Eukaryote
|
|
EukaryoteAn organism that consists of one or more cells each of which has a nucleus and other well-developed intracellular compartments. Eukaryotes include all organisms except bacteria, viruses, and certain (blue-green) algae which, by contrast, are prokaryotes.
RELATED TERMS--------------------------------------
Organism
A living thing, such as an animal, a plant, a bacterium, or a fungus.
Nucleus
Plural: nuclei. The compartment of a cell that contains the chromosomes.
Intracellular
Within cells.
Bacteria
Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life).
Contrast
"Short for ""contrast media."" Contrast media are X-ray dyes used to provide contrast, for example, between blood vessels and other tissue."
SIMILAR TERMS--------------------------------------
Eukaryotic
The living world is divided into two classes of organism. Eukaryotic and, much simpler, prokaryotic organisms such as bacteria. Generally eukaryotes are diploid and their cells have internal organelles, such as nuclei. Prokaryotes are haploid with much simpler cells.
PREVIOUS AND NEXT TERMS--------------------------------------
Ethylene glycol poisoning
Poisoning from ethylene glycol (a clear, colorless, odorless liquid with a sweet taste) that can produce dramatic and dangerous toxicity.
Ethylene oxide
A chemical widely used in the health care industry to sterilize medical devices and also used to make other chemicals.
ETM1
A gene for essential tremor, uncontrollable shaking of the hands and head and sometimes other parts of the body. The ETM1 gene (also called FET1) was mapped in 1997 to chromosome region 3q13 in a study of Icelandic families. EMT1 is responsible for a fine rapid hand tremor; late tremor of arms, tongue, head, legs and trunk; dysarthria; mild rigidity; and stiff gait. The onset of symptoms is about 50 years, later in women than men. The condition is progressive. The intellect is spared.
ETM2
A gene for essential tremor, uncontrollable shaking of the hands and head and sometimes other parts of the body. The ETM2 gene was mapped to chromosome region 2p25-p22. ETM2 is responsible for essential tremor; postural tremor of arms; and variable tremor of head, legs, trunk, voice, jaw, and facial muscles. The tremor is aggravated by emotions, hunger, fatigue, and temperature extremes.
ETS
Environmental tobacco smoke. Smoke generated from the sidestream (the burning end) of a cigarette, pipe or cigar and the exhaled mainstream smoke (the smoke that is puffed out by smokers) of cigarettes, pipes, and cigars.
Eukaryote
Euphenics
Literally meaning "normal appearing," euphenics aims to improve the outcome of a genetic disease by altering the environment.
Euploid
The normal number of chromosomes for a species. In humans, the euploid number of chromosomes is 46 with the notable exception of the unfertilized egg and sperm in which it is 23.
EUS
Endoscopic ultrasound.
Euthanasia
The most commonly understood meaning of euthanasia today is more than the old dictionary definition of dying well -- a good and easy death. It refers, for example, to the situation when a doctor induces the death with a lethal injection, of a patient who is suffering unrelievably and has persistently requested the doctor to do so. Suicide, whether irrational or rational, for unrelated reasons is not euthanasia. Nor is the forced killing of another person.
Euthanasia, active
The active acceleration of a "good" death by use of drugs etc, whether by oneself or with the aid of a doctor. Today the most commonly understood meaning of euthanasia is more than this old dictionary definition of dying well a good and easy death. Euthanasia refers, for example, to the situation when a doctor induces the death with a lethal injection, of a patient who is suffering without relief and has persistently requested the doctor to do so.Suicide, whether irrational or rational, for unrelated reasons is not euthanasia. Nor is the forced killing of another person.
