ackground: knowing the human platelet antigens (hpa) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. hpa genes frequency in iran is not evaluated, so we investigated the hpa-2, hpa-3, and hpa-5 frequency and their polymorphism. materials and methods: dna from 120 iranians (99 iranian blood donors and 21 patien...

Purpose Herein we evaluated the effects of platelet concentrate (PC) and platelet-poor plasma (PPP) on bone repair using noncritical defects in calvaria rabbits compared them to presence TGF-β1 osteocalcin reparative sites. Methods Five 8.7 mm diameter were created 15 animals. Each defect was treated differently, autograft (ABG), ABG associated with PC (ABG + PC), PPP PPP), isolated PPP, blood ...

Introduction. Oroantral communication (OAC) closure may be accompanied with hard and soft tissue defects. Platelet-rich fibrin (PRF) is the second-generation platelet concentrate that can an effective therapeutic option for of defects up to 5mm. The aim this investigation was evaluate whether PRF could a viable OAC provide sufficient bone quality/quantity forthcoming implant placement. Outlines...

OBJECTIVE Thoracoabdominal aortic aneurysm operations are associated with extensive blood loss and high requirements for allogeneic blood product transfusion. We assessed the efficacy of intraoperative post-cardiopulmonary bypass administration of fibrinogen concentrate in elective thoracoabdominal aortic aneurysm surgery. METHODS In a retrospective group (group A, n = 12) of patients undergo...

BACKGROUND The study of platelet aggregation is essential to assess in vitro platelet function by different platelet activation pathways. OBJECTIVE To assess aggregation and biochemical parameters of random platelet concentrates produced at the Fundação HEMOAM using the quality control tests defined by law. METHODS Whole blood samples from 80 donors and the respective platelet concentrate u...
