Thrombotic disorders, such as myocardial infarction, ischemic stroke, peripheral arterial disease, deep venous thrombosis, pulmonary embolism, or other embolic diseases that are responsible for worldwide mortality and morbidity, are manifestations of the formed thrombi by blood clots during a pathologic blood coagulation process. Once thrombi are formed, the only way to resolve the blood clot i...

Morphological and radiological methods were used to study regeneration of the damaged bone of rat mandibles after application of platelet-enriched fibrin clot. A bone hole was artificially created, and in the natural course of regeneration, the hole was immediately filled with blood and there a blood clot formed. After one week of healing, separate islands of young bone tissue appeared. After t...

BACKGROUND Stroke is the second largest cause of death worldwide. Hypercoagulability is a key feature in ischaemic stroke due to the development of an abnormally dense clot structure but techniques assessing the mechanics and quality of clot microstructure have limited clinical use. We have previously validated a new haemorheological technique using three parameters to reflect clot microstructu...

BACKGROUND AND PURPOSE An ability to predict early reperfusion with IV tPA in patients with acute ischemic stroke and intracranial clots can help clinicians decide if additional intra-arterial therapy is needed or not. We explored the association between novel clot characteristics on baseline CTA and early reperfusion with IV tPA in patients with acute ischemic stroke by using classification an...

Objective chemical biomarkers are needed in clinical studies of diet-related diseases to supplement subjective self-reporting methods. We report on several critical experiments for the development of clinically legitimate dietary stable isotope biomarkers within human blood. Our examination of human blood revealed the following: (1) Within blood clot and serum from anonymous individuals (201 ma...

OBJECTIVE : Strands of clot are frequently flushed out of saphenous vein grafts (SVG) during preparation for grafting, particularly those that are endoscopically harvested. However, saline distention at uncontrolled pressures increases graft thrombogenicity and the risk of early failure after coronary artery bypass grafting. The purpose of this prospective investigation was to define the incide...

BACKGROUND This study was designed to evaluate the effect of recombinant human thrombin (rThrombin) concentration on time to hemostasis (TTH), clot durability, and clot strength in settings that replicate the heparinization and platelet inhibition often found in surgical populations. METHODS A modified, anticoagulated rabbit arteriovenous shunt preparation was selected to model vascular anast...

Fibrinogen is a plasma protein that interacts with integrin alphaIIb beta3 to mediate a variety of platelet responses including adhesion, aggregation, and clot retraction. Three sites on fibrinogen have been hypothesized to be critical for these interactions: the Ala-Gly-Asp-Val (AGDV) sequence at the C-terminus of the gamma chain and two Arg-Gly-Asp (RGD) sequences in the Aalpha chain. Recent ...

BACKGROUND AND PURPOSE In the treatment of severe intraventricular hemorrhage (IVH), thrombolytic use and clot size are known to influence clot lysis rates. We evaluated the effect of other variables on IVH clot lysis rates among patients treated with recombinant tissue-type plasminogen activator or placebo. METHODS One hundred patients with IVH and intracerebral hemorrhage volume <30 mL requ...
