High Pressure Neurological Syndrome
|
D006610 |
[A syndrome related to increased atmospheric pressure and characterized by tremors, nausea, dizziness, decreased motor and mental performance, and SEIZURES. This condition may occur in those who dive deeply (c. 1000 ft) usually while breathing a mixture of oxygen and helium. The condition is associated with a neuroexcitatory effect of helium.

High Reliability Organizations
|
D000085264 |
[Organizations operating complex, high-hazard domains for extended periods without serious accidents or catastrophic failures. The concept of high reliability extends beyond standardization. High reliability organizations cultivate resilience by relentlessly prioritizing safety over other performance pressures. (from https://psnet.ahrq.gov/primer/high-reliability accessed 3/25/2020)

High Vocal Center
|
D053400 |
[Nucleus in the NEOSTRIATUM of bird brains that sends signals for song production and receives auditory input. In some adult SONGBIRDS, research has shown that the size of this nucleus changes seasonally and that it exhibits neurogenesis.

High-Density Lipoproteins, Pre-beta
|
D053442 |
[A highly dense subclass of the high-density lipoproteins, with particle sizes below 7 nm. They are also known as nascent HDL, composed of a few APOLIPOPROTEIN A-I molecules which are complexed with PHOSPHOLIPIDS. The lipid-poor pre-beta-HDL particles serve as progenitors of HDL3 and then HDL2 after absorption of free cholesterol from cell membranes, cholesterol esterification, and acquisition of apolipoproteins A-II, Cs, and E. Pre-beta-HDL initiate the reverse cholesterol transport process from cells to liver.

High-Energy Shock Waves
|
D019220 |
[High-amplitude compression waves, across which density, pressure, and particle velocity change drastically. The mechanical force from these shock waves can be used for mechanically disrupting tissues and deposits.

|
High-Frequency Jet Ventilation
|
D006611 |
[Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances.
] |
|
High-Frequency Ventilation
|
D006612 |
[Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).

High-Intensity Focused Ultrasound Ablation
|
D057086 |
[The use of focused, high-frequency sound waves to destroy tissue. It is sometimes used in conjunction with but is distinct from INTERVENTIONAL ULTRASONOGRAPHY.

|
High-Intensity Interval Training
|
D000072696 |
[A cardiovascular exercise strategy with alternating short periods of intense anaerobic exercise with less-intense recovery periods.

High-Temperature Requirement A Serine Peptidase 1
|
D000074289 |
[A secreted serine protease that contains a Kazal domain-like region and a C-terminal PDZ domain. It has a broad range of targets that include EXTRACELLULAR MATRIX PROTEINS; PROTEOGLYCANS; and INSULIN-LIKE GROWTH FACTOR BINDING PROTEINS. Mutations in the HTRA1 gene are associated with AGE-RELATED MACULAR DEGENERATION 7 and Cerebral Autosomal Recessive Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CARASIL).

|
High-Temperature Requirement A Serine Peptidase 2
|
D000074923 |
[A serine peptidase that contains a C-terminal PDZ domain. It localizes to the mitochondrial membrane and intermembrane space, translocating to the cytoplasm following APOPTOSIS stimuli, such as UV irradiation; it promotes cell death by binding to and inhibiting INHIBITOR OF APOPTOSIS PROTEINS, resulting in an increase in activity of CASPASES. Mutations in the HTRA2 gene are associated with Type 13 PARKINSON DISEASE.

High-Throughput Nucleotide Sequencing
|
D059014 |
[Techniques of nucleotide sequence analysis that increase the scale of operations enabling an increase in the depth of coverage (number of copies) to which each polynucleotide is sequenced.
, Techniques of nucleotide sequence analysis that increase the range, complexity, sensitivity, and accuracy of results by greatly increasing the scale of operations and thus the number of nucleotides, and the number of copies of each nucleotide sequenced. The sequencing may be done by analysis of the synthesis or ligation products, hybridization to preexisting sequences, etc.

|
High-Throughput Screening Assays
|
D057166 |
[Rapid methods of measuring the effects of an agent in a biological or chemical assay. The assay usually involves some form of automation or a way to conduct multiple assays at the same time using sample arrays.

|
Higher Nervous Activity
|
D006613 |
[A term used in Eastern European research literature on brain and behavior physiology for cortical functions. It refers to the highest level of integrative function of the brain, centered in the CEREBRAL CORTEX, regulating language, thought, and behavior via sensory, motor, and cognitive processes.

Hindlimb
|
D006614 |
[Either of two extremities of four-footed non-primate land animals. It usually consists of a FEMUR; TIBIA; and FIBULA; tarsals; METATARSALS; and TOES. (From Storer et al., General Zoology, 6th ed, p73)

|
Hindlimb Suspension
|
D019417 |
[Technique for limiting use, activity, or movement by immobilizing or restraining animal by suspending from hindlimbs or tails. This immobilization is used to simulate some effects of reduced gravity and study weightlessness physiology.
, This refers to skeletal muscle usually related to the hindlimb.

Hinduism
|
D018596 |
[A complex body of social, cultural, and religious beliefs and practices evolved in and largely confined to the Indian subcontinent and marked by a caste system, an outlook tending to view all forms and theories as aspects of one eternal being and truth, and the practice of the way of works, the way of knowledge, or the way of devotion as a means of release from the round of rebirths. (From Webster, 3d ed)

Hinge Exons
|
D052058 |
[Immunoglobulin heavy chain gene exons coding for the hinge region of the heavy chains between the first constant region (on the FAB FRAGMENTS) and the second constant region (on the FC FRAGMENTS).

Hip
|
D006615 |
[The projecting part on each side of the body, formed by the side of the pelvis and the top portion of the femur.

|
Hip Contracture
|
D006616 |
[Permanent fixation of the hip in primary positions, with limited passive or active motion at the hip joint. Locomotion is difficult and pain is sometimes present when the hip is in motion. It may be caused by trauma, infection, or poliomyelitis. (From Current Medical Information & Technology, 5th ed)
