Oxytocics
|
D010120 |
[Drugs that stimulate contraction of the myometrium. They are used to induce LABOR, OBSTETRIC at term, to prevent or control postpartum or postabortion hemorrhage, and to assess fetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (ABORTIFACIENTS). Oxytocics used clinically include the neurohypophyseal hormone OXYTOCIN and certain prostaglandins and ergot alkaloids. (From AMA Drug Evaluations, 1994, p1157)

Oxytocin
|
D010121 |
[A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION.

Ozone
|
D010126 |
[Ozone in the lower troposphere, just above the surface of the Earth.
, The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).
, Ozone in the troposphere. It is considered a secondary air pollutant because it is produced by the reaction of solar ULTRAVIOLET RAYS with other AIR POLLUTANTS and because of its harmful effects on the respiratory system and the environment.

|
Ozone Depletion
|
D062966 |
[A shift in the balance between production and destruction of STRATOSPHERIC OZONE that results in a decline of the amount of OZONE in the lower stratosphere.
, A large area over a region of the Earth in the OZONE LAYER where OZONE destruction has overtaken ozone production.

P Blood-Group System
|
D010127 |
[A blood group related to the ABO, Lewis and I systems. At least five different erythrocyte antigens are possible, some very rare, others almost universal. Multiple alleles are involved in this blood group.

P-Selectin
|
D019007 |
[Cell adhesion molecule and CD antigen that mediates the adhesion of neutrophils and monocytes to activated platelets and endothelial cells.

|
P-type ATPases
|
D000073779 |
[A highly conserved family of ATPases that facilitate the transport of lipids and cations across the plasma membrane. Structurally, they are elongated ALPHA-HELICES constituting five functionally distinct domains: three cytoplasmic domains A, N, and P which contain the catalytic sites, and two transmembrane domains. The N domain phosphorylates the P-domain at an invariant ASPARTATE residue, which, in turn, is dephosphorylated by the A domain. The phosphorylation and dephosphorylation cycles drive conformational changes in the protein between two states (E1 and E2), which allow the substrate to access the other side of the membrane.

|
PAX3 Transcription Factor
|
D000072041 |
[A paired box transcription factor that functions in CELL PROLIFERATION; CELL MIGRATION; and APOPTOSIS. It also is involved in MYOGENESIS and neural development. Mutations in the PAX3 gene are associated with WAARDENBURG SYNDROME TYPE 1.

|
PAX5 Transcription Factor
|
D051757 |
[Pax5A transcription factor is the major isoform of B-cell-specific activator protein.
, A paired box transcription factor that is essential for CELL DIFFERENTIATION of B-LYMPHOCYTES. It functions both as a transcriptional activator and repressor to mediate B-cell commitment.

|
PAX6 Transcription Factor
|
D000071841 |
[A paired box transcription factor that has important functions in the development of the eye, nose, central nervous system and pancreas. Mutations in the PAX6 gene are associated with ocular disorders such as ANIRIDIA.
