Abstract:
... An expedient regio-, stereo- and product-selective synthesis of novel hybrid heterocyclic systems comprising [1,2-c]oxazolidine, pyrrolidine and piperidine units, in good to excellent yields, has been developed via three-component 1,3-dipolar cycloaddition/annulation domino reactions and concomitant trifluoroacetic acid mediated condensative annulation with paraformaldehyde. These novel structural ...

Abstract:
... Shiga toxin-producing Escherichia coli (STEC) are frequent causes of severe human diseases ranging from diarrhea to hemolytic uremic syndrome. The existing strategy for detection of STEC relies on the unique sorbitol-negative fermentation property of the O157 strains, the most commonly identified serotype has been E. coli O157. It is becoming increasingly evident, however, that numerous non-O157 S ...

Five fields were sampled in 2006: a managed native pasture (NP), two pastures that were previously cropped and then seeded to Coastal bermudagrass [Cynodon dactylon (L.) Pers.] for the past 57 (CB) or 31 (CBTL) yr, and tw ...

A U1A mutant (ΔK50ΔM51) binds U1hpII-derived hairpins with shorter loops, making it an interesting scaffold for engineering or evolving proteins that bind similarly sized disease-related hairpin RNAs. However, a more detailed understanding of complexes involving ΔK50ΔM51 is likely a prerequisite to generating such proteins. Toward this end ...
