Green, leafy vegetables and some root vegetables (such as beetroot) have high concentrations of nitrate. [10] When eaten and absorbed into the bloodstream, nitrate is concentrated in saliva (about 10-fold) and is reduced to nitrite on the surface of the tongue by a biofilm of commensal facultative anaerobic bacteria.

Fibrinolysis is a process that prevents blood clots from growing and becoming problematic. [1] Primary fibrinolysis is a normal body process, while secondary fibrinolysis is the breakdown of clots due to a medicine, a medical disorder, or some other cause. [2] In fibrinolysis, a fibrin clot, the product of coagulation, is broken down. [3]
Streptolysin O is an oxygen-sensitive cytotoxin secreted by most Group A streptococcus (GAS) and Streptococcus dysgalactiae; it interacts with cholesterol in the membrane of eukaryotic cells (mainly red and white blood cells, macrophages, and platelets), usually resulting in β-hemolysis under the surface of blood agar. Streptolysin S is an ...
The inflammation surrounding the vein and compression of the vein may lead to blood clot formation. Pieces of the potentially infected clot can break off and travel through the right heart into the lungs as emboli, blocking branches of the pulmonary artery that carry deoxygenated blood from the right side of the heart to the lungs. [citation ...
Thromboregulation is the series of mechanisms in how a primary clot is regulated. These mechanisms include, competitive inhibition or negative feedback. It includes primary hemostasis, which is the process of how blood platelets adhere to the endothelium of an injured blood vessel.
The treatments to prevent the formation of blood clots are balanced against the risk of bleeding. [5] One of the goals of blood clot prevention is to limit venous stasis as this is a significant risk factor for forming blood clots in the deep veins of the legs. [6] Venous stasis can occur during the long periods of not moving.
Fibrin (also called Factor Ia) is a fibrous, non-globular protein involved in the clotting of blood. It is formed by the action of the protease thrombin on fibrinogen, which causes it to polymerize. The polymerized fibrin, together with platelets, forms a hemostatic plug or clot over a wound site.
