Angiomyoma
|
D018229 |
[A benign tumor consisting of vascular and smooth muscle elements.

|
Angioplasty
|
D017130 |
[Reconstruction or repair of a blood vessel, which includes the widening of a pathological narrowing of an artery or vein by the removal of atheromatous plaque material and/or the endothelial lining as well, or by dilatation (BALLOON ANGIOPLASTY) to compress an ATHEROMA. Except for ENDARTERECTOMY, usually these procedures are performed via catheterization as minimally invasive ENDOVASCULAR PROCEDURES.

Angioplasty, Balloon
|
D000800 |
[Use of a balloon catheter for dilation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of BALLOON DILATION in coronary arteries, ANGIOPLASTY, BALLOON, CORONARY is available.

Angioplasty, Balloon, Coronary
|
D015906 |
[Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.

|
Angioplasty, Balloon, Laser-Assisted
|
D017222 |
[Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.

Angioplasty, Laser
|
D016342 |
[A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).

Angiopoietin-1
|
D042683 |
[The first to be discovered member of the angiopoietin family. It may play a role in increasing the sprouting and branching of BLOOD VESSELS. Angiopoietin-1 specifically binds to and stimulates the TIE-2 RECEPTOR. Several isoforms of angiopoietin-1 occur due to ALTERNATIVE SPLICING of its mRNA.
] |
|
Angiopoietin-2
|
D042702 |
[An angiopoietin that is closely related to ANGIOPOIETIN-1. It binds to the TIE-2 RECEPTOR without receptor stimulation and antagonizes the effect of ANGIOPOIETIN-1. However its antagonistic effect may be limited to cell receptors that occur within the vasculature. Angiopoietin-2 may therefore play a role in down-regulation of BLOOD VESSEL branching and sprouting.

Angiopoietin-like 4 Protein
|
D000075803 |
[A secreted angiopoietin-like protein expressed under hypoxic conditions by ENDOTHELIAL CELLS. It inhibits cell proliferation, cell migration, and tubule formation; the inactive form accumulates in the endothelial EXTRACELLULAR MATRIX, reducing vascular leakage. ANGPTL4 has direct roles in regulating glucose and lipid metabolism, as well as INSULIN SENSITIVITY, and may also function as a regulator of angiogenesis and tumorigenesis.

|
Angiopoietin-like Proteins
|
D000075802 |
[A family of proteins that is structurally similar to ANGIOPOIETINS but do not bind angiopoietin receptors. They are characterized by an amino-terminal coiled-coil domain, a linker region, and a carboxy-terminal FIBRINOGEN-like domain with the exception of ANGPTL8, which lacks the fibrinogen-like domain. They function in a variety of developmental and physiological processes, including INFLAMMATION, lipid metabolism, hematopoietic stem cell activity, and cancer metastasis.

|
Angiopoietins
|
D042682 |
[A family of structurally-related angiogenic proteins of approximately 70 kDa in size. They have high specificity for members of the TIE RECEPTOR FAMILY.

|
Angioscopes
|
D020677 |
[Endoscopes used for viewing the interior of blood vessels.
] |
|
Angioscopy
|
D017546 |
[Endoscopic examination, therapy or surgery performed on the interior of blood vessels.
] |
|
Angiostatic Proteins
|
D043165 |
[Proteins that specifically inhibit the growth of new blood vessels (ANGIOGENESIS, PHYSIOLOGIC).
] |
|
Angiostatins
|
D043168 |
[Circulating 38-kDa proteins that are internal peptide fragments of PLASMINOGEN. The name derives from the fact that they are potent ANGIOGENESIS INHIBITORS. Angiostatins contain four KRINGLE DOMAINS which are associated with their potent angiostatic activity.
] |
|
Angiostrongylus
|
D000801 |
[A genus of parasitic nematodes of the superfamily METASTRONGYLOIDEA. Two species, ANGIOSTRONGYLUS CANTONENSIS and A. vasorum, infest the lungs of rats and dogs, respectively. A. cantonensis is transmissible to man where it causes frequently fatal infection of the central nervous system.
] |
|
Angiostrongylus cantonensis
|
D017185 |
[A species of parasitic nematodes distributed throughout the Pacific islands that infests the lungs of domestic rats. Human infection, caused by consumption of raw slugs and land snails, results in eosinophilic meningitis.

Angiotensin Amide
|
D000802 |
[The octapeptide amide of bovine angiotensin II used to increase blood pressure by vasoconstriction.
] |
|
Angiotensin I
|
D000803 |
[A decapeptide that is cleaved from precursor angiotensinogen by RENIN. Angiotensin I has limited biological activity. It is converted to angiotensin II, a potent vasoconstrictor, after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME.
] |
|
Angiotensin II
|
D000804 |
[An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.
