In macroautophagy, cytoplasmic components are delivered to lysosomes for degradation via autophagosomes that are formed by closure of cup-shaped isolation membranes. However, how the isolation membranes are formed is poorly understood. We recently found in yeast that a novel ubiquitin-like system, the Apg12-Apg5 conjugation system, is essential for(More)
This article describes a design and implementation of an augmented desk system, named EnhancedDesk, which smoothly integrates paper and digital information on a desk. The system provides users an intelligent environment that automatically retrieves and displays digital information corresponding to the real objects (e.g., books) on the desk by using computer(More)
Macroautophagy is the major intracellular degradation system delivering cytoplasmic components to the lysosome/vacuole. We have shown that, in yeast and mammalian cells, the Apg12-Apg5 protein conjugate, which is formed by a ubiquitin-like system, is essential for autophagosome formation. In yeast, the Apg12-Apg5 conjugate interacts with a small coiled-coil(More)
A set of homozygous diploid deletion mutants of the yeast Saccharomyces cerevisiae was screened for the genes required for tolerance to aliphatic alcohols. The screen identified 137, 122 and 48 deletion mutants sensitive to ethanol, 1-propanol and 1-pentanol, respectively. A number of the genes required for ethanol tolerance were those also required for(More)
To compare NADH-regeneration systems for the synthesis of (S)-4-chloro-3-hydroxybutanoate (ECHB), a novel NADH-dependent carbonyl reductase (KaCR1), which reduced ethyl 4-chloroacetoacetate (ECAA) to form (S)-ECHB, was screened and purified from Kluyveromyces aestuarii and a gene encoding KaCR1 was cloned. Glucose dehydrogenase (GDH) and formate(More)
In this paper, we introduce a fast and robust method for tracking positions of the centers and the ngertips of both right and left hands. Our method makes use of infrared camera images for reliable detection of user's hands, and uses template matching strategy for nding ngertips. This method is an essential part of our augmented desk interface in which a(More)
The sodium-glucose cotransporter 2 (SGLT2) is responsible for most glucose reabsorption in the kidney and has been proposed as a novel therapeutic target for the treatment of type 2 diabetes. In the present study, the therapeutic effects of SGLT2 selective inhibitor ipragliflozin were examined in high-fat diet and streptozotocin-nicotinamide-induced type 2(More)
This paper describes two interface prototypes which we have developed on our augmented desk interface system, EnhancedDesk. The first application is Interactive Textbook, which is aimed at providing an effective learning environment. When a student opens a page which describes experiments or simulations, Interactive Textbook automatically retrieves digital(More)
Evodiamine, an alkaloidal component extracted from the fruit of Evodiae fructus (Evodia rutaecarpa Benth., Rutaceae), exhibits antiproliferative, antimetastatic, and apoptotic activities through a poorly defined mechanism. Because several genes that regulate cellular proliferation, carcinogenesis, metastasis, and survival are regulated by nuclear(More)
