Comparative analysis of multiple genomes in a phylogenetic framework dramatically improves the precision and sensitivity of evolutionary inference, producing more robust results than single-genome analyses can provide. The genomes of 12 Drosophila species, ten of which are presented here for the first time (sechellia, simulans, yakuba, erecta, ananassae,(More)
Cardiac amyloidosis, a restrictive heart disease with high mortality and morbidity, is underdiagnosed due to limited targeted diagnostic imaging. The primary aim of this study was to evaluate the utility of 18F-florbetapir for imaging cardiac amyloidosis. We performed a pilot study of cardiac 18F-florbetapir PET in 14 subjects: 5 control subjects without(More)
UNLABELLED Various methodological approaches have estimated the incidence of osteoporosis-related fractures, making comparisons difficult. This study estimated the incidence rates of non-traumatic fractures in 12 countries using standard definitions. Applying these rates to the 2010 population figures of these countries, a total of 5.2 million non-traumatic(More)
Adult white male residents of 13 counties of western Washington State in whom germ cell testicular cancer was diagnosed between 1977 and 1983 (n = 333) were interviewed by telephone regarding their history of cryptorchism and its treatment. The same interview was given to a sample of 675 men selected from the population of these counties by dialing(More)
To investigate what role a man's occupation may have on his risk of testicular cancer, we conducted a case-control study among noncryptorchid white males who were between 20 and 69 years of age and resided in western Washington State. Cases were men in whom a germ cell tumor of the testis was diagnosed between 1977 and 1984 (n = 323). Their occupational(More)
To investigate the possible association between residential formaldehyde exposures and risk of cancer of the oro- and hypopharynx (OHPC, N = 205), nasopharynx (NPC, N = 27) and sinus and nasal cavity (SNC, N = 53), a population-based case-control investigation was carried out in 13 counties of western Washington. Controls (N = 552) were selected by random(More)
A population-based case-control study was undertaken in 13 counties of western Washington to determine if occupational formaldehyde exposure was related to cancer of the oro- and hypopharynx (OHPC, N = 205), nasopharynx (NPC, N = 27) or sinus and nasal cavity (SNC, N = 53). Controls were selected by random digit dialing (N = 552). A telephone interview(More)
UNLABELLED In nine industrialized countries in North America, Europe, Japan, and Australia, country-specific osteoporosis prevalence (estimated from published data) at the total hip or hip/spine ranged from 9 to 38 % for women and 1 to 8 % for men. In these countries, osteoporosis affects up to 49 million individuals. PURPOSE Standardized country-specific(More)
Adult male residents of 13 counties of western Washington state in whom testicular cancer had been diagnosed during 1977-1983 (n = 333) were interviewed over the telephone regarding their history of genital tract conditions, including vasectomy. For comparison, the same interview was given to a sample of 729 men selected from the population of these(More)
The possibility that intrascrotal temperature is involved in the etiology of testicular cancer was investigated through a population-based case-control study conducted in western Washington State. A total of 323 men with germ cell tumors of the testis diagnosed between 1977 and 1984 and 658 randomly selected controls were interviewed with regard to type of(More)
