Myoarchitecture and vasculature of the heart ventricle in some freshwater teleosts
(Blackwell Publishing, 2002-05-01)
The morphological characteristics of the ventricular myocardium and of coronary vascularization were studied in three freshwater teleost species, Piaractus mesopotamicus, Colossoma macropomum and Clarias gariepinus (African ...
Características morfológicas do miocárdio ventricular de Tambaqui (Colossoma macropomun; Characidae, Cuvier, 1818)
(Universidade de São Paulo (USP), Faculdade de Medicina Veterinária e Zootecnia (FMVZ), 2002-01-01)
O Colossoma macropomun, peixe teleósteo com hábito natatório intenso, apresentou ventrículo cardíaco com forma piramidal e miocárdio com estrutura mista, sendo formada por uma camada compacta externa e outra esponjosa ...
Expression and distribution of NOS1 and NOS3 in the myocardium of angiotensin II-infused rats
(Lippincott Williams & WilkinsPhiladelphiaEUA, 2001)
Hypertrophied myocardium is more dependent on extracellular calcium than the normal cardiac muscle
(2010-08-13)
Background: The aim of this study was to analyze stable hypertrophied myocardial function and its response to inotropic maneuvers in rats submitted to renovascular hypertension for a 10-week period (RHT group, n=10). ...
Volume overload influence on hypertrophied myocardium function
(Japan Heart Journal, Second Dept of Internal Med, 2002-11-01)
The aim of this study was to demonstrate that hypertrophied cardiac muscle is more sensitive to volume-overload than normal cardiac muscle. We assessed the mechanical function of isolated left ventricular papillary muscle ...
Heart structure in the Amazonian teleost Arapaima gigas (Osteoglossiformes, Arapaimidae)
(2019-03-01)
The fish heart ventricle has varied morphology and may have a specific morpho-functional design in species adapted to extreme environmental conditions. In general, the Amazonian ichthyofauna undergoes constant variations ...
Upregulation of mRNA myocardium calcium handling in rats submitted to exercise and food restriction
(2011-07-01)
Background: Chronic exercise and food restriction (FR) have directionally opposite changes in transcription of molecular structures of calcium handling and thyroid hormone (TH) status. Objective: Evaluate the association ...
Colchicine attenuates left ventricular hypertrophy but preserves cardiac function of aortic-constricted rats
(Amer Physiological SocBethesdaEUA, 2003)
