Study design and methods: A Medline search with keywords ‘platelet rich plasma dental’ further filtered using Boolean operators (AND, Or, NOt) and combination of specific keywords as follows: ‘platelet rich fibrin’, ‘platelet rich plasma regenerative’, ‘platelet rich plasma periodontal’, ‘platelet rich plasma extraction’ with a custom range of 10 years was performed, which yielded 88 results ou...

Platelet-rich plasma (PRP) has gained growing popularity in the treatment of articular cartilage lesions in the last decade. However, the potential harmful effects of leukocytes in PRP on cartilage regeneration have seldom been studied in vitro, and not at all in vivo yet. The objective of the present study is to compare the effects of leukocyte- and platelet-rich plasma (L-PRP) and pure platel...

background: plasminogen is one of the compounds derived from human plasma. activation of plasminogen produces plasmin. plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. the aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine sepharose. materials and methods: normal human plasma was used as the start...

this article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (mtx) in plasma. samples were collocted from children receiving high-dose mtx at shafa hospital (ahvaz university of medical sciences, ahvaz, iran) at various times after the end of eachinfusion. plasma was deproteinized with trichloroacetic acid and the supernatant was i...

a rapid, simple and sensitive high-performance liquid chromatography method was developed for determination of ciprofloxacin in plasma by means of ultraviolet detection. ofloxacin was used as an internal standard and separation carried on a novapak c18 column using a mobile phase of 0.01 m phosphate buffer (ph =2.6): methanol (82: 18 v/v). extraction of drug was performed from plasma by liquid-...

Platelet-rich plasma has been used to treat articular cartilage defects, with the expectations of anabolic and anti-inflammatory effects. However, its role on cellular chondrogenic or fibrogenic commitment is still a controversy. Herein, the role of platelet-rich plasma releasate, the product obtained following platelet-rich plasma activation, on cellular commitment toward the chondrogenic line...

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...

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...
