The complete TCR alpha/delta locus of Atlantic salmon (Salmo salar) has been characterized and annotated. In the 900 kb TCR alpha/delta locus, 292 Valpha/delta segments and 123 Jalpha/delta segments were identified. Of these, 128 Valpha/delta, 113 Jalpha, and a Jdelta segment appeared to be functional as they lacked frame shifts or stop codons. This… (More)
BACKGROUND The products of cyp19, dax, foxl2, mis, sf1 and sox9 have each been associated with sex-determining processes among vertebrates. We provide evidence for expression of these regulators very early in salmonid development and in tissues outside of the hypothalamic-pituitary-adrenal/gonadal (HPAG) axis. Although the function of these factors in… (More)
BACKGROUND The Atlantic salmon (Salmo salar) immunoglobulin heavy chain (IgH) locus possesses two parallel IgH isoloci (IGH-A and IGH-B), that are related to the genomic duplication event in the family Salmonidae. These duplicated IgH loci in Atlantic salmon provide a unique opportunity to examine the mechanisms of genome diversity and genome evolution of… (More)
Human papillomavirus (HPV) type 16 and 18 neutralizing antibody (NAb) titers were measured in 1,020 prenatal women in British Columbia aged 15 to 39. HPV 16 and 18 NAbs were detected in 183/1,020 (17.9%) and 97/1,020 (9.5%), respectively, and 39 (3.8%) had NAbs to both types. Titers were similar across age strata.
