Mercado imobiliário informal e dinâmica urbana: o caso do bairro de Mãe Luiza Natal/RN

This paper aims at analyzing the dynamics of informal housing in Mãe Luiza, in the context of real estate valuation of the city of Natal/RN, which, like any other urban center, has problems related to access to urban land, which increasingly more is appreciated due to their scarcity and, consequently, has led to the segregation of urban spaces. Recently, the informal housing market has received special attention by scholars who wish to discuss the production of space and ways of access to urban land and housing, especially for those disadvantaged by the housing policies of the government where these exist. When talking about the housing market, we are automatically referring to concepts or categories intrinsic to the existing mode of production in our society - the capitalism. Thus, the categories: income, value (use and exchange), commodity, capital, profits and capital gains, along with other important concepts as well as land use (urban) and real estate agents are of great relevance to discussion we intend to do within the context of production space

Propolis immunomodulatory activity on TLR-2 and TLR-4 expression by chronically stressed mice

Our group has been investigating the immunomodulatory activity of propolis in stressed mice. In this work, we wish to report the action of propolis in chronically stressed mice, assessing the Toll-like receptor (TLR2 and TLR-4) expression by spleen cells and corticosterone levels as a stress indicator. Male C57BL/6 mice were divided into four groups: G1 was considered the control; G2 was treated with propolis (200mg kg(-1)); G3 was submitted to restraint stress for 14 days; and G4 was treated with propolis and immediately submitted to stress. After sacrifice, spleens were removed and TLR-2 and TLR-4 gene expression was analysed. TLR-2 and TLR-4 expression was increased in propolis-treated mice, and propolis administration to stressed mice prevented the inhibition of TLR-2 and TLR-4 expression. No differences were seen in the corticosterone levels among the groups. Propolis exerted an immunomodulatory action in chronically stressed mice, upregulating TLR-2 and TLR-4 mRNA expression, contributing to the recognition of microorganisms and favouring the initial steps of the immune response during stress.

Purification of papain from fresh latex of Carica papaya

No presente trabalho apresenta-se um método de cristalização da papaína oriunda do látex fresco de mamão, o qual apresenta uma alta produtividade em relação aos métodos previamente descritos. A metodologia aqui descrita não envolve o uso de reagentes sulfidrílicos, a papaína foi obtida de forma praticamente pura, apresentando uma simples banda quando submetida a eletroforese, e com propriedades idênticas àquelas obtidas por outros métodos. A atividade específica foi determinada utilizando Z-gly-pNP e BAEE como substrato. A papaína obtida por essa metodologia, sem uso de substâncias tais como cisteína e ditiotreitol, apresenta-se na forma de um complexo com inibidores naturais, os quais podem ser removidos por diálise.

Edge detection and noise removal by use of a partial differential equation with automatic selection of parameters

This work deals with noise removal by the use of an edge preserving method whose parameters are automatically estimated, for any application, by simply providing information about the standard deviation noise level we wish to eliminate. The desired noiseless image u(x), in a Partial Differential Equation based model, can be viewed as the solution of an evolutionary differential equation u t(x) = F(u xx, u x, u, x, t) which means that the true solution will be reached when t ® ¥. In practical applications we should stop the time ''t'' at some moment during this evolutionary process. This work presents a sufficient condition, related to time t and to the standard deviation s of the noise we desire to remove, which gives a constant T such that u(x, T) is a good approximation of u(x). The approach here focused on edge preservation during the noise elimination process as its main characteristic. The balance between edge points and interior points is carried out by a function g which depends on the initial noisy image u(x, t0), the standard deviation of the noise we want to eliminate and a constant k. The k parameter estimation is also presented in this work therefore making, the proposed model automatic. The model's feasibility and the choice of the optimal time scale is evident through out the various experimental results.

Aprendendo línguas estrangeiras in-tandem: histórias de identidades

A Pesquisa Narrativa de Clandinin & Connelly (2000) compreende a experiência humana como histórias vividas e contadas. Nesta abordagem qualitativa de pesquisa, os participantes contam histórias e os pesquisadores as recontam e as reconstroem por meio de narrativas acerca das experiências. Tendo este arcabouço metodológico como orientador de nossos procedimentos de pesquisa, neste artigo investigamos nossa experiência compartilhada de aprendizagem in-tandem do português e do italiano - no caso, uma experiência de oito meses por meio de um tandem face-a-face. Neste período, vivenciamos e coletamos dados acerca de nosso processo de aprender a língua um do outro: anotações de campo, mensagens reflexivas de e-mail trocadas durante o período e o conteúdo anotado durante as aulas. Ao reviver nossas histórias vividas durante aquele período, por meio da narrativa aqui apresentada, ressaltamos os elementos de identidade no nosso tandem que acreditamos estarem relacionados à aprendizagem. Também individuamos os elementos desencadeadores de identidade específicos deste contexto de aprendizagem.

As ciências sociais, a comunicação e a saúde

Comunicação, o termo central do título deste trabalho, pretende realmente ser uma espécie de pivô da articulação que queremos aqui estabelecer entre as ciências sociais e a saúde. Por um lado, a sua emergência como um campo de questões diferenciadas, com objetos e olhares relativamente novos, no seio do pensamento social já desde fins do século 18, passando pelas suas primeiras elaborações teóricas e estudos empíricos, já no quadro das ciências sociais, desde meados do século 19, depois pela sua diferenciação como um campo disciplinar em separado, em meados do século 20, até se tornar um verdadeiro emblema das sociedades contemporâneas, neste limiar do século 21. Por outro lado, as relações entre o que preferimos genericamente chamar de pensamento sobre a comunicação, rastreado no percurso histórico acima, e o campo da saúde, no seu mais amplo sentido. Assim, propomo-nos, primeiramente, a reconstituir a emergência e as evoluções desse pensamento sobre a comunicação nos últimos dois ou três séculos, destacando o seu profundo enraizamento nas ciências sociais, e, secundariamente, apontar as relações privilegiadas e variáveis ao longo da história entre esse pensamento e o conhecimento e a prática em saúde.

Formulário do perfil psicossocial do paciente anoftálmico com indicação de prótese ocular

The patient with anophthalmia may present feelings of inferiority and rejection. Knowing his/her needs and expectations contribute to a better technical intervention. Purpose: To elaborate a questionnaire of the psychosocial profile of the patient with anophthalmia with indication of ocular prosthesis. Methods: An exploratory research was used to elaborate the questionnaire, by means of a guided interview followed by writing down what was said by the interviewees, who were adult patients of the Bucco-Maxillo-Facial Prosthesis Center of FOSJC - UNESP. The guided interview was made up of 14 items directly related to the future outline of the profile. Each item of the interview resulted in questions of the questionnaire, which was pretested twice before reaching its final version. Results: The patients reported, in the exploratory research, unpleasant feelings with the loss of the eye; relationship shyness; expectations regarding surgery and prosthesis use; a wish to receive explanations and to hold their opinion about the treatment. The questionnaire of the psychosocial profile of the patient with anophthalmia with indication of ocular prosthesis is, therefore, made of 43 questions divided into 5 blocks in order to aid the comprehension of the inquired aspects and to facilitate both the computation of data and discussion, and also to improve the selection of questions according to the objective of the researcher or professional. Conclusions: It was concluded that the questionnaire was viable, can be used in full or by selecting blocks and provide a panorama of the patient's history related to the problem he/she faces, from the loss of the ocular globe to the confection of the prosthesis.
