In I958, during breeding experiments in the Department of Genetics at Cambridge, a small -proportion of newbom offspring of backcross matings of the gene ragged (Ra, Slee, I957) developed a swollen belly. The affected animals appeared normal at birth but about 24 hours after they had begun to suckle their abdomens became swollen with an accumulation of milk-like fluid in the peritoneal cavity. ...
The Kearns-Sayre syndrome is a neuromyopathic disorder associated with mitochondrial abnormalities and characterized by the triad of chronic external ophthalmoplegia, atypical pigmentary retinopathy, and progressive conduction system disorders. Ragged red muscle fibers that seem to contain an excess of altered mitochondria are observed. The disease affects both sexes alike, during the first or ...
We study the problem of mapping array-structured data to an ensemble of parallel memory modules, by allowing at most c conflicts (i.e. simultaneous access by up to c processors to the same memory module). We seek the smallest ensemble that will allow us to store any n-vertex instance of three array-like data structures with no more than c array-vertices stored on the same module. For the most g...
SUMMARY We report 3 patients with myoclonic epilepsy with ragged-red fibers (MERRF) diagnosed by mitochondrial A8344G mutation. Cerebellar ataxia was the first symptom in all patients. Conventional brain MR imaging showed atrophy of the superior cerebellar peduncles and the cerebellum in all patients and brain stem atrophy in 2 patients. In diffusion tensor analysis, fractional anisotropy of th...
