Neurotensin
|
D009496 |
[A biologically active tridecapeptide isolated from the hypothalamus. It has been shown to induce hypotension in the rat, to stimulate contraction of guinea pig ileum and rat uterus, and to cause relaxation of rat duodenum. There is also evidence that it acts as both a peripheral and a central nervous system neurotransmitter.

Neurothekeoma
|
D018321 |
[A benign myxoma of cutaneous nerve sheath origin. Theke is from the Greek theke, sheath. (From Stedman, 25th ed)

|
Neurotic Disorders
|
D009497 |
[Disorders in which the symptoms are distressing to the individual and recognized by him or her as being unacceptable. Social relationships may be greatly affected but usually remain within acceptable limits. The disturbance is relatively enduring or recurrent without treatment.

|
Neuroticism
|
D000075384 |
[Personality trait related to tendency to respond to threat, frustration or a loss with negative emotions (e.g., ANGER; ANXIETY; FRUSTRATION; embarrassment and sadness).

Neurotology
|
D063165 |
[A subspecialty of otolaryngology dealing with the parts of the nervous system related to the ear.

Neurotoxicity Syndromes
|
D020258 |
[Neurologic disorders caused by exposure to toxic substances through ingestion, injection, cutaneous application, or other method. This includes conditions caused by biologic, chemical, and pharmaceutical agents.

|
Neurotoxins
|
D009498 |
[Toxic substances from microorganisms, plants or animals that interfere with the functions of the nervous system. Most venoms contain neurotoxic substances. Myotoxins are included in this concept.

|
Neurotransmitter Agents
|
D018377 |
[Endogenous signaling molecules secreted by neurons that alter the behavior of neurons or effector cells. Neurotransmitter is used here in its most general sense, including not only messengers that act directly to regulate ion channels, but also those that act through second messenger systems, and those that act at a distance from their site of release. Included are neuromodulators, neuroregulators, neuromediators, neurohormones, and neurohumors, whether or not acting at synapses.
, Substances secreted by neurons into the blood, CNS, or intercellular space.
, Substances used for their pharmacological actions on any aspect of neurotransmitter systems. Neurotransmitter agents include agonists, antagonists, degradation inhibitors, uptake inhibitors, depleters, precursors, and modulators of receptor function.

Neurotransmitter Transport Proteins
|
D050479 |
[Membrane transport proteins found predominately in NEURONS and neuroendocrine cells that facilitate neurotransmitter transport. They include two distinct families of proteins that transport NEUROTRANSMITTERS across the PLASMA MEMBRANE and that transport NEUROTRANSMITTERS into SECRETORY VESICLES.
] |
|
Neurotransmitter Uptake Inhibitors
|
D014179 |
[Drugs that inhibit the transport of neurotransmitters into axon terminals or into storage vesicles within terminals. For many transmitters, uptake determines the time course of transmitter action so inhibiting uptake prolongs the activity of the transmitter. Blocking uptake may also deplete available transmitter stores. Many clinically important drugs are uptake inhibitors although the indirect reactions of the brain rather than the acute block of uptake itself is often responsible for the therapeutic effects.

Neurotrophin 3
|
D020933 |
[A neurotrophic factor involved in regulating the survival of visceral and proprioceptive sensory neurons. It is closely homologous to nerve growth factor beta and BRAIN-DERIVED NEUROTROPHIC FACTOR.
] |
|
Neurovascular Coupling
|
D000069336 |
[Mechanism by which changes in neural activity are tightly associated with regional cortical HEMODYNAMICS and metabolism changes. The association is often inferred from NEUROIMAGING signals (e.g., fMRI; or NIR SPECTROSCOPY).
] |
|
Neurturin
|
D051101 |
[A glial cell line-derived neurotrophic factor ligand that is specific for the GFRA2 RECEPTOR. Neurturin is essential for the development of specific postganglionic parasympathetic NEURONS.
] |
|
Neurulation
|
D054261 |
[An early embryonic developmental process of CHORDATES that is characterized by morphogenic movements of ECTODERM resulting in the formation of the NEURAL PLATE; the NEURAL CREST; and the NEURAL TUBE. Improper closure of the NEURAL GROOVE results in congenital NEURAL TUBE DEFECTS.

|
Neutral Ceramidase
|
D055576 |
[A ceramidase subtype that is active at neutral pH. It is found at high levels within the SMALL INTESTINE and in the BRAIN.
] |
|
Neutral Glycosphingolipids
|
D020383 |
[A subclass of GLYCOSPHINGOLIPIDS containing one or more sugars within their head group connected directly to a ceramide moiety. They consist of monoglycosyl-, and oligoglycosylsphingoids and monoglycosyl- and oligoglycosylceramides.
] |
|
Neutral Red
|
D009499 |
[A vital dye used as an indicator and biological stain. Various adverse effects have been observed in biological systems.
] |
|
Neutralization Tests
|
D009500 |
[The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).

Neutron Activation Analysis
|
D009501 |
[Activation analysis in which the specimen is bombarded with neutrons. Identification is made by measuring the resulting radioisotopes. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

|
Neutron Capture Therapy
|
D017247 |
[A technique for the treatment of neoplasms in which an isotope is introduced into target cells followed by irradiation with thermal neutrons.
