Platelets play a major role in the maintenance of endothelial integrity and hemostasis. Exposure of platelets to physical stress such as flow-induced shear stress leads to platelet aggregation, which are accelerated in the presence of exogenous agonists. In this study, we have designed a simple and rapid method for measuring the decrease of blood velocity due to the platelet aggregation and the normalized distance of blood in the microchannel. To evaluate the influence of blood flow on platelet aggregation, ADP and collagen were used as agonists and microfluidic device was made from glass acryl, and double adhesive tape. Our device is expected to be capable of distinguishing the pharmacological effects of various antiplatelet agents under physiological shear rate condition.

The media environment is rapidly evolving to be tailored to viewers using personal mobile devices in accordance with technological evolution and changes in social structures. Broadcast media technology is also advancing to enable new services, including data casting, in various reception environments beyond the existing fixed environment and one-way audio/video content services. In addition, technologies to increase the transmission capacity to accommodate next-generation large-capacity media content as well as communication network utilization and convergence technologies are being developed to facilitate interactive services and expand the broadcasting coverage. We discuss the current status and future prospects in broadcasting technology for terrestrial and mobile communication systems and analyze broadcasting technology elements for upcoming media environments relying on generative artificial intelligence.
