title: Influence of food intake and use of supplements in performance of brazilian para-athletes

description: ABSTRACT Introduction: Weightlifters seek to increase strength in relation to body mass using resistance training and nutrition as performance-enhancing tools. Despite the benefits provided by adequate nutritional planning, many athletes make use of unsuitable strategies, manifested by worse body composition and sports performance. Objective: Analyzing energy and protein consumption and the use of nutritional supplements in para-athletes in order to assess the influence of dietary strategy on performance. Methods: Personal data, anthropometric measures, as well as information on eating behavior and the competition have been collected from 24 male paralympic weightlifters. Results: The amount of calories and macronutrient intake in food averaged 2,235.8 ± 694.92 kcal, 27 ± 11.55% proteins, 46 ± 8.17% carbohydrates and 27 ± 8.57% lipids. Of the athletes studied, 87.5% reported using dietary supplements. Athletes with higher body mass index (BMI) exhibited lower energy and relative protein intake, higher sum of skinfolds and similar performance to the other athletes under study. Conclusion: The strategy used by athletes with higher body mass index did not directly improve performance and had a negative influence on body composition. This fact is probably due to inadequate adjusting of supplementation and diet.

title: Effect of acute caffeine supplementation in biochemical response during endurance exercise in rats

description: ABSTRACT Introduction: Caffeine is presently the most consumed substance in the world and, associated with physical exercise, brings important achievements in performance. Objective: To investigate the biochemical effects of acute caffeine supplementation after endurance exercise in Wistar rats. Methods: Twenty-seven male Wistar rats have been used, weighing 357 ± 73 g, randomly distributed in three groups: 1) Control (without supplementa-tion and exercise), 2) Saline (saline+ exercise), 3) Caffeine (6 mg/kg caffeine + exercise). Supplements have been administered 50 minutes before the 60-minute swimming test. Immediately after swimming, the animals have been sacrificed for blood sampling and biopsy of liver and muscle tissue. The levels of blood glucose, triglycerides, serum lactate and concentrations of glycogen in liver and muscle have been analyzed. All results were expressed as mean ± SEM. The statistical analysis used was the ANOVA one way test, being considered statistically signi-ficant only P&lt;0.05. Results: Muscle glycogen and lactate did not differ between groups. Caffeine has preserved the levels of blood glucose and liver glycogen (P&lt;0.05). Caffeine has elevated the levels of plasma glycerol in 31.2% (P&lt;0.05), when compared to the group exercised without supplementation. Conclusion: The study reports that the use of pre-exercise caffeine promotes biochemical alterations that can improve metabolic efficiency during the endurance exercise.

title: Mosquitoes (Diptera: Culicidae) from crepuscular period in an Atlantic Forest area in Southern Brazil

description: Abstract Crepuscular period is one of the factors that may influence the biting activity of mosquitoes. Many of these insects have a peak activity in this period. The purpose of this study was to investigate the afternoon crepuscular activity of Culicidae in a remaining area of Atlantic Forest in western Santa Catarina, southern Brazil. Moreover, the possible influence of abiotic factors, the abundance and species richness were verified. In order to better analyze the influence of crepuscular period in specific composition and abundance of mosquitoes, the dusk was divided into three periods: pre-sunset, sunset and post-sunset. At the end of the study, nine hundred and eight four specimens distributed in 12 genera and 23 species were collected. Trichoprosopon pallidiventer (Lutz, 1905) (59.76%), Aedes crinifer (Theobald, 1903) (8.13%), Ae. scapularis (Rondani, 1848) (5.89%) were the most abundant species. Spring time presented the greatest abundance and species richness. During the study, among the three periods evaluated, pre-sunset had the greatest abundance and post-sunset the lowest. Pre-sunset and sunset had the greatest similarity between species. Regarding to the abiotic factors evaluated seven and 15 days before sampling, they did not present significant correlation for the three most abundant species. However, temperature had a positive correlation to these species. Moreover, the correlation between collected species and its possible role as vectors of etiological agents of diseases was discussed.

title: Quantification of f loral abnormalities in a population generated from sexual polymorphism aiming at recurrent selection in papaya

description: ABSTRACT The aim of this study was to estimate the percentage of deformed fruits (carpelloid, pentandric, and bananoid), summer sterility, repeatability coefficients, and correlations among the variables for floral abnormalities; and select genotypes withthe lowest incidence of deformed fruits and summer sterility. In theexperiment, which involved 254 plants, traits were evaluated using the digital-phenotypic method and the obtained images were processed and analysed using ImageJ v1.48 software with the Cell Counter plugin. Summer sterility had the highest percentage of occurrence in the evaluated periods. Based on the quantificationof total abnormalities, the 30 genotypes with the lowest incidence offloral abnormalities were selected. Summer sterility is the main problem of the papaya crop in terms of floral abnormalities. The non-significant correlations between the traits: NDF/TNF+NFN (number of deformed fruits/number of fruits + number of fruitless nodes) and NFS/TNF+NFN (number of fruitless nodes/number of fruits + number of fruitless nodes); NDF/TNF+NFN and NFN/SUM(number of fruitless nodes/sum of abnormalities); andNFS/TNF+NFN and NDF/SUM (number of deformed fruits/sum of abnormalities) indicate that the variables are independent of each other. Of the 254 evaluated progenies, at least 30 were identified as having potential for selection, with lower occurrence of total floral abnormalities.

title: Environmental impacts of a reduced flow stretch on hydropower plants

description: Abstract In Brazil, given its privileged hydrology, the unexplored economic use of water resources has many dimensions, such as hydroelectric power. This energy will face increasingly rigorous social and environmental impact assessments (40% of potential is located in the Amazon region). Hydropower inventory studies conducted over decades, with solutions such as ecological river flows, that flood smaller areas and reduce natural river flows modifications, are being reviewed. The river extension from dam to the point where the waters are returned after the powerhouse is known as the Reduced Flow Stretch (RFS). Even mega-projects, such as the 11.3 GW Belo Monte dam, are designed with deviating flows reaching an astounding 13,000 m 3/s (excavated material higher than Panama Canal). RFS requires to be carefully studied to achieve appropriate ecological flows, since RFS flows increased reduces the plant's electricity production to the same installed capacity. Balancing RFS requirements and hydroelectric power remains a challenge and, clearly, there is no consensus. Here, we performed an analysis of the main environmental impacts caused by RFS requirements, considering the multiple water use specific for each dam site. The natural variability of river flows provides diversity of habitats and maintains the richness and complexity of biological communities. Therefore, the present study has great ecological, social and economic relevance, since proper evaluation of the RFS requirements avoids potential destabilization of biological communities and even loss of biodiversity. This type of arrangement was more common in dams located in headwaters of rivers, as in the slopes of the Andes mountain range, and in regions like the Alps. There are many hydroelectric plants in South America and Europe that have this type of arrangement of engineering works. But the times are different and the environmental impacts have to be better evaluated. A final aspect also involves the maintenance of ecological flows downstream of dams. Regularization reservoirs need to keep downstream, even if they do not have a TVR, adequate flows that represent minimally the seasonality of the river, with floods and droughts, that propitiate the maintenance of the ecosystems downstream. There are cases such as the Sobradinho Plant in the São Francisco River that has been much questioned in this regard, especially when the climate is changing in the basin, with long periods of drought, and with increasing water use. So this is a very important and increasingly current issue.

title: Methods of aril removal and lightness conditions on seeds physiological quality of sour passion fruits

description: Abstract Passion fruits species presents a larger economic importance for in natura consumption and industry. The main way to propagate these species is by seeds; however, the aril presence and environmental conditions may inhibit the seeds germination. In this sense, the objective of this study was to evaluate the effect of aril removal methods and light conditions on P. edulis var. flavicarpa seeds quality and germination. There were used five methods to remove the seeds aril: (1) friction on steel mesh sieve for 5 minutes; (2) friction with coarse sand on steel mesh sieve for 5 minutes; (3) immersion in lime solution at 10% (w/v), for 30 minutes; (4) fermentation in sugar solution at 10% (w/v), during 48 hours; and (5) natural pulp fermentation, during five days. The seeds were submitted to germination test at darkness and lightness, as well as, to length seedlings and emergence test. Regardless the aril removal method, the germination percentage was lower at lightness than darkness highlighting the natural pulp fermentation treatment, which presented 86% of seeds germinated. On the other hand, the aril removal methods did not affect the seedlings emergence, with emergence percentages ranged from 88 to 94%.

title: Distribution and fluctuations of backswimmers (Notonectidae) in a tropical shallow lake and predation on microcrustaceans

description: Abstract Notonectids are widely distributed in freshwaters and can prey on zooplankton in temperate lakes. However, its role in structuring the zooplankton community is unknown in tropical lakes. Thus, our objective was to study the notonectid Martarega uruguayensis in a Brazilian tropical shallow lake to evaluate its potential as a zooplankton predator. Its horizontal distribution was analized in the lake throughout one year in fortnightly samplings. Backswimmers were more abundant (mean density 162.9 ± 25.8 ind.m–2) in the cool-dry season, with a strong preference by the littoral zone (mean density 139.9 ± 17.5 ind.m–2). Laboratory experiments were undertaken with young and adult notonectid and the two most abundant cladocerans, Daphnia gessneri and Ceriodaphnia richardi, as prey. Predation by backswimmers in the laboratory showed that only juveniles fed on microcrustaceans (mean ingestion rate of 1.2 ± 0.2 Daphnia and 1.0 ± 0.2 Ceriodaphnia per predator per hour), without size selectivity. Adult insects probably have difficulties in detecting and manipulating small planktonic organisms. On the other hand, young instars might influence zooplankton community, especially in the littoral zone of the lake. This study does contribute to a better understanding of trophic interactions in tropical shallow lakes and is the first to investigate the predation of a notonectid on microcrustaceans from Lake Monte Alegre.

title: The Perme scale score as a predictor of functional status and complications after discharge from the intensive care unit in patients undergoing liver transplantation

description: ABSTRACT Objective: To assess the Perme mobility scale score as a predictor of functional status and complications in the postoperative period in patients undergoing liver transplantation. Methods: The sample consisted of 30 patients who underwent liver transplantation. The patients were evaluated at two time points to determine their perception of pain, degree of dyspnea, peripheral muscle strength, and functional status according to the Perme scale. The collected data were analyzed by descriptive and inferential statistics. To compare the means between the evaluations, Student's t test for paired samples was applied. In case of asymmetry, the Wilcoxon test was used. In the evaluation of the association between the quantitative variables, the Pearson or Spearman correlation tests were applied. Results: A total of 30 individuals who underwent liver transplantation were included. The patients were predominantly male, and the mean age was 58.4 ± 9.9 years. The most prevalent underlying pathology was cirrhosis C virus (23.3%). Significant associations of the time on mechanical ventilation with the Perme scale score at discharge from the intensive care unit (r = -0.374; p = 0.042) and the number of physical therapy treatments (r = -0.578; p = 0.001) were recorded. When comparing the results of the initial evaluation and the evaluation at hospital discharge, there was a significant improvement in functional status (p &lt; 0.001). Conclusion: Functional mobility, peripheral muscle strength, pain perception, and dyspnea are significantly improved at hospital discharge compared with those at inpatient unit admission.
