Importância do destreinamento físico sobre a capacidade funcional em indivíduos...

Resumo Contexto O treinamento físico é uma estratégia bem estabelecida para a reabilitação da capacidade funcional de indivíduos com doença arterial obstrutiva crônica periférica (DAOP). No entanto, após um programa de treinamento físico, alguns indivíduos podem descontinuá-lo, causando destreinamento. A literatura é escassa sobre os efeitos do destreinamento físico em indivíduos com DAOP; portanto, torna-se im...

Infection of expanded polytetrafluoroethylene and Dacron-coated stents with Sta...

Abstract Background Diagnosis of the etiologic agent of endoprosthesis infections is essential to enable treatment, since these infections constitute important complications of endovascular procedures. Sonication of explanted tissue and materials is a technique that can be used to facilitate detection of biofilm-producing bacteria. Objectives To evaluate infection of pigs' aortas after implantation of nitinol s...

Abdominal aortic aneurysm model in swine with bovine pericardium patch

Abstract Background Aneurysm repair using endovascular techniques has grown in importance as materials have improved. Studies of endovascular prostheses require experimental models that reproduce anatomic and pathophysiological characteristics of human aneurysms. Objectives To describe a porcine model of abdominal aortic aneurysm. Methods This prospective cohort study used eleven Large White female pigs with a ...

Efeito de diferentes modalidades de treinamento físico no consumo de oxigênio d...

Resumo O treinamento físico é capaz de aumentar o consumo de oxigênio de pico em indivíduos que sofreram infarto agudo do miocárdio. No entanto, em relação à eficácia de diferentes tipos de intervenções ainda há uma lacuna na literatura. O objetivo do presente estudo foi avaliar os efeitos de diferentes modalidades de treinamento físico no consumo de oxigênio de pico de pacientes pós-infarto agudo do miocárdio....

Thoracic aortic aneurysm. An experimental model in pigs

ABSTRACT Purpose To describe an unpublished experimental model of descending thoracic aortic aneurysm in pigs. Methods Ten Landrace female pigs aged 10 to 12 weeks old and with initial weights from 17 to 25 kg were anesthetized and their descending thoracic aortas exposed by fifth intercostal space left thoracotomy. The thoracic aorta was isolated. A 2-cm wide × 2-cm long patch of ready-made bovine pericardium ...

Histological changes secondary to use of anti-angiogenic therapy after interrup...

Abstract Background Anti-angiogenic regulators may have therapeutic implications for onset and progression of atherosclerosis. Objectives To demonstrate histological changes secondary to the use of bevacizumab in the aorta of pigs after interruption of flow in the vasa vasorum. Methods Twelve pigs were divided into two groups. The intercostal arteries of the descending aorta were dissected and ligated and wrapp...

Hematoma intramural e úlcera penetrante da aorta: incertezas e controvérsias

Resumo A história natural do hematoma intramural (HI) e da úlcera penetrante (UP) é muito variável, já que podem progredir para a formação de aneurisma, ruptura, dissecção, e podem até mesmo regredir, no caso específico do HI. Exames de imagem têm crescente papel no manejo clínico e operatório da UP e do HI. Ao contrário das projeções semelhantes a úlcera, achados de lagos sanguíneos não são relatados nos estud...

Experimental Model of Saccular Abdominal Aortic Aneurysm in Swines with Pericar...

Abstract Objective: To consider modifications in an experimental model of saccular aortic aneurysm, aiming at better reproducibility, to be used in the development of vascular prostheses. Methods: Experimental study in two phases, developed in the Center of Experimental Surgery and Bioterium (CCEB) of the University of Health Sciences of Alagoas (UNCISAL), with 11 hybrid swine, female, mean weight of 20 ± 5 kg,...

Iliac artery myointimal hyperplasia in rabbits submitted to angioplasty and tre...

Objective: to assess post-angioplasty myointimal hyperplasia in iliac artery of rabbits treated with extract of Moringa oleifera leaves. Methods : we conducted a randomized trial in laboratory animals for five weeks of follow-up, developed in the Vivarium of Pharmaceutical Technology Laboratory of the Universidade Federal da Paraíba. We used rabbits from the New Zealand breed, subjected to a hypercholesterolemi...
