Abstract: Parrots in captivity are frequently affected by Escherichia coli (E. coli) infections. The objective of this study was to collect information on the carrier state for E. coli pathotypes in asymptomatic free-ranging parrots. Cloacal swabs were collected from nestlings of Hyacinth, Lear’s macaws and Blue-fronted Amazon parrots and tested by polymerase chain reaction (PCR) for virulence factors commonly found in enteropathogenic, avian pathogenic, and uropathogenic E. coli strains. In total, 44 samples were cultured and E. coli isolates were yielded, from which DNA was extracted and processed by PCR. Genes commonly found in APEC isolates from Blue-fronted Amazon parrots and Hyacinth macaws were expressed in 14 of these 44 samples. One atypical EPEC isolate was obtained from a sample from Lear’s macaw. The most commonly found gene was the increased serum survival (iss) gene. This is the first report, that describes such pathotypes in asymptomatic free-living parrots. The findings of this study suggest the presence of a stable host/parasite relationship at the time of the sampling brings a new understanding to the role that E. coli plays in captive and wild parrots. Such information can be used to improve husbandry protocols as well as help conservation efforts of free-living populations. 1. Introduction Parrots are among the most endangered group of birds worldwide, and 15 of the 84 Brazilian species are classified as being vulnerable or critically endangered [1]. Studies on parrot populations are important to establish a database that can be assessed in the event of outbreaks, which could also be useful for subsequent epidemiological studies and conservation efforts [2]. However, health surveys of free-ranging wild animals are mostly focused on retrospective studies on mortality [3, 4]. Research on diseases affecting free-ranging parrots is still scarce and studies performed often fail to maximize the scientific information that could be gathered [2, 5–8]. Such data could be of extreme importance in guiding conservation measures ex situ and in situ. The Hyacinth macaw and Lear’s macaw are well-known flagship species that have suffered heavily owing to the destruction of habitat and illegal trade. A number of studies aimed at promoting their recovery have been performed and actions taken; however, they are still classified as endangered species and face severe threats to their long-term survival [9]. On the other hand, the Blue-fronted Amazon parrot is rated as a species of least concern regarding its conservation status [9]. It is, however, the most

Abstract: nowadays the family imposes a great challenge to those who dedicate themselves to study it. its transformations are getting more and more visible, both from the point of view of the relationships internal to the family and of the relations kept with the other social institutions. in this work, we try to examine the homo-parentally, believing that this modality of family presents the most significant changes in the conjugal and parental relations, since it denies the paradigm from which the family originates: the sexual differentiation. the will of a couple to have a son, the mourning for the biological impossibility to conceive it, the choice of a way, amongst several, to carry through this desire, the relation with a third person that makes possible the coming of the son, are some of the questions we will face here.

Abstract: Continuous cell lines have been established from several ixodid and argasid tick species, representing an excellent tool suitable for the isolation of pathogens and their subsequent propagation, which in turn allows the production of antigenic material for diagnostic tests, antibody and vaccine production, and also for studies on host-vector-pathogen relationships. This paper reviews the use of tick cells for culture initiation and maintenance of two obligate intracellular bacterial pathogens, Anaplasma marginale and Anaplasma phagocytophilum. These in vitro cultivation systems have been used in a wide range of studies, covering morphological ultrastructural analysis, genetics, proteomics and biological differences between strains, including genome transcriptional and protein expression approaches, enabling comparisons between host and vector cells. Thus, such systems open a new window for a better understanding of interactions between pathogens and tick cells. Last but not least, such systems contribute to the reduction in usage of animals for experimental research, as antigenic material can be produced in reasonably large quantities without the use of in vivo species-specific systems. Linhagens contínuas de células já foram estabelecidas a partir de várias espécies de carrapatos ixodídeos e argasídeos e representam uma ferramenta excelente para o isolamento e propaga o de patógenos, permitindo a produ o de material antigênico para testes diagnósticos, produ o de anticorpos e vacinas, e também para estudos das rela es entre hospedeiro-vetor-patógenos. Este artigo revisa o uso de células de carrapatos para estabelecimento e manuten o in vitro de dois patógenos intracelulares, Anaplasma marginale e Anaplasma phagocytophilum. Estes sistemas de cultivo in vitro, têm sido utilizados em vários estudos, tais como análises morfológicas, genéticas, prote micas e estudos diferenciais entre isolados, incluindo gen mica transcricional e express es proteicas, permitindo compara es entre células dos hospedeiros e dos vetores. Tais sistemas constituem, portanto, uma nova abordagem para melhor entendimento das rela es entre patógenos e células de carrapatos. Além disso, tais sistemas contribuem para a redu o do uso de animais de experimenta o, uma vez que permitem a produ o de grandes quantidades de material antigênico sem o uso de sistemas espécie-específicos in vivo.
Família, la os e sofrimento psíquico
Maria Consuêlo Passos
Revista Mal-estar e Subjetividade , 2011,
Abstract: La composición de los lazos en la familia ha causado muchas indagaciones, sobre todo cuando llevamos en cuenta los desdoblamientos de ese grupo en el escenario de la sociedade actual, cuyas características ense an la fragilidade, discontinuidad y la fragmentación de las relaciones. En este contexto, los lazos parentales como básis de la estructuración psíquica del ni o y de su subjetivación también sufren cambios, exigen nuevas salidas y, muchas veces, generan dificultades en formación psíquica de los hijos. Son conflictos relacionados a la precariedad en el ejercício de las funciones parentales y en las referencias simbólicas de la familia, recursos indispensables a la maduración del ni o y a la emergencia de las relaciones intersubjetivas en el grupo. Esas condiciones han producido una dinamica familiar en la cual los sintomas y sufrimientos psíquicos fucionan, con frecuencia, como mecanismos de defensa del grupo y de los sujetos. Estas inquietudes traspasan las reflexiones dessarrolladas en este trabajo, que tiene como objetivo discutir la formación de los lazos en la família, articulándolos con la emergencia de sufrimientos psíquicos contemporáneos. Estos sufrimientos se presentan, en muchas situaciones, asociados a un empobrecimiento simbólico que ocurre, sobre todo, en el interior de la familia. Cuestiones como constituición del psiquismo, parentalidades, lazos y sufrimiento psíquico son articuladas objetivando contribuir no solamente para la clínica como también para las intervenciones realizadas por los agentes de la salud pública.
The Performance Art of Marina Abramovic as a Transformational Experience  [PDF]
Lília Sim?es, Maria Consuêlo Passos
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.96081
Abstract: Based on issues raised by the autobiographical memoirs of the performing artist Marina Abramovic, this article seeks to discuss the transformative potential of her work, based on the analysis of six selected performances in which the artist uses the body as an object of her art, exploring as a means of expression of physical limits, exhaustion of the mind and relationship with the public. Our objective is to investigate how the artist appropriates the performance space to discuss through psychoanalytic theory the ritualistic and transformative dimension of her work. Using the field concepts of Antonino Ferro and transformational object of Cristopher Bollas. Finally we propose an analogy between the space of performance as the analytical field, the performance and the relationship with the public proposing a transformative aesthetic experience.
Mother and Daughter Prisoners of Guilt: A Discussion of Freudian and Kleinian Theory  [PDF]
Lília Sim?es, Maria Consuêlo Passos
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.105045
Abstract: The present article starts from questions raised about the discussion of the feeling of guilt in the mother and daughter relation, mainly from the theories of Freud on the importance of the fault of the emotional development of the individuals and Melanie Klein’s on the fundamental paper in the fault on the capacity to make repairs. Our objective is to investigate how possible flaws in the processes of elaboration of ambivalent conflicts may bring guilt, rather than becoming a conductive device to this development, to become an obstacle. Finally, still based on Freud and Klein, we will address the specificities of guilt in this relationship and how it can make it difficult to construct and separate this bond.
Letramento no ensino fundamental de nove anos no Brasil: a??es legais e pedagógicas previstas nos documentos oficiais

Abstract: social literacy is a concept that has been widely addressed in studies related to reading and writing. the need for a€?students' literacy in native languages that exceeds standard school curricula is a major issue for literacy discourses in brazil (soares, 2004, 2010a; terzi, 1995; kleiman, 1995; cerutti-rizzatti, 2009, 2012). thus, this study attempts to facilitate a discussion of the politics related to increasing the number of elementary school years to nine, and verify the implications of literacy education in this new educational scenario. the theory and methodology of this study are based on social literacy new studies (street, 1984, 2010; heath, 1983; barton; hamilton, 2000) and propose an analysis of documented data concerning the introduction of the nine-year elementary school. the data of the results reveal that the initiative to increase brazilian students' education is important, but beyond increased schooling, it does not establish a clear strategy that schools should implement at this grade level. the documents describe treating literacy as a social practice, but do not specify that literacy is a part of the broader social literacy. therefore, the schools need to identify the relationship between phonemic-graphemes and graphemes-phonemic in literacy (cerutti-rizzatti, 2009) to create an effective strategy for the social practice of writing. further, the documents reveal our students' insufficient knowledge about the culture of writing.
