oligodendroglia |
A class of neuroglial (macroglial) cells in the central nervous system. Oligodendroglia may be called interfascicular, perivascular, or perineuronal satellite cells according to their location. The most important recognised function of these cells is the formation of the insulating myelin sheaths of axons in the central nervous system. (12 Dec 1998) |

oligodendroglioma |
<oncology, tumour> May be subdivided into primary brain tumours and the more common, secondary brain tumours. Primary brain tumours (for example astrocytoma, craniopharyngioma, glioma, ependymoma, neuroglioma, oligodendroglioma, glioblastoma multiforme, meningioma, medulloblastoma) arise from the uncontrolled proliferation of cells within the brain. Secondary brain tumours occur from the spread of cancer into the brain from a distant cancerous organ (metastasis). Common symptoms of a brain tumour include headache, nausea, vomiting, seizures, change in mentation, neurologic symptoms and loss of memory. (27 Sep 1997) |

A group of deoxyribonucleotides (up to 12) in which the phosphate residues of each deoxyribonucleotide act as bridges in forming diester linkages between the deoxyribose moieties. (12 Dec 1998) |

Oligohymenophorea
|
The Oligohymenophorea are a large class of ciliate protozoa. There is typically a ventral groove containing the mouth and distinct oral cilia, separate from those of the body. These include a paroral membrane to the right of the mouth and membranelles, usually three in number, to its left. The cytopharynx is inconspicuous and never forms the complex cyrtos found in similar classes. ...

Peptides (from the Greek πεπτος, "digestable"), are the family of molecules formed from the linking, in a defined order, of various amino acids. The link between one amino acid residue and the next is an amide bond, and is sometimes referred to as a peptide bond. ...
