As meniscal preservation particularly in younger active individuals with a symptomatic meniscal tear remains the preferred treatment option, various methods have been suggested to increase healing and success rates after meniscal repair. The recent increase in clinical use of platelet rich plasma has contributed to the increased use of fibrin clot, which virtually has the same healing property....

IMPORTANCE The combined use of autologous fibrin membrane and the eye platelet-rich plasma (E-PRP) clot could be considered as a new surgical alternative for the closure of corneal perforations. OBJECTIVE To evaluate the use of autologous solid platelet-rich plasma in combination with an autologous fibrin membrane as a surgical alternative for wound closure in perforated corneal ulcers. DES...

Thrombin cleavage of blood coagulation Factor XIII (a2b2) and fibrinogen was studied during in vitro clotting to determine the physiologic sequence of these events. First, the time course of fibrin formation and cleavage of Factor XIII was measured in platelet-rich plasma. Cleavage of fibrinogen was measured by using a radioimmunoassay for fibrinopeptide A. Conversion of trace amounts of radioi...

Periodontal problems have a high prevalence in the general population, these are characterized by loss of attachment, resulting most inferior position free gingival margin, on any part exposed root surface. It may be present both arches, buccal and lingual surfaces, teeth. With advancement techniques advances achieved through technology, with aim optimizing physiological phenomenon healing, add...

We explored the retraction or contraction of platelet-fibrin clots under isometric conditions. In the presence of micromolar calcium clots of normal platelet-rich plasma developed tension at an initial rate of 0.1 to 0.2 g/min per cm2 (initial cross-sectional area). Electron microscopy of clots fixed after attaining a force of 1.6 g/cm2 revealed platelets with elongated bodies and pseudopods in...

Platelet concentrates for surgical use are autogenous regenerative preparations, produced by the centrifugation of the patient own blood sample. Most techniques are often regrouped inappropriately under the historical term of Platelet-Rich Plasma (PRP). Since 15 years, their use dramatically increased in many surgical fields, particularly in oral and maxillofacial surgery. The literature on thi...

Background: Recently, cartilage tissue engineering is the best candidate for regeneration of cartilage defects. We evaluated the potential of fibrin and PLGA/fibrin scaffolds in providing a suitable environment for growth and chondrogenic differentiation of human adipose derived stem cells (hADSCs) in the presence of icariin. Method: The Three-dimensional...
