PROGRAMA DE SUPORTE À PÓS-GRADUAÇÃO DE INSTS. DE ENSINO
Esta pesquisa partiu das leituras da obra de Elisa Lispector e da seguinte indagação do pesquisador: por que Elisa, publicada, considerada pela crítica e premiada na segunda metade do século XX no Brasil, caiu no esquecimento? A proposta é resgatar os motivos de interesse do trabalho da escritora. Dentre tais motivos, destacam-se -- em construção autônoma, mas inter-relacionada -- a busca da memória de uma família judaica expatriada, que fugiu da Ucrânia para o Brasil, e o questionamento constante da identidade e das relações interpessoais no contexto da dimensão temporal. As personagens, quer evidenciem ou não traços (auto)biográficos, delineiam-se, ao longo dos contos e romances, sempre empenhadas na construção de sua subjetividade. A tarefa projetada desenvolveu-se com o apoio das entrevistas feitas pelo autor da dissertação e de sua coleção de críticas referentes aos livros de Elisa, desenhos e pinturas do seu acervo, bem como fotos da família Lispector. O enfoque da situação da escritora e de sua obra teve, como principal referência teórica, os princípios da crítica biográfica, orientando não apenas a leitura de registros da vida de Elisa em contraponto à análise de amostras escolhidas de seus escritos, como também a inserção das experiências do pesquisador para a construção da figura da escritora. O objetivo maior é evidenciar a importância do resgate da obra de Elisa Lispector para a literatura brasileira.
This research started from readings of Elisa Lispector and the question: why has her work, published, well regarded by critics and awarded prizes in the second half of the twentieth century in Brazil, fallen into neglect? The idea is to highlight the points of interest in Lispector s work. Foremost among these are the following (each a good reason in its own right, but all interconnected): the memories of an expatriate Jewish family who fled Ukraine for Brazil, and the constant questioning of identity and interpersonal relations over time. The characters—whether or not they contain (auto) biographical features—in her short stories and novels are always involved with the construction of their own subjectivity. This study relied on the interviews made by the author and on his collection of criticism related to Elisa Lispector s books, drawings and paintings belonging to her, as well as photographs of the Lispector family. The basic theoretical underpinnings of this study of a writer s life and work are the principles of biographical criticism. They provide guidelines not only for the reading of the records of a writer s life in the light of analyses of samples chosen from her writings, but also for an understanding of the researcher s own experiences in his construction of the figure of Elisa Lispector. The major goal here is to underscore the importance of rediscovering her work for Brazilian literature.

Texto completoThe Rhipicephalus (Boophilus) microplus is one of the most important arthropods in veterinary medicine due economic losses and health problems caused in cattle production, mainly in Central and South America, as well as in Australia. As an alternative to chemical control, immunization of bovines with Bm86 antigen to induce a protective immune response. A synthetic peptide, SBm 7462, derived from Bm86, has been shown great results in control of ticks. The construction and synthesis of one nucleotide sequence based on this peptide might be useful for design a DNA vaccine that has many advances than peptide vaccine. A gene, called seq1, was constructed with a three repetition of nucleotide sequence of SBm 7462. It was cloned into a pCIneo vector expression in mammals, transfected in VERO cells and injected in BALB/c mouse. Two methods were used to analysis of peptide expression in vitro: DOT ELISA and PAP. In both, the results showed that the nucleotide sequence (seq1) had not been express in VERO cells. In vivo, when mice were inoculated with the expression cassette they did not response in ELISA. They elevated antibody titles only when vaccinated with the syntetic peptide SBm 7462. And, the best titles of immunoglobulins were seen when the SBm 7462 was administered subcutaneously. After that, we insert a mutation at the begging of seq1, but, the sequenciament demonstrated that any initiation codon (ATG) had been inserted.
O Rhipicephalus (Boophilus) microplus é um dos mais importantes artrópodes em medicina veterinária devido perdas econômicas e problemas de saúde causados na produção de gado na América Central e do Sul, bem como na Austrália. Como alternativa ao controle químico, a imunização de bovinos com antígeno proteíco Bm86 induz uma resposta imune protetora. Um peptídeo sintético, SBm 7462, derivado da Bm86, tem obtido excelentes resultados no controle de carrapatos. A construção e síntese de uma sequência nucleotidíca baseada neste peptídeo podem ser útil para o desenho de uma vacina de DNA que tem muitas vantagens sob uma vacina sintética. Um gene, denominado seq1, foi construído repetindo três vezes a sequência nucleotidídica do SBm 7462. Ele foi clonado no vetor de expressão em mamíferos, pCIneo, transfectado em células VERO e injetado em camundongos BALB/c. Dois métodos foram usados para análise da expressão do peptídeo in vitro: DOT ELISA e PAP. Em ambos, os resultados demonstraram que a seqüência nucleotídica (seq1) não havia sido expressa em células VERO. In vivo, quando camundongos foram inoculados com o cassete de expressão eles não responderam ao ELISA. Eles elevaram os títulos de anticorpos, apenas, quando inoculados com o peptídeo sintético SBm 7462. Os melhores títulos de imunoglobulinas foram vistos quando o SBm 7462 foi administrado subcutâneamente. Após isso, inserimos uma mutação no início do seq 1, porém, o sequenciamento demonstrou que nenhum códon de iniciação (ATG) tinha sido inserido.

Texto completoThe neosporosis is a disease caused by intracellular protozoa Neospora caninum, which is of great importance, especially in cattle, because it may cause abortion in infected animals, causing big economic losses for the cattle industry of many countries in the world. In the present study it was reported the expression, purification, and characterization of the protein NcSRS2 of N. caninum in the methylotrophic yeast Pichia pastoris. The gene ncsrs2 was cloned in the vector of expression pPICZαB, followed by the integration in the genome of yeast. The recombining protein NcSRS2 was shown in the supernatant of the culture, where later it was concentrated and purified. An indirect immunoenzymatic assay (ELISA) was developed, using seronegative and seropositive of cattle and sheep, naturally field-infected. It showed that the recombinant protein presented the antigenic characteristics of native protein, which allowed its recognition by the blood serum of different species of animals with neosporosis. The results were compared with the indirect immunofluorescence (IFI). The diagnosis test ELISA- NcSRS2 described in the present work is a specific and sensitive method for the detection of N. caninum in cattle and sheep. The results indicate that the recombinant protein produced in this work, can be used for the development of diagnosis methods with low-cost production, and in industrial scale, because they are necessary and important for the introduction of proper controlling measurements for this parasitosis in cattle flocks.
A neosporose é uma enfermidade causada pelo protozoário intracelular Neospora caninum esta é de grande importância principalmente em bovinos, pois pode ocasionar abortos nos animais infectados, causando grandes perdas econômicas para indústria pecuária de vários países do mundo. No presente estudo, foi relatada a expressão, purificação e a caracterização da proteína NcSRS2 de N. caninum na levedura metilotrófica Pichia pastoris. O gene ncsrs2 foi clonado no vetor de expressão pPICZαB seguindo de integração no genoma da levedura. A proteína recombinante NcSRS2 foi demonstrada no sobrenadante da cultura onde posteriormente foi concentrada e purificada. Um ensaio imunoenzimático indireto (ELISA) foi desenvolvido utilizando soros negativos e positivos de bovinos e ovinos naturalmente infectados a campo por N. caninum. Este demonstrou que a proteína recombinante apresentou as características antigênicas da proteína nativa o que permitiu o seu reconhecimento por soros de diferentes espécies de animais com neosporose. Os resultados foram comparados com a imunofluorescência indireta (IFI). O teste diagnóstico ELISA-NcSRS2 descrito no presente trabalho constitui um método específico e sensível para a detecção de N. caninum em bovinos e ovinos. Os resultados indicam que a proteína recombinante produzida neste trabalho pode ser utilizada para o desenvolvimento de métodos diagnósticos com menor custo de produção e em escala industrial, pois estes são necessários e importantes para a implantação de medidas de controle adequadas para esta parasitose nos rebanhos bovinos.

Texto completoDengue is an infectious viral disease transmitted by the biting of mosquitoes of Aedes genus and it is an important public health problem worldwide. Infection with any of the four serotypes (DENV 1-4) may be asymptomatic or causes illness ranging from mild viral syndrome, dengue fever (DF) to dengue hemorrhagic fever (DHF). An increasing number of dengue infection cases in children have been noted in the last years. A dengue surveillance study might be an important tool in endemic region to evaluate the incidence of dengue infection in children. Thus, the aim of this study was to investigate the prevalence of anti-dengue IgM and IgG antibodies in children in the Primary Health Care Center, Dr. Edgard Aché, located in the west region of Ribeirão Preto-SP. Children (n=271) from 1 to 15 years old were recruited during March 2010 until May 2011. After a signed consent by the person responsible for the children to participate in this study, a blood sample was collected. The children were classified in asymptomatic (n=174) or symptomatic (n=97) when they had more than one symptom suggestive of dengue according to the World Health Organization criterions. Anti-dengue IgM and IgG were detected in serum samples by a capture ELISA standardized in our laboratory. IgG capture ELISA was positive in 9,23% (25/271) and IgM capture ELISA in 8,49% (23/271) of the children. IgG capture ELISA was positive in 10,31% (10/97) of the symptomatic children and 8,62% (15/174) in asymptomatic children; while IgM capture ELISA was positive in 15,46% (15/97) of symptomatic children and 4,6% (8/174) in asymptomatic children. This study showed the high prevalence of anti-dengue antibodies in children in the west region of Ribeirão Preto. In addition, a high prevalence of dengue-infected children without symptoms was observed. The present survey demonstrated that dengue virus infection might be a problem in children\'s from Ribeirão Preto city and serve as an alert to the health authorities.

Texto completoCAVALHEIRO, N.P. Analysis of serotypes of HCV in patients from the city of São Paulo, by means of a enzyme-immunoassay method. São Paulo, 1999. 97p. Dissertação de Mestrado - Faculdade de Medicina, Universidade de São Paulo. With the objetive of analysing the prevalence of the different types of Hepatitis C Virus (HCV) in a population of chronic carriers of HCV, through a sorologic method (MUREX HCV Serotyping Assay), 219 patients were studied who showed a positive polymerase chain reaction. This sera were submitted to immunoenzimatic tests for the detection of antibodies in relation to HCV types 1, 2,3,4,5 and 6. The samples were diluted and incubated in the presence of heterologous competing peptides, with microwells coated with serotype-specific antigens of HCV. Of the 219 patients, it was possible to detect the HCV serotype in 166, revealing a sensitivity of 75.8%. The results showed a predominance of type 1 (70.0%) in our medium, followed by type 3 (22.3%) and type 2 (4.2%). Serotypes 4 and 5 were present in 1.8% of the patients, but always associated with serotype 1. These samples, in spite of fulfilling the prerequisites of validity for testing, showed a very high optical density reading for all types of viruses tested, including positive and negative controls. The possibility of cross reactions in these cases should be considered. Confirmation by genotyping and a more detailed investigation on the origin and mode of acquisition of the HCV of these patients should be researched. Type 6 was not confirmed in any of the samples tested and probably was not present in this particular collection. The epidemiological parameters evaluated were: age, sex and means of transmission. Of the 166 patients diagnosed with the HCV, 108 (65.1%) were men and 58 (34.9%) were women. The age of the patients varied from 12 to 73 years, the average being 41.1 years. The means of transmission mentioned were blood transfusion in 52 (31.3%) cases, intravenous drug use in 18 (10.8%) cases, by tatoos in 8 (4.8%) cases, 6 (3.6%) cases were sexually transmitted, 3 (1.8%) were by accident with a needle, 2 (1.2%) through work in the health field, one (0.6%) through acupunture and one by being hemophiliac. Sixty one (36.7%) patients were not able to offer any risk factor which justified the acquisition of the HCV infection. No significant difference was verified among the different types of HCV found and the different epidemiological parameters studied. The predominance of types 1, 3 and 2 is compatible with other genotyping studies which involved Brazilian samples, particularly in the city of São Paulo. The samples which showed high or low dense optical reading for all the wells of the same samples tested even the positive or negative controls, suggested confirmation by sequecing or genotyping. The praticality obtained by the HCV serotyping test, in spite of the fact that it does not identify the sub type, can be useful in clinical pratice and helpful in the prognostication of the disease, not needing the tecnology demanded by the tests which involve molecular biology.

Texto completoArboviruses are a serious public health problem in Brazil and, from these, the most important are caused by Flavivirus. Eleven Flavivirus have been described in Brazil. Of these, Saint Louis Encephalitis Virus (SLEV) and Rocio Virus (ROCV) are major public health problems and belongs to the Japanese Encephalitis Serocomplex. West Nile Virus (WNV), introduced in the American continent in 1999, has not yet been detected in Brazil. In this study, it was evaluated the circulation of SLEV, WNV and ROCV in horses, by viral isolation attempts and a serosurvey. Viral isolation attempts were performed in 11 brain tissues of horses from Paraíba state with negative results. It was used for the serosurvey, an IgG-ELISA with recombinant peptides of domain III of SLEV, WNV and ROCV envelope protein as antigens. Sera from 753 animals from São Paulo, Mato Grosso do Sul, Minas Gerais, Rio de Janeiro and Paraíba states were tested, and 271 of them were positive for SLEV (35,98%), 254 for WNV (33,73%) and 144 for ROCV (19,12%). Therefore, this ELISA has been a suitable approach for diagnosis of ancient infections by these viruses. An intense circulation of flaviviruses infecting horses was observed in the study sites. Besides, it was found, for the first time, the presence of WNV in Brazil, infecting horses from all the studied states with the only exception of Minas Gerais. Finally, serosurvey in horses proved to be an appropriate approach for surveillance of Flavivirus infections by SLEV, WNV and ROCV.

Texto completoDue to the increasing proximity between horse and man, it is of extreme importance to understand the diseases that affect horses which by chance may affect humans. Among many diseases, babesiosis and ehrlichiosis (anaplasmosis) promote high economic losses to horses herds in consequence of costs of treatment and also death, making it difficult to import and export animals: They can or not be linked affecting an animal at the same time. This study aimed to investigate and diagnose concomitant babesiosis (Babesia equi and Theileria equi) and ehrlichiosis (for ehrlichia equipment or Anaplasma phagocytophilum) in equine herds of the state of Sao Paulo, using the techniques of Nested PCR (Nested polymerase chain reaction for the diagnosis of T. equi and A. phagocytophilum) and c-ELISA (competitive enzyme-linked immunosorbent assay for diagnosis of T. equi) or ELISA (for diagnosis of A. phagocytophilum). Also to compare results obtained in these different techniques in 250 samples of horse (whole blood and serum). Results showed 38.4%, 46% and 36% positivity, respectively, in tests for the detection of Theileria equi through hematozoan, c-ELISA and Nested PCR and 0%, 3% and 0% positivity, respectively, in tests for the detection of Anaplasma phagocytophilum through blood parasites, indirect ELISA and Nested PCR. It was not observed co-infection Babesiosis and anaplasmosis in the herd study

Texto completoCandida spp is associated to almost 80% of all nosocomial fungal infections and is considered a major cause of blood stream infections. This yeast is the fourth most common cause of blood stream infections in the United States, where this agent is responsible for 8% of all invasive infections documented in this site and the crude mortality rate is between 40 and 60%. At the present, non-albicans species are related to at least 50% of all invasive infections due to Candida spp and they present differences in terms of clinical outcome as well as susceptibility to antifungal drugs. Nevertheless, the hematogenous infections due to Candida spp diagnosis remain an important challenge for all clinicians. The objective of this study was the standardization of an enzyme-linked immunosorbent assay (ELISA) to diagnose hematogenous infections due to Candida spp. Twenty five sera of patients with candidaemia from Hospital de Clínicas de Porto Alegre, a general tertiary care hospital in Southern Brazil and thirty two sera from healthy people from Centro de Biotecnologia da Universidade Federal do Rio Grande do Sul were analyzed. As antigens for ELISA, protein extracts from Candida albicans, Candida tropicalis, Candida parapsilosis, Candida guilliermondii, Candida glabrata, Candida dubliniensis and Candida krusei were used. Our results had demonstrated cross-reactivity between species as well as some false-negatives. These false-negatives may be due to a delayed, reduced or absent antibody response, which might be improved increasing the number of samples tested. The false-positives can be improved by selecting more appropriate specific antigens, as purified molecules or recombinant antigens.

A Leishmaniose visceral canina (LVC), conhecida como calazar, é uma antropozoonose endêmica no Brasil, causada pela Leishmania L. chagasi. O teste sorológico de ELISA tem sido empregado na rotina de inquéritos epidemiológicos e no auxílio diagnóstico clínico de cães suspeitos. O método de ensaio imunoenzimático em fase sólida (ELISA) usando o antígeno total de Leishmania L. chagasi (ELISA-AgT), assim como, o ELISA - Ligante de Fucose e Manose (ELISA-FML), tem demonstrado boa sensibilidade e especificidade para detectar a doença em cães assintomáticos e oligossintomáticos. O presente trabalho teve como objetivo comparar dois antígenos pelo método de ELISA no sorodiagnóstico de cães naturalmente infectados pela LVC, positivos no exame parasitológico, e agrupados em: grupo sintomático e, grupo oligossintomáticos, tendo como grupo controle cães de área não endêmica.

Texto completoThe electronegative low-density lipoprotein (LDL) is an important antigen involved in the pathogenesis of atherosclerosis. The LDL(-) causes inflammatory and immune response, leading to production of autoantibodies anti-LDL(-) and the subsequent formation of immune complexes (IC-LDL), which also contribute to the atherosclerotic process. Thus, this study aimed to develop and validate immunoassays for quantification of plasma LDL(-), anti-LDL(-) and LDL-IC(-) as well as developing tools applicable to a biosensor for LDL(-). After the standardization of each ELISA, were evaluated the performance characteristics of methods: limits of detection (LD) and quantification (LQ), intra- and inter-assays precision, accuracy, linearity of dilution and interferences. The LD and LQ of LDL(-) ELISA were 0.423 mg/L and 0.517 mg/L of LDL(-), respectively. Plasmas showed linearity when diluted 1:1000, 1:2000, 1:4000 and 1:8000. The LD and LQ of anti-LDL(-) ELISA were 0.0028 mg/L and 0.0032 mg/L of anti-LDL(-), respectively. Plasmas showed linearity when diluted 1:100, 1:200, 1:400 and 1:800. The LD and LQ of IC-LDL(-) ELISA were 0.023 g/L and 0.034 g/L of LDL-IC(-), respectively. Plasma showed linearity when diluted 1:12.5, 1:25, 1:50 and 1:100. The three ELISAs showed good intra- and inter-assays precision and recovery within the limits required for immunoassays. To develop a biosensor for LDL(-), a recombinant protein, called GFP5-scFv was expressed in Escherichia coli BL21(DE3) strain. The obtainment of this protein was performed inserting the DNA sequence of an anti-LDL(-) single chain variable fragment (scFv) in a bacterial vector with a DNA sequence of green fluorescent protein (GFP5). Thus, the scFv-GFP5 is fluorescent and has affinity for LDL(-). Were also synthesized gold nanoparticles, which can be efficiently used for quenching the fluorescence emission of GFP5-scFv. Therefore, immunoassays validated and developed applications for the biosensor are tools that have potential to be used in evaluating the pathogenesis of atherosclerosis.

Texto completoLeukotrienes (LTs) and cytokines are inflammatory mediators produced during sepsis and may have a task in modulating the secretion of vasopressin (VP). In the acute phase of sepsis, the plasma AVP concentrations are increased and in the late stage at basal levels, despite the progressive hypotension. Our goal was to analyze the effect of intraperitoneal injection of MK-886 (leukotriene synthesis inhibitor) on the production of LTs and cytokines in the infectious site and plasma of septic animals. We used Wistar rats that received intraperitoneal injection of MK-886 (4.0mg/kg) or vehicle (DMSO 5%) 1 h before induction of experimental sepsis by cecal ligation and puncture (CLP) or sham operation (OF).The animals were decapitated at 0, 4 and 24 h after surgeries and blood was collected for determination of serum sodium, hematocrit, cytokines and LTB4. The peritoneal fluid was collected for cytokine assay. The hypothalamus was removed and incubated for the analysis of cis-LTs. Serum sodium decreased, hematocrit increased and hypothalamic cis-leukotrienes did not show significant changes after 4 hours of CLP. Sepsis caused increase in the TNF-a concentrations in the site of infection, but was not detected in plasma. The cytokines IL-1b and IL-6 increased by 4 hours both in the plasma as in the site of infection. The results of LTB4 showed a decrease in plasma concentrations 24 hours after CLP. The administration of MK-886 did not alter sodium, hematocrit, and apparently neither the cis-hypothalamic leukotrienes. At the site of infection the drug caused an increase in the concentrations of TNF-a 4 and 24 hours while IL-1b remained unchanged and IL-6 increased only 4 hours after CLP. However, in the plasma the drug markedly diminished the concentrations of IL-1b and IL-6. The analysis of LTB4 in plasma showed effects of the drug in 4 hours but not 24 hours of sepsis. The results of this study suggest that LTs differentially regulate the cytokine production in the plasma and in the site of infection, and may explain the effects of these mediators in AVP secretion during sepsis.

Texto completoPasteurella multocida is an important pathogen for pigs, causing progressive atrophic rhinitis, pneumonia, pleurisy, and septicemia. For implementation of strategies to control and prevent infections, it is necessary to know about the profile of agent spread in natural conditions and in different types of production system. Given the lack of standardized serological techniques for this purpose, this study aims to evaluate the influence of different methods and sites of sample collection in the detection of animals with P. multocida by polymerase chain reaction (PCR) and ELISA. We evaluated different pairs of primers specific for the agent and the reaction that have lower detection threshold will be used in the evaluation of the study sites. Swabs were collected from the nasal cavity, tonsil and also blood of 90 animals. Among these, 14 (15.55%) were positive for Pasteurella multocida by polymerase chain reaction (PCR), all of which were nasal swabs. There are no positive animals among the tonsil swabs. In the ELISA, 25 (27.77%) were positive, and of these, three (3.33%) were positive in both the polymerase chain reaction and the ELISA and the remaining 22 (24.44%) was positive by ELISA and negative by polymerase chain reaction. Using comparison of proportion analysis, was observed a significant differences in the methodology of diagnosis in different tests considering p-value <0.0001 and a confidence interval of 95%. Concluding, the frequency of positives was significantly higher in ELISA than by the polymerase chain reaction.
