Mechanical, biochemical, and morphological changes in the heart from chronic food-restricted rats
(Natl Research Council Canada, 2001-09-01)
Food restriction (FR) has been shown to induce important morphological changes in rat myocardium. However, its influence on myocardial performance is not completely defined. We examined the effects of chronic FR on cardiac ...
Descrição anátomo-topográfica do coração da paca (Agouti paca)
(Universidade Federal do Rio Grande do Sul (UFRGS), 2010-01-01)
Background: The domestic animals heart is a conical hollow viscera, surrounded by pericardium, laterally compressed, accompanying the thorax shape. Atriums constituted the heart basis and their auricles partially bound the ...
Músculo esquelético, insuficiência cardíaca crônica e o papel do exercício
(Universidade Estadual Paulista (Unesp), Instituto de Biociências, 2009-01-01)
Patients with chronic heart failure (CHF) show metabolic, hemodynamic and skeletal muscle alterations, which decrease the life expectancy. These alterations are attributed to several factors. The focus of this review was ...
Dietary restriction: Metabolic shifting for cardiac health
(2003-03-01)
Purpose: To determine the effect of dietary restriction on metabolic pathways and the relationship of the metabolic shifting on antioxidant enzymes in cardiac tissue. Design: Randomized, controlled study. Male rats at 60 ...
Morphologic and biomechanical changes of thoracic and abdominal aorta in a rat model of cigarette smoke exposure
(2013-08-01)
Background: Smoking is the most relevant environmental factor that affects the development of aortic aneurysm. Smokers have elevated levels of elastase activity in the arterial wall, which leads to weakening of the aorta. ...
Effects of tiletamine/zolazepam-romifidine-atropine in ocelots (Leopardus pardalis)
(2004-07-01)
Objectives: To evaluate the effects of a combination of tiletamine-zolazepam-romifidine-atropine in ocelots. Design: Prospective experimental trial. Animals: Eight captive adult ocelots (three females and five males). ...
Aerobic exercise training in heart failure: impact on sympathetic hyperactivity and cardiac and skeletal muscle function
(Assoc Bras Divulg Cientifica, 2011-09-01)
Heart failure is a common endpoint for many forms of cardiovascular disease and a significant cause of morbidity and mortality. Chronic neurohumoral excitation (i.e., sympathetic hyperactivity) has been considered to be a ...
Toxoplasma gondii: Detection by mouse bioassay, histopathology, and polymerase chain reaction in tissues from experimentally infected pigs
(2006-08-01)
In the present study, we evaluated three techniques, mouse bioassay, histopathology, and polymerase chain reaction (PCR) to detect Toxoplasma gondii infection in tissues from experimentally infected pigs. Twelve mixed breed ...
