Tessituras poéticas da corporeidade na formação humana do educador infantil

Cette étude a comme sujet principal la formation humaine de l instituteur. L objectif général est d analyser et décrire les conditions créées par les vécus d un atelier corps biographique pour la resignification de la corporéité de l instituteur, fixant les questions suivantes pour l investigation : Quelles sont les implications du vécu de l atelier corps biographique dans la vie des instituteurs ? La recherche a été exposée sur l approche qualitative, suivant les principes de la recherche-action reliée à la méthode des histoires de vie. Pour révéler la beauté et la complexité du processus poïétique de la formation humaine, nous nous sommes servi de la métaphore du "dessus de lit en patchwork" comme opérateur cognitif en attachant les principes de la corporéité fondés sur la Théorie de la complexité (MORIN, 2005), la Théorie autopoïétique (MATURANA ; VARELA, 2001), la Théorie du flux (CSIKSZENTMIHALYI, 1999), les approches de transdisciplinarité (LA TORRE; MORAES, 2008), et d autobiographie (JOSSO, 2004; PINEAU, 2003; PASSEGGI, 2000;), joignant la conception de l éducation comme pratique d autonomie, de liberté, d espoir et de l enchantement (FREIRE, 1996, 1992; ASSMANN, 1995). Nous avons eu comme scène du développement de la recherche, l Unidade Educacional Infantil (UEI), la garderie qui accueille les enfants des fonctionnaires de l Université Fédérale du Rio Grande do Norte. Treise élèves (enfants), des institutrices titulaires, vacataires, boursières ont participé de l'investigation. En conptant sur eux, nous avons développé un atelier corps biographique, dans lequel nous avons réalisé 10 vécus dans la période qui a couvert le deuxième semestre de 2007 jusqu au deuxième semestre de 2008, en manifestant la réflexivité autobiographique, le ludique, la créativité, la sensibilité et la réflexivité du vécu. Nous avons utilisé comme instruments pour la construction des donnés, l observation participante, les propres vécus, le port folio, la technique du jeu de sable et l'enregistrement photographique. L analyse a montré que le vécu de la formation humaine à partir des principes de la corporéité, implique dans un parcours vers soi-même dans lequel émergent les expériences qui nous ont constitués en tant qu êtres existentiels. Pour finaliser, nous avons aperçu les répercussions dans la vie professionnelle et personnelle de ces institutrices, qui comme moi pensaient avoir besoin d exposer leur luminosité intérieure pour que l on la redécouvre. Lors des vécus des tissages, les institutrices se sont montrées impliquées aux moments de jeux, de création, de réalisation, d afection et d action réflexive, dans lesquelles la teneur humaine cachée, a été révélée, en ouvrant les possibilités pour le sentiment du mouvement de naissance de l humanisation intérieure. Pour conclure, le corps joyeux de savoir et de beauté a été révélé, et dans sa rencontre avec soi-même et avec l autre, a pu être auto- recréé

Definition of a diagnostic routine in individuals with inconclusive serology for chagas disease

Despite the existence of highly sensitive tests, inconclusive serological results are frequent in chronic chagasic infection. This study aimed to define a diagnostic conduct for 30 individuals with inconclusive serology (G3) for chagasic infection assisted at the Outpatient Unit for Infectious and Parasitic Diseases of the Botucatu School of Medicine. Twenty-one individuals with negative serology (G1) and 33 with positive serology (G2) were also studied. Serological methods ELISA, HAI, IFI and immunoblotting TESA-cruzi were used for G1, G2 and G3, and parasitological methods xenodiagnosis, hemoculture and PCR-LIT were used for G2 and G3 individuals. ELISA, HAI and IFI were performed in 5 different blood samples in G2 and G3. TESA-cruzi was carried out only once in G1, G2 and G3 and, since it is the most sensitive, it was utilized as standard. In G3, positivity for ELISA reached 86% in the fifth blood sample; the ELISA+HAI+IFI combination showed a maximum of 44.8% in the second sample; and TESA-cruzi, 76% in one single sample. Xenodiagnosis positivity was 9.4%; hemoculture showed 15.2%; and PCR-LIT exhibited 22% positivity in G2. Nevertheless, in G3, positivity percentage was 3.4% for xenodiagnosis, 6.7% for PCR-LIT, and no positive result was found for hemoculture. In G3, PCR-LIT resolved one case which was still inconclusive according to serology tests. In order to define inconclusive diagnoses, the results suggest the combined use of ELISA+HAI+IFI in 2 blood samples, decreasing the occurrence of false positive/negative results. If results remain inconclusive, the performance of TESA-cruzi and PCR-LIT, if necessary, is recommended.

The reproductive hiology and cycle of Rioraja agassizi (Muller and Henle, 1841) (Chondrichthyes : Rajidae) in southeastern Brazil, SW Atlantic Ocean

Specimens of Rioraja agassizi were collected Lit Guaruja pier, São Paulo State, Brazil, from March 2005 to March 2006. A total of: 275 males were captured. Based on the analysis of the clasper length, gonad weight, clasper gland length, alar thorns and lobule diameter, the size-at-maturity was estimated to be 32 cm. There were 1049 females in the record. Size-at-maturity was calculated in 40 cm. Sexual resting females were observed. Gonadosomatic and hepatosomatic indexes varied significantly in both sexes throughout the year. However, ovulation, egg-laying and presence of sperm in the seminal vesicle were observed all year round. For this reason, an annual cycle with at least one peak in the sexual activity is proposed for this species.

Tests to determine LC50 and discriminating doses for macrocyclic lactones against the cattle tick, Boophilus microplus

Laboratory tests were carried out on larvae and adults of the cattle tick Boophilus microplus to determine the toxicity of macrocyclic lactone acaricides (MLs). Technical and commercial MLs were used in larval packet test (LPT), larval immersion test (LIT) and adult immersion test (AIT). Tn LIT and AIT the toxicity of MLs was much higher than for LPT. In the AIT, diluting the injectable formulation of MLs in water was as effective as dilution in ethanol + Triton X-100. LC50, LC99.9 and 95% confidence limits were determined so that a discriminating dose (DD) could be set for larval and adult tests in order to diagnose potential resistance to MLs in field samples of the tick. These DDs are for Australian strains of B. microplus and may not be suitable for other strains until further work is carried out.The value of these diagnostic tests can only be verified if or when resistance to MLs emerges in ticks.

Locomotor and metabolic activities of Gymnostreptus olivaceus (Diplopoda, Spirostreptida) at different photoperiod conditions

In the present investigation the locomotor and the metabolic activity of Gymnostreptus olivaceus were studied, using 24-hr cycles at different photoperiods and constant temperature and RH. Locomotor activity was studied by the actography method and was reported as coefficients of nocturnalism [CN (N/N + D). 100]. The results showed a nocturnalism coefficient of 98,71% under normal photoperiod conditions and of 29,58% under inverted photoperiod conditions. In constant illumination, the CN of G. olivaceus was 88,22%, and in constant darkness, its rhythm was close to that of the normal photoperiod (CN = 94,92%). The metabolic activity was studied by manometric Warburg respirometry and lit was reported as mu l O-2 . g(-1). h(-1). The respiratory rate of G. olivaceus under normal photoperiod condition was higher at night than during the day (52,52 x 28,76), coinciding with the pattern of nocturnal locomotor activity of the animal. However, under conditions of inverted photoperiod, the millipede maintained its tendency toward a more intense nocturnal respiratory rate (50,35 x 39,14). Similar behaviours were observed under constant illumination and constant darkness, in which G. olivaceus again presented higher nocturnal respiratory rates than diurnal ones(85,84 x 53,48 and 73,18 x 57,0, respectively). The present experimental data suggests the persistence of an endogenous rhythm where the light may not be an important exogenous synchronizer of the activity of G. olivaceus, because it was insufficient to block the start of the biological clock and the natural tendency of higher nocturnal activities of millipedes, principally when the tests were performed in constant illumination or darkness (free-running tests).

Crystallization of piratoxin I, a myotoxic LYS49-phospholipase A(2) homologue isolated from the venom of Bothrops pirajai

Crystallization of piratoxin I, a myotoxic Lys49-phospholipase A(2) homologue isolated from the venom of Bothrops pirajai. Toxicon 36, 547-551, 1998.-Large single crystals of piratoxin I, a Lys49-PLA(2) homologue with low enzymatic activity, have been obtained. The crystals belong to the orthorhombic system space group p2(1)2(1)2(1) and diffract X-raps to a resolution of 2.8 Angstrom. Preliminary analysis reveals the presence of two molecules in the crystallographic asymmetric unit. (C) 1998 Elsevier B.V. Ltd. All rights reserved.

Histochemical and ultrastructural cytochemistry of glycogen on ovarioles of Neoponera villosa ants (Hymenoptera: Ponerinae)

In Neoponera villosa ants, we found ovaries of the polytrophic meroistic type which is characterized by the presence of nurse cells forming together with the oocyte, the so-called follicles. The nurse cells have the primary function of supplying the oocyte with RNA, but they contribute to the supply of other elements such as glycogen. With the objetive of detecting the presence of this substance in the ovarioles of workers and queens of N.villosa ante the ovaries were removed and processed according to electron microscopy technic for glycogen detection. Glycogen is a common element in insect oocytes and is abundantly distributed in the cytoplasm of N.villosa workers and queens. However, in ovarian follicles it can only be detected at stages ET and lit of development. Glycogen synthesis probably occurs predominantly in nurse cells which transfer it into the oocyte through the nourish pore. This process requires high energy expenditure that justify the large numbers of mitochondria associated with glycogen in the nurse cell cytoplasm. The amount of glycogen in the nurse cells of queens is slightly greater than workers.
