13. Estimating of anaerobic metabolisms for maximal accumulated oxygen deficit / Estimativa dos metabolismos anaeróbios no déficit máximo acumulado de oxigênio
O objetivo desse estudo foi averiguar a possibilidade de se estimar os componentes anaeróbios do déficit máximo acumulado de oxigênio (MAOD) utilizando apenas o consumo de oxigênio (VO2). Adicionalmente, foi proposto um método alternativo que não necessita utilizar a extrapolação do VO2 do exercício submáximo para estimar a demanda de O2 para o ex

14. Effect of the caffeine ingestion on the maximum accumulated deficit of oxygen, electromyographic signs of the superficial quadrideps muscles and performance in cyclists / Efeito da ingestão de cafeina sobre o deficit acumulado de oxigenio, sinal eletromiografico dos musculos superficiais do quadriceps e desempenho fisico de ciclistas
O propósito do presente estudo foi investigar o efeitos da ingestão de cafeína (6 mg.kg-1) sobre o desempenho físico e mecanismos associados à fadiga de ciclistas em esforços supramáximos. Fizeram parte do estudo dez ciclistas com idade média de 27,5 ± 4,1 anos e tempo médio de prática na modalidade de 9,8 ± 4,7 anos. Os indivíduos foram submeti

15. Identifying water stress-response mechanisms in citrus by in silico transcriptome analysis
Water deficit is one of the most critical environmental stresses to which plants are submitted during their life cycle. The evolutionary and economic performance of the plant is affected directly by reducing its survival in the natural environment and its productivity in agriculture. Plants respond to water stress with biochemical and physiological modificat

19. Avaliação do uso de ácido salicílico em sementes de calêndula (Calendula officinalis L.) sob diferentes estresses / Study the use salicylic acid of marigold seeds (Calendula officinalis L.) or stressing conditions.
Marigold (Calendula officinalis L.) is an important medicinal and decorative plant also used in the kitchens and in the manufacturing of cosmetic and phytotherapic products. Plants are susceptible to biotical and non biotical aggression and independently of not showing agile movements as defence; they could present deep modifications in the cell metabolism a

21. Spirometric values in children and adolescents with short stature
BACKGROUND: Several factors influence the pulmonary function values considered normal. In children of short stature, there are difficulties in interpreting the pulmonary function. OBJECTIVE: To assess spirometric values in children and adolescents with short stature and to identify a correction factor to adequately predict the expected values for this popula

22. Inibição da sintese de oxido nitrico em ratos wistar : efeitos sobre a morfologia e a função cardiacas
This thesis examines the effects of acute and chronic inhibition of nitric oxide (NO) biosynthesis on cardiac function and morphology in Wistar rats. The contribution of angiotensin 11 to the cardiac changes observed following chronic NO inhibition was evaluated by treating the animais with enalapril, an angiotension converting enzyme inhibitor. Chronic inhi

23. Alterations in the oxygen deficit-oxygen debt relationships with beta-adrenergic receptor blockade in man.
The effects of beta-adrenergic receptor blockade (100 mg oral metoprolol) or matched placebo on gas exchange kinetics were studied in six males. Ventilation and gas exchange were monitored in four transitions for each treatment from loadless pedalling (0 W) to a selected work rate (100 W) and back to 0 W. Breath-by-breath data were averaged for analysis. Oxy

24. Oxygen uptake kinetics during low intensity exercise: relevance for rate adaptive pacemaker programming.
OBJECTIVE: To establish a normal database for oxygen uptake (VO2) kinetics during low intensity treadmill exercise (LITE) testing, to be used as a guideline for programming rate adaptive pacemakers, and to determine its relation to VO2 at anaerobic threshold and peak exercise. DESIGN: VO2 kinetics during LITE were compared with VO2 at anaerobic threshold and
