Stearoyl-CoA desaturase1 (SCD1) whole body deficiency protects mice from diet-induced obesity. However the specific mechanism of how SCD1 deficiency protects mice from obesity is not clear yet. To understand the tissue-specific role of SCD1 in energy homeostasis, we investigated the responses of adipocytes, hepatocytes and myotubes to SCD1 inhibition.(More)
Changes in intracellular Ca2+ level are involved in a number of intracellular events, including triggering of apoptosis. The role of intracellular calcium mobilization in cisplatin-induced hair cell death, however, is still unknown. In this study, the effect of calcium channel blocker flunarizine (Sibelium), which is used to prescribe for vertigo and(More)
4-Hydroxyphenylpyruvate dioxygenase (HPPD) is a Fe(II)-dependent, non-heme oxygenase that converts 4-hydroxyphenylpyruvate to homogentisate. Essential cofactors, such as plastoquinone and tocopherol, are produced by HPPD-dependent anabolic pathways in plants. To isolate a novel hppd using culture-independent method, a cosmid metagenomic library was(More)
BACKGROUND Sophorae Flos (SF) is a composite of flowers and buds of Styphnolobium japonicum (L.) Schott and has been used in traditional Korean and Chinese medicine for the treatment of hemostasis and inflammation. Previous studies reported that SF possesses anti-obesity properties, as well as anti-allergic, anti-proliferative, and anti-inflammatory(More)
We examined the effects of Rhizoma Dioscoreae Tokoronis extracts (RDTEs) on plasma lipids, body weight, and lipogenic enzymes. Mice were administered a standard chow diet, a 60% high-fat diet, or a high-fat diet with RDTE. Mice that were fed a high-fat diet containing RDTE were found to have lower increases in body and epididymal adipose tissue weights and(More)
BACKGROUND Multiple studies have reported that allografts are acceptable alternatives to autografts for anterior cruciate ligament (ACL) reconstructions. Our clinical practice allows patient involvement in graft decision-making. This study examined the patients' preference for graft selection and the factors affecting their decision. METHODS Patients(More)
This study investigates the inhibitory effects of Korean mistletoe extract (KME) on adipogenic factors in 3T3-L1 cells and obesity and nonalcoholic fatty liver disease (NAFLD) in mice fed a high-fat diet. Male C57Bl/6 mice fed a high-fat diet were treated with KME (3 g/kg/day) for 15 weeks for the antiobesity and NAFLD experiments. Body weight and daily(More)
OBJECTIVES The purpose of this study is to analyze clinical impact factors on the survival rate, and to acquire basic clinical data for the diagnosis of oral cancer, for a determination of the treatment plan with long-term survival in oral cancer patients. MATERIALS AND METHODS Through a retrospective review of the medical records, the factors for(More)
Inonotus obliquus has been traditionally used for treatment of metabolic diseases; however, the mechanism remains to be elucidated. In this study, we found that the water-soluble melanin complex extracted from I. obliquus improved insulin sensitivity and reduced adiposity in high fat (HF)-fed obese mice. When the melanin complex was treated to 3T3-L1(More)
The objectives of this study were to summarize the curriculum, history, and clinical researches of Chuna in Korea and to ultimately introduce Chuna to Western medicine. Information about the history and insurance coverage of Chuna was collected from Chuna-related institutions and papers. Data on Chuna education in all 12 Korean medicine (KM) colleges in(More)
