Abstract:
Human platelets play important roles in several physiologic and pathologic processes. Any defects in platelet number and function can lead to a variety of bleeding complications; platelet transfusions are commonly used to improve platelet count and hemostatic function in these cases. However, transfusions are complicated by the short storage life of donated platelets and contamination risks. Synthetic platelet substitutes can render efficient hemostasis while allowing advantages of large-scale preparation, minimum contamination risk via effective sterilization, longer shelf-life, no need for blood type matching, and reduced risks of biologic or pathologic side effects. Recent efforts in synthetic platelet design have additionally focused on applications including hemostasis, drug delivery, and targeted delivery of cancer therapeutics. In the present review, we summarize the advancement of platelet-inspired nanomedicine for artificial blood component, tumor research, and treatment of thrombi.

01:30Mechanism of Breathing I: Inspiration
The respiratory system, an essential network for breathing, comprises the conducting and respiratory zones, each playing a crucial role in the overall process of respiration. Let us explore the detailed mechanism of inspiration, or inhalation, which is the first phase of the respiratory cycle.
Pathway of Air during Inspiration
During inspiration, air enters our body through the nose or mouth and moves through the conducting zone,...
02:22Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.
01:18Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
01:22Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
