A metallocarboxypeptidase that removes C-terminal lysine and arginine from biologically active peptides and proteins thereby regulating their activity. It is a zinc enzyme with no preference shown for lysine over arginine. Pro-carboxypeptidase U in human plasma is activated by thrombin or plasmin during clotting to form the unstable carboxypeptidase U.
Tissue Plasminogen Activator
A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to FIBRINOLYSIN. It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.
A member of the serpin superfamily found in plasma that inhibits the lysis of fibrin clots which are induced by plasminogen activator. It is a glycoprotein, molecular weight approximately 70,000 that migrates in the alpha 2 region in immunoelectrophoresis. It is the principal plasmin inactivator in blood, rapidly forming a very stable complex with plasmin.
Plasminogen Activator Inhibitor 1
A product of the lysis of plasminogen (profibrinolysin) by PLASMINOGEN activators. It is composed of two polypeptide chains, light (B) and heavy (A), with a molecular weight of 75,000. It is the major proteolytic enzyme involved in blood clot retraction or the lysis of fibrin and quickly inactivated by antiplasmins.
Fibrin Fibrinogen Degradation Products
Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
Urokinase-Type Plasminogen Activator
Blood Coagulation Disorders
Blood Coagulation Factors
Disseminated Intravascular Coagulation
Double-layered inflatable suits which, when inflated, exert pressure on the lower part of the wearer's body. The suits are used to improve or stabilize the circulatory state, i.e., to prevent hypotension, control hemorrhage, and regulate blood pressure. The suits are also used by pilots under positive acceleration.
A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
Stable blood coagulation factor activated by contact with the subendothelial surface of an injured vessel. Along with prekallikrein, it serves as the contact factor that initiates the intrinsic pathway of blood coagulation. Kallikrein activates factor XII to XIIa. Deficiency of factor XII, also called the Hageman trait, leads to increased incidence of thromboembolic disease. Mutations in the gene for factor XII that appear to increase factor XII amidolytic activity are associated with HEREDITARY ANGIOEDEMA TYPE III.
Partial Thromboplastin Time
The time required for the appearance of FIBRIN strands following the mixing of PLASMA with phospholipid platelet substitute (e.g., crude cephalins, soybean phosphatides). It is a test of the intrinsic pathway (factors VIII, IX, XI, and XII) and the common pathway (fibrinogen, prothrombin, factors V and X) of BLOOD COAGULATION. It is used as a screening test and to monitor HEPARIN therapy.
A member of the annexin family that is a substrate for a tyrosine kinase, ONCOGENE PROTEIN PP60(V-SRC). Annexin A2 occurs as a 36-KDa monomer and in a 90-KDa complex containing two subunits of annexin A2 and two subunits of S100 FAMILY PROTEIN P11. The monomeric form of annexin A2 was formerly referred to as calpactin I heavy chain.
Clotting time of PLASMA mixed with a THROMBIN solution. It is a measure of the conversion of FIBRINOGEN to FIBRIN, which is prolonged by AFIBRINOGENEMIA, abnormal fibrinogen, or the presence of inhibitory substances, e.g., fibrin-fibrinogen degradation products, or HEPARIN. BATROXOBIN, a thrombin-like enzyme unaffected by the presence of heparin, may be used in place of thrombin.
Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing MYOCARDIAL REPERFUSION INJURY.
Hereditary Angioedema Types I and II
Forms of hereditary angioedema that occur due to mutations in the gene for COMPLEMENT C1 INHIBITOR PROTEIN. Type I hereditary angioedema is associated with reduced serum levels of complement C1 inhibitor protein. Type II hereditary angioedema is associated with the production of a non-functional complement C1 inhibitor protein.
A lipoprotein that resembles the LOW-DENSITY LIPOPROTEINS but with an extra protein moiety, APOPROTEIN (A) also known as APOLIPOPROTEIN (A), linked to APOLIPOPROTEIN B-100 on the LDL by one or two disulfide bonds. High plasma level of lipoprotein (a) is associated with increased risk of atherosclerotic cardiovascular disease.
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
A single-chain polypeptide derived from bovine tissues consisting of 58 amino-acid residues. It is an inhibitor of proteolytic enzymes including CHYMOTRYPSIN; KALLIKREIN; PLASMIN; and TRYPSIN. It is used in the treatment of HEMORRHAGE associated with raised plasma concentrations of plasmin. It is also used to reduce blood loss and transfusion requirements in patients at high risk of major blood loss during and following open heart surgery with EXTRACORPOREAL CIRCULATION.

von Willebrand Factor
A high-molecular-weight plasma protein, produced by endothelial cells and megakaryocytes, that is part of the factor VIII/von Willebrand factor complex. The von Willebrand factor has receptors for collagen, platelets, and ristocetin activity as well as the immunologically distinct antigenic determinants. It functions in adhesion of platelets to collagen and hemostatic plug formation. The prolonged bleeding time in VON WILLEBRAND DISEASES is due to the deficiency of this factor.
Coagulation and fibrinolysis in intact hydatidiform molar pregnancy. (1/1717)Tests of coagulation, fibrinolysis, and platelet function were performed in 17 patients with intact molar pregnancies. Women with intact molar pregnancies had higher fibrinogen factor VIII, and fibrinogen degradation products, concentrations and lower prothrombin, factor X, plasminogen, and plasminogen activator concentrations than controls with normal pregnancies. They also had reduced platelet counts and thromboelastographic values, which indicated hypocoagulability. These results suggest that intravascular coagulation occurs in intact hydatidiform molar pregnancies. (+info)
Isolation of SMTP-3, 4, 5 and -6, novel analogs of staplabin, and their effects on plasminogen activation and fibrinolysis. (2/1717)Four novel triprenyl phenol metabolites, designated SMTP-3, -4, -5, and -6, have been isolated from cultures of Stachybotrys microspora IFO 30018 by solvent extraction and successive chromatographic fractionation using silica gel and silica ODS columns. A combination of spectroscopic analyses showed that SMTP-3, -4, -5, and -6 are staplabin analogs, containing a serine, a phenylalanine, a leucine or a tryptophan moiety in respective molecules in place of the N-carboxybutyl portion of the staplabin molecule. SMTP-4, -5, and -6 were active at 0.15 to 0.3 mM in enhancing urokinase-catalyzed plasminogen activation and plasminogen binding to fibrin, as well as plasminogen- and urokinase-mediated fibrinolysis. On the other hand, the concentration of staplabin required to exert such effects was 0.4 to 0.6 mM, and SMTP-3 was inactive at concentrations up to 0.45 mM. (+info)
Regulation of the activities of thrombin and plasmin by cholesterol sulfate as a physiological inhibitor in human plasma. (3/1717)Thrombin and plasmin, both of which are serine proteases in the plasma of vertebrates, play essential roles in blood clotting and fibrinolysis, respectively, and regulation of their activities is important to suppress the excessive reactions within the vascular network and to prevent tissue injury. Along with the peptidic inhibitors belonging to the serpin family, we found that cholesterol sulfate (CS), which is present at the concentration of 2.0+/-1.2 nmol/ml in human plasma, was a potent inhibitor of both plasma thrombin and plasmin. Thrombin, as determined both using a chromogenic substrate and the natural substrate, fibrinogen, was inactivated upon reaction with CS in a dose-dependent manner, but not in the presence of the structurally related steroid sulfates, I3SO3-GalCer and II3NAalpha-LacCer, suggesting that both the sulfate group and the hydrophobic side chain of CS are necessary for the inhibitory activity of CS. Preincubation of thrombin with CS at 37 degrees C for 10 min was required to achieve maximum inhibition, and virtually complete inhibition was achieved at a molar ratio of CS to thrombin of 18:1. CS-treated thrombin had the same Km and a lower Vmax than the original enzyme, and a higher molecular weight. The molecular weight and activity of the original enzyme were not observed on the attempted separation of the CS-treated enzyme by gel permeation chromatography and native PAGE, indicating that the inactivation of thrombin by CS is irreversible. In contrast, CS was readily liberated from the enzyme by SDS-PAGE, suggesting that hydrophobic interactions are involved in the CS-mediated inactivation of thrombin. When acidic lipids were reacted with thrombin after dissolving them in DMSO, I3SO3-GalCer, steroid sulfates and II3NAalpha-LacCer, as well as CS, but not SDS and sodium taurocholate, exhibited inhibitory activity, probably due to micellar formation facilitating interaction between thrombin and negatively charged lipids. On the other hand, plasmin, as determined using a chromogenic substrate, was more susceptible to acidic lipids than thrombin. CS, I3SO3-GalCer and II3NAalpha-LacCer, all of which are present in serum, inhibited the activity of plasmin in aqueous media, as well as in DMSO-mediated lipid solutions. Thus, acidic lipids in plasma were demonstrated to possess regulatory activity as endogenous detergents toward both enzymes for blood clotting and fibrinolysis. (+info)
Distinct contributions of residue 192 to the specificity of coagulation and fibrinolytic serine proteases. (4/1717)Archetypal members of the chymotrypsin family of serine proteases, such as trypsin, chymotrypsin, and elastase, exhibit relatively broad substrate specificity. However, the successful development of efficient proteolytic cascades, such as the blood coagulation and fibrinolytic systems, required the evolution of proteases that displayed restricted specificity. Tissue-type plasminogen activator (t-PA), for example, possesses exquisitely stringent substrate specificity, and the molecular basis of this important biochemical property of t-PA remains obscure. Previous investigations of related serine proteases, which participate in the blood coagulation cascade, have focused attention on the residue that occupies position 192 (chymotrypsin numbering system), which plays a pivotal role in determining both the inhibitor and substrate specificity of these enzymes. Consequently, we created and characterized the kinetic properties of new variants of t-PA that contained point mutations at position 192. These studies demonstrated that, unlike in coagulation serine proteases, Gln-192 does not contribute significantly to the substrate or inhibitor specificity of t-PA in physiologically relevant reactions. Replacement of Gln-192 with a glutamic acid residue did, however, decrease the catalytic efficiency of mature, two-chain t-PA toward plasminogen in the absence of a fibrin co-factor. (+info)
Age-related changes in blood coagulation and fibrinolysis in mice fed on a high-cholesterol diet. (5/1717)To investigate the pathogenesis of hyperlipidemia-induced atherosclerosis, we examined age-dependent changes in platelet activity, blood coagulation and fibrinolysis in susceptibility to a high cholesterol diet (HCD) feeding in male ICR mice. Pretreatment of platelet-rich-plasma from HCD feeding mice for 3 days with epinephrine (300 microM) resulted in a marked enhancement of adenosine 5'-diphosphate (ADP: 0.1 microM) or collagen (0.7 microgram/ml)-stimulated aggregation compared with the same in control mice. Yohimbine as alpha 2-adrenergic blocker antagonized these aggregations in a dose-dependent manner. A significant increase in plasma total cholesterol and VLDL (very low-density lipoprotein)-LDL (low-density lipoprotein)-cholesterol and the liver/body weight ratio was observed in mice fed on HCD for 3 months (3-month HCD mice). In the early phase of this experiment, a significant increase in fibrinogen was observed. In the middle phase, increases in the activity of antithrombin III (ATIII) and alpha 2-plasmin inhibitor (alpha 2-Pl) followed. Plasminogen content gradually decreased in both normal diet and HCD mice throughout the experiment. The activity of plasminogen activator inhibitor (PAI) decreased in 3-month HCD mice. Morphological observation of the aortic arch from 3-month HCD mice revealed apparent atheromatous plaques not seen in control mice. These results suggest that 3-month HCD mice can be a convenient hyperlipidemia-induced atherosclerotic model and the changes in platelet activity, coagulation and fibrinolysis in the early phase may be a cause of pathologic changes in this model.

Fibrinolytic activation markers predict myocardial infarction in the elderly. The Cardiovascular Health Study. (6/1717)Coagulation factor levels predict arterial thrombosis in epidemiological studies, but studies of older persons are needed. We studied 3 plasma antigenic markers of fibrinolysis, viz, plasminogen activator inhibitor-1 (PAI-1), fibrin fragment D-dimer, and plasmin-antiplasmin complex (PAP) for the prediction of arterial thrombosis in healthy elderly persons over age 65. The study was a nested case-control study in the Cardiovascular Health Study cohort of 5201 men and women >/=65 years of age who were enrolled from 1989 to 1990. Cases were 146 participants without baseline clinical vascular disease who developed myocardial infarction, angina, or coronary death during a follow-up of 2.4 years. Controls remained free of cardiovascular events and were matched 1:1 to cases with respect to sex, duration of follow-up, and baseline subclinical vascular disease status. With increasing quartile of D-dimer and PAP levels but not of PAI-1, there was an independent increased risk of myocardial infarction or coronary death, but not of angina. The relative risk for D-dimer above versus below the median value (>/=120 microg/L) was 2.5 (95% confidence interval, 1.1 to 5.9) and for PAP above the median (>/=5.25 nmol/L), 3.1 (1.3 to 7.7). Risks were independent of C-reactive protein and fibrinogen concentrations. There were no differences in risk by sex or presence of baseline subclinical disease. D-dimer and PAP, but not PAI-1, predicted future myocardial infarction in men and women over age 65. Relationships were independent of other risk factors, including inflammation markers. Results indicate a major role for these markers in identifying a high risk of arterial disease in this age group. (+info)
Relationship of plasmin generation to cardiovascular disease risk factors in elderly men and women. (7/1717)Plasmin-alpha2-antiplasmin complex (PAP) marks plasmin generation and fibrinolytic balance. We recently observed that elevated levels of PAP predict acute myocardial infarction in the elderly, yet little is known about the correlates of PAP. We measured PAP in 800 elderly subjects who were free of clinical cardiovascular disease in 2 cohort studies: the Cardiovascular Health Study and the Honolulu Heart Program. Median PAP levels did not differ between the Cardiovascular Health Study (6.05+/-1.46 nmol/L) and the Honolulu Heart Program (6.11+/-1.44 nmol/L), and correlates of PAP were similar in both cohorts. In CHS, PAP levels increased with age (r=0. 30), procoagulant factors (eg, factor VIIc, r=0.15), thrombin activity (prothrombin fragment F1+2, r=0.29), and inflammation-sensitive proteins (eg, fibrinogen, r=0.44; factor VIIIc, r=0.37). PAP was associated with increased atherosclerosis as measured by the ankle-arm index (AAI) (P for trend, +info)
Relative contribution of insulin and its precursors to fibrinogen and PAI-1 in a large population with different states of glucose tolerance. The Insulin Resistance Atherosclerosis Study (IRAS). (8/1717)Hyperinsulinemia is associated with the development of coronary heart disease. However, the underlying mechanisms are still poorly understood. Hypercoagulability and impaired fibrinolysis are possible candidates linking hyperinsulinism with atherosclerotic disease, and it has been suggested that proinsulin rather than insulin is the crucial pathophysiological agent. The aim of this study was to investigate the relationship of insulin and its precursors to markers of coagulation and fibrinolysis in a large triethnic population. A strong and independent relationship between plasminogen activator inhibitor-1 (PAI-1) antigen and insulin and its precursors (proinsulin, 32-33 split proinsulin) was found consistently across varying states of glucose tolerance (PAI-1 versus fasting insulin [proinsulin], r=0.38 [r=0.34] in normal glucose tolerance; r=0.42 [r=0.43] in impaired glucose tolerance; and r=0.38 [r=0.26] in type 2 diabetes; all P<0.001). The relationship remained highly significant even after accounting for insulin sensitivity as measured by a frequently sampled intravenous glucose tolerance test. In a stepwise multiple regression model after adjusting for age, sex, ethnicity, and clinic, both insulin and its precursors were significantly associated with PAI-1 levels. The relationship between fibrinogen and insulin and its precursors was significant in the overall population (r=0.20 for insulin and proinsulin; each P<0.001) but showed a more inconsistent pattern in subgroup analysis and after adjustments for demographic and metabolic variables. Stepwise multiple regression analysis showed that proinsulin (split products) but not fasting insulin significantly contributed to fibrinogen levels after adjustment for age, sex, clinic, and ethnicity. Decreased insulin sensitivity was independently associated with higher PAI-1 and fibrinogen levels. In summary, we were able to demonstrate an independent relationship of 2 crucial factors of hemostasis, fibrinogen and PAI-1, to insulin and its precursors. These findings may have important clinical implications in the risk assessment and prevention of macrovascular disease, not only in patients with overt diabetes but also in nondiabetic subjects who are hyperinsulinemic.

Effects of antioxidant vitamins C and E on endothelial function and thrombosis/fibrinolysis system in smokers. - Oxford...
Smoking is associated with endothelial dysfunction and abnormalities in thrombosis/fibrinolysis system, possibly through increased oxidative stress. In this study we investigated the effect of combined antioxidant treatment with vitamins C and E on endothelial function and plasma levels of plasminogen activator inhibitor (PAI-1), von Willebrand factor (vWF), tissue plasminogen activator (tPA) and factor VII (fVII), in smokers. Forty-one healthy smokers were randomly divided into 4 groups receiving vitamin C 2g/day (group A), vitamin C 2g/day plus vitamin E 400 IU/day (group B), vitamin C 2g/day plus vitamin E 800 IU/day (group C) or no antioxidants (controls, group D), for 4 weeks. Forearm blood flow was measured using venous occlusion strain-gauge plethysmography. Forearm vasodilatory response to reactive hyperemia (RH%) or to sublingual nitroglycerin administration (NTG%) were considered as indexes of endothelium dependent or independent dilation respectively. After treatment, RH% was increased only
Fibrinolysis - Wikipedia
Fibrinolysis is a process that prevents blood clots from growing and becoming problematic. This process has two types: primary fibrinolysis and secondary fibrinolysis. The primary type is a normal body process, whereas secondary fibrinolysis is the breakdown of clots due to a medicine, a medical disorder, or some other cause. In fibrinolysis, a fibrin clot, the product of coagulation, is broken down. Its main enzyme plasmin cuts the fibrin mesh at various places, leading to the production of circulating fragments that are cleared by other proteases or by the kidney and liver. Plasmin is produced in an inactive form, plasminogen, in the liver. Although plasminogen cannot cleave fibrin, it still has an affinity for it, and is incorporated into the clot when it is formed. Tissue plasminogen activator (t-PA) and urokinase are the agents that convert plasminogen to the active plasmin, thus allowing fibrinolysis to occur. t-PA is released into the blood very slowly by the damaged endothelium of the ...
Coagulation and fibrinolysis in injured patients | Journal of Clinical Pathology
Serial changes in coagulation and fibrinolysis studied among 42 patients admitted to hospital with a wide variety of injuries are reported. The first hours after trauma are dominated by an acceleration of fibrinolysis (clot lysis) and clotting time which are often followed by an abrupt rebound to prolonged fibrinolysis and normal clotting. Evidence is presented that acceleration of fibrinolysis is due to flooding of the circulation by plasminogen activator and that prolongation is probably due to an inhibitor. A prolonged prothrombin time, increased prothrombin consumption index, an acceleration of the heparin-retarded clotting time, and a fall in the platelet count are also frequent during the first hours after injury. There is evidence also of an early deficiency in factor V and the onset of a fall in factor VII and prothrombin.. The following days are characterized by continued prolongation of fibrinolysis, a lengthening of clotting time, and an increased prothrombin consumption index ...

The local fibrinolytic activity generated in the leg and arm veins during venous occlusion (fibrinolytic capacity) and the systemic fibrinolytic activity were measured at intervals in 11 patients after fracture of the femoral shaft and in 11 patients after acute myocardial infarction. In both groups the fibrinolytic capacity of the leg veins and the systemic fibrinolytic activity were significantly reduced two days after the onset of tissue injury. The fibrinolytic capacity of the arm veins was not altered. These results provide a possible explanation for the predilection of venous thrombosis for the leg veins after accidental trauma and acute myocardial infarction. ...

Impaired fibrinolysis-inducing capacity for postinjury phenotype of cultivated human arterial and human atherosclerotic intimal...
Impaired fibrinolysis is believed to promote atherosclerosis and contribute to myocardial infarction. The major triggering factor for fibrinolysis is vascular tissue plasminogen activator (t-PA), and the aim of this study was to evaluate the capacity of human arterial smooth muscle cells (SMC) for induction of fibrinolysis. SMC were plated on labeled fibrin gels, and lysis was measured as release of label. Fibrinolytic capacity was dependent on the phenotypic state of SMC. The multilayered phenotype to which SMC modulate after cellular injury had a much lower fibrinolysis-inducing capacity than the more ordinary monolayered SMC type. Fibrinolysis was mediated by activation of plasminogen. In long-term experiments under conditions imitating thrombolysis, platelet-derived growth factor promoted fibrinolysis indirectly by increase of SMC number, and a direct effect on cellular production of t-PA was not detected. SMC from atherosclerotic intima had a much lower capacity for induction of ...

Prevalence of Clinical and Laboratory Markers of Hypofibrinolysis in Psychotic Patients - Full Text View - ClinicalTrials.gov
If the thrombotic tendency plays a significant role in the etiology of psychosis, one would expect to find ischemic brain injuries in neuroimaging studies, but it does not happen. Therefore, if there is a correlation between thrombotic tendency-hypofibrinolysis and psychosis it is likely to occur at the biochemical level, such as in neuronal transmission.. The investigators hypothesis is that mechanisms that inhibit tissue plasminogen activator (t-PA) and therefore promote hypofibrinolysis, are directly or indirectly involved in the genesis of psychosis, because t-PA participates in neuronal plasticity and low t-PA levels are related to dementia.. Hypofibrinolysis due to t-PA inhibition can be seen in:. ...
A Method for Studying Changes in Profibrinolysin Titer in Dogs Following in Vivo Induction of Fibrinolytic Activity
A two-stage assay for canine profibrinolysin plasminogen is described. This assay is suitable for following in vivo changes in profibrinolysin titer induced by various experimental procedures. Plasma profibrinolysin is concentrated by a low ionic strength, protamine sulfate precipitation technic and activated with staphylokinase. Diluted aliquots of the activated solution are then assayed for fibrinolytic activity. One unit is that amount of activity which at 37 degrees C. and pH 7.25 will bring about lysis of 0.4 ml. of a 0.1 percent bovine fibrin clot in 300 seconds. The average dog plasma contains 19.4 units per milliliter. In general, increases in circulating fibrinolytic activity are associated with decreases in profibrinolysin.

Summary. Background: Activated factor XIII (FXIIIa), a transglutaminase, introduces fibrin-fibrin and fibrin-inhibitor cross-links, resulting in more mechanically stable clots. The impact of cross-linking on resistance to fibrinolysis has proved challenging to evaluate quantitatively. Methods: We used a whole blood model thrombus system to characterize the role of cross-linking in resistance to fibrinolytic degradation. Model thrombi, which mimic arterial thrombi formed in vivo, were prepared with incorporated fluorescently labeled fibrinogen, in order to allow quantification of fibrinolysis as released fluorescence units per minute. Results: A site-specific inhibitor of transglutaminases, added to blood from normal donors, yielded model thrombi that lysed more easily, either spontaneously or by plasminogen activators. This was observed both in the cell/platelet-rich head and fibrin-rich tail. Model thrombi from an FXIII-deficient patient lysed more quickly than normal thrombi; replacement ...

A case-control comparison within the framework of the prospective, multidisciplinary PLAT Study was performed to assess whether altered baseline fibrinolytic variables were associated with an elevated risk of ischemic thrombotic events in patients with documented coronary, cerebral, and/or peripheral atherosclerotic disease. Fibrinogen, D-dimer, tissue plasminogen activator (t-PA) antigen, and fibrinolytic activity before and after venous stasis (delta = difference between the two values), t-PA inhibitor, and lipid levels in 60 atherosclerotic patients with a thrombotic event during the first year of follow-up were compared with those in 94 atherosclerotic patients without such events, who were matched for age, sex, and diagnosis at enrollment. Events were associated with a higher release of delta t-PA antigen (P = .047), higher D-dimer (P = .024), and higher t-PA inhibitor (P = .001) levels. delta Fibrinolytic activity was correlated inversely with t-PA inhibitor (P , .01) and triglycerides (P ...

Association of pulse pressure with fibrinolysis in patients with type 2 diabetes.
INTRODUCTION: Pulse pressure is a potent risk factor for atherosclerotic disease. The purpose of this cross-sectional study was to determine whether pulse pressure is associated with blood coagulation and fibrinolysis in patients with diabetes. MATER
In this case, because the patient is hemodynamically stable and has no heart failure or contraindications to fibrinoysis, and because transfer for PCI would impose a further treatment delay, largely exceeding 60 minutes, fibrinolysis is the preferred option.3. Question: What if your community hospital is within 30 minutes from a centre that could perform a PCI and therefore both fibrinolysis and angioplasty are possible within appropriate time frames? What treatment option should be favoured?. Comment: We believe that both options would be acceptable and that it is reasonable in this case to select immediate on-site fibrinolysis because (a) the patient is not at very high risk in terms of her clinical presentation (no evidence of heart failure or hemodynamic instability; (b) the ischemic time is less than 3 hours, a time frame when fibrinolysis is most effective;2,3 and (c) the fibrinolytic risk of major bleeding is low. Commonly used fibrinolytics in Canada are the bolus agents tenecteplase and ...
Heiko Herwald - Lund University
Severe infectious diseases, including sepsis, remain a serious medical challenge worldwide. Clinical symptoms of patients suffering from sepsis are a culmination of complex interactions between the infecting microorganism and host immune responses, such as the induction of overwhelming inflammatory reactions, systemic activation of the coagulation system, and impaired fibrinolysis. These alarming findings prompted many research groups, including my own, to search for novel strategies to treat severe infectious diseases. Many of these approaches are focused on so-called host effector systems, since evidence has accumulated that complications from an infection are caused by an over-stimulation of host defense systems that are modulated by bacteria or bacterial products. In severe infections, such as sepsis and septic shock, vascular leakage, increased cytokine levels, and coagulation/fibrinolysis dysfunction are often observed.. My research projects aim to identify and characterize molecular ...

Thrombin-Activatable Fibrinolysis Inhibitor | Bentham Science
Title: Thrombin-Activatable Fibrinolysis Inhibitor. VOLUME: 11 ISSUE: 17. Author(s):Pauline F. Marx. Affiliation:Dept. Vascular Medicine, G1-114, Academic Medical Center, P.O. Box 22660, 1100 DD Amsterdam, The Netherlands.. Keywords:tafi, cpu, cpr, cpb, carboxypeptidase, coagulation, fibrinolysis. Abstract: The coagulation system is a potent mechanism that prevents blood loss after vascular injury. It consists of a number of linked enzymatic reactions resulting in thrombin generation. Thrombin converts soluble fibrinogen into a fibrin clot. The clot is subsequently removed by the fibrinolytic system upon wound healing. Thrombin-activatable fibrinolysis inhibitor (TAFI), which is identical to the previously identified proteins procarboxypeptidase B, R, and U, forms a link between blood coagulation and fibrinolysis. TAFI circulates as an inactive proenzyme in the bloodstream, and becomes activated during blood clotting. The active form, TAFIa, inhibits fibrinolysis by cleaving off C-terminal ...

Thrombin activatable fibrinolysis inhibitor (tafi) at the interface between coagulation and fibrinolysis
The thrombin-catalysed conversion of plasma fibrinogen into fibrin and the development of an insoluble fibrin clot are the final steps of the coagulation cascade during haemostasis. A delicate balance between coagulation and fibrinolysis determines the stability of the fibrin clot. Thrombin Activatable Fibrinolysis Inhibitor (TAFI) plays an important role in this process. TAFI is activated by thrombin and protects the fibrin clot against lysis. The role of TAFI in bleeding and thrombotic disorders is discussed as well as its novel emerging role in wound healing and inflammation ...
DIGITAL.CSIC: Structure of Activated Thrombin-Activatable Fibrinolysis Inhibitor, a Molecular Link between Coagulation and...
Thrombin-activatable fibrinolysis inhibitor (TAFI) is a metallocarboxypeptidase (MCP) that links blood coagulation and fibrinolysis. TAFI hampers fibrin-clot lysis and is a pharmacological target for the treatment of thrombotic conditions. TAFI is transformed through removal of its prodomain by thrombin-thrombomodulin into TAFIa, which is intrinsically unstable and has a short half-life in vivo. Here we show that purified bovine TAFI activated in the presence of a proteinaceous inhibitor renders a stable enzyme-inhibitor complex. Its crystal structure reveals that TAFIa conforms to the α/β-hydrolase fold of MCPs and displays two unique flexible loops on the molecular surface, accounting for structural instability and susceptibility to proteolysis. In addition, point mutations reported to enhance protein stability in vivo are mainly located in the first loop and in another surface region, which is a potential heparin-binding site. The protein inhibitor contacts both the TAFIa active site and an ...
Thrombin-activatable fibrinolysis inhibitor influences disease severity in humans and mice with pneumococcal meningitis -ORCA
Background Mortality and morbidity in patients with bacterial meningitis result from the proinflammatory response and dysregulation of coagulation and fibrinolysis. Thrombin-activatable fibrinolysis inhibitor (TAFI) is activated by free thrombin or thrombin in complex with thrombomodulin, and plays an antifibrinolytic role during fibrin clot degradation, but also has an anti-inflammatory role by inactivating proinflammatory mediators, such as complement activation products. Objective To assess the role of TAFI in pneumococcal meningitis. Methods We performed a prospective nationwide genetic association study in patients with bacterial meningitis, determined TAFI and complement levels in cerebrospinal fluid (CSF), and assessed the function of TAFI in a pneumococcal meningitis mouse model by using Cpb2 (TAFI) knockout mice. Results Polymorphisms (reference sequences: rs1926447 and rs3742264) in the CPB2 gene, coding for TAFI, were related to the development of systemic complications in patients ...
The Relation Between Serum P-selectin, Thrombin-activatable Fibrinolysis Inhibitor Levels, and Carotid Artery Intima-media...
Objective: Inflammation and migration of leukocytes to the brain parenchyma play a role in atherosclerosis and cerebral ischemic stroke. Migration occurs with the help of adhesion molecules on the surface of cerebral endothelial cells and leukocytes. P-selectin, an adhesion molecule, is present on the platelet and endothelial surface and allows leukocytes to loosely adhere to the endothelium, and its increase has been shown in acute ischemic stroke (AIS). Thrombin-activatable fibrinolysis inhibitor (TAFI) is a procarboxypeptidase molecule that can be another marker of AIS, which has been shown to increase the risk of thromboembolism and stroke 6-fold. Intima-media thickness (IMT) is thought to be associated with atherosclerotic diseases in carotid ultrasonography (USG) and increased risk of ischemic stroke has been found to be associated with increased carotid IMT. In this study, we investigated the relationship between P-selectin and TAFI levels, which have been shown to be effective for AIS ...
Fibrinolysis - Diapharma
Inhibition of Fibrinolysis. For maintaining high fidelity regulation between coagulatory clotting and proteolytic fibrinolysis TAFI (Thrombin activatable fibrinolysis inhibitor) plays an important inhibitory role. Apart from this, four different forms of plasminogen activator inhibitors, denoted PAI-1 to PAI-4, are also known.. PAI-1, which is the most prominent form, is mainly synthesized in endothelial cells and stored in thrombocytes. Its release is concentrated to platelet rich clots leading to an increased thrombus resistance to fibrinolysis. Another fibrinolysis inhibitor is the plasmin inhibitor (α2-antiplasmin). FXIIIa makes it an initial clot stabilizer by rapidly and covalently binding this inhibitor to fibrin. The role of inhibiting plasmin is made directly by a 1:1-complex formation between plasmin and antiplasmin (PAP). PAP can be immunologically detected in plasma, and is therefore used as a diagnostic parameter for proving thrombosis.. Function of plasmin. The fibrinogen molecule ...
Secretion and Antifibrinolytic Function of TAFI from Human Platelets
Thrombin activatable fibrinolysis inhibitor (TAFI) is a human plasma-derived zymogen that is activated through proteolytic cleavage by thrombin, thrombin in complex with thrombomodulin, or plasmin. Active TAFI attenuates fibrinolysis by removing carboxyl-terminal lysine residues from partially degraded fibrin, thereby inhibiting a potent positive feedback loop in the fibrinolytic cascade. In addition to the plasma pool of TAFI arising from expression in the liver, a distinct pool of TAFI has been reported to be present in platelets. While the antifibrinolytic effect of plasma-derived TAFI has been well-documented by in vitro and in vivo clot lysis assays, characterization of the platelet-derived form has been limited. Here, we not only confirm the presence of TAFI in the medium of washed, thrombin-stimulated platelets, but also that platelet-derived TAFI is capable of attenuating platelet-rich thrombus lysis in vitro independently of plasma TAFI using a novel thrombus lysis assay. Fluorescent ...
Tissue plasminogen activator antigen and coronary heart disease. Prospective study and meta-analysis. - MRCPHRU
AIMS: To determine whether circulating tissue plasminogen activator (t-PA) antigen concentrations are prospectively related to risk of coronary heart disease (CHD) in the general population. METHODS AND RESULTS: We measured baseline concentrations of t-PA antigen in the stored serum samples of 606 CHD cases and 1227 controls nested in a prospective cohort of 5661 men monitored for 16 years, and conducted a meta-analysis of previous relevant studies to place our findings in context. Tissue plasminogen activator antigen values were strongly correlated with several vascular risk factors, including serum lipids, body mass index, alcohol consumption, and markers of systemic inflammation. In a comparison of men in the top third compared with those in the bottom third of baseline t-PA antigen values, the odds ratio for CHD was 2.20 (95% confidence interval (CI) 1.70-2.85) after adjustment for age and town only, but this fell to 1.48 (1.09-2.01) after further adjustment.

TY - CHAP. T1 - Plasmin-antiplasmin system. AU - Mutch, Nicola J.. AU - Booth, Nuala A.. PY - 2016/4/19. Y1 - 2016/4/19. N2 - Plasmin is the key enzyme involved in the dissolution of fibrin. It is produced from plasminogen, which is activated by a plasminogen activator; the two primary activators are tissue-type plasminogen activator (tPA) and urinary-type plasminogen activator (uPA), also called urokinase. The process is regulated by inhibitors, principally plasminogen activator inhibitor 1 (PAI-1), α2-antiplasmin (α2AP) and thrombin-activatable fibrinolysis inhibitor (TAFI). Crucial control is exerted by surfaces, such as fibrin or cells, with plasminogen activation not normally occurring in the circulation. Here we will consider the individual players of the fibrinolytic cascade and their specific locations and potential interactions. Key questions considered are the initiation of fibrinolysis and the most appropriate ways to measure abnormalities in disease situations.. AB - Plasmin is the ...
Biochemical characterization of bovine plasma thrombin-activatable fibrinolysis inhibitor (TAFI) | BMC Biochemistry | Full Text
TAFI is a plasma protein assumed to be an important link between coagulation and fibrinolysis. The three-dimensional crystal structures of authentic mature bovine TAFI (TAFIa) in complex with tick carboxypeptidase inhibitor, authentic full lenght bovine plasma thrombin-activatable fibrinolysis inhibitor (TAFI), and recombinant human TAFI have recently been solved. In light of these recent advances, we have characterized authentic bovine TAFI biochemically and compared it to human TAFI. The four N-linked glycosylation sequons within the activation peptide were all occupied in bovine TAFI, similar to human TAFI, while the sequon located within the enzyme moiety of the bovine protein was non-glycosylated. The enzymatic stability and the kinetic constants of TAFIa differed somewhat between the two proteins, as did the isoelectric point of TAFI, but not TAFIa. Equivalent to human TAFI, bovine TAFI was a substrate for transglutaminases and could be proteolytically cleaved by trypsin or thrombin/solulin

TY - JOUR. T1 - Fibrinolysis resistant fibrin deposits in lymph nodes with Hodgkins disease. AU - Adany, R.. AU - Szegedi, A.. AU - Ablin, R. J.. AU - Muszbek, L.. PY - 1988/1/1. Y1 - 1988/1/1. N2 - Extravasal fibrin deposition is frequently observed within and around tumorous tissues and has been implicated in various aspects of tumor growth. However, no adequate information has been available on the mechanism how intratumoral interstitial fibrin deposits escape a prompt elimination by the fibrinolytic system. In this study we provide immunomorphological evidence showing that fibrin deposits in lymph nodes with Hodgkins disease are stabilized and made resistant to fibrinolysis by factor XIII (FXIII) of blood coagulation. By double immunofluorescent labelling systems fibrin deposits were simultaneously stained for α2-antiplasmin (α2-AP), the main physiological inhibitor of fibrinolysis and in a number of nodular areas they were also labelled for plasmin(ogen). The detection of ...

Effect of low-dose heparin treatment on fibrinolysis in patients with previous myocardial infarction
Abstract The present study was designed to investigate whether medium-term, low-dose heparin treatment is able to affect the fibrinolytic system. In a randomized cross-over study 10 asymptomatic patients with previous (1-6 years) myocardial infarction underwent two sequential 15-day treatments, respectively, on heparin and on placebo (saline solution), preceded and separated by 10-day wash-out periods. Heparin (as calcium heparin, 12,500 IU in 0.5 ml) and saline (0.5 ml) were subcutaneously administered once a day at 8 a.m. Blood samples for fibrinolysis studies were withdrawn on the first and 15th day of each period immediately before and 4 h after heparin or saline administration before and after 10 min venous occlusion (VO) respectively. Four hours after the first heparin administration tissue plasminogen activator antigen (t-PA ag) levels significantly increased with respect to saline administration (p , 0.01 and p , 0.05, respectively). After 15-day heparin treatment a decrease in ...

OBJECTIVE: To examine the effect of vitamin C on forearm vasodilatory response to reactive hyperemia and on plasma level of plasminogen activator inhibitor 1 (PAI-1), von Willebrand factor (vWF), tissue plasminogen activator (tPA), antithrombin III (ATIII), proteins C and S, and factors V (fV) and VII (fVII) in patients with both type 2 diabetes and CAD. RESEARCH DESIGN AND METHODS: A total of 39 patients with type 2 diabetes and CAD were divided into two groups and received vitamin C (2 g/day) or no antioxidant for 4 weeks. Forearm blood flow was determined using venous occlusion gauge-strain plethysmography at baseline and after treatment. Forearm vasodilatory response to reactive hyperemia (RH%) or nitrate (NTG%) was defined as the percent change of flow from baseline to the maximum flow during reactive hyperemia or after administration of nitrate, respectively. Biochemical markers were determined by enzyme-linked immunosorbent assay (ELISA) or other standard methods. RESULTS: RH% was significantly
Endothelial fibrinolytic response onto an evolving matrix of fibrin | BMC Hematology | Full Text
Fibrin provides a temporary matrix at the site of vascular injury. The aims of the present work were (1) to follow fibrin formation and lysis onto the surface of human dermal microvascular endothelial cells (HMEC-1), and (2) to quantify the secretion of fibrinolytic components in the presence of fibrin. Fibrin clots at different fibrinogen concentrations were formed on top of (model 1) or beneath (model 2) the endothelial cells. Fibrin formation or lysis onto the surface of HMEC-1 cells, was followed by turbidity. Clot structure was visualized by laser scanning confocal microscopy (LSCM). The secretion of uPA and PAI-1 by HMEC-1 cells was quantified by ELISA. The rate of fibrin formation increased approximately 1.5-fold at low fibrinogen content (0.5 and 1 mg/mL; p | 0.05) compared to the condition without cells; however, it was decreased at 2 mg/mL fibrinogen (p | 0.05) and no differences were found at higher fibrinogen concentrations (3 and 5 mg/mL). HMEC-1 retarded dissolution of clots formed onto

Gene Polymorphisms for Plasminogen Activator Inhibitor-1/Tissue Plasminogen Activator and Development of Allograft Coronary...
Impaired fibrinolytic activity is known to play an integral role in the development of vascular disease.19 20 The degree of fibrinolytic dysfunction may be determined in vivo by analyzing levels and/or activity of fibrinolytic proteins (PAI-1, TPA) in plasma samples or by in situ analysis of tissue samples taken from diseased vessels. When detected in the plasma, impaired fibrinolytic activity correlates best with the occurrence of clinical events such as myocardial infarction and stroke but not clearly with angiographic or histological extent of atherosclerosis.19 21 In contrast, in situ evidence of impaired fibrinolytic activity clearly correlates with the extent of histological atherosclerosis. This may also be true for Tx CAD. In a recent study, allografts with depleted levels of arteriolar TPA (possibly as a result of complex formation with PAI-1) were at greater risk of developing earlier and more severe disease than those grafts with normal arteriolar TPA.4 In the case of the transplanted ...
Thrombomodulin favors leukocyte microvesicle fibrinolytic activity, reduces NETosis and prevents septic shock-induced...
According to the recently described immunothrombosis concept , adequate and controlled coagulation activation would stand for an essential innate immune defense mechanism. When over-activated, coagulation pathways however switch from a beneficial to an uncontrolled noxious response. Similarly, excessive neutrophil activation could have deleterious consequences, notably by sustaining coagulation through NETs formation. In the present study, we report that rhTM both impact coagulation and neutrophil activation, two main actors of immunothrombosis.. Sepsis is indeed always associated with the activation of the coagulation cascade , resulting in excessive thrombin formation, defective fibrinolysis and consumption of natural anticoagulant proteins, ultimately leading to DIC. Nevertheless, impairment of fibrinolysis plays a key role in microvascular thrombosis, responsible for multiple organ failure syndrome and death . Delayed fibrinolysis might therefore also contribute to septic ...

P8 We have studied the effect of valsartan treatment (3 and 10 mg/kg/day) on plasma fibrinolytic balance in normo- and hypercholesterolemic rabbits. Animals were fed a normal chow or an experimental diet containing 1% cholesterol for 10 weeks. Systolic blood pressure, as well as plasma cholesterol, dimer D, plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (tPA) were measured. Plasma cholesterol concentrations were higher in rabbits fed the experimental diet compared with control ones. None of the doses of valsartan were able to affect either plasma cholesterol or blood pressure levels in any group.As compared with control animals hypercholesterolemic rabbits presented lower dimer D (0.37±0.07 mg/ml vs 0.96±0.13, p,0.05) and tPA levels (0.27±0.003 ng/ml vs 0.31±0.007, p,0.05) but higher PAI-1 levels (11.1±0.9 ng/ml vs 8.84±0.04, p,0.05). In cholesterol-fed rabbits, valsartan treatment (3 or 10 mg/kg/day) significantly increased both dimer D (0.73±0.1 mg/ml and, ...

Blood coagulation and fibrinolytic factors have been measured in 13 patients treated by liver transplantation. During operation intravascular coagulation and fibrinolysis were increased, but seldom to a degree which would cause abnormal bleeding. Measurement of the catabolism of radioactive fibrinogen showed that increased intravascular coagulation continued for long periods after the operation. Despite secondarily increased fibrinolysis, there was a high incidence of thrombosis. Treatment with anticoagulants or with fibrinolysis inhibitors may be valuable in these patients.. ...

Colonies possessing enhanced fibrinolytic activity were not observed 8 days after treatment, but they were observed following one passage (2 weeks after treatment). Morphologically transformed colonies, which exhibited no enhanced fibrinolytic activity, were observed 8 days following treatment. In contrast to these two early changes, cells capable of growth in soft agar were observed much later (6 to 8 weeks after treatment). Untreated Syrian hamster embryo cells generally senesced and did not exhibit enhanced fibrinolytic activity. Approximately 1 of 10 untreated cultures escaped senescence and evolved as a continuous cell line; such cultures frequently exhibited enhanced fibrinolytic activity. ...
Pathological haemostasis and prothrombotic state in Behcets disease | AVESİS
Behcets disease (BD) is a widespread occlusive-type vasculitis with life-threatening manifestations. The vasculopathy of BD is unique and any type of vessel can be involved. Moreover, vascular lesions in BD represent an occlusive nature suggesting a hypercoagulable/prothrombotic state. The data concerning the genetic defects of the coagulation cascade are expanding. There is evidence of universal activation of haemostatic system in BD. Procoagulant markers of thrombosis are elevated reflecting intravenous excessive thrombin formation. Defective fibrinolysis with impaired fibrinolytic kinetics may have a role in the hypercoagulable/prothrombotic state of BD. Endothelial cell injury and/or pathological activation is well documented in BD. The aim of this paper is to review current literature knowledge and our experience regarding the unresolved complicated issues of genetic thrombotic defects, in vivo haemostatic markers, coagulation inhibitors, impaired fibrinolysis, and endothelial ...

Dr Nicola Mutch and Dr Claire Whyte win funding | British Society for Haemostasis & Thrombosis
The PhD studentship jointly funded by the BSH, Lifeblood and the BSHT has been awarded to Dr Nicola Mutch and Dr Claire Whyte from the University of Aberdeen for the following project:. The impact of thrombus composition on regulation of fibrinolysis under flow. Fibrin structure profoundly impacts a clots susceptibility to fibrinolysis with compact networks linked to early onset of coronary heart disease. Shear stress modulates the structure and cellular composition of thrombi in vivo, but most models of fibrinolysis do not account for flow. This project will develop a novel flow model which allows thrombus formation and lysis to be visualized in a single system. Using this novel model and our established Chandler model thrombi system, we will assess how shear rates that mimic venous and arterial circulation affect thrombus structure, composition and susceptibility to lysis. Using fluorescent confocal microscopy we will monitor movement of fibrinolytic proteases through thrombi of different ...
This study has investigated the effects of clamped hyperinsulinemic euglycemia and acute and repeated 2-h episodes of moderate hyperinsulinemic hypoglycemia (2.9 mmol/L) on endothelial function, fibrinolytic balance, and proinflammatory and proatherothrombotic mechanisms in healthy man. Our results demonstrate that acute hypoglycemia reduces endogenous NO-mediated endothelial vasodilation, activates inflammatory processes, impairs fibrinolytic balance, and increases proatherothrombotic mechanisms. Secondly, repeated episodes of hypoglycemia can further impair vascular function by additionally reducing both endogenous and exogenous NO-mediated endothelial function and increasing TAT complex formation.. Recent large randomized controlled trials investigating the effects of intensifying glucose control both in hospitals and in outpatient settings have demonstrated an association with hypoglycemia and severe cardiovascular outcomes and even death (5,8). The in vivo vascular pathophysiologic ...
PLAT gene - Genetics Home Reference - NIH
From NCBI Gene:. This gene encodes tissue-type plasminogen activator, a secreted serine protease that converts the proenzyme plasminogen to plasmin, a fibrinolytic enzyme. The encoded preproprotein is proteolytically processed by plasmin or trypsin to generate heavy and light chains. These chains associate via disulfide linkages to form the heterodimeric enzyme. This enzyme plays a role in cell migration and tissue remodeling. Increased enzymatic activity causes hyperfibrinolysis, which manifests as excessive bleeding, while decreased activity leads to hypofibrinolysis, which can result in thrombosis or embolism. Alternative splicing of this gene results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Jan 2016]. From UniProt: ...

Prevention of symptomatic thrombosis with short term (low molecular weight) heparin in patients with rheumatoid arthritis after...
VTE is a common complication in patients undergoing elective hip or knee surgery. Over the past 25 years several anticoagulant regimens have been shown to be effective, though no regimen offers complete protection.. Previous studies have suggested that the incidence of deep VTE in patients with RA undergoing hip or knee surgery is three to 10 times less than in patients with osteoarthritis.3 4 The explanation is likely to be multifactorial: patients with RA are on average younger, their body weight is lower, their haemoglobin is lower, and reports have been published indicating that their fibrinolytic activity is higher4 8; however, recent publications also seem to find the lower fibrinolytic activity. Another explanation for the lower rate of thromboembolic complications in patients with RA may be the frequent use of NSAIDs, with their antiplatelet activity.4 In 1994 an overview of randomised trials of antiplatelet treatment showed a significant, clinically important reduction in thrombosis and ...

Characterization of Shear-Sensitive Genes in the NormalRat Aorta Identifies Hand2 as a Major Flow-ResponsiveTranscription Factor
Cardiovascular disease (CVD) is the major cause of death worldwide. Underlying causes, such as atherosclerosis and hypertension, are associated with remodeling of the vessel wall ultimately leading to loss of structural integrity. There are a number of factors that can influence vascular remodeling and hence structural integrity. The overall aim of this thesis was to investigate aortic wall integrity in relation to genetics and blood flow.. The influence of SNPs within the currently most robust susceptibility locus identified for CVD (chromosome 9p21.3) on abdominal aortic integrity was studied in elderly individuals. In men, risk-variants were associated with a decreased abdominal aortic stiffness, independent of other factors related to arterial stiffness. Impaired mechanical properties of the abdominal aortic wall may explain the association between chromosome 9p21.3 and vascular disease.. Plasminogen activator inhibitor 1 (PAI-1) is the key inhibitor of fibrinolysis, and involved in several ...
How Endovan works in endometriosis
Endovan increases the fibrinolytic activity (fibrin-degrading) in the blood by encouraging increased plasmin production as well as by mimicking the function of plasmin.. With a more robust plasmin response, the body is better able to break down accumulated fibrin allowing the immune system to clean up the site and direct the debris to be processed as waste.. Try Endovan Today. ...
