Olhares sobre a restauração da Igreja Nossa Senhora do Carmo da Antiga Sé

O trabalho examina o processo de construção de memórias relacionadas ao bem patrimonial, a partir do estudo de caso da restauração da Igreja Nossa Senhora do Carmo da antiga Sé, realizada para as comemorações do bicentenário de chegada da Família Real ao Brasil, organizada pela Prefeitura da cidade do Rio de Janeiro em 2008. Mediante a realização de entrevistas semi-diretivas com atores sociais ligados à igreja e aos órgãos responsáveis pelas obras de restauração, além do recurso à documentação gerada para e em função das obras, foram apontadas as escolhas, conflitos e negociações em jogo no planejamento e execução do projeto. Pôde-se constatar ainda, na análise do processo de restauração, a percepção polissêmica desse bem patrimonial, na medida em que esteve sujeito à introdução de novos usos e significados ligados a práticas museais e turísticas que acompanham sua recuperação arquitetônica. Finalmente, o trabalho ressalta a necessidade de ampliar os estudos sobre patrimônio, estendendo-se a análise da produção da memória social ao âmbito da recepção, pelos diferentes grupos sociais, dos bens que pretendem representar e materializar uma memória comum.

Fisiologia do estresse calórico e a utilização de eletrólitos em frangos de corte

Várias alterações metabólicas e fisiológicas são desencadeadas em frangos de corte submetidos a altas temperaturas ambientais, o que pode acarretar em grandes perdas no desempenho e na imunocompetência destas aves. Além das técnicas de controle ambiental estarem sendo freqüentemente empregadas para a redução do impacto negativo do estresse calórico sobre o desempenho das aves, outras medidas estão constantemente sendo estudadas. Nos últimos anos, o manejo nutricional adequado também tem demonstrado ser efetivo como medida preventiva para o estresse calórico, pois o funcionamento do sistema termorregulador do frango (produção de calor, rotas evaporativas e não evaporativas de dissipação de calor) pode ser influenciado pela dieta, em especial, o estabelecimento de adequados balanços eletrolíticos, devido a sua importância fisiológica no mecanismo do estresse calórico. Assim, os mecanismos nutricionais devem ser reavaliados como uma ferramenta no controle desta disfunção metabólica das aves.

Efeito do probiótico Bacillus subtilis no crescimento, sobrevivência e fisiologia de rãs-touro (Rana catesbeiana)

The probiotics are live microorganisms, in latency state, that benefices the development of the animals. The objective of this work was to evaluate the effect of the Bacillus subtilis in different doses about the growing, survival and immunological and hematological analyses in the Bullfrog (Rana catesbeiana) froglets. The test was developed in Experimental Frog farm of Agriculture Department, Pindamonhangaba, SP. Three doses of probiotics were tested (T1 - 2.5 g/Kg, T2 - 5 g/Kg and T3 - 10 g/Kg of food). The test was carried out with three simultaneous replicates, plus control group. The products were added to froglet's diet and mixed to the meal. The animals were previously feed with this diet for a period of 14 days and accompanied for about 42 days after metamorphose. Biometrics were performed every 7 days. It was evaluated the final weight, the survival, phagocytic capacity, phagocytic index and hematological analyses as hematocrit, hemoglobin level, erythrocyte number, absolute indices hematimetrycs (MCV and MCHC), differential counting of leucocytes and total counting of leucocytes and trombocytes. The results had shown that the doses of the probiotics had produced none effect on the final weight and survival. The immunological analyses had shown that the probiotics have presented immunostimulator effect, but haven't influenced the hematological parameters of the animals.

Medicina filosófica: as relações entre medicina e filosofia na Grécia antiga e em Kant

This work deals with the relationship between medicine and philosophy, which has existed since Antiquity, and will also be discussed here from Kant s perspective. It presents the historical context formed by reciprocal influences of common notions regarding health/disease, balance/justice, and just measure, which are present in the medical discourse as much as in the philosophical one. It considers that Hippocratic medicine emerges from concerns about dietetics, thus creating the link between philosophy and medicine, which is important for our analysis on Kant s contributions to Hippocratic legacy. Taking into account these considerations, the work distinguishes between two aspects which are associated within the dietetics presented by Kant in his work The conflict of the faculties, studied here in the light of his Doctrine of virtue, particularly the duties to oneself in regard the care of one s body and the teleological conception. In this sense, the work indicates the role of Kantian thinking not only to enrich medical dietetics, by lending to it moral value, but also to enrich philosophy by highlighting its therapeutic effects

A festa da urbe e o nascimento da cidade: A Cidade Antiga como prelúdio da modernidade

This work is a result of an research that aims to understand in which way the work The Ancient City of the French historian Fustel de Coulanges built a moral model for the institutions and for the construction of the French territory in the century XIX understood like The Modern City . Our intention is to present a study on the way like the ancient city it was built, when nationalist of century XIX is taking into account his connections with the space reforms and the discussion in France. In this sense, we go besides the works of the historiography of the century XIX on this subject and of the articles and tests of the beginning of the century XX, when urbanity planner tied the narrative Scientifics of Fustel with the discussion in France of this period and his contribution, through this connection between history and space, with the national education of the individuals and the formation of the French identity. In this way, we understand which History, Nation and Space were the bases of sustenance of the theory of Coulanges about The Ancient City and of the formation of the French territory. Besides, the discussion historiography between Frenchmen and Germans on the origins of his respective nations influenced Coulanges the perspective of narrating a history of the Antiquity, taking into account the cultural approach of the past and the modern Institutions

Caracterização estrutural do fator de crescimento de fibroblasto-10 (FGF-10) e seu papel na fisiologia folicular ovariana

Background: Interest in folliculogenesis has grown extensively in recent years. Nevertheless, several aspects of follicular activity are still poorly understood. Thus, in vitro culture of ovarian follicles using new substances has been established as a very viable model, enhancing the prospects for a better understanding of follicular activity. Among the family members of the fibroblast growth factor (FGFs), FGF-10 has received recent attention for its ability to regulate the development of ovarian follicles and oocyte maturation. Given the relevance of FGF-10 in the folliculogenesis process, this review aimed to describe the structural features, expression and the main biological effects of FGF-10 on the development of ovarian follicles in mammals.Review: Along this work, it was shown aspects related to structural characterization of FGF-10 and its receptors, as well as FGF-10 expression in different cell types, emphasizing its importance to follicular development. FGF-10 is a paracrine member of the family of FGFs, and is characterized by promoting biological responses via cell surface receptors (FGFRs) of tyrosine kinase-type. of these receptors, FGFR-1, FGFR-2 and FGFR-3 may undergo alternative transcriptional arrangements, enabling the formation of two isoforms (b and c) that have varying degrees of affinity for the various FGFs. Thus, seven FGFR proteins (FGFRs 1b, 1c, 2b, 2c, 3b, 3c and 4) with different binding specificities are generated from the four FGFR genes. The FGFRs transmit intracellular signals after binding with the ligand through the phosphorylation of tyrosine, which activates various transduction patterns in the cytoplasm. The signal transduction of FGF-10 may occur through three main pathways: protein of rat sarcoma (Ras)/MAPK, PLC gamma/Ca(2+) and phosphatidylinositol-3 kinase (PI3K)/protein kinase B (Akt), which are involved in the transmission of biological signals, leading to cellular proliferation and differentiation. FGF-10 mRNA expression was detected in the ovarian stroma, oocyte and theca cells of preantral and antral follicles. on the other hand, the expression of mRNA for FGF-10 receptors was found in, granulosa cells, theca cells, cumulus cells and oocytes. Although FGFs are widely distributed in different tissues and cell types, the importance and function of FGFs in the ovary are still poorly documented. FGF-10 has been shown to be an important mediator of mesenchymal and epithelial cell interactions during follicle development, promoting follicular survival, activation and growth. Besides the action on folliculogenesis, FGF-10 was recently identified as a growth factor able to improve oocyte competence. However, in antral follicles, the presence of FGF-10 is associated with increased follicular atresia, which matches its anti-estrogenic action.Discussion: From this review, we can conclude that FGF-10 is an important regulator of female reproduction. This growth factor acts in follicle survival, oocyte maturation, expansion of cumulus cells and proliferation of granulosa/theca cellsthrough direct and/or indirect actions in the control of folliculogenesis. Furthermore, FGF-10 seemed to have different effects throughout the follicular development. However, it is necessary to perform additional studies that may provide a better understanding about the importance of FGF-10 during folicullogenesis.

Dualidades nas propostas editoriais de música antiga brasileira

A partir da primeira publicação de caráter musicológico de música brasileira do século XVIII, realizada em 1951 por Francisco Curt Lange (Archivo de Música Religiosa de la Capitania Geral das Minas Gerais), surgiram iniciativas brasileiras que manifestaram as mais variadas propostas editoriais. O estudo das edições produzidas no país nas últimas cinco décadas revela várias dualidades, dentre as quais as dez mais importantes serão abordadas neste artigo: 1) publicação ou circulação informal; 2) Gesamtausgaben ou Denkmähler; 3) edição acadêmica ou edição prática; 4) fontes de um único acervo ou de vários; 5) obra isolada ou coletânea; 6) trabalho individual ou trabalho de equipe; 7) obras inéditas ou já divulgadas; 8) financiamento privado ou de instituições governamentais; 9) apenas partitura ou partituras e partes; 10) divulgação em papel ou em meios eletrônicos. Além da identificação dessas dualidades, o objetivo deste artigo é tentar compreender o seu significado e relacioná-las às atuais perspectivas editoriais da música antiga no país.

Fisiologia, concepções médicas e o estatuto da medicina em Descartes

Notre intention est montrer comment les conceptions médicales de Descartes, disséminées dans ses oeuvres et dans sa correspondance, se sont constituées a partir de deux questions fondamentales posées par le philosophe: 1 - comment fonctionne-t-il notre organisme; 2 - quel est-t-il la nature du corps animal et, en particulier, du corps humain.

Efeito de aldicarb em populações de pulgão em artrópodes benéficos e na fisiologia do algodoeiro

In order to study the efficiency of aldicarb against aphids, beneficial arthropods, and on cotton physiology, a trial was made at Jaboticabal, SP, Brazil, in 1992/93. The experimental design was a complete randomized block with seven replications and three treatments: 1) aldicarb 750 g of a.i./ha; 2) aldicarb 1050 g of a.i./ha; and 3) control. The results showed that aldicarb was effective in the control of aphids. Aldicarb applied in the furrow significantly increased boll number per plant, yield, and precociousness. The beneficial arthropods were not affected.

Regeneração natural de espécies da Mata Atlǎntica em sub-bosque de Eucalyptus saligna Smith. em uma antiga unidade de produção forestal no Parque das Neblinas, Bertioga, SP

This study aimed at characterizing the potential for natural regeneration of native vegetation in the under-story of an earlier Eucalyptus saligna Smith production stand. The study was carried out at the Parque das Neblinas, Bertioga municipality, SP, in a 45 ha third rotation stand; which had been abandoned 15 years ago for natural regeneration to occur. The sampling was done in 24 plots of 20 × 40 m. The sampled area was of 19,200 m2, with inventory made of 100% of the eucalyptus trees. All regeneration trees with a height ≥ 1.30 m and DBH ≥ 5.0 cm were measured, as well as adult individuals with DBH ≥ 5.0 cm; surveyed in two size classes. 1,417 individuals of E. saligna were measured, with a density of 738,02 individuals/ha and a basal area of 22.69 m2/ha. Among 2,763 natural regeneration individuals, 111 species belonged to 66 genera and 34 botanical families. The species represented 43.7% of the tree richness of neighboring native forest fragments. The total estimated density and the basal area were respectively 1,052.6 individuals/ha and 6.4 m2/ha of autochthonous trees with DBH ≥ 5.0 cm (Class 1); while for regeneration there were 3,864.58 individuals/ha, and 2.76 m2/ha of individuals with a height ≥ 1.30 m and DBH < 5.0 cm (Class 2). Shannon diversity (H') was 2.83 and 3.68, respectively, for Classes 1 and 2, and the corrected species richness for a 1000-individual sample (R1000) were 75.6 and 87.29 (Fisher's a index) for the same classes. The majority of the species (34.84%) was typical from the understory of wet tropical forest and had zoochoric fruit dispersal (67.57%). The results indicate that, under these conditions, a eucalyptus forest is able to provide adequate regeneration niches for native vegetation, and may represent a sink habitat for local populations.
