Background and objectives. Platelet concentrates for surgical use were often tested as surgical adjuvants in the literature, as a source of platelet growth factors to stimulate healing. Many products are often regrouped under the generic and inaccurate term of Platelet-Rich Plasma (PRP). However, what is tested in many studies is usually a combination of platelets and leukocytes (accurately ter...

BACKGROUND Autologous platelet-rich plasma has attracted attention in various medical fields recently, including orthopedic, plastic, and dental surgeries and dermatology for its wound healing ability. Further, it has been used clinically in mesotherapy for skin rejuvenation. OBJECTIVE In this study, the effects of activated platelet-rich plasma (aPRP) and activated platelet-poor plasma (aPPP...

OBJECTIVE Platelet-rich plasma (PRP) has the capacity to improve the bone-healing process. The aim of this pilot study was to investigate the occurrence of bone healing and the time taken to achieve this in patients submitted to medial opening wedge high tibial osteotomy (MOWHTO), comparing platelet-rich plasma with bone marrow aspirate to autologous iliac graft. DESIGN Twenty-five patients w...

Contemporary management of chronic wounds focuses on improving natural healing and individualization of treatment. Incorporating multiple therapies has become increasingly common. Of interest are autologous growth factors, which are especially important in chronic wound healing and may contribute to tissue formation and epithelialization. Autologous platelet concentrate or platelet-rich plasma ...

BACKGROUND Although platelet-rich plasma (PRP) is nowadays a common method in various medical fields, including cosmetic surgery or dermatology, the expensiveness of the kit for processing is still a hurdle. METHODS A new unique economic method for preparing PRP was reported. The method consists in a simple modification of a disposable 5-mL syringe that allows insertion into a common centrifu...

Coagulation factor V (FV), present in plasma and platelets, is indispensable to thrombin formation, yet patients with undetectable plasma FV seldom experience major bleeding. We used thrombin generation assays to explore the role of platelet FV in 4 patients with severe congenital FV deficiency (3 with plasma FV clotting activity [FV:C] < 1%). When triggered with tissue factor (TF) concentratio...

Background: Platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. Platelet concentrates can be prepared by the apheresis method or from the whole blood using the Buffy-coat or Platelet-rich plasma methods. The purpose of this study was to compare four variations of platelet-rich plasma method based on double...
