Denatured muscle grafts can be useful for bridging short radial nerve defects, but the quality of recovery is significantly worse than after nerve graft repair. Even if relatively short nerve defects are bridged with denatured muscle grafts, the outcomes correlate inversely with the length of the gap.
A hybrid numerical method is proposed involving a successful combination of the equivalent electrodes and boundary element method. Electric field and electric potential distribution are determined by using both equivalent electrodes and equivalent charges. Green's function for potential of the charge per unit length, placed in free space, on the boundary of two dielectrics, is used. Magnetic-field distribution is determined by applying equivalent currents through magnetic vector potential and substitution of Ampere's microscopic currents with total currents. The accuracy of the developed method is highlighted with some simple numerical examples.
Metastatic tumors of the heart are rather rare, and rarely clinically symptomatic, and, thus, rarely diagnosed during life. The methods of choice for the diagnosis of the metastasis in the heart are echocardiography, computerized tomography, magnetic resonance imaging, cytological analysis of the pericardial effusion and biopsy. The treatment includes surgery, chemotherapy and radiotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
