Progression of 3T3-L1 preadipocyte differentiation is divided into early (days 0-2, D0-D2), intermediate (days 2-4, D2-D4), and late stages (day 4 onwards, D4-). In this study, we investigated the effects of fucoxanthin, isolated from the edible brown seaweed Petalonia binghamiae, on adipogenesis during the three differentiation stages of 3T3-L1(More)
This study explores the anti-obesity properties of a Sasa quelpaertensis leaf extract (SQE) in high-fat diet (HFD)-induced obese C57BL/6 mice and mature 3T3-L1 adipocytes. SQE administration with HFD for 70 d significantly decreased the body weight gain, adipose tissue weight, and serum total cholesterol and triglyceride levels in comparison with the HFD(More)
We previously showed that an ethanolic extract of the edible brown algae Petalonia binghamiae promotes the differentiation of 3T3-L1 preadipocytes and decreases hyperglycemia in streptozotocin-induced diabetic mice. Here, we report that a water-soluble extract of P. binghamiae thalli, prepared by enzymatic digestion, inhibits preadipocyte differentiation(More)
In this study, we investigated the antiobesity properties of Petalonia binghamiae extract (PBE) in mice in which obesity was induced with a high-fat diet (HFD). PBE administration (150 mg/kg/day) for 70 days decreased body weight gain, adipose tissue weight, and the serum triglyceride level in mice fed a HFD. PBE reduced serum levels of glutamic pyruvic(More)
Robust pitch estimation is important in many areas of speech processing. In voice pathology, diverse statistics extracted form pitch estimation were commonly used to test voice quality. In this study, we compared several established pitch detection algorithms (PDAs) for verification of adequacy of the PDAs. In the database of total pathological voices of 99(More)
The peel of Citrus sunki HORT. ex TANAKA has been widely used in traditional Asian medicine for the treatment of many diseases, including indigestion and bronchial asthma. In this study, we investigated the antiobesity activity of immature C. sunki peel extract (designated CSE) using high-fat diet (HFD)-induced obese C57BL/6 mice and mature 3T3-L1(More)
Quantum dots are a promising new candidate for the emissive material in light-emitting devices for display applications. The fabrication of such devices by solution processing allows considerable cost reduction and is therefore very attractive for industrial manufacturers. We report all solution-processed colloidal quantum-dot light-emitting diodes (QLEDs)(More)
UNLABELLED Quantum dots (QDs) are a promising material for emissive display with low-cost manufacturing and excellent color purity. In this study, we report colloidal quantum-dot light emitting diodes (QLEDs) with an inverted architecture with a solution processed charge generation layer (CGL) of p-type polymer (tungsten oxide doped(More)
We report highly efficient inverted QLED using Al doped ZnO (AZO)/Li doped ZnO (LZO) stack electron transport layer (ETL). An introduction of LZO layer on AZO improved the current and power efficiencies of the green (G-) QLED from 10.5 to 34.0 cd A-1 and from 5.4 to 29.6 lm W-1, respectively. The red (R-), G- and blue (B-) QLEDs fabricated in this work(More)
The solar wind contributes to the formation of unique space environment called the Earth’s magnetosphere by various interactions with the Earth’s magnetic field. Thus the solar-terrestrial environment affects the Earth’s magnetic field, which can be observed with an instrument for the magnetic field measurement, the magnetometer usually mounted on the(More)
