nucle-, nucleo-, nuc- +

(Latin: nut, kernel of a nut; stone of a fruit; central part of a cell)

The study of the biological applications of radioactive and rare stable isotopes.
infectious mononucleosis (noun); pfeiffersches drüsenfieber (German term)
1. An acute infectious disease caused by the Epstein-Barr virus, producing fever, swelling of the lymph nodes, sore throat, and increased lymphocytes in the blood.
2. A specific viral infection with the Epstein-Barr virus in which there is an increase of white blood cells that are mononuclear (with a single nucleus).

"Mono" and "kissing disease" are popular terms for this very common illness caused by the Epstein-Barr virus (EBV); however, by the time most people reach adulthood, an antibody against EBV can be detected in their blood meaning they have been infected with EBV.

The illness is less severe in young children and the infection can be spread by saliva. Symptoms include fever, fatigue, sore throat, and swollen lymph glands.

"Mono" can cause liver inflammation (hepatitis) and spleen enlargement. Vigorous contact sports should be avoided to prevent spleen rupture.

Since mono is caused by a virus and not bacteria, antibiotics are of no benefit; therefore, treatment is directed at relieving the symptoms, which may persist for one to two months.

1. Located or occurring between nuclei.
2. Pertaining to or affecting structures between nuclei, as internuclear ophthalmoplegia.
3. Between the nuclear layers of the retina.
1. Existing or occurring within the nucleus of an atom or within the nucleus of a cell.
2. Within the nucleus of a cell; as, the intranuclear network of fibrils, seen in the first stages of karyokinesis (series of active changes that take place in the nucleus of a living cell in the process of division).
macronucleus (s), macronuclei (pl)
The larger of two nuclei in most ciliate protozoans, involved in nonreproductive functions; such as, feeding and metabolism.
The larger of two nuclei present in ciliate protozoans, which controls the nonreproductive functions of the cell.
micronucleus (s), micronuclei (pl)
The smaller of the two nuclei in the cells of ciliate protozoans. It contains genetic material and is involved in sexual reproduction.
1. A description of a cell that has a single nucleus.
2. An organic compound with a molecular structure containing only one ring of atoms.
mononucleosis (s), mononucleoses (pl) (noun forms)
1. A significant rise in the number of atypical lymphocytes in the blood.
2. A viral infection marked by extreme fatigue, high fever, and swollen lymph nodes, caused by an unusually high number of monocytes.
3. An acute disease characterized by fever and swollen lymph nodes and an abnormal increase of mononuclear leucocytes or monocytes in the bloodstream; not highly contagious; however, some believe it can be transmitted by kissing.
1. Relating to or constituting the nucleus of an atom.
2. A reference to or constituting the nucleus of a cell.
3. Constituting or like a nucleus: "Annexation of the suburban fringe by the nuclear metropolis."
4. Deriving destructive energy from the release of atomic energy.
1. To bring together into a nucleus.
2. To act as a nucleus for.
3. To provide a nucleus for or to form a nucleus.
1. The process by which ice crystals and rain drops form in clouds around a solid core.
2. The formation of mineral crystals from a melt, often around a core of solid material.
3. The formation of cell nuclei.
Formed like a nucleus or kernel.
1. Any of the substances present in the nucleus of a cell, consisting chiefly of proteins, phosphoric acids, and nucleic acids.
2. A decomposition product of nucleoprotein intermediate between native nucleoprotein and nucleic acid.

It is a colorless, amorphous compound, soluble in dilute alkalis, but insoluble in dilute acids. The nucleins consist of nucleic acid and bases which vary in the different nucleins.

1. The basic viral structure consisting of a core of nucleic acid surrounded by a protein coat.
2. The genome plus the protein coat of a virus.

The nucleic acid (RNA or DNA) of the virus is its genome. The protein coat is its capsid (which is protein coat of a virus).
