Hemispherectomy
|
D038421 |
[Removal of the entire cortex, sparing the BASAL GANGLIA.
, A neurosurgical procedure that removes or disconnects the epileptogenic CEREBRAL CORTEX of a hemisphere. Hemispherectomy is usually performed for patients with intractable unilateral EPILEPSY due to malformations of cortical development or brain lesions. Depending on the epileptogenic area in the hemisphere, cortical removal can be total or partial.
, The procedure consists of removing frontal and temporal lobes, and complete disconnection of the remaining cortex and CORPUS CALLOSUM.

Hemiterpenes
|
D045782 |
[Compounds that include a single 2-methyl-1,3-butadiene (also known as isoprene) within their structure.

|
Hemizygote
|
D057898 |
[An individual having only one allele at a given locus because of the loss of the other allele through a mutation (e.g., CHROMOSOME DELETION).

|
Hemlock
|
D018652 |
[Any of several poisonous plants, commonly called poison hemlock, of the CICUTA or CONIUM genus. The hemlock tree (TSUGA) is completely unrelated being a coniferous tree of the pine family.

Hemobilia
|
D006431 |
[Hemorrhage in or through the BILIARY TRACT due to trauma, inflammation, CHOLELITHIASIS, vascular disease, or neoplasms.

|
Hemochromatosis
|
D006432 |
[A disorder of iron metabolism characterized by a triad of HEMOSIDEROSIS; LIVER CIRRHOSIS; and DIABETES MELLITUS. It is caused by massive iron deposits in parenchymal cells that may develop after a prolonged increase of iron absorption. (Jablonski's Dictionary of Syndromes & Eponymic Diseases, 2d ed)

Hemochromatosis Protein
|
D000071020 |
[A membrane protein and MHC class I antigen. It contains an IMMUNOGLOBULIN C1-SET DOMAIN and interacts with BETA 2-MICROGLOBULIN. It may also regulate the interaction of TRANSFERRIN with the TRANSFERRIN RECEPTOR. Mutations in the HFE gene are associated with cases of FAMILIAL HEMOCHROMATOSIS.

|
Hemocyanins
|
D006433 |
[Metalloproteins that function as oxygen transport proteins in the HEMOLYMPH of MOLLUSKS and ARTHROPODS. They are characterized by two copper atoms, coordinated with HISTIDINE residues, that reversibly bind a single oxygen molecule; they do not contain HEME groups.

Hemocytes
|
D006434 |
[Any blood or formed element especially in invertebrates.
] |
|
Hemodiafiltration
|
D017583 |
[The combination of hemodialysis and hemofiltration either simultaneously or sequentially. Convective transport (hemofiltration) may be better for removal of larger molecular weight substances and diffusive transport (hemodialysis) for smaller molecular weight solutes.
] |
|
Hemodialysis Solutions
|
D015312 |
[Solutions prepared for hemodialysis. The composition of the pre-dialysis solution may be varied in order to determine the effect of solvated metabolites on anoxia, malnutrition, acid-base balance, etc. Of principal interest are the effect of the choice of buffers (e.g., acetate or carbonate), the addition of cations (Na+, K+, Ca2+), and addition of carbohydrates (glucose).

Hemodialysis Units, Hospital
|
D006436 |
[Hospital units in which care is provided the hemodialysis patient. This includes hemodialysis centers in hospitals.

|
Hemodialysis, Home
|
D006437 |
[Long-term maintenance hemodialysis in the home.
] |
|
Hemodilution
|
D006438 |
[Reduction of blood viscosity usually by the addition of cell free solutions. Used clinically (1) in states of impaired microcirculation, (2) for replacement of intraoperative blood loss without homologous blood transfusion, and (3) in cardiopulmonary bypass and hypothermia.

Hemodynamic Monitoring
|
D000074743 |
[Continuous measurement of the movement and forces of blood in the CARDIOVASCULAR SYSTEM.
] |
|
Hemodynamics
|
D006439 |
[The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.
] |
|
Hemofiltration
|
D006440 |
[Extracorporeal ULTRAFILTRATION technique without HEMODIALYSIS for treatment of fluid overload and electrolyte disturbances affecting renal, cardiac, or pulmonary function.
] |
|
Hemoglobin A
|
D006441 |
[Normal adult human hemoglobin. The globin moiety consists of two alpha and two beta chains.
] |
|
Hemoglobin A2
|
D006443 |
[An adult hemoglobin component normally present in hemolysates from human erythrocytes in concentrations of about 3%. The hemoglobin is composed of two alpha chains and two delta chains. The percentage of HbA2 varies in some hematologic disorders, but is about double in beta-thalassemia.
] |
|
Hemoglobin C
|
D006444 |
[A commonly occurring abnormal hemoglobin in which lysine replaces a glutamic acid residue at the sixth position of the beta chains. It results in reduced plasticity of erythrocytes.
