title: Growth and nutrient accumulation in the aerial part of red Pitaya (Hylocereus sp.)

description: Abstract Knowledge on the amounts of nutrients accumulated by pitaya in its different development stages allows defining the periods in which the essential elements are most required, thus contributing to the elaboration of rational fertilization programs for the crop, reducing production costs. This study aimed to evaluate the growth and nutritional requirement of red pitaya, estimating the accumulation of macro and micronutrients by the plants and determining the periods in which the greatest accumulations occur, as well as the relative growth rate and the relative nutrient absorption rate. Pitaya seedlings were planted in pots containing Argissolo Vermelho-Amarelo Eutrófico (Ultisol) and grown in the open air. The experimental design was randomized blocks, with four replicates and seven sampling times: 0, 60, 120, 180, 240, 300 and 360 DAP (days after planting). At each sampling time, length of cladodes, dry matter of the aerial part and nutrient accumulation in the aerial part were evaluated. Red pitaya plants showed a low growth rate until 60 days and, from this period, its growth increased significantly. Nutrient accumulation occurred in the following descending order: K &gt; Ca &gt; N &gt; Mg = P &gt; S &gt; Na element &gt; Zn &gt; Mn &gt; Fe &gt; B &gt; Cu. K and Zn were, respectively, the most exported macro and micronutrient by pitaya fruits.

title: Microstructural Analysis of AgIn5VI8 (VI: S, Se, Te) Ternary Semiconductors by X-Ray Diffraction

description: This work is a study of the microstructural properties of the polycrystalline ternary compounds AgIn5S8, AgIn5Se8, and AgIn5Te8 by X-ray diffraction technique (XRD). The full-width-half-maximum (FWHM) of the XRD profile is measured as function of the diffraction angle and used to estimate the microstructural parameters. In general, a microstructural characterization by XRD is principally performed by Strain/Size analysis based on the modified Scherrer formula, which in turn, allows for mean grain size and average microstrain to be computed. However, when applied to polycrystalline bulk semiconductors, the modified Scherrer formula gives grain sizes of the order of a few hundreds of nanometers, which is not usually observed in bulk materials. Instead, a new theoretical scheme with misfit dislocations and plastic deformations would be used to calculate the grain size into a bulk. Assuming that these dislocations are of elastic origin, we were able to calculate the misfit dislocations density as function of the elastic constants of the materials. With this, the modified Scherrer formula is corrected to explain the additional XRD line broadening. All microstructure parameters of our samples increase as the atomic radius of the VI-element increases, with elastic constants similar to related semiconducting compounds.

title: GAIT DISORDERS IN PATIENTS WITH INSTRUMENTED NEUROMUSCULAR SCOLIOSIS

description: ABSTRACT Introduction: The effect of spinal fusion on gait in patients with neuromuscular scoliosis continues to be a controversial issue, especially in patients where the spinal fusion extends to the pelvis. Objective: To evaluate the effect of spinal instrumentation in these patients. Methods: We evaluated 34 patients in a retrospective study. The mean age at surgery was 14±3 years and only ambulatory patients who presented neuromuscular scoliosis and non-progressing neurogenic pathology were included. The patients were surgically treated by posterior spinal fusion with or without extension to the pelvis. Preoperative (PRE) and postoperative (POP) Rx were measured. Ambulatory potential was clinically examined in all the patients, and 10 patients were assessed by full-gait analysis. Results: The minimum POP follow-up was 2 years (2006-2016). Nine patients were instrumented to the pelvis when the obliquity was greater than 15°; the remaining patients were treated using the same fusion-level criteria as those applied for idiopathic scoliosis. All patients maintained their gait, with improvements in coronal and sagittal balance, transfers and sitting skills, physical appearance, and in some cases, gait speed. Conclusions: Spinal instrumentation in ambulatory patients with neuromuscular scoliosis, including procedures with extension to the pelvis, provides adequate correction and preserves ambulatory function. Level of evidence III; Retrospective case control study.

title: Spatial distribution of triatomine bugs in a Chagas disease endemic region in Brazil

description: Abstract INTRODUCTION: Trypanosoma cruzi is the etiological agent of Chagas disease (CD), a zoonotic infection transmitted by triatomine bug vectors to human beings. Although the story of this parasitic infection was born in Brazil and here this has made major step forward information, the same cannot be said about the actual distribution of the triatomine vector in several areas of this country. The aim of this study was to assess the occurrence of triatomine species in an endemic region for CD in Northeastern Brazil. METHODS: A retrospective study was performed using data obtained from 2008 to 2017. All information was provided by the V Gerência Regional de Saúde of the state of Pernambuco. The spatial distribution of triatomine species was analyzed by drawing a map using the Quantum geographic information system. RESULTS: A total of 4,694 triatomine specimens (469.4 ± 221.2 per year) were collected during the period 2008-2017, with 94.5% (4,434/4,694) at the intradomicile and 5.5% (260/4,694) at peridomicile environment. Of all arthropods collected, 92.5% (4,340/4,694) and 7.5% (354/4,694) were adults and nymphs, respectively. The species most frequently detected were Panstrongylus lutzi (30.36%), Triatoma brasiliensis (26.12%), Triatoma pseudomaculata (22.43%), and Panstrongylus megistus (20.54%). CONCLUSIONS: These data contribute to a better understanding of the distribution of T. cruzi infection in the Northeastern region of Brazil. Preventive measures based on vector control should be implemented in the study area in order to reduce the burden this neglected tropical disease.

title: Chromosomal characterization of Amazonian freshwater stingrays with evidence for new karyomorphs and XX/XY sex chromosomes

description: Abstract Cytogenetic studies in the subfamily Potamotrygoninae have provided valuable insights into the understanding of the evolution and diversification of its species. In the present study, the chromosomal features of seven nominal potamotrygonin species are provided: Plesiotrygon iwamae (2n=74, FN=120), Potamotrygon amazona (2n=66, FN=107), P. constellata (2n=66, FN=110), P. leopoldi (2n=64, FN=102), P. motoro (2n=66, FN=106) from four different localities, and P. orbignyi (2n=66, FN=106), P. scobina (2n=66, FN=104), from Central Amazon. Additionally, we found a new karyomorph in P. wallacei. We considered the localization of Nucleolus Organizer Regions (NORs), as well as the pattern of constitutive heterochromatin, as species-specific characters. We found an XX/XY sex chromosome system in P. orbignyi, and we suggest that P. scobina and P. amazona also possess the same sex chromosome system. Overall, the chromosomal evolution in this group appears to have progressed towards a reduction in diploid number, with a concomitant increase in the number of bi-armed and nucleolar chromosomes.

title: Dietary patterns and factors associated in teachers of a private institution of higher education

description: Abstract Background Dietary pattern adopted by individuals seems to be related to sociodemographic factors, lifestyle and anthropometric parameters, and it may also reflect their health outcomes. Objective To identify dietary patterns and verify the associated factors among higher education teachers. Method Cross-sectional study with teachers from a South Brazil higher education private institution was carried out. It was evaluated the food consumption by a Food Consumption Markers Form and were collected sociodemographic, food, behavioral and anthropometric data. Factorial analysis of major components was performed to identify dietary patterns, and chi-square test and Poisson Regression to verify the association between exposure and outcome. Results Four dietary patterns described the food consumption of the 250 individuals, being two considered healthy (healthy and protein), constituted by health protector foods, and two (Western and snack), classified as mixed and of health risk, because it present both healthy food as those markers of an unhealthy eating, with predominance of the last. Teachers with characteristics of healthy life style showed larger adherence to healthy and protein patterns, and inverse relation with the Western. Those with greater actuation at the health area courses had larger adherence to protein pattern. Conclusion The large adherence of those with positive health aspects to healthy dietary patterns and their inverse relation to the Western pattern, they are probably related to the socioeconomic and demographic profile, characteristic of the population.

title: Continuously monitored lactose crystallization in a vibrated bed

description: Abstract The aim of this work was to evaluate the crystal size distribution (CSD) and microscopy of the crystalline phase in isothermal lactose crystallization, using a high seeding concentration (dense phase). In-line monitoring was carried out using Focused Beam Reflectance Measurement (FBRM) and Particle Vision Measurement (PVM) probes in a stainless steel trunk-conical shaped jacketed crystallizer. The vibratory shaking system consisted of two perforated discs coupled to a movable axle. A conventional crystallization unit, with a three-blade propeller attached to a stainless steel shaft, was used for comparison. Concentrated cheese whey, purified with an organic coagulant, and commercial lactose solutions were used. Crystallization was improved in the high-purity solutions. Microparticles and/or aggregates appeared before seeding, mainly in the purified cheese whey solution, in which there are impurities. Secondary nucleation was present in both the vibratory agitation and conventional rotary agitation systems, being intensified by increases in agitation. Crystallization in a vibratory system should be carried out with a vibration frequency of 250 rpm, since an increase to 400 rpm reduced the amount of larger crystals.

title: EFFICACY OF THE CLINICAL-INSTRUMENTAL ALGORITHM IN THE TREATMENT OF SPINAL TANDEM STENOSIS

description: ABSTRACT Objective: To conduct a multicenter analysis of the effectiveness of surgical tactics for treating patients with symptomatic tandem stenosis of the cervical and lumbar spine, based on a differentiated clinical-instrumental algorithm. Methods: The study included 97 patients with symptomatic tandem stenosis of the cervical and lumbar spine. The patients were allocated into 2 groups. The main prospective follow-up group (Group I) consisted of patients (n=46) who had undergone staged decompression/stabilization surgery according to the surgical tactics developed based on the differential clinical-instrumental algorithm. The clinical comparison group (Group II) (n=51) consisted of retrospectively recruited patients who, depending on the prevailing clinical condition, underwent primary surgery at the cervical level (29 cases) or at the lumbar level (22 cases). Results: The comparative analysis in Group I revealed significantly better parameters in the clinical and instrumental data. The total rates of postoperative surgical complications in the cervical and lumbar spine were 15% in Group I and 68% in Group II (p=0.0014). Conclusion: The multicenter analysis of the clinical-instrumental algorithm based on differential application of decompression/stabilization techniques enabled more rational and radical surgery, with less adverse outcomes, leading to earlier start of rehabilitation in the prospective group of patients (Group I), and an objective improvement in long-term clinical and functional outcomes.

title: The Language of the Tartu-Moscow Semiotic School and the Translations of Yuri Lotman’s Works in Brazil

description: ABSTRACT The use of codified and Aesopian language in the works of the semioticians who were members of the Tartu-Moscow Semiotic School was motivated by the desire to be understood by the School members and notunderstood by possible unwanted intruders from Soviet control organizations. One of the key terms they used was secondary modeling systems, which Vladimir Uspensky suggested to replace the word semiotics, associated with Western semiotics. By comparing Yuri Lotman’s essay Problems in the Typology of Culture (1967) to Lucy Seki’s translation of the essay into Brazilian Portuguese, which is part of the book Semiótica Russa [Russian Semiotics], edited by Boris Schnaiderman, I intend to verify if particularities of the original text, which resulted from the historical and political context in which the essay was produced, were maintained in the translation.
