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...

Introduction: The removal of organic precursors of disinfection byproducts (DBPs), i.e. natural organic matter (NOM), prior to disinfection is considered as the most effective approach to minimise the formation of DBPs. Trihalomethanes (THMs) as the main group of DBPs are categorized and considered to have the potentiality of increasing the rate of liver, kidney and CNS adverse effects. Methods...

We evaluated systemic alterations to the blood coagulation system that occur during a coronary thrombotic event. Peripheral blood coagulation in patients with acute coronary thrombosis was compared with that in people with stable coronary artery disease (CAD). Blood coagulation and platelet activation at the microvascular injury site were assessed using immunochemistry in 28 nonanticoagulated p...

The objective of this research was to optimize the coagulation-flocculation process for abattoir wastewater by utilizing a bio-coagulant derived from Carica Papaya seed (CPS). (CPC) extracted using 2M NaCl solution, and carried out bench scale jar test. Applying design expert (13.0.5.0), 23 full factorials with 5 center points, effects three factors: coagulant dosage (X1), pH (X2), temperature ...

This study aims to examine the decomposition method of liquid waste in home industry, especially tofu by using non-thermal plasma and electrocoagulant methods that are environmentally friendly with low energy. In this study, method, electro-coagulant a combination both (electro-coagulant followed method) were used decompose industry. The results showed electrocoagulation was most effective redu...

Industrial effluents are a menace to the environment and the fact that their characteristics vary from industry-to-industry only adds to the complex challenge they offer to the engineers and scientists. Resource-efficient and environment-friendly solutions to this hazard are a call of the hour. Coagulation, by synthetic chemicals, has been used as a cost-effective and efficient method for manag...

In this present study the dissolved air flotation (DAF) system was investigated for the treatment of Kermanshah Oil Refinery wastewater. The effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (COD) removal was examined experimentally. All the experiments were done under a...

Plantago ovata is a medicinal plant of plantain, Plantaginaceae, family used to treat intestinal disorders and stomach diseases. P. ovata grain has relieving effects and healing inflammation and irritation of the mucous layer of stomach and duodenal ulcer. Beside the medicinal benefits, this plant is useful for water turbidity removal. Coagulation and flocculation are important processes in wat...

ABSTRACT Background and objective: Milk and dairy industries wastewater are considered the most polluted effluents, and if discharged without treatment into the environment, can cause serious environmental problems.  In this study, effects of aeration time and lime coagulant on SBR efficiency were investigated. Materials and Method: Two Parallel reactors with a volume of  20 L w...

Background and purpose: Vipera lebetina lives in different areas in Iran, and its venom contains a variety of proteins with coagulant and anticoagulant activities. Fibrinolytic enzymes could have a therapeutic role in dissolution of blood clots, so, this study aimed at separating the venom components of Iranian V. lebetina and detecting its anticoagulant activity. Materials and methods: In thi...
