The formation of stable blood clots or hemostasis is essential to prevent major blood loss and death from excessive bleeding. However, the body's own coagulation process is not able to accomplish timely hemostasis without the assistance of hemostatic agents. For developing novel topical hemostatic agents, tissue adhesives and sealants, it is necessary to understand the coagulation process and the hemostasis mechanism of different materials. Among hemostatic materials, polysaccharides are naturally derived polymers having excellent biodegradable and biocompatible properties. This review provides an overview of polysaccharide-based hemostatic materials and agents, including their advantages and drawbacks in hemostatic applications. Furthermore, polysaccharide-based hemostatic materials with anti-microbial and healing functions are also introduced.

Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

Edible films are significant in prolonging the shelf life of meat products. Herein, we prepared some edible coatings (EW/TNPCSs) based on egg white/chitosan/pectin as polymer matrix, containing tannic acid-nisin composite nano-crosslinker with antibacterial-antioxidant activities. The results of preservation indicated that the prepared EW/TNPCSs reduced the water loss of chilled pork and delayed the changes of taste, texture and surface color.
