BACKGROUND AND OBJECTIVE Platelet-rich plasma is used to deliver growth factors, in a safe and convenient manner, for enhancing bone and periodontal regeneration. However, conflicting reports regarding its effectiveness suggest that further study of the relevant cellular mechanisms is required. The aim of this study was to investigate the in vitro effect of platelet-rich plasma on osteoblasts a...
چکیده مقدمه و هدف: فرایند التیام زخم و رژنریشن شامل آبشاری پیچیده از وقایعی مثل تکثیر سلولی و تمایز است. این مراحل توسط مولکول هایی که فاکتور های رشدی نام دارندکنترل می شوند. فعال سازی پلاکت ها در محل عفونت یا آسیب بافتی منجر به آزادسازی مقادیر قابل ملاحظه ای از مواد بیواکتیو اندوژن شامل فاکتورهای رشدی مانند vegf،pdgf،fgf،egf، tgf? می شود که این عوامل می توانند فرایند ترمیم را تسریع کنند. بنا...
BACKGROUND The effect of platelet-rich plasma on chondrocytes has been studied in cell and tissue culture. Less attention has been given to the effect of platelet-rich plasma on nonchondrocytic cell lineages within synovial joints, such as fibroblast-like synoviocytes, which produce cytokines and matrix metalloproteinases (MMPs) that mediate cartilage catabolism. The purpose of the present stud...
Background: Cancer is the most common cause of death in the world, and it incidence has been increasing for many years in economically developed countries. Early detection of cancers greatly increases the chances for successful treatment. So finding cancers before they start to cause symptoms is a most effective treatment. Recent studies have proposed that blood plasma contains a rich source of...
Antimicrobial Activity of Platelet-Rich Plasma and Platelet-Rich Fibrin Against Streptococcos oralis
BACKGROUND Platelet-rich plasma therapies for tendinopathy appear to provide moderate pain reduction. However, the biological mechanisms behind the observed clinical effects remain poorly characterized. QUESTIONS/PURPOSES The purpose of this study was to explore whether platelet-rich plasma modifies the inflammatory/angiogenic status of already inflamed tenocytes by examining (1) gene express...
Platelet-rich plasma is a current subject of studies on chronic wound healing therapy due to possible pro-angiogenic effects. Microvascular compromise represents the major component in radiogenic wound healing complications. The effects of platelet-rich plasma on irradiated cells of the cutaneous wound healing process are poorly understood so far. In this study, the interaction of endothelial c...
