LSI78Y mouse lymphoblastic leukemia cells normally require asparagine (ASN) for growth, but phenotypically stable ASN-independent cells are detectable at low fre quency by direct cloning, in ASN-free soft-agar medium, of cells from cultures that have been grown nonselectively in medium containing ASN. The rate of mutation in vitro to ASN independence was determined by the Luria-Delbruck fluctua...

Four groups of 20 each (chronic brain-damaged schizophrenics, chronic non-brain-damaged schizophrenics, chronic non-brain-damaged with "acute" exacerbation, and control subjects) were individually administered Form I of the Luria Nebraska Neuropsychological Battery (LNNB). Control subjects scored significantly lower than all clinical groups on all scales except for the chronic non-brain-damaged...

Luria has described a syndrome of disinhibited and impulsive behaviour, in which the patient is unable to follow sequential instructions. This he attributes to localised frontal lobe damage. However, group studies of patients with focal lesions of the frontal lobes fail to reveal such a syndrome. A patient is described who displayed a form of Luria's syndrome temporarily. Psychometric and post ...

The lions of the field have published seminal work in our journal, from Bridges, Muller, and McClintock to Brenner, Horvitz, and Hartwell. Authors can publish in the same journal as did Luria and Delbruck, and Sewall Wright, and Ronald Fisher, and Crow and Kimura (and many other luminaries). And while GENETICS provides a professional and scientific thread that extends back to the founders of ou...
