asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Congenital factor X deficiency is a rare autosomal recessive bleeding disorder that presents with variable bleeding tendency and prolonged coagulation tests, prothrombin time, and partial thromboplastin time. Thromboembolic events have not been reported in patients with factor X deficiency yet. Herein, we report a patient with factor X deficiency who had recurrent venous thromboembolic events.
In this study, the Acid Black 1 dye containing effluent collected from a dyeing unit was examined with the alginate extracted from the marine brown algae, Sargassum sp. for its removal. Batch experiments were carried out using standard Jar test apparatus. Fourier Transform InfraRed (FT-IR) Spectroscopy and Scanning Electron Microscopy (SEM) techniques were used to characterize the raw algin...
Backgrounds and Aims: Methylglyoxal (MGO) is an –α, β dicarbonyl aldehyde inevitably produced from triose-phosphate intermediates of glycolysis, and amino acid. Increased MGO in blood leads to alterations in coagulation, clot permeability and thus, atherosclerosis in children with diabetes; however, the precise mechanism is not clear. The present study aimed to compare differen...
Background & Objectives: In sepsis, enhanced fibrin formation, impaired fibrin degradation, and intravascular fibrin deposition lead to a prothrombotic state. The current study aimed at measuring various coagulation parameters to predict an early marker for disseminated intravascular coagulation (DIC). Methods: The current prospective s...
Acquired coagulation factor inhibitor is a rare coagulation disorder. We herein report a patient with acquired factor V inhibitor showing a decrease in multiple coagulation factor activities. A high titer of factor V inhibitor presumably led to a marked inhibition of factor V activity in the specific factor-deficient plasma used in coagulation factor activity assays based on either an activated...

The paper presents the results of study coagulation process whole blood with anticoagulant using method laser speckle correlation. clotting time dependence curves correlation coefficient have been presented and discussed. Analyzing changing trend these is possible to assess time, which prove capability for determining diseases coagulation.
introduction: the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. these inhibitors are necessary to prevent thromboembolism. hereditary deficiency of inhibitors is the main cause of alteration in balance between the anti-clotting and the formation of thrombin. patients with this abnormality are susceptible to venous thromboembolism (vte). two major clinica...
Afibrinogenemia or hypofibrinogenemia is a quantitative defect in fibrinogen. It is a rare disease with estimated frequency of 1 in 1,000,000 population. Routine preoperative screening tests of coagulation disorders are insufficient to detect subtle disorders of fibrinogen. Herein, we report a child who was supposed to undergo open cardiac surgery for a large atrial septal defect. Preoperative ...
