title: Assessment of validation and antioxidant activities of novel 12 Korean strawberry cultivars

description: Abstract In this study, antioxidant activities of extracts of 12 Korean strawberry cultivars were evaluated and validation of an analytical method for ellagic acid, a marker compound, was carried out. Cultivar 'Josaenghongshim' had the highest total polyphenol and flavonoid contents. In addition, cultivar 'Josaenghongshim' had the highest value and cultivar 'Seolhyang' showing the highest activity. Ellagic acid contents of 'Suhong', 'Okme', and 'Dahong' cultivars were the highest ellagic acid content. Correlation coefficient of the calibration curve was 0.9999, showing very high linearity. The HPLC-DAD method for the quantitation of ellagic acid content showed high linearity at various concentration ranges, with a limit of detection of 2.35 μg/mL. The limit of quantification was 7.13 μg/mL. Relative standard deviations from intra- and inter-day precision were less than 5.13%. Recovery rates of ellagic acid at 10, 50, and 100 μg/mL, respectively, were 99.0-100.1% with RSD values less than 5.30%. These results provide viable information for the validation of antioxidant capacities of 12 cultivars of Korean strawberries.

title: Photosynthetic material remobilization and its contribution to barley yield

description: Abstract The objective of this work was to evaluate the effect of seed rate, genetics, and environmental conditions on the remobilization of stored material from vegetative organs, as well as the contribution of this material to barley (Hordeum vulgare) grain yield. The experiment was carried out in a factorial randomized complete block design with four replicates, in the city of Gonbad Kavous, Iran, in 2016–2017 and 2017–2018 crop seasons. Two factors were evaluated: four seed rates (200, 300, 400, and 500 seed per square meters) and four barley genotypes ('Fardan', 'Khorram', 'Mahoor', and 'Sahra'). Material remobilization with an increasing seed rate per square meter contributed to barley grain yield, especially in the first year, when rainfall was lower. The highest and lowest contribution of remobilization to barley grain yield are related to the penultimate leaf and the flag leaf, respectively. In both years, 'Khorram' and 'Mahoor' genotypes show the highest and the lowest rates for reduction in grain yield, respectively, due to the increased seed rate per square meter.

title: EMPLOYMENT CONTRACTS AND TEACHERS’ ILLNESSES: ANALYSIS OF LEAVES FROM THE TEACHERS OF THE PUBLIC EDUCATION SYSTEM OF MINAS GERAIS’ STATE

description: ABSTRACT: This article tackles the health leaves from the basic education Teachers of the Public Education System of the State of Minas Gerais according to their legal employment contracts (either permanent or temporary designation), between 2016 and 2018. It is a study case carried out by means of document and quantitative research (descriptive analysis of data), as well as interviews. Curiously, the conclusion is that temporary teachers take fewer leaves than permanent teachers. However, their leaves are substantially longer. A fast analysis of this fact could deduce that, contrary to the early hypothesis of the study, the effective teachers fall ill more than the designated teachers. However, in this article, it is argued that this is, in fact, a strong indication that the designated teachers develop more severe illnesses than the effective teachers. In terms, this collaborates with the initial hypothesis of this study. The results indicate the development of illnesses in teachers performing their jobs and issue an important warning regarding the use of the temporary designation contracts, which was declared partially unconstitutional by the Supreme Court.

title: Within-Visit Blood Pressure Variability and Cardiovascular Risk in ELSA-Brasil Study Participants

description: Abstract Background Blood pressure variability (BPV) is of prognostic value for fatal and non-fatal cardiovascular outcomes. Objective This study aimed to evaluate the association between within-visit BPV and cardiovascular risk among participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods The present cross-sectional study was carried out using baseline data (2008-2010) of 14,357 ELSA-Brasil participants with no prior history of cardiovascular disease. Within-visit BPV was quantified by the coefficient of variation of three standardized systolic blood pressure (SBP) measurements using an oscillometer. Anthropometric measurements and laboratory tests were also performed. Cardiovascular risk was assessed using the atherosclerotic cardiovascular disease risk estimator (ASCVD) and multivariate logistic regression analysis was employed with a significance level of 5%. Results Significantly higher cardiovascular risk was determined by increased BPV for both sexes. A significantly higher prevalence of high risk was found in men than women across all quartiles, with the highest difference observed in the fourth quartile of variability (48.3% vs. 17.1%). Comparisons among quartiles in each sex revealed a significantly higher cardiovascular risk for men in the third (OR=1.20; 95%CI: 1.02 - 1.40) and fourth quartiles (OR=1.46; 95%CI: 1.25 -1.71), and for women in the fourth quartile (OR=1.27; 95%CI: 1.03 - 1.57). Conclusion Analysis of baseline data of the ELSA-Brasil participants revealed that blood pressure variability was associated with increased cardiovascular risk, especially in men.

title: Effects of phospholipid type and concentration on the emulsion stability and in vitro digestion behaviors of fish oil-loaded emulsions

description: Abstract Phospholipid (PL) have favorable emulsification ability. The simultaneous application of PL and protein is one of the research hotspots. In this work, the impact of egg yolk PL (EPL), soyabean PL (SPL) and their concentrations on the fish oil-loaded PL/gelatin (GTN)-stabilized emulsions were studied. The results suggested that SPL/GTN-stabilized emulsions comprised bimodal of droplets, and monomodal was observed in EPL/GTN, and GTN-stabilized emulsions. The related droplet sizes were as follows: 1.5% EPL/GTN &lt; 1.0% EPL/GTN &lt; 0.5% EPL/GTN &lt; 2.0% GTN &lt; 0.5% SPL/GTN &lt; 1.0% SPL/GTN &lt; 1.5% SPL/GTN.; and (4) Conclusion: The concentration of PL had significant effect on the droplet size and emulsion stability of the emulsions. The 1.0% SPL/GTN-stabilized emulsions demonstrated the optimal stability and droplet size when stored at room temperature for 15 days than emulsion contained PL. The addition of PL inhibited lipid oxidation and increased the rate of fatty acid release in vitro digestion. This work illustrated that PL/GTN-stabilized emulsions could potentially be a targeted delivery medium for nutrients or drugs.

title: Prevalence and impact of urinary symptoms on quality of life during the last month of pregnancy

description: Abstract Introduction Adaptations of the maternal organism can adversely affect the lower urinary tract, leading to urinary symptoms with impact in quality of life (QoL). Objective To determine the prevalence of urinary symptoms and the impact of urinary incontinence (UI) on QoL during the last month of pregnancy. Methods Retrospective cross-sectional study, envolving 96 women in the immediate postpartum period personally interviewed about urinary symptoms and QoL during their last four weeks of gestation. Women were divided into two groups according to the number of pregnancies: G1 = 1 pregnancy (n = 41) and G2 = ≥ 2 pregnancies (n = 55). Those who reported the presence of stress urinary incontinence (SUI) and/or urge incontinence (UUI) were also administered the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). Results The most common symptoms were nocturia (90.6%), urgency (82.3%), urinary frequency (71.9%) feeling of incomplete emptying (62.5%) and SUI and/or UUI (53.1%) with no differences between groups. Only the complaint of SUI in cough was significantly higher in G2 (p = 0.04). There was no difference on QoL between groups based on ICIQ-SF scores among those with UI (53.1%), however G1 reported serious impact and G2 very serious impact. Conclusion Almost all women reported some type of urinary symptom and the most prevalent were nocturia, urgency, pollakiuria, feeling of incomplete emptying and SUI and/or UUI. SUI was more prevalent among women with two or more pregnancies and during cough were significantly higher. Regardless of the number of pregnancies, the presence any type of UI had a negative impact on QoL.

title: Effect of surrounded shade and specimen`s thickness on color adjustment potential of a single-shade composite

description: Abstract This study evaluated the effect of surrounded shade and specimens` thickness on the color adjustment potential (CAP) of a single-shade composite. The composite Vittra APS Unique was surrounded (dual specimens) or not (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens of the control composite were also confectioned. Opacity and whiteness index for dentistry (WID) were calculated for simple specimens. Color differences between the simple (ΔE*SIMPLE)/ dual specimens (ΔE*DUAL) and the controls were calculated. CAP was calculated based on the ratio between ΔE* SIMPLE and ΔE* DUAL. The tested composite presented lower opacity (53 to 62% vs. 80 to 93%) and higher WID (≈ 42 vs. 18 to 32) than controls. Irrespective of the specimens’ thickness (1.0/ 1.5 mm), the lowest values of ΔE* SIMPLE (11.1/ 10.8) and ΔE*DUAL (7.2/ 6.1) were observed using the surrounding shade A1. The shade A3 yielded higher ΔE*SIMPLE (16.4/ 17.1) and ΔE* DUAL (11.3/ 12.3) than the A2 (ΔE*SIMPLE = 13.4/ 14.6; and ΔE* DUAL = 9.7/ 10.3). The specimen`s thickness significantly affected the CAP (0.35 and 0.44 for 1.0 and 1.5 mm, respectively) only for shade A1, which had the highest CAP values. The shade A3 resulted in higher CAP values (0.31) than A2 (0.27) when 1.0-mm thick specimens were used, but similar values were observed for 1.5 thick specimens (≈ 0.29). In conclusion, both surrounding shade and specimen thickness can affect the CAP of a single-shade resin composite.

title: Synergistic antiaging effects of jujube polysaccharide and flavonoid in D-Galactose-Induced aging mice

description: Abstract In this study, the synergistic effects of jujube polysaccharide (JP) and flavonoid (JF) on aging mice were investigated. Sub-acutely aging mouse models were established using D-galactose. Eighty experimental mice were randomly assigned to normal, model, vitamin C (200 mg/kg), JP (200 mg/kg), JF (200 mg/kg) and JP + JF (low (100 mg/kg), medium (200 mg/kg), and high-dose (300 mg/kg)) groups (10 mice in per group). After 35 days, the physiological aging indices of mice were measured. JP and JF displayed significantly positive synergistic antiaging effects. Compared with an aging model control group, groups administered JP and JF showed increased indices for the thymus and spleen and significantly increased activities of SOD and GSH-PX in the heart, liver, spleen, and brain (R2 &gt; 0.99, P &lt; 0.01; R2 &gt; 0.98, P &lt; 0.01). The contents of MDA in heart, liver, spleen, brain and serum were significantly decreased (R2 &gt; 0.95, P &lt; 0.01), while those of HYP in skin and serum were significantly increased. The concentrations of neurotransmitters (NE, DA, 5-HT, 5-HIAA) in the brain and serum of mice were significantly increased (P &lt; 0.01). These results indicated that JP and JF acted not only on relevant tissues or organs of mice, but on all body systems.

title: USING CONTENT ANALYSIS IN THE DEVELOPMENT OF AN EDUCATIONAL SOFTWARE: A CASE STUDY FOR TEACHING ABOUT ACADEMIC PLAGIARISM

description: ABSTRACT: The key to software development is to be able to grasp users’/customers’ needs. Thus, interaction with users/customers is extremely important. The objective of this work is, through a case study, to share the experience in the process of deriving the requirements of an educational tool/software using the technique of content analysis, bringing relevant information about the need, and the importance of the involvement of the user in the new products development process. To this end, we sought from the literature the best practices in the process of developing new products, detailing the importance of user/customer participation. Then, we conducted interviews with a group of potential users of the proposed educational tool, to clarify the following question: “What should an educational tool for teaching about plagiarism have to promote learning?” and, subsequently, the content analysis of the interviews. In this way, we could identify the most relevant contents in teaching about plagiarism to be treated by the tool and the pedagogical approaches, i.e., the didactic strategies used by teachers. The interviews were also essential sources to identify teachers’ needs and suggestions about the educational tool/software.
