title: Effect of gastric acid on the surface roughness and bacterial adhesion of bulk-fill composite resins

description: Abstract The purpose of this in vitro study was to evaluate the effect of gastric acid on the surface roughness and biofilm formation of bulk-fill composite resins. Twenty-seven samples of each composite resin were obtained: G1: Filtek Z250 XT (Z250), G2: Filtek Bulk Fill (FTK), G3: Tetric N-Ceram Bulk Fill (TTC), and G4: Aura Bulk Fill (AUR). The samples were quantitatively analyzed for surface roughness (Ra) using a roughness tester (n=15) and for biofilm formation (Cn) by the counting of colony-forming units (CFUs/mL) (n=9) in three different moments: after polishing (Ra0 and Cn0), after gastric acid immersion (Ra1 and Cn1), and after gastric acid and simulated tooth brushing (Ra2 and Cn2). Qualitative analysis through surface topography (n=3) was evaluated by scanning electron microscopy (SEM). Ra values were subjected to two-way repeated measures ANOVA, followed by Tukey’s test. Cn values were subjected to Kruskal-Wallis analysis, followed by multiple comparisons analysis (α=0.05). Z250 and FTK showed significant increases in surface roughness at Ra1. There were fewer CFUs/mL on TTC and AUR in relation to those of Z250 and FTK for Cn0, Cn1 and Cn2. The SEM images showed that gastric acid increased the formation of cracks, exposure of fillers and micro cavities for all composite resins. After tooth brushing, the topographical changes were more evident but did not influence biofilm formation. The gastric acid promoted both degradation of the surfaces and bacterial adhesion for all composite resins.

title: UNIVERSITY-COMPANY INTERACTION FOR TEACHING BASED ON REAL CASES IN ENGINEERING

description: ABSTRACT The content of the Quality Management subject in Production Engineering courses tends to commonly be developed without relating theory with practical activities. Considering this issue, our study investigates the university-company interaction in teaching and learning processes in an Engineering course in a manner that contributes both to the teaching activities at universities and practical activities at companies. Action research was developed from a project that partnered with a company from the automobile segment and a public university to bring real-life problems that are related to the curriculum of the quality management subject in a bachelor’s course in Production Engineering. Different resources and strategies were used: cases and training, which the company provided for in-classroom application; a final project that required student teamwork and constant contact with the company; and expository classes on the theoretical basis of Quality Management. Among the different results that were found, two factors were initially identified as barriers concerning the university-company logic, such as the execution time and the expected results of the project, and, in fact, they were facilitators of this dynamic. Another result was the increasing interest of students concerning the subject’s content as they demonstrated autonomy and responsibility during the process of knowledge creation at the course’s subject. We conclude, then, that the university-company interaction contributes to the creation of an environment that values that student as an active part that is inserted in a challenging scenario that, when enriched with constant feedback on the issues offered, promotes greater engagement and autonomy on students in regards to the learning process.

title: Expression of self-incompatibility in Coffea canephora genotypes grown in the western Amazon

description: Abstract The objective of this work was to characterize the expression of gametophytic self-incompatibility in a Coffea canephora breeding population, to assist in the management and development of new cultivars. For that purpose, 550 in vitro pollinations were carried out among 62 parent plants, of which 27 were from the conilon botanical variety and 35 from the robusta. Thirty-two genotypes compatible with all previously known testers were identified, suggesting the existence of new compatibility groups. From these results, hybridizations were carried out in a complete diallel design with reciprocal crosses to characterize new test plants. Based on the compatibility response with the test plants, the genotypes were clustered into the six following groups: group I, 11 (17.74%) genotypes; group II, 13 (20.97%); group III, 6 (9.68%); group IV, 9 (14.52%); group V, 8 (12.90%); and group VI, 15 (24.19%). The genotypes of the botanical variety robusta show a higher frequency of plants in compatibility group VI and a greater genetic variability, whereas those of the conilon variety have a higher frequency of plants in compatibility group II. The identification of new compatibility groups assists in new management practices that seek to increase the efficiency of pollination by favoring, through natural means, fully compatible crosses.

title: Serum high-mobility group box 1 protein level correlates with the lowest SaO2 in patients with sleep apnea: a preliminary study

description: Abstract Introduction: Serum level of high-mobility group box 1 protein is reportedly correlated with the severity of obstructive sleep apnea. Objective: We tried to evaluate the possibility of using the serum high-mobility group box 1 protein level as a biologic marker in obstructive sleep apnea patients. Methods: We generated a chronic intermittent hypoxia murine model that reflected human obstructive sleep apnea. Obstructive sleep apnea patients who underwent polysomnography were prospectively enrolled. Serum samples were obtained from mice and obstructive sleep apnea patients, and the serum high-mobility group box1 protein level was measured by enzyme-linked immunosorbent assay. Results: Serum high-mobility group box 1 protein level was 56.16 ± 30.33 ng/mL in chronic intermittent hypoxia and 18.63 ± 6.20 ng/mL in control mice (p&lt;0.05). The mean apnea-hypopnea index and respiratory disturbance index values of enrolled obstructive sleep apnea patients were 50.35 ± 27.96 and 51.56 ± 28.53, respectively, and the mean serum high-mobility group box 1 protein level was 30.13 ± 19.97 ng/mL. The apnea-hypopnea index and respiratory disturbance index were not significantly correlated with the serum high-mobility group box 1 protein level (p&gt;0.05). Instead, this protein level was significantly correlated with lowest arterial oxygen concentration (SaO2) (p&lt;0.05). Conclusion: High-mobility group box 1 protein may be involved in the pathogenesis of obstructive sleep apnea, and the possibility of this protein being a useful biologic marker in obstructive sleep apnea should be further evaluated.

title: Schooling of People with Cerebral Palsy: A Systematic Review in the National Literature

description: ABSTRACT: The inclusive perspective has broadened discussions about the education of the target audience of Special Education, related to the efectiveness of teaching, the use of resources, planning and pedagogical practices. Studies on cerebral palsy tend to focus on the clinical perspective, rehabilitation and care, distancing themselves from school activities. Thus, this study aimed to characterize productions about the schooling of students with cerebral palsy. For this, a systematic literature review was carried out in the Scientific Electronic Library Online (SciELO), in the Journal database of the Coordination for the Improvement of Higher Education Personnel (CAPES), and in the Revista Educação Especial [Special Education Journal], from 2000 to 2020. Thirty-one articles were selected according to the inclusion and exclusion criteria, categorized as Accessibility, Motor Development, Assistive Technology, Alternative Communication, School Inclusion, and Teaching. The results indicate that the national school context described in the studies is unprepared to meet the specificities of students with cerebral palsy, considering discussions on initial training and professional staf, physical and pedagogical resources ofered, which requires greater production of theoretical and practical knowledge in the country that responds to the guarantee of quality education to this student.

title: A Chip off the Old Block? Effects of Gender Homophily on Intergenerational Transmission of Entrepreneurial Behavior

description: ABSTRACT The intergenerational transmission is one of the key variables that shape entrepreneurship as an occupational choice. However, the role of gender is still a gap in the literature on intergenerational transmission of entrepreneurial behavior. Thus, this study aims to assess the effect of gender homophily in the intergenerational transmission of entrepreneurial behavior. The sample was composed of 10,889 students from the Federal Institute of Technology of Rio Grande do Norte. The probit regression method was applied to measure the probability of an individual becoming an entrepreneur if they are born of an entrepreneurial father or mother. The results show that being an offspring of an entrepreneurial father or entrepreneurial mother is associated with an increase in the probability of an individual becoming an entrepreneur. Moreover, the transmission is increased when the entrepreneurial parent and the offspring share the same gender.

title: Immunoexpression of proliferation and apoptosis markers in oral vascular anomalies

description: Abstract The biological behavior of lesions is highly dependent on the imbalance between their proliferative and apoptotic capacity. This study evaluated a correlation between the proliferative and apoptotic rates of different oral vascular anomalies (VAs) by analyzing the immunoexpression of proliferation (Ki-67) and apoptosis (Bcl-2 and Bax) markers in endothelial cells of 20 cases of GLUT-1 positive infantile hemangiomas (IHs), 20 cases of pyogenic granulomas (PGs) and 20 cases of vascular malformations (VMs). Immunoexpression analysis of Ki-67, Bcl-2 and Bax revealed a lower median percentage of positive cells in VMs cases compared to IHs and PGs cases (P &lt;0.001). The Wilcoxon signed‐rank test showed significantly higher percentages of immunostaining for Bax than for Bcl‐2 in IHs (P = 0.048). In the group of PGs, a positive correlation was observed between the immunoexpressions of Ki-67 and Bax (r = 0.476; P = 0.034). Although oral IHs, PGs and VMs present similar clinical and histopathological features, each of these lesions has its etiopathogenic particularities. The results of this study suggest that different biological behaviors of VAs may be related to differences in the proliferative and apoptotic profiles of their endothelial cells.
