title: Obstructive sleep apnea and neurodegenerative diseases: A bidirectional relation

description: Sleep disorders are common during the clinical course of the main neurodegenerative diseases. Among these disorders, obstructive sleep apnea has been extensively studied in the last decade and recent knowledge regarding its relationship with the neurodegenerative process points a bidirectional relationship. Neurodegenerative diseases can lead to functional changes in the respiratory system that facilitate the emergence of apnea. On the other hand, obstructive sleep apnea itself can lead to acceleration of neuronal death due to intermittent hypoxia. Considering that obstructive sleep apnea is a potentially treatable condition, its early identification and intervention could have a positive impact on the management of patients with neurodegenerative diseases.

title: GLOBAL BECAUSE A SLAVEHOLDING ORDER: AN ANALYSIS OF THE URBAN DYNAMICS OF RIO DE JANEIRO BETWEEN 1790 AND 1815

description: Abstract Rio de Janeiro stands out as one of the few cities in the Atlantic world that have managed to bring together characteristics so particular and at the same time revealing of the global dynamics that marked the last decades of the eighteenth century and the first fifty years of the next century. On the one hand, its political centrality became evident with its elevation to the thirst for colonial power (1763), its transformation into the Court of the Lusitanian Empire (1808) and its choice as the capital of the Brazilian Empire (1822), the portion “Versailles Tropical “Of Rio de Janeiro coexisted with a city that, in the words of an English traveler, more seemed the” heart of Africa “; with blacks and blacks of different origins, performing an innumerable number of activities that yielded to Rio de Janeiro the honorable title of the largest slave city in the Americas. More than harming foreign travelers unaccustomed to everyday slavery, or creating practices of “little Africa” in its territory, the strong presence of Africans and their descendants under the aegis of slavery reveals yet another facet of Rio de Janeiro: a locus of the world, in which identities, trajectories and senses of the city were in dispute. The purpose of this paper is precisely to understand the political, economic and social dynamics that characterized Rio de Janeiro as an important center of this Afro-Atlantic world

title: Occurrence of the main bacterial and parasite agents on diarrhetic feces of buffalo calves in the states of São Paulo and Paraná

description: There are about 3 million buffalos in Brazil, spread through all of the Brazilian states; with mean annual growth of 12%. In spite of that, to the best of our knowledge few studies looking for advances in the industry have been done. Due to the etiological complexity of buffalo diarrhea and the lack of information in this area, this aimed at developing a clinical evaluation on the causes of buffalo calves bacterial and parasitical diarrhea in dairy farms of the states of São Paulo and Paraná. The survey was done in farms located in the cities of São João da Boa Vista, Dourado, Pirassununga, Registro, Pariquera Açu, Pilar do Sul (SP), and Santana do Itararé (PR). From March, 2010, to June, 2011, 53 diarrhea samples were collected and screened for endoparasite and bacteria; 45.28% (24) were positive for Eimeria spp.; 26.42% (14) had Strongyloidea; and 1.88% (1) had Toxocara vitulorum. In the bacteriological test, 97.83% (45) had E. coli, but only two were considered pathogenic (E. coli STEC); 2.17% had Klebsiella pneumonia and none presented Salmonella spp. In this study, the mainly causative agent of buffalo diarrhea was Eimeria spp., and the poor hygiene in installations and breeding failure are important factors on this diarrhea occurrence.

title: Diet quality of a nursing staff of a philanthropic hospital in Pelotas/RS

description: Abstract Background An individual's eating habits directly impact on their health conditions, nutritional status, in addition to influencing their daily activities, including work and studies. Objective To evaluate the diet quality of a nursing professionals. Method Behavioral and feeding variables were collected through a questionnaire based on the VIGITEL - Surveillance of Risk and Protection Factors for Chronic Diseases. The Diet Quality Index was developed from the diet reported by professionals, assigning points to each food/practice according to frequency of consumption/achievement. Associations between outcome and exposures were evaluated through T Test and ANOVA. Results Among the 272 subjects, high consumption of legumes, vegetables and fruits was observed, and consumption reduced of chicken and milk, and that the participants did not present the habit of exchange the lunch for snack. There was also a high consumption of soft drinks, artificial juices and sweets. The mean of the diet was 16.8 out of a total of 30 points and higher scores were associated with older individuals, who reported practicing physical activity and who did not consume alcoholic beverages, nursing assistants and those who did not have any other professional activity. Conclusion The poor quality of the diet of the professionals evidenced the need for clarification about healthy habits.

title: SELECTION FOR THE DEVELOPMENT OF BLACK EYE COWPEA LINES

description: ABSTRACT Cowpea bean is a socioeconomically important legume that contribute to generate employment and income. This species presents great grain variability, and the commercial subclass black eye stands out as a very appreciated grain in Brazil and abroad, thus requiring the development of new cultivars. The objective of this work was to evaluate and select lineages of commercial black eye cowpea, based on simultaneous, and direct selection. First, 105 progenies and four controls were evaluated using the Federer's augmented block design. Seventy-seven progenies, selected from this evaluation-first selection cycle-and four controls were evaluated in three environments, using a simple 9×9 lattice design. Based on this evaluation, the second selection cycle was possible, resulting in 24 progenies. The gain by direct selection was lower than the predicted gain for grain yield in the first cycle, indicating that the selection was not effective. This result was probably due to the reduced genetic variability caused by the selection pressure. In the second cycle, the predicted and observed gains were similar, indicating that much of the expected gain was observed. The predicted and observed gains, with simultaneous selection based on the rank sum selection index, were similar in the first and second cycle. The simultaneous and direct selections resulted in genetic gains for grain yield in the two selection cycles, making it possible the selection of high grain yield lineages.

title: THE COLLEGE OF APPLICATION/UFRGS AND THE DIFFUSION OF EXPERIMENTAL SECONDARY CLASSES: BETWEEN THE FILE AND THE ORAL MEMORY (1959-1981)

description: Abstract The article investigates memories of the College of Application (CAp/Ufrgs), an educational institution that was established as a sort of pedagogical vanguard in the Porto Alegre society. We discuss the implementation of the secondary experimental classes, as an appropriation of the French Nouvelles Classes. Oral and archival documents were examined and allowed to infer that the CAp is the product of his time, represents the propagation of discourses of educational renewal, especially the studies of Psychology that have come to occupy relevant space in school issues and teacher training. The educational practices of the CAp show the cultural circularity between educators, especially French and Brazilian, who for many years were linked by the missions and pedagogical exchanges.

title: LEVELS OF CALCIUM AND CALCIUM: PHOSPHORUS RATIO IN DIETS FOR LAIYNG HENS AGED 24 TO 40 WEEKS

description: Abstract The objective of this study was to determine the nutritional requirement for calcium and the best calcium:phosphorus ratio in the diet for laying hens from 24 to 40 weeks of age. 324 Hy-Line W-36 birds were distributed in a completely randomized design in 3x3 factorial scheme, consisting of three levels of calcium (3.9, 4.2, and 4.5%) and three calcium:phosphorus ratios (9.3, 10.53, and 12.12:1) totaling nine treatments, six replicates and six birds each. We evaluated performance, egg quality, bone characteristics, balance of calcium and phosphorus, and mortality. There was no interaction (P&gt; 0.05) between calcium levels and calcium:phosphorus ratio for the variables, but levels of calcium affected (P &lt;0.05) weight and shell percentage, calcium in the shell, lost eggs, consumption of calcium and phosphorus, calcium and phosphorus excretion, and retained calcium and phosphorus. The calcium:phosphorus ratio affected significantly (P &lt;0.05) feed intake, weight gain, feed conversion per dozen eggs, egg mass, calcium and phosphorus intake, phosphorus excretion, and retained phosphorus. Diets containing 4.5% calcium and the calcium:phosphorus ratio of 12,12:1, corresponding to a calcium intake of 3.71 g/hen/day and phosphorus of 306 mg/bird /day, guarantee satisfactory performance in diets for laying hens from 24 to 40 weeks.

title: Litterfall: A Bio-indicator for Edge Effect in a Semi-deciduous Seasonal Forest

description: ABSTRACT This study aimed to evaluate the use of litterfall as an indicator of fragmentation in a Semi-deciduous Seasonal Forest in Além Paraíba, MG, Brazil. Litterfall was collected monthly for one year in conical collectors (0.25 m2 of surface), located at seven distances from the forest edge: 10, 30, 60, 100, 160, 250 and 350 m. The litterfall was dried in an oven and separated (leaves, branches, reproductive structures, miscellaneous). Litterfall was greater near the forest edge, probably due to a predominance of species with high leaf deposition (pioneers and deciduous). Litterfall had peaks at the beginning of the rainy season for the average obtained from the seven distances from the forest edge. The edge effect did not clearly influence the contribution of the fractions or the seasonality of total litterfall.

title: Diversity of Arbuscular Mycorrhizal Fungi in an Amazon Environment after Mining

description: ABSTRACT At the Brazilian Amazon forest, studies were carried out to estimate the community of arbuscular mycorrhizal fungi (AMF), from this it was used a bioassay of dilutions of samples collected from preserved and regenerated areas after bauxite extraction. To regenerate areas, tree species were introduced and samples were taken after 2, 6, 12, and 16 years, the spores obtained were compared to those obtained by direct extraction and the number of species recovered from the bioassay was significantly higher. Therefore, the species founded after different periods regeneration was similar to the ones from the native forest. Since the early years of revegetation, the number of rare species was high with strong dominance of G. macrocarpum. Among older communities this high dominance decreased while at the same time, there was an increase in the number of individuals from other AMF species, concluding that the number of species did not change with the age of the revegetation.
