Deficiency of natural anticoagulant proteins C, S, and antithrombin in portal vein thrombosis: a secondary phenomenon? (1/21)

BACKGROUND: Hereditary deficiencies of natural anticoagulant proteins are implicated in the pathogenesis of portal vein thrombosis (PVT). Secondary deficiencies of these proteins have also been reported in PVT, making interpretation of concentrations difficult. AIMS: To characterise the coagulation profiles in adult patients with PVT and to investigate the possible mechanisms of natural anticoagulant protein deficiency. PATIENTS: Twenty nine adult patients with portal hypertension caused by PVT, and normal biochemical liver function tests. METHODS: Routine coagulation profiles and concentrations of proteins C, S, and antithrombin were measured; where indicated, corresponding concentrations in parents were also measured. Synchronous peripheral and hepatic or splenic vein concentrations were compared in seven patients undergoing interventional procedures, as were peripheral concentrations before and after shunt surgery in three patients. RESULTS: Deficiencies of one or more of the natural anticoagulant proteins occurred in 18 patients (62%), with six patients having combined deficiency of all three proteins. There were strong correlations between prothrombin and partial thromboplastin time ratios and concentrations of natural anticoagulant proteins. Family studies in nine cases of anticoagulant protein deficiency revealed possible hereditary deficiency in only three cases, and significantly lower concentrations of anticoagulant proteins in all PVT cases compared with parents. Levels of anticoagulant proteins tended to be lower in hepatic veins but higher in splenic veins compared with peripheral vein concentrations. Peripheral concentrations decreased after shunt surgery. CONCLUSIONS: Deficiency of natural anticoagulant proteins is common in PVT and is probably a secondary phenomenon in most cases, occurring as part of a global disturbance of coagulation variables. The mechanism for this remains unclear but may result from a combination of reduced hepatic blood flow and portosystemic shunting itself.  (+info)

Studies of the human factor VIII/von Willebrand factor protein. III. Qualitative defects in von Willebrand's disease. (2/21)

The Factor VIII/von Willebrand factor protein was characterized in two unrelated patients with von Willebrand's disease in whom procoagulant and Factor VIII/von Willebrand factor antigen levels were normal. In both patients evidence of an abnormal protein was observed on crossed antigen-antibody electrophoresis. In one patient the Factor VIII/von Willebrand factor protein eluted from Sepharose 4B in a position and distribution identical to normal with normal levels of procoagulant activity and antigen. However, the partially purified Factor VIII/von Willebrand factor protein had markedly reduced von Willebrand factor activity in a ristocetin assay. In the second patient the peak of Factor VIII/von Willebrand factor protein, antigen, and procoagulant activity eluted from a Sepharose 4B column with an estimated molecular weight of approximately half that of normal. This protein had no von Willebrand factor activity. In both patients the reduced Factor VIII/von Willebrand factor protein subunit was indistinguishable from normal on polyacrylamide gel electrophoresis. These studies indicate that in some patients with von Willebrand's disease there is a qualitative defect of the Factor VII/von Willebrand factor protein; the total amount of protein, antigen, and procoagulant activity are normal while the von Willebrand factor activity is deficient.  (+info)

Coagulation and bleeding disorders: review and update. (3/21)

Hemostasis is initiated by injury to the vascular wall, leading to the deposition of platelets adhering to components of the subendothelium. Platelet adhesion requires the presence of von Willebrand factor and platelet receptors (IIb/IIIa and Ib/IX). Additional platelets are recruited to the site of injury by release of platelet granular contents, including ADP. The "platelet plug" is stabilized by interaction with fibrinogen. In this review, I consider laboratory tests used to evaluate coagulation, including prothrombin time, activated partial thromboplastin time, thrombin time, and platelet count. I discuss hereditary disorders of platelets and/or coagulation proteins that lead to clinical bleeding as well as acquired disorders, including disseminated intravascular coagulation and acquired circulating anticoagulants.  (+info)

Activated partial thromboplastin time as a screening test of minor or moderate coagulation factor deficiencies for canine plasma: sensitivity of different commercial reagents. (4/21)

To determine the sensitivity for detection of coagulation factor deficiencies by commercial reagents for canine plasma, 5 commercial activated partial thromboplastin time (APTT) reagents with different types of contact activator and phospholipid of various origin were examined. Thirty canine plasma samples with minor or moderate deficiencies of coagualition factors that influence the APTT were examined. Significant differences were found for the sensitivity of various reagents, but no correlation was found with the type of contact activator. Following the test instructions provided by the manufacturers, the number of APTT results that were prolonged beyond the reference range varied between 20 and 30 (sensitivity = 0.67-1.00); the number of corresponding results using a standardized test protocol varied between 19 and 28 (sensitivity: 0.63-0.93). The most sensitive reagent contained kaolin as a contact activator and a human placental thromboplastin. The results of this study indicate that the APTT test optimized for human plasma is also a sensitive screening test of the intrinsic system of canine plasma, provided that a suitable reagent is used.  (+info)

Fibrinogen Ales: a homozygous case of dysfibrinogenemia (gamma-Asp(330)-->Val) characterized by a defective fibrin polymerization site "a". (5/21)

Congenital homozygous dysfibrinogenemia was diagnosed in a man with a history of 2 thrombotic strokes before age 30. His hemostatic profile was characterized by a dramatically prolonged plasma thrombin clotting time, and no clotting was observed with reptilase. Complete clotting of the abnormal fibrinogen occurred after a prolonged incubation of plasma with thrombin. The release of fibrinopeptides A and B by thrombin and of fibrinopeptide A by reptilase were both normal. Thrombin-induced fibrin polymerization was impaired, and no polymerization occurred with reptilase. The polymerization defect was characterized by a defective site "a," resulting in an absence of interaction between sites A and a, indicated by the lack of fragment D(1) (or fibrinogen) binding to normal fibrin monomers depleted in fibrinopeptide A only (Des-AA fm). By SDS-PAGE, the defect was detected on the gamma-chain and in its fragment D(1). The molecular defect determined by analysis of genomic DNA showed a single base change (A-->T) in exon VIII of the gamma-chain. The resulting change in the amino acid structure is gamma 330 aspartic acid (GAT) --> valine (GTT). It is concluded that the residue gamma-Asp(330) is essential for the normal functioning of the polymerization site a on the fibrinogen gamma-chain.  (+info)

Decreased coagulability has no clinically relevant effect on atherogenesis: observations in individuals with a hereditary bleeding tendency. (6/21)

BACKGROUND: Hemostasis affects ischemic cardiovascular disease through its role in formation of occluding arterial thrombi. Several studies suggest that hemostasis also might play a role in atherogenesis. We investigated whether individuals with an inherited bleeding tendency are protected against development of atherosclerosis. METHODS AND RESULTS: A total of 76 individuals with an inherited bleeding tendency (hemophilia and von Willebrand disease) and 142 healthy controls were included in the present study. Early atherosclerotic vessel-wall changes were quantified by measurement of intima-media thickness in the carotid and femoral arteries by B-mode ultrasonography. To validate intima-media thickness measurements, measurements also were performed in 77 individuals with clinically proven atherosclerosis and in 34 healthy, age-matched controls. A large difference in intima-media thickness was found between individuals with proven atherosclerosis and healthy controls, in particular for the femoral artery (difference for carotid artery, 0.16 mm; femoral artery, 0.53 mm). Comparison between patients with a bleeding tendency and healthy controls showed only minimally reduced intima-media in femoral artery in individuals with a bleeding tendency (adjusted difference, -0.078 mm; 95% CI, -0.17 to 0.018 mm). Subgroup analysis revealed that in subjects with moderate to severe hemophilia, vessel walls were thinnest (adjusted difference, -0.10 mm; 95% CI, -0.27 to 0.061 mm). CONCLUSIONS: Hypocoagulability caused by hemophilia or von Willebrand disease has at most a limited effect on atherogenesis.  (+info)

Neonatal coagulation problems. (7/21)

Compound heterozygosity of novel missense mutations in the gamma-glutamyl-carboxylase gene causes hereditary combined vitamin K-dependent coagulation factor deficiency. (8/21)

Hereditary combined vitamin K-dependent (VKD) coagulation factor deficiency is an autosomal recessive bleeding disorder associated with defects in either the gamma-carboxylase, which carboxylates VKD proteins to render them active, or the vitamin K epoxide reductase (VKORC1), which supplies the reduced vitamin K cofactor required for carboxylation. Such deficiencies are rare, and we report the fourth case resulting from mutations in the carboxylase gene, identified in a Tunisian girl who exhibited impaired function in hemostatic VKD factors that was not restored by vitamin K administration. Sequence analysis of the proposita did not identify any mutations in the VKORC1 gene but, remarkably, revealed 3 heterozygous mutations in the carboxylase gene that caused the substitutions Asp31Asn, Trp157Arg, and Thr591Lys. None of these mutations have previously been reported. Family analysis showed that Asp31Asn and Thr591Lys were coallelic and maternally transmitted while Trp157Arg was transmitted by the father, and a genomic screen of 100 healthy individuals ruled out frequent polymorphisms. Mutational analysis indicated wild-type activity for the Asp31Asn carboxylase. In contrast, the respective Trp157Arg and Thr591Lys activities were 8% and 0% that of wild-type carboxylase, and their compound heterozygosity can therefore account for functional VKD factor deficiency. The implications for carboxylase mechanism are discussed.  (+info)

Factor IX Complex is a sterile, lyophilized concentrate composed of a number of Vitamin K-dependent clotting factors found in functioning human plasma. Also known as prothrombin complex concentrate, products containing this complex often include Factor IX (antihemophilic factor B), Factor II (prothrombin), Factor X (Stuart-Prower Factor), and low levels of Factor VII (proconvertin) derived from human plasma. Many commercially available products also contain low levels of other antithrombotic proteins. For example, Kcentra (FDA) also contains the antithrombotic proteins C and S, while Bebulin VH (FDA) contains heparin. Coagulation factors are purified from pooled human plasma and subsequently sterilized and treated. Although Factor IX Complex products contain many different coagulation components, Factor IX is the lead component for potency and efficacy, particularly when used for the treatment of bleeding associated with Hemophilia B (Factor IX deficiency). As the product Kcentra, Factor IX ...
It has been appreciated for a very long time that infections, particularly bacterial infections of the blood leading to severe sepsis, trigger a hypercoaguable state that sometimes leads to overt disseminated intravascular coagulation. We now recognize that endotoxins and other bacterial, fungal, and viral products can activate the toll receptors, leading to the elaboration of inflammatory cytokines (1) that in turn elicit tissue factor expression to trigger the blood clotting process (2). More recently, we have begun to appreciate the critical role played by natural anticoagulants in controlling the processes leading to septic shock (3). Of these natural anticoagulants, the protein C anticoagulant pathway seems to play a particularly important role in dampening the inflammatory response that occurs with endotoxin and bacteremia. It has now become clear that many of the components in the pathway possess multiple activities that contribute to the regulation of a variety of anticoagulant and ...
Once the identity of an inhibitor has been established, its titer is determined using the Bethesda assay. The inhibitor titer is defined as the dilution of patient plasma that produces 50 percent inhibition of the factor VIII activity and is expressed as Bethesda units per mL (BU/mL). Inhibitors are classified as low titer or high titer when the titers are less than 5 BU/mL or greater than 5 BU/mL, respectively. ...
Objectives: Therefore, our study objectives are: 1) Assessment of the frequency of myocardial dysfunction (segmental wall motion abnormalities, cardiac-specific enzyme elevations, and ECG changes) in patients with SAH. 2) Determination of predictive clinical variables for the occurrence of myocardial dysfunction following SAH. 3) Impact of myocardial dysfunction on neurological prognosis: death, secondary cerebral ischemia, hydrocephalus and rebleeding.. Methods: For this purpose serial echocardiograms and ECGs will be obtained and cardiac enzymes will be measured in 200-400 patients admitted to hospital with SAH in the four participating centers. The clinical variables that will be studied to predict cardiac dysfunction are: medical history, the CT-scan score, circulatory parameters, blood samples, medication, surgical intervention (coiling or clipping), and the neurological condition (Glasgow Coma Scale). The echocardiograms, ECGs and cardiac enzymes will be studied to determine if they have ...
Hereditary combined vitamin K-dependent clotting factors deficiency (VKCFD) is a rare congenital bleeding disorder resulting from variably decreased levels of coagulation factors II, VII, IX and X as well as natural anticoagulants protein C, protein S and protein Z. The spectrum of bleeding symptoms ranges from mild to severe with onset in the neonatal period in severe cases. The bleeding symptoms are often life-threatening, occur both spontaneously and in a surgical setting, and usually involve the skin and mucosae. A range of non-haemostatic symptoms are often present, including developmental and skeletal anomalies. VKCFD is an autosomal recessive disorder caused by mutations in the genes of either gamma-glutamyl carboxylase or vitamin K2,3-epoxide reductase complex. These two proteins are necessary for gamma-carboxylation, a post-synthetic modification that allows coagulation proteins to display their proper function. The developmental and skeletal anomalies seen in VKCFD are the result of defective
According to the recently described immunothrombosis concept [8], adequate and controlled coagulation activation would stand for an essential innate immune defense mechanism. When over-activated, coagulation pathways however switch from a beneficial to an uncontrolled noxious response. Similarly, excessive neutrophil activation could have deleterious consequences, notably by sustaining coagulation through NETs formation. In the present study, we report that rhTM both impact coagulation and neutrophil activation, two main actors of immunothrombosis.. Sepsis is indeed always associated with the activation of the coagulation cascade [28], resulting in excessive thrombin formation, defective fibrinolysis and consumption of natural anticoagulant proteins, ultimately leading to DIC. Nevertheless, impairment of fibrinolysis plays a key role in microvascular thrombosis, responsible for multiple organ failure syndrome and death [29]. Delayed fibrinolysis might therefore also contribute to septic ...
Liver disease is associated with impairment of the haemostatic function due to the abnormal and decreased synthesis of the clotting factors. It is thus only logical to have considered assessment of the clotting profile (to include prothrombin time (PT) and activated partial thromboplastin time (aPTT)) to be an integral part of the comprehensive assessment of a patient who presents with liver impairment. Laboratory abnormalities of coagulation are considered to be a predictive risk factor for bleeding, but patients with liver disease do not have bleeding pattern as those who have coagulation factor deficiencies. Recent experiments have cast doubts over the use of PT and aPTT as a marker of bleeding in liver disease and the use of such tests to decide the need for plasma replacement before interventions like liver biopsy. This article reviews the relevance of the clotting profile in liver disease, the other factors involved in the haemostatic failure associated with it, and the technical problems ...

Crush injuries occur when tissue is caught between two objects causing increased pressure. When this pressure is exerted over a long period of time, tissue is damaged resulting in lacerations, fractures and anaerobic injuries. When blood flow is cut off, oxygen does not make it to the tissue which results in a reversion to anaerobic metabolism generating lactic and pyruvic acids. In time, this damages more tissue causing the release of more acids and by-products of incomplete metabolism. Eventual results are more swelling and coagulation problems, loss of tissue and loss of life. ...
Multiple lines of evidence in animal models and in humans support the conclusion that the reduced capacity for fatty acid utilization in the hypertrophied and failing heart involves gene regulatory mechanisms related to the deactivation of PPARα signaling (Figure 3 and refs. 32, 90, 91). The deactivation of PPARα signaling in the hypertrophied and failing heart occurs during the early stages and at both transcriptional and posttranscriptional levels (90, 92). Well-known effectors of cardiac hypertrophy and remodeling, such as angiotensin II and hypoxia, reduce activity of PPARα, leading to a reduction in the rate of mitochondrial FAO (93-95). In addition, decreased generation of activating ligands through reduced triglyceride droplet dynamics may also contribute to decreased PPARα signaling in the failing heart (96). The role of altered PPAR signaling and fuel shifts as causative in the pathogenesis of cardiac functional and structural remodeling (versus as a secondary phenomenon) is an area ...
Cerebral vasospasm (CVS) is a common and severe complication of aneurysmal subarachnoid hemorrhage (aSAH). Despite the improvement in treatment of aSAH, CVS complicating aSAH has remained the main cause of death. CVS begins most often on the third day after the ictal event and reaches the maximum on the 5th-7th postictal days. Several therapeutic modalities have been employed to prevent or reverse CVS. The aim of this review is to summate all the available drug treatment modalities for vasospasm.

As both APTT and APTT-based coagulation method cannot distinguish heparin effect from intrinsic coagulation factor deficiency, we implemented thromboelastography (TEG) for the coagulation assessment in a patient with hemophilia A undergoing an endovascular surgery with heparinization. A 68-year-old male with hemophilia A underwent endovascular aortic repair for abdominal aortic aneurism. TEG results showed recovery of coagulation time (R) in both kaolin assay (CK) and kaolin-heparinase assay (CKH) after factor VIII replacement before heparinization. Against our expectations, R-CKH was slightly prolonged (9.0 min) during heparinization. After the administration of protamine sulfate, R in both assays showed similar values within the normal ranges. The combination of CK and CKH assays could be useful to estimate factor VIII (FVIII) level when heparin concentration is low or without heparin; however, caution should be necessary for estimation of FVIII level by TEG under the effect of medium- or high-dose

Coagulopathy occurs in 1 in for severely injured trauma patients, but there is no suitable point-of-care device that can test for bleeding risk in a trauma patient. For this reason, we have developed and tested a bench-top prototype in which blood samples can be tested for coagulopathy using a microfluidic card. The prototype develop with this LSDF grant uses a portable computer and custom software to control each subsystem. A syringe pump is operated by the software to flow a small sample of blood into the microfluidic card. A commercial heater controller is used to maintain the microfluidic card and blood sample at 37°C. A custom-built, miniature fluorescent microscope acquires video images of coagulation in the microfluidic card for real-time analysis. The prototype is a complete, stand-alone system that has a small footprint. It will be used for in vitro testing and clinical studies for coagulopathy ...
We studied the risk of recurrent thrombosis and death in a large cohort of 224 patients with a first venous thrombosis of the upper extremity. The cumulative incidence of recurrence after 2 years was 8% (95% CI, 4% to 12%), and the incidence rate of recurrence was 43.2 per 1000 person-years (95% CI, 27.8 to 58.7). Women had a 2-fold higher recurrence risk than men and appeared to have, contrary to men, a decreased survival in the absence of malignancy. There appeared to be an increased risk of recurrence for patients with a first nonsubclavian vein thrombosis and for patients with a BMI ≥25 kg/m2. Patients with a first thrombosis resulting from a CVC had a decreased risk of a recurrent event.. After discontinuation of treatment (n=163), the 2-year cumulative incidence was similar at 7% (95% CI, 2% to 12%), which was also similar to the incidences found in 2 previous smaller studies (4.2% and 7%) that included only patients after discontinuation of treatment.5,17 The incidence of recurrence in ...

The site of bleeding may provide an indication of the hemostatic abnormality. Mucocutaneous bleeding, including petechiae, ecchymoses, epistaxis, or gastrointestinal, genitourinary, or heavy menstrual bleeding, is characteristic of qualitative or quantitative platelet disorders. Purpura is often associated with thrombocytopenia and commonly indicates a systemic illness. Bleeding into joints and potential spaces, such as between fascial planes and into the retroperitoneum, as well as delayed bleeding, is most commonly associated with coagulation factor deficiencies. Patients who demonstrate both mucocutaneous bleeding and bleeding in deep spaces may have disorders such as disseminated intravascular coagulation (DIC), in which both platelet abnormalities and coagulation factor abnormalities are present. Basic hemostatic tests and clinical evaluation are generally adequate for diagnosis (Table 41-1). Additional hemostatic studies are ordered as indicated (Table 41-2). ...

Much evidence exists for GRAS proteins functioning in transcriptional regulation: they are generally located in the nucleus (Bolle, 2004), they show association with promoters in vivo (Cui et al., 2007), and a GRAS protein has been shown to have an innate capability to activate RNA polymerase in both S. cerevisiae and in plants (Morohashi et al., 2003). However, transcription factor classification generally requires direct DNA association, and the emerging evidence suggests that GRAS proteins may function to regulate the action of other transcription factors (de Lucas et al., 2008; Feng et al., 2008). Here, we show that the GRAS protein NSP1 binds directly to DNA and does so in a complex with a second GRAS protein, NSP2. NSP1 can activate RNA polymerase in S. cerevisiae, and this transcriptional activity of GRAS proteins has been previously validated in plant cells using L. longiflorum SCL, a GRAS protein from lily (Morohashi et al., 2003). The association of NSP1 with the ENOD11 promoter ...
Its possible to become pregnant during the menstrual cycle immediately after a miscarriage. But if you and your partner decide to attempt another pregnancy, make sure youre physically and emotionally ready. Ask your health care provider for guidance about when you might try to conceive.. Keep in mind that miscarriage is usually a one-time occurrence. Most women who miscarry go on to have a healthy pregnancy after miscarriage. Less than 5 percent of women have two consecutive miscarriages, and only 1 percent have three or more consecutive miscarriages.. If you experience multiple miscarriages, generally two or three in a row, consider testing to identify any underlying causes - such as uterine abnormalities, coagulation problems or chromosomal abnormalities. If the cause of your miscarriages cant be identified, dont lose hope. About 60 to 80 percent of women with unexplained repeated miscarriages go on to have healthy pregnancies.. PreviousNext ...

N2 - A 67-year-old patient was admitted to the hospital to perform an esophagogastrectomy because a lesion at the lower esophagus was strongly suspicious for cancer. Her medical history and her family history were negative for bleeding tendency or thrombosis. Her activated partial thromboplastin time (aPTT) was prolonged (44 s) whereas her prothrombin time (PT) was normal (11 s) presurgery. Mixing of her plasma with normal plasma corrected her prolonged aPTT (27.9 s). Prolonged incubation shortened the patients aPTT (36.3 s). Fletcher factor activity was found to be 50%. The patient underwent an esophagogastrectomy without bleeding complications under spinal anesthesia. Fletcher factor deficiency, a rare ...
A prospective study of 46 infant deaths occurring between 3 and 100 weeks of age was performed and comprised a structured necropsy followed by collection of lung washings for surfactant phospholipid analysis and samples for microbiological examination. Of the 46 infants studied, 23 died from sudden infant death syndrome (SIDS) alone; SIDS was the cause of death in a further 12 but there were additional clinical or pathological findings insufficient in themselves to account for the death (SIDS-plus). In 11 there were other causes of death (non-SIDS). The lung washings from infants dying from SIDS had significantly lower concentrations of phosphatidylcholine and a significantly lower palmitate content in the phosphatidylcholine. There was no association between surfactant phospholipid abnormality and the presence of recognised pathogens, histological evidence of pulmonary inflammation, aspiration of stomach contents, age at death, sex, and death-postmortem interval. There were, however, lower ...

Therefore, communication is social interaction where at least two interacting agents share a common set of signs and a common set of semiotic rules. This commonly held rule in some sense ignores autocommunication, including intrapersonal communication via diaries or self-talk, both secondary phenomena that followed the primary acquisition of communicative competences within social interactions.. In light of these weaknesses, Barnlund (2008) proposed a transactional model of communication.[49] The basic premise of the transactional model of communication is that individuals are simultaneously engaging in the sending and receiving of messages.. In a slightly more complex form a sender and a receiver are linked reciprocally. This second attitude of communication, referred to as the constitutive model or constructionist view, focuses on how an individual communicates as the determining factor of the way the message will be interpreted.

Bleeding symptoms are common in healthy children but occasionally may indicate an underlying congenital or acquired bleeding diathesis. The rare bleeding disorders (RBDs) comprise inherited deficiencies of coagulation factors I (congenital fibrinogen deficiencies), II, V, VII, X, XI, and XIII and combined factor deficiencies, most notably of factors V and VIII and of vitamin K-dependent factors. These disorders often manifest during childhood and may present with recurrent or even serious or life-threatening bleeding episodes, particularly during the neonatal period. Accordingly, primary care and other nonhematologist pediatric providers should be familiar with the clinical presentation and initial evaluation of these rare disorders. Bleeding manifestations generally vary within the same RBD and may be indistinguishable from 1 RBD to another or from other more common bleeding disorders. Serious bleeding events such as intracranial hemorrhage may be heralded by less serious bleeding symptoms. The ...

Whereas red blood cell transfusions have been used since the 19th century, plasma has only been available since 1941. It was originally mainly used as volume replacement, mostly during World War II and the Korean War. Over the years, its indication has shifted to correct coagulation factors deficiencies or to prevent bleeding. Currently, it remains a frequent treatment in the intensive care unit, both for critically ill adults and children. However, observational studies have shown that plasma transfusion fail to correct mildly abnormal coagulation tests. Furthermore, recent epidemiological studies have shown that plasma transfusions are associated with an increased morbidity and mortality in critically ill patients. Therefore, plasma, as any other treatment, has to be used when the benefits outweigh the risks. Based on observational data, most experts suggest limiting its use either to massively bleeding patients or bleeding patients who have documented abnormal coagulation tests, and refraining for
Coumadin is a Brand name for an anticoagulant (or blood thinner) drug that contains warfarin as an active ingredient. Warfarin prevents the formation of blood clots as well as their migration by inhibiting vitamin K-dependent coagulation factors. Coumadin is indicated for: treatment and prophylaxis of venous thrombosis and pulmonary embolism as its extension, treatment and prophylaxis of thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement, reduction of recurrent myocardial infarction and thromboembolic events (such as stroke or systemic embolization) after myocardial infarction and therefore the reduction the risk of death.. Coumadin has no effects on an established thrombus, and cant reverse ischemic tissue damage. The main targets of anticoagulant therapy are to prevent further extension of the formed blood clot and to prevent the risk of secondary thromboembolic complications that may result in serious and possibly fatal outcomes. Despite its ...

In this study, we found that the risk of a first venous thrombosis is 2-fold higher in men than in women once female reproductive risk factors for venous thrombosis are taken into account. These results were found in all age categories and were not affected by adjustment for body mass index and smoking or by the exclusion of participants with malignancy.. To the best of our knowledge, this is the first study to assess the risk of first venous thrombosis in men compared with women with and without reproductive risk factors separately. We found a relative risk of 2 when comparing men with women without reproductive risk factors, which indicates that the intrinsic risk of venous thrombosis is higher in men than in women. Until now, this higher intrinsic risk of venous thrombosis in men has mostly been noted in recurrence research.10-14 Studies have shown that men have a 2-fold higher risk of recurrent venous thrombosis than women.10-14 It was hypothesized that this could be explained by a reduction ...

The CLSI guidelines have established that, ideally, the sensitivity of APTT reagent instrument combination has to be at least 30 IU/dL for factors VIII, IX and XI [4]. Moreover, PT and APTT within the reference values have been considered safe and used to guide transfusions in surgical interventions, assuming that factor activities were >30 IU/dL [8]. However, FVIII or FIX levels ,60 IU/dL in hemophiliac carriers have been found to increase (about two fold) the risk of bleeding manifestations, particularly after medical interventions [9]. Even FXI deficiency has variable bleeding tendency, and patients with levels of 40 IU/ dL could present severe bleeding and low thrombin generation [10]. All these suggest that it is important to recognize mild deficiencies of these factors by the most used screening test, the APTT. Furthermore, it has been reported that a particular APTT reagent instrument combination did not detect a single factor XI deficiency in a patient who bled more than expected during ...

We developed a method, ChIP-sequencing (ChIP-seq), combining chromatin immunoprecipitation (ChIP) and massively parallel sequencing to identify mammalian DNA sequences bound by transcription factors in vivo. We used ChIP-seq to map STAT1 targets in interferon-γ (IFN-γ)-stimulated and unstimulated human HeLa S3 cells, and compared the methods performance to ChIP-PCR and to ChIP-chip for four chromosomes. By ChIP-seq, using 15.1 and 12.9 million uniquely mapped sequence reads, and an estimated false discovery rate of less than 0.001, we identified 41,582 and 11,004 putative STAT1-binding regions in stimulated and unstimulated cells, respectively. Of the 34 loci known to contain STAT1 interferon-responsive binding sites, ChIP-seq found 24 (71%). ChIP-seq targets were enriched in sequences similar to known STAT1 binding motifs. Comparisons with two ChIP-PCR data sets suggested that ChIP-seq sensitivity was between 70% and 92% and specificity was at least 95%.

Histology laboratories have historically used all sorts of techniques to adhere tissues to slides. In the past, when charged slides were considered too costly for routine sectioning, laboratories relied on albumin or other proteins to help tissues adhere to slides. Commercial reagents were (and still are) available to be used as additives to the water bath. The challenge, though, is consistency. Each technologist will fill their water bath differently and add different amounts of adhesive to the bath. While one person may be generous with the adhesive, another may be stingy, making background staining difficult to control. Adhesives do have their own limitations (eg, background staining on H&E) and may even interfere with immunohistochemistry stains. Charged slides are now readily available and work well with laboratory stains, decreasing the probability of background or other anomalies associated with adhesives. Because all slides are treated consistently, there is limited variability between ...
