Sperm chemotaxis. (1/874)

Communication between spermatozoa and egg before contact by chemotaxis appears to be prevalent throughout the animal kingdom. In non-mammalian species, sperm chemotaxis to factors secreted from the egg is well documented. In mammals, sperm chemotaxis to follicular factors in vitro has been established in humans and mice. The attractants of female origin in non-mammalian species are heat-stable peptides or proteins of various sizes, or other small molecules, depending on the species. Species specificity of the attractants in non-mammalian species may vary from high species specificity, through specificity to families with no specificity within a family, to absence of specificity. The mammalian sperm attractants have not been identified but they appear to be heat-stable peptides. The claim that progesterone is the attractant for human spermatozoa has failed to be substantiated, neither have claims for other mammalian sperm attractants been verified. The molecular mechanism of sperm chemotaxis is not known. Models involving modulation of the intracellular Ca2+ concentration have been proposed for both mammalian and non-mammalian sperm chemotaxis. The physiological role of sperm chemotaxis in non-mammalian species appears to differ from that in mammals. In non-mammalian species, sperm chemotaxis strives to bring as many spermatozoa as possible to the egg. However, in mammals, the role appears to be recruitment of a selective population of capacitated ('ripe') spermatozoa to fertilize the egg.  (+info)

Age-related changes in blood coagulation and fibrinolysis in mice fed on a high-cholesterol diet. (2/874)

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.  (+info)

Single and combined prothrombotic factors in patients with idiopathic venous thromboembolism: prevalence and risk assessment. (3/874)

The inherited thrombophilias--deficiencies of protein C, protein S, and antithrombin III--and the prothrombotic polymorphisms factor V G1691A and factor II G20210A predispose patients toward venous thromboembolism (VTE). The aim of this study was to determine the prevalence of single and combined prothrombotic factors in patients with idiopathic VTE and to estimate the associated risks. The study group consisted of 162 patients referred for work-up of thrombophilia after documented VTE. The controls were 336 consecutively admitted patients. In all subjects factor V G1691A, factor II G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T were analyzed by specific polymerase chain reactions and restriction enzymes. Activities of antithrombin III and protein C, free protein S antigen, and lupus anticoagulant were determined in a subset of 109 patients who were not receiving oral anticoagulants. The prevalences of heterozygotes and homozygotes for factor V G1691A and factor II G20210A among patients and controls were 40.1% versus 3.9% and 18.5% versus 5.4%, respectively (P=0.0001). The prevalence of homozygotes for MTHFR C677T in patients was 22.8% and in controls, 14.3% (P=0.025). Heterozygous and homozygous factor V G1691A, factor II G20210A, and homozygous MTHFR C677T were found to be independent risk factors for VTE, with odds ratios of 16.3, 3.6, and 2.1, respectively. Two or more polymorphisms were detected in 27 of 162 patients (16.7%) and in 3 of 336 controls (0.9%). Logistic regression analysis disclosed odds ratios of 58.6 (confidence interval [CI], 22.1 to 155.2) for joint occurrence of factor V and factor II polymorphisms, of 35.0 (CI, 14.5 to 84.7) for factor V and MTHFR polymorphisms, and of 7.7 (CI, 3.0 to 19.6) for factor II and MTHFR polymorphisms. Among 109 patients in whom a complete thrombophilic work-up was performed, 74% had at least 1 underlying defect. These data indicate that in most patients referred for evaluation of thrombophilia due to idiopathic VTE, 1 or more underlying genetic predispositions were discernible. The presence of >1 of the prothrombotic polymorphisms was associated with a substantial risk of VTE.  (+info)

Oxidation of methionine residues in antithrombin. Effects on biological activity and heparin binding. (4/874)

Commercially available human plasma-derived preparations of the serine protease inhibitor antithrombin (AT) were shown to contain low levels of oxidation, and we sought to determine whether oxidation might be a means of regulating the protein's inhibitory activity. A recombinant form of AT, with similarly low levels of oxidation as purified, was treated with hydrogen peroxide in order to study the effect of oxidation, specifically methionine oxidation, on the biochemical properties of this protein. AT contains two adjacent methionine residues near the reactive site loop cleaved by thrombin (Met314 and Met315) and two exposed methionines that border on the heparin binding region of AT (Met17 and Met20). In forced oxidations with hydrogen peroxide, the methionines at 314 and 315 were found to be the most susceptible to oxidation, but their oxidation did not affect either thrombin-inhibitory activity or heparin binding. Methionines at positions 17 and 20 were significantly oxidized only at higher concentrations of peroxide, at which point heparin affinity was decreased. However at saturating heparin concentrations, activity was only marginally decreased for these highly oxidized samples of AT. Structural studies indicate that highly oxidized AT is less able to undergo the complete conformational change induced by heparin, most probably due to oxidation of Met17. Since this does not occur in less oxidized, and presumably more physiologically relevant, forms of AT such as those found in plasma preparations, oxidation does not appear to be a means of controlling AT activity.  (+info)

Dose response of intravenous heparin on markers of thrombosis during primary total hip replacement. (5/874)

BACKGROUND: Thrombogenesis in total hip replacement (THR) begins during surgery on the femur. This study assesses the effect of two doses of unfractionated intravenous heparin administered before femoral preparation during THR on circulating markers of thrombosis. METHODS: Seventy-five patients undergoing hybrid primary THR were randomly assigned to receive blinded intravenous injection of either saline or 10 or 20 U/kg of unfractionated heparin after insertion of the acetabular component. Central venous blood samples were assayed for prothrombin F1+2 (F1+2), thrombin-antithrombin complexes (TAT), fibrinopeptide A (FPA), and D-dimer. RESULTS: No changes in the markers of thrombosis were noted after insertion of the acetabular component. During surgery on the femur, significant increases in all markers were noted in the saline group (P < 0.0001). Heparin did not affect D-dimer or TAT. Twenty units per kilogram of heparin significantly reduced the increase of F1+2 after relocation of the hip joint (P < 0.001). Administration of both 10 and 20 U/kg significantly reduced the increase in FPA during implantation of the femoral component (P < 0.0001). A fourfold increase in FPA was noted in 6 of 25 patients receiving 10 U/kg of heparin but in none receiving 20 U/kg (P = 0.03). Intraoperative heparin did not affect intra- or postoperative blood loss, postoperative hematocrit, or surgeon's subjective assessments of bleeding. No bleeding complications were noted. CONCLUSIONS: This study demonstrates that 20 U/kg of heparin administered before surgery on the femur suppresses fibrin formation during primary THR. This finding provides the pathophysiologic basis for the clinical use of intraoperative heparin during THR.  (+info)

Effect of thrombin inhibition in vascular dementia and silent cerebrovascular disease. An MR spectroscopy study. (6/874)

BACKGROUND AND PURPOSE: Silent cerebrovascular disease (CVD) has been proposed as a predisposing condition for clinically overt stroke and vascular dementia. Recently, we found increased thrombin generation in silent CVD patients. Here, we report the effect of thrombin inhibition using a potent selective thrombin inhibitor on the cerebral metabolism and function in peripheral arterial occlusive disease (PAOD) patients with or without silent CVD. METHODS: We examined 17 mild chronic PAOD patients, including 2 cases of vascular dementia. We divided the patients into 2 groups: 1 was the advanced CVD group with multiple lacunar infarction and/or advanced periventricular hyperintensity detected by brain MRI (n=12), and the other was the no CVD group that had none of these abnormalities (n=5). We assessed the cerebral biochemical compounds in the deep white matter area and cerebellar hemisphere (8 cm3) by proton MR spectroscopy before and after infusion of argatroban (10 mg/d IV) over 2 hours for 7 days. RESULTS: The ratio of N-acetylasparate (NAA) to total creatine (Cre) in the deep white matter area was significantly lower in the advanced CVD group than in the no CVD group, whereas there were no significant differences in this ratio in the cerebellar hemisphere between the 2 groups. In the former group, this decreased NAA/Cre ratio significantly increased after argatroban therapy, whereas there was no change in the latter group. The 2 patients with vascular dementia showed clinical improvement with marked increases in the NAA/Cre ratio and mini-mental score. CONCLUSIONS: These results suggest that increased thrombin generation may have some pathophysiological roles in developing vascular dementia and its chronic predisposing conditions. Thrombin inhibition may break this vicious cycle and lead to clinical improvement.  (+info)

Comparison of the antithrombotic effect of PEG-hirudin and heparin in a human ex vivo model of arterial thrombosis. (7/874)

Polyethylene glycol (PEG)-hirudin is a derivative of hirudin with a long plasma half-life. We have compared the efficacy of PEG-hirudin with unfractionated heparin (UH) in preventing arterial thrombosis. Arterial thrombus formation was induced ex vivo in 12 healthy human volunteers by exposing a tissue factor-coated coverslip positioned in a parallel-plate perfusion chamber to flowing nonanticoagulated human blood drawn directly from an antecubital vein at an arterial wall shear rate of 2600 s-1 for 3.5 minutes. PEG-hirudin, UH, or saline (as control) were administered ex vivo through a heparin-coated mixing device positioned proximal to the perfusion chamber. Platelet and fibrin deposition was quantified by immunoenzymatic measure of the P-selectin and D-dimer content of dissolved plasmin-digested thrombi, respectively. UH was administered to a plasma concentration of 0.35 IU/mL. This concentration prolonged the activated partial thromboplastin time from 32+/-1 seconds to 79+/-4 seconds (P<0.01). UH did not significantly prevent platelet deposition. However, fibrin deposition was reduced by 39% (P<0.05). PEG-hirudin in plasma concentrations of 0.5, 2.5, and 5 microg/mL prolonged the activated partial thromboplastin time to 48+/-2, 87+/-4, and 118+/-4 seconds, respectively. In contrast to UH, PEG-hirudin prevented both platelet and fibrin deposition in a dose-dependent manner with a >80% reduction at 5 microg/mL (P<0.01). Furthermore, the plasma level of PEG-hirudin required to significantly prevent fibrin deposition (0.5 microg/mL) corresponded to a much shorter prolongation of activated partial thromboplastin time (48+/-2 seconds) than that needed for UH (79+/-4 seconds). Thus, our results are compatible with the view that thrombin is greatly involved in recruitment of platelets in evolving thrombi, and that PEG-hirudin is an effective agent for preventing arterial thrombosis in a human ex vivo experimental model.  (+info)

Prognostic significance of elevated hemostatic markers in patients with acute myocardial infarction. (8/874)

OBJECTIVES: The purpose of this study was to determine whether the elevated levels of hemostatic markers in the early phase of myocardial infarction may serve as risk factors for subsequent cardiac mortality. BACKGROUND: Increased plasma hemostatic markers were noted in acute myocardial infarction, indicating that the blood coagulation system is highly activated in those patients. However, there are few clinical data concerning the association between the elevated hemostatic markers and survival in patients with myocardial infarction. METHODS: Blood samples were obtained from 64 patients (mean age 67 +/- 11 years; 49 male) with acute myocardial infarction within 12 h after the onset of symptoms and before the initiation of any antithrombotic treatment. We measured plasma concentrations of fibrinopeptide A (FPA), prothrombin fragment 1+2 (F1+2) and thrombin-antithrombin complex (TAT) using the enzyme-linked immunosorbent assay method, and examined the associations between the level of these markers and survival with Cox proportional hazards models. RESULTS: The follow-up time was 27 +/- 17 months, and 19 patients died of cardiac causes during the follow-up. Univariate survival analysis identified Killip class IV (hazard ratio 4.86; 95% confidence interval [CI] 1.55-15.19), left ventricular ejection fraction (hazard ratio 0.94; 95% CI 0.90-0.99), FPA (hazard ratio 1.54; 95% CI 1.13-2.10), F1+2 (hazard ratio 2.03; 95% CI 1.17-3.53) and TAT (hazard ratio 1.88; 95% CI 1.27-2.79) as significant factors associated with cardiac mortality. In multivariate analyses, only FPA level (hazard ratio 1.84; 95% CI 1.03-3.30) and left ventricular ejection fraction (hazard ratio 0.93; 95% CI 0.88-0.98) were independent predictors of cardiac mortality. CONCLUSIONS: Elevated FPA in the early phase of myocardial infarction identifies patients with increased risk for subsequent cardiac death. This association appears to be independent of residual left ventricular function after infarction.  (+info)

N2 - An asymmetric triangular Fe111 complex has been synthesized by an unusual Fe11-promoted activation of salicylaldoxime. Formation of tile ligand 2(bis(salicylideneamino)methyl)phenol in situ is believed to occur through the reductive deoximation of salicylaldoxime by ferrous ions. The trinuclear ferric complex has been characterized on the basis of elemental analysis. IR, variable-temperature magnetic susceptibility, and EPR and Mossbauer spectroscopies. The molecular structure established by X-ray diffraction consists of a trinuclear structure with a [Fe3(μ3-O)(μ2-OPh]61 core. Two iron ions are in a distorted octahedral environment having FEN2O4 coordination spheres, ...
Abstract. Human antithrombin III (ATIII) is a plasma inhibitor of several serine proteases of the blood coagulation system. Previous investigations have report
The new heparins are prepared from unfractionated heparin by enzymatic or chemical depolymerisation methods. The fractions have a mean molecular weight of 4000-6000 IU (range 1000-10000) compared with heparin which has a mean molecular weight of 15000 IU (range 5000-30000)1, hence the term low molecular weight heparin (LMWH). The antithrombotic effect of heparin is achieved through its interaction with plasma antithrombin III which accelerates the inactivation of the coagulation enzymes thrombin (Factor IIa), Factor Xa and Factor IXa. Thrombin is inactivated only when it is bound to both antithrombin III and heparin.2 Heparin fragments can only bind to antithrombin III and thrombin when they exceed a molecular weight of 5000 IU. Fragments of smaller size (LMWHs) cannot bind to antithrombin III and thrombin, but can bind to antithrombin III and Factor Xa. This catalyses the inactivation of Factor Xa. The LMWHs presently marketed in Australia are dalteparin, enoxaparin and nadroparin. These are ...
Background: Antithrombin III is known as the most important natural inhibitor of thrombin activity and has been shown to attenuate local harmful effects of ischemia-reperfusion injury in many organs. In recent animal studies, delaying effect of remote organ ischemia-reperfusion injury on healing of intestinal anastomoses has been demonstrated. In this study, we investigated whether antithrombin III reduces deleterious systemic effects of ischemia-reperfusion injury on healing of colonic anastomoses in rats. ...
This study is the first to evaluate the long-term prognostic significance of hemostatic factor measurements in patients with angina pectoris and known coronary angiographic status. The clinical follow-up spanned 9.5 years, and complete follow-up information was available for 93% of the 225 patients initially recruited to the study. Although the number of patients investigated was comparatively small, the 58 patients with cardiac events, who represented more than a quarter of the original patient sample, allowed meaningful conclusions on risk relationships with hemostatic and angiographic baseline variables. Some earlier cross-sectional studies have indicated lower antithrombin III antigen or activity in patients with CAD compared with individuals without,32 33 34 35 while others have reported higher rather than lower values.36 37 In contrast, more recent investigations in large populations or patient cohorts failed to demonstrate an association of antithrombin III with the prevalence or extent ...

Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. The results for both activity and antigen tests are given as percentages. Different labs use slightly different normal ranges, but in general, 80% to 120% is considered normal for adults. Newborns usually have about half as much antithrombin as adults. Thrombin levels in infants rise to adult levels by about 6 months of age. People with genetically inherited antithrombin deficiency typically have test results between 40% and 60%. In both type 1 and type 2 AT deficiency, the antithrombin activity test shows a low result because you dont have as much working antithrombin as you should have. When the AT activity test shows that levels are low, the antithrombin antigen test can then be used to find out whether the deficiency is type 1 or type 2. If the follow-up ...

Displacement by plasma of radiolabeled thrombin and radiolabeled thrombin-antithrombin III inactive complex from a heparinized surface (heparin-PVA) was measured and found to be significant. For example, 63% of the thrombin and 90% of the complex that could not be removed by PBS alone was displaced by heat defibrinated plasma. Preliminary characterization (molecular weight, antithrombin III content) suggests that the eluting product consists largely of thrombin-antithrombin III complex and post complex antithrombin III. Heparin polyvinyl alcohol (PVA) gel beads were prepared by acetal coupling of the heparin to PVA using glutaraldehyde with MgCl2 catalysis. Although permanently bound to the PVA (heparin removal rate was 1.67 × 10-2 mg/g gel⋅min), the heparin retained at least part of its activity in thrombin time, recalcification time, chromogenic substrate and AV shunt assays. Thus, heparin need not be lost from a surface to impart thromboresistance. Our results further suggest that the ...

Compound:. Unfractionated heparin (UFH). Indications:. Heparin is preferred over warfarin in cases where it is necessary that the anticoagulant effect begins immediately. Its used to prevent deep vein thrombosis, pulmonary embolism and acute coronary syndromes.. Mechanism of action:. Antithrombin III is an endogenous molecule that inhibits factors II, IX, X, XI and XII and therefore the formation of fibrin. Heparin is a drug that increases the effect of antithrombin III and therefore has strong anticoagulant activity.. Heparin isnt actually a single molecule but a family of large and sulphated glycosaminoglycans that all act on antithrombin III. Heparin is actually present endogenously in the body inside the granules of mast cells. To acquire heparin the pharmaceutical industry extracts them from beef lung or pig intestine. However, because heparin isnt a single molecule can the biological activity of it differ depending on where it is extracted from. Because of this the dose of heparin is ...
Antithrombin is a protein in the blood that helps regulate blood clot formation. Antithrombin testing is used to investigate the cause of recurrent blood clot formation (such as DVT) and to identify an antithrombin deficiency.
METHODS AND RESULTS Fifty-five patients were treated with urokinase-preactivated prourokinase (n = 35) or tissue-type plasminogen activator (n = 20) for acute myocardial infarction and underwent coronary angiography at 90 minutes and at 24-36 hours into thrombolysis, and fibrinogen (Ratnoff-Menzie), D-dimer (ELISA) and thrombin-antithrombin III complex levels (ELISA) were measured. Primary patency was achieved in 39 patients (70.9%), 13 of whom (33.3%) suffered early reocclusion. Nonsignificant decreases in fibrinogen levels were observed while D-dimer levels increased +3,008 +/- 4,047 micrograms/l (p less than 0.01), differences not being significant in respect to the thrombolytic agents or to the clinical course. In contrast, while thrombin-antithrombin III complex levels decreased -4.4 +/- 13.0 micrograms/l in patients with persistent patency, they increased +7.5 +/- 13.6 micrograms/l in case of nonsuccessful thrombolysis (p less than 0.02) and +11.9 +/- 23.8 micrograms/l in case of early ...
Antithrombin III (AT III) supplementation has proven to be effective in the treatment of disseminated intravascular coagulation. According to the study by the Kumamoto University School of Medicine , administration of AT III is also useful for prevention of organ failure in animals challenged with endotoxin or bacteria and it increases the survival rate of such animals. Since inhibition of coagulation abnormalities failed to prevent organ failure in animals given bacteria, AT III may exert a therapeutic effect independent of its anticoagulant effect. This therapeutic mechanism of AT III has been explored using an animal model of septicemia. AT III prevented pulmonary vascular injury by inhibiting leukocyte activation in rats given endotoxin. This effect is mediated by the promotion of endothelial release of prostacyclin which inhibits leukocyte activation. Interaction of AT III with heparin-like glycosaminoglycans (GAGs) on the endothelial cell surface appears to be important for this effect. ...
The use of mouse models for the study of thrombotic disorders has gained increasing importance. Methods for measurement of coagulation activation in mice are, however, scarce. The primary aim of this study was to develop a specific mouse thrombin-antithrombin (TAT) ELISA for measurement of coagulation activation and to compare it with two commercially available assays for human TAT complexes. In addition, we aimed to improve methods for mouse plasma anticoagulation and preparation. First, for the measurement of TAT-complexes in plasma a mouse specific TAT-ELISA was developed using rabbit polyclonal antibodies raised against mouse thrombin and rat antithrombin, respectively. This ELISA detected an increase in TAT levels in a mouse model of endotoxemia. Two commercial human TAT ELISAs appeared to be less specific for mouse thrombin-rat antithrombin complexes. Second, to prevent clotting of mouse blood sodium citrate was either mixed with blood during collection in a syringe or was injected intravenously
Fondaparinux (trade name Arixtra) is an anticoagulant medication chemically related to low molecular weight heparins. It is marketed by GlaxoSmithKline. A generic version developed by Alchemia is marketed within the US by Dr. Reddys Laboratories. Fondaparinux is a synthetic pentasaccharide factor Xa inhibitor. Apart from the O-methyl group at the reducing end of the molecule, the identity and sequence of the five monomeric sugar units contained in fondaparinux is identical to a sequence of five monomeric sugar units that can be isolated after either chemical or enzymatic cleavage of the polymeric glycosaminoglycans heparin and heparin sulfate (HS). Within heparin and heparin sulfate this monomeric sequence is thought to form the high-affinity binding site for the anti-coagulant factor antithrombin III (ATIII). Binding of heparin/HS to ATIII has been shown to increase the anti-coagulant activity of antithrombin III 1000 fold. In contrast to heparin, fondaparinux does not inhibit thrombin. ...

heparin when studied with both thrombin and Xa incubation mixtures in purified mixtures. The inhibition of thrombin by heparin fractions and antithrombin III was unaffected by other plasma components. However, normal human plasma contained a component that inhibited the heparin and antithrombin III inhibition of Xa, particularly when the high MW heparin fraction was used. Experiments using a purified preparation of platelet factor 4 suggested that this platelet derived heparin neutralising protein was not responsible for the inhibition and that a hitherto undescribed inhibitor of heparin action is present in plasma. Preliminary studies have indicated that the inhibitor is concentrated in a fraction rich in lipoprotein and obtained by ultracentrifugation of plasma in high density salt ...
Preferred Name: Tinzaparin Sodium Definition: The sodium salt of a low molecular weight heparin (LMWH), obtained by controlled enzymatic depolymerization of heparin from porcine intestinal mucosa, with antithrombotic properties. Tinzaparin is a potent inhibitor of several activated coagulation factors, especially Factors Xa and IIa (thrombin); its primary activity is mediated through the plasma protease inhibitor antithrombin. In addition, this agent may inhibit angiogenesis through: 1) competitive binding of the heparin-binding sites on endothelial cells for the proangiogenic cytokines vascular endothelial growth factor (VEGF) and beta-fibroblast growth factor (beta-FGF) and 2) increasing the release of tissue factor pathway inhibitor (TFPI), a negative regulator of angiogenesis.

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a plasma protease inhibitor and a member of the serpin superfamily. This protein inhibits thrombin as well as other activated serine proteases of the coagulation system, and it regulates the blood coagulation cascade. The protein includes two functional domains: the heparin binding-domain at the N-terminus of the mature protein, and the reactive site domain at the C-terminus. The inhibitory activity is enhanced by the presence of heparin. More than 120 mutations have been identified for this gene, many of which are known to cause antithrombin-III deficiency.

TatA, TatB and TatC compose Tat complex on inner membrane. Tat complex recognizes TorA signal peptide and then it transports proteins (with TorA) from cytoplasm to periplasm with maintaining their folding. In short, proteins secreted via Tat pathway can keep active. In this experiment, we wanted to design a applicable TorA signal device to meet various needs and to check the function of signal sequence.

Antithrombin III deficiency (abbreviated ATIII deficiency) is a deficiency of antithrombin III. It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism, and repetitive intrauterine fetal death (IUFD). Inheritance is usually autosomal dominant, though a few recessive cases have been noted. The disorder was first described by Egeberg in 1965. The patients are treated with anticoagulants or, more rarely, with antithrombin concentrate. In kidney failure, especially nephrotic syndrome, antithrombin is lost in the urine, leading to a higher activity of Factor II and Factor X and in increased tendency to thrombosis. Heparin enhances ATIII activity and neutralizes activated serine protease coagulation factors. Patients with ATIII deficiency requiring anticoagulant therapy with heparin will need higher doses of heparin. ATIII binds to thrombin and then forms the thrombin-anti thrombin complex or TAT complex. This is a ...

A method for the differential determination of plasma antithrombins, antithrombin III and alpha2 macroglobulin, is described. The method is based on the selective inactivation of plasma alpha2 macroglobulin by treatment with 0-1 M methylamine for 10 minutes at 37 degrees C and on the observation that antithrombin III and alpha2 macroglobulin inhibited in defibrinated plasma low concentrations of thrombin without mutual interference and according to pseudo-first order reaction. In healthy subjects antithrombin III was shown to account for about 70% of the total antithrombin activity. But in patients with liver cirrhosis, where low levels of total antithrombin activity were observed, the relative contribution of antithrombin III was found to be noticeably lower.. ...

Antithrombin is a circulating plasma protein that functions as an important regulator of blood coagulation. It inactivates several enzymes of the coagulation cascade, in particular thrombin and factor Xa. Since a link between hereditary antithrombin deficiency and thrombosis was established in 1965, there has been increasing clinical interest in antithrombin and a need for simple and accurate determination. Assays based on chromogenic peptide substrates are now available, allowing photometric detection of antithrombin activity in plasma.. Thrombin is the key enzyme in blood coagulation. It clots blood by converting fibrinogen into clot-forming fibrin monomers and activates factor XIII leading to the strengthening of the blood clot by cross-linking. Thrombin also activates platelets and the cofactors, factor V and factor VIII, thereby accelerating its own generation and providing a quick response to injury. However, the autocatalytic nature of thrombin also entails certain hazards. The complete ...
Blood clot prevention and treatment reduces the risk of stroke, heart attack and pulmonary embolism. Heparin and warfarin are often used to inhibit the formation and growth of existing thrombi; the former binds to and activates the enzyme inhibitor antithrombin III, while the latter inhibits vitamin K epoxide reductase, an enzyme needed to synthesize mature clotting factors.. Some treatments have been derived from bacteria. One drug is streptokinase, which is an enzyme secreted by several streptococcal bacteria. This drug is administered intravenously and can be used to dissolve blood clots in coronary vessels. However, streptokinase is nonspecific and can digest almost any protein, which can lead to many secondary problems. Another clot-dissolving enzyme that works faster and is more specific is called tissue plasminogen activator (tPA). This drug is made by transgenic bacteria and it converts plasminogen into the clot-dissolving enzyme plasmin.[3] There are also some anticoagulants that come ...
The Thrombosis VCEP plan to focus on curation of genes associated with Mendelian non-syndromic risk of venous thrombosis, such as protein S and C deficiencies, antithrombin deficiency (formerly antithrombin III deficiency), activated protein C resistance related to F5 and prothrombin. The VCEP will initially focus on SERPINC1 gene, associated with antithrombin deficiency, as this gene is one of the more sequenced genes for during a thrombophilia workup. We plan to move on to PROS1 and PROC to evaluate protein S and C deficiencies, respectively. As more pathogenic variants have been identified in the F5 and F2 genes related to thrombophilia risk, it will also be important to evaluate these genes for pathogenic variants in addition to the well described Factor V Leiden and Prothrombin variants.. The VCEP plans to meet monthly to begin specifying the ACMG/AMP Variant Curation Guidelines for SERPINC1. Once rule specifications are complete, we will then focus on PROS1 and PROC, which may only require ...

Base dose on pretreatment functional antithrombin activity and body weight. Initiate before delivery (peri-partum use) or about 24 hrs before surgery (surgical patients). If pregnant and undergoing surgery other than C-section, use peri-partum dose regimen. Give loading dose as 15 mins IV infusion, then maintenance dose by continuous IV infusion. Monitor antithrombin activity once or twice daily and adjust to maintain antithrombin activity between 80% and 120% of normal. May give another bolus dose if antithrombin activity is ,80% immediately post-procedure (use most recent antithrombin activity data to calculate dose). Thereafter, restart maintenance dose at the same rate of infusion as before the bolus. See literature.. ...
The anticlotting activities on some steps of the coagulation cascade of mollusc and mammalian heparins were studied. AT III-high affinity heparin is a more potent inhibitor than unfractionated heparin and mollusc heparin in the intrinsic and extrinsic pathways of thrombin and factor Xa generation. Mollusan heparin has about the same activity as the AT III high affinity-heparin on the inhibition of factor Xa and thrombin in the presence of antithrombin III and four times more inhibitory activity than unfractionated heparin on the heparin cofactor II mediated inhibition of thrombin ...
肝素經由它的硫化五糖序列與酵素抑制劑抗凝血酶(英语:antithrombin)III結合,使其構形改變而活化[35]。 活化的抗凝血酶III接著抑制凝血酶與凝血因子Xa(英语:factor Xa)以及其他蛋白酶,抑制的效果可因為肝素的加入而上升一千倍[36]。硫化五糖序列如下: GlcNAc/NS(6S)-GlcA-GlcNS(3S,6S)-IdoA(2S)-GlcNS(6S) 抗凝血酶III與肝素結合後導致的構形改變,造成它可抑制凝血因子Xa。至於凝血酶與抗凝血酶III之間的作用,除了酵素以外,還需要同時與肝素結合形成三元複合體(英语:ternary complex)才能達到抑制的效果;這部分肝素的高陰電性擔任了重要的角色[12]。因此,至少要具有十八個糖的肝素才能與凝血酶及抗凝血酶III產生有效的作用;但是與凝血因子Xa的作用只需要硫化五糖序列就可以了[37]。 ...

An ultra-thin hybrid film of amphiphilic iridium(III) complexes and synthetic saponite was manipulated by means of the modified Langmuir-Blodgett method. In the film deposited onto a quartz substrate, the external mixed molecular layer of amphiphilic iridium(III) complexes was reinforced by the inner layer of exfoliated synthetic saponite. As components of the molecular layer, two iridium(III) complexes were used: [Ir(dfppy)2(dc9bpy)]+ (dfppyH = 2-(4′,6′-difluorophenyl) pyridine; dc9bpy = 4,4′-dinonyl-2,2′-bipyridine) (denoted as DFPPY) and [Ir(piq)2(dc9bpy)]+ (piqH = 1-phenyisoquinoline)) denoted as PIQ). The emission spectra from the films changed from blue to red maxima with the decrease of a ratio of DFPPY/PIQ due to the energy transfer from excited DFPPY to PIQ. The intensity of red decreased with the increase of oxygen pressure through the quenching of excited iridium(III) complexes, promising a possibility as an oxygen-sensing film.
Binds to endothelial cell surfaces and plasma proteins and its activity depends on antithrombin. Heparin binds to antithrombin, causes a conformational change in the inhibitor, exposing its active site for more rapid interaction with proteases. Heparin acts as a co factor for the antithrombin-proteases reaction Antithrombin inhibits proteases espec thrombin 2a, 9a, 10a by forming stable complexes with them and the presence of heparin accelerates this reaction 1000x. The binding of AT Ill and unfractionated heparin t degradation of both factor Xa and thrombin. Pass: Binds to AT III. ...
Heparin was first studied in ACS in 1988 and has been a mainstay for acute ischemic heart disease therapy since then. Heparins represent a heterogeneous group of negatively charged, heavily sulfated glycosaminoglycans. Heparins have a heterogeneous effect on the coagulation cascade, although most of the effect is mediated through binding with antithrombin, causing a conformational change leading to inactivation of multiple enzymes in the coagulation cascade. While factors IXa, XIa, and XIIa are targets as well, thrombin (factor IIa) and factor Xa are the most clinically relevant. As mentioned, thrombin inhibition leads to inhibition of fibrin formation and factors needed for its cross-linking and stabilization. Heparins also have an impact on arterial and venous thrombosis by increasing vessel wall permeability and binding to von Willebrand factor, leading to some inhibition in platelet activation. Unfractionated heparin (UFH) represents a heterogeneous compound with some important limitations: ...
Abstract. We have investigated the basis of antithrombin deficiency in an asymptomatic individual (and family) with borderline levels (≈70% antigen and activit
Antithrombin, a plasma serpin, is relatively inactive as an inhibitor of the coagulation proteases until it binds to the heparan side chains that line the microvasculature. The binding specifically occurs to a core pentasaccharide present both in the heparans and in their therapeutic derivative heparin. The accompanying conformational change of antithrombin is revealed in a 2.9-A structure of a dimer of latent and active antithrombins, each in complex with the high-affinity pentasaccharide. Inhibitory activation results from a shift in the main sheet of the molecule from a partially six-stranded to a five-stranded form, with extrusion of the reactive center loop to give a more exposed orientation. There is a tilting and elongation of helix D with the formation of a 2-turn helix P between the C and D helices. Concomitant conformational changes at the heparin binding site explain both the initial tight binding of antithrombin to the heparans and the subsequent release of the antithrombin-protease ...

Since its discovery in 1917, heparin has been a fascinating, and in a way elusive, molecule. Heparin is a glycosoaminoglycan (GAG) formed by repeated sulphated oligosaccharide units. Natural preparations of heparin (usually obtained from bovine lung or porcine intestinal mucosa) can vary in the length of the polymeric unit and therefore have different molecular weights. As such, the biological actions of this GAG can vary quantitatively between different batches of the molecule. The initial activity ascribed to heparin was its capacity to prolong the process of blood clotting, an effect due to its potentiating interaction with the natural inhibitor of thrombin, antithrombin III. These properties have led to widespread use of heparin as an anticoagulant although scant attention has been paid to other biological activities of this GAG.. This situation has changed in recent years. In fact is has long been recognised that heparin has a wide range of biological effects in addition to its well ...

To the Editor:. The contribution by Troldborg, et al1 is a valuable addition to our understanding of disease, addressing half the question. Serine proteases do not function in isolation, but are also part of an enzyme-inhibitor interaction2. Noting higher enzyme concentrations in their cross-sectional study of patients with systemic lupus erythematosus1, direct correlation with nephritis and titers of anti-dsDNA, and inverse correlation with complement C3, the authors have demonstrated that serine protease levels appear to be markers of disease activity. It may also be worthwhile to assess whether their results reflect disease activity or alteration by the medications used in its treatment, as has been demonstrated for the major serine protease inhibitors, α-1-antitrypsin, α-2-macroglobulin, and antithrombin III2,3,4,5,6. Their implication of a pathophysiologic involvement is an interesting speculation, especially if a moderating component is considered.. Serine protease inhibitor levels are ...
