Microhabitat de Tolypothrix distorta Kütz. ex Bornet & Flahault (Microchaetaceae, Cyanophyta) em dois riachos da região Centro-Sul do Estado do Paraná, Brasil

This study aimed to evaluate some microhabitat characteristics of two populations of Tolypothrix distorta in streams from midsouthern region of Paraná State on a seasonal period. Each population was monthly investigated for the abundance of T. distorta and environmental variables such as depth, current velocity, irradiance, richness, and substrate diversity (H') using the quadrat technique for each sample unit (n = 7-10). For each segment the following physical and chemical water variables were also measured: temperature, oxygen saturation, specific conductance, pH, and turbidity. The seasonal period of higher abundance (percent cover) occurred during the months corresponding to summer/fall for both populations. The analyses also showed that populations had lower niche width and wide variation under the environmental conditions, characterizing the species as a generalist in the use of resources. Faster water flow and larger substrates favored the development of T. distorta, which may be related to the species morphological characteristics, thallus type that consists of tangled filaments formed by tuft and covered with thick gelatinous coats.

Application of two segmentation protocols during the processing of virtual images in rapid prototyping: ex vivo study with human dry mandibles

The aim of this study was to evaluate the accuracy of virtual three-dimensional (3D) reconstructions of human dry mandibles, produced from two segmentation protocols (outline only and all-boundary lines).Twenty virtual three-dimensional (3D) images were built from computed tomography exam (CT) of 10 dry mandibles, in which linear measurements between anatomical landmarks were obtained and compared to an error probability of 5 %.The results showed no statistically significant difference among the dry mandibles and the virtual 3D reconstructions produced from segmentation protocols tested (p = 0,24).During the designing of a virtual 3D reconstruction, both outline only and all-boundary lines segmentation protocols can be used.Virtual processing of CT images is the most complex stage during the manufacture of the biomodel. Establishing a better protocol during this phase allows the construction of a biomodel with characteristics that are closer to the original anatomical structures. This is essential to ensure a correct preoperative planning and a suitable treatment.

Documentação de fé: reflexões sobre os ex-votos e a sala das promessas do Santuário Nacional de Aparecida

This article brings to light a reflection about the possibility to enlarge the notion about document. Beyond the French school explanation, and taking up again important author of Information Science campus, the debates exposes within the Brazilian Catholic dimensions is possible to extrapolate the revision about the document’s idea, which is generally restrict to informational spaces. The National Sanctuary of Aparecida protects in a specific room the votive offerings – objects leaved there whether to pay a promise or to thank for any miracle that someone believes receive it. It is mediation’ space and it is can be thought as an environment, because there are possibilities to establish mediations inside it. Although, the room of the promises is a sacred and profane place, it involves a Cathequesis mission, expositive, informational, in spite of this last characteristic does not be explicit. First of all, the article reflects about the room of the promises and follows analyzing the document’s comprehension; in a second moment we finish purposing to understand the votive offering as a faith’s document, because they assume the position as proof of miracles and received graces, and these special objects brings with them a materiality positive and a documental value which the room fo the promises give to them.

As passagens do sagrado: da mercadoria ao ex-voto no Santuário Nacional de Nossa Senhora Aparecida/Brasil

This article reflects on the votive objects exhibited in the room of promises situated in the National Sanctuary of Nossa Senhora da Conceição Aparecida, located in the city named Aparecida (São Paulo, Brazil). At the sanctuary, there is an area to receive and exhibit votive offerings, which are donated as payment or to initiate a relationship of faith. This article’s aim is to understand how, from entering the room of promises, the votive object is selected and receives new directions, within the Sanctuary or outside it. Nonetheless, a small number are kept in this specific room dedicated to votive offerings. These objects become documents, social agents, because they reveal stabilization within associative relationships. With the help of readings from Information Science and other areas, and after carrying out ethnographic research over three years, this article shows how the materiality of information is indispensable for apprehending the relationship between society and information. Through contact with the votive offerings, the visitor establishes inferences, interpretations, which assist in comprehending the space, faith, and Nossa Senhora da Conceição Aparecida.

Expansão ex vivo de células uroteliais em scaffolds 3D

Malformations and possible damages to the urogenital system can be originated in the embryonic period. Moreover, fire guns, knives and accidents, where there is the disruption of the urethra, also cause these lesions. The objective was to analyze the contribution of tissue engineering in the construction of neo-urethra, developed by bioengineering. We performed an urothelial ex vivo expansion of cells in 3D scaffolds (platelet gel matrix and acellular porcine aorta) to assess the contribution of this technique in the construction of a neo-urethra. Mechanical dissociation was made of the inner wall of 10 North Folk rabbit’s bladder, weighing 2.5 to 3.0 kg. After dissociation the cell content was centrifuged and obtained a pellet of urothelial cells. The pellet was ressuspended in culture medium DMEM F12 and cells were maintained in culture for 15 days. Immunohistochemical analysis characterized the urothelial culture. The cells were then implanted in the scaffold - platelet gel. In a second experiment using aortic porcine acellular matrix were implanted urothelial cells alone and urothelial cells on platelet gel, on the inner wall of the scaffold - aorta, with space for setting bordered by a urethral probe. The complex probe - cells - aorta and probe - cells in platelet gel - aorta, were sealed with suture material and culture were maintained in a humidified 37ºC incubator with 5% CO2 in air for 12 days to subsequent histological analysis of urothelium cell adhesion to the scaffolds. By observation under an optical microscope, we could see the growth of cells in the scaffold platelet gel, from a monolayer in to a three-dimensional structure. In the acellular porcine aortic matrix containing the platelet gel, we could observe a few quantity of urothelial cells adhered. However with the acellular porcine aortic matrix in which was implanted only the urothelial cells, we have obtained adhesion to the wall

Efeito de reguladores vegetais no desenvolvimento de plantas jovens de Tabebuia avellanedae Lorentz ex Griseb

Tabebuia avellanedae Lorentz ex Griseb (ipê-roxo), Bignoniaceae, ocorre na Floresta Tropical Atlântica e é de grande importância, uma vez que, devido às suas propriedades medicinais e lenho de grande valor comercial, já esteve sob ameaça de extinção. A mistura de reguladores vegetais é conhecida como bioestimulante que pode incrementar o desenvolvimento vegetal, estimulando a divisão, a diferenciação e o alongamento celular. Assim, neste trabalho avaliou o efeito da aplicação da mistura de reguladores vegetais do grupo das auxinas, giberelinas e citocininas no desenvolvimento de plantas jovens de ipê-roxo. Os tratamentos foram: testemunha, GA4+7 + BAP 100 mg L-1, GA4+7 + BAP 200 mg L-1, GA3 + IBA + cinetina 0,5% e GA3 + IBA + cinetina 1,0% os quais foram aplicados 4 vezes em intervalos de 30 dias. O efeito dos tratamentos foi avaliado pelas medidas de altura das plantas, diâmetro do caule, número de folhas, massa seca das folhas, caule e raízes e avaliação de trocas gasosas. O tratamento com GA3 + BAP 200 mg L-1 foi aquele que apresentou maior efeito no crescimento das plantas. Já para as avaliações fotossintéticas o tratamento com GA3 + IBA + cinetina foi aquele que apresentou a maior taxa de assimilação de CO2
