The critical problem of oxygen toxicity for nitrogen-fixing organisms may be related to damage caused by oxygen radicals and peroxides. An enzymatic mechanism is described for removal of peroxides in… Expand
Association within a family of a balanced autosomal translocation with major mental illness
282 pedigrees in the MRC Cytogenetics Registry, Edinburgh, with familial autosomal anomalies were examined for the presence of associated mental illness. In one large pedigree there were 23 cases of… Expand
Current status of cytogenetic procedures to detect and quantify previous exposures to radiation.
The estimation of the magnitude of a dose of ionizing radiation to which an individual has been exposed (or of the plausibility of an alleged exposure) from chromosomal aberration frequencies… Expand
Forty four probands with an additional “marker” chromosome
SummaryInformation is presented which has been obtained from an exhaustive examination of 44 probands with a supernumerary marker chromosome (mar) and their families. The data include the derivation… Expand
Cytological detection of mutagen–carcinogen exposure by sister chromatid exchange
A staining technique that detects sister chromatid exchanges (SCEs) has been used to examine the response of chromosomes in cultured Chinese hamster cells to a wide variety of mutagens–carcinogens.… Expand
New technique for distinguishing between human chromosomes.
A GIEMSA staining procedure that preferentially stains centromeric heterochromatin in mouse chromosomes has been described1. This specificity was observed when fixed preparations were treated with… Expand
Relation between Glutamine Synthetase and Nitrogenase Activities in the Symbiotic Association between Rhizobium japonicum and Glycine max.
The activity and extent of adenylylation of glutamine synthetase was examined in both free-living and bacteroid forms of Rhizobium japonicum in the presence of excess ammonia. Ammonia caused an… Expand
Cytogenetic aspects of phylogeny in the Bovidae. I. G-banding.
An extensive G-banding study of karyotypes of 12 species of Bovidae has been undertaken in an attempt to trace homologies and patterns of evolution of karyotype phenotypes throughout the family.… Expand
