title: DIGITAL TECHNOLOGIES AS A PEDAGOGICAL RESOURCE FOR REMOTE TEACHING: IMPLICATIONS FOR CONTINUING EDUCATION AND TEACHING PRACTICES

description: ABSTRACT: This study emerged from inquietudes about the impasses that go through the experience of Emergency Remote Education (ERE) during the COVID-19 pandemic unleashed in 2020. In this sense, this article reports on a research whose objective was to analyze the implications of the use of digital technologies in the continuing education process and in the practices of literacy teachers, during the Remote Teaching, in 2020, in the Francisco Francelino de Moura Municipal School. The study was developed through a literature review of the main concepts that underpin the literacy process: pedagogical mediation, teaching practice and ERE. In addition, the normative documents of this type of teaching, the National Common Curricular Base, among others, were verified. We also conducted a qualitative field research with two literacy teachers of 1st and 2nd year (Literacy Cycle). The data treatment procedure used was Content Analysis. It was found that the teachers developed new practices, especially with the use of digital technologies and, despite the difficulties encountered, they sought to know and appropriate these resources resulting in a reflective practice of constant research and improvement.

title: Study of physiological maturity of melon seeds by enzymatic changes

description: ABSTRACT Plant species have different adaptation mechanisms regarding seed survival to desiccation, preventing cellular destruction during the water loss. The knowledge of these mechanisms is of great importance for the understanding of how the seed formation/maturation processes and the processes involved in germination occur. Thus, this study aimed to determine physiological and enzymatic changes during the maturation process of melon seeds of the cultivar BRS Anton, obtained from fruits at different maturation stages and subjected to post-harvest storage, by the action of total proteins and the enzymes catalase, peroxidase, and superoxide dismutase. Melon fruits were grown in a greenhouse at Embrapa Vegetables and harvested at five different times: 30, 45, 60, 75, and 90 days after anthesis (DAA). Thirty fruits were harvested in each season and 15 fruits had their seeds extracted immediately after harvest and the other 15 fruits were stored for 15 days. After processing and drying, the seeds were submitted to the following analyses: germination, first count, protein profile analysis, and activity of antioxidant enzymes (total proteins, peroxidase, catalase, and superoxide dismutase). The activity of the antioxidant enzymes from 60 DAA under storage showed a more orderly behavior, reaffirming the results of physiological tests. It shows that the seeds at this point of physiological maturation are well-formed and drying caused no damage to their cell membranes.

title: A SUMMARY ON FITRADEOFF METHOD WITH METHODOLOGICAL AND PRACTICAL DEVELOPMENTS AND FUTURE PERSPECTIVES

description: ABSTRACT This paper presents a broad overview of main contributions related to the FITradeoff (Flexible and Interactive Tradeoff) method. FITradeoff is a multicriteria method developed within the scope of the Multiattribute Value Theory (MAVT), considering partial information from the decision maker (DM) in the preference modelling process. Over the last few years, several methodological developments on this method have been published in the literature, as well as practical applications to a wide range of multicriteria decision problems. The most recent methodological advances are related to preference modelling process, which now integrate the two paradigms of elicitation by decomposition and holistic evaluation. Furthermore, contributions from behavioral studies, some of them including decision neuroscience, have enhanced the DSS free available for FITradeoff. In this paper, all previously developed works related to the FITradeoff method are approached, considering both methodological developments and practical applications. A summary on the different modeling approaches for solving different decision problematics (choice, ranking, sorting and portfolio) with FITradeoff is presented. The recently proposed combination of preference modeling paradigms - elicitation by decomposition and holistic evaluation - within the FITradeoff decision process is explained, as well its potential advantages for the elicitation process. Moreover, a brief review on the practical applications of the method in different contexts is presented. In addition, this work also brings a summary on the results of behavioral experiments conducted using neuroscience tools with the FITradeoff method, as well the methodological insights resulted from them, and future perspectives of potential research topics related to the FITradeoff method.

title: Effects of the juçara fruit (Euterpe edulis Martius) pulp and lyophilized extract on NRF2, KEAP1, SOD1, and GPX2 expression in human colorectal cancer cell lines

description: We investigated the effects of the juçara fruit (Euterpe edulis Martius) pulp and lyophilized extract on the expression of cytoprotective genes nuclear factor erythroid 2 (NF-E2)-related factor 2 (NRF2), kelch-like ECH-associated protein 1 (KEAP1), superoxide dismutase (SOD1), and glutathione peroxidase (GPX2) in human colorectal cancer cell lines (HT-29 and Caco-2). Cells were cultured for 24 h in Dulbecco's Modified Eagle's Medium containing juçara fruit pulp (5, 10, or 50 mg/mL) or lyophilized extract (0.05, 0.1, or 0.5 mg/mL), and gene expression was quantified using real-time quantitative reverse transcription polymerase chain reaction. All studied genes showed significant variation in gene expression among different concentrations of pulp or lyophilized extract. Overall, the expression of the selected genes decreased in both cell lines following exposure to the pulp or lyophilized extract in a dose-dependent manner for most of the concentrations studied. In summary, our study showed that the compounds in juçara fruit inhibited the expression of cytoprotective genes associated with the antioxidant response and that, although not cytotoxic at the concentrations studied, they could potentially block the activation of the NRF2/KEAP1 pathway.

title: Mannich bases derivatives of 2-Phenyl-5-Benzimidazole sulfonic acid; Synthesis, Characterization, Computational studies and Biological evaluation

description: Abstract A new series of N-Mannich bases of 2-Phenyl-5-benzimidazole sulfonic acid have been synthesized through amino methylation reaction with secondary amines. The two moieties were held together through a methylene bridge, which comes from formaldehyde (Formalin Solution 37%) used in the reaction. Chemical structures of the newly synthesized compounds have been confirmed using FT-IR, 1HNMR and 13CNMR. Different in vitro assays including Anti-oxidant, Enzyme inhibition, Anti-microbial and Cytotoxicity assay were performed to evaluate the biological potential with reference to the standard drug. Among the synthesized library, compound 3a shows maximum alpha-glucosidase inhibition with an IC50 value of 66.66 μg/ml, compound 3d was found most toxic with LC50 value of 10.17 μg/ml. ADME evaluation studies were performed with the help of Molinspiration online software. Docking calculations were also performed. Given the importance of the nucleus involved, the synthesized compound might find extensive medicinal applications as reported in the literature.

title: Birth weight and bone mineral density at 18–19 years: birth cohort 1997–1998

description: ABSTRACT OBJECTIVE To analyze the association between birth weight and bone mineral density (BMD) in adolescence. METHODS A birth cohort study in São Luís, Maranhão, using data from two moments: at birth and at 18–19 years. Exposure was the birth weight in grams, continuously analyzed. The outcome was BMD, using the Z-score index (whole body) measured by double X-ray densitometry (Dexa). A theoretical model was constructed in acyclic graphs to identify the minimum set of adjustment variables – household income, the mother knowing how to read and write at the time of birth, prenatal care, tobacco use during pregnancy, and parity — to evaluate the association between birth weight and bone mineral density in adolescence. Multiple linear regression was used in Stata 14.0 software. A 5% significance level was adopted. RESULTS From 2,112 adolescents, 8.2% had low birth weight and 2.8% had a low BMD for their age. The mean full-body Z-score was 0.19 (± 1.00). The highest birth weight was directly and linearly associated with BMD values in adolescence (Coef.: 0.10; 95%CI: 0.02–0.18), even after adjustment for the variables household income (Coef.: -0.33; 95%CI: -0.66–0.33) and the mother knowing how to read and write (Coef.: 0.23%; 95%CI: 0.03–0.43). CONCLUSION Although after adjusting the variables the association attenuated, birth weight positively and linearly relates to BMD in adolescence.

title: Cadmium exposure and Hypertensive Disorders of Pregnancy: a systematic review

description: ABSTRACT Hypertensive Disorders of Pregnancy (HDP) are one of the main causes of maternal morbimortality. Strong evidence point to an association between cadmium and hypertension in the general population, but not HDP. A systematic review was carried out to investigate this potential relationship, following PRISMA guidelines, in the BVS/LILACS, PubMed/MEDLINE, and SciELO databases and a repository (University of São Paulo – USP) until August 2021. The methodological quality was assessed using the Downs and Black checklist. Nineteen articles were selected, thirteen of which were case-control, four were cohorts, and two were cross-sectional. A total of 11.451 participants were evaluated, 1.445 (12.6%) with HDP, and of these 1.071 (74.1%) with preeclampsia. The inadequate adjustment for confounding was observed in eleven studies. Out of the seven studies considered good methodological quality, four reported a positive association, and three did not observe it. In contrast, only one observed a mean difference, which was higher in HDP. The inconsistency of the results was attributed to the methodological differences and inadequate adjustment for confounding. As cadmium is a toxic metal that can induce an increase in oxidative stress, which plays an essential role in the pathophysiology of HDP, additional studies are needed to elucidate this association.

title: Smartphone-based rapid and low-cost method for the determination of eugenol content of clove essential oil

description: ABSTRACT: The determination of eugenol in clove essential oil was performed using a smartphone-operated device, which was used for image capture and processing. The colorimetric reaction with the Folin-Ciocalteu reagent was used, and the lighting conditions were evaluated to capture images directly in 2 mL disposable vessels. The free application PhotoMetrix UVC was used for partial least squares regression calibration with suitable values (R² greater than 0.99). The accuracy of the proposed method was compared with traditional methods, such as gas chromatography (GC) and spectrophotometry, and it can be observed that there were no significant differences (Student’s t-test (P &gt; 0.05), with agreements from 97% to 101%. The smartphone method allowed the evaluation of several samples in a few minutes, with simple analysis steps and easy interpretation of the results. The miniaturized scale allowed the use of small amounts of reagents with minimal waste generation. Therefore, the proposed method can be easily operated in the field and allows the evaluation of the quality of clove essential oil in places of restricted access without the need for a laboratory structure and specialized analysts.
