D010482 |
[Acute or chronic inflammation of tissues surrounding the apical portion of a tooth, associated with the collection of pus, resulting from infection following pulp infection through a carious lesion or as a result of an injury causing pulp necrosis. (Dorland, 27th ed)

D010483 |
[Diseases of the PERIAPICAL TISSUE surrounding the root of the tooth, which is distinguished from DENTAL PULP DISEASES inside the TOOTH ROOT.

|
Periapical Granuloma
|
D010484 |
[Chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment.
] |
|
Periapical Periodontitis
|
D010485 |
[Inflammation of the PERIAPICAL TISSUE. It includes general, unspecified, or acute nonsuppurative inflammation. Chronic nonsuppurative inflammation is PERIAPICAL GRANULOMA. Suppurative inflammation is PERIAPICAL ABSCESS.

|
Periapical Tissue
|
D010486 |
[Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone.

|
Periaqueductal Gray
|
D010487 |
[Central gray matter surrounding the CEREBRAL AQUEDUCT in the MESENCEPHALON. Physiologically it is probably involved in RAGE reactions, the LORDOSIS REFLEX; FEEDING responses, bladder tonus, and pain.

|
Periarthritis
|
D010489 |
[Inflammation of the tissues around a joint. (Dorland, 27th ed)
] |
|
Pericardial Effusion
|
D010490 |
[Fluid accumulation within the PERICARDIUM. Serous effusions are associated with pericardial diseases. Hemopericardium is associated with trauma. Lipid-containing effusion (chylopericardium) results from leakage of THORACIC DUCT. Severe cases can lead to CARDIAC TAMPONADE.

|
Pericardial Fluid
|
D000069236 |
[Watery fluid produced in the serous and visceral pericardium surrounding the surface of the HEART.
] |
|
Pericardial Window Techniques
|
D010491 |
[Surgical construction of an opening or window in the pericardium. It is often called subxiphoid pericardial window technique.
] |
|
Pericardiectomy
|
D010492 |
[Surgical excision (total or partial) of a portion of the pericardium. Pericardiotomy refers to incision of the pericardium.
] |
|
Pericardiocentesis
|
D020519 |
[Puncture and aspiration of fluid from the PERICARDIUM.
] |
|
Pericarditis
|
D010493 |
[Inflammation of both the PERICARDIUM and the PLEURA.
, Inflammation of the PERICARDIUM from various origins, such as infection, neoplasm, autoimmune process, injuries, or drug-induced. Pericarditis usually leads to PERICARDIAL EFFUSION, or CONSTRICTIVE PERICARDITIS.
] |
|
Pericarditis, Constrictive
|
D010494 |
[Inflammation of the PERICARDIUM that is characterized by the fibrous scarring and adhesion of both serous layers, the VISCERAL PERICARDIUM and the PARIETAL PERICARDIUM leading to the loss of pericardial cavity. The thickened pericardium severely restricts cardiac filling. Clinical signs include FATIGUE, muscle wasting, and WEIGHT LOSS.
] |
|
Pericarditis, Tuberculous
|
D010495 |
[INFLAMMATION of the sac surrounding the heart (PERICARDIUM) due to MYCOBACTERIUM TUBERCULOSIS infection. Pericarditis can lead to swelling (PERICARDIAL EFFUSION), compression of the heart (CARDIAC TAMPONADE), and preventing normal beating of the heart.
] |
|
Pericardium
|
D010496 |
[A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.

|
Pericoronitis
|
D010497 |
[Inflammation of the gingiva surrounding the crown of a tooth.
] |
|
Pericytes
|
D020286 |
[Unique slender cells with multiple processes extending along the capillary vessel axis and encircling the vascular wall, also called mural cells. Pericytes are imbedded in the BASEMENT MEMBRANE shared with the ENDOTHELIAL CELLS of the vessel. Pericytes are important in maintaining vessel integrity, angiogenesis, and vascular remodeling.

|
Perilipin-1
|
D000070778 |
[A lipid droplet protein that is expressed primarily by ADIPOCYTES of WHITE ADIPOSE TISSUE and BROWN ADIPOSE TISSUE. It co-localizes with MACROPHAGES and FOAM CELLS of artherosclerotic lesions and stabilizes LIPID DROPLETS by inhibiting HORMONE SENSITIVE LIPASE. It may also protect TRIGLYCERIDES against hydrolysis within the PLASMA MEMBRANE and modulate CHOLESTEROL ESTER HYDROLASE activity.
] |
|
Perilipin-2
|
D000070780 |
[A perilipin that is expressed by many different cell types. It binds FATTY ACIDS and CHOLESTEROL, stabilizes TRIGLYCERIDES, and localizes to both the surface and hydrophobic core of LIPID DROPLETS, as well as the ENDOPLASMIC RECTICULUM and PLASMA MEMBRANE in MACROPHAGES. It also plays a central role in the biogenesis of lipid droplets and FOAM CELLS and is highly expressed by macrophages at atherosclerotic lesions in human arteries along with the INFLAMMATION markers TNF-ALPHA; MCP-1 RECEPTOR; and IL-6.
