WebbThe plasma coagulation system in mammalian blood consists of a cascade of enzyme activation events in which serine proteases activate the proteins (proenzymes and … WebbInterferon (IFN)-γ is a cytokine known for its immunomodulatory and anti-proliferative action. In the liver, IFN-γ can induce hepatocyte apoptosis or inhibit hepatocyte cell cycle progression.This article reviews recent mechanistic reports that describe how IFN-γ may direct the fate of hepatocytes either towards apoptosis or a cell cycle arrest. ...

WebbWhen damage till small blood vessels and covered occurs, the body controls blood loss via physiological processes referred in as hemostasis. In vivo, hemostasis depends on an interaction between the plasma–based coagulation chain, platelets, press that endothelium are blood vessels. In the clinical labs, are vitro analytical assays are … WebbTwo Phases of Coagulation It can be helpful to consider secondary hemostasis as a process that occurs in two distinct phases. The initiation phase, triggered by the release of tissue factor into the bloodstream, results in the production of a relatively small amount of thrombin through the extrinsic pathway.

A basic knowledge of hemostasis is necessary to evaluate various disease processes in horses. Initial injury to the vascular endothelium results in local vasoconstriction and formation of a platelet plug.
