title: QUALITY OF SLEEP, CHRONOTYPE AND PERFORMANCE IN STREET RUNNERS

description: ABSTRACT Introduction: Low-power laser therapy has among its aims to aid the recovery of biological tissues, attenuating the effects of muscle fatigue and contributing to the improvement of performance in athletes. Methodological aspects still limit the conclusions of the acute effect of laser therapy on muscular performance. Objective: To verify the acute effect of low-power therapeutic laser in the induced fatigue in biceps brachii of volleyball athletes. Methods: This was a randomized double-blind study, approved by Institutional Review Board of UNESP, Marília. Nineteen volleyball athletes of both sexes participated in this study. Electromyographic data were collected from the biceps brachii muscle in isometric exercise of the elbow flexion before and after the application of the therapeutic laser. A dumbbell with 75% of the force peak, obtained by a load cell, was used for the fatigue protocol. The volunteers then underwent laser (active or placebo) application on six points of the biceps brachii muscle. The EMG data were analyzed in the frequency domain using the Myosystem ®software. The distribution of normality was verified by the Shapiro-Wilk test, and repeated measures ANOVA (split plot) was used to test the interaction between time and group. Results: No significant interaction between group and time was observed for any analyzes variables, indicating that the irradiated group did not show advantages over the placebo group. Conclusion: After the proposed fatigue protocol, a single low-power laser application was not sufficient to produce positive effects on strength performance and on the electromyographic signal of the biceps brachii muscle of volleyball athletes.

title: Obtaining of Environmental Parameters in the Semiarid Region of Paraíba by MODIS Data

description: Abstract The spatial and temporal behavior of the surface net radiation (Rn) has been studied on ecosystems of semi-arid regions of the world and few studies have been intended for semi-arid region of Brazil, specifically in the Caatinga ecosystem. Therefore, the aim of this study was to use a methodology that does not require surface data to estimate the Rn in the semiarid region of Paraíba, from orbital MODIS data, and validate with data measured in experimental areas of Caatinga in recovery and degraded. Considering the results, it can be seen the effectiveness of the proposed methodology, and the same more precise in areas with the barest ground. According to the statistical analysis methodology showed a better quality of fit for the recovery area, with explained variance of 78% and a degraded area of 61%.

title: Pedagogical coordinators and diversity: between training courses and practices at elementary school

description: ABSTRACT This article presents practices that form the base of pedagogical coordinators’ formation and activities. The subjects work in five schools in the outskirts of Belém (Pará, Brazil), and try to imbed their methods on the new national curriculum guidelines for elementary teachers’ initial and ongoing formation, of July 1st, 2015. We intend to analyze how these professionals’ formation favors (or does not) teaching practices attentive to “the meanings of diversity and inequality”. We will analyze educational processes and teaching praxes of pedagogical coordinators who work at public primary and secondary schools, because we understand that pedagogical technicians grounded in theoretical and methodological procedures are crucial to the conduction of educational labor at school, since those professionals are among the ones who deal with the definition of internal educational policies. Through written and oral documents, conclusions suggest that the mismatch between formation for an ideal school and the meager knowledge of contextual relations of inequality structurally affects pedagogical practices.

title: The Mare Museum: between education, memories and identities

description: Abstract Interweaving memory, informal educational spaces and identity, analysis of the educational dimension of the Maré Museum in Rio de Janeiro shows that community identity may be strengthened through appreciation and reinterpretation of the history and construction of local memories. The Maré Museum generates visions ‘of ourselves and others’ by establishing a more subtle and constant dynamic between identities and their constructed memories and narrated stories in Boaventura de Souza Santos’ notion of a counter-hegemonic museum.

title: Growth and mycorrhizal colonization of maize plants treated with aqueous extracts from nonmycorrhizal weeds

description: Abstract: The objective of this work was to evaluate the influence of aqueous extracts of nonmycorrhizal weedy species on dry matter accumulation and assimilate partitioning of maize plants, with or without Cetraspora pellucida inoculation. The experiment was carried out in pots, in a completely randomized design, in a 5x2 factorial arrangement consisting of four plant extracts (purple nutsedge, guinea-hen weed, slender amaranth, and knotweed), a control irrigated with water, and two conditions (mycorrhizal and nonmycorrhizal maize plants), with four replicates of each treatment. Plants were irrigated with aqueous extracts diluted at 15%. Root colonization (RC), shoot dry matter (SDM), root dry matter (RDM), and RDM/SDM were evaluated. Root colonization was not influenced by the extracts, and ranged from 41.5 to 65.2%. Shoot dry matter of mycorrhizal (AM) and nonmycorrhizal (NM) plants was not influenced by the extracts; however RDM showed varying responses. Mycorrhization favored the production of RDM, and increased plant sensitiveness to the extracts. Guinea-hen weed extract increased RDM of AM plants, while the other extracts inhibited it. In NM plants, the production of RDM was benefited by slender amaranth extract, to the detriment of SDM. Mycorrhizal and nonmycorrhizal maize plants respond differently to aqueous extracts of nonmycorrhizal weeds.

title: MATURITY AND QUALITY OF APPLE FRUIT DURINIG THE HARVEST PERIOD AT APPLE INDUSTRY

description: ABSTRACT A database of maturity and quality indices was built by analysis of 62,807 samples of 100 ‘Gala’ apples and 29,053 samples of 100 ‘Fuji’ apples at harvest, over 11 years (2005-2015) in an apple industry warehouse. Apple fruit were harvested in Fraiburgo (SC), São Joaquim (SC) and Vacaria (RS). Data on firmness, starch index (SI), soluble solid content (SS), titratable acidity (TA), size and grades (external appearance) of apple fruit were submitted to linear and nonlinear regression analyses. Each fruit was graded by analysis of external qualities (color and surface blemishes) following Brazilian legal standards. At apples industry, the harvest period extended from 3rd to 15th week of the year for ‘Gala’ and from 10th to 22nd week of the year for ‘Fuji’ apples, although approximately 70% of total production for ‘Gala’ and ‘Fuji’ apples was harvested in a period of 4 and 6 weeks, respectively. Average maturity of 11 years varied from the 1st to the last week of harvest as follows: ‘Gala’ apples: 17.9 to 14.2 pounds (firmness), 4.0 to 6.1 (SI), 12.2 to 13.1% (SS) and 5.7 to 3.9 meq 100 mL-1 (TA). ‘Fuji’ apples: 17.1 to 14.3 pounds (firmness), 3.9 to 6.4 (SI), 12.9 to 14.4% (SS), 6.2 to 3.8 meq 100 mL-1 (TA). Approximately 48% of ‘Gala’ samples and 45% of ‘Fuji’ samples had firmness higher than 17 and 16 pounds, respectively, intended for long term storage, while 6% of ‘Gala’ samples and 8.5% of ‘Fuji’ samples had firmness lower than 14 pounds, intended for marketing shortly after harvest. The frequency of apple samples graded as Extra, Cat1, Cat2, Cat3 and out of category were 6%, 32%, 34% and 6% for ‘Gala’ apples and 5%, 39%, 33%, 18%, 5% for ‘Fuji’ apples.

title: Phytosterols in the Treatment of Hypercholesterolemia and Prevention of Cardiovascular Diseases

description: Abstract Phytosterols are bioactive compounds found in foods of plant origin, which can be divided into plant sterols and plant stanols. Clinical studies consistently indicate that the intake of phytosterols (2 g/day) is associated with a significant reduction (8-10%) in levels of low-density lipoprotein cholesterol (LDL-cholesterol). Thus, several guidelines recommend the intake of 2 g/day of plant sterols and/or stanols in order to reduce LDL-cholesterol levels. As the typical western diet contains only about 300 mg/day of phytosterols, foods enriched with phytosterols are usually used to achieve the recommended intake. Although phytosterols decrease LDL-cholesterol levels, there is no evidence that they reduce the risk of cardiovascular diseases; on the contrary, some studies suggest an increased risk of atherosclerosis with increasing serum levels of phytosterols. This review aims to address the evidence available in the literature on the relationship between phytosterols and risk of cardiovascular disease.

title: Use of Organic Acids and A Competitive Exclusion Product as Growth Promoter and Salmonella Enteritidis Control in Commercial Turkeys

description: ABSTRACT It is estimated that Salmonella causes one million illnesses in the United States annually, with 19,000 hospitalizations and 380 deaths. There are various serotypes of this bacterium, and the serotypes Typhimurium and Enteritidis are commonly isolated from outbreaks and, in most cases, present resistance to the antibiotics utilized in clinical medicine. One of the current theories to explain the emergence of bacterial resistance is the continuous use of antibiotics as growth promoters in animal feeds. Despite the lack of evidences that antibiotic growth promoters cause bacterial resistance, the poultry industry has explored strategies to reduce or to eliminate the use of antibiotic growth promoters in the production chain, including the improvement of biosecurity programs, use of vaccines, genetic selection, and the feeding of other additives, such as organic acid blends (OAB) and competitive exclusion (CE) products. This study aimed at evaluating the effect of the continuous dietary supplementation of an OAB and a CE product on the growth performance, pH of the crop and cecal contents, control of Salmonella Enteritidis (SE) in the cecal content, and acute-phase protein serum levels in starter commercial turkeys. The additives promoting similar results as antibiotics under controlled experimental conditions should be further evaluated on commercial farms to allow their utilization under practical conditions. Supplementing commercial turkey diets with the evaluated OAB and CE product may reduce SE load. Serum OVT and AGP levels can be used as effective and fast indicators of infection, including that by SE.

title: Live Performance, Carcass, and Bone Quality Responses of Grower and Finisher Broilers to Dietary Metabolizable Energy Levels

description: ABSTRACT Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days of age. There are many evidences that broilers changed their feed intake capacity due to genetic selection, especially when good quality pellets are fed, which suggests that modern broiler strains may achieve good performance when fed low metabolizable energy levels. The objective was to evaluate the energy efficiency, performance parameters, bone parameters, and carcass yield of 22- to 42-d-old broilers fed diets with energy levels below or above their requirements, while maintaining the density of all other nutrients. In total, 900 male broilers were distributed in a randomized block design, with five treatments consisting of five ME levels (2850, 2950, 3050, 3150 and 3250 kcal/kg). As expected, increasing dietary metabolizable energy reduced feed intake, feed conversion ratio, and energy efficiency. Interestingly, body weight, carcass and cut yields, and bone quality were not affected (p&gt;0.05) by dietary ME levels. In conclusion, 22- to 42-d-old broilers fed pelleted and crumbled diets containing 2,850 to 3,250 kcal ME/kg (14% difference) achieved the same body weight and carcass yield at slaughter. The results show that energy efficiency may provide a more accurate interpretation of broiler performance than feed conversion ratio, and that broilers are able to change their feed intake, indicating an opportunity to improve their nutritional management.
