1. A Surgical Technique to Preserve the Subvalvular Apparatus in Patients Undergoing Mitral Valve Replacement for Severe Ischemic Regurgitation
ABSTRACT Severe functional mitral valve regurgitation should be treated in patients undergoing myocardial revascularization. When replacement is considered the best therapeutic option, preservation of the mitral subvalvular apparatus is crucial, especially in the emergency setting, because of its primary role in preserving geometry and function of left and r

2. A Mass Causing Right Ventricular Outflow Obstruction - A Dreadful Complication
Abstract The most common cardiac tumour in the pediatric age group is rhabdomyoma. These are usually located in the ventricles, either in the ventricular septum or free wall. Cardiac tumours in early infancy may lead to severely compromised blood flow due to inflow or outflow tract obstruction. The diagnosis of cardiac rhabdomyoma can be established by trans

3. Effects of Physical Training on the Myocardium of Oxariectomized LDLr Knockout Mice: MMP 2/9, Collagen I/III, Inflammation and Oxidative Stress
Resumo Fundamento: O surgimento da doença cardíaca coronariana aumenta com a menopausa, inatividade física e dislipidemia. Sabe-se que o treinamento físico promove a melhora das funções cardiovasculares Objectivo: Investigar os efeitos do treinamento físico aeróbico sobre o ventrículo esquerdo em camundongos LDL knockout ovariectomizadas.

4. Cholesteatoma and hydrocephalus associated to a third ventricle meningioma in a cat
RESUMO: Meningiomas são neoplasias que comumente envolvem o sistema nervoso central de gatos, enquanto colesteatomas são formações nodulares granulomatosas raramente descritas nessa espécie e que resultam de lesões crônicas em plexo coroide. O objetivo desse trabalho é descrever um caso de meningioma em terceiro ventrículo culminando com a formaç�

5. Normal-pressure hydrocephalus: A critical review
RESUMO. A hidrocefalia de pressão normal (HPN) é uma síndrome potencialmente reversível marcada por ventrículos cerebrais alargados (ventriculomegalia), declínio cognitivo, apraxia da marcha e incontinência urinária. Revisar criticamente o conceito, a fisiopatologia, o diagnóstico e o tratamento da HPN idiopática e secundária. Os autores acessaram

6. Smaller left anterior cingulate cortex in non-bipolar relatives of patients with bipolar disorder
Objective: Bipolar disorder (BD) is highly heritable. The present study aimed at identifying brain morphometric features that could represent markers of BD vulnerability in non-bipolar relatives of bipolar patients. Methods: In the present study, structural magnetic resonance imaging brain scans were acquired from a total of 93 subjects, including 31 patie

7. Thyroxine increases Serca2 and Ryr2 gene expression in heart failure rats with euthyroid sick syndrome
ABSTRACT Objective The current study was aimed at analyzing sarcoplasmic reticulum Ca2+ ATPase (Serca2) and ryanodine receptor type 2 (Ryr2) gene expression in rats subjected to surgery that induced HF and were subsequently treated with T4 using physiological doses. Materials and methods HF was induced in 18 male Wistar rats by clipping the ascending tho

8. Development of an experimental model of neurocysticercosis-induced hydrocephalus. Pilot study
ABSTRACT PURPOSE: To develop an experimental model of neurocysticercosis-induced hydrocephalus METHODS: There were used 17 rats. Ten animals were inoculated with Taenia crassiceps cysts into the subarachnoid. Five animals were injected with 0.1ml of 25% kaolin (a standard solution for the development of experimental hydrocephalus) and two animals were inje

9. Prediction of brain atrophy using three drug scores in neuroasymptomatic HIV-infected patients with controlled viremia
ABSTRACTBACKGROUND: Despite potent antiretroviral therapy, HIV still causes brain damage. Better penetration into the CNS and efficient elimination of monocyte/macrophages reservoirs are two main characteristics of an antiretroviral drug that could prevent brain damage. The aim of our study was to assess efficacy of three antiretroviral drug scores to predic

10. Myocardial remodeling and bioelectric changes in tachycardia-induced heart failure in dogs
In this study, electrical and structural remodeling of ventricles was examined in tachycardia-induced heart failure (HF). We studied two groups of weight-matched adult male mongrel dogs: a sham-operated control group (n=5) and a pacing group (n=5) that underwent ventricular pacing at 230 bpm for 3 weeks. Clinical symptoms of congestive HF were observed in bo

11. Improved relationship between left and right ventricular electrical activation after cardiac resynchronization therapy in heart failure patients can be quantified by body surface potential mapping
OBJECTIVES: Few studies have evaluated cardiac electrical activation dynamics after cardiac resynchronization therapy. Although this procedure reduces morbidity and mortality in heart failure patients, many approaches attempting to identify the responders have shown that 30% of patients do not attain clinical or functional improvement. This study sought to

Estudo experimental comparativo entre a derivação cavo-pulmonar associada ao suporte circulatório esquerdo e o suporte circulatório biventricular na falência aguda biventricular / Comparative experimental study between cavopulmonary anastomosis associated with left ventricular assist device support and biventricular circulatory assistance in acute biventricular failure
Background Right ventricular (RV) failure durinq left ventricular assist device (LVAD) support can result in severe hernodynarnic cornpromise with hiqh mortality. Objective: This study investiqated the acute effects of cavopulmonary anastomosis on L VAD performance and riqht ventricular myocardial compromise in comparison with isolated LVAD support and biven
