Hammarsten [1872, 1874, 1877] first demonstrated that the rennin action on caseinogen was specific and independent of the action of the calcium salts. His explanation was that the caseinogen molecule was split up into a large molecule (Ruase) and a smaller one (Molkeneiweiss). The "Kiise" was rendered insoluble by the presence of soluble calcium salts and formed the clot. Since then little has ...

Cluster growth in a coagulating system of active particles (such as microswimmers in a solvent) is studied by theory and simulation. In contrast to passive systems, the net velocity of a cluster can have various scalings dependent on the propulsion mechanism and alignment of individual particles. Additionally, the persistence length of the cluster trajectory typically increases with size. As a ...

background: electrocoagulation is a technique involving the electrolytic addition of coagulating metal ions directly from sacrificial electrodes. these ions coagulate with turbidity agents in the water, in a similar manner to the addition of coagulating chemicals such as alum and ferric chloride, and allow the easier removal of the pollutants. purpose of this study was to conduct experimental i...

The major coagulating fibrinogenase of Deinagkistrdon acutus venom, designated acutobin, was purified by anion-exchange chromatography, gel filtration and reverse-phase HPLC. Approximately 80% of its protein sequence was determined by sequencing the various fragments derived from CNBr cleavage and digestion with endoprotease. Extensive screening of the venom gland cDNA species after amplificati...
