An Isolated Working Heart System for Large Animal Models
Since its introduction in the late 19(th) century, the Langendorff isolated heart perfusion apparatus, and the subsequent development of the working heart model, have been invaluable tools for studying cardiovascular function and disease(1-15). Although the Langendorff heart preparation can be used for any mammalian heart, most studies involving this apparatus use small animal models (e.g., mou...
متن کاملLarge Mammalian Animal Models of Heart Disease
Due to the biological complexity of the cardiovascular system, the animal model is an urgent pre-clinical need to advance our knowledge of cardiovascular disease and to explore new drugs to repair the damaged heart. Ideally, a model system should be inexpensive, easily manipulated, reproducible, a biological representative of human disease, and ethically sound. Although a larger animal model is...
متن کاملNanomedicine for tuberculosis: Insights from animal models
Patient noncompliance to current tuberculosis (TB) therapy owing to multidrug administration daily leads to treatment failure and emergence of multidrug resistant and extensively drug resistant TB. To avoid the daily dosing, application of nanotechnology is the only viable solution by virtue of sustained release of drugs. Other potential advantages of the system include the possibility of selec...

متن کاملGlutamine cycling in isolated working rat heart.
To what extent does glutamine turnover keep pace with oxidative metabolism in the rat heart? To address this question, the following groups of substrates were presented to the isolated, working rat heart: 1) glucose (5 mM), insulin (40 microU/ml), and [2-13C]acetate (5 mM; high workload, n = 5); 2) pyruvate (2.5 mM) and [2-13C]acetate (5 mM; normal workload, n = 5); or 3) propionate (1 mM) and ...
