Our appreciation of the roles that platelets play in vascular biology is constantly expanding. One of the major roles of platelets is in initiating and accelerating immune responses. Platelet transfusion may be associated with adverse inflammatory outcomes manifested as fever, discomfort, tachycardia, and respiratory issues. This may in part be due to immune mediators either expressed by activa...

BACKGROUND Platelet concentrates may demonstrate visual, macroscopic clumps immediately after collection following aphaeresis or production from whole blood, independently of the preparation method or equipment used. The relationship between the occurrence of clumping and their effect on in vitro quality of platelets was investigated. MATERIAL AND METHODS Platelet concentrates, suspended in S...

BACKGROUND Hemorrhagic shock is a leading cause of death following severe trauma, and platelet transfusions are frequently necessary to achieve hemostasis. Platelets, however, require special storage conditions, and storage time has been associated with loss of platelet quality. We hypothesized that standard storage conditions have a deleterious effect on platelet mitochondrial function and pla...

BACKGROUND AND OBJECTIVES Platelet concentrates (PC) are used in thrombocytopenia and inherited or acquired platelet dysfunction disorders. Thus, retaining the platelets quality and function during storage will lead to desirable outcomes in treatment of such patients.  METHODS  In this study, we evaluated 40 PC bags, prepared by PRP method in IBTO centers. We applied an array of assays, on fi...

Chronic and acute non-healing wounds represent a major public health problem, replacement of cutaneous lesions by the newly regenerated skin is challenging. Platelet-rich plasma (PRP) widely used throughout diverse fields medicine for improving tissue regeneration. The aim this study was to evaluate effectiveness autologous platelet-rich in individuals with chronic wounds. This prospective carr...

The effect of platelet concentrate storage temperature (4 degrees C versus 22 degrees C) on platelet adenine nucleotide metabolism was studied. In general, levels of platelet ATP and ADP, the release reaction, and the metabolis nucleotide pool were best preserved for 72 hr by storage of concentrates at 4 degrees C. Storage of concentrates for 72 hr at 22 degrees C was occasionally associated wi...

Background: Storage of platelet concentrates (PCs) at room temperature (20-24°C) limits its storage time to 5 days due to the destructive effects of platelet storage lesion (PSL) and bacterial contamination. Although prolonged storage of platelets (PLTs) at 4°C reduces the likelihood of bacterial contamination and PSL levels, it is accompanied by an increase in the clearance rate and changes in...
