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
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 ...

antithrombin III Glasgow: abnormal antithrombin with increased heparin affinity & reduced ability to inactivate thrombin; associated with familial thrombosis; tryptic peptides Ala(371)-Arg(393) & Ser(394)-Arg(399) present in reduced amounts; Asp(187) replaced by Lys
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 ...

OBJECTIVE: To evaluate the efficacy and safety of fondaparinux compared with nadroparin for prevention of venous thromboembolism after arthroplasty. PATIENTS AND METHODS: One hundred fifteen patients were randomized into 2 treatment groups. Patients were given fondaparinux in Group I and nadroparin in Group II. Measurements were performed on Days 1, 5, and 21. The wound area was assessed with a subjective visual analog scale. RESULTS: The blood counts, clinical biochemical tests, and coagulation tests (ie, thrombin time, partial thromboplastin time, activated partial thromboplastin time, fibrinogen, prothrombin time-International Normalized Ratio, and antithrombin III activity) did not show statistically significant differences between Group I and Group II ...
Antithrombin-III exerts antiinflammatory effects via ligation of heparan sulfate proteoglycans. Here we show in vitro that recombinant human antithrombin-III attenuates CD11b/CD18 expression of activated neutrophils and monocytes in whole blood ex vivo. As leukocyte integrin expression is triggered by extracorporeal circulation, this observation may be of relevance for pharmacological treatment during cardiopulmonary bypass ...

... 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. ...
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. ...

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. NCI-GLOSS Definition: A drug that is used with another drug, warfarin, to treat blood clots that form deep in the veins and to prevent new blood clots from forming. It is a type of anticoagulant.

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. [provided by RefSeq, Jul 2009 ...

A long standing problem in anti-cancer drug development has been the limited value of preclinical mouse tumor models to reliably predict subsequent clinical activity. All too often highly encouraging preclinical results in mice are followed by complete failure in clinical trials, especially at the randomized phase III level. There are many possible reasons that have been postulated for this preclinical/clinical discrepancy. One which we have been studying for the past decade is the failure to use mouse models which duplicate the challenging circumstance of treating advanced (established) visceral metastatic disease after primary tumors have been surgically resected. Instead, preclinical treatment of established primary tumors or low volume (micro)metastatic disease, often confined to the lungs, have been the historical preclinical model norms. To address this problem we have developed several models of postsurgical advanced metastatic disease involving human tumor xenografts grown in SCID mice, ...

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 ...

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 ...
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.. ...

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 ...
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 ...

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.

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: ...
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 ...

The thrombosis in IBD is generally considered to result from the presence of a hypercoagulable state. Other contributing factors include bedrest, toxemia, and surgical procedures. Hemostatic abnormalities include thrombocytosis, elevated fibrinogen, factors V and VII, vitamin K, and decreased protein C and S, factor XIII, and antithrombin III levels (172,181,182). Sixty-three percent of CD and 25% of UC patients demonstrate free protein S deficiency. Protein C deficiency also occurs. Protein C activity may return to normal on disease remission or following subtotal colectomy (183). Other abnormalities include the presence of fibrin microclots. Platelets circulate in an activated state in IBD, and the increased platelet activation and aggregation found in this disorder may contribute to the risk of systemic thromboembolism and mucosal inflammation secondary to ischemia. Circulating immune complexes contribute to the development of vasculitis (184), which then predisposes to thrombosis. ...

At physiological temperature (310 K) at pH 7.4{,} about 70% of the partially bound and 30% of the incorporated Cm(iii) transferrin species are present in solution. The Cm(iii) results obtained by TRLFS are in very good agreement with Am(iii) EXAFS results{,} confirming the incorporation of Am(iii) at the Fe(iii) binding site at pH 8.5 ...
During attempted cannulation of the right internal jugular vein, you puncture the carotid artery in a patient who is to be heparinized intraoperatively.. 1. What is your management?. 2. Would you proceed with the case?. 3. How does heparin anticoagulate?. Heparin binds to antithrombin III and the activated forms of factors II, X, XI, XII, and XIII, having an anticoagulant effect of about ninety minutes. It may produce qualitative or quantitative platelet abnormalities.. 4. The patient is resistant to heparinization. What is the defect?. Antithrombin III deficiency. 5. What is the treatment? Fresh frozen plasma.. 5. What tests measure the intrinsic and common pathways? For the intrinsic pathway, phospholipid is added to the patients plasma, and the time taken for clot formation is taken. Decreased fibrinogen and dysfibrinogenemias prolong both intrinsic and extrinsic pathways. The partial thromboplastin time, or PTT, measures all factors of the intrinsic and common paths, except factor XIII. A ...
TY - JOUR. T1 - Issues in antithrombin therapy for UA/NSTEMI. AU - Alpert, Joseph S. AU - Budaj, A. J.. AU - Gurfinkel, E. P.. AU - Henry, T. D.. PY - 2001. Y1 - 2001. N2 - In September 2000, participants at the 4th Annual Experts Meeting of the International Cardiology Forum convened to discuss guidelines for the management of unstable angina/non-ST-elevation MI, recently published by North American and European task forces. Discussion of new recommendations for antithrombin therapy focused on the role of low-molecular-weight heparin (LMWH). Although most participants found the new guidelines largely consistent with existing data, and sufficiently adaptable to most clinical settings, there was concern that neither task force specified LMWH as the antithrombin of choice for the medical management of these patients. The new guidelines continue to endorse the use of unfractionated heparin, particularly for high-risk patients, despite the evidence for the efficacy of LMWH in this setting. This is ...
The present invention provides compositions and methods for the treatment of cardiovascular diseases. More particularly, the present invention relates to modifying thrombus formation by administering an agent which, inter alia, is capable of (1) inactivating fluid-phase thrombin and thrombin which is bound either to fibrin in a clot or to some other surface by catalyzing antithrombin; and (2) inhibiting thrombin generation by catalyzing factor Xa inactivation by antithrombin III (ATIII). The compositions and methods of the present invention are particularly usefull for preventing thrombosis in the circuit of cardiac bypass apparatus and in patients undergoing renal dialysis, and for treating patients suffering from or at risk of suffering from thrombus-related cardiovascular conditions, such as unstable angina, acute myocardial infarction (heart attack), cerebrovascular accidents (stroke), pulmonary embolism, deep vein thrombosis, arterial thrombosis, etc.
Plant annexins show distinct differences in comparison with their animal orthologues. In particular, the endonexin sequence, which is responsible for coordination of calcium ions in type II binding sites, is only partially conserved in plant annexins. The crystal structure of calcium-bound cotton annexin Gh1 was solved at 2.5Šresolution and shows three metal ions coordinated in the first and fourth repeat in types II and III binding sites. Although the protein has no detectable affinity for calcium in solution, in the presence of phospholipid vesicles, we determined a stoichiometry of four calcium ions per protein molecule using isothermal titration calorimetry. Further analysis of the crystal structure showed that binding of a fourth calcium ion is structurally possible in the DE loop of the first repeat. Data from this study are in agreement with the canonical membrane binding of annexins, which is facilitated by the convex surface associating with the phospholipid bilayer by a calcium ...

Abstract: 53 patients with lung tuberculosis were divided in 3 groups in accordance with severety of disease. Leukocyte elastase, cationic proteins in neutrophils, activities of a 1-proteinase and a 2-macroglobulin were determined in patients plasma. Thromboelastographic, coagulating, fibrinolytic indices, and antithrombin III activity were also determined in 28 patients of all 3 groups. Results demonstrated the high level of leukocyte elastase (6-fold more than normal) in plasma of patients with acute tuberculosis process. This group of patients demonstrated activation of intravascular coagulation proceeded on the background of significant decrease (up to 60%) of AT III activity. Conclusion: Acuity and severety of tuberculosis process in lung may be characterized by high activity of leukocyte elastase. Degranulating activity of neutrophils and releasing of elastase are the reason of AT III deficiency and increasing of intravascular coagulating activity in tuberculosis ...

In particular, mild methods of conjugating heparins to proteins, such as antithrombin III and heparin cofactor II, which provide covalent conjugates which retain maximal biological activity are described. Uses of these conjugates to prevent thrombogenesis, in particular in lung airways, such as found in infant and adult respiratory distress syndrome are also described.
TY - JOUR. T1 - Cerebral thrombosis associated with active Crohns disease.. AU - Calderón, R.. AU - Cruz-Correa, M. R.. AU - Torres, E. A.. PY - 1998. Y1 - 1998. N2 - An increased incidence of cerebral thromboembolic events has been reported in young patients with inflammatory bowel disease (IBD). It has been suggested that a hypercoagulable state is associated with clinical activity of the disease, with elevation of factors V, VIII, fibrinogen and platelets and a lowering of anti-thrombin III. We present the case of a 35 y/o male with refractory Crohns disease who complained of headaches, blurred vision and tonic-clonic seizures. The studies demonstrated an ischemic stroke of the left cerebral hemisphere, without vascular abnormalities. Elevation of factor VIII, platelets, and antithrombin III were found. The symptoms were relieved with medical treatment and the patient has continued in good health after resection of the diseased terminal ileum.. AB - An increased incidence of cerebral ...
Ardeparin, marketed under the US trade name Normiflo, is a low molecular weight heparin (LMWH) anticoagulant used for the prevention of postoperative venous thrombosis. Ardeparin is derived via peroxide degradation of heparin extracted from porcine intestinal mucosa. Its molecular weight ranges from 2000 to 15,000 with an average molecular weight of 5500 to 6500. Normiflo was withdrawn from the US market in March 2000.
Thrombin-antithrombin III complex (TAT) concentration was measured in 27 control and 155 intensive care patients to (a) establish normal reference ranges, (b) measure thrombin generation in critically ill patients, and (c) determine the characteristics of the TAT assay for the diagnosis of disseminated intravascular coagulation (DIC) in children. The normal reference range was 1-4.3 micrograms/l (median 2.3 micrograms/l), and 89.7% of patients had raised TAT concentrations. Median TAT concentrations in the presence of DIC (27 micrograms/l) were significantly higher than in its absence (8 micrograms/l). Sensitivity, specificity, and positive and negative predictive values of the assay were 97.3%, 28.3%, 76.3%, and 81.3%, respectively, at a cut off of 4 micrograms/l. Excess thrombin production occurs in the majority of critically ill children. The TAT assay is potentially useful in the diagnosis of DIC in children.. ...
How can this seemingly disparate evidence be integrated with what was known before? Older data, upon which the guidelines were based, had established that thrombophilia testing was predictive of the relative risk for initial VTE. The situation is completely different for patients who have already had a spontaneous VTE. Why? It has long been known that patients with spontaneous VTE are hypercoagulable, (untreated recurrence rates of 2% to 5% per year) no matter the result of thrombophilia testing. In part this is because comprehensive laboratory testing of clinically thrombophilic patients will yield negative results---no "laboratory lesion"--- in about 30%-40% of cases. The thinking is that those patients have a thrombophilic state that hasnt been discovered yet. To keep it in perspective, remember that the concept of hereditary thrombophilia has been around since the discovery, in 1963, of antithrombin deficiency (Egeberg O: Inherited antithrombin deficiency causing thrombophilia. Thrombosis ...

Targeted gene delivery using non-viral vectors is a highly touted scheme to reduce the potential for toxic or immunological side effects by reducing dose. In previous reports, TAT polyplexes with DNA have shown relatively poor gene delivery. The transfection efficiency has been enhanced by condensing TAT/DNA complexes to a small particle size using calcium. To explore the targetability of these condensed TAT complexes, LABL peptide targeting intercellular cell-adhesion molecule-1 (ICAM-1) was conjugated to TAT peptide using a polyethylene glycol (PEG) spacer. PEGylation reduced the transfection efficiency of TAT, but TAT complexes targeting ICAM-1 expressing cells regained much of the lost transfection efficiency. Targeted block peptides properly formulated with calcium offer promise for gene delivery to ICAM-1 expressing cells at sites of injury or inflammation. ...

Im a mild Tiger-Mom who happens to be from the Caribbean so my kids have to deal with high expectations. Sorry, its in my blood. Actually, Im not sorry at all. I expect them to aim for high grades, work hard at activities that they choose and never live with a sense of entitlement. I have a hard time lowering my expectations…except when it comes to myself. (More on that in another post). I grew up in this type of environment, so its all I know. My bio-daughter is used to it as well. She is the classic overachiever and seems to thrive when she is challenged. My stepdaughter is also brilliant, insanely athletic and very creative but being pushed doesnt motivate her. It actually stifles her. She needs more nurturing. I realized when she came to live with us, I had taken on the role of "Governess". For those of you who dont know what this means, think back to The Sound of Music and the oldest daughter, Liesl repeatedly saying "I dont need a governess!" A governess is an educated woman who ...

BACKGROUND AND OBJECTIVES: The G20210A polymorphism in the prothrombin gene is a common cause of inherited thrombophilia. Scarce information is available about the circumstances of the heralding thrombotic manifestation at different ages. The aim of this study was to determine the risk of spontaneous or secondary venous thromboembolism (VTE) among younger and older carriers of the G20210A prothrombin polymorphism. DESIGN AND METHODS: We performed a case-control study, investigating 650 patients with a first objectively documented deep venous thrombosis of the legs or pulmonary embolism and 703 individuals with no history of vascular disease. In all of them we carried out laboratory screening for antithrombin III, protein C and protein S deficiencies, and for the presence of the factor V Leiden and the G20210A prothrombin polymorphisms. RESULTS. After adjustment for other inherited causes of thrombophilia (deficiency of antithrombin III, protein C or S, factor V Leiden) the overall risk for VTE ...

Fibrin split product D-dimer (DD) is most probably involved in the development of vascular disorders. At 1.5 μM concentration DD inhibited the incorporation of D-[1-3H]glucosamine hydrochloride and [2-14C]acetate · Na into pericellular heparan sulphate (HS) of rabbit coronary endothelial cells without affecting other groups of glycosaminoglycans (GAGs). At the same time, DD reduced HS ability to bind antithrombin (AT) and suppressed NO production. The effect of DD on pericellular GAGs was similar to that of Nw-methyl-L-arginine, the competitive inhibitor of endothelial NO synthase (eNOS). L-Ascorbic acid, eNOS activator, increased the level of endogenous NO in the DD-treated cells, and restored HS accumulation and antithrombin binding. It is suggested that DD influence on endothelial HS may be mediated by NO production. Another effect of DD, namely, stimulation of plasminogen activator inhibitor-1 (PAI-1) secretion did not depend on the NO level. The decreased HS content, reduced anticoagulant ...
Hypertension is an important risk factor of atherothrombosis development. An additional cardiovascular risk of thromboembolic complications in hypertensive patients may be partly due to an imbalance between prothrombotic and fibrinolytic factors in the blood circulation. Its cause is mainly due to increased shear stress and renin-angiotensin-aldosterone (RAA) system pathological activation, especially angiotensin-converting enzyme (ACE) and angiotensin II (ANG II). A prothrombotic state in arterial hypertension and left ventricular hypertrophy increase the risk of ischemic stroke eightfold and heart infarction fourfold. The fibrinolytic system is one of the defense mechanisms for the prevention of intravascular thrombosis. Important components are protein anticoagulants (antithrombin III, protein C and S, heparin cofactor II) and short-acting, endothelial platelet inhibitors - nitric oxide (NO) and prostacyclin [3]. Hemostatic risk factors in arterial hypertension are: plasminogen activator ...

INTENDED USE: BIOPHEN H-CoII kit is a chromogenic assay for measuring Heparin Cofactor II activity in human plasma or in purified systems, using a chromogenic method, manual or automated, based on the inhibition of a constant but in excess amount of thrombin. TEST PRINCIPLE: Heparin Cofactor II is an anticoagulant protein which inhibits specifically thrombin. This inhibition is highly enhanced by glycoaminoglycans such as Dermatan Sulfate (1). By contrast with Heparin, Dermatan Sulfate activates specifically Heparin Cofactor II (7). The BIOPHEN H-CoII assay is a chromogenic method based on the inhibition of a constant and in excess amount of thrombin, by the tested Heparin Cofactor II in presence of dermatan sulfate, and measurement of residual thrombin by its amidolytic activity on a thrombin specific chromogenic substrate (SIIa-01). pNA is then released from the substrate. The amount of pNA released is directly related to the residual thrombin activity. There is an inverse relationship
OBJECTIVE: To investigate the effects of short term atorvastatin treatment on forearm vasodilatory response to reactive hyperaemia (RH%) and on components of the thrombosis-fibrinolysis system (antithrombin III, proteins and S, factors V and VII, von Willebrand factor, tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI-1)) in patients with heart failure. PATIENTS AND METHODS: 35 patients with heart failure were enrolled in this study; 17 patients received atorvastatin 10 mg/day and 18 patients received no statin for four weeks. Forearm blood flow (FBF) was measured by venous occlusion strain gauge plethysmography. RH% and forearm vasodilatory response to nitrate were defined as the percentage change of FBF from rest to the maximum flow during reactive hyperaemia and after nitrate administration, respectively. Plasma concentrations of antithrombin III, protein C, protein S, factor V, factor VII, von Willebrand factor, tPA, and PAI-1 were determined before and after treatment.

Although widely used for its anti-estrogen properties tamoxifen has estrogen like effects on a number of tissues including bone and liver. Previous studies suggest a preservation of lumbar spine density in postmenopausal women but the effect on the hip had not been addressed. To determine whether tamoxifen prevents bone loss in the early postmenopausal period bone mineral density at the lumbar spine and femoral neck was measured using dual energy X-ray absorptiometry at presentation and 6 monthly thereafter for 1 year in a prospective controlled study. Also indices of bone turnover, serum osteocalcin and urinary hydroxyproline excretion, were assessed. Fifteen early postmenopausal women with Stage I or II breast cancer treated with tamoxifen and 21 normal postmenopausal women were studied. Sex hormone binding globulin and antithrombin III levels in serum were also measured as indices of the hepatic estrogenic activity. Tamoxifen (20 mg daily) prevented bone loss at the femoral neck and lumbar spine.
Treatments include medications (anti inflammatory medicine, anticoagulants), increased ambulation, compression stockings and focusing on causative factors (antibiotics for infections). Other treatment modalities may include varicose vein stripping, insertion of a filter in the main vein in the abdomen (vena cava) and clot removal or bypass Medications used in treatment include Heparin, Reteplase (Retavase), Penicillin G, Clindamycin (Cleocin), Metronidazole (Flagyl), Amphotericin B (AmBisome). The edema associated with thrombophlebitis should subside upon treatment of the condition. If not, gentle decongestive therapy may be necessary. Medications used in treatment might include IV heparin, warfarin, oxymetholone, antithrombin III, Stanozolol, ethylestrenol. Medications will be based on underling or complication medical conditions, type and severity of thrombophlebitis, whether aseptic or septic. Taking an analgesic, such as aspirin or another nonsteroidal anti-inflammatory drug (NSAIDs) usually ...
