OBJECTIVE Because fibrin is transparent and almost invisible by any conventional imaging methodologies, clinical examinations of coronary fibrin thrombus have been ignored, and little is known about its role in the genesis of acute coronary syndrome (ACS). The present study was performed to visualize coronary fibrin thrombus and to examine its role in ACS. METHODS AND RESULTS Dye-staining cor...

Background: Recent improvement in treatments of cancer has significantly increased survival rates of cancer patients. Unfortunately these treatments such as chemotherapy and radiotherapy can sever damage to the ovaries. Ovarian cryopreservation prior to chemo/ radiotherapy and auto-transplantation post-treatment can restore fertility to cancer patients. Hypoxia in the transplant from delayed re...

T HE RELATIONSHIP of platelets and fibrin has interested investigators since the early descriptions of human blood clots.’4 Many studies showed an intimate platelet-fibrin association which indicated that platelets served as centers of clot formation, and as the main support of the fibrin meshwork.5’#{176} Other reports, however, described the relationship to be accidental; that is, platelets a...

INTRODUCTION The healing process after surgery is a challenging issue for surgeons. Various materials and techniques have been developed to facilitate this process and reduce its period. Fibrin adhesives are often used in cardiothoracic and vascular surgery to seal diffuse microvascular bleeding and in general and plastic surgery to seal wound borders. This Case report and literature review wil...

Systematic review of platelet-rich fibrin (PRF) centrifugation protocols in oral and maxillofacial surgery the introduction AR 2 T 3 : an easy to remember acronym correctly report vertical horizontal PRF

Platelet-rich fibrin, developed in France by Choukroun et al., is a second generation platelet concentrate widely used to accelerate soft and hard tissue healing. It is a strictly autologous fibrin matrix containing a large quantity of platelet and leukocyte cytokines. It has also been shown to stimulate the growth of osteoblasts and periodontal ligament cells, both of which are significant for...

Clotting and fibrinolysis are initiated simultaneously in vivo, and fibrinolysis usually occurs without any individualized lysis front (intrinsic fibrinolysis). We have developed a novel model to assess whether morphological changes resulting from intrinsic fibrinolysis are similar to those previously reported at the lysis front using externally applied lytic agents. Fibrin assembly and fibrino...
