Ação solvente do salicilato de metila sobre resilon e guta-percha

Objective: The aim of this study was to evaluate the action of methyl salicylate in dissolving Resilon and gutta-percha. Material and method: Ten discs of Resilon, Alpha gutta-percha and ProTaper gutta-percha were prepared (10 mm diameter × 1 mm thick) and kept at 37 °C for 48 hours. Each sample was weighed in a balance of accuracy determining the initial mass. The specimens were immersed in methyl salicylate or xylene (control) for 5  minutes, rinsed in water for 30 minutes, dried and subsequently weighed in 24 hours intervals until the stabilization of weight (final mass). The solvent capacity was expressed by the difference between the final and initial mass. The data were analyzed by using ANOVA and Tukey test with significance level of 5%. Result: The results showed that the methyl salicylate was more effective on Resilon than on gutta-percha (p < 0.05). Methyl salicylate and xylene had similar solvent action on Resilon (p > 0.05). The xylene showed better performance on gutta-percha than methyl salicylate (p < 0.05). Conclusion: It was concluded that methyl salicylate did not show solvent action on gutta-percha, however it showed effectiveness in dissolution of Resilon. Thus methyl salicylate can be a possible alternative to the use of xylene during endodontic retreatment of teeth obturated with Resilon.

Esse tal de brincar: um passeio sobre o espaço da brincadeira no desenvolvimento infantil : www.essetaldebrincar.com.br

This work consists in the creation of a multimedia product online, and is entitled Esse tal de brincar. The content is presented in the form of informative journalistic texts and brings the play as an essential process for child development, with an impact on adult life. Has the general objective to demonstrate the relevance of the importance of play in children's education. The methodology procedures of bibliographic search and documents for the construction of the theoretical basis were used. Besides the choice of themes, interviews, investigation and journalistic writing were used in production. The research that support the whole discussion is given through interviews, videos and other publications on childhood, education and the play itself. The platform chosen for this was the Wix® and were created the visual identity, such as layout, logo, color distribution, highlights, photos and videos. The publication seeks to achieve parents and educators with the intention of raising awareness about the importance of play in early childhood through informative content

Eu voltei para reimplantar a tua memória: para os que não ouviram

The oral records, deprived of great rhetoric elaboration, mark the family accounts and the testimonies about remarkable and apparently minor particularities of grand conflicts, like the World War II. The oral memory fulfilled an important function of historical transmission, especially in handing on to written record the organization of testimonies, revealing personal memories in the form of letters, diaries and narratives, besides of integrating itself to several works of fiction. In the present work we present the value of former partigiani’s testimonies collected in the volume Io sono l’ultimo (I am the last one) as evocation and transmission of personal remembrances strongly linked to the conflict and as manifestations in the literary field as well. The valuing by descendants and fellow countrymen of a tradition of memory communication make the testimony of men and women that fought for the liberation of many Italian locations much more than fragmented reports when the interested reader in the memory of those that survived, integrated to the micro-history of the events, perceive its expressive logic. We explore both the meaning of witness adopted by Giorgio Agamben and the esthetical value of the traumatized voice in the perspective of Márcio Seligman-Silva.

Bullfrog hemogram under management stress

Stress is one of the major obstacles in frog culture and can be caused by factors such as inappropriate farming systems; inadequate management among other situations. The objective of the present study was to assess the hemogram, erythrogram and leukogram of bullfrogs (L. catesbeianus) when exposed to stress caused by different types of management: density and handling (manipulation), developed in the laboratory and repeated in the field for the appropriate comparisons in a experimental period of 30 days. The density experiment was conducted with four treatments: 70 animals m(-2) (D70); 100 animals m(-2) (D100), Control; 150 animals m(-2) (D150) and 200 animals m(-2) (D200), with 10, 14, 21 and 28 animals/box in the laboratory, respectively. Each treatment was performed with three simultaneous replicates. The handling experiment was conducted with three treatments: Treatment Without Handling (WH); Treatment with Partial Handling (PH) every 15 days and Treatment with Total Handling (TH) every 15 days. Each treatment was performed with four simultaneous replications. The methodology of the blood analysis followed international recommendations. In the present study we could observe that the animals of the field experiment did not reflect the same stress response observed in the laboratory in both experiment, which demonstrated the plasticity of these animals.

Seleção de famílias e progênies de irmãos completos de cana-de-açúcar para atributos tecnológicos e de produção pelo método de REML/BLUP

The objective of this study was to assess families and highlight the superior progenies of sugarcane originating from 38 biparental crosses for the following attributes: tons of cane per hectare (TCH), tons of biomass per hectare (TBIOH), brix (% cane juice), fiber content, purity, pol and total recoverable sugar (TRS). The data were analyzed by mixed model REML / BLUP in the REML (Restricted Maximum Likelihood) allowed us to estimate genetic parameters and BLUP (best linear unbiased prediction) to predict the additive and genotypic values. The best family for the attributes TCH and TBIOH was 41, whose parents are cultivars IACSP022019 x CTC9. In individual selection for TCH, the plant number 3 of Block 2, the crossing 78, showed the best results. To TBIOH the plant number 33, Block 1, family 41, showed the best results. Families 40, 41, 43, 68, 69, 79, 91, 92 and 147, were higher for the variables brix, pol, purity, and ATR, where as 85 families, 147, 148, 149, 161, 163, 177, 178, 179, and 183 were higher for fiber. The family 147 whose parents are IACSP042286 x IACSP963055, showed three progenies ranked among the top ten for both brix, and for fiber, which identifies the combination as a potential source of progenies for bioenergy production.

Apuntes para un estudio comparativo entre torcidas organizadas e hinchadas

The present study proposes an initial approach to a comparative study between supporter groups from Brazil (torcidas organizadas) and Argentina (hinchadas). The text presents a thick description that points to similarities and differences, in synchronic and diachronic terms, between both groups of football spectators. The paper focuses on each group's emergence, organizational framings, logics of belonging, and most significant practices and representations. Finally, it illustrates the contributions of this research to the construction of a public sociology of regional sport.

Safety assessment of essential medicines for elderly people: a bibliographic survey

Certain medicines are considered potentially inappropriate (PIM) for elderly people as they increase the risk of adverse drug events (ADE) and because safer alternative therapies are available on the market. In this context, in order to identify the instruments that assess the quality of medical prescriptions for elderly and to determine which drugs are considered PIM, a bibliographic survey was conducted in PUBMED, LILACS and PAHO databases, in February and March/2010. The search strategy included the use of health descriptors and a manual search in the references cited by selected papers. During the period of data collection, 15 instruments were identified. In 2012, with the publication of the update of Beers criteria, this instrument was included in the study. We identified 163 PIM of 25 therapeutic classes, of which 125 (76.7%) are marketed in Brazil. Of these, 31 (24.8%) are essential medicines (RENAME 2012), of which 13 have safer therapeutic equivalents and 19 (15.2%) are over-the-counter drugs. Data suggest the need for inclusion of safer alternatives for the elderly in the national list of essential medicines and the pharmaceutical care for early detection of ADE in this age group, in order to contribute to the safe use of medicines.
