TL;DR: The results suggest that one or more loci on the Y chromosome found on haplogroup Y-I have an effect on AIDS progression and treatment responses in European Americans.
Journal ArticleDOI

TL;DR: While SLC22A1 expression does not appear to affect response, alterations in its splicing or amino acid sequence may do so.
Journal ArticleDOI

Naoya Yuhki,Stephen J. O'Brien +1 more
TL;DR: A comparative analysis of class I and class II genes in domestic cat populations using molecular probes of the MHC from man and mouse affirm the linkage conservation of theMHC-containing linkage group in the three mammalian orders.
Journal ArticleDOI
Arthroscopic removal of an osteoid osteoma of the shoulder.
TL;DR: With this technique, areas that are often difficult to expose in an open fashion and those previously deemed inaccessible arthroscopically are localized readily and thought should be given to the possibility ofArthroscopic retrieval or excision before proceeding with open surgery.
Journal ArticleDOI
