Journal ArticleDOI
Chromosomal localization of the genes encoding two forms of the G protein β polypeptide, β1 and β3, in man
TL;DR: The present studies were designed to determine whether the gene encoding beta 3 is linked to either the beta 1 or the beta 2 gene, and indicate that there is considerable diversity in the genomic organization of the beta subunit family.
Journal ArticleDOI
Risk Factors for Early Failure after Thermal Capsulorrhaphy
TL;DR: Thermal capsular shrinkage may be of limited value for patients who have had prior operations or have a history of multiple dislocations, and should be used cautiously in patients with multidirectional instability or in those who are involved in contact sports.
Journal ArticleDOI
The Pattern of Phylogenomic Evolution of the Canidae
TL;DR: Zoo-FISH probes from flow-sorted chromosomes of the Japanese raccoon dog are used to examine two phylogenetically divergent canids, indicating an ancestral episode of extensive centric fission leading to an ancestral canid genome organization that was subsequently reorganized by multiple chromosome fusion events in some but not all Canidae lineages.
Journal ArticleDOI
Segmental aneuploidy as a probe for structural genes in Drosophila: mitochondrial membrane enzymes.
TL;DR: A method for detecting possible structural genes in D. melanogaster based on gene dosage dependency is presented, and by making thirty crosses between Y-autosome translocations, and an attached-4 cross, it is possible to produce large duplications for every autosomal region with the exception of 83DE.
Journal ArticleDOI

TL;DR: The improved RH comparative map provides a useful tool to facilitate positional cloning studies in the feline model and refined the pseudoautosomal region and boundary in the cat and show that it is markedly longer than those of human or mouse.
