Studies related cryptosporidiosis will be essential, due to its relevance in public health and pathogenicity in pets and production animals. Over the past 20 years, there has been a rapid expansion of research involving the Cryptosporidium genus, largely related to molecular studies, providing a description of various species, genotypes and subtypes of the parasite. The molecular characterization of isolates from different sources (human, animal and environmental) has been widely used in order to investigate the potential zoonotic of this protozoa. The documented transmission forms from animals to humans, from person to person, through water intake or water for the leisure that are directly or indirectly contaminated with sporulated oocysts. The high rate of animals naturally infected and the susceptibility by protozoan, justify the importance of attending to the occurrence of this disease. So are demonstrated epidemiological aspects of this zoonotic disease in domestic animals.

Patients with neurological disorders have an increased risk of oral and systemic diseases due to compromised oral hygiene. If patients lose the ability to swallow and chew food as a result of their disorder, enteral nutrition is often utilized. However, this type of feeding may modify salivary antioxidant defenses, resulting in increased oxidative damage and the emergence of various diseases. The aim of this study was to evaluate the effects of enteral nutrition on biochemical parameters in the unstimulated whole saliva composition of patients with neurological disorders. For this, enzymatic (superoxide dismutase - SOD; glutathione peroxidase - GPx) and non-enzymatic (uric acid; ferric ion reducing antioxidant power - FRAP) antioxidant activity, as well as a marker for oxidative damage (thiobarbituric acid reactive substances - TBARS) were analyzed. Unstimulated whole saliva was collected from 12 patients with neurological disorders and tube-feeding (tube-fed group - TFG), 15 patients with neurological disorders and normal feeding via the mouth (non-tube-fed group - NTFG), and 12 volunteers without neurological disorders (control group - CG). The daily oral hygiene procedures of TFG and NTFG patients were similar and dental care was provided monthly by the same institution's dentist. All patients exhibited adequate oral health conditions. The salivary levels of FRAP, uric acid, SOD, GPx, TBARS, and total protein were compared between studied groups. FRAP was increased (p < 0.05) in the NTFG (4651 +/- 192.5 mmol/mL) and the TFG (4743 +/- 116.7 mmol/mL) when compared with the CG (1844 +/- 343.8 mmol/mL). GPx values were lower (p < 0.05) in the NTGF (8.24 +/- 1.09 mmol/min/mg) and the TFG (8.37 +/- 1.60 mmol/min/mg) than in the CG (15.30 +/- 2.61 mmol/min/mg). Uric acid in the TFG (1.57 +/- 0.23 mg/dL) was significantly lower than in the NTFG (2.34 +/- 0.20 mg/dL) and the CG (3.49 +/- 0.21 mg/dL). Protein was significantly lower in the TFG (5.35 +/- 0.27 g/dL) than in the NTFG (7.22 +/- 0.57 g/dL) and the CG (7.86 +/- 0.54 g/dL). There was no difference in the salivary flow rate and SOD between groups. Enteral nutrition in patients with neurological disorders was associated with lower oxidative damage, resulting in increased salivary. antioxidant capacity. These results emphasize the importance of oral care for this population to prevent oral and systemic diseases. (C) 2014 Elsevier Ltd. All rights reserved.

Mesenchymal stem cells (MSCs) are a heterogeneous population of cells that proliferate in vitro as plastic-adherent cells, have fibroblast-like morphology and can differentiate into bone, cartilage and fat cells. Therapeutic potential of MSCs have been studied in experimental models, such as rabbit, in Laboratory of Cell Engineering of Botucatu. However, no specific markers have been reported for expanded rabbit MSCs, which hampers the isolation of pure MSC populations by immunophenotypic characterization. Thus, the objective of this study was to produce monoclonal antibodies (mAbs) to rabbit MSCs. MSCs derived from rabbit bone marrow (BM) were isolated, cultured, expanded ex vivo, and immunized into three BALB/c mices, and spleen cells subsequently harvested were used to generate hibridoma cell lines secreting antibodies against MSCs. Hybridoma cells were screened by flow cytometry and antibody-producing cells were subjected to subsequent rounds of retests. MSC1-160 obtained the best positivity for IgG expression and was cloned by limiting dilutions and micromanipulation. Ascitic fluid from ten best clones was purified by affinity chromatography in Protein A-sepharose CL-4B column and purification control was performed by electrophoresis in agarose gels. The purified IgG were tested against rabbit MSCs, obtaining high positivity by flow Cytometry. In conclusion, we developed 10 mAbs, MSC1-160 A20, A30, A41, A47, A55, A60, A63, A69, A81, and A82, that recognize rabbit MSC cell surface antigens showing potential for immunophenotypic characterization of rabbit MSC cell lines

The present work has the scope to show the relationship between four three-dimensional waves. This fact will be made in the form of coupling, using for it the Cauchy-Riemann conditions for quaternionic functions [#!BorgesZeMarcio!#], through certain Laplace's equation in [#!MaraoBorgesLP!#]. The coupling will relate those functions that determine the wave as well as their respective propagation speeds.

The aim of this article is to present some considerations on the contemporary city figurativizations, from the reading of “O Arquiteto”, a Bernardo Carvalho’s short story, published in the anthology “Aberração” (2004). In this short story, the writer retakes the city theme following a modernity tradition, established, among others, by Poe and Baudelaire, making his voice embrace other Brazilian writers voices, that have represented the town, but, at the same time, recreating, in his scripture body, dense and intense, quick and, in some sense, agonic, the utopist projects of renascence ideal cities, questioning the utopias and the aesthetics traces which can be found on the nowadays texts. To enlarge the metalinguistic proposal that emerges from the analysis, some poems by João Cabral de Melo Neto are considered. This comparison allow us to establish parameters to think about influence in certain perspective of contemporary literature, which epicenter configures less the supremacy of the newty and more a aesthetic of deletions of the origins, tracks, traces, which are possible by the canon invention.

The critic João Alexandre Barbosa, points in the work Agrestes (1981-1985), of the Brazilian poet João Cabral de Melo Neto, the presence of individualized death. Thus way, this study proposes to analyse the meanings of lyrism and first-person enunciations, in the work Agrestes, a trace gradually eliminated from Cabral’s discursive field since his first work, Pedra do Sono (1940-1). These elements will clash with João Cabral’s poetics, previously based on the selection of voices and artistic practices consistent with his compositional method, with rigorous sorting values and elimination of any subjectivism. To understand this inconsistency, we propose studying the last part of the work Agrestes, entitled “A indesejada das gentes”, a place where the theme of death is recurrent, as well as the presence of enunciators to set out, even to reveal its feelings about aging and death. The analytical procedure should research the hypothesis of rupture of the inflexible tone of João Cabral’s speech that would follow in respect to the poetic project, a reverse path, starting from objective poetry in the direction of subjective poetry.

The aim of this study was to evaluate the surface roughness of 5 indirect restorative materials treated with hydrofluoric acid to 10%, with aluminum oxide jet and a combination of both. The specimens was prepared with 10 mm in diameter and 2 mm thickness, divided into fi ve groups: (1) Ceromer (CeseadII-Kuraray), (2) Leucite crystals ceramics (IPS EmpressIIIvoclarforcasket), (3) glass ceramic with fluorapatite (IPS D. Sign-Ivoclar), (4) lithium disilicate ceramic (IPS Empress II-Ivoclar restorations), (5) ceramics (Cergogold-Degussa). For all groups were performed the controls, and the surfaces with the 3 types of treatment. For testing roughness used the rugosimeter Taylor/Hobson-Precision, model form tracerSV-C525 high sensitivity. After confi rmation of variance analysis with a signifi cance level of 1% (p < 0.01), there was equality between the average roughness of materials from groups 1, 3 and 5, and the group 2 was different from the others. It was also found that the ceramics of the group 5 behaved similar to group 4. However the lowest average roughness was observed in group 2 ceramic. In the evaluation between the types of treatment, the aluminum oxide jet and associations and blasting with hydrofl uoric acid were similar, and different isolated hydrofl uoric acid, and 3 types of treatment signifi cantly higher than the control group. All treatments promoted superfi cial alterations in all tested materials.

This study evaluated the effect of Er,Cr:YSGG laser irradiation on the external adaptation of composite resin restorations in caries-affected cavities. Mixed class V cavity preparations were performed in 36 intact human third molars, in half of which caries was artificially induced. Both healthy and carious dentin were etched with 35% phosphoric acid (Ultradent Products Inc., South Jordan, Utah, USA), and the teeth were divided into three groups, i.e., (a) untreated etched dentin, (b) application of the Er, Cr:YSGG laser and (c) use of chlorhexidine as an adjunct in the bonding process. Restorations were fabricated with Z350 XT FiltekTM composite resin (3M ESPE) and subsequently the specimens were subjected to thermocycling to simulate artificial ageing. Quantitative analysis of external adaptation was performed by scanning electron microscopy in both healthy and affected dentin using epoxy resin replicas. It was concluded that the application of laser and chlorhexidine did not affect the percentages of marginal adaptation of class V restorations. Furthermore, thermocycling may influence adaptation values.

The composite resin is the material of election for direct restorations in posterior teeth currently. The restorative dentistry aims to improve each day the material and facilitate the restorative technique. This paper describes the technique of occlusal matrix made to speed up and preservation the occlusal surface of a first molar tooth affected by caries lesion. A new resin-based composite was used called Silorane, which may be placed in larger increments due the material has low shrinkage and polymerization stress. The use of occlusal matrix associated with a low shrinkage resin composite can simplify the clinical work, and result in a restoration with excellent reproduction of anatomical.
