A colonic adenocarcinoma cell line, designated GPC-16, was established in culture from tissue removed from an outbred guinea pig which received 56 mg of N-methyl-N-nitrosourea intrarectally over a 28-week period. the GPC-16 has been maintained for more than 30 in vitro passages and was tumorigenic in both the autochthonous host and nude mice. The cells were aneuploid with a wide range in chromo...

We established a cell line ( TSUS -1) derived from a relatively well-differentiated squamous cell carcinoma of the penis. The cells had been subcultured 60 times during two years and five months. The average doubling time of this cell line was 38 hours. Chromosomal analysis indicated that the modal chromosome number was 75; seven marker chromosomes and a male karyotype were present. The culture...

A continuous human renal carcinoma cell line (GKA) has been established from a patient with the paraneoplastic syndrome of erythrocytosis. The cells are epithelioid and anchorage dependent and have a doubling time in vitro of 48 to 72 hr. They exhibit a modal karyotype of 45,XX with abnormalities in chromosomes 3 and 9 and an absent chromosome 17 as determined by quinacrine mustard staining. Li...

We consider the problem of constructing balance dynamics for rapidly rotating fluid systems. It is argued that the conventional Rossby number expansion-namely expanding all variables in a series in Rossby numberis secular for all but the simplest flows. In particular, the higher-order terms in the expansion grow exponentially on average, and for moderate values of the Rossby number the expansio...
