The interaction between NS1B protein of influenza B virus and the ubiquitin-like modifier ISG15 : insights into a unique species specific property of the virus
… lines. This result led to the discovery of the species specific nature of the interaction between NS1B and ISG15. Specifically, NS1B was found to bind ISG15 homologs from human and old world monkeys like Rhesus macaques and African green monkeys but not those from mouse or canines. These …

Development of a synthetic enzyme for detection and quantitation of Thiols
… monotosylate of $\beta$-cyclodextrin yielded unique species based on RP-HPLC, and UV-Visible spectroscopy. After isolation by RP-HPLC, synzymes were examined for thiol oxidation under pseudo-first order conditions, and thiol oxidation rates were determined. Only the secondary …

Collaborative Conservation of Taimen (Hucho taimen)Through Education and Awareness Khovsgol Aimag Mongolia
… of 6.5 ft. and weighing as much as 200 lbs This unique species of fish is incredibly slow-growing, long-lived (up to 40 years) and late to reach sexual maturity (5-7 years). These characteristics -- coupled with overuse and habitat loss -- have resulted in a drastic species decline throughout its …

Analysis of seabird observation and satellite tracking data in the Falkland Islands to assess suitability for proposing Marine Important Bird Areas
… dataset sets to examine whether sites of high species numbers or abundance were linked to seabed bathymetry, to assess whether listed threatened species were found in particular locations, and to discover if any areas showed evidence of hotspot foraging locations for multiple species. The study …

2D layout of bead based thioaptamer/aptamer selection platform for therapeutics and diagnostics
… library, in which every bead contains a unique species of aptamers, provides a promising platform for selection of aptamers and thioaptamers. To successfully screen the bead-based library, 2D layout of beads in gel and on bead screening model is proposed. To develop the 2D layout of beads …

Abundance Trends and Drivers of Change in Freshwater Fish Communities of the New River Basin
Habitat destruction/alteration and non-native species are widely considered the two most serious threats to biodiversity within freshwater ecosystems, which are among the most threatened in the world. I examined the effects of these factors, specifically focusing on land use and non-native species …
