Evaluation of the oxidative profile in leukocytes of jiu jtisu athletes

Oxidative stress is a process where there is an increase in reactive species, both oxygen and nitrogen. This can happen at both systemic and mitochondrial levels. One of the physiological conditions currently associated with oxidative stress is high-performance physical activity. In this way, it is possible to relate that this problem impacts on sports competitions, especially in Jiu-Jitsu, a growing sport in the world and which demands intense physical effort. Thus, the objective was to evaluate the level of mitochondrial and systemic oxidation in leukocytes of jiu-jitsu athletes. 20 adult men were selected for the control group and 13 athletes for the experimental group. A blood collection was performed to perform MTT and chemiluminescence assays for an analysis of mitochondrial and systemic oxidation, respectively. In addition, two reactive nitrogen species were measured: nitric oxide and peroxynitrite. The evaluation of the leukocyte reducing capacity by MTT showed that the athletes presented a greater reducing environment compared to the control. On the other hand, the chemiluminescence evaluation showed that the athletes' leukocytes showed greater systemic oxidation. There was an increase in both reactive nitrogen species in alteta leukocytes. Given this, it was possible to notice that the athletes presented greater systemic oxidative stress, but with mitochondria with better adaptive capacity to the cell's metabolic demands

Yoga for Vital Capacity

The purpose of this study was to ascertain the effect of yogic exercises and pranayam on the vital capacity adolescent school going boys. In total 60 numbers of school students (boys only) were taken as subjects and were divided equally (30 each) into two groups namely Experimental and Control groups. Pre tests on Vital Capacity was conducted prior to Yogic exercises and pranayam treatment to the experimental group and post test was made after a 12 week treatment and comparisons were made between and within the groups using descriptive statistics and Factorial ANOVA. It was concluded that Yoga Training Group (Experimental Group) improves Vital Capacity of adolescent student

Development and bloom in hybrids of wild passion fruit cultivated in different types of pots and shading levels

Ornamental hybrids of passion flowers are thoroughly diffused in many countries and used in the decoration of houses and gardens. However, the cultivation of ornamental passion fruits practically unexploited in Brazil. This study aimed at evaluating the growth and blooming of F1 hybrids of Passiflora L. (P. sublanceolata J.M. MacDougal [ex P. palmeri var. sublanceolata Killip] vs. P. foetida var. foetida L.) cultivated in ceramic and concrete pots under different shading levels. The vegetative and flower evaluations were carried out weekly, in clonal cuttings 60 days after rooting. The height, leaf length and width, the number of internodes and leaves and stem diameter were evaluated using a randomized complete design in a factorial scheme which corresponded to two genotypes, two types of pot, three shading levels (25 %, 50 %, 75 %) and seven weeks of evaluation, with four replications. For the variable number of flowers, the same experimental design was adopted. However, the number of evaluations was modified for three periods, but this was not considered for the flower diameter and leaf area. The shading levels of 25 % and 50 % were the most favorable to the growth in height, whereas hybrid genotypes under 25 % shade had greater increase in the number of leaves, internodes and stem diameter, showing tolerance to moderate shade. The higher values for length, width and leaf area were observed at 75 % shade. The greatest number of flowers was verified at 25 % shadow in concrete pots. As for the types of pot, the ceramic ones were more favorable to the growth of hybrid plants during the first weeks of acclimatization to the treatments, and the concrete ones were more propitious to blooming. Thus, the use of hybrid plants in concrete pots for the ornamentation of internal environments is recommended, if they are well illuminated

Transitions of cardio-metabolic risk factors in the Americas between 1980 and 2014

Describing the prevalence and trends of cardiometabolic risk factors that are associated with non-communicable diseases (NCDs) is crucial for monitoring progress, planning prevention, and providing evidence to support policy efforts. We aimed to analyse the transition in body-mass index (BMI), obesity, blood pressure, raised blood pressure, and diabetes in the Americas, between 1980 and 2014
