In this paper we intend to understand the functioning of Freudian psychism concerning the constitution of the psychic subject in his relation with knowledge. In order to do that, we will analyze one of the most important writings by Freud: An Outline of Psycho-Analysis. This choice was made because we think that the author synthesizes his thought in that book, whose maturity makes possible for us to access a later elaboration of the functioning and the conceptions we intend to analyze: The regions of Psychic apparatus; The problem of the Psycho-Analysis approach: science and philosophy; and The psychic qualities of the subject.

The Cu-Au mine of Chapada is located in the municipality of Alto Horizonte, in the northwestern portion of Goiás state and is inserted in the geological context of the Brasilia Belt, specifically the Mara Rosa Magmatic Arc, which hosts important deposits of Au and Cu-Au. The rocks found in the study area belong mainly to the Volcano-Sedimentary Sequence of Mara Rosa and are composed of basic to acidic metavolcanic rocks, psammiticpellitic metasedimentary rocks, chemical rocks and also hydrothermal products. Late intrusions occur and are represented by pegmatitic dikes and tonalitic bodies. The ore deposit of the Chapada mine is formed predominantly by the chalcopyrite-pyritemagnetite association, where pyrite is the most abundant mineral. Through the structural mapping of the mining fronts, it was able to recognize three deformational phases (Dn, Dn +1, Dn +2). During the Dn phase, isoclinal recumbent folds were formed, in association with amphibolites facies metamorphism. Later, in phase Dn +1, there was formation of drag folds and intrafolial folds in association with retrograde metamorphism in the greenschist facies. The deformational phase Dn +2, in its turn, was responsible for late symmetrical folding of the foliation, with NS and EW axes, resulting in an interference pattern of the dome-and-basin type

This study aims, by a literature review, to evaluate the effects of the phacoemulsification surgery into the endothelial cells of the cornea, especially on dogs. The phacoemulsification is a surgical technique of cataract surgery, and presents a series of factors pre, trans and post operation that can affect the cornea endothelium. Knowing that the cornea transparency is essential to the preservation of the visual acuity, and that the endothelium cells do not demonstrate an adequate regeneration, it is important to the surgeon to be aware of these factors in order to avoid or to minimize them. Among then can be mentioned: previous diseases, surgical and chemical trauma, intra-ocular lens, uveitis etc. As consequence, a reduction on the number of endothelium cells and edema can be observed, which can lead to a loss of vision by definitive cornea opacity or to late visual recuperation

Esta pesquisa tem como objetivo de examinar as estratégias de expansão das firmas brasileiras do setor de carnes (bovina, suína e avícola) para além das fronteiras nacionais a partir da literatura sobre internacionalização de empresas. Essa literatura aponta fatores como a origem do capital, o grau de internacionalização da empresa, o setor de atuação, entre outros, como importantes condicionantes que afetam esse processo. No entanto, vários desses fatores não são diretamente aplicáveis aos casos brasileiros, caracterizado por uma internacionalização tardia e, em alguns casos, rápida. Para este estudo foram selecionadas três empresas nacionais do setor de carnes que apresentam diferentes estágios de internacionalização: JBS-Friboi, Marfrig, Brasil-Foods (Perdigão e Sadia). As informações selecionadas sobre cada empresas foram reunidas em dossiês corporativos, e analisadas através de estudos de casos, permitiram examinar e comparar as estratégias globais das empresas. Os resultados permitem concluir que as duas primeiras empresas demonstram uma estratégia agressiva de internacionalização (em certa medida a primeira fazendo o papel de líder e a segunda de seguidora e, por isso, complementares em posicionamento nos diferentes mercados regionais), enquanto a terceira se mantém nas etapas iniciais desse processo, fortemente vinculadas às exportações a partir do Brasil

Veterinary Dentistry has grown considerably in recent years. This growth, associated to increase of knowledge among pet owners regarding responsible ownership of their pets, resulted in growing concern about the oral health of the animals that already can be observed at veterinary clinics. Among the oral diseases in dogs, infraorbital fistula, so called carnassial” fistula, is a periapical osteolytic lesion of the fourth premolar (4 SPM), often associated with periodontal disease. In its early stages, is characterized clinically by a swelling in the region of the jawbone before the formation of the fistula and leakage of a liquid serosanguineous or purulent secretion. Because of these clinical features, it is often misdiagnosed as a skin condition unrelated to the teeth. It is very important to obtain intraoral radiographs to confirm the diagnosis for performing the most appropriate treatment, according to the cause of the injury

Estudos têm demonstrado a ativação de neurônios no núcleo leito da estria terminal (NLET) durante situações aversivas. Além disso, foi demonstrado o envolvimento do NLET no controle das respostas cardiovasculares e neuroendócrinas durante o estresse. Evidências têm apontado que a neurotransmissão colinérgica, através de receptores muscarínicos, é um mecanismo envolvido no controle das respostas fisiológicas durante o estresse emocional em várias estruturas límbicas. No entanto, apesar de estudos indicarem o envolvimento de mecanismos colinérgicos do NLET no controle da função cardiovascular, não existem evidências na literatura acerca da participação da neurotransmissão colinérgica no NLET nas respostas fisiológicas ao estresse. Diante disso, nosso objetivo no presente estudo foi investigar o efeito do pré-tratamento bilateral do NLET com hemicolínio (inibidor do transportador de colina), metilatropina (antagonista de receptores colinérgicos muscarínicos) ou neostigmina (inibidor da enzima acetilcolinesterase) sobre as respostas autonômicas e neuroendócrinas desencadeadas pelo estresse por restrição agudo em ratos. Para tanto, seis dias antes dos experimentos os animais tiveram cânulas guias implantadas bilateralmente no NLET para administração dos fármacos. Vinte quatro horas antes dos experimentos um cateter de polietileno foi implantado na artéria femoral para registro dos parâmetros cardiovasculares. No dia do experimento, os animais foram submetidos a uma sessão aguda de 30 minutos de estresse por restrição 10 minutos após o tratamento farmacológico do NLET. Medidas de pressão arterial média (PAM), frequência cardíaca (FC), temperatura cutânea da cauda e dos níveis plasmáticos de corticosterona foram analisados antes e durante o estresse por restrição em todos os grupos experimentais. O estresse por restrição causou elevação... (Resumo completo, clicar acesso eletrônico abaixo)

Most cancer types are treated by antineoplastic chemotherapy, which can be performed conjointly with other treatments, such as radiotherapy and surgery. Due to its action, chemotherapy provides the possibility of cure, but it also leads to a number of adverse effects, such as myelosuppression, cutaneous and gastrointestinal toxicity, etc. Patients undergoing chemotherapy must receive constant information concerning how to prevent or minimize these effects in order to achieve better quality of life and, consequently, a more successful treatment. Hence, this study aimed at investigating the need and preference for different forms of information by oncologic patients submitted to chemotherapy. It is a cross-sectional, descriptive and quantitative study conducted at the chemotherapy division of the Botucatu School of Medicine University Hospital/SP on a sample of 50 patients older than 18 years. After previous knowledge of the study and formalization of Free Consent, the individuals answered a questionnaire containing 12 questions related to the importance attributed to the information received, from which professional and when to receive it. Data were analyzed by Fisher’s exact test and showed that 62% of the patients were females, and the remaining 38% were males of whom 46% were older than 60 years, 26% were from 50 to 60 years old, 24% from 30 to 50, and only 4% were younger than 30 years old. The patients had lymphatic (23.4%) and solid (76.6%) tumors. All the respondents reported that receiving information about the disease and its treatment was extremely important. As regards information related to side effects, 98% of patients answered that receiving it was extremely important, and only 2% answered that it was little important. Correlations were made between age, gender, and tumor type with the answers obtained for the best moment, how and from whom to receive such informatio...
