title: The relationship between attitude and success of written correction feedback in the acquisition of a second language

description: ABSTRACT This paper reports part of a doctoral dissertation that investigated learner attitudes towards written corrective feedback (CF) in a second language (L2). Attitude was measured with a questionnaire that used a 5-point Likert scale. Preferences were measured in percentages per question and the correlation between attitude and the effect of CF using Pearson correlation index. In adition, to determine more accurately the statistical relationship between attitude and the effect of CF, a repeated measures analysis of covariance with attitude as covariate was performed. The results indicate that students prefer to be corrected in the production of texts in English as a second language and that attitude can mediate the effect of CF.

title: Accuracy of the defining characteristics in nursing diagnoses of Hyperthermia in newborns

description: ABSTRACT Objective: to clinically validate the accuracy of the defining characteristics in nursing diagnoses of Hyperthermia in newborns. Method: a cross-sectional study conducted in units of medium and high risk in a maternity from the city of Fortaleza-CE. A total of 216 newborns were evaluated to identify the defining characteristics of diagnoses. A latent class model with random effects was used to measure sensitivity and specificity. Results: Hyperthermia was present in 5.6% of the sample. The characteristics lack of suction maintenance (31.3%); skin warm to touch (25.5%); lethargy (24.2%); and tachypnea (21.4%) were the most frequent. Stupor presented higher sensitivity (99.9%) and specificity (100%) while vasodilation characteristics, irritability and lethargy only showed significant values for specificity (92.7%, 91.6% and 74.3%, respectively). Conclusion: four characteristics of high specificity contribute to Hyperthemia. However, stupor is the only one with significant sensitivity to identify it at its early-stage.

title: Black and white teas as potential agents to combine with amphotericin B and protect red blood cells from amphotericin B-mediated toxicity

description: Abstract Amphotericin B is a fungicidal substance that is treatment of choice for most systemic fungal infections affecting immunocompromised patients. However, severe side effects have limited the utility of this drug. The aim of this study was to evaluate the antifungal effect of the combination of amphotericin B with black tea or white tea and protective of citotoxic effect. The present study shows that white and black teas have additive effects with amphotericin B against some species Candida. In addition, the combination of white and black tea with amphotericin B may reduce the toxicity of amphotericin B to red blood cells. Our results suggest that white and black tea is a potential agent to combine with amphotericin for antifungal efficacy and to reduce the amphotericin dose to lessen side effects.

title: Effect of irrigation at critical stages on the phenology of flowering and fruiting of the cactus Opuntia spp.

description: Abstract This paper briefly reports some effects of irrigations at two critical periods on the phenology of three varieties of cactus pear cultivated in Agadir area: the spineless varieties ‘Aissa’ and ‘Moussa’ and the thorny one ‘Achefri’. In the first year experiments (2010-2011) treatments of irrigation used were: (T1) 0 mm, (T2) 30 mm during flowering and 30 mm during fruit enlargement and (T3) 30 mm only during fruit enlargement. In the 2nd year experiments, irrigation treatments were: (T1) 0 mm, (T2) 60 mm during flowering and 60 mm during fruit enlargement and (T3) 60 mm only during fruit enlargement. Treatments of irrigation were applied between mid-April and mid-June in the 1st year experiments and in February and May in the 2nd year experiments. Results of the first year experiments showed that the emission of buds was higher in the thorny variety than in the spineless ones (more than 6 emitted buds/cladode vs less than 4.5 in the spineless varieties). In the second year, irrigation increased the emission of buds in the three varieties (more than 7 emitted buds/cladode for each T2 and T3 of all varieties vs not more than 5 for T1) and the duration of the flowering phase of these varieties. However, irrigation did not modify the proportions of fruits reaching commercial maturity during the early or the late period of maturation.

title: Susceptibility of cariogenic microorganisms to phytoconstituents

description: Abstract This study aimed to evaluate the in vitro antibacterial activity of the phytochemicals thymol, linalool, and citronellol against Streptococcus mutans, Streptococcus salivarius and Streptococcus oralis. Disk diffusion screening on solid medium and measurement of the diameter of the bacterial growth inhibition halos was the technique utilized. The Minimum Inhibitory Concentration (MIC) of the substances was determined using serial substance dilutions and microdilution technique in Brain Heart Infusion culture medium. After incubation for 24 hours in an oven at 37 °C, plate reading was completed and confirmed by visual method using 2,3,5 triphenyl tetrazolium chloride dye. The Minimum Bactericidal Concentration (MBC) was determined from MIC subcultures. Assays were performed in triplicate, and chlorhexidine was used as a positive control. The diameters in mm of the growth inhibition halos ranged between 7.3 and 10.7 for S. mutans, 7.3 and 10.0 for S. oralis, and 8.2 and 9.8 for S. salivarius. The MIC and MBC values obtained converged, ranging from maximum values in the presence of Linalool (1,250.0 mg/mL, 2,500.0 mg/mL and 2,500.0 mg/mL, respectively, for S. mutans, S. oralis, and S. salivarius); and minimum values with Thymol (312.5 μg/ml, 156.2 μg/mL and 156.2 μg/ml, respectively for S. mutans, S. oralis, and S. salivarius). All the tested phytochemicals displayed antibacterial activity, thus representing substances with potential applications in preventing tooth decay.

title: Exogenous niacin treatment increases NADPH oxidase in kiwifruit

description: Abstract Kiwifruit are a popular fruit worldwide; however, plant growth is threatened by abiotic stresses such as drought and high temperatures. Niacin treatment in plants has been shown to increase NADPH levels, thus enhancing abiotic stresses tolerance. Here, we evaluate the effect of niacin solution spray treatment on NADPH levels in the kiwifruit cultivars Hayward and Xuxiang. We found that spray treatment with niacin solution promoted NADPH and NADP+ levels and decreased both O2·- production and H2O2 contents in leaves during a short period. In fruit, NADPH contents increased during early development, but decreased later. However, no effect on NADP+ levels has been observed throughout fruit development. In summary, this report suggests that niacin may be used to increase NADPH oxidases, thus increasing stress-tolerance in kiwifruit during encounter of short-term stressful conditions.

title: La competencia estratégica y cultural en el aprendizaje de la entonación de (des)cortesía del español por parte de brasileños

description: ABSTRACT In this paper we apply the Communicative Competence model proposed by Cantero (2008) to teach the politeness intonation of Spanish for brazilians, focusing mainly on the development of strategic and cultural competences. Based on the review of the politeness and impoliteness intonation of Spanish and the prelingual intonation features of Spanish spoken by brazilians, we aim at offering some methodological examples in the teaching of the courteous intonation. The purpose is to develop strategic and cultural competences in order to prevent linguistic and cultural diversity from being a source of misunderstanding and incomprehension between Spaniards and Brazilian Spanish speakers while cultivating personal relationships.

title: Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study

description: ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) in the Triângulo Mineiro region, Brazil, describing the soil-water-landscape relationships to understand land use and water resources. To this end, we applied physical, chemical, micromorphological, and morphometric methods. When dry, compaction was observed in well-structured Ferralsols (Latossolos) with medium texture under intensive agriculture, reducing the water recharge capacity. The soil carbon stock was highest in hydromorphic savannas (veredas), reaching an organic matter content of 316.8 g kg-1 in the studied Umbric Gleysols, representing poorly drained lowlands. Physical and micromorphological properties were relevant parameters to understand the water recharge in soil; in agricultural fields, bulk density tended to increase and hydraulic conductivity to decrease, particularly under long-term sugarcane; morphometric parameters in the Frutal catchment indicated a low flooding risk and high flow capacity. This reinforces the need for soil conservation strategies to enhance water infiltration and groundwater recharge, with a view to maintain the water longer in the catchment. For surface water dynamics, slope morphology is an important property, affecting soil erosion, water retention and crop productivity.

title: Oral history and memories of Hansen’s disease patients in two Colombian leper colonies: life trajectories, conflicts and resistance strategies

description: Abstract: The paper examines the oral history of Hansen’s disease in two Colombian communities that were leper colonies until 1961. The oral history around the disease allows us to connect individuals’ memories with collective memory. This history remains an oral one, and few academic studies have documented it. We use oral history as a qualitative research method in order to analyze how the patients and those who lived alongside them positioned themselves in terms of the disease and how it permeated their entire existence, re-signifying the concepts of health and disease, normality and abnormality. We examine how, over the course of their lives, they engaged in resistance strategies that allowed them to get closer to normality, in their own sociocultural terms.

title: Presence of Cells in Fresh-Frozen Allogeneic Bone Grafts from Different Tissue Banks

description: Bone replacement materials have been widely used to reconstruct atrophic jawbones. Based on previous reports demonstrating the presence of viable cells in bone blocks even after processing by musculoskeletal tissue banks for orthopedic use, the aim of this study was to evaluate the presence of cells in bone blocks from three Brazilian tissue banks for maxillary reconstructions. All samples were processed by the respective tissue banks, according to the guidelines of the Brazilian National Sanitary Surveillance Agency. Three samples were removed from each block for subsequent histological processing and stained using hematoxylin & eosin. Further evaluation included section staining by the Feulgen method and ultrastructural analysis using scanning electron microscopy (SEM). Light microscopy images from all bone samples showed presence of osteocyte-like cells in all groups and intense Feulgen staining, demonstrating presence of DNA in bone even after tissue processing. The ultrastructural analysis showed red blood cells in lacunae within the bone tissue. In conclusion, despite bone tissue processing by the musculoskeletal tissue banks, cells may be found within the bone used for allogeneic grafts.
