13. Comparação das respostas fisiológicas no teste de exercício cardiopulmonar e em três testes de exercício submáximo em pacientes com doença pulmonar obstrutiva crônica / Comparison of physiological responses to the cardiopulmonary exercise test and to three submaximal exercise tests in patients with chronic obstructive pulmonary disease
INTRODUÇÃO: A doença pulmonar obstrutiva crônica (DPOC) apresenta obstrução crônica ao fluxo aéreo e evolui com perda da capacidade funcional. A intolerância ao exercício é um marcador prognóstico da doença. OBJETIVO: Investigar as respostas fisiológicas no teste incremental com cicloergômetro (TECP), teste do degrau de 6 minutos (TD6), teste

14. STROKE â THE NURSING DIAGNOSES ANALYSIS SHOW IN THE ACTIVITY/EXERCISE BRANCH / ACIDENTE VASCULAR ENCEFÃLICO - ANÃLISE DOS DIAGNÃSTICOS DE ENFERMAGEM DA CLASSE ATIVIDADE/EXERCÃCIO
To determine nursing diagnoses is a very necessary task, for it contributes to the better planning of the interventions in clients who survived after the stroke and who, in most of the cases, presented incapabilities. Due to this, the study aimed to analyze the nursing diagnoses shown in the Activity/Exercise branch in clients with stroke during the period o

15. Effect of exercise training and carvedilol treatment on cardiac function and structure in mice with sympathetic hyperactivity-induced heart failure
The present investigation was undertaken to study the effect of β-blockers and exercise training on cardiac structure and function, respectively, as well as overall functional capacity in a genetic model of sympathetic hyperactivity-induced heart failure in mice (α2A/α2CArKO). α2A/α2CArKO and their wild-type controls were studied for 2 months, from 3 to

16. Efeito do treinamento físico em modelo genético de insuficiência cardíaca induzida por hiperatividade simpática / The Therapeutic effect of exercise training in genetic model of heart failure induced by sympathetic hyperactivity
The sympathetic nervous activity is increased in heart failure (HF) and is associated with the severity and prognosis of disease. Mice lacking both α2A and α2C adrenergic receptors (α2A/α2CARKO) develop sympathetic hyperactivity- induced HF and present 50% mortality rate by seven mo of age. The decreased cardiac contractility, cardiomyocy

17. Avaliação do estado nutricional, tolerância ao exercício e desempenho muscular em pacientes com doença pulmonar obstrutiva crônica.
A doença pulmonar obstrutiva crônica (DPOC) é caracterizada por uma inflamação anormal dos pulmões em resposta à inalação de partículas e/ou gases tóxicos, especialmente a fumaça de cigarro. Tem sido considerada uma doença sistêmica por desencadear diversas manifestações no organismo que incluem a depleção nutricional e a disfunção dos m�

18. Efeito do treinamento físico na cardiomiopatia induzida por hiperatividade simpática em camundongos com ablação dos receptores alpha 2A/alpha 2C- adrenérgicos / Effect of exercise training on cardiomyopathy induced by sympathetic hiperactivity in mice lacking a2A/a2C- adrenoceptors
Presynaptic a2-adrenoceptors (a2 AR) regulate the cardiovascular function by inhibiting neurotransmitter release on the sympathetic nerve terminals. We have recently reported that disruption for both a2A and a2C AR subtypes in mice (KO) leads to sympathetic hyperactivity with evidence of cardiac dysfunction by 4 mo of age. These mice provide a model system f

19. "Pectus excavatum: avaliação comparativa das técnicas operatórias de Robicsek e Nuss" / Pectus excavatum : comparative evaluation of Robicsek and Nuss surgical techniques
Pectus excavatum (PEX) is a depression of the sternum in relation to the costal cartilages. Psychological disorders and exercise intolerance are current clinical abnormalities detectables. Surgical correction of PEX has gained a new momentum since the introduction of the new minimally invasive repair by Nuss. The present study aims to compare the results of

20. Efeito da terapia com Beta-bloqueadores em camundongos com deleção dos receptores alpha 2A/alpha 2C adrenérgicos / Effects of b- adrenergic antagonist therapy in mice lacking a 2A/a 2C adrenergic receptors
We have recently reported that disruption for both a2A ?and a2C adrenergic receptor subtypes in mice (KO) leads to sympathetic hyperactivity with evidence of heart failure (HF) by the age of 7 months. These mice provide a model system for evaluating the efficiency among different ?- adrenergic antagonists (BB) for HF therapy. In the present study, we evaluat

21. Caracterização da participação do sistema renina-angiotensina na cardiomiopatia induzida por hiperatividade simpática / Characterization of renin-angiotensin system in cardiomyopathy induced by sympathetic hyperactivity
We have recently reported that disruption of both alfa2A and alfa2C adrenergic receptor subtypes (KO) in mice leads to sympathetic hyperactivity with evidence of heart failure (HF) by seven months (mo) of age. In the present study, we have performed the phenotypical characterization on KO mice at three and seven month of age. In addition, we evaluated the ef

22. Late Clinical Outcomes of the Fontan Operation in Patients with Tricuspid Atresia
OBJECTIVE: Evaluation of the long-term clinical results of the Fontan operation in patients with tricuspid atresia. METHODS: A retrospective analysis was made at the Instituto de Cardiologia do Rio Grande do Sul (Institute of Cardiology of Rio Grande do Sul), from August 1980 through January 2000, of 25 patients with a long-term follow-up, out of a series of

23. Adaptações cardio-respiratorias ao treinamento fisico aerobio em mulheres na menopausa : estudo longitudinal e transversal
Menopause is a special period in a woman?s life when almost all them experience progressive modification in their physical and psychological sates. Among various symptoms, there are those related to the cardiorespiratory system like: intolerance to exertion, skin hyperemia and heart palpitation. The objective of this research, that included a longitudinal an

24. Cardiorespiratory Response to Exercise after Repair of Tetralogy of Fallot
We studied 24 patients who had a graded exercise test 1 to 16 years after correction of tetralogy of Fallot. Maximal oxygen consumption was subnormal in 19 of the patients. We found no relationship between age at repair, postoperative right ventricular pressure, right ventricular-to-pulmonary artery pressure gradient, or ratio of right ventricular and left v
