Amnesia, Anterograde
|
D020324 |
[Loss of the ability to form new memories beyond a certain point in time. This condition may be organic or psychogenic in origin. Organically induced anterograde amnesia may follow CRANIOCEREBRAL TRAUMA; SEIZURES; ANOXIA; and other conditions which adversely affect neural structures associated with memory formation (e.g., the HIPPOCAMPUS; FORNIX (BRAIN); MAMMILLARY BODIES; and ANTERIOR THALAMIC NUCLEI). (From Memory 1997 Jan-Mar;5(1-2):49-71)

Amnesia, Retrograde
|
D000648 |
[Loss of the ability to recall information that had been previously encoded in memory prior to a specified or approximate point in time. This process may be organic or psychogenic in origin. Organic forms may be associated with CRANIOCEREBRAL TRAUMA; CEREBROVASCULAR ACCIDENTS; SEIZURES; DEMENTIA; and a wide variety of other conditions that impair cerebral function. (From Adams et al., Principles of Neurology, 6th ed, pp426-9)

Amnesia, Transient Global
|
D020236 |
[A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours. During the period of amnesia, immediate and recent memory abilities are impaired, but the level of consciousness and ability to perform other intellectual tasks are preserved. The condition is related to bilateral dysfunction of the medial portions of each TEMPORAL LOBE. Complete recovery normally occurs, and recurrences are unusual. (From Adams et al., Principles of Neurology, 6th ed, pp429-30)

Amniocentesis
|
D000649 |
[Percutaneous transabdominal puncture of the uterus during pregnancy to obtain amniotic fluid. It is commonly used for fetal karyotype determination in order to diagnose abnormal fetal conditions.
] |
|
Amnion
|
D000650 |
[The innermost membranous sac that surrounds and protects the developing embryo which is bathed in the AMNIOTIC FLUID. Amnion cells are secretory EPITHELIAL CELLS and contribute to the amniotic fluid.

|
Amniotic Band Syndrome
|
D000652 |
[A disorder present in the newborn infant in which constriction rings or bands, causing soft tissue depressions, encircle digits, extremities, or limbs and sometimes the neck, thorax, or abdomen. They may be associated with intrauterine amputations.

|
Amniotic Fluid
|
D000653 |
[An evaluation of the amount of amniotic fluid.
, A clear, yellowish liquid that envelopes the FETUS inside the sac of AMNION. In the first trimester, it is likely a transudate of maternal or fetal plasma. In the second trimester, amniotic fluid derives primarily from fetal lung and kidney. Cells or substances in this fluid can be removed for prenatal diagnostic tests (AMNIOCENTESIS).

|
Amniotomy
|
D000074885 |
[A method of inducing labor by deliberate rupture of the AMNION to cause the release of amniotic fluid.

|
Amobarbital
|
D000654 |
[A barbiturate with hypnotic and sedative properties (but not antianxiety). Adverse effects are mainly a consequence of dose-related CNS depression and the risk of dependence with continued use is high. (From Martindale, The Extra Pharmacopoeia, 30th ed, p565)

Amodiaquine
|
D000655 |
[A 4-aminoquinoline compound with anti-inflammatory properties.

|
Amoeba
|
D000656 |
[A genus of ameboid protozoa. Characteristics include a vesicular nucleus and the formation of several PSEUDOPODIA, one of which is dominant at a given time. Reproduction occurs asexually by binary fission.

|
Amoebida
|
D016841 |
[An order of ameboid protozoa that is commonly uninucleate and possess mitochondria. Most organisms are nonpathogenic.

|
Amoebozoa
|
D056894 |
[A supergroup (some say phylum) of ameboid EUKARYOTES, comprising ARCHAMOEBAE; LOBOSEA; and MYCETOZOA.

|
Amomum
|
D035801 |
[A plant genus of the family ZINGIBERACEAE. Members contain aculeatin D, beta-sitosterol, and STIGMASTEROL. Some members have been reclassified to ELETTARIA and other ZINGIBERACEAE.

Amorphophallus
|
D031056 |
[A plant genus of the family ARACEAE. Members contain konjac glucomannan (MANNANS) and SEROTONIN.

|
Amoxapine
|
D000657 |
[The N-demethylated derivative of the antipsychotic agent LOXAPINE that works by blocking the reuptake of norepinephrine, serotonin, or both; it also blocks dopamine receptors. Amoxapine is used for the treatment of depression.

|
Amoxicillin
|
D000658 |
[A broad-spectrum semisynthetic antibiotic similar to AMPICILLIN except that its resistance to gastric acid permits higher serum levels with oral administration.

Amoxicillin-Potassium Clavulanate Combination
|
D019980 |

|
Amphetamine
|
D000661 |
[A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
