Two new species of Pseudotelorchis (Digenea, Telorchiidae), parasites of the Caiman, Caiman crocodilus yacare (Reptilia, Crocodylia) from the Pantanal Mato-Grossense, Brazil

Pseudotelorchis caimanis n. sp. and P. yacarei n. sp. are described based on specimens collected from Caiman crocodilus yacare (Daudin) in the Pantanal Mato-grossense, Brazil. This is the first record of any species of Telorchiidae Stunkard, 1924, parasitizing crocodilians. Pseudotelorchis caimanis n. sp. differs from P. comapactus, the only species described in the genus with seminal receptacle, testes in tandem, and genital pore lateral to acetabulum. Pseudotelorchis yacarei n. sp. differs from the two other species for its body shape, for infecting the intestine instead of the uterus, by having regularly disposed instead of irregulary disposed uterine loops, and by having the vitelline glands disposed in longitudinal lateral lines instead of in lateral bunches.

Estimates of genetic parameters for fruit yield and quality in custard apple progenies

Apparently, there are no custard apple cultivars defined for the northeastern region of Brazil. The establishment of breeding programs aimed at the selection of types from productive locations for later cloning is desirable. This work's objective was to evaluate the yield (during the first three crops) and quality (first crop) of fruits from 20 half-sibling custard apple tree progenies, selected from home orchards. An additional objective was to estimate genetic parameters for the traits evaluated. A micro sprinkling-irrigated experiment was conducted in Mossoró-RN, Brazil, as random blocks with five replications. In characteristics evaluated for periods longer than a year (diameter, height and mean weight of fruits, number of fruits ha-1 and fruit yield (kg ha-1), and a split-plot design was adopted, with progenies considered as plots and annual cropping seasons as subplots. The best progenies in terms of fruit yield (A3 and A4) are not necessarily the best for fruit dimensions and fruit mean weight (A2, FE4, JG1, JG2, SM1, SM7, and SM8). These progenies show great potential to be used in future studies on crosses or on vegetative propagation. In this regard, progeny JG2 should be highlighted as promising in terms of yield and fruit size. The progenies are not different with regard to percentages (in relation to mean fruit mass) of pericarp, endocarp, seeds, and receptacle, in the fruit, and fruit volume, number of seeds/fruit, and total soluble solids content in the fruit pulp, but progeny FE4 presents higher total titratable acidity in the fruit pulp. Narrow-sense heritability estimates were relatively high for all characteristics in which there was variability between progenies, with higher values for number of fruits ha-1 (80 %) and fruit yield (78 %). Relatively high coefficients of genotypic variation (around 20%) were observed for number of fruits ha-1 and fruit yield, with lower values for the other characteristics. There were positive genotypic and phenotypic correlations between fruit diameter (FD) and fruit height, FD and mean fruit weight, and number of fruits ha-1 and fruit yield.

Cioran ou le mal de foi : les vestiges du sacré dans l'écriture

Le rapport occidental moderne au sacré s’est transformé de façon importante au 20e siècle avec le processus de sécularisation. Cette désagrégation d’un sacré traditionnel laisse un vide – principalement existentiel et spirituel – là où auparavant certains contenus associés au sacré permettaient de se positionner dans et face à l’universel, c’est-à-dire d’occuper une place dans le monde et les institutions qui l’organisent et d’investir cette place d’un sens compris, accepté et partagé autant individuellement que collectivement. De toute évidence, un tel processus d’effritement ne s’opère pas sans restes et la littérature est un espace qui recueille ces vestiges d’un sacré en transformation, d’un sacré qui fait l’objet d’une quête. L’écriture de Cioran représente un lieu exemplaire où sont concentrés ces vestiges et elle est aussi l’outil ou le médium par lequel la quête s’effectue. Son écriture tiraillée, pétrie d’un malaise existentiel et d’un doute profond, témoigne d’un refus, pensé comme une incapacité, à souscrire aux visions traditionnelles, surannées, du sacré. Généralement considérée par la critique comme inclassable – ni tout à fait philosophique, ni tout à fait littéraire – l’œuvre de Cioran souligne pourtant l’importance de la littérature comme modalité de l’esprit. Cette œuvre met en lumière le rôle de la littérature pour la pensée dans la mesure où elle est un espace qui permet d’accueillir la pensée en quête d’un sacré hors-cadre, en même temps qu’elle se fait le moyen d’une recherche plus libre, plus personnelle, du sacré. La littérature devient donc le réceptacle autant que le moyen d’une quête pleinement existentielle, une quête qui n’est ni représentée ni confessée, mais bien mise en scène, c’est-à-dire dramatisée. Le « je » qu’on retrouve partout dans l’œuvre de Cioran n’est pas le « je » d’une confession, mais bien un « je » narratif qui n’équivaut pas au « je » de l’écrivain. C’est précisément dans le décalage lié à la dramatisation qu’apparaît le paradoxe propre au savoirparticulier que porte la littérature: soit ce caractère personnel, incarné, particulier qui devient le véhicule d’une expérience universelle dans la mesure où elle a le pouvoir ou le potentiel d’abriter l’expérience personnelle d’un lecteur qui performe, pour lui-même, le texte. En ce sens, écriture et lecture sont """! imbriquées, comme deux faces d’une même réalité, dans cette quête d’un sacré qui se produit chez Cioran dans un espace d’exception, en dehors des institutions. À partir de l’exemplarité de l’œuvre cioranienne, cette thèse propose une réflexion qui porte sur la littérature comme mode d’inscription des vestiges du sacré ainsi que comme manifestation et moyen d’une quête d’un sacré débarrassé des balises institutionnelles, et qui tente de mettre en lumière le type de savoir propre à la littérature sous l’angle précis de la dramatisation littéraire dans le contexte particulier de cette quête.

Les processus de la mise en scène : polyphonie et complexité dans la création scénique

Les processus de la mise en scène reposent nécessairement sur une réalité humaine complexe, faite de dialogues et de rapports de force en constante redéfinition. Afin de les théoriser, plusieurs travaux ont institué en corpus les documents produits en cours de réunion ou de répétition, pour leur appliquer les méthodes issues de la génétique des textes. Or le transfert s’avère problématique : vestiges lacunaires, ces supports ne sauraient témoigner à eux seuls de la vie organique et polyphonique de la mise en scène en gestation. Une première solution consiste à opter pour une approche radicalement intermédiale des archives d’un spectacle : dans la mesure où la mise en scène fait interagir plusieurs disciplines artistiques, pourquoi ne pas la penser en confrontant activement les différents media générés lors de son élaboration ? Complémentaire de la première, une seconde proposition suppose que le chercheur s’implique dans une observation in vivo de réunions et de répétitions afin de disposer d’une matière plus complète. À cette clarification épistémologique succède un essai de théorisation des processus de la création scénique. Il apparaît tout d’abord que l’espace de travail est aussi bien un contenant physique de la recherche des artistes qu’un catalyseur : c’est en se l’appropriant à plusieurs qu’un groupe de collaborateurs donne corps à la mise en scène. L’espace de création révèle par là même une dimension polyphonique que l’on retrouve sur le plan du temps : dans la mesure où il engage un ensemble d’artistes, un processus ne possède pas de linéarité chronologique homogène ; il se compose d’une multitude de temporalités propres à chacun des répétants, qu’il s’agit de faire converger pour élaborer un spectacle commun à tous. Les processus de la mise en scène se caractérisent ainsi par leur dimension fondamentalement sociale. Réunie dans un espace-temps donné, la petite société formée autour du metteur obéit à un mode de création dialogique, où les propositions des uns et des autres s’agrègent pour former un discours foisonnant dont la force et l’unité sont garanties par une instance surplombante.

A SEPALLATA gene is involved in the development and ripening of strawberry (Fragaria X ananassa Duch.) fruit, a non-climacteric tissue

Climacteric and non-climacteric fruits have traditionally been viewed as representing two distinct programmes of ripening associated with differential respiration and ethylene hormone effects. In climacteric fruits, such as tomato and banana, the ripening process is marked by increased respiration and is induced and co-ordinated by ethylene, while in non-climacteric fruits, such as strawberry and grape, it is controlled by an ethylene-independent process with little change in respiration rate. The two contrasting mechanisms, however, both lead to texture, colour, and flavour changes that probably reflect some common programmes of regulatory control. It has been shown that a SEPALLATA(SEP)4-like gene is necessary for normal ripening in tomato. It has been demonstrated here that silencing a fruit-related SEP1/2-like (FaMADS9) gene in strawberry leads to the inhibition of normal development and ripening in the petal, achene, and receptacle tissues. In addition, analysis of transcriptome profiles reveals pleiotropic effects of FaMADS9 on fruit development and ripening-related gene expression. It is concluded that SEP genes play a central role in the developmental regulation of ripening in both climacteric and non-climacteric fruits. These findings provide important information to extend the molecular control of ripening in a non-climacteric fruit beyond the limited genetic and cultural options currently available.

Fertilidade do caranguejo de mangue Ucides cordatus (Linnaeus) (Crustacea, Brachyura, Ocypodidae), em Iguape (São Paulo, Brasil)

A total of 58 Ucides cordatus (Linnaeus, 1763) ovigerous females in final embryonic stage were collected in mangrove forest at Iguape (São Paulo). Each female were kept in laboratory until the larvae hatching and had their carapace width (CW) measured with caliper (0.05 mm) and the larval number (LN) calculated by volumetric method. The hatching rates (HR) were calculated for each animal's size class (5 mm). The values of LN and CW obtained were subjected to regression analyses and the best fitting model was chosen by comparing the obtained determination coefficients (R²). The fertility varied from 71,200 to 220,800 larvae (147,169 ± 32,070 larvae), corresponding to 41.7 to 76.8 mm CW (63.7±7.9 mm), respectively. The relationship LNxCW was expressed by the equation LN = 284.1CW1.5º¹ (N = 58; R² = 0.74; p < 0.01), that showed a positive correlation between the variables. Most part of ovigerous females (89.7%) showed their hatching during the nightly period. A negative correlation between HR and CW was observed in these animals (p < 0.05), probably due to reduction of spermatophores in the seminal receptacle (multiparous females) or due to senility in the females with large size. The biological studies of U. cordatus are very important for practices adoption that preserve and make the rational use of this recourse in Brazilian's mangrove forests.

g-acceleration of gravity: its measurement from the shape of water by using a computerized rotational system

This paper proposes a different experimental setup compared with the traditional ones, in order to determine the acceleration of gravity, which is carried out by using a fluid at a constant rotation. A computerized rotational system-by using a data acquisition system with specific software, a power amplifier and a rotary motion sensor-is employed in order to evaluate the angular velocity and g. An equation to determine g is inferred from fluid mechanics. For this purpose, the fluid's parabolic shape inside a cylindrical receptacle is considered using a rotational movement.

Floral anatomy of Eriocaulon elichrysoides and Syngonanthus caulescens (Eriocaulaceae)

The floral anatomy of Eriocaulon elichrysoides Bong. and Syngonanthus caulescens (Poir.) Ruhland, from Brazilian mountain rock savannas (campos rupestres) was studied. The staminate flowers of E. elichrysoides present a diplostemonous androecium with six stamens, and those of S. caulescens present an isostemonous androecium with three stamens and three scalelike staminodes. Eriocaulon elichrysoides and S. caulescens have three nectariferous pistillodes located in the central portion of the receptacle. The pistillate flowers of E. elichrysoides present three simple styles while those of S. caulescens present three simple styles interspersed with three nectariferous appendices. Both the styles of E. elichrysoides and the nectariferous appendices of S. caulescens are vascularized by the dorsal vascular bundles of the carpels. The styles of S. caulescens lack vascularization. At the base of the gynoecium of E. elichrysoides there are six staminodes and there are three in the S. caulescens. Entomophily is suggested as the pollination syndrome in E. elichrysoides and S. caulescens as they present staminate and pistillate flowers with nectariferous structures. The ancestral character in Eriocaulon is probably given by the presence of the two staminal whorls. The staminate flowers of S. caulescens are probably derived from the reduction of a diplostemonous ancestral androecium. It remains open whether the pistillate flowers with nectariferous, appendices present an ancestral character or a derived one.

Limpeza do forame e extrusão apical de raspas de dentina em dentes unirradiculares submetidos ao procedimento de patência apical

Objective: To verify the cleaning of the apical foramen and apical extrusion of dentin chips in single-rooted teeth instrumented with two techniques, one of which including the apical patency procedure. Method: Thirty teeth were internally stained with Indian ink, divided in two groups, of which only group I was subjected to apical patency. The dentin chips extruded through the apical foramen were collected in a glass receptacle and quantified. The apical foramen region was divided in quadrants and analyzed with a stereomicroscope to verify the action of the instrument on the cemental canal walls. The teeth were scored 0 4 according to the number of clean walls (without Indian ink), 0 corresponding to no clean wall. Results: In group I, there was no dentin plug, but only 1 tooth was scored 4. In group II, 10 teeth presented dentin plug and all of them were scored 0. There was no statistically significant difference between groups I and II regarding the extruded dentin mass (Scheffé test; p<0.05). Conclusion: The use of the apical patency procedure in single-rooted teeth does not modify the amount of dentin chips extruded through the apical foramen, does not produce an adequate cleaning of the cemental canal walls, but remove the plug of dentin chips from the cemental canal.

Avaliação clínica e microbiológica do tratamento da estomatite protética com tintura de Schinus terebinthifolius Raddi (Aroeira)

Objective: To evaluate the clinical efficacy of Schinus terebinthifolius Raddi (aroeira) tincture in the treatment of denture stomatitis. Method: Eighteen removable denture wearers with clinical diagnosis of type II denture stomatts and presence of candidosis associated to the denture use, as confirmed by clinical and mycological examinations, were selected for the study. The patients were allocated to two groups: TG (test group) - treatment with Schinus terebinthifolius Raddi (aroeira) tincture; CG (control group), treatment with nystatin. All patients were instructed to clean the dentures with toothbrush and dentifrice, and then apply the product on the palatal mucosa and on denture surface 3 times a day, during 15 consecutive days, removing the denture at bedtime and keeping it in a receptacle with water. At the 15th day of use, the clinical and mycological examinations were redone to evaluate treatment efficacy. Data were analyzed statistically by Wilcoxon and Mann-Whitney tests at 5% significance level. Results: The inflammatory process and Candida spp. infect on were eliminated in 66.7% and 77.8% of the cases, respectively, in TG. In CG, elimination of the inflammatory process and fungal infect on occurred in 77.8% and 88.9% of the cases, respectively. These results were statistically significant (p=0.01). There was no statistically significant difference between the treatments (p>0.05). In all cases, fungal infect on was detected only on the denture, and C. albicans was the most prevalent microorganism, being present in 94.4% of the cases. Conclusion: The treatment with Schinus terebinthifolius Raddi (aroeira) tincture was effective in the treatment of denture stomatitis, promoting remission of the inflammatory process and Candida spp infection.

Development of the male reproductive system in Callinectes ornatus Ordway, 1863 (Brachyura: Portunidae)

This study describes the histology and histochemistry of the male reproductive system in Callinectes ornatus, comparing juvenile and adult developmental stages. We also analyzed changes in the gonadosomatic (GSI) and hepatosomatic (HSI) indices, and the weights of the testis and vas deferens during the development. The results showed that all stages, beginning with the juvenile (JUV), through developing (DEV) and mature (MAT) adult males of C. ornatus produce sperm and spermatophores. During development, testicular lobes showed the same characteristics of production and release of sperm into the seminiferous duct. The vas deferens showed little histological and histochemical change in the epithelium in juvenile and adult males. The differences consisted of the larger amount of secretion in MAT males compared to JUV and DEV ones. The chemical composition of the seminal fluid was similar, but MAT males produced a more homogeneous secretion. Morphological and physiological maturation are not synchronized in C. ornatus, since JUV males produced spermatophores similar to those in DEV and MAT males. However, these JUV are not yet able to reproduce, since they still have the abdomen attached to the cephalothoracic sternum. The increase of the GSI during development was significant for MAT males, and is related to the production of sufficient volume of seminal fluid to form the sperm plug in the female seminal receptacle. The HSI decreased from DEV to MAT adult stages, indicating that reserves from the hepatopancreas are used to develop the reproductive system after the pubertal molt.
