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)
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)
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)
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)
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)
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)
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)
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)
BACKGROUND In various studies in adults, caffeine may increase wakefulness and relieve pain, but caffeine overdose can cause many adverse serious effects on health. Caffeine intake has recently been increasing in adolescents. In spite of importance of caffeine effects on Korean adolescents, there are lack of scientific and systematic studies. The purpose of(More)
