title: How has dental pulp stem cells isolation been conducted? A scoping review

description: Abstract: The objective of this study was to realize a scoping review the literature in order to identify the profile of DPSCs isolation and analyze the possible risk factors that could change the native behavior of these cells. An initial search was conducted using the following MeSH terms: “(dental pulp stem cell [MeSH])”; “(dental pulp [MeSH])” AND “(stem cell [MeSH])”; “(“dental pulp stem cell” [MeSH]”)”. The electronic search was done without date restriction up to and including April 2014, in PubMed, Scopus, Scielo and ISI Web of Knowledge databases. Studies were submitted to inclusion and exclusion criteria and 222 articles were included. Data showed that over the past 15 years many studies have been conducted using DPSCs. However this is the first systematic review regarding the isolation of stem cell, and more specifically of dental pulp stem cells. The isolation of dental pulp stem cells showed great variability, hampering the development of standard protocols to achieve in vitro dental pulp stem cells with similar characteristics. This scoping review combined, for the first time, the methodologies used for dental pulp stem isolation, highlighting the most frequently used.

title: The Impact of the Resolution of Wind Fields on Predictive Wave Models

description: Abstract: In this paper the effects of the spatial and temporal resolutions of the wind field on the forecasting of wind waves are discussed. Three different meteorological events that generated waves in the Campos Basin (south-eastern Brazil) were simulated using the mesoscaleBrazilian Regional Atmospheric Modeling System(BRAMS) with high spatial resolutions of 20, 60, 100, 300 and 600 km and temporal resolutions of 1, 3 and 6 hours and the results were entered into WAVEWATCH (WW3). Two of these events were associated with the formation of extratropical cyclones in the South Atlantic which propagated with velocities above the local average and with large fetches. In the third event, the waves were associated with small fetches generated by the Subtropical South Atlantic Anticyclone (ASAS). The selection of these meteorological events, each with different physical characteristics, allowed us to evaluate the performance of the wave model as a function of the resolution of the wind field input. Our results indicate that the best spatial resolution in terms of computational cost versus error is 60 km,whereas the different time resolutions impose inconspicuous impact on the wave forecast.

title: Role-Play Preceded by Fieldwork in the Teaching of Pharmacology: from “Raw Sap” to “Elaborated Sap”

description: ABSTRACT Background: The task of teaching abilities, attitudes and knowledge, which can sometimes be complex, related to the safe and efficient use of medications, stands as a great challenge faced by medical schools nowadays. The role of the prescriber, therefore, who promotes the rational use of medication at undergraduate level gains importance in professional training, with a direct impact on public healthcare. In this context, the implementation of teaching methods that allow an active, critical and reflexive medical training for students is desirable in order to enable them to develop the skills required to manage the main pharmacological classes used by the general practitioner. We intend to describe and analyse role-play preceded by fieldwork as an educational strategy. Methods: Following the fieldwork regarding the utilization of the main pharmacological classes used in primary healthcare, 5-6 groups of students prepared scripts and staged role-plays involving practical aspects of pharmacokinetics, pharmacodynamics, side effects, and potential drug interactions regarding the main drug types. The intervention was assessed using students’ responses to questionnaires coupled with Likert scales, the Dundee Ready Education Environment Measure (DREMM) and semi-structured interviews. There was a correlation between participation in teaching practice and performance in multiple-choice questions in the final course evaluation. Results: All students felt involved and motivated in the activity. 78.5% strongly agreed and 19% partially agreed that the method allowed reflection on knowledge, abilities and attitude, all important to professional practice regarding rational therapeutic prescribing. The DREMM revealed a score of 129.23, consistent with a more positive learning environment in a reliable sample (Cronbach's alpha=0.86). Analysis of the open interviews allowed us to infer that the students considered the method efficient, dynamic, fun, and enjoyable, which enabled greater understanding and consolidation of the content. The strategy was considered stimulating regarding group activities, with active participation. Furthermore, it allowed students an opportunity to experience their future professional reality. The main weaknesses found were the unequal involvement of individuals in some groups and the great length of time spent in the preparation of activities. In the final exam, the students who participated in the intervention had, on average, a higher performance than those who did not take part in it. However, there was no statistically significant difference. Discussion: Role-play preceded by fieldwork proved to be a promising pedagogical strategy and may be used in other basic sciences.

title: ANALYSIS OF ISOSTATICALLY-BALANCED CORTICAL MODELS USING MODERN GLOBAL GEOPOTENTIAL MODELS

description: Abstract: The knowledge of the Earth's gravity field and its temporal variations is the main goal of the dedicated gravity field missions CHAMP, GRACE and GOCE. Since then, several global geopotential models (GGMs) have been released. This paper uses geoid heights derived from global geopotential models to analyze the cortical features of the Tandilia structure which is assumed to be in isostatic equilibrium. The geoid heights are suitably filtered so that the structure becomes apparent as a residual geoid height. Assuming that the geological structure is in isostatic equilibrium, the residual geoid height can be assimilated and compared to the isostatic geoid height generated from an isostatically compensated crust. The residual geoid height was obtained from the EGM2008 and the EIGEN-6C4 global geopotential models, respectively. The isostatic geoid was computed using the cortical parameters from the global crustal models GEMMA and CRUST 1.0 and from local parameters determined in the area under study. The obtained results make it clear that the isostatic geoid height might become appropriate to validate crustal models if the structures analyzed show evidence of being in isostatic equilibrium.

title: Effect of Ceramic Interposition and Post-activation Times on Knoop Hardness of Different Shades of Resin Cement

description: Abstract The aim of this study was to evaluate Knoop hardness of different shades of a resin cement light-cured directly or through ceramic discs, measured 15 min or 24 h after light exposure, and at different depths. Specimens of a commercial resin cement (Variolink Veneer) in seven shades, were fabricated in an elastomeric mold, covered with a mylar strip, a 0.7 mm thick ceramic disc (IPS e.max Press) was placed and the cement was light-activated for 20 s using a blue LED (Radii-Cal). The cured resin cement specimens were transversely wet-flattened to their middle portion and microhardness (Knoop) values were recorded at 15 min after light exposure and after deionized water storage at 37 ºC for 24 h. Five indentations were made in the cross-sectional area at 100 and 700 μm depths from the top surface. Ten specimens were made for each test conditions. Data were submitted to ANOVA split-plot design (shade, post-cure time, mode of activation and depth), followed by Tukey post hoc test (α=0.05). Significant differences for shade (p&lt;0.0001), mode of activation (p&lt;0.001), post-cure time (p&lt;0.0001) and depth (p&lt;0.0001) were detected. No significant interactions (p&gt;0.05) were found, except for shade x post-cure time (p&lt;0.0045) and mode of activation x post-cure time (p&lt;0.0003). Resin cement shade has a significant effect on Knoop hardness. Indirect activation through a ceramic material reduced significantly Knoop hardness. Hardness Knoop significantly increased after 24 h in all cements shades compared to values obtained after 15 min. Resin cement depth significantly reduced Knoop hardness.

title: Social participation in Primary Health Care towards the 2030 Agenda

description: Abstract Listening to society is an ethical reference to respond to its legitimate needs and aspirations. Considering as presuppositions the social participation and the right to the city, which are part of the 2030 Agenda, this study sought to recognize the voice of users that evaluated PHC services and their attributes. This descriptive and cross-sectional study used national ministerial evaluation data, outlining a region with 323 teams in 80 municipalities in the state of São Paulo and 1,272 users heard by authors. Users were mostly female, over 51 years old, with low income and schooling, eliciting challenges to population aging and selective care. Around 93% were 20 minutes away from health services and opening on Saturdays (43%) and at night (38%) would facilitate access. Some 60% were received without scheduling and 62% did not consider services prepared for urgent care. Some 85% received Community Health Workers and 40% other professionals, suggesting disparities in the incorporation of the territory to the care production process. In line with National Primary Health Care Policy and what is recommended by international conferences, social participation was recognized as a way to address the multiple aspects in the construction of universal health.

title: Association between disability and social capital among community-dwelling elderly

description: ABSTRACT: Objective: To assess the prevalence of disability and its association with social capital among community-dwelling elderly. Methods: The study was based on 2nd Health Survey of Belo Horizonte Metropolitan Region - 2010, that included 1,995 community-dwelling elderly, randomly sampled. The exposure of interest was social capital, measured by confidence in neighborhood, perception of the physical environment, sense of cohesion in housing, and neighborhood perception of help. Socio-demographic variables, health conditions and use of health services were considered in the analysis with the purpose of adjustment. Results: Approximately one third of participants (32.6%) were unable to at least one instrumental activity of daily living (IADL) and/or basic activity of daily living (ADL); the prevalence of disability in ADL/IADL was 18.1%, and only in IADL was 14.6%. Elderly with functional disabilities had higher odds of poor social capital, but only the sense of cohesion in housing neighborhood showed to be independently associated with functional disability (OR = 1.80; 95%CI 1.12 - 2.88). Conclusions: Our results show the importance of social capital in research on associated factors of functional disability and indicate the need to implement public policies for social and environmental areas, since the needs of the elderly require measures beyond those typical of the health sector.

title: A macroscopic classification of the embryonic development of the one-sided livebearer Jenynsia multidentata (Teleostei: Anablepidae)

description: ABSTRACT This study proposes eight stages according to the main discernible changes recorded throughout the embryonic development of Jenynsia multidentata. The development of morphological embryo structures, pigmentation, and changes in tissues connecting mother and embryo were included in the stage characterization. From the fertilized egg (Stage 1), an embryo reaches the intermediary stages when presenting yolk syncytial layer (Stage 2), initial pigmentation of the outer layers of the retina and dorsal region of the head (Stage 3), and the sprouting of the caudal (Stage 4), dorsal and anal fins (Stage 5). During the later stages, the ovarian folds enter the gills, and the body pigmentation becomes more intense (Stage 6), the body becomes elongated (Stage 7), and there is a greater intensity in body pigmentation and increased muscle mass (Stage 8). The dry weight of the batches varied between 0.6 ± 0.3 mg (Stage 3) to 54.6 ± 19.7 mg (Stage 8), but the dry weight of the maternal-embryonic connecting tissues remained almost constant. After controlling the effect of those reproductive tissues, the gain in dry weight of the batches throughout development increased exponentially from Stage 6, reflecting the increase in size and weight of the embryos due to matrotrophy.
