13. Echocardiographic evaluation during weaning from mechanical ventilation
INTRODUCTION: Echocardiographic, electrocardiographic and other cardiorespiratory variables can change during weaning from mechanical ventilation. OBJECTIVES: To analyze changes in cardiac function, using Doppler echocardiogram, in critical patients during weaning from mechanical ventilation, using two different weaning methods: pressure support ventilation

14. Relação entre o ciclo sono e vigília e a função cardiorrespiratória em estudantes de medicina
Os estudantes, normalmente, apresentam um padrão de sono irregular caracterizado por atrasos de início e final do sono dos dias de semana para os finais de semana, curta duração de sono nos dias de semana e longa duração de sono nos finais de semana. A redução do sono necessário na semana e a consequente irregularidade no ciclo sono e vigília (CSV)

15. Síntese e caracterização de nanopartículas de TiO2 pelo método do precursor polimérico
Currently, scientific research in the field of nanotechnology has attracted growing interest because of its several applications, either through design of new products, materials characterization, production and application of structures, devices and systems in the form or function are features of the nanoscale. Thus, there is advancement in technology and i

16. Left-ventricular function and cardiorespiratory responses in patients undergoing coronary artery bypass grafting after short-term inpatient cardiac rehabilitation / Função ventricular esquerda e respostas cardiorrespiratórias após reabilitação cardíaca hospitalar em pacientes submetidos à cirurgia de revascularização do miocárdio
It is well-known that cardiac autonomic and pulmonary function are impaired after coronary artery bypass surgery (CABG). Strategies resulting in beneficial cardiorespiratory responses as soon as possible after surgery are clinically important in these patients. However, information on the differences in cardiorespiratory responses of these patients to inpati

17. Caracterização dos quimiorreceptores de O2 envolvidos no controle dos reflexos cardio-respiratórios de trairão, Hoplias lacerdae (Teleostei, Erythrinidae) em resposta à hipóxia ambiental
The ability to sense and respond to oxygen availability in the environment is of extreme functional importance for fish. This is even more so in tropical freshwater habitats where environmental hypoxia can occur rapidly in space and time. Recent physiological studies on the cardio-respiratory response of tropical fishes have focused on hypoxia tolerant speci

18. Effects of sedation during upper gastrointestinal endoscopy on endocrine response and cardiorespiratory function
Upper gastrointestinal endoscopy is often accompanied by tachycardia which is known to be an important pathogenic factor in the development of myocardial ischemia. The pathogenesis of tachycardia is unknown but the condition is thought to be due to the endocrine response to endoscopy. The purpose of the present study was to investigate the effects of sedatio

19. Efeito da terapia estrogênica sobre o controle autonômico da freqüência cardíaca e a capacidade aeróbia de mulheres saudáveis.
The effects of female sex hormones on the cardiovascular system have been the topic of much discussion and controversy in the literature. Nevertheless, many scientists believe that estrogens play an important cardioprotective role in premenopausal women, with their effects being observed directly on blood vessels or indirectly by the promotion of an antiathe

20. Avaliação polissonográfica e de função cardio-respiratória de adolescentes portadores de anemia falciforme clinicamente estáveis
Introduction: sickle cell anemia is the most prevalent hereditary disease in Brazil, occurring in 0,1 to 0,3% of the negro population. The occurrence of 1-3/1000 new annual cases in the country are also estimated, thus characterizing an important public health problem in our environment. Its also know that the prevalence of nocturnal desaturation of hemoglob

21. New auxiliary indicators for the differential diagnosis of functional cardiorespiratory limitation in patients with chronic obstructive pulmonary disease and congestive heart failure
OBJECTIVE: To differentiate the nature of functional cardiorespiratory limitations during exercise in individuals with chronic obstructive pulmonary disease (COPD) or congestive heart failure (CHF) and to determine indicators that may help their classifications. METHODS: The study comprised 40 patients: 23 with COPD and 17 with CHF. All individuals underwent

22. Efeitos da temperatura nas respostas cardio-respiratórias e na respiração aérea acessória de JEJU, Hoplerythrinus unitaeniatus (Erytrinidae) aclimatados a 15, 20, 25 e 30C e submetidos a variações de O2 ambiental.
Peixes de água doce tropical vivem em ambientes de altas temperaturas e baixas concentrações de O2. Isto resultou, ao longo do processo evolutivo, na necessidade da tomada do ar atmosférico em várias espécies de peixes, a fim de compensar seus requerimentos metabólicos, o que requereu modificações anatômicas, fisiológicas e bioquímicas. Estudos s

23. Unexpected longevity in patients with severe kyphoscoliosis.
The threat of premature death in the fourth or fifth decades of life from cardiorespiratory failure in kyphoscoliosis is well known. Ten patients with severe kyphoscoliosis (curves greater than 100 degrees), who had survived into their seventh decade free of cardiorespiratory failure, were encountered over a four-year period. Pulmonary function studies on fi

24. Opioid microinjection into raphe magnus modulates cardiorespiratory function in mice and rats
The raphe magnus (RM) participates in opioid analgesia and contains pain-modulatory neurons with respiration-related discharge. Here, we asked whether RM contributes to respiratory depression, the most prevalent lethal effect of opioids. To investigate whether opioidergic transmission in RM produces respiratory depression, we microinjected a mu-opioid recept
