Microfluidics incorporate physiologically relevant substrates and flows that mimic the vasculature and are, therefore, a valuable tool for studying aspects of thrombosis and hemostasis. At high-shear environments simulating arterial flow, a microfluidic assay facilitates the study of platelet function, as platelet-rich thrombi form in a localized stenotic region of a flow channel. Utilizing devices that allow for small sample volume can additionally aid in evaluating platelet function under flow from volume-limited patient samples or animal models. Studying trauma patient samples or samples following platelet product transfusion may aid in directing therapeutic strategies for patient populations in which platelet function is critical. Effects of platelet inhibition via pharmacological agents can also be studied in this model. The objective of this protocol is to establish a microfluidic platform that incorporates physiologic flow, biological surfaces, and relevant hemostatic mechanisms to assess platelet function with implications for the study of trauma induced coagulopathy and transfusion medicine.

At the beginning of 2020, due to the sudden outbreak of COVID-19, education in China was disrupted. The Chinese government has strongly supported online education, while the music education industry has also adopted a "Suspension of class but no suspension of learning " plan. Universities have also carried out online classroom practices, which has also opened a new door to online piano teaching in universities in China. The feasibility of online piano teaching in daily classrooms of universities in China is something worth researching

Purposeof the Review Hemostasis plays a central role in maintaining a normal physiological vasculature, especially during and after vascular injury. Low-density lipoprotein (LDL) receptor-related protein 1 (LRP1) is a transmembrane protein of the LDL family that exhibits multifunctional characteristics that affect endocytosis, signal transduction, and the formation of synthetic cell phenotypes in the vascular wall. Studies have shown that LRP1 is particularly important in various pathways and processes that contribute to the maintenance of vascular homeostasis. Recent Findings LRP1 is pivotal to the pathophysiology of vascular disease that impairs vascular integrity. Recent studies have shown that LRP1 can also act as a coactivator, affecting transcription of other important proteins. Current research uses LRP1-deficient models to specifically study the mechanisms of LRP1 in multiple pathways including vascular cells, helping to guide potential therapeutic targets following vascular injury. Summary This review aims to highlight the broad physiological role that LRP1 plays in vessel integrity, cellular function, and various metabolic and signaling pathways. The review also provides insights into the pathophysiology of vascular diseases, especially those resulting from LRP1 deficiency or dysfunction.
