BACKGROUND Animal-free recombinant proteins provide a safe and effective alternative to tissue or serum-derived products for both therapeutic and biomanufacturing applications. While recombinant insulin and albumin already exist to replace their human counterparts in cell culture media, until recently there has been no equivalent for serum transferrin. (More)
We describe our efforts to use source-level rewriting to optimize run-time program generators written in Jumbo, a run-time program generation system for Java. Jumbo is a compiler written in <i>compositional</i> style, which brings the advantage that any program fragment can be abstracted out and compiled to an intermediate form. These forms can be put(More)
An integral part to understanding the biology of an invasive species is determining its origin, particularly in pest species. As one of the oldest known invasive species, the goals of this study were to evaluate the evidence of a westward expansion of Hessian fly into North America, from a potential singular introduction event, and the population genetic(More)
Understanding the mechanisms that drive acid-base regulation in organisms is important, especially for organisms in aquatic habitats that experience rapidly fluctuating pH conditions. Previous studies have shown that carbonic anhydrases (CAs), a family of zinc metalloenzymes, are responsible for acid-base regulation in many organisms. Through the use of(More)
A laboratory microcosm experiment was conducted to examine the roles of food quantity and food quality on the competitive abilities of clones of the keystone aquatic zooplankter, Daphnia pulicaria. Using methods of resurrection ecology, clones were established by hatching dormant eggs from sediment layers of a lake (South Center, MN, U.S.A) that were(More)
