To solve the problem of the weak starting torque of the permanent magnet synchronous motor (PMSM), a new fast start-up control method based on the principle of the incremental photoelectric encoder and space vector control method is proposed. Exerting the voltage source to the stator in a special position and maintaining the relative angle between the position and the rotor as a constant can solve...
Overproduction of circulating S100A8/A9 occurs in patients following acute myocardial infarction (AMI). It remains unclear whether ischemia insult per se induces S100A8 and S100A9 expression in cardiac myocytes or even whether the cardiac myocytes participate as a source of these proteins. In this study, western blot analysis and quantitative real-time reverse transcription polymerase chain reaction...
Interleukin-1β (IL-1β) is a multifunctional proinflammatory cytokine upregulated in acute phase of heart ischemic disease. Controversial effects of IL-1β have been demonstrated on endothelial progenitor cells (EPCs) functional activity. The aim of this study was to investigate the in vitro effect of IL-1β on activity of human origin EPCs and the possible mechanism involved. EPCs were isolated from...
