Hypoxia
|
D000860 |
[Sub-optimal OXYGEN levels in the ambient air of living organisms.
, Relatively complete absence of oxygen in one or more tissues.

|
Hypoxia, Brain
|
D002534 |
[A reduction in brain oxygen supply due to ANOXEMIA (a reduced amount of oxygen being carried in the blood by HEMOGLOBIN), or to a restriction of the blood supply to the brain, or both. Severe hypoxia is referred to as anoxia, and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives.

Hypoxia-Inducible Factor 1
|
D051793 |
[A basic helix-loop-helix transcription factor that plays a role in APOPTOSIS. It is composed of two subunits: ARYL HYDROCARBON RECEPTOR NUCLEAR TRANSLOCATOR and HYPOXIA-INDUCIBLE FACTOR 1, ALPHA SUBUNIT.

|
Hypoxia-Inducible Factor 1, alpha Subunit
|
D051795 |
[Hypoxia-inducible factor 1, alpha subunit is a basic helix-loop-helix transcription factor that is regulated by OXYGEN availability and is targeted for degradation by VHL TUMOR SUPPRESSOR PROTEIN.

|
Hypoxia-Inducible Factor-Proline Dioxygenases
|
D064799 |
[Dioxygenase enzymes that specifically hydroxylate a PROLINE residue on the HYPOXIA-INDUCIBLE FACTOR 1, ALPHA SUBUNIT. They are OXYGEN-dependent enzymes that play an important role in mediating cellular adaptive responses to HYPOXIA.

|
Hypoxia-Ischemia, Brain
|
D020925 |
[A disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ISCHEMIA) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions.

Hypromellose Derivatives
|
D065347 |
[Polymeric compounds that contain repeating units of hydroxypropyl methylcellulose. The properties of hypromellose polymers can vary greatly and are defined by their molecular weight, the percentage of hydroxyl groups, the percentage of hydroxypropyl groups, and viscosity measurements. They are found a broad variety of commercial products such as FOOD ADDITIVES; EXCIPIENTS; and LUBRICANTS.

Hyssopus Plant
|
D000068819 |
[A genus in the mint family (Lamiaceae). Members contain thujone and PHENOL. Distinguished from AGASTACHE (giant hyssop) and BACOPA (water hyssop). Also distinguished from the genus of WASPS with the same genus name Hyssopus.

Hysteria
|
D007046 |
[Historical term for a chronic, but fluctuating, disorder beginning in early life and characterized by recurrent and multiple somatic complaints not apparently due to physical illness. This diagnosis is not used in contemporary practice.

I Blood-Group System
|
D007048 |
[A blood group related both to the ABO and P systems that includes several different antigens found in most people on erythrocytes, in milk, and in saliva. The antibodies react only at low temperatures.
