1. Inactivated Pseudomonas aeruginosa inhibits hypoxia-induced pulmonary hypertension by preventing TGF-β1/Smad signaling
Pseudomonas aeruginosa is one of the common colonizing bacteria of the human body and is an opportunistic pathogen frequently associated with respiratory infections. Inactivated P. aeruginosa (IPA) have a variety of biological effects against inflammation and allergy. Transforming growth factor-β (TGF-β) signaling plays a critical role in the regulation of

2. Avaliação experimental do metabolismo energético em dois protocolos de sobrecarga sistólica do ventrículo direito / Experimental evaluation of energy metabolism in two right ventricle systolic overload protocols
Objective: Altered energy metabolism has been identified in myocardial hypertrophy. Some processes are considered beneficial, whereas others are linked to heart failure. The purpose of this study was to compare the activity of three different energy metabolism enzymes in two different protocols of right ventricle (RV) systolic overload in young goats. Method

3. Análise da função ventricular direita em dois protocolos de treinamento com bandagem ajustável do tronco pulmonar / Assessment of right ventricular function in two training protocols with adjustable pulmonary banding
The ideal surgical treatment of transposition of the great arteries is the Jatene operation during the neonatal period. If the neonate remains untreated for several reasons, the left ventricle may become unprepared to sustain systemic circulation. The preparation of the subpulmonary ventricle by pulmonary trunk (PT) banding is an option for the 2-stage Jaten

4. Alterações cardiovasculares de fêmeas de ratos espontaneamente hipertensos (SHR) relacionadas com a idade / Cardiovascular changes in female spontaneously hypertensive rats (SHR) age-related
Hypertension is a major cause of cardiovascular disorders, and the natural progression of this disease may trigger further changes in the circulatory system. Experimental models are widely used in studies on the changes that occur in the cardiovascular system induced by hypertension. The SHR is the model that most closely matches the human hypertension, as i

5. Adaptação oxidativa e funcional progressiva do sistema cardiopulmonar secundária à hipertensão arterial pulmonar em ratos
Pulmonary Arterial Hypertension (PAH) is a disease that affects the pulmonary vessels, essentially pre-capillaries, leading to remodeling of the vascular wall. It is characterized hemodynamic syndrome, which is the increase in pulmonary vascular resistance and right ventricular afterload. A growing body of evidence shows the involvement of oxidative stress i

6. A influência do estrogênio na hipertensão arterial pulmonar : papel do estresse oxidativo
A hipertensão arterial pulmonar é uma síndrome caracterizada por vasoconstrição e remodelamento vascular pulmonar, levando a um aumento progressivo na resistência vascular pulmonar, que eleva a pós-carga imposta ao ventrículo direito, gerando consequente hipertrofia e insuficiência cardíaca direita. Essa doença acomete duas vezes mais mulheres do

7. Disfunção ventricular no pós-operatório da intervenção cirúrgica para correção dos defeitos congênitos da Tetralogia de Fallot: estudo de correção clínica e anatomopatológica / Ventricular dysfunction after the surgical repair of Fallot´s tetralogy: a clinical and anatomopathological study
It was investigate prospectively the histopathological myocardial remodeling in children submitted to surgical repair of Fallots tetralogy, in order to detect possible factors associated to postoperative (PO) echocardiographic findings of systolic or diastolic ventricular dysfunction. Patients and Methods: 23 consecutive Fallot patients (14 males), aged 12 t

8. Avaliação dos mecanismos adaptativos do miocárdio durante sobrecarga de pressão induzida com o uso de bandagem do tronco pulmonar: participação da proliferação celular / Assessment of myocardial adaptive mechanisms during pressure overload induced by pulmonary artery banding: contribution of cell proliferation
INTRODUCTION: Rapid ventricular conditioning induced by pulmonary artery banding (PAB) has been indicated to those patients with transposition of the great arteries (TGA) who have lost the chance for arterial switch operation ? Jatene?s procedure ? aiming at induce myocardial mass increase. However, with time, hypertrophied chamber may exhibit contractile dy

9. Avaliação da Cardioproteção em Ratos que Superexpressam uma Proteína de Fusão Produtora de Angiotensina-(1-7) [TGR(A1-7)3292]
Angiotensin-(1-7) (Ang-(1-7) is now considered to be a biologically active member of the renin-angiotensin system. The functions of Ang-(1-7) are often opposite to those attributed to the main effector component of the renin-angiotensin system, Ang II. Recently it has been suggested that Ang-(1-7) has cardioprotective properties. In the present study, we inv

10. Bandagem ajustável do tronco pulmonar: comparação de dois métodos de hipertrofia aguda do ventrículo sub-pulmonar / Adjustable pulmonary trunk banding: comparison of two methods of acute subpulmonary ventricle hypertrophy
O preparo do ventrículo sub-pulmonar através da bandagem do tronco pulmonar (TP) pode ser aplicado nos pacientes portadores de transposição das grandes artérias (TGA) que perderam a chance da cirurgia no período neonatal ou naqueles já submetidos à correção no plano atrial (Senning ou Mustard) e ainda nos portadores de transposição corrigida das

11. Efeitos do losartan e espironolactona sobre a estrutura e função do coração de ratos espontaneamente hipertensos
Background: The clinical syndrome of heart failure is the final pathway for myriad diseases that affect the heart, mainly ischemic heart disease and hypertension. Left ventricular hypertrophy is accompanied by a structural remodeling that includes myocyte hypertrophy and interstitial fibrosis. These structural abnormalities related to fibrosis lead to increa
