Hibernating myocardium signal increase which can be visualised with the "late gadolinium enhancement technique". This is probably the most accurate way to visualise scarred myocardium. An alternative (or additional) technique with CMR is the use of low dose dobutamine similar to echocardiography. PET: The finding of a perfusion or metabolic mismatch between PET-FDG and PET-NH is indicative of decreased metabolism. The wall of the affected segments is hypo-, a-, or dyskinetic. The phenomenon is highly significant clinically because it usually manifests itself in the setting of chronic ischemia, that is potentially reversible by revascularisation via cardiac catheterization. The regions of myocardium are
Edmund Alexander Parkes Exercise on the Elimination of Nitrogen". He confirmed independently the observations of Adolf Eugen Fick and Johannes Wislicenus, against Justus Liebig's theory that muscular work implies the destruction of muscular tissue by oxidation. Parkes suggested that the elimination of urea is not dependent on the amount of muscular exercise, but on the consumption of nitrogenous food; and that muscular tissue does not consume itself as a fuel doing work. His experiments on the effects of alcohol on the human body (in which he was assisted by Cyprian Wollowicz) were in three papers (in 1870, 1872, and 1874), on the "Effects
