title: SOFT-TISSUE INJURY TO THE FOOT AND ANKLE: LITERATURE REVIEW AND STAGED MANAGEMENT PROTOCOL

description: ABSTRACT Complex trauma of the foot and ankle is characterized by fractures with severe soft tissue damage associated with neurovascular injury and joint involvement. These injuries are frequently present in the polytraumatized patient and are a predictor of unfavorable clinical outcome. In the initial approach to a patient with complex foot and ankle trauma, the decision between amputation and reconstruction is crucial. The various existing classification systems are of limited effectiveness and should serve as tools to assist and support a clinical decision rather than as determinants of conduct. In the emergency department, one of two treatment options must be adopted: early complete treatment or staged treatment. The former consists of definitive fixation and immediate skin coverage, using either primary closure (suturing) or flaps, and is usually reserved for less complex cases. Staged treatment is divided into initial and definitive. The objectives in the first phase are: prevention of the progression of ischemia, necrosis and infection. The principles of definitive treatment are: proximal-to-distal bone reconstruction, anatomic foot alignment, fusions in severe cartilage lesions or gross instabilities, stable internal fixation and adequate skin coverage.

title: Therapeutic evaluation of magnetic hyperthermia using Fe3O4-aminosilane-coated iron oxide nanoparticles in glioblastoma animal model

description: ABSTRACT Objective: To evaluate the potential of magnetic hyperthermia using aminosilane-coated superparamagnetic iron oxide nanoparticles in glioblastoma tumor model. Methods: The aminosilane-coated superparamagnetic iron oxide nanoparticles were analyzed as to their stability in aqueous medium and their heating potential through specific absorption rate, when submitted to magnetic hyperthermia with different frequencies and intensities of alternating magnetic field. In magnetic hyperthermia in vitro assays, the C6 cells cultured and transduced with luciferase were analyzed by bioluminescence in the absence/presence of alternating magnetic field, and also with and without aminosilane-coated superparamagnetic iron oxide nanoparticles. In the in vivo study, the measurement of bioluminescence was performed 21 days after glioblastoma induction with C6 cells in rats. After 24 hours, the aminosilane-coated superparamagnetic iron oxide nanoparticles were implanted in animals, and magnetic hyperthermia was performed for 40 minutes, using the best conditions of frequency and intensity of alternating magnetic field tested in the in vitro study (the highest specific absorption rate value) and verified the difference of bioluminescence before and after magnetic hyperthermia. Results: The aminosilane-coated superparamagnetic iron oxide nanoparticles were stable, and their heating capacity increased along with higher frequency and intensity of alternating magnetic field. The magnetic hyperthermia application with 874kHz and 200 Gauss of alternating magnetic field determined the best value of specific absorption rate (194.917W/g). When these magnetic hyperthermia parameters were used in in vitro and in vivo analysis, resulted in cell death of 52.0% and 32.8%, respectively, detected by bioluminescence. Conclusion: The magnetic hyperthermia was promissing for the therapeutical process of glioblastoma tumors in animal model, using aminosilane-coated superparamagnetic iron oxide nanoparticles, which presented high specific absorption rate.

title: Climatic indicators and soybean yield in Rio Grande do Sul

description: Abstract The main of this work was to identify teleconnection patterns that influence soybean yield variability in Rio Grande do Sul in order to find potential predictors of agricultural yield in the State. Soybean yield data from 87 municipalities provided by the Brazilian Institute of Geography and Statistics were used. These series were grouped into three homogeneous groups of yield by cluster analysis. Lag correlations between climatic indexes associated with teleconnection patterns and mean soybean yield of each of the three groups evidenced the importance of each index for the crop in Rio Grande do Sul. Among the teleconnection patterns, the ones that presented most significant correlations, confidence higher than 90%, and persistent with soybean yield were the Arctic Oscillation (negative between October and December), North Atlantic Oscillation (negative between October and January) and Sea Surface Temperature anomalies in the Atlantic Ocean, between 20°S-30°S and 20°O-40°W, (positive between December and March). These indices also showed a high correlation with the precipitation between December and March for each homogeneous group evidencing the importance of their monitoring for the planning of the soybean farming in Rio Grande do Sul.

title: The Development of Multiplicative Calculation Flexibility by 3rd Grade Students

description: Abstract This article aims to understand how the students develop the multiplicative calculation flexibility in a context of exploratory teaching, answering three research questions: (i) What are the strategies used by students when solving multiplication tasks?; (ii) How do the strategies used by the students evolve?; and (iii) How do the students use the multiplicative calculation in a flexible manner? The investigation adopts a qualitative methodology within an interpretive paradigm having been held a teaching experience in a 3rd grade classroom. The data collection took place through the following techniques: participant observation and documentary collection. The article focuses only one pair of students. The results show that students used multiple strategies to solve tasks involving multiplication, evolving from additive strategies, associated with sequences of multiples, to multiplicative strategies, establishing numerical relationships, and using known basic multiplication facts and properties. This evolution is associated to the development of multiplicative calculation flexibility by the students, which is initially anchored in organizing the objects in equal parts, evidencing, at the end of the teaching experience, a clear connection between the idea of the same product being symbolized by a high number of multiplicative decompositions, the operation of division and the identification of the proportional relationship. The study shows the lack of parallelism between the development of multiplicative strategies in calculation and proportional situations.

title: Elaboration and sensory analysis of cookies made from avocado lump flour

description: Abstract A good alternative that has been developed and applied in recent years is the use of residues from the processing of fruits and vegetables. Much of what is discarded from raw materials such as peels, seeds and stems can be reused in the production of novel foods. The objective of this work was to develop and evaluate the acceptance of cookie elaborated from avocado lump flour. Three formulations were used in the cookie development: F1 (biscuit formulation added with 5% of avocado lump flour); F2 (biscuit formulation added with 10% of avocado lump flour); and F3 (biscuit formulation added with 20% of avocado lump flour). After elaboration, cookies were evaluated for physical-chemical characteristics (moisture, ashes, lipids, proteins, carbohydrates and caloric value) and sensorial characteristics (acceptability of appearance, color, texture and taste attributes, besides purchase intention). Among the formulations tested, F1 (biscuit formulation added with 5% of avocado lump flour) was well accepted by the tasters, since it presented the highest scores on the sensorial attributes evaluated and an above-average purchase intention (70%). Thus, this study demonstrated the importance of the integral use of residues from the processing of plant originated products in new products development, with potential for commercialization and a higher nutritional value.

title: EVALUATION OF DISTAL FOREARM FRACTURES USING THE AO 2018 CLASSIFICATION

description: ABSTRACT Objective: Distal forearm fractures are among the most common upper limb fractures in all ages, and many classifications have been proposed to describe them. Recently, a new version of AO/OTA classification was proposed. The aim of this study is to use the AO/OTA 2018 classification to report the epidemiology of distal forearm fractures in adults treated at a single center. Methods: A retrospective analysis of the initial radiographs obtained from cases of distal forearm fractures in an orthopedic emergency room at a single tertiary hospital. Results: Three hundred twenty-two cases were studied, aged 50.35 ± 18.98 years, 55.3% were female and 44.7% were right-sided. Type 2R3A, 2R3B and 2R3C fractures corresponded to 32.3%, 18.0% and 48.4% of the cases, respectively. Distal ulnar fracture was present in 41.9%. There was a correlation between age and sex: 78.3% of the subjects aged under 30 years were male, and 80.6% of those aged over 60 years were female (p&lt;0.001). Conclusion: The most common type of radial fractures was 2R3C, and the most common type of ulna fracture was 2U3A1.1. There was a correlation between age and sex. Level of evidence IV, Case-series.

title: Commercialization of food in school canteens

description: Abstract The purpose of this study was to evaluate the commercialization of food in commercial canteens located in the school environment of different educational networks, types of administration and presence of technical professional (nutritionist). The observational study was carried out in 111 canteens, of which 35 were private schools and 76 were public schools in Curitiba, Paraná, Brazil. To carry out these evaluations, a checklist containing a set of pipelines based on the state legislations of Paraná was prepared. According to current legislation, it was found that 97.37% of the canteens in public institutions and 94.29% of the private ones marketed foods considered banned because of their low nutritional value. The main prohibited foods marketed in the canteens were the industrialized snacks, the chocolates, the bullets and the artificial juices. These were also the best-selling foods and beverages, according to those responsible. In addition, 73.87% of the canteens did not have technical supervision, 89.19% did not provide two types of fruit and only 1.80% had an educational wall, as required by current legislation. It is concluded that canteens, regardless of the teaching network and type of administration, are in disagreement with the current legislation, both in the marketing of prohibited foods and in the absence of two types of fruit and in the absence of education mural. The results showed that frequent supervision of the technician is necessary to contribute to the choices of commercialized food and, consequently, to improve the nutritional quality of products offered for sale.

title: Potential of hydrogen (pH) differentially modulates cadmium stress response in abscisic acid-deficient sitiens tomato mutant

description: ABSTRACT Uptake of nutrients and cadmium (Cd) are dependent upon many factors, including plant species, ions concentration and pH. Tolerance to Cd-induced oxidative stress can be modulated by phytohormones such as abscisic acid (ABA), which induce the production of reactive oxygen species, activating proteins and enzymes involved in stress response and possibly stress tolerance. The present study aimed to evaluate the biochemical variations induced by Cd in ABA-deficient sitiens tomato mutant (sit) and its wild-type counterpart, Micro-Tom (MT), grown at different pH conditions. The plants were cultivated in nutrient solution (pH 5, 6 and 7; 20-days) and were then further grown over a 48-h period in 0 or 50 ?M CdCl2 at pH 6. Before Cd addition, the concentrations of nitrogen, sulfur, copper, iron and zinc were determined and variations in nutrients concentrations were observed. After Cd addition, sit roots grown at pH 5 and 7 did not exhibit differences in ascorbate peroxidase (APX) activity in 0 or 50 ?M CdCl2, and sit root grown at pH 6 exhibited lower glutathione reductase (GR) activity in the presence of Cd. Moreover, sit shoot grown at pH 5 showed decreased activities of superoxide dismutase (SOD), Mn-SOD II and Cu/Zn-SOD V, in 0 and 50 ?M CdCl2. The results indicated that pH modulates the plant nutrition in a complex way and may involve multiple ABA signaling pathways. Likewise, ABA status seems to be related with the Cd-translocation within the plant, suggesting that Cd, ABA and pH responses cannot be evaluated as isolated systems.

title: The use of firewood for home consumption and the fabrication of hand-crafted ceramics in a semi-arid region of Northeast Brazil

description: ABSTRACT This study aimed to identify, analyze and compare different uses of firewood for home consumption and for handicraft work in rural communities in Altinho, Pernambuco, Brazil. Semi-structured and free-listing interviews were performed to catalog the plants that were better known by locals and that were mostly used as firewood for home consumption and handicraft work. Two in situ inventories were performed at the homes of the study location in order document the plants that were actually used. A total of 39 species of woody plants belonging to 16 botanical families were registered. The most widely-known species for both uses were also the species that were most used and preferably-used-as-wood by the population. The plants most preferably-used-as-wood by the participants, which were selected as samples, were also those that the participants identified as having superior quality. Thus, there is a small group of plants that is used for both activities, and thus more vulnerable to extractivism, and which ought to be conserved. Alternative management strategies are needed that secure the availability of these species in the future to meet the needs of the local population and to conserve biodiversity.

title: The Teaching of Irrational Numbers in Basic Education and in Mathematics Teacher Education: a vicious circle is underway?

description: Abstract This article presents a reflection about the lack of articulation between the teaching of irrational numbers in Basic Education and in the initial mathematics teacher education. In basic education, the subject is treated with superficiality and little conceptual deepening, basically by way of examples, while in the mathematics teacher initial formation, there is the prevalence of the formalist approach to irrational numbers, which does not enable the future teacher to teach the subject in basic education. Felix Klein had already pointed out the result of this break between undergraduate and basic education in mathematics over a century ago - there is a double discontinuity in teaching. In the case of irrational numbers, more specifically, this mismatch can provoke a vicious cycle: the teacher leaves the university without adequate formation to address the subject in Basic Education, causing the students to reach the university without an adequate image of the irrational number, and the cycle repeats itself.
