Abstract: A process for staining wood, preferably unfinished wood, and/or wood articles from which the finish has been removed, with a stain (oil or water based) containing a plurality of fluorescent dyes and/or pigment, by treating the wood with a bleach to substantially reduce the contrast between the heartwood and sapwood features of the wood grain thereof to the desired degree, and staining the bleached wood with a stain formulation containing a plurality of fluorescent dye or pigment, wherein each fluorescent dye or pigment are absorbed into the wood and produce a uniquely colored stained wood product. The staining process can be repeated, as desired, to attain the stained wood object having a distinctive wood product, in visible light, and a distinctive wood product having a, fluorescent monochromatic appearance, in the absence of visible light. In each instance the color of the stain shall appear in varying intensity depending upon the uptake thereof in the heartwood or the sapwood.

Abstract: Classes of compounds that exhibit effective inhibition of autotaxin enzymes are provided. Such classes include thioureas, diphenyldiazerenes, xanthenes, and isoindoles and exhibit reactivity with autotaxin to ultimately reduce the size of the reactive sites thereon to prevent conversion of lysophosphatidyl choline to lysophophatidic acid. Furthermore, such compounds can be incorporated within delivery forms for human ingestion. As such, these compounds accord an excellent manner of potentially reducing generation of certain cancers attributable to the presence of naturally occurring autotaxin within the human body. Methods of inactivating autotaxin to certain degrees therewith such compounds are encompassed within invention as well.
