13. Influence of exercise modality on agreement between gas exchange and heart rate variability thresholds
The main purpose of this study was to investigate the level of agreement between the gas exchange threshold (GET) and heart rate variability threshold (HRVT) during maximal cardiopulmonary exercise testing (CPET) using three different exercise modalities. A further aim was to establish whether there was a 1:1 relationship between the percentage heart rate re

14. Activated sludge inhibition capacity index
Toxic compounds in sewage or industrial wastewater may inhibit the biological activity of activated sludge impairing the treatment process. This paper evaluates the Inhibition Capacity Index (ICI) for the assessment of activated sludge in the presence of toxicants. In this study, activated sludge was obtained from industrial treatment plants and was also syn

15. Cardiorespiratory fitness, pulmonary function and C-reactive protein levels in nonsmoking individuals with diabetes
The objective of this study was to evaluate cardiorespiratory fitness and pulmonary function and the relationship with metabolic variables and C-reactive protein (CRP) plasma levels in individuals with diabetes mellitus (DM). Nineteen men with diabetes and 19 age- and gender-matched control subjects were studied. All individuals were given incremental cardio

16. Physical training for asthma
BACKGROUND: People with asthma may show less tolerance to exercise due to worsening asthma symptoms during exercise or other reasons such as deconditioning as a consequence of inactivity. Some may restrict activities as per medical advice or family influence and this might result in reduced physical fitness. Physical training programs aim to improve physical

17. Identification and agreement of first turn point by mathematical analysis applied to heart rate, carbon dioxide output and electromyography
BACKGROUND: The second heart rate (HR) turn point has been extensively studied, however there are few studies determining the first HR turn point. Also, the use of mathematical and statistical models for determining changes in dynamic characteristics of physiological variables during an incremental cardiopulmonary test has been suggested. OBJECTIVES: To

18. COPD patients' oxygen uptake and heart rate on-kinetics at cycle-ergometer: correlation with their predictors of severity
OBJETIVOS: Verificar se há correlação entre a cinética-on do consumo de oxigênio (VO2) e da frequência cardíaca (FC) no teste de carga constante em cicloergômetro (TCC) com o índice BODE e suas variáveis isoladas em pacientes com doença pulmonar obstrutiva crônica (DPOC). MÉTODO: Foram avaliados 14 homens com DPOC de obstrução moderada

19. Variabilidade genética na população brasileira : ancestralidade genômica e fenótipos de capacidade cardiovascular
O processo de miscigenação recente entre diferentes populações ancestrais pode levar a obtenção de resultados espúrios em estudos de associação genética. A estratificação pela classificação de cor de pele é uma ferramenta útil para controle de estrutura populacional, mas, para a população brasileira, alguns estudos demonstraram que este mé

20. Cinética do consumo de oxigênio e da frequência cardíaca, índice BODE e a influência de dois programas de treinamento físico em pacientes com doença pulmonar obstrutiva crônica
A tese constou de três estudos descritos a seguir. O estudo I, intitulado: Cinética-on do consumo de oxigênio (VO2) e da frequência cardíaca (FC) de pacientes com doença pulmonar obstrutiva crônica (DPOC): comparação entre cicloergômetro e equipamento elíptico teve como objetivo avaliar e comparar a cinética do VO2 e da FC em testes de carga cons

21. Cardiopulmonary exercise testing variables as predictors of long-term outcome in thoracic sarcoidosis
Cardiopulmonary exercise testing (CPET) plays an important role in the assessment of functional capacity in patients with interstitial lung disease. The aim of this study was to identify CPET measures that might be helpful in predicting the vital capacity and diffusion capacity outcomes of patients with thoracic sarcoidosis. A longitudinal study was conducte

22. Toxicidade da deltametrina (formulação Butox CE25) nas respostas cardio-respiratórias da tilápia-do-Nilo (Oreochromis niloticus)
Deltamethrin is a synthetic pyrethroid pesticide, type II, considered of low persistence in the environment and widely utilized in agriculture and aquaculture to control plagues and aquatic parasites respectivamently. In spite of it low toxicity in mammals, this pesticide can be extremely toxic for fish. In this study, we evaluate the effects of a sub-lethal

23. ESTIMAÇÃO DA TAXA DE CONSUMO DE OXIGÊNIO EM SISTEMAS DE LODO ATIVADO USANDO FILTRO DE KALMAN E CONTROLE PWM DA CONCENTRAÇÃO DE OXIGÊNIO DISSOLVIDO / ESTIMATION OF THE RATE OF OXYGEN CONSUMPTION IN ACTIVATED SLUDGE SYSTEMS USING KALMAN FILTER AND PWM CONTROL OF THE CONCENTRATION OF DISSOLVED OXYGEN
A medição e a utilização da taxa de consumo de oxigênio (TCO), ou taxa de respiração, é muito importante para os processos biológicos de tratamento de águas residuais. A TCO fornece informações a respeito da atividade biológica e pode indicar a presença de elementos tóxicos capazes de comprometer a unidade de tratamento. Devido à carência de

24. High cell density strategy for poly(3-hydroxybutyrate) production by Cupriavidus necator
Poly(3-hydroxybutyrate) (P(3HB)) is a carbon and intracellular storage source for different microorganisms and its production can achieve high productivities by means of high cell density cultures. The aim of this study was to propose a high cell density strategy for P(3HB) production by Cupriavidus necator. The exponential growth phase demands an accurate c
