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...

The efficiency of Moringa oleifera (MO) seeds as a natural coagulant in the coagulation/flocculation process, followed by nanofiltration (NF) for the removal of cyanobacterial cells and cyanotoxins is investigated. "Synthetic water" prepared for the tests comprised de-ionized water with an inoculum of microcystis protocystis cells to obtain turbidity within the 50-450 NTU range. Methodology fol...

A plasma protein required for the support of ristocetininduced platelet aggregation was isolated from antihemophilic factor concentrate and radiolabeled with 1251. A double-antibody radioimmunoassay was developed, with use of specific rabbit anti-Vill related antigen serum and goat anti-rabbit globulin. The assay is sensitive, reproducible, and technically simple to perform. Values obtained in ...

Pulp and paper mill effluent is highly polluting and is a subject of great environmental concern. In the present research we studied the removal of chemical oxygen demand (COD) and colour from paper mill effluent, using the coagulation process. A batch coagulation study was conducted using various coagulants such as aluminium chloride (AlCl3), polyaluminium chloride (PAC) and copper sulphate (C...

Using the substrate H-D-Pro-Phe-Arg-p-nitroanilide-HCl, an amidolytic assay was designed to measure prekallikrein in plasma. At a substrate concentration of 1 mM (Km = 0.2 mM), the amidolysis of purified kallikrein at 1 coagulant unit/ml was observed to be 2.47 mumole/min/ml. Conditions for plasma prekallikrein activation were optimized to approach complete activation when compared to the amido...

Recent studies have shown that endothelial protein C receptor (EPCR) polymorphisms and soluble EPCR levels are associated with thrombotic diseases. It is unknown whether membrane EPCR (mEPCR) heterozygosity and/or physiologically elevated sEPCR levels directly impact the hemostatic balance and the outcome of endotoxemia. In these studies, thrombin infusion experiments revealed that EPCR heteroz...
