A simple procedure with a new selective culture medium for the isolation of the suspected etiological agent of Lyme disease from ticks is described. Live ticks (Ixodes dammini) were ground with a mortar and pestle, and the suspensions were inoculated into a selective and nonselective medium. The selective medium, which contained kanamycin and 5-fluorouracil, yielded positive spirochete cultures...

The broad study of histone deacetylases in chemistry, biology and medicine relies on tool compounds to derive mechanistic insights. A phylogenetic analysis of class I and II histone deacetylases (HDACs) as targets of a comprehensive, structurally diverse panel of inhibitors revealed unexpected isoform selectivity even among compounds widely perceived as nonselective. The synthesis and study of ...

We report the nonselective plasma etching of epitaxial GaN:Mg, Al0.63Ga0.37N, and AlN/Al0.08Ga0.92N short-period superlattices with various doping properties. Etching is performed using mixed CF4/Ar feed gases in a combined inductively coupled plasma and reactive-ion etching chamber. A uniform etch rate of ,23 nm/min is obtained for each of the compositions studied under identical conditions. T...

Low-temperature C-S bond cleavage at low exposure ultimately results in nonsele...
