Changing concepts of clotting mechanism of blood: From cascade model to cell-based modelVelou, M. SenthilAhila, E.International Archives of Integrated Medicine
Blood clotting, or coagulation, is a biological process that stops bleeding. It's vital that blood clots when we have a surface injury that breaks blood vessels. Clotting can prevent us from bleeding to death and protect us from the entry of bacteria and viruses. Clots also form inside our ...
Interestingly, eRNA also acts as a cofactor of internal blood clotting pathway, mainly factors XI and XII, favoring a prothrombotic phenotype [57–59]. These functions of eRNA contribute deeply to ischemic injury following myocardial infarction. The contribution of eRNA to ischemic injury has been ...
Gold nanoparticles allow to turn blood-clotting cascade on or offBy Anne Trafton, MITPlos One
Describe the events of the clotting mechanism, including both intrinsic and extrinsic pathways. What are the functions of platelets? What is meant by the term anemia? A. Anemia always results from some very simple cause. B. Anemia exists when the platelet count is so low that blood does not...
Over the past several decades, however, it has been increasingly recognized that initiation of coagulation is an integral and consistent element of the local and systemic response to inflammatory stimuli. The precise mechanism whereby coagulation contributes to the full expression of inflammation is an ...

8.1), followed by a cascade of complement proteins that activate each other through a complex mechanism, which ends up with the virus being coated and inactivated (opsonization), thus interfering with the ability of the virus to interact with the membrane of the cells it is targeting and ...
The emergence and continued spread of SARS-CoV-2 have resulted in a public health emergency across the globe. The lack of knowledge on the precise mechanism of viral pathogenesis is impeding medical intervention. In this study, we have taken both in silico and in vitro experimental approaches to...
(the process of blood clotting and the mobilization of glycogen being two others) where such complex sequences operate. It has been argued that cascade systems are sensitive ways of amplifying an initial small biological signal. Because each component in the cascade is a catalytic entity, one ...
