The role of complement in the pathogenesis of diabetes was studied in 31 Type 1 (insulin-dependent) diabetic children by assaying serum islet cell surface antibody, C3, C4 and serum complement-dependent antibody-mediated cytotoxicity. Nine of 21 islet cell surface antibody-positive children were within 5 months of disease onset and showed significantly(More)
BACKGROUND The acetylcholine-activated K(+) current (I(K,ACh)) is a novel candidate for atrial-specific antiarrhythmic therapy. The present study investigates the involvement of I(K,ACh) in atrial fibrillation (AF) using NTC-801, a novel potent and selective I(K,ACh) blocker. METHODS AND RESULTS The effects of NTC-801, substituted(More)
The present study examines the effects of NTC-801, a highly selective acetylcholine (ACh) receptor-activated potassium (KACh) channel blocker, on atrial fibrillation (AF) in a canine model with electrical remodeling. An experimental substrate for AF was created in dogs via left atrial (LA) tachypacing (400 bpm, 3-5 weeks). NTC-801, dofetilide, and(More)
This study focused on the effects of tacalcitol (1,24 (R) (OH)2D3, TV-02) ointment (20 micro g/g) on cutaneous inflammation, epidermal proliferation, and differentiation and compared them with tacalcitol ointment (2 micro g/g) and other anti-psoriatic ointments using hairless mice. Tacalcitol ointment (0, 2 and 20 micro g/g) significantly inhibited(More)
BACKGROUND The diagnosis of Immunoglobulin G4 (IgG4)-related disease (IgG4-RD), in general, depends on serum IgG4 concentrations and histopathological findings; therefore, diagnosis of IgG4-RD in cardiovascular organs/tissues is often difficult owing to the risk of tissue sampling. METHODS Prevalence of IgG4-positive lymphoplasmacytic infiltration in 103(More)
