Identification of Two Main Independent Components of Fibrillating Heart Muscle
Fibrillation is a hazardous phenomenon in cardiac muscle and so any new work towards the understanding of this process is important to the development of new methods in diagnosis and therapy. In this work we have used surface and intra cardiac ECGs of patients with chronic atrial fibrillation (AF). By means of the blind source separation (BSS) algorithm, which is a well-known method in signal p...
متن کاملNative extracellular matrix: a new scaffolding platform for repair of damaged muscle
Effective clinical treatments for volumetric muscle loss resulting from traumatic injury or resection of a large amount of muscle mass are not available to date. Tissue engineering may represent an alternative treatment approach. Decellularization of tissues and whole organs is a recently introduced platform technology for creating scaffolding materials for tissue engineering and regenerative m...
متن کاملA Technique for Seismic Rehabilitation of Damaged Steel Moment Resisting Frames
Moment resisting frames as one of the conventional lateral load resisting systems in buildings suffer from some limitations including code limitations on minimum span-to-depth ratio to ensure the formation of plastic hinges with adequate length at beam ends. According to seismic codes, in ordinary steel moment resisting frames the minimum span-to-depth ratios should be limited to 5 and in speci...
متن کاملAutologous transplantation of bone marrow cells improves damaged heart function.
BACKGROUND Autologous bone marrow cells (BMCs) transplanted into ventricular scar tissue may differentiate into cardiomyocytes and restore myocardial function. This study evaluated cardiomyogenic differentiation of BMCs, their survival in myocardial scar tissue, and the effect of the implanted cells on heart function. METHODS AND RESULTS IN VITRO STUDIES BMCs from adult rats were cultured ...
متن کاملHydroxyl radical generation from heart mitochondria damaged by ischemia.
The hydroxyl radicals are known to be a biologically active oxygen species. A remarkable enhancement of hydroxyl radical generation was observed in the mitochondria obtained from ischemic myocardium. The hydroxyl radicals are the primary reactive species leading to cellular damages, such as membrane damages, DNA damages, enzyme inactivation, protein denaturation and so forth. The origin of the ...
