Lipid microdomains or caveolae, small invaginations of plasma membrane, have emerged as important elements for lipid uptake and glucose homeostasis. Sphingomyelin (SM) is one of the major phospholipids of the lipid microdomains. In this study, we investigated the physiological function of sphingomyelin synthase 2 (SMS2) using SMS2 knock-out mice, and we(More)
Kokuto-shochu is a traditional Japanese distilled liquor made from brown sugar. Kokuto-shochu distillery wastewater (KDW) contains high concentrations of organic compounds and brown pigments (called molasses pigments) which are hardly decolorized by general biological wastewater treatment. A fungus, Penicillium oxalicum d, which we isolated in a previous(More)
The Hiyama cross-coupling reaction of (E)-trimethyl(3,3,3-trifluoroprop-1-enyl)silane (1) with 2-iodoaniline (2) proceeded without any protection of the amino group. The coordination of copper(II) fluoride to 2,2'-bipyridyl provided the fluoride source required to trigger this reaction, affording (E)-2-(3,3,3-trifluoroprop-1-enyl)aniline (3). In the(More)

OBJECTIVE The aim of this study was to investigate the therapeutic effects of a Sasa veitchii leaf extract (SE) on carbon tetrachloride (CCl4)-induced hepato- and nephrotoxicity. METHODS Seven-week-old male ddy mice were orally administered SE or saline for seven days. Twenty-four hours after the last SE or saline administration, the mice were(More)
A rare case of simple ulcer of the colon in a 7-year-old girl is reported. Simple ulcer is clinically and pathologically recognized as a serious disease linked to intestinal Behcet's disease. Recently, some immunomodulators, such as thalidomide and antitumor necrosis factor monoclonal antibody, have been used to treat Behcet's disease, with varying degrees(More)
Several studies have shown that docosahexaenoic acid (DHA) attenuates epileptic seizures; however, the molecular mechanism by which it achieves this effect is still largely unknown. DHA stimulates the retinoid X receptor, which reportedly regulates the expression of cytochrome P450 aromatase (P450arom). This study aimed to clarify how DHA suppresses(More)
Restless legs syndrome (RLS) is one of the common nocturnal disturbance seen in Parkinson's disease (PD) patients. The prevalence of RLS with PD is greater than that of general populations; however, etiology of RLS in patients with PD is still controversial. We report a 63-year-old man with PD, who was admitted to our hospital with uncontrollable unpleasant(More)
A protocol for the direct synthesis of azepines using a hafnium(III)-catalyzed [6 + 1] annulation of N-tethered ynenitriles with Reformatsky reagents is reported. A broad range of 3-amino-2,7-dihydro-1H-azepine-4-carboxylates 4aa-4he were obtained in high yields and with excellent functional group tolerance. The copper-mediated reactions of isolable Blaise(More)
