Protein-C inhibitor (PCI) is a newly described plasma inhibitor directed against a vitamin-K-dependent serine protease, activated protein-C, which is involved in the inactivation of factor V and factor VIII. Marlar and Griffin have reported that PCI activity is absent in the plasma of patients with congenital combined factor V/VIII deficiency. We have measured the levels of PCI in the plasma of...

Volumetric diameters Dv and specific surface area SpS of sludge particles formed during chemical coagulation and electrocoagulation of sewage were determined. The obtained aggregate-flocs differed substantially in both Dv and SpS values. The differences in Dv and SpS values of the analyzed particles were interpreted based on theoretical models for expanding aggregates. The most uniform particle...

The application of peat water may be able to address the problem scarcity. This study used Moringa oleifera seed as a coagulant via jar tests in series coagulation-flocculation processes remove humic substances (HS) from water. Characterisations were performed on and GC–MS analysis showed that oleic acid octadecanoic are two main parts seeds help coagulation process. FTIR revealed consists hydr...

In this study, a biological coagulant (gum) extracted from moringa seeds is produced as to treat Reactive Yellow 145 (RY145) and Red 194 (RR194). The material's properties are determined by scanning electron microscopy (SEM) FTIR. SEM images show that the surface structure of gum has appearance relatively fine pores homogenously distributed particles on surface. FTIR spectra indicate prepared m...

Point of use (POU) household water treatment is increasingly being adopted as a solution for access to safe water. Non-tuberculous Mycobacteria (NTM) are found in water, but there is little research on whether NTM survive POU treatment. Mycobacteria may be removed by multi-barrier treatment systems that combine processes such as coagulation, settling and disinfection. This work evaluated remova...

The same protein has coagulant or fibrinolytic activity depending on the pH or temperature value. The protein has coagulant action in low pH and temperature or fibrinolytic activity in high pH and temperature. A same protein has own autonomy to develop coagulant or lytic activity, depending of its environment. Many diseases may be explained by changes in the internal environments as pH and temp...

Ischemic heart disease is caused by a combination of and interaction between a number of genetic and environmental factors. In a study of a group of healthy men from the United Kingdom, such an interaction was identified between the levels of plasma triglycerides and genetic variation determining plasma levels of factor VII, a clotting factor that is associated with risk of ischemic heart disea...

Crotalus durissus cumanensis, a rattlesnake endemic to Colombia and Venezuela, is considered one of the most lethal snake species in Latin America. The aim of the present study was to compare the protein content and biological activity of the venom obtained from eight specimens of C. durissus cumanensis, namely two adults from different localities of Colombia and six offspring born in captivity...

BACKGROUND Inhibition of blood coagulation appears to be an important therapeutic strategy to improve the outcome in sepsis. However, the beneficial effect of anticoagulant treatment in sepsis is solely based on experimental data using inhibitors of the extrinsic coagulant pathway. The role of the intrinsic pathway of coagulation in the pathogenesis of sepsis has not been explored yet. OBJECT...
