title: Ozone saturation and decomposition kinetics in porous medium containing different hybrids of maize

description: ABSTRACT The objective of this study was to evaluate ozone saturation and decomposition kinetics in porous medium containing grains of different hybrids of maize. The following hybrids were used: common maize hybrid AG 1051, super sweet maize hybrids Tropical Plus, GSS 42072, GSS 41499 and GSS 41243. 1 kg grain samples with water contents of 13.0% (w.b.) were placed in glass containers with 3.25 L capacity. The grains were ozonized at the concentration of 1.28 mg L-1, at 25 ºC, with gas flow rate of 5.0 L min-1. Saturation time and concentration, half-life time and physical properties such as apparent specific weight, actual specific weight, porosity, sphericity and circularity of each maize hybrid were determined. The experiments were conducted in a completely randomized design with three replicates, using regression analysis of the data. Ozone saturation times remained between 6.6 and 163.9 min, with saturation concentration varying from 0.34 to 1.12 mg L-1. As for the ozone half-life time, the highest value was 10.5 min for the common maize hybrid AG 1051 and the lowest value was 0.14 min for the super sweet maize hybrid GSS 41499. It was concluded that ozone saturation and decomposition kinetics in maize depends on the hybrid contained in the porous medium. Ozone decomposition is faster in porous medium containing super sweet maize hybrids compared with the common maize hybrid.

title: Nutrient and salinity concentrations effects on quality and storability of cherry tomato fruits grown by hydroponic system

description: ABSTRACT This study was conducted to investigate the effects of nutrient and salinity concentrations on the quality of deepflow technique hydroponic system cultivated cherry tomatoes (Lycopersicon esculentum Mill ‘Unicorn’). The conditions were: (1) control (NS-1 × nutrient Solution, Electrical Conductivity – EC: 2.5 mS∙cm–1); (2) 2 × NS (2 × NS-Double NS, EC: 5 mS∙cm–1); (3) NS + 4.23 mM NaCl (NaCl-Sodium Chloride, EC: 5 mS∙cm–1); and (4) NS + 13.70 mM Sea Water – SW (EC: 7.5 mS∙cm–1). NS + 13.70 mM SW treatment showed the lowest fresh weight loss. Visual quality as well as shelf life was the longest in NS (1 × nutrient solution) treated tomato fruits. The longest shelf life at 5 °C, 11 °C, and 24 °C were 21, 16, and 8 days, respectively, in NS (1 × nutrient solution) treated tomato fruits. The highest firmness was recorded in NS (1 × nutrient solution) treated tomato fruits, which was retained after storage. Moreover, NS + 13.70 mM SW treatment increased the cherry tomato fruit’s quality, especially soluble solids and sugar contents. These results indicate that salinity concentration has effect the soluble solids and sugar of cherry tomato fruits. In addition, nutrient concentration influenced the shelf life and firmness of cherry tomato fruits.

title: Intrapopulation recurrent selection by mixed models in papaya of the formosa group

description: Abstract Few cultivars of papaya from the Formosa group are available to producers, and the development of new genotypes is indispensable. Thus, the use of effective selection strategies to obtain more productive cultivars and better quality fruits is also necessary. The aim of this study was to select of half-sib families (HSF) of papaya using the methodology of mixed models. Nineteen HSFs from the Incaper’s papaya breeding program were evaluated in a randomized block design with five replicates and nine plants per plot. The selection was made based on fruit mass (FM), pulp thickness (PT), soluble solids content in pulp (SS) and number of fruits (NF). The genetic parameters and genotypic values were estimated by the REML/BLUP procedure. The selected HSFs increased FM by 26.1%; the PT in 10.5%; the SS in 7.5% and; the NF in 13.0%. The additive heritability within the progenies and the individual variation coefficient obtained indicate that the selection between and within the HSFs can provide greater genetic gains. The selection based on the REML/BLUP methodology was efficient to obtain simultaneous genetic gains for all variables under study despite the negative correlation between them.

title: Safety and Efficacy of Aerobic Exercise Training Associated to Non-Invasive Ventilation in Patients with Acute Heart Failure

description: Abstract Background: Exercise training (ET) improves functional capacity in chronic heart failure (HF). However, ET effects in acute HF are unknown. Objective: To investigate the effects of ET alone or combined with noninvasive ventilation (NIV) compared with standard medical treatment during hospitalization in acute HF patients. Methods: Twenty-nine patients (systolic HF) were randomized into three groups: control (Control - only standard medical treatment); ET with placebo NIV (ET+Sham) and ET+NIV (NIV with 14 and 8 cmH2O of inspiratory and expiratory pressure, respectively). The 6MWT was performed on day 1 and day 10 of hospitalization and the ET was performed on an unloaded cycle ergometer until patients' tolerance limit (20 min or less) for eight consecutive days. For all analyses, statistical significance was set at 5% (p &lt; 0.05). Results: None of the patients in either exercise groups had adverse events or required exercise interruption. The 6MWT distance was greater in ET+NIV (Δ120 ± 72 m) than in ET+Sham (Δ73 ± 26 m) and Control (Δ45 ± 32 m; p &lt; 0.05). Total exercise time was greater (128 ± 10 vs. 92 ± 8 min; p &lt; 0.05) and dyspnea was lower (3 ± 1 vs. 4 ± 1; p &lt; 0.05) in ET+NIV than ET+Sham. The ET+NIV group had a shorter hospital stay (17 ± 10 days) than ET+Sham (23 ± 8 days) and Control (39 ± 15 days) groups (p &lt; 0.05). Total exercise time in ET+Sham and ET+NIV had significant correlation with length of hospital stay (r = -0.75; p = 0.01). Conclusion: Exercise training in acute HF was safe, had no adverse events and, when combined with NIV, improved 6MWT and reduce dyspnea and length of stay.

title: Zinc copper ratio of Japanese quails diets posture

description: ABSTRACT The objective of this study was to verify the effect of the supplementation of different organic zinc and inorganic copper ratios and to compare the results with the Japanese quail control diet on the productive performance and egg quality. Two experiments were carried out in the experimental area of the Federal University of Espírito Santo, varying the levels of organic zinc and maintaining the recommended copper and the other varying levels of inorganic copper. The experimental period was 84 days. Five mineral premixes were used. Performance and egg quality variables were analyzed. It was first observed that the evaluated variables were not affected significantly by the different mineral relations, except for relative and absolute weight of the bark. In the second test, there was no interaction between the zinc and copper levels, neither between the control and the control diet, for any of the variables observed, when analyzing the individual means, a significant difference was observed for posture rate, commercial and total eggs ratio, feed intake, and in the Haugh Unit. It can be concluded that the ratio of 35mg/kg organic zinc and 3,5mg/kg of inorganic copper met the nutritional requirements of the animals for performance and egg quality.

title: Population structure and reproductive biology of Haemulopsis corvinaeformis (Perciformes, Haemulidae) in the south coast of Pernambuco, northeastern Brazil

description: ABSTRACT: Roughneck Grunt (Haemulopsis corvinaeformis Steindachner, 1868) is the second most important species caught as bycatch of the shrimp fishery in Pernambuco, Northeastern Brazil. However, the population dynamic of this species is poorly known in the region. The aim of this study was to describe aspects of the population structure and reproductive biology of the H. corvinaeformis, providing important information for the development of sustainable management practices. Specimens were collected monthly from August 2011 to July 2012 and quarterly from October 2012 to June 2014. A total of 1,140 individuals was collected; 340 males (29.8%), 391 females (34.3%), and 409 were immature and could not be sexed (35.9%). Total length ranged from 7 to 25 cm. In general, total length of females [12.85 ± 2.49 cm (mean± SD)] and males [12.72 ± 2.46 cm (mean ± SD)] were similar (p &gt; 0.05). The proportion of males and females was similar along the year, except in March. The relationship between total length and total weight was statistically significant (p&lt; 0.05), showing an isometric growth. The (GSI) coupled with the distribution of maturational stages suggests that females reproduce all year around, with a peak during October-November. The length at first maturity (L50) was estimated at 11.88 cm for females and 11 cm for males.

title: Trend of adults’ occupational physical activity levels and nutritional status over four decades in Brazil

description: Abstract Objective: to evaluate the trend of adults’ (≥ 20 years) occupational physical activity levels and nutritional status in Brazilian national surveys carried out over four decades. Methods: the declared data regarding main occupation was stratified in three physical activity levels (light, moderate, and heavy) according to the classifications in force when the surveys were conducted. The nutritional status was determined according to the World Health Organization classification based on the body mass index (BMI, kg.m-2) as underweight (BMI &lt; 18.5), normal (18,5 ≤ IMC &lt; 25) and overweight (BMI ≥ 25). All estimates were calculated using the sampling weights from the surveys. Results: the population with declared occupation increased in the period, with greater moderate physical activity levels in the 1970’s and shifting to light in the 2000’s. The prevalence of underweight decreased and of overweight increased substantially for all physical activity levels. Overweight ranged from 27.6 to 49.7% in light levels and from 12.7 to 43.3% in heavy levels. Conclusions: despite the limitations of the study (the physical activity levels were estimated by declared occupation and did not consider the development/modification of labor processes), we concluded that workers in Brazil present a positive energy balance regardless of their occupational physical activity levels.

title: Use of Doppler Ultrasound for Saphenous Vein Mapping to Obtain Grafts for Coronary Artery Bypass Grafting

description: Abstract Introduction: The great saphenous vein is widely used as a graft in coronary artery bypass grafting surgery. Complications due to saphenous vein harvesting can be minimized when using ultrasonography mapping and marking. Objective: To analyze by clinical trial the use of vascular ultrasonography to map the saphenous vein in coronary artery bypass grafting to determine viability and dissection site. Methods: A total of 151 consecutive patients submitted to coronary artery bypass surgery with the use of the great saphenous vein as a graft were selected for this prospective study. They were divided into two groups: Group 1 - 84 patients were submitted to ultrasonographic mapping and marking of the saphenous vein; Group 2 - 67 patients had saphenous vein harvested without any previous study. Both groups were coupled with follow-up on the 1st, 5th and 30th postoperative days. Primary endpoints were need for incision of the contralateral leg and wound complications within 30 days. Results: Both legs had to be incised in 6 (8.95%) patients from Group 2 (P=0.0067). Wound complications occurred in 33 (23.4%) patients within 30 days, 21 (35%) from Group 2 e 12 (14.8%) from Group 1 (OR 3.095, 1.375-6.944, CI 95%, P=0.008). Within 30 days there were 4 (2.8%) deaths, all in Group 2 (P=0.036). Conclusion: The use of vascular ultrasonography for mapping of the great saphenous vein in coronary artery bypass surgery has properly identified and evaluated the saphenous vein, significantly reducing wound complications and unnecessary incisions. It would be advisable to use this noninvasive and easy to use method routinely in coronary artery bypass surgery.

title: Performance, carcass and meat characteristics of two cattle categories finished on pasture during the dry season with supplementation in different forage allowance

description: ABSTRACT The objective this paper was to evaluate the effect of two categories of beef finished in pasture with supplementation with two herbage allowance on performance, carcass and meat characteristics. Thirty-six Guzera cattle were used, 18 steers and 18 heifers with an initial age of 20 months. There was significant difference in daily weight gain for animal category and the herbage allowance, which were higher in males and animals submitted to high herbage allowance. Steers showed higher final weight, carcass weight and forequarter yield compared with the heifers, although the hindquarter yield was higher in the heifers, however the herbage allowance did not influence these characteristics. There were not statistical differences for carcass yield, ribeye area, backfat thickness and marbling score for the animal categories and herbage allowance. The meat chemical composition of the steers did not differ of the heifers, however, the animals submitted to high herbage allowance was increase in ether extract and pH, decrease in protein percentage. It was concluded that the animal category and the herbage allowance changed the animal performance, improving performance in males and cattle submitted to high herbage allowance.
