title: The anatomic analysis of the vidian canal and the surrounding structures concerning vidian neurectomy using computed tomography scans

description: Abstract Introduction: The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures. Objective: The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations between them which are crucial anatomical landmarks for preoperative planning. Methods: This study was performed using paranasal multidetector computed tomography images that were obtained with a section thickening of 0.625 mm of 250 adults. Results: The distributions of 500 vidian canal variants were categorized as follows; Type 1, within the sphenoid corpus (55.6%); Type 2, partially protruding into the sphenoid sinus (34.8%); Type 3, within the sphenoid sinus (9.6%). The pneumatization of the pterygoid process is mostly seen in vidian canal Type 2 (72.4%) and Type 3 (95.8%) (p &lt; 0.001). The mean distances from the vidian canal to the foramen rotundum and the palatovaginal canal were greater in the vidian canal Type 2 and 3 with the pterygoid process pneumatization (p &lt; 0.001). The prevalence of the intrasphenoid septum between the vidian canal and the vomerine crest and lateral attachment which ending on carotid prominence were much higher in vidian canal Type 3 than other types (p &lt; 0.001). The mean angle between the posterior end of the middle turbinate and the lateral margin of the anterior opening of the vidian canal was measured as 33.05 ± 7.71°. Conclusions: Preoperative radiologic analysis of the vidian canal and the surrounding structures will allow surgeons to choose an appropriate endoscopic approach to ensure predictable postoperative outcomes.

title: Phytochemical Profile of Pasture Weeds from the Brazilian Cerrado

description: ABSTRACT: The great diversity of plant species in pastures of the Brazilian Cerrado with distinct ecophysiological characteristics indicates the possibility of finding, in the cellular content of this flora, chemical compounds with potential for use in agriculture and human and animal health. Three steps are necessary to prove this hypothesis: phytochemical prospecting, characterization of secondary metabolites, and studies on the biological activities of these metabolites present in these plants. The chemical profile of secondary metabolites present in five species of the Brazilian Cerrado (Davilla elliptica, Remijia ferruginea, Luehea paniculata, Anacardium occidentale, and Acosmium dasycarpum) was traced in this research. These plant species were collected in pasture areas of Felício dos Santos, Minas Gerais. The samples were dried and submitted to two types of extract (ethanolic and hexanic). By using specific chemical reactions, the presence of coumarins, triterpenes/steroids, and anthracenosides was observed in the hexanic extracts, while the presence of alkaloids, triterpenes/steroids, flavonoids, tannins, reducing compounds, and anthocyanins was observed in the ethanolic extracts. The species presented diverse classes of compounds. However, triterpenes/steroids, tannins, reducing compounds and anthocyanins were found in all species, being the use of the solvent ethanol the most efficient in extracting the compounds. The species D. elliptica presented the highest number of classes of compounds. The widespread application in folk medicine justifies further studies on the biological activity of different metabolites in agriculture and health areas.

title: Leaching of Herbicides Commonly Applied to Sugarcane in Five Agricultural Soils

description: ABSTRACT: Leaching intensity depends on the physicochemical properties of soils and herbicides. Consequently, a good understanding of this process is essential to determine mitigation measures to reduce or eliminate the risk of water contamination around areas with sugarcane crops. Therefore, the objective of this study was to analyze the leaching of ametryn, diuron, hexazinone, and metribuzin by using columns in five soils with different physicochemical properties cultivated with sugarcane. The radiolabeled herbicides with 14C were evaluated at six soil depths (0-0.05, 0.05-0.10, 0.10-0.15, 0.15-0.20, 0.20-0.25, and 0.25-0.30 m) and in the leachate after 200 mm rainfall simulation for 48 h. Herbicide leaching was mostly affected by soil type. Ametryn and diuron were reported in the highest amount (&gt;87%) on the topsoil (0-0.05 m), which was indicative of the low leaching of these two herbicides in the soil profile. Thus, these herbicides can contaminate surface water by runoff. Leachate percentage was always &lt;0.3% for ametryn, diuron, and metribuzin; this was also the case for hexazinone in two out of the five soils. Hexazinone proved to be a potential contaminant of groundwater and metribuzin presented high leaching in the soil profile. Previous knowledge of the physico-chemical properties of soils cultivated with sugarcane is essential to recommend the use of these herbicides in weed management.

title: Perennial scientific distortions and their consequences to science teaching: the relationship among electricity, magnetism and heat

description: Abstract Historical distortions can promote a misunderstanding on science and to bring undesirable consequences to science teaching. In this work, we discuss a historical case study in which the description of a research was conveniently altered during their dissemination. As consequence, a distortion of concepts and procedures persists in history of science. This historical case is an example that to attribute facts, concepts and equations to a historical character implies more than a simple illustration.

title: Abiotic parameters and planktonic community of an earthen fish pond with continuous water flow

description: Abstract Aim Limnological conditions, phytoplankton and zooplankton communities in a fishpond highly affected by management during the dry and rainy seasons are investigated. Methods Water samples were analyzed for physicochemical parameters; soil samples were analyzed for macro- and micro-nutrients, phytoplankton and zooplankton communities, at four sites, during eight months in the rainy and dry seasons. Distance-based linear model (DISTLM) was applied with Akaike Information Criterion (AIC), where the influence of environmental variables in the variation of phytoplankton and zooplankton composition could be assessed and the best model could be selected. Results The multiparameter test revealed that variables pH, TSS and TP better explain the composition of the biotic community (AICc = 45.6; R2 = 0.80). Chlorophyceae was the dominant group with 32 taxa, or rather, 75-85% of total phytoplankton, with high density at 2,365-4,180 ind.L-1 during the sampling period. Rotifera was the most abundant group in the zooplankton community during the two seasons, except at IW2 during the dry season, when Copepoda had a higher density, namely, 52% of total zooplankton community at this site. Conclusions The contribution of allochthonous material to the fishpond during the two seasons mainly consists of macro- and micro-nutrients and thermotolerant coliforms that influenced the plankton community and enhanced high Cyanobacteria density in the rainy season. Plankton community in the studied pond was characteristic of small water bodies. Management protocol in places with continuous water flow according to the region may be an important tool to optimize and to avoid risks in fish production.

title: SOIL ATTRIBUTES AND INITIAL CORN DEVELOPMENT AS A FUNCTION OF FERTILIZATION AND INTERCROPPING SYSTEMS

description: ABSTRACT Fertilization systems that allow higher sowing speeds have been used in areas of grain production, as well as the use of intercropping to improve soil physical quality and provide better soil cover. This study aimed to evaluate soil attributes and the initial corn development and intercropping (corn + velvet bean, corn + pigeonpea, and corn + bonavist bean) as a function of fertilization systems (pre-sowing and sowing). The experiment was conducted in an Oxisol in a randomized block design in the 2 × 3 factorial scheme, with four replications. The number of days for emergence, plant stand, intercropping dry matter, soil straw cover, soil straw permanence index, penetration resistance, soil moisture, soil density, degree of compaction, and total soil porosity were measured. The percentage of soil straw cover was affected by fertilization system, mainly by pre-sowing fertilization. Soil physical attributes were not affected by fertilization and intercropping systems, except total porosity, in the 0–0.10 m layer, which has a combined effect of factors. The initial corn development was not affected by fertilization and intercropping systems. Velvet bean presented the highest number of days for the emergence and lower dry matter.

title: The effect of planting density on ‘BRS Rubimel’ peach trained as a “Y-shaped” system

description: Abstract The densification of orchards has become a viable alternative for producers seeking a greater use of current area, as well as greater profitability. In this sense, the spacing and training system to be used in the peach tree planting are extremely important to facilitate orchard management and, above all, to maximize tree yield. Based on this, the present research aimed to evaluate the possibility of orchard densification and the use of different numbers of main scaffolds to recommend the best way of training and spacing the ‘BRS Rubimel’ peach cultivar. The planting was carried out in 2010, in the city of Fraiburgo - SC, and eight treatments with different spacings between the plants in the rows and number of scaffolds were evaluated during four harvests (2013, 2014, 2015 and 2016): T1- 2 scaffolds and 0.75 m; T2- 2 scaffolds and 1.00 m; T3- 2 scaffolds and 1.25 m; T4- 2 scaffolds and 1.50 m; T5- 4 scaffolds and 1.00 m; T6- 4 scaffolds and 1.50 m; T7- 4 scaffolds and 1.75 m; T8- 4 scaffolds and 2.00 m, totaling a plant density of 2667, 2000, 1600, 1333, 2000, 1333, 1143 and 1000 per hectare, respectively. The analyzed variables were the number of fruits per plant, production per plant (kg); productivity (t ha-1); fresh fruit mass (g), total soluble solids content (ºBrix), total acidity (meq L-1), epidermal coloring and pulp firmness (pounds). The highest yields were found in the treatment with two scaffolds and 0.75m between plants, as well as that with 4 scaffolds in 1.0 m spacing in the 2014 and 2015 crops and two scaffolds in 1.0m in the 2015 harvest. The fresh mass, soluble solids, total acidity and fruit firmness were not influenced by the different treatments. It was concluded that the densification of orchards is feasible for peach trees of the ‘BRS Rubimel’ cultivar due to the increase in productivity, without decreasing the quality of the fruits, indicating a spacing of 0.75 cm between plants and two scaffolds in the “Y-shape” as ideal. Another option with good results is the use of the four-scaffold “Y-shaped” training system, indicated for the ‘BRS Rubimel’ peach trees, due to the maintenance of high yields and reduction in the number of plants per hectare when compared to treatments with two scaffolds.

title: Low-fat Brazilian cooked sausage-Paio – with added oat fiber and inulin as a fat substitute: effect on the technological properties and sensory acceptance

description: Abstract The aim of this study was to optimize the addition of oat fiber and inulin as fat substitutes in cooked Paio sausage using response surface methodology. The chemical composition, textural parameters, color properties, lipid oxidation, microbial analysis and sensory properties were assessed in twelve different treatments. The addition of dietary fiber led to a significant (P &lt; 0.05) increase in moisture content and also a decrease in fat content of between 60.78% and 63.16%. Color parameters were significantly affected by the addition of inulin and oat fiber, as lightness decreases with the addition of oat fiber. Similar happened with redness, the lowest results were for the treatment with higher dietary fiber content added. Regarding lipid oxidation, the inclusion of fiber did not influence the TBARS values among treatments and throughout the storage time. Sausages manufactured with inulin and oat fiber present similar scores for color, taste and overall acceptability, while lower texture values were found in sausages manufactured with oat fiber. The addition of up to 6% of inulin with up to 0.85% oat fiber in a low fat cooked Paio sausage did not compromise technological parameters and sensory acceptably.

title: Aquisição de Produtos da Agricultura Familiar em Municípios Paranaenses: análise dos produtos comercializados e dos preços praticados

description: Abstract: This study verified the adequacy of the article 14 of Law 11.947/2009, the types of products marketed and prices paid for vegetables for school feeding to family farmers in Paraná state. The types of products and respective prices were collected on the website of the National Fund for Education Development. In order to compare prices, we used data from the Food Supply Center of Curitiba (Paraná). As results, we obtained that more than half of municipalities (51%) still do not comply with the law, the other 49% reached 30% or more. Groups of fruits and vegetables demanded more resources. The prices paid are mostly higher than those practiced at Ceasa, and may suggest the practice of a value that allows taking into account expenses with logistics and other charges. However, there are still several products with lower prices, some of them marketed quite frequently, suggesting possible losses to the farmers with these foods. It is important to emphasize the importance of this market for rural development and, for this reason, the prices paid to family farmers must be attractive and fair, without harming the rationalization of public spending. Reaching this balance is a challenge to the executing entities, but paramount to the success of this policy.

title: Arterial stiffness in hyperthyroid patients is deteriorated due to thyroid hormones

description: ABSTRACT Objective The aim of this study is to evaluate and compare arterial stiffness, which is an independent risk indicator for cardiovascular diseases (CVDs), between patients with overt hyperthyroidism, subclinical hyperthyroidism, euthyroidism by antithyroid therapy and healthy volunteers with pulse wave analysis (PWA). Subjects and methods A total of 102 volunteers were included in the study (30 in the overt hyperthyroid group, 28 in the subclinical hyperthyroid group and 14 with euthyroidism by antithyroid therapy and 30 healthy). The arterial stiffness measurements of the participants in the study were performed with the Mobil-O-Graph PWA device (I.E.M. GmBH, Stolberg, Germany), which makes cuff based oscillometric measurement from the brachial artery. Results Systolic blood pressure, pulse rate, central systolic blood pressure, cardiac output, heart rate-corrected augmentation index (Aix@75) and pulse wave velocity (PWV) measurements were significantly higher in the hyperthyroid group than in the control group. The heart rate and PWV in the subclinical hyperthyroid group were significantly higher than the control group. In the euthyroid group, systolic blood pressure, central systolic blood pressure, cardiac output, cardiac index and PWV were found significantly higher than the control group. There was also a negative correlation between Aix@75 and thyroid-stimulating hormone (TSH), and a positive correlation between Aix@75 and free thyroid hormones. Conclusion In our study, we observed that the arterial stiffness was adversely affected by an overt or subclinical increase in thyroid hormones and this correlated with thyroid hormone levels. We recommend that PWV measurement, which is a simple method for detecting CVD risk, can be used in these patients.
