Severe acute pancreatitis (SAP) is a critical inflammatory disease with high morbidity and mortality. Current treatments focused on symptomatic relief but failed to prevent inflammation progression in cellular level. In order develop an SAP-targeting drug delivery system alleviate SAP level illustrate its mechanism, we explored the use of proanthocyanidin (PYD) pentoxifylline (PTX) loaded into macrophage membrane-coated self-assembly nanoparticles (FePTX@CM NPs) for targeted treatment. The...
Abstract Pipeline transportation is the best way to send coal slime circulating fluid bed boilers. The pressure loss of in pipeline should be calculated accurately which has close relationship with system design. In this paper, influencing factors pipe flow at high were investigated a designed test facility. experimental results show that directly proportional rate, but inversely diameter. It also found complex exponential volume concentration. Based on above, new calculation model for was...
