Introduction.Amniotic membrane contains a multipotential stem cell population and is expected to possess the machinery to regulate immunological reactions.We investigated the safety and efficacy of allogeneic amniotic membrane-derived mesenchymal stromal cell (AMSC) transplantation in a porcine model of chronic myocardial ischemia as a preclinical
How to reduce the cogging torque of the integrated propeller motor is an important means to improve its noise performance because cogging torque is one of the key factors causing torque ripple.We proposed a method to reduce the cogging torque by optimizing the size of SPOON the Halbach array’s auxiliary pole.First, an analytical model for the
The article considers a chemical variation of accessory and ore-forming chrome spinels from the Kraka ultramafic massif at the different scales, from the deposit to the thin section.A correlation analysis of compositional and structural features of ultramafic rocks and ores was performed.The ultramafic rocks and chromitites in the studied massif sh
