title: Comparison of subcutaneous inflammatory response to commercial and engineered zinc hydroxyapatite implants in rabbits

description: ABSTRACT Hydroxyapatite (HA) is widely used as a biomaterial for bone repair and metallic prostheses coating. The main limitations of the current commercial synthetic hydroxyapatite compounds include high cost and decreased availability, especially for veterinary medicine purposes. Additionally, it is thought that HA biocompatibility and bioactivity could be enhanced by the addition of metal compounds. The objective of this work was to compare the subcutaneous tissue response of commercial and engineered hydroxyapatite obtained from the bovine femur diaphysis mixed with different concentrations of hexa-hydrated Zinc Nitrate in rabbits. Twenty-Five New Zealand female rabbits were used. Five treatments were done according to HA composition (commercial HA, no Zn-HA, 0.1M Zn, 0.2M Zn, and 0.3M Zn). Each treatment was evaluated at five time-points (8, 15, 30, 60 and 90 days post-implantation). Histopathologic analysis was performed to assess inflammation by polymorphonuclear cells infiltration, neovascularization, and fibrosis. Results obtained in this work suggest that general inflammation decreased after 60 days of implantation regardless of Zn concentration. Fibrosis score was increased in the commercial HP compared to control and Zn-hydrated HA. This paper shows that bovine hydroxyapatite is a biocompatible material regardless of nitrate Zinc concentration and has the same properties of commercial hydroxyapatite.

title: SPECTROSCOPIC CHARACTERIZATION OF PEDOT:PSS CONDUCTING POLYMER BY RESONANCE RAMAN AND SERRS SPECTROSCOPIES

description: Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) synthesis was monitored by resonance Raman (RR) and surface-enhanced resonance Raman scattering (SERRS) spectroscopies and both the oxidation of the polymer and the effects of chain length were assessed by vibrational analysis. It was supported by theoretical models of oligomers, with charge ranging from 0 to +6 and size varying from 2 to 16 3,4-ethylenedioxythiophene (EDOT) repeat units, described through density functional theory. The symmetric CαCβ stretching band observed at ca. 1426 cm-1 shifts to higher wavenumbers for reaction times varying from 2 to 9 hours and stabilizes at intermediate wavenumbers for longer times. The former behavior was ascribed to the increase of concentration of oxidized species, which was corroborated by calculated wavenumbers for oligomer models when their charges changed from neutral to +6. The behavior observed for longer reaction times was associated with the growth of chains. It was also observed through SERRS spectroscopy that small chains of the polymer, obtained in the early time of the synthesis, adsorbs on gold nanoparticle surfaces through interactions via oxidized residues. In this way, RR and SERRS spectroscopies were valuable tools to follow the synthetic procedures of PEDOT:PSS, allowing the determination of the structural evolution of the polymer.

title: Eco-epidemiological study on sandflies and environmental aspects related to the transmission of leishmaniasis in a municipality of Minas Gerais, Brazil, 2015-2016

description: ABSTRACT The aim of this study was to evaluate Leishmania vectors and investigate the environmental and climatic characteristics related to their transmission. This was a prospective eco-epidemiological study involving the systematic collection of sandflies and a canine serological survey in areas of municipality in Brazil. Blood samples from 1,752 dogs were examined to test for canine visceral leishmaniasis (VL). An entomological evaluation was carried out using 24 light traps in the peridomicile and intradomicile areas of 12 households for 12 months. Climate variables were analyzed using a simple Spearman correlation and a spatial analysis via the fuzzy logic method and K function. The prevalence rate of canine VL was 4.1% and 7.1% in the two areas that were studied, respectively. The entomological study resulted in the capture of 431 sandflies. Most (74%) of the specimens were captured in the peridomiciliary area, and 5.6% of the samples that were analyzed using molecular biology were positive for Leishmania spp. In particular, Leishmania infantum was found in 100% of the positive samples. The spatial analysis showed that one particular area presented a higher concentration of high-density overlapping points of Lutzomyia longipalpis and seropositive dog populations, indicating a higher risk of the concomitant occurrence of both events. The results show that a parasite-reservoir-vector interface is active in the studied areas.

title: Blood pressure measurement by oscillometric and auscultatory methods in normotensive pregnant women

description: ABSTRACT Objective: to compare blood pressure values obtained by auscultatory and oscillometric methods in different gestational periods, considering cuff width. Method: it is a cross-sectional and quasi-experimental study approved by the Research Ethics Committee. The sample consisted of 108 low-risk pregnant women. Blood pressure measurements were performed in gestational periods of 10-14, 19-22 and 27-30 weeks. Results: The oscillometric device presented values similar to the auscultatory method in systolic blood pressure, but overestimated diastolic blood pressure. Underestimation of blood pressure occurred when using the standard width cuff rather than the correct width cuff in both measuring methods. Conclusion: Verification of brachial circumference and use of adequate cuffs in both methods are indispensable to obtain reliable blood pressure values in pregnant women. We recommend performance of additional studies to evaluate diastolic blood pressure overestimation by the Microlife 3BTO-A.

title: Uma Nova Proposta para a Obtenção da Complexidade de Pior Caso do ShellSort

description: ABSTRACT The worst-case time-complexity of the ShellSort, a comparison sorting algorithm, depends on a sequence of steps given as input. Each step consists of an integer representing an index offset of the pairs of elements that should be compared during the sorting of an input array. Such a complexity is known only to some specific sequences. In this work, we use a relation between the ShellSort and Frobenius number to present a new algorithm that provides an upper bound on the number of comparisons that ShellSort performs, for any given array and sequence of steps. We apply this algorithm, together with an empirical complexity analysis, to study sequences whose worst-case complexities are known through analytical method. We show that the empirical approach succeeded in determining such complexities. Based on such positive results, we extend the study to sequences for which the worst-case complexities are unknown.

title: Association between feed efficiency and carcass finishinging gain of Nellore cattle

description: ABSTRACT This study aimed to estimate the phenotypic association between feed efficiency and gain in carcass finishing of young Nelore bulls. Information from 98 young Nelore bulls participating in two feed efficiency tests using the Growsafe® electronic trough system, carried out in the years 2015 and 2016, at the Capim Branco farm of the Universidade Federal de Uberlândia was used .The feed efficiency tests lasted for 91 days, with 21 days of adaptation and 70 days of evaluation. The animals had a mean age at the beginning and end of the confinement of 19.98 and 22.16 months, and mean weight initial and end of 428.17 and 542.27kg, respectively. It was verified that most efficient animals deposited less fat, and the efficient animals deposited more fat during the evaluation period at the confinement. It was observed that there is a low magnitude phenotypic association (0.29) between the residual feed intake (RFI) and the gain in carcass finishing (GACAB). Thus, it can be inferred that by selecting lower values of residual feed intake there will be some negative interference in GACAB. It was concluded that the most efficient animals (negative RFI) may present lower deposition of subcutaneous fat, influencing the carcass quality of Nelore cattle.

title: Performance, carcass characteristics and ingestive behavior of steers fed with silages of different maize hybrids

description: ABSTRACT The objective of this study was to evaluate the performance, carcass characteristics and ingestive behavior of feedlot steers fed with three maize hybrids: Maximus VIP3, Defender VIP and Feroz VIP. The experiment lasted 112 days, weighing animals four times, every 28 days. The experimental diets were formulated and constituted by maize silage and pelletized ration in a 50:50 ratio (dry basis). Regardless of the hybrid used, there was an increase in the intake of dry matter with the advance in feedlot evaluation period (9.15, 9.14, 9.35 and 9.59kg day-1, in the first, second, third and fourth weighing, respectively). The type of maize hybrid silage influenced weight gain of animals differently, with a final mean of 1.413kg for animals fed with Maximus VIP3, 1,375kg for those fed with Defender VIP and 1,184kg for those fed with Feroz VIP. The animals fed with Feroz VIP hybrid silage showed higher carcass gain efficiency and were more active in the number of times they went to the feeder. Although the three evaluated hybrids resulted in good animal performance, the carcass characteristics did not change; nevertheless, the hybrid Maximus VIP3 is recommended for its superior bromatological composition.

title: Retrospective study of allometric relationship between heart rate, electrocardiographic parameters and bodyweight in dogs

description: ABSTRACT The allometric relationship between bodyweight (BW) and heart rate (HR) has been described as inversely proportional in domestic species, but that has been refuted. The relationship between HR and electrocardiographic variables is described in literature. However, studies about the variation and influence of factors on the hemodynamic and electrocardiographic parameters in dogs are not abundant. As the metabolic rate is defined as the production and dissipation of heat by the body surface area (BSA) in m², it is essential to define that relationship. A retrospective study was conducted to analyze the correlation between HR, ECG parameters and BW in dogs. One thousand electrocardiographic tracings were analyzed in addition to the ECG parameters and clinical data such as gender, age and bodyweight. The determination of BSA was performed as follows: BSA (m2) = (10.1 x bodyweight 0.67) X 10-4. When the unified groups were analyzed, there was a negative but weak correlation (r= -0.14, P&lt; 0.0001) between bodyweight and HR. There were differences between weight groups regarding electrocardiographic variables. There is no allometric relationship between BW and HR in dogs. Weight was associated with changes in ECG variables.

title: Food and nutrition security in South America and the Brics: developments and uncertainties on the horizon

description: Abstract The article begins with an assessment that the global capitalist system is intrinsically unequal. The data are those of the performance of national economies. A problematization of this hypothesis in the most recent post-crisis period of 2008 exists given the works that sustain that there is a structural change in favor of the developing economies. The theoretical elements systematized in the article corroborate the hypothesis that the system remains unequal, although with marginal changes. A second part presents the systematization of social data related to Food Security and Nutrition for the region of South America and the BRICS. Social progress is linked, but the indicators show a situation still far removed from the reality of developed economies. The Principal component analysis (PCA) procedure is used.

title: Organizational climate and teamwork at the Family Health Strategy

description: ABSTRACT Objective: to measure the organizational climate in the work of professionals from Family Health Strategy (FHS) teams. Method: a cross-sectional study carried out with 458 professionals belonging to 72 FHS teams in a municipality in Southern Brazil. Data collection occurred between March and July of 2016 with self-application of the Team Climate Inventory (TCI). Data were analyzed by means of a non-parametric ANOVA. Results: “Team Participation” was the best-rated domain (8.11), while “Task orientation” was the worst (7.51). Nurses obtained the highest mean in TCI (8.05), and dentists, the lowest (7.45). Conclusion: TCI is an appropriate and innovative tool for assessing the teamwork climate at the FHS. Identifying fragilities such as “task orientation” and relationships among professional categories of the team supports the planning of actions for organizational climate improvements and teamwork at the FHS.

title: An Experimental Analysis of Three Pseudo-peripheral Vertex Finders in conjunction with the Reverse Cuthill-McKee Method for Bandwidth Reduction

description: Abstract. The need to determine pseudoperipheral vertices arises from several graph-theoretical approaches for ordering sparse matrix equations. The results of two algorithms for finding such vertices, namely, the George-Liu and Kaveh-Bondarabady algorithms, are evaluated in this work along with a variant of the Kaveh-Bondarabady algorithm. The results suggest that the well-know George-Liu algorithm dominates the other two pseudoperipheral vertex finders mainly when considering the computational times of the algorithms.
