title: Replacement of fluorescent lamps with light emitting diode (LED) in an educational institution: environmental, energetic and economic concern

description: ABSTRACT Fluorescent lamps (FLs) can cause serious environmental and human health problems. This is due to the presence of mercury in its constitution and that, when discarded improperly, they can cause soil, air and water contamination. Light emitting diode (LED) lamps, in addition to being more economic and with a life longer than fluorescent lamps’, they provide greater brightness and, when replaced, do not contaminate the environment. The objective of this study was to evaluate the substitution of FLs with LED at the Federal University of Uberlândia (UFU), in Uberlândia, Minas Gerais (Brazil), by analyzing their environmental impact and economic and financial viability. It was possible to conclude that LED lamps stand out in terms of maintainability, durability, energy efficiency, economy and lower environmental impacts, being up to twice as efficient as FLs and not generating toxic waste. In this scenario, the economic and financial viability for FL’s substitution in UFU was verified, since that if a sample of 1,000 FLs was considered, the projected economy was between 55.75 and 80.78% by the end of 13 years and the return of the amount spent at the end of the first year. However, what stood out most in this experiment was the importance of the replacement from the environmental point of view, since it primarily contemplates sustainability actions in an educational institution.

title: Brazilian Spotted Fever Prevention through a Nonlethal Capybara Population Control Strategy

description: Abstract INTRODUCTION: Brazilian spotted fever (BSF), a lethal tick-borne Rickettsioses (2000 - 2018 &gt;600 human deaths) involving synanthropic capybara as host. METHODS: We introduced an alternative to mitigate human-capybara conflicts and epidemiologic concerns of BSF. Complex aspects like transmission dynamics, risk areas, host mobility, and birth rate control, were considered to develop a prevention strategy using an anti-GnRH vaccine. RESULTS: The propositioned immunocontraceptive potentially remove and prevent the spread of BSF from endemic areas. CONCLUSIONS: We propose the anti-GnRH vaccine as a BSF prevention strategy based on these favorable results.

title: Associative design: topography analysis in the layout of roads and blocks

description: Abstract In land parceling design, a diversity of normative and user requirements that should be taken into account. Those include the relationships between topography, road system and cost. In this paper, the authors propose an associative model as a tool to visualise those relationships to support the decision-making process and the resolution of design problems. Following the Design Science Research Methodology, an artifact in the form of algorithms was created to make a visual representation of the topography of a lot and to allow real time feedback for the study of road layout proposals based on the assumption that urban infrastructure costs are mainly defined by the length of the roads. To apply and evaluate the artifact, a social housing project (SHP) was chosen as the object of study for which the parameters, variables and constraints were established, based on the information collected through a literature review. The study demonstrates the feasibility of associative systems as a decision-making aid to the SHP design process, especially in the initial stages of feasibility analysis and design conception.

title: PSYCHOSOCIAL CHARACTERISTICS IN CHILDREN WITH ASTHMA REGARDING PHYSICAL ACTIVITY

description: ABSTRACT Introduction Children who are more active enjoy sports, have confidence in their ability to engage in physical activity, feel competent and perceive fewer barriers to physical activity. Objective Psychosocially characterize the asthmatic child’s relationship with enjoyable physical activity, physical self-concept, health and perceived quality of life. Method Eighty asthmatic children (age = 11.33 ± 1.10 years, body mass index [BMI] = 20.52 ± 3.83 kg/m2) and 80 healthy children (age = 11.18 ± 1.00 years, BMI = 20.81 ± 4.24 kg/m2) participated in the study. The Physical Activity Enjoyment Scale (PACES), Physical Activity Questionnaire for Children (PAQ-C), the Physical Self-concept Questionnaire (CAF) and the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) were used. Results In the PACES questionnaire, healthy children had a better level of general physical activity while in the CAF questionnaire, significant differences were found in ability, physical fitness and general self-concept, which were higher in healthy children. There is a significant correlation between the PAQ-C and ability, general physical self-concept, PACES and total PAQLQ in asthmatic children. Conclusion Asthmatic children had lower levels of physical activity, physical self-concept and enjoyment in physical activity than healthy children. Level of evidence II; Retrospective study.

title: Thermal, physical and mechanical evaluation of concrete blocks with recycled expanded polystyrene

description: Abstract The research project produced concrete blocks with partial replacement of traditional coarse aggregate by recycled expanded polystyrene. Hence, an experimental dosage was proposed, associating the Compressible Packaging Model with Tango´s adapted methodology, published in 1994, to produce four types of blocks (one reference, without substitution, and three with content ratios of 5, 10 and 15% of partial volumetric replacement of coarse aggregate by expanded polystyrene), with a w/c ratio of 0,5. Tests were performed to check the physical and mechanical characteristics of the blocks, following NBR 12118:2013, demonstrating that the reference block and the one with 5% coarse aggregate partial replacement could be used for structural applications, while the blocks with 10 and 15% partial replacement did not meet the NBR 6136:2016 standard for minimum compressive strength. The analysis of the thermal performance of the blocks was done using the calculation procedures of NBR 15220-2:2005, verifying the limits established by NBR 15575-4:2013. The thermal comfort provided by the reference blocks and the blocks with 15% replacement in the masonry prototypes presented similar internal temperature results during the observed period. However, at times when the highest environment temperatures were recorded, the masonry with recycled polystyrene presented maximum delay and thermal inertia.

title: A randomized, prospective clinical study evaluating effectiveness of a bulk-fill composite resin, a conventional composite resin and a reinforced glass ionomer in Class II cavities: one-year results

description: Abstract Bulk-fill restorative materials such as bulk-fill composite resins and high viscous glass ionomer cements have become very popular materials in operative dentistry because their application is easy and time-saving. Objectives: The aim of this clinical study was to evaluate the clinical performance of a highly viscous reinforced glass ionomer material, a bulk-fill composite resin and a micro hybrid composite resin in Class II restorations. Methodology: In total, 109 Class II restorations were performed in 54 patients using three different restorative materials: Charisma Smart Composite (CSC); Filtek Bulk Fill Posterior Restorative (FBF); Equia Forte Fil (EF). Single Bond Universal adhesive (3M ESPE, Germany) was used with composite resin restorations. The restorations were evaluated using modified USPHS criteria in terms of retention, color match, marginal discoloration, anatomic form, contact point, marginal adaptation, secondary caries, postoperative sensitivity and surface texture. The data were analyzed using Chi-Square, Fischer's and McNemar's tests. Results: At the end of one year, 103 restorations were followed up. No changes were observed during the first 6 months. At the end of one year, there were small changes in composite restorations (FBF and CSC) but no statistically significant difference was observed between the clinical performances of these materials for all criteria (p&gt;0.05). However, there was a statistically significant difference between EF, FBF and CSC groups in all parameters except marginal discoloration, secondary caries and postoperative sensitivity in one-year evaluation (p&lt;0.05). Conclusion: Bulk-fill composite resins and conventional composite resins showed more successful clinical performance than highly viscous reinforced glass ionomers in Class II cavities.

title: Grassland vegetation sampling - a practical guide for sampling and data analysis

description: ABSTRACT Grassland and savanna ecosystems are the original vegetation types of more than 30% of the Brazilian territory, but conservation and training of future professionals has largely focused on forests. In fact, no standard protocols exist for sampling grassland vegetation for environmental planning or licensing. Neglecting non-forest ecosystems may have deleterious consequences for the maintenance of biodiversity and the provisioning of ecosystem services. Herein, we provide practical guidelines on how to conceive and develop ecological studies of grassland vegetation for scientific, monitoring or technical purposes. Using examples mostly from southern Brazil, we explain and discuss the various components of the research process, from the question to be investigated to defining and implementing the sampling design, performing data analyses and presenting the results. Our guidelines should prove useful for training technicians and researchers working on grassland ecosystems and other non-forest ecosystems in Brazil and surrounding regions.

title: DNA hypermethylation of Fgf16 and Tbx22 associated with cleft palate during palatal fusion

description: Abstract Objective: Cleft palate (CP) is a congenital birth defect caused by the failure of palatal fusion. Little is known about the potential role of DNA methylation in the pathogenesis of CP. This study aimed to explore the potential role of DNA methylation in the mechanism of CP. Methodology: We established an all-trans retinoic acid (ATRA)-induced CP model in C57BL/6J mice and used methylation-dependent restriction enzymes (MethylRAD, FspEI) combined with high-throughput sequencing (HiSeq X Ten) to compare genome-wide DNA methylation profiles of embryonic mouse palatal tissues, between embryos from ATRA-treated vs. untreated mice, at embryonic gestation day 14.5 (E14.5) (n=3 per group). To confirm differentially methylated levels of susceptible genes, real-time quantitative PCR (qPCR) was used to correlate expression of differentially methylated genes related to CP. Results: We identified 196 differentially methylated genes, including 17,298 differentially methylated CCGG sites between ATRA-treated vs. untreated embryonic mouse palatal tissues (P&lt;0.05, log2FC&gt;1). The CP-related genes Fgf16 (P=0.008, log2FC=1.13) and Tbx22 (P=0.011, log2FC=1.64,) were hypermethylated. Analysis of Fgf16 and Tbx22, using Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG), identified 3 GO terms and 1 KEGG pathway functionally related to palatal fusion. The qPCR showed that changes in expression level negatively correlated with methylation levels. Conclusions: Taken together, these results suggest that hypermethylation of Fgf16 and Tbx22 is associated with decreased gene expression, which might be responsible for developmental failure of palatal fusion, eventually resulting in the formation of CP.

title: Aquatic vascular plants of South Brazil: checklist and a comparative floristic approach

description: ABSTRACT Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist of aquatic vascular plants of South Brazil and establishes their floristic affinities with bordering South America phytogeographical domains. The checklist was based on 52 sources, including 35 floristic lists, 17 regional taxonomic studies, and information from an electronic database on wetlands of South Brazil. Floristic similarities with published checklists for neighbouring regions were assessed. A total of 780 species distributed in 277 genera and 85 families of vascular plants were reported for South Brazil. Families with higher species richness were Cyperaceae (128), Poaceae (102), Asteraceae (69), Plantaginaceae (21), Lentibulariaceae (20), and Onagraceae (20). The most represented genera were Eleocharis (41) and Cyperus (24). A cluster analysis revealed high similarity with Iberá (Argentinian Chaco), Pampa and Atlantic Forest, and low similarity with Pantanal, Caatinga and the Amazon Rainforest. The high number of aquatic plant families recorded relative to temperate and tropical climates suggests a zone of biogeographical overlap in Southern Brazil. The compiled data set reveals high biodiversity of wetlands of South Brazil, provides a baseline for future research, and highlights the need for regional conservation planning.

title: EFFECT OF 16 WEEKS OF RESISTANCE TRAINING ON STRENGTH ENDURANCE IN MEN AND WOMEN

description: ABSTRACT Introduction Although resistance training (RT) can provide numerous benefits for both men and women, morphological, neuromuscular, metabolic, physiological, and behavioral differences between sexes may influence the magnitude of training responses. Objective To analyze the impact of 16 weeks of progressive RT on strength endurance in untrained men and women. Methods Twenty-eight men and 31 women (18-30 years) underwent a supervised RT program that was divided into two 8-week stages, 3 times per week on nonconsecutive days. The RT program was composed of exercises for different body segments (trunk, upper and lower limbs) that were performed with three sets of 8-12 repetitions maximum (RM), in 10 and 12 exercises, in the first and second stage, respectively. Strength endurance was assessed in 3 exercises (bench press, squat, and arm curl) and in a combination of these exercises through a protocol composed of 4 sets performed to failure with 80% of 1-RM on the baseline, after 8 and 16 weeks of RT. Results Group vs. time interactions (p &lt;0.05) were found for bench press (men = +28.3% vs. women = +32.1%), squat (men = +13.5% vs. women = +32.7%), and arm curl (men = +20.2% vs. women = +24.4%) exercises, as well as in the set of all 3 exercises (men = +18.4% vs. women = +31.2%). Conclusion Our results suggest that 16 weeks of RT can improve strength endurance in both men and women, although higher gains are achieved by women. Level of evidence II; Therapeutic study-Investigating treatment results.
