Syzygium cumini Nectar Supplementation Reduced Biomarkers of Oxidative Stress, Muscle Damage, and Improved Psychological Response in Highly Trained Young Handball Players

The purpose of this study was to investigate the effects of Syzygium cumini (SC) nectar supplementation on performance, markers of oxidative stress, muscle damage, and psychological response in Handball players. Twenty-five young athletes (age = 18.6 ± 2.4 years) from an elite high school national level Brazilian Handball team were randomized into two study groups: SC/Jamelon nectar (SC, n = 12) and placebo (n = 13). The subjects ingested 10 mL/kg/day of Jamelon nectar or placebo 30 min before the training sessions and immediately after training cessation, for 28 days. Body mass index (BMI) and percentage of fat mass were assessed using bioelectrical impedance analysis. Biomarkers of oxidative stress were measured by lipid peroxidation, which was quantified by malondialdehyde (MDA). Total antioxidant capacity (TAC), creatine kinase (CK) activity, and lactate dehydrogenase (LDH) were determined. The 20 m shuttle run test, vertical jump, and running anaerobic sprint test were assessed to verify performance and the fatigue index was calculated. The Profile of Mood States (POMS) questionnaire was used for psychological evaluation. Both groups demonstrated improved vertical jump performance and a decreased fatigue index over time but without significant differences between them regarding performance. There was statistically significance only for SC in CK, LDH, and MDA, and TAC was greater in the SC compared to placebo. Furthermore, only the SC group demonstrated improved mood disturbance and confusion after the intervention. In conclusion, the present study suggests that SC nectar supplementation reduced biomarkers of oxidative stress and muscle damage, and improved psychological response in young handball players

Eletroforese das proteínas plasmáticas em emas (Rhea americana) de diferentes faixas etárias Eletrophoretic plasma protein profile in rhea (Rhea americana) of different age groups

A rheacultura vem crescendo em todo o Brasil. Porém, ainda há uma escassez de informações sobre esta espécie e de médicos veterinários especializados na área. Este trabalho teve como objetivo verificar as diferenças existentes na eletroforese plasmática (gel de agarose) em idades distintas de emas (Rhea americana). Utilizaram-se 45 emas, separadas em quatro grupos: grupo 1 (n=10), animais com 15 dias de idade; grupo 2 (n=10), animais com 30 dias; grupo 3 (n=10), animais com 45 dias e grupo 4 (n=15), animais com 1 ano. Verificou-se homogeneidade nos valores eletroforéticos analisados nas aves dentro de cada faixa etária. Houve diferença entre grupos etários em valores de proteína plasmática total, albumina, globulinas e relação albumina/globulinas. Também houve diferença entre grupos para as frações alfa1, alfa2, ß e gama. Os resultados encontrados demonstram que o perfil eletroforético de emas sofre variações conforme a idade analisada. Dessa forma, exige-se maior atenção por parte do médico veterinário quanto à interpretação desse tipo de exame conforme a idade da ave. Os parâmetros obtidos neste estudo indicam divergência de valores quando comparados com os de outras espécies aviárias, evidenciando a importância de se conhecer tais valores nesta espécie.Breeding of rheas has been growing throughout Brazil. However, there is still lack of information about this species and of professionals specialized in the area. This study was aimed at verifing the differences in plasmatic electrophoresis (agarosis gel) at different ages of rheas (Rhea americana). Fourty-five rheas were separated into 4 groups: group 1: (n=10), 15 day old animals; group 2: (n=10), 30 day old animals; group 3: (n=10), 45 day old animals; group 4: (n=15), 1 year old animals. The electrophoretic values analyzed presented homogeneity within each age group. There were differences between different age groups in the values of total plasmatic protein, albumin, globulins and the albumin/globulin relation. There was also a difference between age groups for fractions alpha1, alpha2, ß and gamma. These results demonstrated that the electrophoretic profile of rheas undergoes variations according to the age analyzed. Therefore, more attention, is needed by the professionals in the interpretation of this type of examination. The parameters obtained from this study show a divergence of values, when compared to from those obtained from other avian species, showing up the importance of understanding these values in this species

Infecção natural por Trypanosoma evansi em cavalos na região Central do Estado do Rio Grande do Sul Natural infection by Trypanosoma evansi in horses in the central area of the state of Rio Grande do Sul, Brazil

O objetivo deste trabalho foi avaliar a causa de mortalidade em cavalos de uma propriedade na região central do Rio Grande do Sul. Amostras de sangue de nove animais foram analisadas utilizando-se a técnica do micro-hematócrito e colorações da capa flogística sendo detectada a presença de Trypanosoma evansi em três amostras. Os sinais clínicos apresentados pelos animais foram anemia, edema das partes ventrais do corpo e incoordenação dos membros posteriores. As técnicas empregadas são de fundamental importância na triagem parasitológica a fim de aumentar as chances de observação dos protozoários.<br>The objective of the research was to evaluate the mortality cause in horses on a farm in the central area of the state of Rio Grande do Sul, Brazil. Blood samples of nine animals were analysed using the microhematocrit technique and stain of buffy coast where in three samples the presence of Trypanosoma evansi was detected. The clinical signs presented by the animals were anemia, edema of the ventral parts of the body and incoordenation of the subsequent members. The techniques used are of fundamental importance in parasitologics selection samples to increase the chances of finding the protozoan
