Mesonephroma - 새창
A rare tumor of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognized: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumor (called also ENDODERMAL SINUS TUMOR and yolk sac tumor), occurring chiefly in children. The latter variety may also arise in the testis. (Dorland, 27th ed)
Synonyms : Mesonephromas
Mesonephros - 새창
The excretory organ of the embryo, collective Wolffian tubules, which forms the urogenital fold from which the reproductive organs develop. The mesonephros is the permanent kidney in fish and amphibians, but atrophies in reptiles, birds, and mammals.
Synonyms : Body, Wolffian
Mesons - 새창
Short-lived elementary particles found in cosmic radiation or produced from nuclear disintegration. Their mass is between that of protons and electrons and they can be negative, positive, or neutral. pi-Mesons (pions) are heavier than mu-mesons (muons) and are proposed for cancer radiotherapy because their capture and disintegration by matter produces powerful, but short-lived, secondary radiation.
Synonyms : Meson, Muon, Pion, mu Mesons, mu-Meson, pi Mesons, pi-Meson
Mesoporphyrins - 새창
Porphyrins with four methyl, two ethyl, and two propionic acid side chains attached to the pyrrole rings.
