title: 200.000 IU of vitamin D does not reduce resting Blood Pressure and Inhibit Post-Exercise Hypotension in elderly women: a pilot study

description: Abstract Given the scarcity of studies with elderly and the existence of studies investigating the effect of vitamin D supplementation in PEH (post exercise hypotension), this study evaluated the effect of a single megadose of vitamin D on resting blood pressure (RBP) and post-exercise hypotension (PEH) in the elderly. 11 hypertensive elderly women (70.3 ± 1.7 years) received a single megadose of 200.000 IU of cholecalciferol or a placebo, orally, through capsules. On day 7, the subjects performed 30 minutes of aerobic exercise with blood pressure measurement before exercise and every 10 minutes after exercise during 60 minutes, besides cardiac autonomic modulation. RBP did not significantly change. Exercise promoted significant systolic PEH only in one moment post exercise in treated group and in the placebo group promoted significant systolic PEH at four moments. Significant diastolic PEH did not occur in any of the groups. Sympathovagal activity increased at post exercise balance in supplemented subjects at 20 min, 40 min, 50 min and 60 min when compared to rest; this increase was not observed in the placebo. A megadose of vitamin D did not reduce RBP, promoted partial inhibition of systolic PEH and increased sympathovagal balance.

title: Progress Test in Medical School: a Systematic Review of the Literature

description: Abstract: Progress Test is an objective assessment, consisting of 60 to 150 multiple-choice questions, designed to promote an assessment of the cognitive skills expected at the end of undergraduate school. This test is applied to all students on the same day, so that it is possible to compare the results between grades and analyze the development of knowledge performance throughout the course. This study aimed to carry out a systematic and literary review about Progress Test in medical schools in Brazil and around the world, understanding the benefits of its implementation for the development of learning for the student, the teacher and the institution. The study was carried out from July 2018 to April 2019, which addressed articles published from January 2002 to March 2019. The keywords used were: “Progress Test in Medical Schools” and “Item Response Theory in Medicine” in the PubMed, Scielo, and Lilacs platforms. There was no language limitation in article selection, but the research was carried out in English. A total of 192,026 articles were identified, and after applying advanced search filters, 11 articles were included in the study. The Progress Test (PTMed) has been applied in medical schools, either alone or in groups of partner schools, since the late 1990s. The test results build the students’ performance curves, which allow us to identify weaknesses and strengths of the students in the several areas of knowledge related to the course. The Progress Test is not an exclusive instrument for assessing student performance, but it is also important as an assessment tool for academic management use and thus, it is crucial that institutions take an active role in the preparation and analysis of this assessment data. Assessments designed to test clinical competence in medical students need to be valid and reliable. For the evaluative method to be valid it is necessary that the subject be extensively reviewed and studied, aiming at improvements and adjustments in test performance.

title: Main causes of bird-window collisions: a review

description: Abstract Bird-window collisions are a major cause of bird mortality in the world; up to one billion birds die each year from collisions with glass panes in North America alone. However, relatively little attention had been given to this issue in the broad scientific literature, despite a recent increase in the number of papers. In this paper, the indexed literature on bird-window collisions was reviewed, specifically addressing the causal factors. The search retrieved 53 papers, mostly from North America. The factors linked to higher collision rates were large areas of continuous glass, the presence of nearby vegetation and feeders, bird migration, abundance, and behavior. Several factors were site-specific, preventing the global extrapolation of these findings. There is a lack of scientific knowledge regarding bird-window collisions in tropical countries. One of the challenges to mitigating this problem is the small amount of information and – frequently - the extrapolation of findings described for temperate regions to other areas. There is a need for a greater and urgent effort to fill this gap.

title: IQA FAL - Fuzzy water quality index for lotic environments

description: ABSTRACT The dissemination of information on water quality for a non-specialist audience is essential to support political and institutional actions for the management of aquatic environments. Therefore, water quality indices have been proposed since they are able to synthesize into a single value or category information, usually described from an extensive set of water quality variables. This research proposes a new water quality index, based on fuzzy logic, aimed at lotic environments, developed through the collaboration of experts in water quality of the Rio de Janeiro Environmental Agency (Instituto Estadual do Ambiente - INEA). The proposed index was applied to water quality data from the Paraíba do Sul River, obtained by INEA, in the years 2002 to 2009. The results of IQAFAL showed that the index was able to synthesize the water quality of this stretch of the Paraíba do Sul, satisfactorily matching the assessments of the water quality assessments contained in the reports available. It was also noticed that with this methodology it was possible to avoid the attenuation of the influence of a variable in critical condition was attenuated by the influence of other variables in favorable conditions, producing an inaccurate result in the final index.

title: Biotransformation of grape pomace from Vitis labrusca by Peniophora albobadia LPSC # 285 (Basidiomycota)

description: Abstract Grape pomace from Vitis labrusca is an important sub-product of the “American table wine” industry. It is recalcitrant to degradation, and its accumulation is a serious problem with negative environmental impacts. We analyzed the ability of five white-rot fungi to transform this residue in-vitro. Mass loss and phenol removal in grape pomace treated with each fungus were compared after 30-day solid-state fermentation. Since Peniophora albobadia isolate LPSC 285 was the fungus that showed the highest degradative ability and the lowest free phenol levels in the residue transformed, we selected this fungus to monitor its effect on this residue after 30, 60, and 90 days of incubation. We analyzed mass loss of the residue caused by the fungus activity and its chemical changes using Fourier transform infrared spectroscopy. After 90 days of incubation, Peniophora albobadia isolate LPSC 285 reduced grape pomace mass by 20.48%, which was associated with degradation of polysaccharides and aromatic structures. We concluded that Peniophora albobadia LPSC # 285 isolate is a promising fungus to transform grape pomace from Vitis labrusca under solid-state fermentation conditions.

title: Genetic diversity and structuring in the arapaima (Osteoglossiformes, Osteoglossidae) population reveal differences between the Amazon and the Tocantins-Araguaia basins

description: Abstract Arapaima is a widely-distributed fish of enormous economic importance in the Amazon region. In the present study, a total of 232 specimens were sampled, 121 from five sites in the Amazon basin and 111 from five sites in the Tocantins-Araguaia basin. The analyses investigated fragments of the Cytochrome b, Control Region, Cytochrome Oxidase I, NADH dehydrogenase subunit 2 and seven loci microsatellites. The analyses revealed the existence of two mitochondrial lineages within the general area, with no haplotypes shared between basins, and genetic variability significantly higher in the Amazon than in the Tocantins-Araguaia basin. Two divergent, but sympatric mitochondrial lineages were found in the Amazon basin, but only a single lineage in the Tocantins-Araguaia basin. The existence of these two mitochondrial lineages indicates that past events, probably occurring during the Pleistocene, resulted in the separation of the populations of this species and molded its evolutionary history, which is reflected directly in its mitochondrial DNA. The analysis of the arapaima population structure identified distinct levels of diversity within the distribution of the species, indicating specific geographic regions that will require special attention for the development of conservation and management strategies.

title: Genome-wide analysis of the transcriptional response to drought stress in root and leaf of common bean

description: Abstract Genes related to the response to drought stress in leaf and root tissue of drought-susceptible (DS) and tolerant (DT) genotypes were characterized by RNA-Seq. In total, 54,750 transcripts, representative of 28,590 genes, were identified; of these, 1,648 were of high-fidelity (merge of 12 libraries) and described for the first time in the Andean germplasm. From the 1,239 differentially expressed genes (DEGs), 458 were identified in DT, with a predominance of genes in categories of oxidative stress, response to stimulus and kinase activity. Most genes related to oxidation-reduction terms in roots were early triggered in DT (T75) compared to DS (T150) suggestive of a mechanism of tolerance by reducing the damage from ROS. Among the KEGG enriched by DEGs up-regulated in DT leaves, two related to the formation of Sulfur-containing compounds, which are known for their involvement in tolerance to abiotic stresses, were common to all treatments. Through qPCR, 88.64% of the DEGs were validated. A total of 151,283 variants were identified and functional effects estimated for 85,780. The raw data files were submitted to the NCBI database. A transcriptome map revealed new genes and isoforms under drought. These results supports a better understanding of the drought tolerance mechanisms in beans.

title: Transport of dissolved material on impermeable surface under artificial rainfall analyzed with the application of face-centered experimental design

description: ABSTRACT The study of surface runoff and transport of pollutants is of major importance, as it helps preventing environmental impacts, and supports planning tasks carried out by public authorities. The goal of this research was to study the dynamics of the transport of material (NaCl) on an impermeable surface, dissolved by the application of water through a rainfall simulator, having as its source of variation three independent variables: slope, rainfall intensity and position of the material. Face-centered experimental design was used, which contemplated different scenarios reproduced in the experiments, where the influence of the three independent variables on the dependent variables (transport time, peak value, peak time and total mass transported) was evaluated, whose responses were monitored at the outlet of the experimental model. The analysis of the results allowed to identify the significant effect of the slope and position of the material on all the dependent variables studied, as well as the quadratic effect of the slope for the transportation time and total mass transported. As for the rainfall intensity, only influence was observed for transportation time, within the study intervals with a level of significance of 95%. The resulting model is capable of explaining: 90% for transport time, 67.9% for peak value, 74.2% for peak time and 62.4% total mass transported.

title: Spatial dynamics of orange production in the state of Paraná, Brazil

description: Abstract The aim of this study was to identify and qualify the microregions specialized in orange production and the spatial dynamics of citrus production in the state of Paraná, Brazil. For this purpose, data from the Brazilian Institute of Geography and Statistics and the Brazilian Central Bank were used. The location quotient (LQ) methodology was applied, the principal component analysis (PCA) and the cluster analysis were carried out, and information regarding the location of industries and agribusiness cooperatives that process orange juice in the state of Paraná was collected. The LQ results, subdivided into 5-year periods, denote changes in the spatial dynamics of orange production. Between 1998-2002 and 2013-2017, the specialized microregions increased from nine to 11; in addition, the consolidation of a citrus belt, which extended from the northwestern to the northeast area of Paraná, took place. Two main components explained 89.16% of the total data variability and four clusters were identified. The microregion of Paranavaí was the most specialized and the most important for the orange production chain in Paraná. The dynamics of orange production were spatially associated with the location of industries and agribusiness cooperatives in the sector, which were concentrated in the northwestern and mid-northern Paraná.

title: Evaluation of the Cardiac Effects of a Water-Soluble Lectin (Wsmol) from Moringa Oleifera Seeds

description: Abstract Background Moringa oleifera seeds, which are used for water clarification, contain a lectin named WSMoL which has shown in vitro antibacterial and immunomodulatory activity. Due to their nutritional value and therapeutic potential, the leaves and seeds of this tree are eaten in some communities. Some plant lectins are non-toxic to mammals, but others have been reported to be harmful when ingested or administered by other means. Objective As one of the steps needed to define the safety of WSMoL, we evaluated possible cardiotoxic effects of this purified protein. Methods: WSMoL was administered for 21 consecutive days to mice by gavage. Electrophysiological, mechanical, and metabolic cardiac functions were investigated by in vivo and ex vivo electrocardiographic recordings, nuclear magnetic resonance, and high-resolution respirometry. Results The treatment with WSMoL did not induce changes in blood glucose levels or body weight in comparison with control group. Moreover, the heart weight/body weight and heart weight/tibia length ratios were similar in both groups. Lectin ingestion also did not modify glucose tolerance or insulin resistance. No alterations were observed in electrocardiographic parameters or cardiac action potential duration. The heart of mice from the control and WSMoL groups showed preserved left ventricular function. Furthermore, WSMoL did not induce changes in mitochondrial function (in all cases, p &gt; 0.05). Conclusions The administration of WSMoL demonstrated a cardiac safety profile. These results contribute to the safety evaluation of using M. oleifera seeds to treat water, since this lectin is present in the preparation employed by some populations to this end.
