In the recent years, the unique characteristics of mesenchymal stem cells (MSCs), consisting their angiogenesis and vascularization activity, as well as anti-inflammatory, anti-ulcer and immunosuppressive features plusdifferentiation capability into multilineage cell, have provided huge favorite among clinicians and researchers that theirs experiments has focused on treatment of different disea...

This study demonstrates that when platelets are stimulated by thrombin in the presence of low concentrations of purified human fibrinogen (10 to 20 micrograms/mL, final concentration) binding of released platelet von Willebrand factor (plt-vWF) to the platelet membrane is enhanced. This effect appears to be mediated by fibrin monomer produced by the action of thrombin on the fibrinogen in the i...

Studies from our laboratory have demonstrated that von Willebrand factor (VWF) stimulates thrombin generation in platelet-rich plasma. The precise role of VWF and fibrin in this reaction, however, remained to be clarified. In the present study we utilized thrombin-free planar fibrin layers and washed platelets to examine the relationship between platelet-fibrin interaction and exposure of coagu...

Background: One of the most significant factors in the success of dental implant procedures, can be mentioned by the quality and quantity of jaw bone. The occurrence of some problems such as trauma, infection, pathological lesions and the long-term absence of teeth in patients, it causes irregularities in the jaw bone and can get bone resorption. Sever defects after trauma or tumor resection ne...

UNLABELLED The purpose of this manuscript was to assess mandibular ramus block grafts used for augmentation of mandibular posterior segments, followed by subsequent implant placement. Twenty-four human subjects in need of lateral ridge mandibular augmentation were included in the current patient series. INCLUSION CRITERIA recipient site had at least 10-mm residual height, but less than 4.3-mm...
