The Karyotype Ontology: a computational representation for human cytogenetic patterns
The karyotype ontology describes the human chromosome complement as determined cytogenetically, and is designed as an initial step toward the goal of replacing the current system which is based on semantically meaningful strings. This ontology uses a novel, semi-programmatic methodology based around the tawny library to construct many classes rapidly. Here, we describe our use case, methodology...

Lectin histochemistry of human meningiomas.
The lectins Peanut agglutinin (PNA), Canavalia ensiformis (Con A), Ulex europaeus-1 (UEA-1), Dolichos biflorus (DBA), Triticum vulgaris (WGA) were studied in a series of 36 meningiomas (16 meningotheliomatous-including 3 recurrences, 7 transitional, 4 angiomatous, 2 "hemangiopericytic", 3 papillary-including 1 recurrence, 4 anaplastic-including 3 recurrences. PNA binds to all cases of meningoth...
متن کاملIsonucleolinosis in cell cultures of human meningiomas.
In cell cultures of 13 human meningiomas the internal structure of the nucleolus was stained by the toluidine blue-molybdate method and compared with the karyotype of the tumors. Although some of the meningiomas had lost or gained one or more chromosomes and had undergone structural aberrations, all of them showed isonucleolinosis, which is normally found only in cells with normal karotype. It ...
متن کاملConstancy of Chromosome Karyotype in Human Tumors
Two strains of human tumor H.Ep. #3 maintained in different laboratories were studied for chromosome composition and compared with the chromosome analysis of this tumor published by Levan in 1956. Chromosome patterns in both current strains appeared to be similar to that previously described. This demonstrates considerable stability through many animal passages. Three strains of human tumor H.A...
