Hemerythrin
|
D006422 |
[A non-heme iron protein consisting of eight apparently identical subunits each containing 2 iron atoms. It binds one molecule of oxygen per pair of iron atoms and functions as a respiratory protein.

|
Hemianopsia
|
D006423 |
[Partial or complete loss of vision in one half of the visual field(s) of one or both eyes. Subtypes include altitudinal hemianopsia, characterized by a visual defect above or below the horizontal meridian of the visual field. Homonymous hemianopsia refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field. Binasal hemianopsia consists of loss of vision in the nasal hemifields of both eyes. Bitemporal hemianopsia is the bilateral loss of vision in the temporal fields. Quadrantanopsia refers to loss of vision in one quarter of the visual field in one or both eyes.

Hemiarthroplasty
|
D062785 |
[A partial joint replacement in which only one surface of the joint is replaced with a PROSTHESIS.

|
Hemibody Irradiation
|
D017619 |
[Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (UHBI) or lower hemibody irradiation (LHBI). Less common is mid-body irradiation (MBI). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with WHOLE-BODY IRRADIATION. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (P. Rubin et al. Cancer, Vol 55, p2210, 1985)

Hemic and Immune Systems
|
D006424 |
[Organs involved in the production of BLOOD, including the cellular and the molecular components essential in providing defense against foreign organisms or substances.

|
Hemic and Lymphatic Diseases
|
D006425 |
[Hematologic diseases and diseases of the lymphatic system collectively. Hemic diseases include disorders involving the formed elements (e.g., ERYTHROCYTE AGGREGATION, INTRAVASCULAR) and chemical components (e.g., BLOOD PROTEIN DISORDERS); lymphatic diseases include disorders relating to lymph, lymph nodes, and lymphocytes.

Hemicentrotus
|
D047330 |
[The only and type species of Hemicentrotus.
, A genus of SEA URCHINS in the family Strongylocentrotidae with a hemicyclic apical disk and short spines.
] |
|
Hemicholinium 3
|
D006426 |
[A potent inhibitor of the high affinity uptake system for CHOLINE. It has less effect on the low affinity uptake system. Since choline is one of the components of ACETYLCHOLINE, treatment with hemicholinium can deplete acetylcholine from cholinergic terminals. Hemicholinium 3 is commonly used as a research tool in animal and in vitro experiments.

|
Hemidesmosomes
|
D022002 |
[An anchoring junction of the cell to a non-cellular substrate, similar in morphology to halves of DESMOSOMES. They are composed of specialized areas of the plasma membrane where INTERMEDIATE FILAMENTS bind on the cytoplasmic face to the transmembrane linkers, INTEGRINS, via intracellular attachment proteins, while the extracellular domain of the integrins binds to EXTRACELLULAR MATRIX PROTEINS.

Hemidesmus
|
D031102 |
[A plant genus of the family Apocynaceae. It is a source of PREGNANES and is sometimes an adulterant of commercial sarsaparilla (SMILAX).

|
Hemifacial Spasm
|
D019569 |
[Recurrent clonic contraction of facial muscles, restricted to one side. It may occur as a manifestation of compressive lesions involving the seventh cranial nerve (FACIAL NERVE DISEASES), during recovery from BELL PALSY, or in association with other disorders. (From Adams et al., Principles of Neurology, 6th ed, p1378)

|
Hemiplegia
|
D006429 |
[Severe or complete loss of motor function on one side of the body. This condition is usually caused by BRAIN DISEASES that are localized to the cerebral hemisphere opposite to the side of weakness. Less frequently, BRAIN STEM lesions; cervical SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; and other conditions may manifest as hemiplegia. The term hemiparesis (see PARESIS) refers to mild to moderate weakness involving one side of the body.

Hemiptera

D006430 |
[A large order of insects characterized by having the mouth parts adapted to piercing or sucking. It is comprised of four suborders: HETEROPTERA, Auchenorrhyncha, Sternorrhyncha, and Coleorrhyncha.
