Polycystic Ovary Syndrome
|
D011085 |
[A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.

D011086 |
[An increase in the total red cell mass of the blood. (Dorland, 27th ed)

|
Polycythemia Vera
|
D011087 |
[A myeloproliferative disorder of unknown etiology, characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume, associated frequently with splenomegaly, leukocytosis, and thrombocythemia. Hematopoiesis is also reactive in extramedullary sites (liver and spleen). In time myelofibrosis occurs.

Polydeoxyribonucleotides
|
D011089 |
[A group of 13 or more deoxyribonucleotides in which the phosphate residues of each deoxyribonucleotide act as bridges in forming diester linkages between the deoxyribose moieties.

Polydioxanone
|
D016687 |
[An absorbable suture material used also as ligating clips, as pins for internal fixation of broken bones, and as ligament reinforcement for surgically managed ligament injuries. Its promising characteristics are elasticity, complete biodegradability, and lack of side effects such as infections.

Polydipsia
|
D059606 |
[Excessive thirst manifested by excessive fluid intake. It is characteristic of many diseases such as DIABETES MELLITUS; DIABETES INSIPIDUS; and NEPHROGENIC DIABETES INSIPIDUS. The condition may be psychogenic in origin.

|
Polydipsia, Psychogenic
|
D059607 |
[A clinical disorder characterized by excessive fluid intake (polydipsia); HYPONATREMIA; and POLYURIA in SCHIZOPHRENIA and other psychiatric disorders. Impaired water metabolism in psychogenic polydipsia can result in WATER INTOXICATION.

Polydnaviridae
|
D018071 |
[A family of insect viruses isolated from endoparasitic hymenopteran insects belonging to the families Ichneumonidae and Braconidae. The two genera are Ichnovirus and Bracovirus.

Polyelectrolytes
|
D000071228 |
[Naturally-occurring or artificially made water-soluble POLYMERS whose repeating units are ionizable. Polyelectrolytes demonstrate attributes that are typical of salts, such as electrical conductivity, and typical of polymers, such as viscosity.
, A class of water-soluble polyelectrolytes with pi-delocalized structure and functional ionic properties used for fluorescent staining of cells and as semi-conducting materials in electronic devices.

Polyendocrinopathies, Autoimmune
|
D016884 |
[Autoimmune diseases affecting multiple endocrine organs. Type I is characterized by childhood onset and chronic mucocutaneous candidiasis (CANDIDIASIS, CHRONIC MUCOCUTANEOUS), while type II exhibits any combination of adrenal insufficiency (ADDISON'S DISEASE), lymphocytic thyroiditis (THYROIDITIS, AUTOIMMUNE;), HYPOPARATHYROIDISM; and gonadal failure. In both types organ-specific ANTIBODIES against a variety of ENDOCRINE GLANDS have been detected. The type II syndrome differs from type I in that it is associated with HLA-A1 and B8 haplotypes, onset is usually in adulthood, and candidiasis is not present.

Polyenes
|
D011090 |
[Compounds with four adjacent carbons joined by double bonds.
, Hydrocarbons with more than one double bond. They are a reduced form of POLYYNES.

|
Polyesters
|
D011091 |
[Polymers of organic acids and alcohols, with ester linkages--usually polyethylene terephthalate; can be cured into hard plastic, films or tapes, or fibers which can be woven into fabrics, meshes or velours.
] |
|
Polyethylene
|
D020959 |
[A vinyl polymer made from ethylene. It can be branched or linear. Branched or low-density polyethylene is tough and pliable but not to the same degree as linear polyethylene. Linear or high-density polyethylene has a greater hardness and tensile strength. Polyethylene is used in a variety of products, including implants and prostheses.

|
Polyethylene Glycols
|
D011092 |
[Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.

|
Polyethylene Terephthalates
|
D011093 |
[Polyester polymers formed from terephthalic acid or its esters and ethylene glycol. They can be formed into tapes, films or pulled into fibers that are pressed into meshes or woven into fabrics.

Polyethyleneimine
|
D011094 |
[Strongly cationic polymer that binds to certain proteins; used as a marker in immunology, to precipitate and purify enzymes and lipids. Synonyms: aziridine polymer; Epamine; Epomine; ethylenimine polymer; Montrek; PEI; Polymin(e).

Polyethylenes
|
D011095 |
[Synthetic thermoplastics that are tough, flexible, inert, and resistant to chemicals and electrical current. They are often used as biocompatible materials for prostheses and implants.
