Os convivas da morte no banquete das almas: presença de eguns em um conto de João Antônio

A literatura escrita tem sido um espaço privilegiado para a representação e, consequentemente, para o registro e divulgação dos valores e costumes de variados grupos e segmentos sociais. No conto analisado neste ensaio – Eguns –, o escritor paulistano João Antônio (1937-1996) traz um narrador que descreve com detalhes uma rara festa religiosa ocorrida na Bahia, destinada ao culto dos ancestrais. Contemplativo e respeitoso, limita-se a contar o que a tradição religiosa permite. O contato com a alteridade ganha foros de rito iniciático e a experiência – em sentido forte – é transferida ao leitor.

A importância político-cultural do Levante das Estátuas nas Homilias sobre as Estátuas de João Crisóstomo

A sociedade romana produziu estátuas abundantemente, como argumenta Stewart (2003:118). As suas funções eram diversas e vários os seus propósitos. Neste artigo, buscaremos apresentar a importância político-cultural das estátuas imperiais na sociedade romana do século IV d.C. a partir da compreensão da gravidade dos acontecimentos ocorridos durante a deflagração de um levante que ficou conhecido, na historiografia, como Levante das Estátuas. Neste levante, estátuas imperiais foram destruídas. Para tanto, utilizaremos a documentação legada por um presbítero, João Crisóstomo, que pronunciou, tradicionalmente, 21 homilias que a historiografia vinculou ao Levante das Estátuas.

Contaminação de praças públicas de Campo Grande, Mato Grosso do Sul, Brasil, por ovos de Toxocara e Ancylostoma em fezes de cães

De fevereiro a outubro de 1998, avaliou-se a contaminação de praças públicas de Campo Grande, MS, Brasil, por ovos de Toxocara e Ancylostoma, em amostras de fezes de cães. Das 74 praças examinadas, 42 (56,8%) estavam contaminadas por ovos de Ancylostoma, 8 (10,8%) com ovos de Toxocara e 7 (9,5%) com ambos.

Anticorpos contra o vírus rábico em seres humanos com atividades no Hospital Veterinário da Universidade Federal de Mato Grosso. Cuiabá, MT, Brasil

Uma caracterização do perfil sorológico de 102 indivíduos com constantes atividades no Hospital Veterinário da Universidade Federal de Mato Grosso foi realizada por meio de fichas epidemiológicas e provas sorológicas para titulação de anticorpos contra o vírus da raiva, no período de novembro de 1999 a novembro de 2000. Dessas pessoas, 27 tinham sido vacinadas em esquema de pré-exposição e 75 não tinham recebido nenhum esquema de vacinação anti-rábica. Os resultados deste estudo puderam classificar os indivíduos em diferentes grupos (G1, G2, G3 e G4). As 19 (18,6%) pessoas do grupo G1, previamente vacinadas contra raiva, apresentaram titulação abaixo de 0,5 UI/mL; no grupo G2, as 8 (7,8%) pessoas, também previamente vacinadas, apresentaram títulos superiores a 0,5UI/mL; no grupo G3, as 67 (65,6%) pessoas, não vacinadas contra o vírus rábico, apresentaram titulação abaixo de 0,5UI/mL; e finalmente no grupo G4, as 8 (7,8%) pessoas, que nunca receberam esquema vacinal, apresentaram títulos acima de 0,5UI/mL. Os resultados obtidos demonstraram que existe necessidade de avaliação epidemiológica e acompanhamento sorológico. de pessoas submetidas a vacinação anti-rábica pré-exposição em hospitais veterinários.

Comparação de métodos para determinar biomassa na região amazônica

The aboveground biomass content of a region can be estimated by either direct or indirect methods. Direct methods correspond to the biomass content determination with scales and extrapolation of results to larger areas. It is a destructive and very laborious procedure. Indirect methods utilize formulas whose entrance parameters are obtained from forest inventories. Forest inventories are made with the purpose to plan exploration and land use and the inventory data are frequently not suitable for biomass estimation. Problems with both methods increase in the Amazon region, where little information is available on forest biomass. The objective of this paper is to establish, by comparing the application of the indirect and direct methods in the determination of the biomass, the more appropriate indirect formulation to represent the characteristic vegetation of a region in the amazonian forest. A 0.2 hectare area was chosen, which was part of a major forest clearing experiment conducted in Tomé Açu, a town located 250 km south of Belém, the capital of the Brazilian state of Pará. The entire biomass in the area was weighted with scales during the three weeks that followed the cut of the forest in July 1994. A detailed inventory was carried out in the area and then the indirect method was applied in the data. Seven different formulas for determining biomass were used. Comparison of the data of real mass and the mass obtained through the application of the seven formulas indicated that the more suitable for the region is given by FW = α · φβ · Hγ, where FW is total fresh weight (kg), φ is the diameter at breast height (cm), H is the total height of the tree and α, β and γ are regression coefficients (equal to 0.026, 1.529 and 1.747, respectively).

Desarrollo ontogénico de plántulas de Guazuma ulmifolia (Sterculiaceae)

Guazuma ulmifolia is as popular reforestation tree all over Latin America. It is characteristic of the initial stages of the secondary sucession and presents potential utility in the restoring of degraded areas. There is no information about fruit, seed and seedling morphology, which is of fundamental importance for identification, extraction, management and seed germination as well as for the characterization of post-seminal development and normal seedling pattern. To obtain such information, external fruit, and external and internal seed structures were studied considenng shape, size, micropile and embryo localization, and tegumentar structures. All stages of this work were conduced in the Universidade Estadual Paulista (UNESP), Campus of Jaboticabal city. The fruits were collected in a mixed plantation in Jaboticabal city, State of São Paulo, Brazil. For the biometric study eight repetitions of ten fruits and eight repetitions of 100 seeds were utilized. For seed internal traits study, 50 seeds were drenched in a distiled water, cut, and observed with a scanning electron microscope and a stereomicroscope. For post-seminal study ten repetitions of seven seeds were scarificated chemically with sulphuric acid during 50 min, and placed to germinate in a culture medium, at 30°C, and eight hours of photoperiod. We found elipsoid, woody, indehiscent, pentacarpelar fruits, with a mean lenght of 22.61 mm (diameter 24.88 mm) and 64.0 seeds per fruit. Seed shape varies, mean length is 3.07 mm (width of 2.36 mm).The seed is bitegumented, tegmic, with a continuous, axial and curved embryo. The germination is epigeal and the seedlings are fanerocotiledoneus. Drawings of all stages are included.

Tuberculosis survey of free-ranging marsh deer (Blastocerus dichotomus) in Brazil

Esophageal-pharyngeal fluids from 53 free-ranging marsh deer (Blastocerus dichotomus) captured for a research program in the state of Mato Grosso do Sul, Brazil, were assayed for tuberculosis. Total DNA was extracted, amplified by polymerase chain reaction using specific primers for Mycobacterium tuberculosis complex (M. tuberculosis, M. bovis, M. microti, and M. africanum), and observed by agarose gel electrophoresis stained with ethidium bromide. All samples were negative. This, along with necropsy and histopathology data, suggests that these animals are not shedding and probably do not have active disease.

An outbreak of chlamydiosis in captive blue-fronted Amazon parrots (Amazona aestiva) in Brazil

Fifty-eight blue-fronted Amazon parrot (Amazona aestiva) nestlings, recovered from the illegal trade, became ill at a wildlife rehabilitation center in São Paulo State, Brazil. Clinical signs observed were nonspecific, and the mortality rate was 96.5% despite initial treatment with norfloxacin. Postmortem examinations were performed on 10 birds. Liver and spleen smears showed structures suggestive of Chlamydophila psittaci in four cases. Diagnosis was confirmed by seminested polymerase chain reaction on tissue samples. Other birds from the same location showed no clinical signs of the disease, although high complement fixation titers to C. psittaci were found in 10 adult psittacines. All birds in the facility were treated with doxycycline. The two surviving nestlings did not recover after two doxycycline treatments and were euthanatized. The high mortality rate observed in this outbreak was attributed to poor conditions of husbandry and delays in the diagnosis and treatment of the disease. After diagnosis, improved control measures for chlamydiosis were instituted.

Human pythiosis, Brazil

Pythiosis, caused by Pythium insidiosum, occurs in humans and animals and is acquired from aquatic environments that harbor the emerging pathogen. Diagnosis is difficult because clinical and histopathologic features are not pathognomonic. We report the first human case of pythiosis from Brazil, diagnosed by using culture and rDNA sequencing.

Extração semi-automática de rodovias em um par de imagens aéreas digitais utilizando geometria epipolar e programação dinâmica

The purpose of this paper is to introduce a methodology for semi-automatic road extraction from aerial digital image pairs by using dynamic programming and epipolar geometry. The method uses both images from where each road feature pair is extracted. The operator identifies the corresponding road featuresand s/he selects sparse seed points along them. After all road pairs have been extracted, epipolar geometry is applied to determine the automatic point-to-point correspondence between each correspondent feature. Finally, each correspondent road pair is georeferenced by photogrammetric intersection. Experiments were made with rural aerial images. The results led to the conclusion that the methodology is robust and efficient, even in the presence of shadows of trees and buildings or other irregularities.

Incidência de malformações congênitas em crianças concebidas através de injeção intracitoplasmática de espermatozóides

Purpose: to evaluate the incidence and types of major congenital malformations (MCM) in liveborn children conceived by intracytoplasmic sperm injection (ICSI). Methods: a total of 680 liveborn children resulted from 511 couples submitted to ICSI from January, 1999 to December, 2002. Data collection of the children was performed through standardized questionnaire and clinical examination. Of the 511 couples, 366 had been contacted for a sampling of 371 gestations. Of the 680 liveborn, 520 had been evaluated, 250 of them (48.1%) through questionnaire and 270 (51.9%) through questionnaire and physical examination. Two hundred and fifty children were from singleton pregnancies and 270 from multiple pregnancies. Malformations were classified according to the 10th revision of the International Statistical Classification of Diseases and Related Health. Only MCM were analyzed in this study. The incidence of MCM was compared with that of the general population obtained by the Latin American Collaborative Study of Congenital Malformations. The statistical analysis was performed by the χ 2 test (level of significance p<0.05). Results: of the 520 children, 15 presented MCM, resulting in an incidence of 2.9%. There was no difference in relation to the control group (p>0.05), which showed 2.6% incidence of MCM. The most frequent malformations were of cardiac origin (four isolated and two associated), corresponding to 40% of the total. The other types of MCM were: renal (three), neural tube (two), skull (one), cleft lip (one), genital (one), Down syndrome (associated with cardiac malformations) (two), and musculoskeletal (one). Six MCM occurred in children from singleton pregnancies and nine in children from multiple pregnancies. Conclusion: the liveborn children conceived by ICSI presented incidence of major congenital malformations (2.9%) near to the expected for the general population (2.6%). However, to establish the risks of MCM with precision it is necessary to continue the evaluation of the children conceived by ICSI.
