this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

Introduction: The most important environmental problem of automotive industries is the produced wastewater due to its various processes. The flocculation and coagulation along with chemical sequestration are among important processes for removing contaminants from wastewaters. The aim of this study is to investigate the efficiency of coagulation and flocculation process along with chemical sequ...

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.

PURPOSE To establish the optimal protocol of heparin administration during interventional neuroradiology. METHODS We assessed 100 cases of neuroangiography, including endovascular surgery, and measured activated coagulation time before and 5 minutes after heparin administration, and before and 5 minutes after protamine neutralization. In some cases actual heparin concentration was assayed usi...

Background: The liver is the cornerstone of the coagulation system. The physiology of blood coagulation is closely linked to liver function as the liver synthesizes most of the factors of the coagulation cascade and fibrinolytic proteins. Objective: The objective of this study was to evaluate coagulation abnormalities associated with chronic liver diseases and determine the coagulation abnormal...

Standard coagulation tests have a low specificity and sensitivity for diagnosing disseminated intravascular coagulation. The aim of this study was to determine whether whole blood thromboelastometry (TEM) detects lipopolysaccharide (LPS)-induced changes in coagulation. Blood samples from 10 pigs were drawn at baseline, before and at the end of LPS infusion and 2, 3, 4 and 5 h after the start of...

Zinc oxide nanoparticles (ZnO NPs) have many biomedical applications such as chemotherapy agents, vaccine adjuvants, and biosensors but its hemocompatibility is still poorly understood, especially in the event of direct contact of NPs with blood components. Here, we investigated the impact of size and surface functional groups on the platelet homeostasis. ZnO NPs were synthesized in two differe...
