P1 blood group antigen expression and epidemic hemolytic uremic syndrome

P1 blood group positivity has been postulated as a host factor which may provide protection against the development of post-enteropathic hemolytic uremic syndrome (HUS). In this study, blood group status in 20 Inuit survivors ofEscherichia coli 0157: H7-associated HUS was compared with age-and sex-matched controls from the same community who had experienced uncomplicated diarrheal illness due to the same pathogen. Of 20 HUS survivors, 6 were P1 antigen positive compared with 8 of the 20 controls (P=0.7). We conclude that P1 antigen positivity was not protective against HUS in this population. Further studies of this condition to clarify the role of host factors in verotoxin-induced endothelial damage are indicated.

Fracture resistance and 2-body wear of 3-dimensional–printed occlusal devices

Statement of problem

Polymeric material for 3-dimensional printing can be used to fabricate occlusal devices. However, information about fracture resistance and wear is scarce.

Microsatellite markers for Longfin Dace, Agosia chrysogaster, a sentinel fish species in imperiled arid-land rivers of the Sonoran Desert

We isolated and characterized 16 microsatellite DNA loci in Longfin Dace, Agosia chrysogaster, a minnow native to Sonoran Desert streams (southwestern US and northwestern Mexico). After optimization, all primer pairs produced consistently scorable products. Genetic diversity metrics were determined for each locus using 50 individuals from two populations in the Gila River basin, New Mexico. Allelic richness ranged from 2 to 37 and observed heterozygosity ranged from 0.08 to 0.95 across loci. These microsatellites offer a powerful tool to study effects of habitat fragmentation, dewatering, and climate change on population connectivity and genetic diversity in this species. Moreover, Longfin Dace co-occurs with more geographically restricted and endangered desert fish species. Genetic information for Longfin Dace could provide an important comparative dataset to assist conservation and management of other imperiled fishes in the region.
