Mindblown: a blog about philosophy.

Yeast infection of the mouth and throat, characterized by patches of white, caused by the fungus Candida albicans . Yeast are part of the normal flora in the mouth. They ordinarily do not cause symptoms. Certain conditions, such as antibiotic use, can disturb the natural balance of microorganisms in the mouth and allow the overgrowth of Candida to cause thrush. Overgrowth of Candida albicans can…

A substance made by platelets that causes blood clotting and constriction of blood vessels. It also encourages platelet aggregation. There are two thromboxanes. Thromboxane A2 (TXA2) is active but is very unstable and has a half-life of only 30 seconds before it undergoes hydrolysis to form thromboxane B2 (TXB2) which is inactive. The thromboxanes are derived from arachidonic…

A life-threatening disease involving embolism and thrombosis (plugging) of the small blood vessels in the brain and kidneys and other organs. It is most commonly caused by inhibition of the enzymes ADAMTS13 which normally serves to break up a blood protein called Von Willebrand Factor into smaller pieces. TTP is characterized by platelet microthrombi (tiny traveling clots composed of platelets, the…

The formation or presence of a blood clot in a blood vessel. The vessel may be any vein or artery as, for example, in a deep vein thrombosis or a coronary (artery) thrombosis. The clot itself is termed a thrombus. If the clot breaks loose and travels through the bloodstream, it is a thromboembolism. Thrombosis, thrombus, and the prefix thrombo- all…

Inflammation of a vein that occurs when a blood clot forms.

The tendency to form thromboses (blood clots in arteries and veins).

Formation in a blood vessel of a clot (thrombus) that breaks loose and is carried by the blood stream to plug another vessel. The clot may plug a vessel in the lungs (pulmonary embolism), brain (stroke), gastrointestinal tract, kidneys, or leg. Thromboembolism is a significant cause of morbidity (disease) and mortality (death), especially in adults. Treatment may involve anticoagulants (blood…

A low platelet count. Platelets are irregular, disc-shaped element in the blood that assists in blood clotting. thrombocytopenia can arise due to decreased production of platelets in the bone marrow or increased breakdown of platelets in the bloodstream, spleen, or liver. Thrombocytopenia is characterized by easy bruising and increased bleeding.

A platelet. Crucial to normal blood clotting. Although platelets are sometimes classed as blood cells, they are not. They are fragments of a large cell called a megakaryocyte (literally, a large cell).

The throat is the anterior (front) portion of the neck beginning at the back of the mouth, consisting anatomically of the pharynx and larynx. The throat contains the trachea and a portion of the esophagus.
