In vitro evaluation of prothrombin complex concentrates in a thrombin generation assay, using DAPA and purified components of the prothrombinase complex, demonstrated significant levels of coagulant-active "phospholipid replacing" activity. Quantification of this activity showed a significant correlation (r = 0.8747, p less than 0.01) with thrombogenicity measured in vivo in a stasis model in r...

Many substances of plant origin are extracted for use in the primary treatment domestic wastewater. In most cases, they used as coagulating and flocculating agents derived from seeds, leaves, bark or sap, roots, fruits trees plants. this research, Cassia fistula seed was evaluated removal turbidity color wastewater a pumping station city Cartagena (Colombia). The optimal dose C. powder determin...

Abstract Coagulants are essential in purifying raw water for drinking safety consumers. Commonly, aluminium sulphate, a chemical coagulant, is used treatment. However, long-term usage, coagulants can be considered toxic and harmful to the environment due accumulation of this substance pipeline system, which create severe health issues if consumed. The natural plant-based coagulant substitute su...

BACKGROUND AND OBJECTIVES A high level of coagulant factor VIII is a well known risk factor for venous thromboembolism, but most studies have enrolled patients under 70 years old. This study aimed to test the hypothesis that an association also exists in the elderly. DESIGN AND METHODS This hospital-based case-referent study took place at the Department of Internal Medicine and Chest Diseases...

The need to ameliorate some of the inherent limitations in the use of alum in water purification engendered these studies. Synthetic water of varying turbidities (50, 100, 300 NTU) and varying pHs (2, 3, and 4), but low alkalinity were prepared. The results from the different studies showed that water of lower residual turbidity could be got from the use of 50% of optimum alum dose when combine...
