Cytogenetic Investigations on the Genus <i>Chlorophytum</i>

Cytogenetic Investigations in Couples with Male Sterility

Cytogenetic investigations of solid tumours of children.

The association of non-random chromosome abnormalities with solid tumours of childhood may improve accuracy of diagnosis and prognosis and lead to a better understanding of their biology. In a pilot study in the Northern region of England fresh tumour biopsy specimens were obtained from 39 to 72 consecutive solid tumours in children who presented over a period of 21 months. Cytogenetic analysis...

Cytogenetic investigations in four canine lymphomas.

Four cases of canine lymphoma are presented, including histological examination and cytogenetic investigation. The first case showed a derivative chromosome 13, the second case showed a clonal trisomy 8 and the third case showed a complex karyotype with a clonal trisomy 13 and additional clonal trisomies of the chromosomes 20, 30 and 37, as well as a non-clonal tetrasomy 9. Case four showed a s...

Cytogenetic study of the genus Saguinus (Callithrichidae, Primates)

Eight subspecies from the genus Saguinus (S. fuscicollis fuscicollis, S. fuscicollis weddelli, S. bicolor bicolor, S. bicolor martinsi, S. mystax mystax, S. imperator imperator, S. midas midas, and S. midas niger) were studied. Five of them (S. f. fuscicollis, S. f. weddelli, S. b. martinsi, S. m. mystax and S. i. imperator) had their karyotypes described for the first time. Conventional colora...

Molecular cytogenetic investigations of synchronous bilateral breast cancer.

BACKGROUND Bilaterality in breast cancer is a rare event and together with an early onset of disease points towards inheritance of the disease. However, most cases seem to occur sporadically, either in a synchronous or metachronous manner. METHODS Thirty two invasive carcinomas and one in situ carcinoma from 16 patients with synchronous, bilateral breast cancer were investigated by means of c...
