Aspectos clínicos, histopatológicos e moleculares da dermatosparaxia em ovinos White Dorper

Dermatosparaxis in animals is an autosomal recessive disorder of the connective-tissue clinically characterized by skin fragility and hiperextensibility. The disease in White Dorper sheep is caused by mutation (c.421G>T) in the ADAM metalloproteinase with thrombospondin type 1 motif, 2 (ADAMTS2) gene. This study describes the dermatological, histological and the molecular findings of the dermatosparaxis in White Dorper sheep from a herd located in the center-west of São Paulo State. The herd consisted of one ram, four ewe and their lambs. In this herd two lambs had clinical signs consistent with dermatosparaxis. Histopathological evaluation of the affected skin of these two animals also revealed consistent findings with dermatosparaxis, characterized by dysplasia of the collagen, which were arranged in small and fragmented collagen bundles and with foci of degeneration of collagen. Prominent cutaneous appendages and severe hemorrhagic focus in dermis region associated with mild neutrophilic infiltrate in the deep dermis. PCR using DNA blood and specific primers to amplify the mutation region c.421G>T was optimized in order to perform molecular diagnosis of the disease. The direct sequencing of the PCR products proved that the two clinically affected animals had the mutation responsible for dermatosparaxis, previously described for this breed and allowed the definitive diagnosis of the disease. This is the first report of the dermatosparaxis in White Dorper sheep in Brazil and the methodology used to confirm the diagnosis could be used in future studies to assess the prevalence of this mutation in Brazil, allowing the adoption of measures to prevent the spread of this mutation in the Brazilian White Dorper herd.

Anatomia floral de espécies de Bulbophyllum sect. Micranthae (Orchidaceae, Asparagales)

Bulbophyllum, which comprises 1876 species, is considered the second largest genus of angiosperms, with a pantropical distribution. The morphological and anatomical floral studies in the genus are incipient, with data restricted to the gynostemium and lip of some species. Based on molecular data, six sections were recognized within Bulbophyllum at the Neotropics, amongst them Bulbophyllum sect. Micranthae, which comprises 12 species distributed in central South America. We aimed to study the floral anatomy of six species of Bulbophyllum sect. Micranthae, in order to determine useful characters to differentiate them and contribute to the anatomical characterization of the section as a whole. Floral anatomy was assessed through usual techniques of light microscopy. The data found here for B. adiamantinum, B. chloroglossum, B. epiphytum, B. mentosum, B. micranthum and B. rupicolum allowed to identificate the presence of glandular trichomes and the possible presence of a secretory region on the lip, which might produce substances used as a reward to pollinators. The most significant anatomical characters to the species characterization were the shape and ornamentation of the outer periclinal walls of the epidermal cells, as well as the number of vascular bundles in dorsal and lateral sepals and at the lip. The data also allowed the differentiation between B. epiphytum and B. rupicolum, species very similar in morphology and phylogenetically related. Besides that, the data also allowed the discussion regarding the maintenance of B. mentosum within the section: although its inclusion is supported by molecular studies, the anatomical data here presented shows greater differences compared to the other species, not supporting its maintenance in Bulbophyllum sect. Micranthae

Proposta de um processo de categorização de fornecedores para a execução de projetos

Nowadays, in business environment, organizations seek to differentiate through special programs and plans, taking the concepts of sustainability, performance and benefits generated for society. Based in this competitive environment, as companies depend on the use of subcontractors to perform services for your different customers, the work performed by them is directly related to the vision created by the final customer’s vision of the company responsible for the project. Considering that the supplier hired to execute the project does not share the strategic concepts related to the level of services to be offered to the final customers, thus creating the need to develop methods that enable the alignment between the project owner, responsible for preparing the executive project, and the supplier, responsible for the execution of the work. Tangent to this need, it was necessary to create a method of evaluation and categorization for suppliers to hired for the projects. As a result it has been proposed a process of categorization of suppliers, through the restriction of possible companies to be hired for a project designed to promote alignment between strategies and continuous improvement of the solutions offered to the market

Radioterapia em câncer de mama: importância da determinação da curva de isodose

The study analyzed contours of the thoracic region of patients undergoing radiotherapy of breast tumors in Hospital Manuel de Abreu of Bauru (institution 1) and the Hospital da Faculdade de Medicina of Botucatu (Institution 2). Were prepared isodose curves corresponding to the contours of the patient, which were presented for radiotherapists doctors both hospital services that enabled the choice of the curve isodose that provides the best distribution of radiation dose in the irradiated volume. Some boundaries were digitized in one institution and sent for preparation of isodose lines in the institution 2, both curves plotted in each of the institutions and for the same contour, were compared, showing that the methodology of Curves of distance is feasible and reliable, while optimizing the routine procedures regarding the handling of isodose plans provided by different radiation equipment. It compares the calculation of the exposure time determined using the isodose curve selected by calculating the value obtained considering the PDP at the point of the middle line of separation between the internal and external fields, the difference between the two methods for determining exposure time was around 2.4%. A study on the angle of the radiation beam at the input field (region breast-air) was conducted showing that, once known a tangent angle of the input beam, one can estimate the angle of the wedge filter used in some procedures for uniformity of dose within the irradiated volume compensation and the lack of tissue in the treatment volume. A comparative study between the isodose curves produced manually with the curves obtained in a two-dimensional computer system, the computer system showed that provides further information regarding the dose gradient within the irradiated volume, in addition to reducing the time spent in preparing the curves isodose

Análise da influência da concentração de feixeis de fibras de bambu em ensaios de piso

Bamboo has one of the highest growth rates among plants, however, its lignifications (which confers resistance) takes around a few years and, therefore, certain physical characteristics and mechanical, that depend on this process will only be acquired between the three to six years old. In addition, bamboo also has significant density variations in different parts of the stem, both in the radial direction as the axial. In particular the radial direction, where the density found in the inner and outer (near the bark) of a single stem can range on average from 0.5 to 0.9 g/cm3. Thus, the application of bamboo as a floor, there to examine whether both sides of the bamboo (internal and external), provide resistance properties required for that purpose. In this study sought to characterize and quantify the influence of the concentration of fiber bundles in the inner and outer sides of rules or bamboo strips of bamboo flooring through testing service. Analyses performed were based on ASTM D 2394- 83 for wooden floors and derivatives. This was necessary because of the absence of a specific prohibition of the use and testing of floors made of bamboo and its products. The data were analyzed by ball indentation test shooting, test for resistance to abrasion, indentation test for stress / load treadmill test and by indentation loads applied to small areas - test the jump. The results of the tests were extremely friendly bamboo, even this presents considerable differences between the resistances obtained from assay of the cover of the inner and outer face, being comparable with those of many commonly used to manufacture wood flooring. This comparison was made possible by information from technical trials of several floors made with wood

Involutions whose fixed set has three or four components: a small codimension phenomenon

Let T : M → M be a smooth involution on a closed smooth manifold and F = n j=0 F j the fixed point set of T, where F j denotes the union of those components of F having dimension j and thus n is the dimension of the component of F of largest dimension. In this paper we prove the following result, which characterizes a small codimension phenomenon: suppose that n ≥ 4 is even and F has one of the following forms: 1) F = F n ∪ F 3 ∪ F 2 ∪ {point}; 2) F = F n ∪ F 3 ∪ F 2 ; 3) F = F n ∪ F 3 ∪ {point}; or 4) F = F n ∪ F 3 . Also, suppose that the normal bundles of F n, F 3 and F 2 in M do not bound. If k denote the codimension of F n, then k ≤ 4. Further, we construct involutions showing that this bound is best possible in the cases 2) and 4), and in the cases 1) and 3) when n is of the form n = 4t, with t ≥ 1.
