Somatotipo, Composição Corporal E Desempenho Em Ultramaratona

This study aimed to characterize somatotype, analyze anthropometric indicators associated with body composition during the race and verify possible relationships with the performance of athletes in a 217-km ultramarathon. For this, ten male volunteers (42.8 ± 3.5 years; 171.4 ± 1.9 cm height, 70.7 ± 3.1 kg body mass; 15 ± 3 years of running exercise) performed a critical velocity (CV) test one week before the competition and were submitted to anthropometric measurements before, at 84 km of the race and at the end of the race. Volunteers finished the race in 46.8 ± 3.4 h (4.9 ± 0.4 km/h; 33.4 ± 1.8% CV). Mean values equivalent to somatotype components accounted for 3.4 ± 0.4 for endomorphy, 5.2 ± 0.4 for mesomorphy and 1.7 ± 0.3 for ectomorphy. Body mass, body mass index, fat-free mass and chest circumference decreased (P <0.05) after 84 and 217 km compared to baseline. Pre-race values of thigh skinfold thickness (R = 0.79) and waist circumference (R = 0.64) were significantly correlated (P <0.05) with final race time. Thus, we concluded that ultramarathoners had mean endo-mesomorph somatotype and reductions in both body mass and fat-free mass during and after the race. Furthermore, the results suggest that increased body fat deposits concentrated in the lower limbs and abdominal region may have a negative impact on the performance of the athletes in 217-km ultramarathon. © 2016, Universidade Federal de Santa Catarina.

Contribution of humic substances from different composts to the synthesis of humin in a tropical soil

The contribution of humic substances of different composts to the synthesis of humin in a tropical soil was evaluated. Increasing doses (0, 13, 26, 52, and 104 Mg ha-1) of five different composts consisting of agroinpowderrial residues were applied to a Red-Yellow Latosol. These composts were chemically characterized and 13C NMR determined and the quantity of the functional alkyl groups of humic acids applied to the soil as compost was estimated. Thirty days after application of the treatments, organic matter samples were collected for fractionation of humic acids (HA), fulvic acids (FA) and humin (HU), from which the ratios HA/FA and (HA + FA)/HU were calculated. The application of the composts based on castor cake resulted in the highest HU levels in the soil; alkyl groups of the HA fraction of the composts were predominant in the organic components added to the HU soil fraction.Avaliou-se a contribuição de substâncias húmicas provenientes de diferentes compostos orgânicos na síntese de humina em um solo tropical. Para isso, foram adicionadas doses crescentes (0, 13, 26, 52 e 104 Mg ha-1) de cinco diferentes compostos orgânicos formulados com resíduos orgânicos agroindustriais em um Latossolo Vermelho-Amarelo. As substâncias húmicas desses compostos foram caracterizadas quimicamente e por ressonância nuclear magnética do 13C, sendo estimados os quantitativos dos grupos funcionais alquil dos ácidos húmicos aplicados no solo via composto. Trinta dias após aplicação dos tratamentos, coletaram-se amostras de solo para fracionamento da matéria orgânica em ácidos húmicos (AH), ácidos fúlvicos (FA) e humina (HU), a partir dos quais foram calculadas as relações AH/FA e (AH + FA)/HU. A aplicação do composto à base de torta de mamona contribuiu para obtenção de teores mais elevados de HU no solo; a incorporação de componentes orgânicos à fração HU do solo foi regida pelo conteúdo de grupos alquil da fração AH dos compostos

Resultados funcionais e sobrevida de pacientes com câncer de cavidade oral e orofaringe submetidos à glossectomia total

Made available in DSpace on 2019-09-11T20:51:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2019Introduction: Cancer of the oral cavity and oropharynx exhibits an aggressive behavior and its diagnosis is, in most cases, attained at advanced stages. Total glossectomy is a therapeutic option in locally advanced cancer, and the only choice in the presence of recurrent or residual disease after chemoradiotherapy. Objective: To evaluate the clinical-epidemiological profile, postoperative complications, survival rates and functional aspects of patients with oral cavity and oropharynx cancer after total glossectomy. Methods: This was a retrospective study that included 22 patients with oral cavity and oropharyngeal cancer after total glossectomy. Results: All patients were males, with a median age of 57 years. Most of tumors were located in the tongue and mouth floor and classified as stage IVa. Total glossectomy as the initial treatment was performed in 18 patients and as a salvage operation in four patients. The major pectoralis myocutaneous flap was used for reconstruction in all cases. The main postoperative complications were wound infections and salivary fistula. Conclusion: Overall survival was 19% and cancer-specific survival was 30.8% in 5 years. Eight patients were rehabilitated for exclusive oral feeding without the dependence on tracheostomy and enteral tube, all with an overall survival greater than 15 months. © 2019 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-FacialQuinsan, I.D.C.M., Universidade de Taubaté (UNITAU), Taubaté, SP, BrazilCosta, G.C., Universidade de Taubaté (UNITAU), Taubaté, SP, BrazilPriante, A.V.M., Universidade de Taubaté (UNITAU), Taubaté, SP, BrazilCardoso, C.A., Universidade de Taubaté (UNITAU), Taubaté, SP, BrazilNunes, C.L.S., Hospital Regional do Vale do Paraíba (HRVP), Taubaté, SP, Brazi

Reversão sexual de rã-touro (Rana catesbeiana) com hormônio masculinizante misturado à ração de girinos Sexual reversion of bullfrog with masculinizing hormone added to the tadpole ration

Este trabalho consistiu em testar a eficiência de um hormônio masculinizante (17beta-hidróxi-17-metil-andróxi-4-en-3-ona) na reversão sexual de girinos de rã-touro (Rana catesbeiana). Foram usados 352 girinos com dois a três meses de idade, nos estádios 30 a 36, para testar quatro níveis de hormônio na ração (0, 30, 60 e 90 mig/g) por 45 dias. Após a metamorfose, 167 imagos foram sacrificados e 185 imagos foram criados até a idade de quatro meses e, então, sacrificados. As análises macroscópicas das gônadas e das características sexuais secundárias confirmaram a masculinização nos tratamentos com hormônio. Muitos ovócitos foram observados nos testículos dos imagos revertidos (ovotestis); entretanto, quatro meses após a metamorfose, os ovotestis ocorreram esporadicamente. Concluiu-se que, após a metamorfose, iniciou-se um processo de reabsorção dos ovócitos nos imagos revertidos, culminando com a quase total reabsorção dos ovócitos no quarto mês de idade.<br>This work consisted in testing the efficiency of a masculinizing hormone (17beta-hydroxy-17-methyl-androxy-4-en-3-one) in the sex reversal of bullfrog tadpoles. Three hundred and fifty two tadpoles with two or three months old, from the stages 30 to 36, were used to test four levels of hormone in the ration (0, 30, 60 and 90 mug/g), for 45 days. After metamorphosis, 167 juveniles were sacrificed and 185 were reared until the fourth month of age and sacrificed thereafter. Macroscopic analysis of the gonads and secondary traits confirmed the masculinization in the treatments with hormone. Many oocytes were observed in the testes of the masculinized juveniles; however, four months after metamorphosis the ovotestes were sporadic. It was concluded that, after metamorphosis, oocyte reabsorption started in reversed juveniles, culminating in almost total reabsorption at the fourth months
