Abstract The coronavirus disease 2019 (COVID-19) remains serious around the world and causes huge deaths economic losses. Understanding transmission dynamics of diseases providing effective control strategies play important roles in prevention epidemic diseases. In this paper, to investigate effect delays on COVID-19, we propose a delayed SEIR model describe COVID-19 virus transmission, where two indicating incubation recovery periods are introduced. For system, prove its solutions...
Purpose: To explore the clinical value of Electromyography (EMG) and Heart Rate Variability (HRV) in diagnosis early DPN provide basis for diagnosis, treatment, prevention DPN. Methods: 105 patients with type 2 diabetes mellitus (T2DM) Changji People’s Hospital were treated from January 2023 to December 2023. They stratified into DPN-symptomatic (DPN group, n=55) DPN-asymptomatic (NDPN n=50) cohorts based on presence or absence clinically confirmed diabetic peripheral neuropathy. The...
Both macrophages and T cells play a critical role in inflammatory bowel disease (IBD) development. Since our previous studies have shown that novel immune checkpoint molecule erythrocyte membrane-associated protein (ERMAP) affects macrophage polarization negatively regulates cell responses, we investigated the effects of ERMAP on DSS-induced colitis progression mice. C57BL/6 mice developed dextran sodium sulfate (DSS) model, treated with control Fc (Control Ig) ERMAP-Fc fusion (ERMAP-Ig) for...
In this paper, a modified time-lag SEIRD model to describe the dynamic propagation mechanism of COVID-19, adding latency, cure, and death-delayed time lag. The optimality conditions for delayed optimal control problem are derived is analysed verified by numerical simulations. simulation analysis validation provide an effective theoretical basis COVID-19.
