title: Comparative effects of final canal irrigation with chitosan and EDTA

description: Abstract Chitosan is a natural, biocompatible chelating substance with potential for dental use. This study compared the effects of final canal irrigation with chitosan and EDTA on dentin microhardness, sealer dentin tubules penetration capacity, and push-out strength. Methodology: Fifty canine roots were distributed according to the final irrigation protocol (n=10): G1- 15% EDTA with conventional irrigation; G2- 15% EDTA with Endovac; G3- 0.2% chitosan with conventional irrigation; G4- 0.2% chitosan with Endovac; and G5- without irrigation. Specimens were obturated (AH Plus) and sectioned in 3 slices per root third. The first slice was used for microhardness and sealer penetration assessments under a laser confocal microscope. The second was utilized in a push-out strength test. The third slice was discarded. Data were analyzed using 2-way ANOVA and Tukey's post hoc test (α&lt;0.05). Failure mode was determined at x40 magnification. Results: Microhardness reduction was more significant in groups G2 and G4 (p&lt;0.05). Sealer penetration through dentin was significantly greater in group G2 (p&lt;0.05). There was no significant difference between groups G1, G3, and G4 (p&gt;0.05). In general, all experimental groups presented similar bond resistance (p&gt;0.05) that significantly differed from the control (p&lt;0.001). Mixed type failures were predominant. Conclusions: In general, 0.2% chitosan and 15% EDTA solutions act in a similar manner with regard to the variables studied. The use of Endovac potentiates the effect of these solutions.

title: Application of silver nanoparticles in food packages: a review

description: Abstract Silver nanoparticles (AgNPs) are antimicrobial agents that have a wide spectrum of action, including against pathogenic bacteria and spoilage fungi. However, their mechanism of action is not completely clarified. Nowadays, scientific interest on biological synthesis of AgNPs is growing, with emphasis in their extracellular biosynthesis by microbial cells, as it is the most reliable and ecologically correct method for production, yielding no toxic residues. AgNPs may be incorporated to biodegradable and non-biodegradable polymers for the production of food packages with antimicrobial properties, leading to greater safety and longer shelf life. However, it is important to carry out migration tests for new food packages incorporated with AgNPs, based on the effective levels for their inclusion in the packaging materials.

title: Influence of Modulated Photo-Activation on Shrinkage Stress and Degree of Conversion of Bulk-Fill Composites

description: Abstract This study aimed to evaluate the polymerization properties of bulk-fill materials (low and high-viscosity) by using high-intensity continuous light and intermittent photo-activation in terms of polymerization shrinkage stress and degree of conversion (DC). The following Bulk-fill and Conventional nanofilled resin composites were evaluated: Filtek Z350XT Flow (3M/ESPE), SureFil SDR Flow (Dentsply), Filtek Bulk Fill Flow (3M/ESPE), Filtek Z350XT (3M/ESPE) and Filtek Bulk Fill Posterior (3M/ESPE). A LED device (DB 685, Dabi Atlante) was used for both protocols: continuous uniform and intermittent photo-activation (light-on and light-off cycles) with identical radiant exposure (14 J/cm2). The polymerization shrinkage stress (n=6) was evaluated by inserting a single increment of 12 mm3 between two stainless steel plates (6×2 mm) adapted to a Universal Testing Machine (UTM), at different times. Measurements were recorded after photo-activation. The degree of conversion was evaluated by Fourier transformed infrared spectroscope (FTIR) with an attenuated total reflectance (ATR) accessory (n=5). Data were analyzed by three-way ANOVA and Tukey’s HSD (α=0.05) tests. Bulk Fill Posterior presented higher shrinkage stress values when photo-activated with the intermittent technique (p&lt;0.05). The intermittent photo-activation increased the degree of conversion for the low-viscosity bulk-fills (p&lt;0.05). Therefore, the use of modulated photo-activation (intermittent) must be indicated with caution since its use can influence the shrinkage stress and degree of conversion of composites, which varies according to the resin formulations.

title: Between sidewalks, graffiti and kinship: the city as a battlefield around lesbian/homoparentalities and access to the PMA in France

description: Abstract This paper seeks to investigate the relation between the access to reproductive technologies by same sex couples, especially lesbian women in France and different graffiti and interventions in urban France that are related to the topic of lebo/homoparental families and the access to the referred technologies. Specifically, it discuss the quarrel and disputes between graffiti pro and against the diversity of family configuration and the relation between these quarrels and the acceptance and legitimacy of these families in France. In conclusion, it shows that the disputes among the different graffiti end up calling attention not only to the correlation between city and family but also to the politic character of urban art and the procedural feature of kinship.

title: Tissue Response after Subcutaneous Implantation of Different Glass Ionomer-Based Cements

description: Abstract The aim of this study was to evaluate the subcutaneous connective tissue response of isogenic mice after implantation of different glass ionomer-based cements (EQUIA® Forte Fil, EQUIA® Fil and Ketac™ Universal Aplicap™). Eighty-seven isogenic BALB/c mice were allocated in 12 groups, 9 were considered as experimental groups (Ketac, E. Fil and E. Forte at 7, 21 and 63 days) and 3 controls (empty polyethylene tubes at 7, 21 and 63 days). After the experimental periods, the subcutaneous connective tissue surrounding the implanted material was removed and subjected to histotechnical processing and staining with hematoxylin and eosin. A histopathological description of the tissue reaction surrounding each material and a semi-quantitative analysis of collagen fiber formation and inflammatory infiltrate were performed. Additionally, the thickness of the granulomatous tissue in contact with each material was measured. Data were analyzed statistically (α=0.05) by the Kruskal-Wallis test, followed by Dunn post-test. Initially, the collagen fiber formation was not different among all the tested materials (p&gt;0.05) but was different at 21 days with the control group presenting the most advanced stage of collagen fiber formation. At 63 days, EQUIA® Forte Fil group showed the most advanced stage of collagen fiber formation, compared to EQUIA® Fil group (p&lt;0.05). The inflammatory infiltrate was not different among the tested materials in any experimental period (p&gt;0.05). The thickness of the granulomatous tissue was greater in the E. Forte group, compared to control in all periods. All glass ionomer-based cements showed tissue compatibility, according to the evaluated parameters.

title: One place, two epidemic moments: yellow fever (1896-1897) and influenza (1918-1919) outbreaks in Campinas, Sao Paulo

description: Abstract This study analyses mortality from yellow fever (1896-1897) and influenza (1918-1919) epidemics in the municipality of Campinas (SP, Brazil) during the period of the coffee-based economy, mass immigration and demographic and epidemiologic pre-transition –the end of the 19th century and the early decades of the 20th century. Such epidemics – transmitted by different agents – have occurred at distinct moments, seasonalities and pace, affecting the various population segments in different ways. They have disseminated through local population, mostly due to the great population mobility, facilitated by the expansion of the railway network in the State of São Paulo during that period, the sanitary and life conditions of the people affected, and the government’s actions. Consequently, they had implications in the dynamics and demographic evolution of the city and its public health policies. For this study, quantitative sources were used, especially Civil Records of Deaths of Campinas, Yearbooks of the Sanitary Services of the State of São Paulo, censuses and other qualitative sources from that period.

title: Homeopathy in the public health service: pre-assessment of activities in Recife, Pernambuco

description: Abstract This study is a pre-assessment of homeopathy activities in the municipality of Recife, Pernambuco. Review of official and technical documentation produced a preliminary logical theoretical model for this intervention, based on a matrix of criteria and indicators for evaluation. The model and matrix were submitted to key informants with expertise in the area, and the data were collected from six interviews in 2016. Three major components were seen to be needed for both tools: joint management and coordination; homeopathic care; and education, communication, and social mobilization. We expect the theoretical model and matrix of criteria and indicators which were developed and validated to serve as a reference to establish procedures for monitoring and assessing similar interventions.

title: Migration flows between levels of the Brazilian urban hierarchy in the period 1980-2010

description: Abstract In the 1980s, an inflexion was observed in the spatial redistribution of the Brazilian population, attributed to the relative economic decentralization initiated in the 1970s, especially regarding industrial activities. These changes in the national space economy led to dramatic changes in the volumes and directions of migration flows. This paper researches the impact of the changing patterns of migration across the Brazilian urban hierarchy over the last three decades to determine if a process of deconcentration, as pointed out by some authors, is, in fact, underway. The flows between different levels of the urban hierarchy were calculated based on census data and represented visually in a series of graphs. If a process of deconcentration is occurring, an increase of flows from urban centres positioned in the higher hierarchical levels to lower order centres is expected. This study indicates a process of population concentration in larger cities, but not in the highest level of the urban hierarchy - which suggests an inflexion of historical metropolization tendencies in Brazil. The growing importance of “Regional Capitals”, the second highest level, suggests a process of restructuration and relative decompression of the urban system, although the pace of these changes is slowing down.

title: INFORMATION TECHNOLOGY GOVERNANCE IN SMALL AND MEDIUM ENTERPRISES - A SYSTEMATIC MAPPING

description: Abstract Information Technology (IT) governance in small and medium-sized businesses is a subject that still requires more effort. Many of the studies that deal with this subject refer to large companies. IT governance structures, originally developed for the context of large enterprises such as COBIT, ISO/IEC 35800 or ITIL, when applied to the context of small and medium enterprises, lead to undesirable results and failures in the deployment process. The objective of this work was to perform a systematic mapping on IT governance in small and medium enterprises between 2007 and 2017. Systematic mapping studies are useful for categorizing and summarizing the existing information concerning a research question in an unbiased manner. Thus, from an initial set of 63 papers, a total of 17 research papers were selected for the mapping study. The results obtained allowed us to reach conclusions concerning the state-of-the-art of IT governance mechanisms, theories applied in the context and the consequences of IT governance. From the results of this study it was possible to perceive the low use of relational mechanisms of IT governance in the studied context, the constant need to adapt frameworks such as COBIT and ITIL, so that they can adapt to the reality of SMEs, the wide variety of theoretical approaches and the importance, for SMEs, of the concept of IT value for the business.

title: Association between sarcopenic obesity, muscle strength and risk of cardiovascular and cardiometabolic diseases in the elderly: A systematic review

description: ABSTRACT To describe the findings in the literature about the association between sarcopenic obesity, muscle strength and risk factors and/or cardiometabolic or cardiovascular diseases in the elderly. A research was carried out in the following databases: Medical Literature Analysis and Retrievel System Online, Web of Science, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Latin America and Caribbean Health Sciences Literature) and Capes Journals, using the following search terms in English, Spanish and Portuguese: “obesity sarcopenic” OR “sarcopenic obesity” in the title AND “cardiometabolic disease” OR “cardiovascular disease” OR “metabolic syndrome” OR “insulin resistance” in the title/abstract AND “aged” in all fields of search with the variation of the “muscle strength” descriptor in all fields of this research. Articles were selected according to the following exclusion criteria: studies evaluating only sarcopenia and the risk of cardiometabolic/cardiovascular disease in the elderly, studies evaluating only obesity and the risk of cardiometabolic/cardiovascular disease in the elderly, studies that did not present the used method, studies in animals and studies that were not in Portuguese, English or Spanish. The researchers of the present study found a heterogeneity of methods for the identification of sarcopenic obesity, and a transversal cohort was used in most of the studies. It was possible to verify the association of sarcopenic obesity with risk factors and/or cardiometabolic or cardiovascular disease. Sarcopenic obesity is associated with risk factors and/or cardiometabolic or cardiovascular disease in the elderly. Establishing a robust definition of sarcopenic obesity in the elderly is necessary for further clinical studies and interventions.
