title: Influence of Apical Diameter on Filling Material Extrusion during Retreatment - A Micro-CT and CBCT evaluation

description: Abstract Aim: To investigate whether foraminal widening performed at primary treatment has an effect on the amount of apically extruded obturator material during retreatment and to evaluate the sensitivity of cone beam computed tomography (CBCT) in detecting extruded obturator material. Methods: Forty palatal roots of maxillary molars were selected based on micro-CT and divided into two groups (n=20): with foraminal widening (WE) and without foraminal widening (NE). To standardize the apical foramen, all specimens were instrumented to the foramen using the Protaper Next system, up to instrument X3. The WE group was instrumented to the foramen up to instrument X5, and the NE group was instrumented 1 mm lower. The canals were obturated 1 mm below the apical foramen with gutta-percha and AH Plus and stored for 7 days at 37 °C and 95% humidity. Roots were fixed in microtubes filled with 1.5% agar gel. The obturation material was removed with Reciproc R50. Scans of the teeth and agar were performed using micro-CT and CBCT. Comparison between groups and between methods was performed using Mann-Withney test (p ≤0.05). Results: No statistical difference was found when comparing the extruded material between groups using micro-CT (p = 0.589) or CBCT (p = 0.953). CBCT measured a greater volume of extruded material than micro- CT (p = 0.0004). Conclusion: Foraminal widening had no effect on the extrusion of filling material during retreatment. The CBCT favored the evaluation of apically extruded filling material.

title: Phytotechnical performance and resistance to leaf-footed bugs of green maize intercropped with Poaceae in the Amazon savannah

description: ABSTRACT Green maize has great economic value, and the consumer market increasingly demands the production of ears for fresh consumption that are free from damage by pest attacks. The aim of this study was to evaluate the performance of varieties of AG1051 green maize and Roraima maize (ethnovariety Milhão) intercropped with dwarf grain sorghum, forage sorghum and millet in an environment of the Amazon savannah. We evaluated phytotechnical characteristics of the maize and damage from the leaf-footed bug (Leptoglossus zonatus). The experiment was set up in a 2 x 4 factorial randomised block design with four replications, where the two maize varieties corresponded to the first factor and four intercropping systems to the second factor. Regarding vegetative and reproductive components, Milhão had a longer cycle, greater plant growth and smaller stem diameter than AG1051, causing plant lodging. The intercropping systems had no influence on the production or quality of maize ears for any of the cultivars under study. Milhão did not differ from the AG1051 hybrid in any ear quality variable (ear length, number of grains per ear, cob diameter, ear weight and total number of ears). The AG1051 cultivar was preferred by L. zonatus, but had the highest yield of commercial ears. The intercropping systems had no influence on the damage caused by the leaf-footed bug.

title: Hemochromatosis-like disease in Brazilian tapirs (Tapirus terrestris) in Pará state, Brazil

description: ABSTRACT We report two cases of hemochromatosis-like disease in captive Brazilian tapirs, Tapirus terrestris in Pará state, Brazil. Both animals presented symptoms of chronic hepatopathy associated with marked accumulation of hemosiderin. The coloration of Perls demonstrated pronounced iron accumulation in macrophages in the portal space, Kupffer cells, and, to a lesser extent, in the hepatocytes of the periportal region. Marked portal fibrosis was evidenced by Masson’s trichrome. The pathological mechanisms of this disease in tapirs are not yet well established. It has been suggested that the species may have different mechanisms of iron absorption and elimination, rendering them sensitive to elevation in dietary levels of this metal. Two previous reports of this disease in T. terrestris exist from zoos in Australia and Scotland. This is the first report of this disease in tapirs in Brazil based on histopathological and histochemical findings.

title: STAYS AND BREAKS IN THE TRAJECTORY OF TWO INTELLECTUALS IN THEIR CULTURAL PRACTICES OF MEDIATION IN PARANÁ (1850-1920)

description: Abstract The aim of this article is to examine the theme of female education from the study of the trajectory of two intellectuals: Iria Corrêa and Mariana Coelho, analyzing their cultural practices of mediation in Paraná, in the period between the second half of the 19th century and the first decades of the 20th century. Although the two have lived in different temporalities, they played the role of mediating intellectuals, configuring in their trajectories cultural practices that were characterized by offering artistic and educational options for women in their working contexts. The documentary corpus of this work is composed of sources from the periodical press of Paraná, Reports of the Public Inspectorate of Paraná (1906-1917) and the memories of Antonio Vieira dos Santos (1952). Methodologically, the option of this article is to work with the perspective of mediating intellectuals (SIRINELLI), the concept of trajectory (BOURDIEU) and gender (SCOTT).

title: REMEDIATION FROM PRINT TO DIGITAL NARRATIVES: A PROPOSAL FOR AN ACTIVE METHODOLOGY USING SCRATCH

description: ABSTRACT: This study was motivated by a concern with the recurring reports of teachers and professors who work in High School and Higher Education about the deficiency of students regarding natural language written in the standard norm and the organization of solutions to problems related to employing strategies associated with computational thinking (CT). Given this challenging context, we conducted an Integrative Literature Review to analyze didactic sequences of works involving the construction of multimodal narratives in Elementary School, which simultaneously work on developing written language and CT. In addition, classroom teachers were also interviewed to listen to their experiences regarding the investigated theme. Four volunteers participated in these exploratory interviews. As a result of the Integrative Literature Review and the interviews, we proposed a didactic sequence that includes remediation as the axis around which natural language written in the standard norm is articulated with the authorship of digital narratives to strengthen the student as a writer and the conscious use of linguistic varieties and to develop computational thinking. For future research, it is important to apply the proposed didactic sequence in a classroom context for its validation and improvement.

title: Landscape-innovation-policy: counter-hegemonic practices at the Cícero Guedes Camp (MST)

description: Abstract Since colonization in Brazil, populations resistant to its agrarian model have fought for the right to land, alternative agricultural production, and usufruct of the landscape. Such prerogatives indicate the possibility of hybrid landscapes in the rural sphere and show horizons that favor healthy production, non-exploitation of rural workers, and policies that contribute to resolving inequalities in the countryside. The struggle of the Landless Rural Workers Movement (MST) is discussed in this article, focusing on the landscapes they inhabit and on their ways of taking possession of such landscapes. Our reflection is based on the analysis of the Cícero Guedes (MST) camp, grounded on the Performance Assessment of the Built Environment, with readings from the innovation matrix in relation to the territory to see how it can affect the movement’s landscapes.

title: Three-dimensional assessment of internal adaptation measurement of three cad/cam ceramic systems

description: Abstract This study aimed to evaluate the internal adaptation of three different computer-aided design/computer-aided manufacturing (CAD/CAM) ceramic crowns. The internal adaptation of a polymer-infiltrated ceramic network material (Vita Enamic [VE]) was compared to two machinable glass-ceramics; Zirconia-reinforced lithium silicate (Vita Suprinity [VS]) and a lithium disilicate glass-ceramic (IPS e.max. CAD). Thirty human premolars of average size were prepared (n=10 each group) by computer numerical control to fulfill the criteria of all-ceramic crown design. Optical impressions were taken for each tooth preparation using the CAD/CAM scanner. Thirty crowns were fabricated using CAD/CAM system and divided into three groups (IPS e.max, VE, and VS). To assess the internal fit of tested crowns, the gap between the intaglio of each crown and the corresponding tooth surface was evaluated using a 3D digital scanner using the Triple-scan Protocol. One-way ANOVA followed by Tukey Post Hoc statistical tests were used to statistically analyze results of the internal fit. There was a statistically significant difference for all groups at the four axial walls (p = 0.000002). For total internal fit between groups, comparisons showed a statistically significant difference between all tested groups (p=0.000002). When each pair of groups was statistically compared with each other, all pair comparisons showed a statistically significant difference. IPS e.max CAD had the best internal fit, followed by Vita Enamic, then Vita Suprinity. For all ceramics tested, values of internal fit of all ceramics tested were within the clinically acceptable range.

title: Children with developmental language disorder: a frequency following response in the noise study

description: Abstract Introduction: Children with developmental language disorder have been reported to have poor temporal auditory processing. This study aimed to examine the frequency following response. Objective: This work aimed to investigate speech processing in quiet and in noise. Methods: Two groups of children were included in this work: the control group (15 children with normal language development) and the study group (25 children diagnosed with developmental language disorder). All children were submitted to intelligence scale, language assessment, full audiological evaluation, and frequency following response in quiet and noise (+5QNR and +10QNR). Results: Results showed no statically significant difference between both groups as regards IQor PTA. In the study group, the advanced analysis of frequency following response showed reduced F0 and F2 amplitudes. Results also showed that noise has an impact on both the transient and sustained components of the frequency following response in the same group. Conclusion: Children with developmental language disorder have difficulty in speech processing especially in the presence of background noise. Frequency following response is an efficient procedure that can be used to address speech processing problems in children with developmental language disorder.

title: Prevalence of cognitive impairment in Brazilian indigenous community from Amazonas

description: ABSTRACT. Studies on the prevalence of dementia in the indigenous population are still scarce worldwide. In the few available studies, prevalence evidence varies from low to very high, with early onset of the disease and high mortality rate after the initial diagnosis. Still, little is known about the rate of dementia in indigenous populations from low- and middle-income countries, where the dementia prevalence in the general population is estimated to increase significantly in the next decades. Objective: This study aimed to determine the prevalence of cognitive impairment and associated factors in Brazilian indigenous people of the Mura ethnicity in Amazonas, Brazil. Methods: A total of 217 indigenous individuals aged 50 years and older from Amazonas, Brazil, were submitted to cognitive assessment. Attention, memory, verbal fluency, visuospatial performance, and mood state composed the cognitive impairment diagnosis. Results: The prevalence of cognitive impairment was 43.3% (95%CI 36.6-49.7) and varied according to age [OR=1.03 (95%CI 1.00-1.06)], education [OR=0.74 (95%CI 0.62-0.87)], body mass index [OR=0.91 (95%CI 0.83-0.98)], and income [OR=0.52 (95%CI 0.27-0.99)]. Conclusions: Cognitive impairment had an early onset in an indigenous community, and its prevalence was greater in older individuals with low education and low family income. These findings highlight the importance of implementing public indigenous health policies focusing on health professional training for early cognitive impairment detection.
