content analysis and analyzed in light of the Psychodynamics of Work. Results this study presents the dejourian category pleasure. Despite adversities faced putting the ideals of the Family Health Support Center into practice, the participants derived pleasure and satisfaction from the work process because they identify themselves with the Family Health Support Center's mission, have their work recognized, and also because learning is enabled through teamwork, performed from an interdisciplinary perspective, and permanent health education. Conclusion a new sense of life resulting from pleasure, achievement, and identification were present among the workers, indicating that resilience and self-fulfillment consolidate professional performance. Additionally, the establishment of living spaces and ways to show appreciation can increase pleasure, satisfaction, and the quality of working life in the Family Health Support Center.
Quando jovens ativistas do hip hop encontram a política partidária
Authors: Moreno Rosangela Carrilo , Almeida Ana Maria Fonseca de
Published: April 2017

Resumo O grau em que movimentos sociais podem se desenvolver associados a partidos políticos é uma questão relevante para a democracia participativa. Este artigo examina os efeitos ambíguos da aliança estabelecida entre jovens artistas e políticos profissionais numa grande cidade do interior paulista, no início dos anos 2000. O artigo explora uma abordagem interacionista da militância, percebendo-a como atividade social dinâmica e sublinhando sua dimensão temporal. Apoiando-se em entrevistas, o artigo mostra como a relação estabelecida entre jovens e um partido político contribuiu efetivamente para a construção do movimento hip hop da cidade. Progressivamente, no entanto, o crescente engajamento com as atividades partidárias dificultou uma maior dedicação à carreira artística por parte dos jovens, fazendo aumentar sua dependência com relação aos benefícios distribuídos pelo partido e, consequentemente, gerando disputas entre eles. Ocorrendo no período em que ingressavam na vida adulta, o processo culminou com a dissolução do grupo. Ao mostrar como essas relações se desenvolveram, o artigo revela as possibilidades e limites associados à interdependência entre movimentos sociais e partidos políticos, principalmente nos casos em que tais partidos assumem o governo.
Doações de campanha implicam em retornos contratuais futuros? Uma análise dos valores recebidos por empresas antes e após as eleições
Authors: Fonseca Thiago do Nascimento
Published: April 2017

Resumo O presente trabalho pretende averiguar se as empresas que efetuam doações para partidos da coalizão do governo federal recebem maiores valores contratuais, antes e após as eleições. A partir de dados do Tribunal Superior Eleitoral (TSE) sobre doações de campanha de 2006 e de valores contratuais extraídos do Portal da Transparência do Governo Federal, foi estimado o efeito mínimo de doar para integrantes da coalizão sobre os valores contratuais. Embora os estimadores contenham viés de seleção, devido a variáveis omitidas e não observadas, a expectativa do viés é positiva devido à correlação também positiva entre tratamento e variável dependente, de um lado, e entre tratamento e variáveis omitidas, de outro. Isso significa que é possível estimar o efeito mínimo de doar para a coalizão sobre retornos contratuais. O efeito sobre retornos contratuais após as eleições é baixíssimo, mas os valores contratuais recebidos por empresas antes das eleições estão associados às doações de modo expressivo. Ademais, não é possível afirmar que doadores do partido do chefe do Executivo recebem maiores contratos em relação aos financiadores da oposição. Em suma, se existe algum pacto entre empresas e integrantes da coalizão, os acordos são estabelecidos e cumpridos antes das eleições.
Estrategias de organización del sindicato Camioneros en Argentina (1991-2011)
Authors: Pontoni Gabriela A.
Published: April 2017

Resumen En los últimos veinte años, la mayor visibilidad y protagonismo del sindicato de Camioneros en el desarrollo de las relaciones laborales de la Argentina, no sólo respondió a diversos factores del contexto socioeconómico que desde 2003 alentaron la acción sindical, sino también a su trayectoria y consolidación institucional. Analizar dicho protagonismo constituye el objetivo de este artículo, el cual buscará comprender cómo aquél actor construyó y fortaleció su capacidad de organización, entendida ésta como la habilidad para configurar una estructura interna capaz de afrontar los cambios del contexto político-económico en el que la organización se desenvuelve. El abordaje metodológico seleccionado es el estudio de caso, a partir del cual se procedió a la comparación diacrónica de dos procesos socio-históricos del sindicato, 1990-2002 y 2003-2011. Para ello se realizaron entrevistas en base a una muestra intencional multivocal que facilitó la interpretación de dichos procesos. Nuestro análisis muestra que a partir del 2003 no fueron sólo las oportunidades provistas por el contexto las que fortalecieron la capacidad de organización del sindicato de Camioneros, sino que resultó fundamental la habilidad de sus dirigentes para interpretar lo que sucedía. Así, sus acciones buscaron aprovechar las características y escenarios que presentaba cada período (y contexto) estudiado. El aporte del artículo se sitúa en el campo disciplinario de las relaciones laborales, utilizando las teorías de análisis estratégico que toman como elemento central el concepto de “opciones estratégicas". Bajo esta perspectiva teórica, el estudio de la capacidad de organización del sindicato Camioneros, permite no sólo reconstruir la dinámica de las relaciones laborales argentinas entre los años 1991-2011, sino que al mismo tiempo colabora con la profundización del análisis de la heterogeneidad sectorial que mostró el resurgimiento sindical en la Argentina durante dicho período.
Bilhetes de namoro abertos ao público: mensagens e encontros às escondidas anunciados no Jornal do Commercio (década de 1870)
Authors: Far Alessandra El
Published: April 2017

RESUMO O artigo recupera e analisa uma série de bilhetes de namoro publicados nas seções de anúncio do Jornal do Commercio ao longo de toda a década de 1870. Mesmo diante das estritas regras morais existentes, em particular no interior das famílias mais abastadas do Rio de Janeiro, o namoro gradualmente ganhou amplitude e tirou proveito das novas práticas de sociabilidade que se instauraram no cenário urbano após a chegada da Família Real portuguesa. Assim sendo, exploram-se as principais temáticas presentes nessas mensagens com o intuito de mapear algumas dinâmicas, bem como dilemas e expectativas do namoro no cotidiano da vida na corte imperial.
A dança da política: trabalhadores, associativismo recreativo e eleições no Rio de Janeiro da Primeira República
Authors: Pereira Leonardo Affonso de Miranda
Published: April 2017

RESUMO Em janeiro de 1925 realizou-se na sede da Sociedade Dançante Carnavalesca Reinado de Siva, da Cidade Nova, a fundação de um “Centro Político Independente dos Operários do Distrito Federal”. Com objetivos claramente eleitorais, ele pretendia fomentar candidaturas ligadas ao mundo dos trabalhadores para as eleições municipais que se aproximavam. Frente a uma produção historiográfica que aponta para o suposto distanciamento dos trabalhadores brasileiros da Primeira República em relação às questões políticas e eleitorais, a reunião realizada no Reinado de Siva aparece como meio de investigar o sentido político da criação e funcionamento, no período, de dezenas de pequenos clubes recreativos semelhantes, de modo a analisarmos as formas e lógicas próprias que pautavam a luta por direitos de seus componentes.

Published: April 2017

RESUMO: O periparto caracteriza-se por mudanças imunes e fisiológicas na glândula mamária das fêmeas bovinas, tornando-as mais susceptiveis às mastites. Este trabalho teve o objetivo de avaliar a fagocitose da bactéria Escherichia coli pelos fagócitos do sangue e do colostro de vacas hígidas da raça Holandesa. Amostras provenientes de 22 fêmeas, entre novilhas e vacas, foram obtidas durante a primeira ordenha pós-parto, para avaliação da fagocitose, em lamínula de vidro, após estímulo com E. coli. A proporção de fagócitos espraiados do sangue foi maior quando as células foram estimuladas com bactérias (p=0,003), no entanto a taxa de fagocitose foi baixa e semelhante à observada quando as células não foram estimuladas (p=0,299). No colostro, foram constatados maiores índices de fagocitose (p=0,001) e espraiamento (p=0,000) quando os fagócitos foram estimulados com E. coli. Comparando-se os resultados obtidos para o sangue e o colostro, verificou-se, no sangue, maior proporção de fagócitos não espraiados e que não apresentavam bactérias no seu interior, estimulados (p=0,000) ou não (p=0,002) com bactéria. Houve maior taxa de espraiamento nos fagócitos do colostro quando estimulados com E. coli (p=0,002). Não se viu diferença nos percentuais de fagocitose entre as amostras de sangue e colostro incubadas (p=0,478) ou não (p=0,071) com bactérias. Os resultados permitiram concluir que E. coli influenciou no espraiamento dos fagócitos do sangue e do colostro de fêmeas bovinas da raça Holandesa no período do pós-parto imediato e auxiliarão na compreensão dos mecanismos imunológicos ocorridos nesse período, considerado o de maior susceptibilidade das fêmeas bovinas às infecções.

Feminização da advocacia e ascensão das mulheres nas sociedades de advogados
Authors: Bertolin Patrícia Tuma Martins
Published: April 2017

RESUMO O artigo trata dos processos de internacionalização e feminização da advocacia, que no Brasil ocorreram simultaneamente à estratificação da profissão. O ingresso maciço de mulheres na advocacia não conseguiu reverter a lógica masculina com que ela foi construída, no início do século XX, estando as mulheres concentradas nos estágios iniciais da carreira. A pesquisa apresentada investigou os principais óbices e as estratégias utilizadas pelas mulheres para ascender profissionalmente em dez das 20 maiores sociedades de advogados da capital paulista
Escolhas profissionais e impactos no diferencial salarial entre homens e mulheres
Authors: Madalozzo Regina , Artes Rinaldo
Published: April 2017

Resumo Nosso objetivo é entender dois principais fatores ligados à escolha profissional: o perfil dos indivíduos que optam por diferentes ocupações e a consequente diferenciação da remuneração dessas pessoas tanto por suas características pessoais como pelas escolhas ocupacionais. Usando dados da Pesquisa Nacional por Amostra de Domicílios - Pnad - 2013 (INSTITUTO BRASILEIRO DE GEOGRAFIA E ESTATÍSTICA - IBGE , 2014), concluímos que existem diferenças significativas tanto nas características dos indivíduos que escolhem ocupações tradicionais como na forma como eles são remunerados. Embora mulheres que trabalham em profissões masculinas tenham um retorno - similar aos homens - por sua escolha, elas somente diminuem a diferença salarial com seus pares se a opção for por uma profissão imperial (direito, engenharia ou medicina).

Published: April 2017

ABSTRACT: Sedimentary rocks of the Sete Lagoas Formation, exposed in the left margin of the São Francisco river (Minas Gerais State, Brazil), were deposited on the Januária-Itacarambi basement high. They show both lateral and vertical rock stacking along continuous outcrops, allowing us to carry out detailed facies analysis and sequence stratigraphy studies. Our studies also integrate data from geological mapping, macro and microscopic petrography and high-resolution C and O isotope analysis. Eight facies and four facies associations make up a sequence composed by a transgressive tract in the base, and a high stand tract in the upper portion, separated by a maximum flooding surface. The high stand tract shows a progradation stacking from the basement high apex towards progressively deeper basement areas. This stratigraphic framework, associated with others stratigraphic and isotopic features, indicates that the now exposed Januária basement high also represents a paleo-high during the sedimentation event. Aragonite pseudomorphs and dolomites coupled with δ13C values of -5‰ characterize the basal carbonate of the transgressive tract as a cap carbonate. Records of the Cloudina fossil, recognized in the high stand tract, indicate a Late Ediacaran age for the upper portion of the studied stratigraphic sequence.
Lithologies, structure and basement-cover relationships in the schist belt of the Dom Feliciano Belt in Uruguay

Published: April 2017

ABSTRACT: This work is the result of a multiyear effort to use field geology to describe lithologies, to establish contact relationships and to create a sketch of the tectonic evolution of the Meso- to Neoproterozoic metasedimentary successions within the Schist Belt of the Dom Feliciano Belt. This low-grade metamorphic cover rests on the high-grade metamorphic basement of the La China and Las Tetas complexes. This basement is Archean-Paleoproterozoic in age. The Schist Belt is overlapped unconformably by the Barriga Negra formation. The Lavalleja complex and the Barriga Negra formation both deformed together during the D2 deformation event (~ 570 -540 Ma), but the Barriga Negra only partially recorded the D2 transpressive event, whereas the Lavalleja complex was affected by both the D1 tangential event and the D2 event. Event D1 would have developed a fold nappe with vergence to the south. This hypothesis is supported by different structures: (i) recumbent and upright folds oriented E-W, (ii) subhorizontal mylonitic foliation in marbles (calc-schists), (iii) stretching lineations plunging towards the SW in metaconglomerates of the Las Tetas Complex, and (iv) a reworking of the subhorizontal foliation parallel to the Sarandí del Yí strike-slip shear zone.
Geochemistry and petrology of the Búzios Island alkaline massif, SE, Brazil
Authors: Gomes Celso de Barros , Alves Francisco Rubens , Azzone Rogério Guitarrari , Rojas Gaston Eduardo Enrich , Ruberti Excelso
Published: April 2017

ABSTRACT: The Late Cretaceous Búzios Island alkaline massif intrudes Precambrian charnockites and consists dominantly of syenitic rocks that are cut by a large number of dikes, mostly NE-trending, and representing two distinct suites, a felsic one and a mafic-ultramafic one. Alkali feldspar is the most abundant mineral; other constituents are clinopyroxene, commonly replaced by amphibole/biotite, and opaques. Accessory minerals include occasionally rare phases bearing Zr, Ti, Nb and Rare Earth Elements (REE). The felsic dikes may also have nepheline (sodalite). The mafic-ultramafic suite, in particular the lamprophyres, shows a primary mineral assemblage with olivine, clinopyroxene and amphibole in addition to a groundmass having glassy material and carbonates (ocelli). The Búzios rocks are chemically evolved, mostly of potassic affinity and mainly belong to the miaskitic series. Variation diagrams for major and trace elements show a bimodal distribution, suggesting an origin from different magmatic pulses. The rocks are interpreted as having been derived by fractional crystallization processes from a basanitic parental magma. The SiO2-undersaturated and SiO2-oversaturated associations present in the massif are apparently not linked to a single magmatic source, and in the petrogeny residual system two trends are evident: the first one towards the phonolitic minimum and the second one towards the rhyolitic minimum, possibly pointing to amphibole fractionation.

Published: April 2017

ABSTRACT: The Geological and Geodiversity Mapping binational program along the Brazil-Guyana border zone allowed reviewing and integrating the stratigraphy and nomenclature of the Roraima Supergroup along the Pakaraima Sedimentary Block present in northeastern Brazil and western Guyana. The area mapped corresponds to a buffer zone of approximately 25 km in width on both sides of the border, of a region extending along the Maú-Ireng River between Mount Roraima (the triple-border region) and Mutum Village in Brazil and Monkey Mountain in Guyana. The south border of the Roraima basin is overlain exclusively by effusive and volcaniclastic rocks of the Surumu Group of Brazil and its correlated equivalent the Burro-Burro Group of Guyana.
Geophysical perspective on the structural interference zone along the Neoproterozoic Brasília and Ribeira fold belts in West Gondwana
Authors: Motta João Gabriel , Morales Norberto , Malagutti Filho Walter
Published: April 2017

ABSTRACT: The Brasília and Ribeira fold belts have been established in south-southwestern São Francisco Craton during the Brasiliano-Pan African orogeny (0.9-0.5 Ga - Tonian to Cambrian), and played an important role in West Gondwana continent assembly. The region is given by a complex regional fold and thrust belt superposed by shearing during the orogeny late times, with superposing stress fields forming a structural interference zone. These thrust sheets encompasses assemblies from lower- to upper-crust from different major tectonic blocks (Paranapanema, São Francisco), and newly created metamorphic rocks. Re-evaluation of ground gravity datasets in a geologically constrained approach including seismology (CRUST1 model) and magnetic data (EMAG2 model) unveiled details on the deep- crust settings, and the overall geometry of the structural interference zone. The Simple Bouguer Anomaly map shows heterogeneous density distribution in the area, highlighting the presence of high-density, high metamorphic grade rocks along the Alterosa suture zone in the Socorro-Guaxupé Nappe, lying amid a series of metasedimentary thrust scales in a regional nappe system with important verticalization along regional shear zones. Forward gravity modeling favors interpretations of structural interference up North into Guaxupé Nappe. Comparison to geotectonic models shows similarities with modern accretionary belts, renewing the discussion.
MASSIFICAR SEM DEMOCRATIZAR: O EXCESSO QUE OPRIME
Authors: Pina Kleber Vieira
Published: April 2017

RESUMO: Este artigo pretende explorar um processo de exclusão que tem surgido graças ao modelo de expansão da educação superior adotado pelo Estado brasileiro. Análises realizadas acerca do crescimento histórico do número de matrículas e composição do sistema, bem como do tema da exclusão social e opressão, sugerem que as políticas nacionais pautadas pelo estímulo à iniciativa privada têm mantido, e não reduzido, como se divulga, a distância entre a elite nacional e as camadas inferiores da sociedade. É proposto que um modelo de oferta capaz de promover a cidadania e reduzir as desigualdades não pode se orientar pelas leis do mercado, já que estas tendem a estimular a concorrência entre indivíduos e, assim, mostram-se incapazes de promover reduções significativas de diferenças sociais.

RESUMO: Este artigo trata de aspectos sociocognitivos e institucionais relacionados ao descompasso entre formação instrucional, saberes docentes e mediações pedagógicas em Ciências Sociais expresso na prática docente de licenciandos e professores de Sociologia em escolas públicas e particulares do Distrito Federal do Brasil. Baseada em questionários, entrevistas semiestruturadas e análise documental, chegamos à seguinte tipologia de representações de práticas docentes em Ciências Sociais: institucionalizadas, desconexas e propositivas. Inferimos que tanto os desafios como as perspectivas para a Sociolgia no ensino médio do Distrito Federal passam pelo equilíbrio entre transposição de conteúdos instrucionais adaptados ao perfil sociocognitivo do alunato e formação e saberes docentes dos professores que atuam em contextos escolares diversos e adversos.

ABSTRACT Objective: There are no values defined as standard in the literature for the parameters of assessment of cervical sagittal balance in patients with idiopathic scoliosis. This study describes the sagittal cervical parameters in patients with idiopathic scoliosis. Methods: Study carried out in a tertiary public hospital in patients with adolescent idiopathic scoliosis, through the evaluation of panoramic radiographs in lateral view. The Cobb method was used to evaluate cervical lordosis from C2 to C7, distance from the center of gravity (COG) of the skull to C7, measurement of T1 slope, thoracic inlet angle (TIA), neck tilt, and plumb line from C7 to S1 (SVA C7-S1). A statistical analysis was performed, to demonstrate the relationship between the alignment of the thoracic spine in the sagittal plane and the cervical sagittal balance of patients with scoliosis. Results: Thirty-four patients were female (69.4%) and 15 male (30.6%). The mean values for COG-C7 were 0.71 mm (median 0.8 mm/standard deviation [SD]= 0.51 mm). For Cobb C2-C7, the mean was -11.7° (median -10°/SD= 20.4°). The mean slope of T1 was 23.5° (median 25°/SD= 9.5°). The mean cervical version was 58.8° (median 60°/DP= 15.4°). The mean TIA was 81.8° (median 85°/SD= 16.7°). The mean plumb line C7-S1 was -0.28 (-0.3/SD= 1.0). Conclusion: The analysis of the results showed that the mean values for the cervical lordosis are lower than the values described as normal in the literature, suggesting a loss of sagittal cervical balance in these patients.

ABSTRACT Objective: To present normality parameters for the cervical spine in a sample of the Brazilian population and its distribution by sex and age. Methods: This was a prospective study considering 94 asymptomatic individuals evaluated by panoramic radiograph of the spine for the analysis of the following parameters: cervical lordosis (CL), C2 sagittal vertical axis (SVA-C2), cervical sagittal vertical axis (cSVA), and T1 Slope (TA-T1). The parameter values were compared according to sex and age of individuals. Results: The mean CL was -16.5° (SD: ± 10.8°), SVA-C2 was -3.9 mm (SD: ± 29.2 mm), cSVA was 16.9 mm (SD: ± 10.6 mm) and TA-T1 was 24.8° (SD: ± 7.0°). There was no significant difference between the radiographic parameters when considered with respect to sex and age of individuals (P>0.05). The analysis of correlation among the radiographic parameters showed that the TA-T1 presented the highest correlation with the other parameters, including CL (r= 0.367, P<0.01), SVA-C2 (r= 0.434, P<0.001) and cSVA (r= 0.441, P<0.001). There was also a correlation between SVA-C2 and cSVA (r= 0.32, P= 0.001) and inverse correlation between CL and the cSVA (r= -0.242, P= 0.019). Conclusio: We introduced normality data of the cervical spine alignment in a Brazilian population sample. There was significant correlation among the analyzed parameters, especially considering TA-T1 in relation to the other parameters.

Method: This is a non-randomized prospective study with a sample of patients with failed back surgery pain syndrome diagnosed with persistent or recurrent pain after surgery to the lumbar spine (laminectomy and arthrodesis) referred to liaison in the Pain Clinic (n= 26). The instruments used were Brief Pain Inventory, Roland-Morris Questionnaire and Beck Anxiety and Depression Inventories. The generic WHOQOL-bref13 questionnaire was used to evaluate the quality of life and the fear of moving was assessed by the Tampa Scale for Kinesiophobia. Results: There was a predominance of females, the mean age was 42.3 ± 5.8 years, 43% were married and average schooling was 7 ± 4.5 years. The mean time of pain reported was 8 ± 6.8 months in addition to high levels of anxiety, depression and kinesiophobia. After the intervention, there was a significant improvement in the perception of quality of life and of all parameters evaluated (p<0.05), with functional gains as well as decreased pain threshold. Conclusion: The interdisciplinary intervention in patients with failed back surgery syndrome provides better functional performance, decreases the intensity of pain, anxiety and depression symptoms, and improves quality of life. The inclusion of this intervention associated with drug therapy may the patient develop an active and independent lifestyle.

The variables analyzed were sex, age, cost of hospitalization, fractured levels, levels of arthrodesis, surgical site infection, UTI or BCP, spinal cord injury, etiology, length of stay, procedure time, and visual analog scale (VAS) . Results: Thirty-two patients were evaluated in the study period, with a mean age of 38.68 years. Male-female ratio was 4:1 and the most frequent causes were fall from height (46.87%) and traffic accidents (46.87%). The thoracolumbar transition was the most affected (40.62%), with L1 vertebra involved in 23.8% of the time. Neurological deficit was present in 40.62% of patients. Hospital stay had a median of 14 days and patients with neurological deficit were hospitalized for a longer period (p<0.001), with an increase in hospital costs (p= 0.015). The average cost of hospitalization was U$2,874.80. The presence of BCP increased the cost of hospitalization, and patients with spinal cord injury had more BCP (p= 0.014) . Conclusion: Public policies with an emphasis on reducing traffic accidents and falls can help reduce the incidence of these injuries and studies focusing on hospital costs and rehabilitation need to be conducted in Brazil to determinate the burden of spinal trauma and spinal cord injury.

ABSTRACT Objective: To evaluate the effectiveness of intraoperative blood salvage (IBS) in reducing allogeneic transfusion in patients undergoing surgery for scoliosis. Methods: Retrospective case-control study with 69 patients who underwent surgical treatment for scoliosis correction from August 2008 to December 2014 in a teaching hospital. We used the IBS in 43 patients and it was not used in 26. The groups were compared according to the medical records, and the data were processed on SPSS 20.0. For the associations between the variable IBS and non-IBS and the independent variables we applied the χ 2 and the likelihood ratio tests, and the strength of which was calculated by their 95% CI. The means were compared by Student's t and Mann-Whitney tests. The confidence level was 0.05. Results: There were no significant differences between groups with the variables age, sex, preoperative weight, postoperative blood drainage and surgical time. There was a significant reduction of intraoperative allogeneic transfusion in the IBS group submitted to posterior arthrodesis compared with the control group, with no difference in the transfusion of red blood cells between the two groups postoperatively. In the 24 patients who underwent combined arthrodesis, there was no significant difference in allogeneic transfusion in the intra- and postoperative periods between the groups. Conclusion: The system proved to be effective in reducing allogeneic transfusion during surgery in patients undergoing posterior arthrodesis for scoliosis, but it was not effective in reducing allogeneic transfusion in the intra- and postoperative periods of those undergoing combined arthrodesis.

Este trabalho tem como objetivos avaliar o desempenho do GPR (Ground Penetrating RADAR) para aplicações batimétricas em ambiente controlado e do aplicativo “GPR Bathymetry”, desenvolvido para análise de radargramas batimétricos. O estudo foi realizado em uma caixa de decantação da estação de tratamento de água da qual se tem o “as-built”, obtido com estação total, que será empregado nos testes de validação. Realizaram-se três testes de comparação: comparações pontuais; entre Modelos Digitais de Elevação (MDE) gerados a partir do interpolador Topo to Raster; e entre os volumes calculados a partir dos MDE’s. Na comparação pontual a maior amplitude de discrepância entre as médias foi de 8cm. Para a amostra de discrepâncias entre os MDE’s, a amplitude foi de 9cm, média de 2cm, acurácia estimada de 4cm e o RMS de 3cm. Na comparação volumétrica obteve-se o valor de 800,6m³ com dados de referência e 806,4m³ com dados do GPR, resultando numa diferença de 1% entre os modelos. Conclui-se que para um reservatório construído em concreto armado, profundidades variando de 3 a 3,5 metros, o levantamento do relevo submerso empregando um GPR apresentou resultados promissores e um MDE com acurácia estimada de 4cm e discrepâncias de até 9cm

One of the problems encountered during surveys is obstruction of points to be monitored, an example of this can be found in industrial environments where there are usually pipes and equipment that do not allow the establishment of straight lines;. An alternative to the application of topographic survey techniques is the use of plane mirrors to diversion of straight lines where the points of interest are observed indirectly. This study presents a new approach to the problem, whose analytical solution is based on the principles of Geometrical Optics and Surveying. The relative positional accuracy achieved in the preliminary tests is submillimetric order, and the absolute positional accuracy is millimetric order.

The aim of this study was to investigate the vinylimidazole derivative as pharmacological preconditioning in experimental acute hypoxia and cerebral ischemia. All experiments were conducted with mice and rats. Acute hypoxia with hypercapnia was modeled by placing the mice in a glass with a glass lid shtanglazy 250 ml. Acute hypobaric hypoxia was performed putting animals under a glass cope, where from the Kamovsky pump pumped up the air which is equal to the altitude of 5000 meters (moderate hypoxia) and 11 000 meters (severe hypoxia). Cerebral ischemia in rats was modeled by one-stage bilateral common carotid artery occlusion. Separate pharmacological and hypoxic preconditioning and combined preconditioning by alternately use of pharmacological and hypoxic factors were investigated. It was revealed that combined preconditioning (tetra-(1-vinylimidazole) cobalt dichloride 30 mg/kg + moderate hypobaric hypoxia) enhance the resistance of the animal organism to acute hypoxia in the early period (in 1 hr) and delayed period (in 48 hr) more effective than the separate preconditioning by moderate hypoxia or with the help of tetra-(1-vinylimidazole) cobalt dichloride. The combined preconditioning increase the survival of rats in the early periods and in the delayed periods of cerebral ischemia performance, but doesn’t reduce the severity of neurological deficit in the surviving animals registered with the Stroke Index McGraw scale.
Pharmacological analysis of changes in the contentof diene conjugation, methyl esters of fatty acids of liver lipid fractions by cholinotropic agents during the overcooling of rats

Published: April 2017

The analysis of changes in the content of diene conjugation, fatty acid methyl esters (FAME) C20 of total lipids, fractions of free fatty acids (FFA) in the liver of animals exposed to overcooling for 3 hours and for 5 days after administration of cholinergic agents has been made. The obtained results indicate changing in the content of methyl esters of fatty acids and diene conjugation of FFA fractions after administration of pharmacological agents as neostigmine, pilocarpine, and atropine to animals on the background of cooling. Changes in the content of diene conjugation coincide with changes in the content of fatty acids (FA) C20 : 4 Δ-5,8,11,14 eicosatetraenoic acids (FA Arakhia) when pilocarpine or atropine was used. The presence of reciprocity was revealed. Basing the reciprocity factor, it was suggested that there was a possible effect of muscarine-sensitive structures of the plasmic membrane hepatocytes on the link between the content of FAME C20 Arakhia, phospholipase A2 activity and the change in the content of diene conjugation in fraction of liver FFA. A possible effect of cholinotropic agents on phospholipase A2 activity in the period of animal cooling was suggested.

The data of possibilities to use biologically active compounds, peptides and polysaccharides in particular, from sea urchins as potent sources of drugs are represented in the article. Their ability to act on the main chains of pathogenesis of the respiratory viral infections has been shown. So peptides and polysaccharides possess anti-inflammatory action due to inhibition of cyclooxygenase and inhibition of MAP kinase p38 phosphorylation, as well as antioxidant, immune correcting, antiviral and antibacterial effects. The progress in searching new drugs based on glycopeptides from sea urchins for treatment of respiratory tract infections and their complications are discussed.

The data of inter-individual variations in pharmacokinetics of antiblastomic drugs from the group of tyrosine proteinkinase inhibitors (imatinib, gefitinib and nilotinib) and antiblastomic immune modulator lenalidomide in healthy volunteers by meams of HPLC-MS/MS were represented in the article. The concentrations of the drugs studied were measured in the volunteer blood serum. The indeces Cmax (maximal concentration and time reaching), Tmax (time covering maximal concentration measure), AUC0-t (squire under pharmaceutical curve) were processed by trapetias method, Cmax/AUC0-t as well as Kel (elimination constant) and T1/2 (period of semielimination) according to individual signs. The significant individual variability revealed for imatinib, gefitinib and nilotinib in healthy volunteers indicates on necessity of therapeutic drug monitoring in patients treated with them to aim optimal dosing.

Using poly(lactic-co-glycolic) acid we developed a polymeric form of niclosamide (PFN) and investigated molecular mechanisms underlying its antitumor activity against human colorectal cancer cell lines (SW837, Caco-2, COLO 320 HSR). PFN was shown to be more cytotoxic against cancer cells and less cytotoxic against normal cells (human embryonic lung fibroblasts) as compared to niclosamide. Both niclosamide and its polymeric form caused mitochondrial damage (evaluated as a decrease in rhodamine 123 accumulation) and increased the levels of reactive oxygen species, particularly mitochondrial superoxide, resulting in the oxidative damage to biomolecules. Furthermore, niclosamide and PFN induced G0/G1 cell cycle arrest.

The conditions of Moscow 2010 summer heat wave were simulated in an accommodation module. Six healthy men aged from 22 to 46 years stayed in the module for 30 days. Measurements of gene expression in peripheral blood leukocytes before, during and 3 day after simulated heat wave were performed using qRT-PCR. We observed a shift in the expression level of certain genes after heat exposure for a long time, and rapid return to the initial level, when volunteers leaved the accommodation module. Eight genes were chosen to form the “heat expression signature”. EGR2, EGR3 were upregulated in all six volunteers, EGR1, SIRT1, CYP51A1, MAPK9, BAG5, MNDA were upregulated in 5 volunteers.

Background:Fissure in ano is one of the commonest benign and painful proctologic diseases causing considerable morbidity and reduction in quality of life. There are medical as well as surgical treatment options for anal fissure. The present study was conducted to find out the efficacy of closed internal sphincterotomy using von grafae knife for the management of chronic anal fissures.Methods: This was a study conducted at Department of surgery, KR hospital, Mysore, Karnataka, India from June 2016 to November 2016 for a period of six months. 70 patients with chronic anal fissure were randomly assigned into group A (35 patients) and group B (35 patients). Group A patients underwent open sphincterotomy, group B closed sphincterotomy using VON grafae knife. After matching the baseline characteristics; post op pain, wound infection, hematoma, fecal and flatus incontinence were compared. Data was analysed using SPSS-16.Results:3 out of 35 patients had wound infection in group A, none had infection in group B. 10 out of 35 (28%) developed flatus incontinence temporarily in group A, 6 out of 35 (17%) in group B. 2 out of 35 (5.7%) had fecal continence in group A, none had it in group B but incontinence was temporary. Pain (VAS>6) was more in group A (24) than group B (15). One patient had hematoma as a complication in group B.Conclusions:Closed internal sphincterotomy using von grafae knife is a better technique compared to open technique in terms of pain, wound infection, incontinence.
