    Background: The annotated genomes of two closely related strains of the intracellular bacterium Wolbachia pipientis have been reported without the identifications of the putative origin of replication (ori). Identifying ...
  • A new family of giardial cysteine-rich non-VSP protein genes and a novel cyst protein 

    Davids, Barbara J.; Reiner, David S.; Birkeland, Shanda R.; Preheim, Sarah P.; Cipriano, Michael J.; McArthur, Andrew G.; Gillin, Frances D. (Public Library of Science, 2006-12)
    Since the Giardia lamblia cyst wall is necessary for survival in the environment and host infection, we tested the hypothesis that it contains proteins other than the three known cyst wall proteins. Serial analysis of gene ...
  • A New invertebrate member of the p53 gene family is developmentally expressed and responds to polychlorinated biphenyls 

    Jessen-Eller, Kathryn; Kreiling, Jill A.; Begley, Gail S.; Steele, Marjorie E.; Walker, Charles W.; Stephens, Raymond E.; Reinisch, Carol L. (National Institute of Environmental Health Sciences, 2002-03-07)
    The cell-cycle checkpoint protein p53 both directs terminal differentiation and protects embryos from DNA damage. To study invertebrate p53 during early development, we identified three differentially expressed p53 family ...
  • New species longevity record for the northern quahog (=hard clam), Mercenaria mercenaria 

    Ridgway, Iain D.; Richardson, C. A.; Enos, Edward; Ungvari, Z.; Austad, S. N.; Philipp, E. E. R.; Csiszar, Anna (National Shellfisheries Association, 2011-04)
    Twenty-two large shells (>90 mm shell height) from a sample of live collected hard shell clams, Mercenaria mercenaria, from Buzzards Bay, Woods Hole, Cape Cod, MA, were subjected to sclerochronological analysis. Annually ...
  • A new US polar research vessel for the twenty-first century
