Blood Coagulation Factor Inhibitors: Substances, usually endogenous, that act as inhibitors of blood coagulation. They may affect one or multiple enzymes throughout the process. As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria.Blood Coagulation: The process of the interaction of BLOOD COAGULATION FACTORS that results in an insoluble FIBRIN clot.Blood Coagulation Factors: Endogenous substances, usually proteins, that are involved in the blood coagulation process.Factor XIII: A fibrin-stabilizing plasma enzyme (TRANSGLUTAMINASES) that is activated by THROMBIN and CALCIUM to form FACTOR XIIIA. It is important for stabilizing the formation of the fibrin polymer (clot) which culminates the coagulation cascade.Factor IX: Storage-stable blood coagulation factor acting in the intrinsic pathway. Its activated form, IXa, forms a complex with factor VIII and calcium on platelet factor 3 to activate factor X to Xa. Deficiency of factor IX results in HEMOPHILIA B (Christmas Disease).Factor X: Storage-stable glycoprotein blood coagulation factor that can be activated to factor Xa by both the intrinsic and extrinsic pathways. A deficiency of factor X, sometimes called Stuart-Prower factor deficiency, may lead to a systemic coagulation disorder.Factor Xa: Activated form of factor X that participates in both the intrinsic and extrinsic pathways of blood coagulation. It catalyzes the conversion of prothrombin to thrombin in conjunction with other cofactors.Factor VII: Heat- and storage-stable plasma protein that is activated by tissue thromboplastin to form factor VIIa in the extrinsic pathway of blood coagulation. The activated form then catalyzes the activation of factor X to factor Xa.Factor VIII: Blood-coagulation factor VIII. Antihemophilic factor that is part of the factor VIII/von Willebrand factor complex. Factor VIII is produced in the liver and acts in the intrinsic pathway of blood coagulation. It serves as a cofactor in factor X activation and this action is markedly enhanced by small amounts of thrombin.Factor XIa: Activated form of factor XI. In the intrinsic pathway, Factor XI is activated to XIa by factor XIIa in the presence of cofactor HMWK; (HIGH MOLECULAR WEIGHT KININOGEN). Factor XIa then activates factor IX to factor IXa in the presence of calcium.Blood Coagulation Tests: Laboratory tests for evaluating the individual's clotting mechanism.Thromboplastin: Constituent composed of protein and phospholipid that is widely distributed in many tissues. It serves as a cofactor with factor VIIa to activate factor X in the extrinsic pathway of blood coagulation.Factor VIIa: Activated form of factor VII. Factor VIIa activates factor X in the extrinsic pathway of blood coagulation.Antirheumatic Agents: Drugs that are used to treat RHEUMATOID ARTHRITIS.Blood Coagulation Disorders: Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors such as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.Factor XI: Stable blood coagulation factor involved in the intrinsic pathway. The activated form XIa activates factor IX to IXa. Deficiency of factor XI is often called hemophilia C.Factor IXa: Activated form of factor IX. This activation can take place via the intrinsic pathway by the action of factor XIa and calcium, or via the extrinsic pathway by the action of factor VIIa, thromboplastin, and calcium. Factor IXa serves to activate factor X to Xa by cleaving the arginyl-leucine peptide bond in factor X.Coagulants: Agents that cause clotting.Factor V: Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.Prothrombin: A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.Disseminated Intravascular Coagulation: A disorder characterized by procoagulant substances entering the general circulation causing a systemic thrombotic process. The activation of the clotting mechanism may arise from any of a number of disorders. A majority of the patients manifest skin lesions, sometimes leading to PURPURA FULMINANS.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.Prothrombin Time: Clotting time of PLASMA recalcified in the presence of excess TISSUE THROMBOPLASTIN. Factors measured are FIBRINOGEN; PROTHROMBIN; FACTOR V; FACTOR VII; and FACTOR X. It is used for monitoring anticoagulant therapy with COUMARINS.Thrombin: An enzyme formed from PROTHROMBIN that converts FIBRINOGEN to FIBRIN.Factor XII: 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.Factor Va: Activated form of factor V. It is an essential cofactor for the activation of prothrombin catalyzed by factor Xa.Protein C: A vitamin-K dependent zymogen present in the blood, which, upon activation by thrombin and thrombomodulin exerts anticoagulant properties by inactivating factors Va and VIIIa at the rate-limiting steps of thrombin formation.Factor VIIIa: Activated form of factor VIII. The B-domain of factor VIII is proteolytically cleaved by thrombin to form factor VIIIa. Factor VIIIa exists as a non-covalent dimer in a metal-linked (probably calcium) complex and functions as a cofactor in the enzymatic activation of factor X by factor IXa. Factor VIIIa is similar in structure and generation to factor Va.1-Carboxyglutamic Acid: Found in various tissues, particularly in four blood-clotting proteins including prothrombin, in kidney protein, in bone protein, and in the protein present in various ectopic calcifications.Hemophilia B: A deficiency of blood coagulation factor IX inherited as an X-linked disorder. (Also known as Christmas Disease, after the first patient studied in detail, not the holy day.) Historical and clinical features resemble those in classic hemophilia (HEMOPHILIA A), but patients present with fewer symptoms. Severity of bleeding is usually similar in members of a single family. Many patients are asymptomatic until the hemostatic system is stressed by surgery or trauma. Treatment is similar to that for hemophilia A. (From Cecil Textbook of Medicine, 19th ed, p1008)Receptors, Tumor Necrosis Factor: Cell surface receptors that bind TUMOR NECROSIS FACTORS and trigger changes which influence the behavior of cells.Vitamin K: A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.Arthritis, Rheumatoid: A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.Transglutaminases: Transglutaminases catalyze cross-linking of proteins at a GLUTAMINE in one chain with LYSINE in another chain. They include keratinocyte transglutaminase (TGM1 or TGK), tissue transglutaminase (TGM2 or TGC), plasma transglutaminase involved with coagulation (FACTOR XIII and FACTOR XIIIa), hair follicle transglutaminase, and prostate transglutaminase. Although structures differ, they share an active site (YGQCW) and strict CALCIUM dependence.Hemophilia A: The classic hemophilia resulting from a deficiency of factor VIII. It is an inherited disorder of blood coagulation characterized by a permanent tendency to hemorrhage.Tumor Necrosis Factor Decoy Receptors: A subclass of tumor necrosis family receptors that lack cell signaling domains. They bind to specific TNF RECEPTOR LIGANDS and are believed to play a modulating role in the TNF signaling pathway. Some of the decoy receptors are products of distinct genes, while others are products of ALTERNATIVE SPLICING of the MRNA for the active receptor.Antithrombin III: A plasma alpha 2 glycoprotein that accounts for the major antithrombin activity of normal plasma and also inhibits several other enzymes. It is a member of the serpin superfamily.Inhibitor of Differentiation Proteins: Inhibitor of differentiation proteins are negative regulators of BASIC HELIX-LOOP-HELIX TRANSCRIPTION FACTORS. They inhibit CELL DIFFERENTIATION and induce CELL PROLIFERATION by modulating different CELL CYCLE regulators.Tumor Necrosis Factor-alpha: Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.Arcidae: A family of ark shell mollusks, in the class BIVALVIA. They have soft bodies with platelike GILLS enclosed within two shells hinged together.Fibrinogen: 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.Thrombelastography: Use of a thrombelastograph, which provides a continuous graphic record of the physical shape of a clot during fibrin formation and subsequent lysis.Antithrombins: Endogenous factors and drugs that directly inhibit the action of THROMBIN, usually by blocking its enzymatic activity. They are distinguished from INDIRECT THROMBIN INHIBITORS, such as HEPARIN, which act by enhancing the inhibitory effects of antithrombins.Fibrin: A protein derived from FIBRINOGEN in the presence of THROMBIN, which forms part of the blood clot.Anticoagulants: Agents that prevent clotting.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Antibodies, Monoclonal: Antibodies produced by a single clone of cells.Hemostasis: The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Vitamin K Deficiency: A nutritional condition produced by a deficiency of VITAMIN K in the diet, characterized by an increased tendency to hemorrhage (HEMORRHAGIC DISORDERS). Such bleeding episodes may be particularly severe in newborn infants. (From Cecil Textbook of Medicine, 19th ed, p1182)Immunoglobulin G: The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.Antibodies, Monoclonal, Humanized: Antibodies from non-human species whose protein sequences have been modified to make them nearly identical with human antibodies. If the constant region and part of the variable region are replaced, they are called humanized. If only the constant region is modified they are called chimeric. INN names for humanized antibodies end in -zumab.Benzamidines: Amidines substituted with a benzene group. Benzamidine and its derivatives are known as peptidase inhibitors.Binding Sites: The parts of a macromolecule that directly participate in its specific combination with another molecule.Factor XII Deficiency: An absence or reduced level of blood coagulation factor XII. It normally occurs in the absence of patient or family history of hemorrhagic disorders and is marked by prolonged clotting time.Fibrinolysis: The natural enzymatic dissolution of FIBRIN.Immunologic Factors: Biologically active substances whose activities affect or play a role in the functioning of the immune system.Factor XIIa: Activated form of factor XII. In the initial event in the intrinsic pathway of blood coagulation, kallikrein (with cofactor HIGH MOLECULAR WEIGHT KININOGEN) cleaves factor XII to XIIa. Factor XIIa is then further cleaved by kallikrein, plasmin, and trypsin to yield smaller factor XII fragments (Hageman-Factor fragments). These fragments increase the activity of prekallikrein to kallikrein but decrease the procoagulant activity of factor XII.

Identification and purification of vitamin K-dependent proteins and peptides with monoclonal antibodies specific for gamma -carboxyglutamyl (Gla) residues. (1/55)

Novel monoclonal antibodies that specifically recognize gamma-carboxyglutamyl (Gla) residues in proteins and peptides have been produced. As demonstrated by Western blot and time-resolved immunofluorescence assays the antibodies are pan-specific for most or all of the Gla-containing proteins tested (factors VII, IX, and X, prothrombin, protein C, protein S, growth arrest-specific protein 6, bone Gla protein, conantokin G from a cone snail, and factor Xa-like proteins from snake venom). Only the Gla-containing light chain of the two-chain proteins was bound. Decarboxylation destroyed the epitope(s) on prothrombin fragment 1, and Ca(2+) strongly inhibited binding to prothrombin. In Western blot, immunofluorescence, and surface plasmon resonance assays the antibodies bound peptides conjugated to bovine serum albumin that contained either a single Gla or a tandem pair of Gla residues. Binding was maintained when the sequence surrounding the Gla residue(s) was altered. Replacement of Gla with glutamic acid resulted in a complete loss of the epitope. The utility of the antibodies was demonstrated in immunochemical methods for detecting Gla-containing proteins and in the immunopurification of a factor Xa-like protein from tiger snake venom. The amino acid sequences of the Gla domain and portions of the heavy chain of the snake protein were determined.  (+info)

The role of coagulation abnormalities in the development of Perthes' disease. (2/55)

Recent reports have suggested an association between Perthes' disease and an underlying thrombophilic or hypofibrinolytic tendency. In Northern Ireland there is a high incidence of Perthes' disease (11.7 per 100,000 or 1 in 607 children) in a stable paediatric population. We reviewed 139 children with Perthes' disease and compared them with a control group of 220 aged- and gender-matched healthy primary schoolchildren with similar racial and ethnic backgrounds. There were no significant deficiencies of antithrombotic factors protein C, protein S, antithrombin III or resistance to activated protein C. A total of 53 (38.1%) of the children with Perthes' disease had a prolonged activated partial thromboplastin time (>38) compared with 13 (5.9%) of the control group (p < 0.001). Our findings have shown that using standard assays, thrombophilia secondary to antithrombotic factor deficiency or resistance to activated protein does not appear to be an aetiological factor for Perthes' disease. The cause of the prolonged activated partial thromboplastin time, usually associated with a clotting factor deficiency, is under further investigation.  (+info)

Factor V Leiden mutation, prothrombin gene mutation, and deficiencies in coagulation inhibitors associated with Budd-Chiari syndrome and portal vein thrombosis: results of a case-control study. (3/55)

In a collaborative multicenter case-control study, we investigated the effect of factor V Leiden mutation, prothrombin gene mutation, and inherited deficiencies of protein C, protein S, and antithrombin on the risk of Budd-Chiari syndrome (BCS) and portal vein thrombosis (PVT). We compared 43 BCS patients and 92 PVT patients with 474 population-based controls. The relative risk of BCS was 11.3 (95% CI 4.8-26.5) for individuals with factor V Leiden mutation, 2.1(95% CI 0.4-9.6) for those with prothrombin gene mutation, and 6.8 (95% CI 1.9-24.4) for those with protein C deficiency. The relative risk of PVT was 2.7 (95% CI 1.1-6.9) for individuals with factor V Leiden mutation, 1.4 (95% CI 0.4-5.2) for those with prothrombin gene mutation, and 4.6 (95% CI 1.5-14.1) for those with protein C deficiency. The relative risk of BCS or PVT was not increased in the presence of inherited protein S or antithrombin deficiency. Concurrence of either acquired or inherited thrombotic risk factors was observed in 26% of the BCS patients and 37% of the PVT patients. We conclude that factor V Leiden mutation and hereditary protein C deficiency appear to be important risk factors for BCS and PVT. Although the prevalence of the prothrombin gene mutation was increased, it was not found to be a significant risk factor for BCS and PVT. The coexistence of thrombogenic risk factors in many patients indicates that BCS and PVT can be the result of a combined effect of different pathogenetic mechanisms.  (+info)

Structural basis for inhibition promiscuity of dual specific thrombin and factor Xa blood coagulation inhibitors. (4/55)

BACKGROUND: A major current focus of pharmaceutical research is the development of selective inhibitors of the blood coagulation enzymes thrombin or factor Xa to be used as orally bioavailable anticoagulant drugs in thromboembolic disorders and in the prevention of venous and arterial thrombosis. Simultaneous direct inhibition of thrombin and factor Xa by synthetic proteinase inhibitors as a novel approach to antithrombotic therapy could result in potent anticoagulants with improved pharmacological properties. RESULTS: The binding mode of such dual specific inhibitors of thrombin and factor Xa was determined for the first time by comparative crystallography using human alpha-thrombin, human des-Gla (1--44) factor Xa and bovine trypsin as the ligand receptors. The benzamidine-based inhibitors utilize two different conformations for the interaction with thrombin and factor Xa/trypsin, which are evoked by the steric requirements of the topologically different S2 subsites of the enzymes. Compared to the unliganded forms of the proteinases, ligand binding induces conformational adjustments of thrombin and factor Xa active site residues indicative of a pronounced induced fit mechanism. CONCLUSION: The structural data reveal the molecular basis for a desired unselective inhibition of the two key components of the blood coagulation cascade. The 4-(1-methyl-benzimidazole-2-yl)-methylamino-benzamidine moieties of the inhibitors are able to fill both the small solvent accessible as well as the larger hydrophobic S2 pockets of factor Xa and thrombin, respectively. Distal fragments of the inhibitors are identified which fit into both the cation hole/aromatic box of factor Xa and the hydrophobic aryl binding site of thrombin. Thus, binding constants in the medium-to-low nanomolar range are obtained against both enzymes.  (+info)

The dynamics of thrombin formation. (5/55)

The central event of the hemostatic process is the generation of thrombin through the tissue factor pathway. This is a highly regulated, dynamic process in which thrombin itself plays many roles, positively and negatively its production and destruction. The hemostatic process is essential to normal physiology and is also the Achilles heel of our aging population. The inappropriate generation of thrombin may lead to vascular occlusion with the consequence of myocardial infarction, stroke, pulmonary embolism, or venous thrombosis. In this review, we summarize our present views regarding the tissue factor pathway by which thrombin is generated and the roles played by extrinsic and intrinsic factor Xa generating complexes in hemostasis and the roles of the stoichiometric and dynamic inhibitors that regulate thrombin generation.  (+info)

Thrombotic risk factors and extent of liver fibrosis in chronic viral hepatitis. (6/55)

BACKGROUND AND AIMS: Thrombosis of the small intrahepatic veins has been suggested to trigger liver tissue remodelling. We evaluated the prevalence of multiple thrombotic risk factors and their association with the extent of fibrosis in chronic viral hepatitis. METHODS: Ninety consecutive patients with chronic hepatitis B or C without malignancy, a history of venous thrombosis, or antiviral/immunosuppressive therapy within the last six months were included. Thrombophilic and coagulation factors were evaluated on the liver biopsy day. RESULTS: One or more thrombotic risk factors were found in 68% and > or =2 factors in 37% of patients. Higher necroinflammatory activity was independently associated with higher prothrombin time (p=0.003), alanine aminotransferase level (p=0.011), and histological staging (p=0.018). Patients with staging scores of 4-6 compared with those with scores of 0-3 more frequently had deficiency of protein C (24% v 3%; p=0.007), antithrombin III (28% v 5%; p=0.005), and plasminogen (19% v 2%; p=0.03), and a trend for more frequent activated protein C resistance (8% v 0%; p=0.075). The presence of > or =1 significant thrombotic risk factor was observed in 11/25 (44%) patients with staging scores of 4-6 and in 6/65 (9%) patients with scores of 0-3 (p<0.001), being the only variable independently associated with advanced staging (odds ratio 2.4, p=0.02). CONCLUSIONS: Thrombotic risk factors are frequently detected in patients with chronic viral hepatitis and the presence of > or =1 significant factor is associated with more advanced fibrosis. Whether the association of such thrombophilic conditions with advanced fibrosis is a primary or secondary phenomenon and whether their development in combination with local inflammation accelerate the progression of liver fibrosis need further evaluation.  (+info)

Mikamo Lecture: a radical view on the 'superfamily' of cardiovascular risk factors. (7/55)

Many risk factors for cardiovascular disease generate superoxide in the blood vessels and thereby impair endothelial function. To emphasize the critical role of oxygen radicals, this is a 'radical view' of those risk factors. It will be useful to organize risk factors into a 'superfamily', with consideration of mediators, mechanisms, and target organs. Studies are summarized which suggest that, in parallel with the impairment of endothelial vasomotor function, the thrombin/thrombomodulin/activated protein C anticoagulant mechanism, which requires endothelial thrombomodulin, is also impaired by atherosclerosis and improves during regression of atherosclerosis. Impairment of the anticoagulant mechanism may contribute to thrombosis in atherosclerotic arteries, and improvement of the anticoagulant mechanism during regression of atherosclerosis may reduce the risk of cardiovascular events.  (+info)

Time course of coagulation parameters, cytokines and adhesion molecules in Plasmodium falciparum malaria. (8/55)

We studied 38 patients with malaria tropica over a period of 5 days during antiparasitic therapy. Serum or plasma levels of interleukin (IL) 1beta, IL-6, IL-10, tumour necrosis factor-alpha (TNF-alpha), the soluble vascular adhesion molecule (sVCAM) and the soluble intracellular adhesion molecule (sICAM) were determined by enzyme-linked immunosorbent assay. Protein C and antithrombin III activity were analysed by chromogenic tests and protein S activity by a clotting test. Antithrombin III, protein C and protein S activity was significantly lower in patients with severe malaria and displayed a highly significant increase in activity over the time of evaluation. Levels of sVCAM and sICAM were increased for the whole study period, but no significant differences were found between severe and mild malaria cases. Serum IL-1beta, IL-6 and IL-10 levels were significantly higher in patients with severe malaria, whereas no significant differences were found for TNF-alpha. IL-6 and IL-10 decreased significantly over 5 days during schizontocidal therapy. Our data show an impairment of the coagulation system which correlates with pro-inflammatory cytokines and therefore with the severity of the disease.  (+info)

Title: PARP Inhibitor Development for Systemic Cancer Targeting. VOLUME: 7 ISSUE: 5. Author(s):Tomasz Zaremba and Nicola Jane Curtin. Affiliation:Newcastle University,Northern Institute for Cancer Research, Paul OGorman Building, Medical School, Framlington Place, Newcastle upon Tyne, NE2 4HH, UK.. Keywords:Base excision repair/single strand break repair, Poly(ADP-ribose) polymerase-1 (PARP-1), PARP inhibitors. Abstract: Poly(ADP-ribose) polymerase 1 (PARP-1) is a DNA-binding enzyme that is activated by DNA breaks, converting them into an intracellular signal via poly(ADP-ribosyl)ation of nuclear proteins. Negatively charged polymers of ADP-ribose (PAR) attached to PARP-1 itself and histones lead to chromatin relaxation, facilitating the access of base excision/single strand break repair proteins and activating these repair enzymes. PARP inhibitors have been developed to investigate the role of PARP-1 in cell biology and to overcome DNA repair-mediated resistance of cancer cells to cytotoxic ...

Objective: The antioxidant activity of vitamin E is derived primarily from alpha-tocopherol (α-T) and gammatocopherol (γ-T). Results of epidemiological studies have demonstrated an inverse relationship between vitamin E intake and coronary disease. However, the results of clinical trials using α-T are equivocal. We determined the effect of 5 weeks of 100 mg/d or 200 mg/d γ-T supplementation on thrombotic markers such as platelet reactivity, lipid profile and the inflammation marker C-reactive protein (CRP). Methods and results: Fourteen healthy subjects consumed 100 mg/day while 13 consumed 200 mg/d of γ-T and 12 received placebo (soybean capsules with less than 5 mg/d γ-T) in a double-blinded parallel study design. Fasting pre and post dose blood samples were analysed. Blood γ-T concentrations increased significantly (p,0.05) relative to dose during the intervention period. Both groups receiving active ingredients showed significantly lower platelet activation after supplementation ...
In this study, we used whole-genome array analysis and pharmacological reagents to identify PROCR as a potential Cn/NFAT-dependent gene in vascular smooth muscle. We corroborate the only report to date that vascular SMCs do express the protein C receptor (PROCR).15 More importantly, we validate our informatics approach and are the first to report Cn/NFAT signaling as a regulator of PROCR activation. We show PDGF-BB stimulation induced PROCR expression in a Cn/NFAT-dependent manner at both the transcriptional and translational levels. Mutation of a highly conserved NFAT binding motif significantly attenuated PROCR promoter activation, supporting the NFAT-dependent property of PROCR activity. In addition, PROCR expression is upregulated in vivo as a result of acute vascular injury, highlighting the potential role of PROCR in vessel restenosis.. Until the recent detection of PROCR in vascular SMCs, PROCR was believed to be expressed predominantly in ECs. Studies to date on PROCR transcription focus ...

Acquired factor VIII (FVIII) inhibitor induces a bleeding disorder caused by specific antibodies to FVIII. The cause of approximately one fifth of cases can be attributed to autoimmune disorders, such as pemphigus. Here, we describe a case of refractory acquired FVIII inhibitor in a patient with primary pemphigus and its successful treatment with low-dose rituximab. Coagulation studies revealed a prolonged activated partial thromboplastin time, which could not be corrected with the mixing test. At the same time, the FVIII activity level was significantly reduced, and the FVIII inhibitor titer was elevated. A treatment regimen with prednisolone/cyclophosphamide followed by prednisolone/cyclosporine was used. The patient temporarily responded but then became resistant to these medicines. However, subsequent treatment with low-dose rituximab achieved considerable clinical and laboratory improvement in the same patient. Follow-up at 6 months revealed a low level of residual FVIII inhibitor activity ...
At least five genes from the gibberellin (GA) biosynthesis pathway are clustered on chromosome 4 of knockout mutant identified alleles at the 3 consensus sequence of intron 2 in the mutant, resulting in reduced levels of active protein due to a splicing defect in the mutant. biosynthesis follows the isoprenoid pathway to geranylgeranyl diphosphate (GGPP), which, in plants, undergoes a two-step cyclization reaction in which GGPP is converted to and through a shared promoter. Using gene disruption and by expressing in the GA-deficient mutant SG139, which lacks the entire gene cluster, we show that the gene codes for a multifunctional locus. MATERIALS AND METHODS Fungal strains and culture conditions. m567, a wild-type strain from rice, was provided by the Fungal Culture Collection, Weimar, Germany.

Rationale: Hemophilia A is a rare X-linked hereditary bleeding disorder in which the secondary hemostasis is affected by a deficiency in clotting factor VIII (FVIII). As a consequence, patients may suffer from excessive bleeding in response to minor (surgical) trauma or injury. In all hemophilia A patients, perioperative factor concentrate replacement therapy is required, aiming for physiological FVIII plasma levels during up to 6 weeks. In mild hemophilia A patients, surgical procedures are the main reason for intensive treatment with FVIII concentrates. Treatment with FVIII concentrates is effective, but highly expensive. On average, treatment with FVIII concentrates costs 17,520 per mild hemophilia A patient, per surgical procedure. Moreover, exposure to exogenous FVIII may cause the development of FVIII neutralizing antibodies. Recent studies have shown this incidence is higher than realized previously. Neutralizing antibodies are a major challenge in hemophilia A patients, as they lead to ...

Dabigatran dosage varied on basis of renal function (300 mg twice daily in those with a CrCl of 110 ml per minute or more, 220 mg twice daily in those with a CrCl of 70 to 109 ml per minute, 150 mg twice daily in patients with a CrCl less than 70 ml per minute) ensuring a trough level of 50 ng/ml or higher. If the levels were insufficient on higher Dabigatran dose or CrCl was , 30 ml/min patients were switched to a non-study anticoagulant. In the Warfarin group, INR was targeted to be 2-3 for aortic mechanical valve with no additional risk factors and 3-3.5 for mitral mechanical valve or aortic valve with additional thrombotic risk factors ...
The use of surrogates either as native orthologous proteins or as optimized chimeras, which can be readily crystallized and soaked with small molecules, has been validated by its success in other fields, particularly in guiding kinase inhibitor development (Ikuta et al., 2001; Breitenlechner et al., 2004). One should bear in mind, however, that the surrogate approach has its limitations, and local structural differences may have considerable effect on ligand binding (Davies et al., 2007). HIV-1 and PFV INs are fully orthologous, with identical canonical domain folds and stoichiometry. Fortuitously, all intasome atoms (protein, DNA, metal ions) that are in contact with the soaked INSTI molecules are invariant between HIV-1 and PFV (Hare et al., 2010a). Thus, we expect that structural differences between HIV-1 and PFV intasomes that are directly relevant to INSTI binding will be small. An unbiased test of this idea can be made by comparing the active sites in isolated catalytic core domains from ...

Type and quantity of replacement treatment, together with haematological and immunological parameters were determined in 37 boys with severe haemophilia A and 41 children with other bleeding disorders. The quantity of factor VIII concentrate given to boys with severe haemophilia A (mean U/year) showed a significant inverse correlation with total white cell counts, lymphocyte counts, platelet counts, and the ratio of monoclonal antibody defined T lymphocyte subsets, T4 and T8 (T4:T8). Of the boys with severe haemophilia A, 49% had inversed T4:T8 ratios and 24% had thrombocytopenia. Treatment with high dose factor VIII concentrate (more than 25 000 U/year) was associated with low platelet counts, low lymphocyte counts, low T4:T8 ratios, and hypergammaglobulinaemia. In addition, six patients with severe haemophilia A and factor VIII inhibitors had inversed T4:T8 ratios. Patients treated exclusively with cryoprecipitate or prothrombin complex concentrates had normal T4:T8 ratios and platelet counts. ...
A carrier is a female who has the genetic mutation for hemophilia on one of her X chromosomes. Carriers with clotting factors levels of less than 50% of normal may have symptoms similar to a male with mild hemophilia. They are often called symptomatic carriers or are diagnosed with mild hemophilia. Approximately one-third of carriers experience bleeding symptoms. By definition, if a woman has clotting factor levels less than 50%, she has mild hemophilia.. Von Willebrand Disease (vWD), the most common inherited bleeding disorder in the US, and is a cause of heavy menstrual bleeding and other bleeding problems in women and adolescent girls. Women can also have other rare blood disorders like factor deficiencies I, II, V, VII, X, XI, XII, XIII and types of platelet disorders.. Bleeding disorders among females may cause special challenges because of the bleeding associated with menstruation and childbirth. Menorrhagia is abnormally heavy and prolonged menstrual period and is the most common symptom ...
In an article release by the CDC (Center for Disease Control and Prevention), research reports key findings related to the formation of inhibitors (antibodies) in patients who have hemophilia. The study shows that hemophilia A and hemophilia B patients who develop inhibitors are likely to have a specific type of antibody called immunoglobulin G subclass 4, or IgG4. In the event that traditional inhibitor tests do not provide clear results, testing for these antibodies instead may help clarify whether an inhibitor is present.. Inhibitors are antibodies (protein) that prevents or stops infused factor from working. For those with bleeding disorders like hemophilia A and hemophilia B, inhibitors often develop because the bodys immune system identifies the clotting factor as foreign. A blood test called Nijmegen-Bethesda Assay (NBA) is used to diagnose inhibitors.. For some cases, NBA can produce an unclear result as to whether a patient has an inhibitor or not. The CDC researchers have addressed ...

WHAT IS HEMOPHILIA?. Hemophilia is a rare bleeding disorder in which the blood doesnt clot normally.. After an injury, people with hemophilia do not bleed more or faster than people without hemophilia, but they do bleed longer. They also may bleed internally especially in the knees, ankles and elbows. This bleeding can cause damage to organs and tissues and may become life threatening.. Hemophilia is usually inherited and caused by the absence or inactivity of clotting factor. Clotting factor is a protein needed for normal blood clotting. There are several types of clotting factors, and they work with platelets to help form a clot. Platelets are small blood cell fragments that are formed in the bone marrow and play a major role in blood clotting. When blood vessels are injured, clotting factors help the platelets stick together to plug cuts and breaks to stop the bleeding. Without clotting factors, normal blood clotting cant take place.. There are two main types of hemophilia: A and B. If you ...

Complement C3 has been shown to mediate antigen uptake by professional APCs and presentation to CD4+ and CD8+ T cells.22 Therefore, we investigated the role of complement in the endocytosis and presentation of FVIII by human APCs in vitro. The use of heat-treated serum, wherein the complement system is inactivated, was associated with baseline levels of FVIII endocytosis by MO-DCs, as previously described.7,23,24 Similar levels of endocytosis were observed when the serum was immune depleted from the C3 component. In contrast, the use of normal serum that allows activation of complement leads to an increased uptake of FVIII in the case of both MO-DCs and circulating blood DCs. In line with these data, normal serum enhanced presentation of FVIII to an FVIII-specific T-cell hybridoma, as compared to serum lacking active C3. Since heating of serum may affect proteins other than complement, we reconstituted the C3-convertase in vitro using purified proteins. In vitro reconstitution of the ...
Long-lived plasma cells (LLPCs) can persistently produce anti-factor VIII (FVIII) antibodies which disrupt therapeutic effect of FVIII in hemophilia A individuals with inhibitors, The migration of plasma cells to BM where they become LLPCs is definitely largely handled by an interaction between the chemokine ligand CXCL12 and its receptor CXCR4. or intraperitoneally (i.g.) inserted with low dosage FVIII proteins (2U/mouse/wk; Kogenate?, Bayer (Whippany, Nj-new jersey)) consecutively for 4 weeks. 4-6 weeks after the intraperitoneal or hydrodynamic shot, plasma examples had been gathered for analyzing the inhibitor titers by Bethesda assay[31].

A rare condition in itself, acquired hemophilia A, seldom presents as isolated gross hematuria. It is a serious condition with a high mortality rate and thus clinical suspicion followed by prompt diagnosis is imperative (1). In fact, only 8 cases of such presentation of this condition have been reported thus far in the literature. Of these, none describe the initial presentation of hematuria with the inciting event of a kidney stone. We present a case of a 67-year-old man with signs and symptoms of nephrolithiasis accompanied by profuse hematuria, who was subsequently found to have developed expression of factor VIII inhibitor leading to acquired hemophilia A ...

John Pasi presented data from his experience with NuPreviq in "The NuPreviq Approach: Optimising PK-guided Personalised Prophylaxis with Nuwiq®", which described the efficacy & safety of personalised PK-based prophylaxis with Nuwiq® in adult PTPs with severe haemophilia A. He described how NuPreviq offers an effective approach to individualising therapy, presenting data that demonstrated excellent protection from ...

hemophilia: Any of several hereditary blood-coagulation disorders in which the blood fails to clot normally because of a deficiency or abnormality of one of the clotting factors. Hemophilia, a recessive trait associated with the X-chromosome, is manifested almost exclusively in males.
Press Release issued May 12, 2017: Hemophilia is a rare, inherited disorder in which blood doesnt clot normally due to the lack of sufficient blood clotting factor. Clotting factor is a protein required for blood clotting to occur normally. These proteins work with platelets i.e. small blood cell fragments that form in the bone marrow, to help the blood clot. Hemophilia is passed from parents to children through genes.
There is no direct benefit. The results of this study may help us learn if there are potential advantages of utilizing a patient-specific laboratory test called batch-selection to decrease the time to success in Immune Tolerance Induction (ITI) for hemophilia A patients with inhibitors to FVIII ...
Hemophilia A is an inherited, X-linked, recessive disorder caused by deficiency of functional plasma clotting factor VIII (FVIII). In a significant number of cases, the disorder results from a new mutation or an acquired immunologic process.

For 33-year-old videoeditor and hemophilia patient Travis Roop, being able to getlife-saving infusions of a blood clotting agent every two weeks,instead of rushing to treat a bleeding episode, meant he couldjog for the first time.
Hemophilia is not curable, but proper medical management of hemophilia can reduce the risk of bleeding as well as other co-morbidities.
The transfusion requirements of 75 adolescents with severe haemophilia A were studied during the five-year period 1973-77. The annual incidence of the 4935 episodes studied increased by a factor of 2.2 while the number of transfusions rose by a factor of 2.5 and the amount of therapeutic material used during the five years of the survey increased by a factor of 2.6. A further 166 bleeds occurred during periods of prophylaxis in 1976 and 1977, which generated a 25% increase in factor VIII used during those years. The increased usage of factor VIII in the years 1976 and 1977 was thus due mainly to increased numbers of transfusions given per bleed and to the use of prophylaxis but also to a slight increase in the units of factor VIII given in each dose. Twice weekly prophylaxis reduced the bleeding frequency by 30% and resulted in an increase of about 12% in usage of factor VIII. Prophylaxis given three times weekly reduced the bleeding frequency by about 60% at the cost of an increase of 77% in ...

Valder Arruda, M.D., Ph.D.. Our laboratory is interested in the development of gene-based strategies for the treatment of bleeding and thrombotic diseases. In a collaborative effort, we, along with others, have carried out early-phase clinical studies on adeno-associated viral (AAV) vectors for the treatment of severe hemophilia B (factor IX deficiency). Current projects are focused on translational research studies on the efficacy and safety of intravascular delivery of AAV vectors to skeletal muscle or liver of dogs and mice with severe hemophilia B and hemophilia A (factor VIII deficiency). We are developing novel variants of coagulation factor VIII or factor IX with enhanced biological activity to optimize gene and protein based strategies. We have identified a factor IX variant (FIX Padua) with 8-10-fold higher specific activity, and this molecule is now used for gene therapy in hemophilia B dog models.. Recently the focus of the laboratory has been on the use of gene therapy to treat a ...

Challenges and successes in the treatment of hemophilia: the story of a patient with severe hemophilia A and high-titer inhibitors Hussain I Saba, Duc Quang Tran, JrDepartment of Medicine, University of South Florida Medical Center, Tampa, FL, USAAbstract: In the past, patients with severe hemophilia have suffered a substantially reduced quality of life with frequent bleeding episodes, disabling arthropathy, and shorter life expectancy. In addition, methods of treatment and management have been costly and time-consuming, and have placed a considerable burden on patients' physical and psychological well-being. With the advent of the on-demand therapy and prophylactic treatment paradigm, patients have been able to receive care with less interruption of daily activities. Treatments may be more challenging for hemophiliacs with inhibitors to replacement factor; however, recent advances in the use of bypassing agents and immune tolerance therapy have enabled them to aggressively manage their disease
Hemophilia types A and B are inherited diseases passed on to children from a gene located on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. A female carrier of hemophilia has the hemophilia gene on one of her X chromosomes. When a hemophilia carrier female is pregnant, there is a 50/50 chance that the hemophilia gene will be passed on. If the gene is passed on to a son, he will have the disease. If the gene is passed on to a daughter, she will be a carrier. If the father has hemophilia but the mother does not carry the hemophilia gene, then none of the sons will have hemophilia disease, but all of the daughters will be carriers.. In about one-third of the children with hemophilia, there is no family history of the disorder. It is believed that, in these cases, the disorder could be related to a new gene mutation. Tests are available to possible carriers to help determine whether or not they, in fact, carry the abnormal gene.. Carriers of the ...

The 1-stage FVIII coagulant assay is the most widely used method for the determinations of the FVIII clotting activity because of its reproducibility, simplicity, and low cost. In many centers, particularly in Europe, use for the chromogenic assay to determine FVIII levels is more frequent. The results obtained with both assays usually correlate with each other. No significant differences in the results between the 2 methods have been detected in normal donors and in those with chronic liver disease (Chandler WL et al. Am J Clin Pathol 2003;120:34-39). However, discrepancies in the assays are observed in patients with mild hemophilia who have missense mutations (Verbruggen B et al. Haemophilia 2008;14(Suppl 3):76-82). Very low FVIII coagulant activities can sometimes be better diagnosed by a chromogenic assay ...
When most people get a cut, the body naturally protects itself. Sticky cells in the blood called platelets go to where the bleeding is and plug the hole. This is the first step in the clotting process. When the platelets plug the hole, they release chemicals that attract more sticky platelets and also activate various proteins in the blood known as clotting factors. These proteins mix with the platelets to form fibers, and these fibers make the clot stronger and stop the bleeding.. Our bodies have 12 clotting factors that work together in this process (numbered using Roman numerals from I through XII). Having too little of factors VIII (8) or IX (9) is what causes hemophilia. A person with hemophilia will lack only one factor, either factor VIII or factor IX, but not both. There are two major kinds of hemophilia: hemophilia A, which is a factor VIII deficiency; and hemophilia B, which is a factor IX deficiency.. People with hemophilia may bruise and bleed easily, and they may bleed a lot or for ...

Consumer Medicine Information (CMI) about Xyntha (moroctocog alfa rch, also known as recombinant coagulation factor VIII) intended for persons living in Australia.
Hemophilia is a genetically inherited bleeding disorder. There are two types of hemophilia: hemophilia A, or clotting factor VIII deficiency, and hemophilia B, or clotting factor IX deficiency. The degree of deficiency varies from mild to severe. About one third of hemophilia cases occur with no previous family history; this is called sporadic hemophilia. It is assumed that these cases are the result of genetic mutation.
Introduction Despite the advent of extended half-life factor IX (FIX) products with the potential for 14 days or longer prophylactic dosing in patients with severe hemophilia B, long-term data on the use of ≥14-day dosing are lacking for prolonged periods of observation. A post hoc analysis of the B-LONG Phase 3 trial showed that ~50% of subjects in the individualized interval prophylaxis treatment arm (Arm 2, n=29) used extended dosing intervals (≥14 days) and had low annualized bleed rates (ABRs) that were similar to ABRs in subjects on other dosing intervals in Arm 2.1. The purpose of this analysis was to evaluate whether sustained ≥14-day dosing with recombinant FIX Fc fusion protein (rFIXFc) can provide safe and effective protection from bleeding in selected patients with severe hemophilia B over time in a near real-world setting. Methods B-LONG (NCT01027364) enrolled 123 adults and adolescents ≥12 years of age into 1 of 4 treatment arms: weekly prophylaxis (50 IU/kg every 7 days, ...
Published February 2014. ISBN: 978-1-78084-444-2. Hemophilia is an age-old disease, but the distinction between hemophilia A and B was not made until the 1940s and 1950s. At that time, it was a disease with a very poor prognosis with an expected median survival of little more than 10 years. Since then, evolution of the understanding of the disease and treatment has been explosive. In this book, hemophilia is addressed from both a basic science and a practical perspective. The eight chapters are written by some of the most distinguished hemophilia experts in the world, sometimes in collaboration with members of the next generation of professionals. The content is up to date, reliable and written in a manner that will engage and educate less-experienced staff at hemophilia treatment centers and hematology departments to promote the development of care in hemophilia. The book will also interest professionals from related disciplines, together with students and administrators.. ...
Hemophilia is a rare genetic bleeding disorder that causes the blood to take a long time to clot as a result of a deficiency in one of several blood clotting factors, and occurs almost exclusively in males. People with hemophilia face specific risks as they are not able to form blood clots efficiently and are at risk for excessive and recurrent bleeding from modest injuries, which have the potential to be life threatening. People with severe hemophilia often bleed spontaneously into their muscles or joints. The incidence of hemophilia B is one in 25,000 male births. People with hemophilia B have a deficiency in clotting factor IX, a specific protein in the blood. Hemophilia B is also called congenital factor IX deficiency or Christmas disease. Current standard of care requires recurrent intravenous infusions of either plasma-derived or recombinant factor IX to control and prevent bleeding episodes. There exists a significant need for novel therapeutics to treat people living with ...

The most common symptom of this disorder is heavy, uncontrollable bleeding. The severity of hemophilia depends on the amount of clotting factors in the blood. Those affected with hemophilia that have levels greater than 5% (100% being average for unaffected children) most often have bleeding only with major surgeries or tooth extractions. These children may not even be diagnosed until bleeding complications from a surgery occur.. Severe hemophilia is when the factor VIII or IX is less than 1%. Bleeding can occur in these children, even with the minimal activities of daily life. Bleeding may also occur from no known injury. Bleeding most often occurs in the joints and in the head.. Your childs symptoms may also include:. ...

Hemophilia treatments: Hemophilia is a genetic disease in which people (almost all men) lack the ability to clot blood. To control the condition, hemophiliacs take Factor VIII, a clotting factor. Each dose of Factor VIII comes from the pooled blood of many donors. Currently, over 90% of hemophiliacs in the U.S. have been infected with HIV because of receiving contaminated Factor VIII in the early years of the epidemic. Factor VIII is now heat-treated to kill the virus. In addition, there are new synthetic products that do not pose any risk for HIV and which accomplish the same function ...

Lawandi, A. Diss. Concordia University, 2014. The neurohypophysis is known to secrete vasopressin during times of severe haemorrhage, and oxytocin during labour and delivery, events in which blood loss also occurs. Evidence suggests that there may be an interaction between these peptides and the coagulation cascade, and currently, desmopressin, a drug analog of vasopressin, is a first line therapy for mild Hemophilia A, a common coagulopathy. In this work, interactions between vasopressin and oxytocin with a crucial member of the coagulation cascade, the cofactor Factor VIII, were investigated using fluorescence spectroscopy, interference immunoassays, commercially produced Factor VIII activity kits, and equilibrium dialysis. The results suggest not only that the peptides interact with the coagulation factor, but do so in a way that enhances its activity and prolongs its active form half-life, as seen through the enhancement of the activity of the FXase complex by assay. This theory was then ...
LONDON - Hemophilia is the most common type of inherited bleeding disorder in which a person lacks or has reduced levels of specific proteins termed clotting factors and the blood does not clot in a proper way, which leads to excessive bleeding.. People with this condition experience continuous bleeding or oozing after an injury, surgical operation, or following tooth extraction. In severe cases, prolonged bleeding takes place after minor injury or even when there is not any injury (spontaneous bleeding). Severe complications can stem from bleeding into the joints, muscles, or other internals.. There are 3 forms of hemophilia, namely A, B, and C. Hemophilia A is the most typical form of the disease, which results from a deficiency in factor VIII. 8 out of 10 people with hemophilia have hemophilia A. Hemophilia B (otherwise termed Christmas disease) is caused by factor IX a deficiency. Hemophilia C is caused by a deficiency of factor XI, and is mild and rare form of hemophilia in which ...
CH8 : Factor VIII (FVIII) is synthesized in the endothelial cells of the liver, and perhaps in other tissues. It is a coagulation cofactor that circulates bound to von Willebrand factor and is part of the intrinsic coagulation pathway. The biological half-life is 9 to 18 hours (average is 12 hours).   Congenital FVIII deficiency results in hemophilia A, which has an incidence of 1 in 10,000 live male births, and is inherited in a recessive X-linked manner. Patients with severe deficiency (<1%) experience spontaneous bleeding episodes (eg, hemarthrosis, deep-tissue bleeding, etc), whereas patients with moderate or mild deficiency (>1%) typically experience posttrauma or surgical bleeding.   FVIII activity assays (FVIII:C) are performed to diagnose hemophilia A and to monitor FVIII replacement therapy. FVIII:C assays are typically 1-stage clotting assays. However, there is a subset of mild hemophilia A patients who have shown discrepantly low results when measured with the 2-stage

  • Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood. (wikipedia.org)
  • While traditional thromboelastography is a global assay for blood clotting disorders and drug effects, TEM is primarily used in combination with appropriate differential assays. (wikipedia.org)
  • This unit discusses the general categories of proteases, and sets the stage for addition of overview units on cysteine proteases, aspartic proteases, and metalloproteases, as well as protocol units featuring techniques for analyzing mammalian and yeast proteasomes and protease inhibitors, among other topics. (currentprotocols.com)
  • The purpose of this study is to determine if TAK-442, once daily (QD) or twice daily (BID), is as safe and effective as enoxaparin in preventing the development of blood clots after knee replacement surgery. (clinicaltrials.gov)
  • Davie EW, Ratnoff OD (1964) Waterfall sequence for intrinsic blood clotting. (springer.com)
  • In addition to the theoretical considerations involving the reactions of the tissue factor pathway, a physical constraint associated with the stability of the factor VIIIa-factor IXa complex has been incorporated into the model based upon the empirical observations associated with the stability of this complex. (omicsdi.org)
  • The model is responsive to alterations in the concentrations of factor VIII, factor V, and their respective activated species, factor VIIIa and factor Va, and overall provides a reasonable approximation of empirical data. (omicsdi.org)
  • However, in previously reported pharmacokinetic/pharmacodynamic (PK/PD) models, the complex coagulation processes and detailed information of drug action are usually unclear, which makes it difficult to predict clinical outcome at the drug discovery stage. (omicsdi.org)
  • As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria. (bioportfolio.com)
  • The adjusted OR for major cardiovascular risk factors was 2.569 (95% CI 1.086-6.074). (cdc.gov)
  • Factor Xa (FXa) emerged as a promising target for effective anticoagulation and several FXa inhibitors are now available for the prevention of venous thromboembolism. (omicsdi.org)

  • The contribution of prothrombotic genetic risk factors in the pathogenesis of premature acute myocardial infarction (MI) is controversial. (cdc.gov)
  • Prothrombotic genetic risk factors in patients with very early ST-segment elevation myocardial infarction. (cdc.gov)
  • Following injury to the endothelium and vessel wall, a series of molecular and cellular events occur leading to the formation of a blood clot. (bloodjournal.org)
  • Inhibition of factor Xa (FXa) attenuates thrombus progression. (aspetjournals.org)
  • 4 , 5 Their results were consistent with the above cell-based model but further showed that TF and fibrin were initially localized to the vessel wall-thrombus interface and subsequently propagated through the thrombus by accumulation of blood-borne TF-bearing microparticles derived from leukocytes. (bloodjournal.org)
  • Treatment of anhepatic pigs with the AMC-BAL based on freshly isolated porcine hepatocytes does not result in an improved coagulation state due to extensive consumption of clotting factors. (nih.gov)
  • Several reports confirm that application of TEM is cost effective by reducing the consumption of blood products. (wikipedia.org)
  • In the vascular area a new group of drugs, the renin inhibitors, is likely to emerge for the treatment of hypertension. (springer.com)
  • Published English-language studies that had at least 10 patients in the treatment group, used convalescent blood products to treat Spanish influenza pneumonia in a hospital setting, and reported on a control or comparison group. (annals.org)
  • Treatment of anhepatic pigs with the cell-loaded BAL did not restore PT or clotting factor levels. (nih.gov)
  • Other Xa inhibitors advantages are rapid onset/offset, few drug interactions and predictable pharmacokinetics. (wikipedia.org)
  • The signal of the pin suspended in the blood sample is transmitted via an optical detector system. (wikipedia.org)
