      INTRODUCTION: The syndrome of fever is a commonly presenting complaint among persons seeking healthcare in low-resource areas, yet the public health community has not approached fever in a comprehensive manner. In many areas, ...
    • FtsZ in bacterial cytokinesis: cytoskeleton and force generator all in one. 

      Erickson, Harold P; Anderson, David E; Osawa, Masaki (Microbiology and molecular biology reviews : MMBR, 2010-12)
      FtsZ, a bacterial homolog of tubulin, is well established as forming the cytoskeletal framework for the cytokinetic ring. Recent work has shown that purified FtsZ, in the absence of any other division proteins, can assemble ...
    • Hybrid error correction and de novo assembly of single-molecule sequencing reads. 

      Koren, Sergey; Schatz, Michael C; Walenz, Brian P; Martin, Jeffrey; Howard, Jason T; Ganapathy, Ganeshkumar; Wang, Zhong; ... (11 authors) (Nat Biotechnol, 2012-07-01)
      Single-molecule sequencing instruments can generate multikilobase sequences with the potential to greatly improve genome and transcriptome assembly. However, the error rates of single-molecule reads are high, which has limited ...
    • IGHV1-69 B cell chronic lymphocytic leukemia antibodies cross-react with HIV-1 and hepatitis C virus antigens as well as intestinal commensal bacteria.
