    摘要: A device for reducing wear to the inner wall of a cyclone separator by causing a protective layer of particulate to accumulate along the inner wall. The protective layer is facilitated by securing an expanded metal sheet along the inner wall of a cyclone separator. Once formed the protective layer of particulate acts as a shield and cushion to high-energy kinetic particles as they continue to enter the cyclone separator. The high-energy particles strike the accumulated particulate without harming the inner wall of the cyclone separator.

    摘要: The present invention relates to methods for producing inhibitors for protein deacetylases, and to the compounds and/or products produced by such methods. More specifically, the present invention relates to methods for producing inhibitors for human class III protein deacetylases or sirtuins, and to the compounds and/or products produced by such methods. The present invention provides the transformation of peptide substrates to potent peptide inhibitors by replacement of Nε-thioacetyl-lysine for Nε-acetyl-lysine.

    摘要: The present invention relates to the development of a novel assay for determining the activity of human histone deactylase 8 (HDAC8). As shown in FIG. 3, thioactyl-lysine-containing peptide is used as the substrate for the HDAC8-catalyzed dethioacetylation reaction. Thioacetate, which is formed during this reaction, is subsequently reacted with Ellman's reagent, 5,5′-dithiobis(2-nitrobenzoate), (DTNB) with a quantitative formation of 2-nitro-5-thiobenzoate (TNB). The concentration of thioacetate formed during the conversion reaction can be quantified by measuring the absorbance of TNB at 412 nm.
