Fibrinogen-activating enzymes, widely distributed in Crotalidae and Viperidae venoms, are single-chain glycosylated serine proteases that display high macromolecular selectivity and are often referred to as thrombin-like enzymes (TLEs). TLEs serve as structural models to extend our understanding of the structure-function relationships of blood coagulation factors, have been clinically used for ...

This paper reports the potential of watermelon seed as a natural coagulant for water treatment. It was aimed at identifying watermelon seed as a possible replacement for alum and other synthetic polyelectrolytes in treating water. Laboratory scale studies using jar test experiments were performed on medium turbid water to determine the effect of dosage, pH stirring time and speed on coagulation...

Landfill leachate may cause environmental problems if it is not properly managed and treated. An appropriate treatment process of landfill leachate often involves a combination of physical, chemical and biological methods to obtain satisfactory results. In this study, coagulation-flocculation was proposed as a pretreatment stage of partially stabilized landfill leachate prior to submerged biolo...

Polymerized inorganic coagulants are increasingly being used in the water supply and wastewater treatment process, yet there is limited research on the development of polytitanium coagulants. The aim of this study is to synthesize polytitanium chloride (PTC) coagulants and investigate their coagulation behavior and floc characteristics for humic acid removal in comparison to polyaluminum chlori...

Excessive pro-coagulant and decreased fibrinolytic activities in the alveolar compartment have been repeatedly documented for inflammatory and fibrotic lung diseases. The current authors determined the contribution of different resident lung cells to the altered local production of coagulation- and fibrinolysis-system components in bleomycin-injured mouse lungs via cell-specific and quantitativ...

The aim of the study was to estimate effectiveness ultrasonic coagulation aiding. effect ultrasound exposure alone and associated systems (ultrasound exposure/coagulant) on contamination natural water examined. evaluation test results based changes in indicators, such as TOC, color, turbidity, electrokinetic potential. Three different coagulants were used tests systems. included basic processes...

Critically ill patients often have systemic activation of both inflammation and coagulation. Increasing evidence points to an extensive cross-talk between these two systems, whereby inflammation not only leads to activation of coagulation, but coagulation also considerably affects inflammatory activity. The intricate relationship between inflammation and coagulation may have major consequences ...

Abstract Wastewater issues became a complex challenge in the world. There are several methods wastewater treatment, such as chemical, physical, biological, and combination of each method. However, process has advantages disadvantages. The physicochemical common used adsorption coagulation. Adsorption coagulation excellent to remove pollutants. is greatly influenced by pH, adsorbent dose, temper...
