Explain the important role of plasma D-dimer in cancers. Plasma D-dimer is increased in various tumors. However, the predictive value of plasma D-dimer is unclear. This study is aimed to evaluate the prognostic value of the D-dimer level in patients managed with intensity-modulated radiation for endometrial cancer. The D-dimer levels of forty patients with endometrial cancer were assessed before (D1) and after (D2) intensity-modulated radiation therapy (IMRT), respectively. The D-dimer level changes (ΔD) were defined as D2 minus D1...

OBJECTIVE: According to the international guidelines, fresh frozen plasma (FFP) is unanimously used to treat coagulation disorders. The quality of FFP is critical for the clinical transfusion. Till now, few studies have integratedly evaluated the differences of FFP from blood donors at between high altitude (HA) and low altitude (LA). Besides, there were no special quality standards for HA FFP in China. MATERIALS AND METHODS: Up to 41 HA (Lhasa, 3700 m) and 46 LA (Chengdu, 500 m) blood donors were included in our study to estimate the differences of FFP from HA and LA blood donors...

Previous studies have indicated that the G protein-coupled secretin receptor is present as a homo-dimer, organized through symmetrical contacts in transmembrane domain IV, and that receptor dimerization is critical for high potency signalling by secretin. However, whether all of the receptor exists in the dimeric form or if this is regulated, is unclear. We used measures of quantal brightness of the secretin receptor tagged with monomeric enhanced green fluorescent protein (mEGFP) and Spatial Intensity Distribution Analysis to assess this...

BACKGROUND: Laboratory findings have suggested that systemic and vascular inflammation can impair the antiatherogenic function of high-density lipoproteins (HDLs). However, evidence from population studies is sparse. OBJECTIVE: The objective of the study was to assess if blood inflammatory markers modify the risk of recurrent coronary events associated with apolipoprotein A-I (apoA-I) and HDL cholesterol (HDL-C) among postinfarction patients. METHODS: ApoA-I, HDL-C, and inflammatory markers (C-reactive protein [CRP], serum amyloid A (SAA), fibrinogen, von Willebrand factor [vWF], and D-dimer) were measured from blood samples of 1028 patients drawn 2 months after an index myocardial infarction (MI)...

BACKGROUND: Hypercoagulability induced by the imbalance between von Willebrand factor (VWF) secretion and its cleaving protease (ADAMTS-13) has been correlated with cancer metastasis. The aim of this study was to explore the prognostic significance of the VWF/ADAMTS-13 ratio in advanced non-small-cell lung cancer (NSCLC). METHODS: Pre-treatment sera/plasma levels of VWF, ADAMTS-13, VWF/ADAMTS-13 ratio, factor (F) VIII, and other clinical/laboratory parameters were measured in 119 patients with advanced NSCLC and 102 healthy controls...

AIM: Cancer increases the risk of venous thromboembolism (VTE) and circulating tumor cells (CTCs) are associated with an increased risk of VTE and, thus, with increased D-dimers as a product of fibrinolysis. Tissue plasminogen activator (tPA) is one of the key enzymes in the fibrinolytic pathway. Its activity is crucial in maintaining the balance between blood coagulation and fibrinolysis. This study aimed to analyze the association between CTCs and tPA in patients with primary breast cancer before surgery...

OBJECTIVE: To estimate D-Dimer interval likelihood ratios (iLRs) for diagnosing pulmonary embolism (PE). METHODS: The authors used pooled patient-level data from five PE diagnostic management studies to estimate iLRs for the eight D-Dimer intervals with boundaries 250, 500, 750, 1000, 1500, 2500, and 5000 ng/mL. Logistic regression was used to fit the data so that an interval increase corresponds to increasing the likelihood ratio by a constant factor. RESULTS: The iLR for the D-Dimer interval 1000-1499 ng/mL was essentially 1...

  Disseminated intravascular coagulopathy (DIC) is an acquired disorder of hemostasis resulting in activation of the coagulation and fibrinolytic pathways. It is reported secondarily to multiple disease processes and can be associated with increased mortality. Previous research at Tampa's Lowry Park Zoo (LPZ) demonstrated that Florida manatees ( Trichechus manatus latirostris) with cold stress syndrome (CSS) demonstrated thromboembolic disease. The object of this retrospective study was to establish the presence and clinical relevance of DIC in Florida manatees admitted to LPZ for rehabilitation from 07 March 2010 to 15 August 2015...

BACKGROUND: Blood coagulation plays a crucial role in the blastocyst implantation process and its alteration may be related to in vitro fertilization (IVF) failure. We conducted a prospective observational longitudinal study in women eligible for IVF to explore the association between alterations of coagulation with the IVF outcome and to identify the biomarkers of hypercoagulability which are related with this outcome. METHODS: Thirty-eight women eligible for IVF (IVF-group) and 30 healthy, age-matched women (control group) were included...

Seed shattering is an agronomically important trait. Two major domestication factors are responsible for this: qSH1 and SH5. Whereas qSH1 functions in cell differentiation in the abscission zone (AZ), a major role of SH5 is repression of lignin deposition. We have determined that a KNOX protein, OSH15, also controls seed shattering. Knockdown mutations of OSH15 showed reduced seed shattering phenotypes. Co-immunoprecipitation experiments revealed that OSH15 interacts with SH5 and qSH1, two proteins in the BELL homeobox family...

BACKGROUND: Regular blood transfusion and compliance with iron chelation therapy has markedly improved life expectancy in thalassemia; however, this improvement is accompanied by several complications of this chronic disease including thromboembolic disorders. The objective of this work is to study natural coagulation inhibition as well as the fibrinolysis processes in thalassemic children who are otherwise in a steady state with no overt clinical manifestations of thromboembolism. METHODS: In a case-control study design conducted at Sohag University Hospital, Sohag, Egypt, 50 thalassemic children and 20 age- and sex-matched healthy controls were compared as regards prothrombin concentration, international normalized ratio, partial thromboplastin time, protein C, protein S, antithrombin III, D-dimers, and thrombin activatable fibrinolysis inhibitor (TAFI)...

Increasing number of patients with clinically suspected venous thromboembolism is referred to radiological departments for definitive diagnosis. A simple assay to exclude the diagnosis and avoid radiological examinations is needed. We have reported correlations between D-dimer and prothrombin fragment 1 + 2 measured in plasma and urine. To further develop an analysis based on urine, more understanding of thrombin generation in these patients is needed. The aim of this study was to compare ex vivo thrombin generation with in vivo markers in plasma and urine in patients with and without venous thromboembolism...

BACKGROUND: Early diagnosis of acute mesenteric ischemia (AMI) based on clinical judgment has been proved to be too difficult. Therefore, it is important for identifying clinical parameters that can differentiate AMI from other acute abdomen upon presentation. METHODS: We analyzed a database of 106 consecutive patients admitted to the emergency ward for suspected AMI in whom diagnosis of AMI was confirmed by laparotomy, CT angiography or mesenteric angiography. The patients' demographics, previous history, clinical signs, results of laboratory investigations and ultrasonography were collected...

Oral oestrogen increases the risk of venous thromboembolism (VTE) and increases production of sex hormone-binding globulin (SHBG) in a dose-dependent manner. SHBG has been suggested to be involved in venous thromboembolism. We examined the effects of oral ultra-low-dose oestradiol on circulating levels of SHBG and coagulation parameters, and we compared the effects to those of transdermal oestradiol. Twenty women received oral oestradiol (500 μg) every day (oral ultra-low-dose group) and 20 women received a transdermal patch (50 μg) as a transdermal group...

Ticks secrete several anti-hemostatic factors in their saliva to suppress the host innate and acquired immune defenses against infestations. Using Ixodes scapularis ticks and age-matched mice purchased from two independent commercial vendors with two different immune backgrounds as a model, we show that ticks fed on immunodeficient animals demonstrate decreased fibrinogenolytic activity in comparison to ticks fed on immunocompetent animals. Reduced levels of D-dimer (fibrin degradation product) were evident in ticks fed on immunodeficient animals in comparison to ticks fed on immunocompetent animals...
