Japanese Tableware-from Lacquer ware to Porcelain

Insist That Your Laboratory Porcelain Ware Carry This Mark of Dependability

Nonmetabolic catalysis of C-furfuryl amino purine (kinetin) on plant surfaces, glass, and porcelain ware.

Kinetin-8-(14)C degraded rapidly upon drying on living or inert surfaces. However, when care was exercised to avoid taking solutions to dryness during fractionation of plant extracts containing (14)C-kinetin and before partitioning by thin layer chromatography, little degradation occurred. A procedure for 24-hour ethyl acetate partitioning, using a continuous liquid-liquid extractor, which perm...

Computer-Augmented Tableware to Enhance the Eating Experiences

Eating is fun. Historically, human beings have paid much attention to the process of eating and the mealtime environment, attempting to enhance the palatability of food, discover new seasonings, and create aesthetic tableware. We aim to make mealtimes more pleasant through the use of technology. We think that a gamification approach using computer technology to make everyday activities fun can ...

Stability of Japanese-lacquer-tree (Rhus vernicifera) laccase to thermal and chemical denaturation: comparison with ascorbate oxidase.

The thermal denaturation of laccase from the Japanese lacquer tree (Rhus vernicifera) was studied by differential scanning calorimetry. The endotherms of holo-laccase, type 2-Cu-depleted laccase and apo-laccase were deconvoluted into two independent two-state transitions, providing evidence for a domain structure of the protein. The correlation of the two transitions with the bleaching of coppe...

Heterogeneity of the Type 3 copper in Japanese-lacquer-tree (Rhus vernicifera) laccase.

The two steps of the titration of the Japanese-lacquer-tree (Rhus vernicifera) laccase with N3- [Morpurgo, Rotilio, Finazzi-Agrò & Mondovi (1974) Biochim. Biophys. Acta 336, 324-328; LuBien, Winkler, Thamann, Scott, Co, Hodgson & Solomon (1981) J. Am. Chem. Soc. 103, 7014-7016] were shown to be two distinct reactions, each involving one different portion of the native enzyme molecules. The diff...
