Angiosarcoma of skin
Cutaneous angiosarcoma is a rare, aggressive vascular sarcoma of the skin, mainly of the elderly head and scalp, or secondary to radiation or lymphedema; 5-year survival is roughly 30% and treatment is surgery plus radiotherapy.
Angioscopes
Angioscopes are fiber-optic endoscopic catheters (angioscopy) that take true-color video images inside blood vessels. Oldest coronary optical imaging tool; FDA-approved but mainly research use; requires balloon occlusion and saline flushing.
Angioscopy
Angioscopy, or coronary angioscopy, is an endoscopic imaging technique in which a fiber-optic catheter camera directly views blood vessel surfaces, chiefly coronary arteries, for plaque and thrombus.
Angiosperm terpene synthase clades (TPS-a, TPS-b, TPS-c, TPS-g)
The angiosperm terpene synthase clades TPS-a, TPS-b, TPS-c, and TPS-g are subfamilies of plant terpene synthase enzymes; TPS-a, b, and g occur only in flowering plants.
Angiostrongyliasis
Angiostrongyliasis, or rat lungworm disease, is caused by the nematodes Angiostrongylus cantonensis (eosinophilic meningitis) and A. costaricensis (abdominal form), acquired by eating raw snails, slugs, or paratenic hosts; over 7,000 cases recorded worldwide.
Angiostrongylus cantonensis
Angiostrongylus cantonensis, the rat lungworm, is a metastrongyloid nematode causing eosinophilic meningitis in humans, acquired from snails or slugs; described by Chen in 1935 in Guangzhou, now spread to about 30 countries.
Angiostrongylus vasorum
Angiostrongylus vasorum, the French heartworm, is a metastrongyloid nematode of dog and fox pulmonary arteries and right heart, transmitted by snails and slugs, causing pneumonia and coagulopathy in dogs and spreading across Europe.
Angiotensin
Angiotensin, especially angiotensin II, is the effector peptide of the renin-angiotensin system regulating blood pressure; discovered 1898-1958, targeted by ACE inhibitors and ARBs, whose comparative cardiovascular outcomes differ across trial populations.
Angiotensin II
Angiotensin II is an octapeptide hormone of the renin-angiotensin-aldosterone system that raises blood pressure by constricting blood vessels, and its synthetic form is an intravenous drug, Giapreza, for septic shock.
Angiotensin II receptor blocker
Angiotensin II receptor blocker (ARB) is a class of drugs called sartans that lowers blood pressure by blocking angiotensin II receptors. The first was losartan, approved in 1995.
Angiotensin-(1-7)
Angiotensin-(1-7) (Ang-(1-7)) is an endogenous heptapeptide of the renin–angiotensin system, formed chiefly by ACE2 from angiotensin II, that counteracts angiotensin II through the Mas receptor and shows protective cardiovascular effects in animal models.
Angiotensin-converting enzyme
Angiotensin-converting enzyme (ACE, EC 3.4.15.1) is a zinc-dependent peptidyl-dipeptidase with two catalytic domains that converts angiotensin I to angiotensin II, inactivates bradykinin, and is targeted by captopril-like antihypertensive drugs.
Angiotensin-converting enzyme 2
ACE2 (angiotensin-converting enzyme 2, ACEH) is a zinc carboxypeptidase discovered in 2000 that converts angiotensin II to vasodilatory Ang-(1-7) and serves as the SARS-CoV and SARS-CoV-2 entry receptor.
Angiotensinogen
Angiotensinogen (AGT) is a plasma glycoprotein produced mainly by the liver and encoded by the AGT gene on chromosome 1, serving as the only known substrate of renin.
