The selection of specimens resistant to chemical products is a mechanism used by arthropods for survival and maintenance in the environment. It is already known how fungi penetrate the host and their pathogenic potential at different phases of their biological cycle, however, ticks immune response against these agents need more detailed studies. The present work had as objectives: to identify and quantify the cellular types involved in the cellular response of B. microplus inoculated with entomopathogenic (M. anisopliae and B. bassiana) and non-entomopathogenic fungi (Penicillium corylophilum and Fusarium oxysporum). In this study 60 engorged females of B. microplus were used, representing six treatment groups with 10 specimens each. Ticks were inoculated with aqueous suspension of conidia. There were two control groups: in the first one ticks were inoculated with Tween 80 0,1% aqueous solution (negative control), in the second one ticks were not inoculated (testimony group). Fungi suspension or Tween 80 solution were applied in the back part of the idiosoma of the tick. The hemolinfa samples were collected during the whole period of life of the specimens, beginning 24 hours after inoculation. The haemolymph samples were fixed in methanol and stained with Giemsa. In all studied periods, cells like pro-hemocytes, plasmatocytes, granulocytes, spherulocytes and oenocytoids were observed in the specimens of all groups. Prohemocytes, plasmatocytes and spherulocytes were the most numerous cells observed in the hemolinfa. Hemocytes were absent in the group inoculated with B. bassiana 72 hours after inoculation. After this period, specimens inoculated with entomopathogenic fungi were dead. The absence of cells suggests the immune-suppressor effect of the fungi on this tick species. It was not observed when ticks were treated with M. anisopliae due to accentuated mortality caused by this fungus species. The nonentomopathogenic fungi did not affect the life cycle of this tick, being quickly eliminated of the organism. It was suggested based on the absence of conidia during sampling. / O controle biol?gico do carrapato Boophilus microplus com a utiliza??o de Metarhizium anisopliae e Beauveria bassiana tem sido avaliado por diversos pesquisadores. A sele??o de cepas resistentes ? um mecanismo adotado pelos artr?podes para sobreviv?ncia da esp?cie e sua manuten??o no ambiente. Apesar de estar esclarecida a forma como o fungo penetra no hospedeiro e comprovada sua patogenicidade sobre diferentes fases de seu ciclo biol?gico, a sua resposta imune frente a estes agentes agressores necessita de maiores estudos. O presente trabalho teve como objetivo: identificar e quantificar os tipos celulares envolvidos na resposta imune celular de B. microplus inoculados com fungos entomopatog?nicos n?o entomopatog?nicos. Na experimenta??o foram utilizados 60 f?meas ingurgitadas de Boophilus microplus, representando seis tratamentos cada um contendo 10 esp?cimes. Para os grupos inoculados com fungos entomopatog?nicos foi utilizada a suspens?o aquosa dos fungos Metarhizium anisopliae (isolado Ma 959) e Beauveria bassiana (isolado Bb 986). Nos tratamentos com fungos n?o entomopatog?nicos, Penicillium corylophilum e Fusarium oxysporum, foram formados ainda um grupo testemunha (n?o recebeu inocula??o) e um grupo inoculado com solu??o de tween 80 a 0,1% em ?gua destilada est?ril, considerado controle negativo. Nos grupos dos tratamentos com suspens?o f?ngica ou solu??o a inocula??o foi feita na regi?o posterior do idiossoma do carrapato. As coletas de hemolinfa foram realizadas durante todo o per?odo de vida dos esp?cimes, tendo inicio 24 horas ap?s inocula??o. As amostras de hemolinfa foram fixadas com metanol e coradas com Giemsa. Em todos os per?odos estudados, tanto nos esp?cimes inoculados com fungos como nos controles, foram observados pr?-hem?citos, plasmat?citos, granul?citos, esferul?citos e oenocit?ides. Pr?-hem?citos, plasmat?citos e esferul?citos foram ?s c?lulas mais numerosas na hemolinfa. Foi observada a aus?ncia de hem?citos no grupo inoculado com B. bassiana 72 horas ap?s a inocula??o, como tamb?m a morte dos esp?cimes inoculados com fungos entomopatog?nicos a partir deste per?odo. A aus?ncia de c?lulas evid?ncia o efeito imunossupressor do fungo sobre os carrapatos estudados. Caracter?stica n?o observada para Metarhizium anisopliae, mesmo tendo provocado acentuada mortalidade dos carrapatos. Os fungos n?o entomopatog?nicos n?o afetaram de forma significativa o ciclo de vida destes carrapatos, sendo rapidamente eliminados do organismo.

The treatments were immersion or inoculation of conidial suspension in R. microplus. The hemolymph was collected 24 and 48 hours after treatment. The cell-free hemolymph was separated of hemocytes by centrifugation and hemocytes resuspended in phosphate buffer pH 7.2. The amount of total protein was determined in both fractions of hemolymph and hemocytes were quantified. The cell-free hemolymph was filtered through a 100 kDa and 10 kDa membranes, and analyzed by electrophoresis and liquid chromatography (HPLC). The proteome of cell-free hemolymph (treatment by injection) was evaluated by 2DPAGE. Changes were observed in amount total protein and the amount of hemocytes, but no difference was observed in the electrophoretic profile (1D-PAGE) of the cell-free hemolymph. In haemocytes, the entomopathogens reduced the amount of serpins, while F. oxysporum caused increased. In 2D-PAGE variations were observed in both expression and presence/absence of protein between the groups. The cell-free hemolymph antimicrobial activity was tested against Escherichia coli and Staphylococcus aureus and against the fungus used in the treatment of engorged ticks. The hemolymph collected 48 hours after the immersion treatment with B. bassiana apresented activity anti-B. bassiana with 48 hours of evaluation. This hemolymph was subjected to Superose column to HPLC and peak was collected and analyzed on the analytical column C18. The fractions were collected from the C18 and its apresented activity anti-B. bassiana, but showed no activity against Candida albicans. These fractions were analyzed by Maldi-Tof and most of them had in common an ion with m/z 1,119.5; however, other ions may be involved with this activity antimicrobial. The lipids present in cell-free hemolymph, in the hemocyte and fat body were extracted and analyzed by thin layer chromatography (TLC) or HPTLC for neutral lipids and phospholipids. The classes of neutral lipids in the cell-free hemolymph were cholesterol ester, cholesterol (CHO) and fatty acids (FA), which have varied depending on the fungus used, type of treatment and observation time. Phospholipids found were phosphatidylcholine and phosphatidylethanolamine, its were not significantly altered after the fungal infection. In hemocytes, the same classes of lipids were found and B. bassiana modified phospholipids, while M. anisopliae s.l. altered FA and CHO. The fat body showed, in addition to these classes of neutral lipids, the triglycerides, which increased significantly 48 hours after inoculation with M. anisopliae s.l. The lipase activity in fat body was measured and it was demonstrated that increased activity 48 hours after inoculation, mainly in the group inoculated with Metarhizium. Therefore, the results showed alterations related to the proteins expression in the hemocytes and the cell-free hemolymph after inoculation with fungi, immunosuppression of hemocytes and antimicrobial peptides induction after infection with B. bassiana, besides changes in the lipid profile of R. microplus after infection. However, further studies are necessary to understand these changes. / O trabalho avaliou os perfis prot?ico e lip?dico de f?meas ingurgitadas de Rhipicephalus microplus ap?s infec??o com Metarhizium anisopliae s.l., Beauveria bassiana ou Fusarium oxysporum. Os tratamentos foram imers?o ou inocula??o da suspens?o conidial em R. microplus. A hemolinfa foi coletada 24 e 48 horas ap?s os tratamentos. O plasma foi separado dos hem?citos por centrifuga??o e os hem?citos resuspensos em tamp?o fosfato pH 7,2. A concentra??o de prote?na total foi determinada em ambas as fra??es da hemolinfa e os hem?citos quantificados. O plasma da hemolinfa foi filtrado em membrana de 100 kDa e 10 kDa, sendo analisados por eletroforese e cromatografia l?quida de alta efici?ncia (CLAE). O proteoma do plasma da hemolinfa (tratamento por inocula??o) foi avaliado por gel 2D. Foram observadas varia??es na quantidade de prote?na total de ambas as fra??es da hemolinfa, na quantidade de hem?citos bem como na intensidade de prote?nas/pept?deos expressos no plasma da hemolinfa. Nos hem?citos, os entomopat?genos reduziram a quantidade de serpinas, enquanto F. oxysporum causou aumento. No gel 2D foram observadas varia??es na express?o bem como na aus?ncia/presen?a de prote?nas entre os grupos. O plasma da hemolinfa teve sua atividade antimicrobiana testada contra Escherichia coli e Staphylococcus aureus e contra o fungo utilizado no tratamento das f?meas ingurgitadas. A hemolinfa coletada 48 horas ap?s o tratamento por imers?o com B. bassiana apresentou atividade anti-B. bassiana com 48 horas de avalia??o. Esta hemolinfa foi submetida ? coluna Superose de CLAE e o pico coletado analisado na coluna anal?tica C18. As fra??es coletadas da C18 apresentaram atividade anti-B. bassiana, por?m n?o apresentaram atividade contra Candida albicans. Essas fra??es foram analisadas por Maldi-Tof e a maioria delas apresentou um ?on com raz?o m/z 1.119,5; no entanto, outros ?ons podem estar envolvidos com essa atividade antimicrobiana. Os lip?deos presentes no plasma da hemolinfa, nos hem?citos e no corpo gorduroso foram extra?dos e analisados por cromatografia em camada delgada (CCD) ou CCD de alta performance para lip?deos neutros e fosfolip?deos. As classes de lip?deos neutros encontradas no plasma da hemolinfa foram colesterol-?ster, colesterol (CHO) e ?cidos graxos (AG), que sofreram altera??es em fun??o do fungo utilizado, tipo de tratamento e tempo de observa??o. Os fosfolip?deos encontrados foram fosfatidilcolina e fosfatidiletanolamina, que n?o foram significativamente alterados ap?s a infec??o f?ngica. Nos hem?citos, as mesmas classes de lip?deos foram encontradas e B. bassiana alterou os fosfolip?deos, enquanto M. anisopliae s.l. alterou os AG e CHO. O corpo gorduroso apresentou, al?m destas classes de lip?deos neutros, o triacilglicerol, que aumentou significativamente 48 horas ap?s a inocula??o com M. anisopliae s.l. A atividade lipase no corpo gorduroso foi mensurada, sendo evidenciado um aumento 48 horas ap?s a inocula??o, principalmente no grupo inoculado com Metarhizium. Portanto, os resultados demonstraram altera??es na express?o de prote?nas no plasma da hemolinfa e nos hem?citos ap?s inocula??o com os fungos, imunossupress?o dos hem?citos, indu??o de pept?deos com atividade antimicrobiana ap?s infec??o com B. bassiana, al?m de altera??es no perfil lip?dico de R. microplus ap?s infec??o. No entanto, maiores estudos s?o necess?rios para o entendimento dessas altera??es.

Due to the high level of resistance of the stable fly to most of chemical insecticides, it is necessary to search for new alternatives for their control, and one of them would be the use of entomopathogenic fungi. However, few researches related to microbial control of this fly were carried out. The objective of this study was to assess the ability of the Lecanicillium lecanii fungus in to make unfeasible eggs, larvae and pupae of the stable fly under laboratory conditions and verify the formation of inhibition zone in agar solid due to the presence of substances in the mucus and total homogenized larvae not previously exposed and sensitized to the fungus. The S. calcitrans colony was maintained in the Laborat?rio de D?pteros Hemat?fagos, UFRRJ. The tests were performed in the Laborat?rio de Controle Microbiano de Artr?podes, UFRRJ, where the strain CG 420 of L. lecanii was used to prepare the water suspensions. In assays with eggs, larvae and pupae of S. calcitrans, fungal suspensions were used at 2x108, 2x107, 2x106, 2x105 con.mL-1 concentrations, besides the positive control. In assays with eggs, they were immersed in different fungal suspension and transferred to Petri dishes with paper filter, which were added larval rearding medium and its respective suspension. Mortality was assessed five days after exposure, where it was observed whether stage change occurred. There was no significant difference in the hatching of eggs exposed to different fungal concentrations against the control. Larvae were subjected to the same treatment of eggs, and mortality was assessed ten to fifteen days after exposure. There was no significant difference in mortality of larvae exposed to the fungus when compared with the control group, however, the fungus L. lecanii was significantly able to reduce adult emergence from larvae exposed to the highest tested concentration and there was a percentage of emergence of 25,45% and 43,64% compared to 63,64% and 90,91% of the control group. The pupae were also immersed in different fungal suspensions, and transferred to Petri dishes with paper filter, added to its respective suspension. Mortality was assessed ten days after exposure. There was no significant difference in mortality of pupae exposed to different fungi concentrations. Filter paper discs were soaked in mucus samples and total homogenized from larvae of S. calcitrans not exposed and previously sensitized to the fungus L. lecanii and placed in petri dishes sown with the same fungus. It was not observed the formation of inhibition zone around the discs. The L. lecanii fungus was unable to make unfeasible eggs, larvae or pupae of S. calcitrans in tested fungal concentrations, however, was significantly able to reduce the emergence of adults when their third larvae stage were exposed to 2x108 con.mL-1 concentration. / Stomoxys calcitrans ? um d?ptero hemat?fago cujo parasitismo ocasiona perdas econ?micas relacionadas ? redu??o da produ??o leiteira e ganho de peso, al?m de estar associado ? dissemina??o e transmiss?o de agentes patog?nicos. Devido ao elevado grau de resist?ncia da mosca dos est?bulos a uma diversidade de inseticidas qu?micos, torna-se necess?rio a busca por alternativas para o seu controle, e uma delas seria a utiliza??o de fungos entomopatog?nicos. Todavia, poucas pesquisas relacionadas ao controle microbiano desta mosca foram realizadas. O objetivo deste estudo foi verificar a capacidade do fungo Lecanicillium lecanii em inviabilizar ovos, larvas e pupas de S. calcitrans em condi??es laboratoriais e verificar a forma??o de halo de inibi??o em meio de cultivo s?lido, em decorr?ncia de subst?ncias presentes no muco e no macerado total de larvas n?o expostas e previamente sensibilizadas ao fungo. A col?nia de S. calcitrans foi mantida no Laborat?rio de D?pteros Hemat?fagos, UFRRJ. Os ensaios foram realizados no Laborat?rio de Controle Microbiano de Artr?podes, UFRRJ. Nos ensaios foram utilizadas suspens?es aquosas do isolado CG 420 de L. lecanii nas concentra??es de 2x108, 2x107, 2x106, 2x105 con.mL-1, al?m do controle positivo. Nos ensaios com ovos, estes foram imersos nas suspens?es f?ngicas, e transferidos para placas de Petri com papel filtro, meio de desenvolvimento larval e 3 mL de sua respectiva suspens?o. A mortalidade foi avaliada cinco dias ap?s a exposi??o. N?o foi observada diferen?a significativa na eclos?o dos ovos tratados frente ao controle. As larvas foram submetidas ao mesmo tratamento dos ovos, e a mortalidade foi avaliada dez e quinze dias ap?s a exposi??o. N?o foi observada diferen?a significativa na mortalidade de larvas expostas ao fungo quando comparados com o grupo controle, entretanto, o fungo L. lecanii reduziu significativamente a emerg?ncia de adultos provenientes das larvas expostas ? concentra??o m?xima testada (2x108 con.mL-1) sendo observado um percentual de emerg?ncia de 25,45% e 41,82 %, em compara??o com 63,64% e 90,91% do grupo controle. As pupas tamb?m foram imersas nas suspens?es f?ngicas, e transferidas para placas de Petri com papel filtro e sua respectiva suspens?o. A mortalidade foi avaliada dez dias ap?s a exposi??o. N?o foi observada diferen?a significativa na mortalidade das pupas expostas ?s diferentes concentra??es f?ngicas. Discos de papel filtro foram embebidos em amostras de muco e macerado total proveniente de larvas de S. calcitrans n?o expostas e previamente sensibilizadas ao fungo L. lecanii e colocados em placas de Petri semeadas com o mesmo fungo (1x108 con.mL-1). N?o foi verificada a forma??o de halo de inibi??o ao redor dos discos. O fungo L. lecanii foi incapaz de inviabilizar ovos, larvas ou pupas de S. calcitrans nas concentra??es f?ngicas testadas, no entanto, reduziu significativamente a emerg?ncia de adultos quando suas larvas de terceiro est?dio foram expostas a concentra??o 2x108 con.mL-1.

Among the many challenges that are brought to this campus for the construction of an education for all, enabling universal access to knowledge and value, while the practices and traditional knowledge of indigenous peoples, is the qualification of teachers in planning mediation of construction of the teaching-learning of indigenous students at the school even other non-indigenous students. The study presented here aimed to investigate which pedagogical concepts teachers use as a basis for organizing their pedagogical work. This is a descriptive characterized as a case study, conducted at the Federal Institute of Education, Science and Technology of the Amazon - Campus S?o Gabriel da Cachoeira, with eleven professors from the Technical Course in Agriculture, which administer the technical disciplines in-vocational education in indigenous communities, as well as on campus. We collected data from four phases of work: Step 1: We did a literature search, which was backed by the theoretical background on the authors to address issues relevant to this study; Step 2: We performed the fieldwork with the course faculty Farming Technician, through questionnaires on educational concepts in school practice as well as on their professional profile; Step 3: analyze their teaching plans, which allowed us to observe how they planned their teaching practice through methodological procedures, the resources that would be used for lessons and evaluation tools; Step 4: We used participant observation to describe the involvement of teachers in the construction of Project Political campus. The material was interpreted from the theoretical framework adopted in which content analysis was used for this purpose. In seeking to understand how teachers organized both his pedagogical work, such as the Educational Policy Project of the campus, we realize that they do not understand that there is a relationship between education and society, therefore, have no understanding of the meaning of education to society where the campus is inserted and therefore there is a pedagogical concept defined the reasons for organizing their pedagogical work. To meet the multi-ethno-cultural in that region, allowing a differentiated model of education, constant updating is a fundamental need and unambiguous, and therefore stress the importance of such training to promote the continuous development of teachers, with actions that lead to investigate, search and interact, enabling the expansion of their knowledge and resilience, both in its design in relation to education, the challenges and problems of their everyday school life. / O Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Amazonas ? Campus S?o Gabriel da Cachoeira situa-se no alto Rio Negro, Amazonas, onde convivem povos ind?genas de v?rias etnias com diferentes l?nguas, usos, costumes e tradi??es. Entre os muitos desafios que est?o postos a este campus para a constru??o de uma educa??o para todos, que possibilite acesso aos conhecimentos universais e valorize, ao mesmo tempo, as pr?ticas e saberes tradicionais das popula??es ind?genas, est? o da qualifica??o dos professores em planejar a media??o da constru??o do processo ensino-aprendizagem de alunos ind?genas, no mesmo espa?o escolar de outros alunos n?o ind?genas. O estudo aqui proposto teve por objetivo investigar quais concep??es pedag?gicas os professores utilizam como base para a organiza??o do seu trabalho pedag?gico. Trata-se de uma pesquisa descritiva caracterizada como um estudo de caso, realizada no Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Amazonas ? Campus S?o Gabriel da Cachoeira, com onze professores do Curso T?cnico em Agropecu?ria, os quais ministram disciplinas da ?rea t?cnico-profissionalizante em comunidades ind?genas, assim como no campus. Realizamos a coleta de dados a partir de quatro etapas de trabalho: Etapa 1: fizemos uma pesquisa bibliogr?fica, onde houve o respaldo do embasamento te?rico nos autores que tratam das quest?es pertinentes ao presente estudo; Etapa 2: realizamos a pesquisa de campo com os professores do curso T?cnico em Agropecu?ria, por meio de question?rios sobre as concep??es pedag?gicas em sua pr?tica escolar, bem como sobre o seu perfil profissional; Etapa 3: analisamos seus planos de ensino, os quais nos permitiram observar como planejavam sua pr?tica pedag?gica, atrav?s dos procedimentos metodol?gicos, os recursos que seriam utilizados para as aulas e os instrumentos de avalia??o; Etapa 4: utilizamos a observa??o participante para descrever a participa??o desses professores na constru??o do Projeto Pol?tico Pedag?gico do campus. O material coletado foi interpretado a partir do marco te?rico adotado onde utilizamos a an?lise de conte?do para esse fim. Ao procurarmos conhecer como os professores organizaram, tanto seu trabalho pedag?gico, como o Projeto Pol?tico Pedag?gico do campus, percebemos que os mesmos n?o entendem que h? uma rela??o entre educa??o e sociedade, em consequ?ncia, n?o possuem um entendimento do sentido da educa??o para a sociedade em que o campus est? inserido e, portanto, n?o existe uma concep??o pedag?gica definida que fundamente a organiza??o de seu trabalho pedag?gico. Para atender a diversidade etno-pluri-cultural dessa regi?o, viabilizando um modelo de educa??o diferenciada, a atualiza??o permanente ? uma necessidade fundamental e inequ?voca, portanto, enfatizamos a import?ncia dessa forma??o para promover o desenvolvimento cont?nuo dos professores, com a??es que o levem a investigar, pesquisar e interagir, possibilitando a amplia??o de seus conhecimentos e a supera??o, tanto de sua concep??o em rela??o ? educa??o, quanto dos desafios e problemas do seu cotidiano escolar.

Para tal foram elaborados dois artigos um te?rico e um emp?rico. O primeiro, Hiperatividade e D?ficit de Aten??o: um olhar psicanal?tico, ? uma revis?o da literatura sobre o assunto e visa situar esta tem?tica a partir do paradigma neurobiol?gico e do paradigma psicanal?tico. A revis?o te?rica sobre o tema aborda diferentes autores que trabalham esta problem?tica a partir de uma perspectiva psicanal?tica baseada nos aportes te?ricos de Freud a autores mais contempor?neos, que fazem uma releitura dos conceitos fundamentais da psican?lise como Jean Laplanche e S?lvia Bleichmar. Neste artigo ressalta-se a contribui??o que um olhar psicanal?tico pode proporcionar na compreens?o destas manifesta??es. Com o segundo artigo, Desaten??o e Hiperatividade: Destinos do sujeito?, busca-se destacar, atrav?s da ilustra??o de duas situa??es cl?nicas, a import?ncia que um diagn?stico metapsicol?gico tem para o entendimento destas manifesta??es comportamentais e sua compreens?o dos poss?veis sentidos que elas podem ter em cada situa??o. Este estudo demonstrou a import?ncia que uma abordagem que considera o sujeito em sua subjetividade e em sua singularidade pode oferecer para a compreens?o dos comportamentos de desaten??o e hiperatividade, e abrir as possibilidades de interven??o nestas situa??es.
