title: Aloe vera as vehicle to mineral trioxide aggregate: study in bone repair

description: AIM: Mineral trioxide aggregate (MTA) was associated to Aloe vera to verify the coadjutant action of that medicinal plant in the bone neoformation process in tibia of rats.MATERIAL AND METHOD: 36 male rats (Rattus norvegicus) were used, divided into two groups of 18 rats each. Two circumferential bone defects with approximately 5 mm in diameter were made on the right tibia of each animal: the upper defect was filled with blood coagulates in both groups to serve as experimental control and the lower defect was filled with MTA and Aloe vera in experimental (group E1) and MTA and distilled water in experimental (group E2). Seven, 15 and 30 days after surgery, six animals from each group were euthanized and the right tibia of each animal was removed for histological analysis.RESULT: Histologically, experimental group E1 presented better results for the two variables, inflammation [at seven days (p=0.045)] and bone formation [at seven days (p=0.018) and 30 days (p=0.034)], compared to the E2 group.CONCLUSION: The association of MTA and Aloe vera showed potential to reduce the effects of the inflammatory cascade and promote bone neoformation making it to a promising proposal for future use in endodontic therapy.

title: Hippocampus discovery First steps

description: The first steps of the discovery, and the main discoverers, of the hippocampus are outlined. Arantius was the first to describe a structure he named "hippocampus" or "white silkworm". Despite numerous controversies and alternate designations, the term hippocampus has prevailed until this day as the most widely used term. Duvernoy provided an illustration of the hippocampus and surrounding structures, considered the first by most authors, which appeared more than one and a half century after Arantius' description. Some authors have identified other drawings and texts which they claim predate Duvernoy's depiction, in studies by Vesalius, Varolio, Willis, and Eustachio, albeit unconvincingly. Considering the definition of the hippocampal formation as comprising the hippocampus proper, dentate gyrus and subiculum, Arantius and Duvernoy apparently described the gross anatomy of this complex. The pioneering studies of Arantius and Duvernoy revealed a relatively small hidden formation that would become one of the most valued brain structures.

title: GROWTH AND SEED YIELD OF SUNFLOWER ON SOIL FERTILIZED WITH CASSAVA WASTEWATER

description: ABSTRACT Cassava wastewater is the liquid residue of the cassava flour processing and its application to the soil as fertilizer for agricultural crops is a good alternative to sources of nutrients for plants. In this context, the objective of this work was to evaluate the growth and seed yield of sunflower on soil fertilized with cassava wastewater. A randomized block experimental design with four replications was used, with six cassava wastewater rates (0, 8.5, 17, 34, 68 and 136 m3 ha-1) and six plant sampling times (15, 30, 45, 60, 75 and 90 days after sowing), using the sunflower cultivar Helio-250. The evaluated variables were total leaf area, leaf area index, leaf area ratio, specific leaf area, leaf weight ratio, shoot dry mass and sunflower seed yield. The use of cassava wastewater rate of 136 m3 ha-1 increases the seed yield, leaf area, leaf area index and shoot dry mass, and results in lower leaf area ratio, specific leaf area and leaf weight ratio of sunflower (cv. Helio-250) crops.

title: Asymmetries and similarities in horse production in the Southern of Brazil and Argentina: productivity, health and trade aspects

description: AbstractThis study was carried out in order to verify the asymmetries and similarities in horse breeding in the Brazilian South region and Argentina, analyzing the productive, health and trade aspects. Data collection were performed with questionnaires in fieldwork (primary sources) and bibliographic searches and surveys (secondary sources). The sample consisted of horses breeders in Brazil, Rio Grande do Sul State, and in Argentina. The questionnaire was based on the Brazilian Study of Horse Agribusiness Complex, divided into: Production Aspects, Health Issues and trade aspects. Descriptive data analysis and relative frequencies were compared using the chi-square (χ2) test at 5% probability. It was observed that there was a similarity in several aspects related to the breeding and trade horse agribusiness, whereas in the health aspects there was asymmetry in certain aspects. In the Southern Brazil, 29.0% of the owners live in the breeding farm and 67.7% have another remunerated activity. There was a similarity in the endoparasites system control and an asymmetry in the ectoparasites control. There was a higher percentage of diseases control in Argentina, which may be related to technification and qualification of workforce. However, regarding the equine sanitary control, there was a similarity between the farms of Southern Brazil and Argentina. Despite of all asymmetries and similarities, there is a relevance of horse agribusiness on generating jobs and income source, as well as the cultural and economic contribution in both countries. Furthermore, there is a necessity of public policies from government authority to promote the horse industry.

title: Third molars stage of mineralization and its relation to chronological age: Midwest Brazil sample

description: INTRODUCTION: In recent years some studies have been taken to evaluate the applicability of the third molar development analysis in the estimation of human age. However, just a few studies with the population from Midwest Brazil were performed.OBJECTIVE: The present study aim to analyze the relationship between the lower third molars development stage and the chronological age of individuals in Midwest Brazil region.MATERIAL AND METHOD: This cross-sectional observational study comprised a total of 120 panoramic radiographies of patients aged 5-22 year-old, males and females, attended between 2007 and 2012 at our Institution. The third molars development stage was analyzed based on the method described by Nolla and related with the chronological age of the individual by linear regression. It was considered significant values for linear tendency between 0-1.RESULT: It was observed that both, male patients (R2 = 0.7495) and females (R2 = 0.8507), showed a linear correlation between the third molars development stage and chronological age. It was also noted that the development stages coincided with similar ages in both genders.CONCLUSION: There is a relationship between chronological age and developmental stage of the third molars in the sample studied. These data suggest that this type of analysis should be individualized according to the population characteristics.

title: Matricial Support and Arterial Hypertension Control

description: Abstract Background: A continuing education program for health professionals improves their performance and increases hypertension control rates. Objective: To estimate the prevalence of hypertension control and therapeutic inertia among adults treated at Primary Health Care Units after a continuing education program focused on cardiology for health professionals. Methods: A cross-sectional study was carried out, which included cluster sampling and analysis of medical records. We evaluated 463 patients with high blood pressure and analyzed the blood pressure, medications, and therapeutic increments in 2013, which were compared to the data obtained in 2007. Results: There was prevalence of female patients and appointments at the Family Health Care Units. The age ranged between 24 and 92 years (mean of 61.7 years). There was a reduction in the mean blood pressure (148.62/91.60 ± 23.52/14.51 mmHg to 137.60/84.03 ± 21.84/12.72) between the first and last records, and BP control in 58% of the sample, that is, higher than the 36.6% found in 2007. In the analyzed period, there was a therapeutic increment of 39% in appointments, which benefited 52% patients with high blood pressure, higher than the 12% and 29.5%, respectively, found in 2007. The mean number of drugs per patient increased from 1.85 to 2.05, with a predominance of diuretics and angiotensin-converting-enzyme inhibitors. Conclusion: There was a reduction in the clinical inertia and increased control of arterial hypertension was observed, compared with the findings of the previous study. The result suggests that the matricial support program for health professionals and other measures to improve disease control in the Primary Health Care Units were effective.

title: Biomass and Carbon in a Seasonal Semideciduous Forest in Minas Gerais

description: ABSTRACT The objective of the present study was to quantify the biomass and carbon stock in a Seasonal Semideciduous Forest remnant in southern Minas Gerais. Forest inventory data taken between 2010 and 2013 in permanent plots, was used to estimate biomass with an allometric equation. Basic wood density (Db) and carbon content were determined in the laboratory and the carbon stock was obtained by multiplying biomass by carbon content. The species with the lowest and highest Db were Nectandra lanceolata (0.38 g cm-3) and Machaerium villosum (0.77 g cm-3). The species that showed the lowest and highest carbon content values were Casearia decandra (41.85%) and Nectandra oppositifolia (46.57%). The biomass stock for the area was 126.92 ± 0.09 t ha-1, which corresponded to 55.91 ± 0.05 t ha -1 of carbon stock and a periodic annual increment of 3.07 t ha-1 year -1.

title: Dehydration and chemical composition of Leucena (“Leucena leucocephala”) and Gliricidia (“Gliricidia sepium”)

description: SUMMARY The objective was to evaluate the chemical composition and time to reach the point of hay of Leucena (Leucena leucocephala) and Gliricidia (Gliricidia sepium). Samples were collected in time 0, 2, 4, 6, 8, 10, 12, 14, and 16 hours of drying to obtain dehydration curve for each species of forage. The design was completely randomized with nine treatments (9 times of dehydration x three replicates). Data for morphological characteristics of the species were subjected to statistical analysis of variance, and means were compared by Tukey test at 1% probability. For dehydration curve as a function of time, the data were subjected to regression analysis. The leaf:stem ratio was higher for Gliricidia in time and 16 hours of dehydration (P &lt;0.05). The rates dehydration of Composed samples of pod, stem and leaf of Gliricidia and Leucena showed a linear increase (P &lt;0.05) and the Leucena dehydration was most efficient. The dry matter content of Gliricidia and Leucena showed, respectively, 91.24% and 91.32% content, while the crude protein content was 18.64% and 17.7%. The fiber content neutral detergent corrected for ash and protein content was the 49.86% and 49.07, the neutral detergent insoluble protein content was 1.01% and 1.77%. The time to reach the point of Leucena and Gliricidia hay was 16 hours. The nutritional composition of hay Leucena and Gliricidia were satisfactory to be provided in the feeding of ruminant animals.

title: Factors associated to the practice of physical activity by Brazilian workers

description: ABSTRACT The factors associated with the practice of physical activity among Brazilian workers were evaluated. It is a descriptive, analytical, cross-sectional, quantitative study conducted with 82,019,207 workers by means of the National Survey by Household Sample of 2015. So to verify the association of physical activity practice among workers, Odds Ratio (OR) was estimated at p&lt;0.05 by means of a logistic regression model with a 95% Confidence Interval (CI). It was noted that only 31.7% of the workers practiced physical activity. The practicing probability decreased with age increasing, especially for males between 46 and 55 years old (OR 0.626, CI 0.565-0.693), as well as for female workers with children under 14 years old (OR 0.569, IC 0.474-0.682) facing high working hours. The practice of formal workers is 17.9% higher than among informal workers. Also, the increase in schooling as in salaries raised the chance by, respectively, 5.719 for those with 15 years or more of study and by 2.365 for those between 12 and 15 minimum salaries of income. Finally, the military personnel enjoyed a greater chance of practicing physical activity (OR 5.586, IC 3.572-8.736).
