The authors reviewed the psychological research on envy. The authors examined definitional challenges associated with studying envy, such as the important distinction between envy proper (which contains hostile feelings) and benign envy (which is free of hostile feelings). The authors concluded that envy is reasonably defined as an unpleasant, often painful(More)
The anti-diabetic effect of Cinnamomi cassiae extract (Cinnamon bark: Lauraceae) in a type II diabetic animal model (C57BIKsj db/db) was studied. Cinnamon extract was administered at different dosages (50, 100, 150 and 200 mg/kg) for 6 weeks. It was found that blood glucose concentration is significantly decreased in a dose-dependent manner (P<0.001) with(More)
Hereditary hearing loss is one of the most common birth defects, yet the majority of genes required for audition is thought to remain unidentified. Ethylnitrosourea (ENU)-mutagenesis has been a valuable approach for generating new animal models of deafness and discovering previously unrecognized gene functions. Here we report on the characterization of a(More)
In the process of screening for pancreatic lipase inhibitors, which could be used as an anti-obesity measure, the methanol extract of Dioscorea nipponica Makino powder (DP) appeared to have potent inhibitory activity against porcine pancreatic lipase with an IC50 value of 5-10 microg/ml, where the enzyme activity was assayed by using 4-methylumbelliferyl(More)
Metabolic disorders such as obesity are major obstacles in improving the average life span. Therefore, a therapeutic approach using natural compounds has been proposed as a novel strategy for preventing metabolic disorders. Ginsenoside Rh2 is one of the ginsenosides that exert anti-diabetes, anti-inflammatory, and anti-cancer effects. However, the(More)
Autophagy plays important roles in both cell death and cell survival. Beclin-1, a key regulator of autophagy formation, has been considered as a haploinsufficient tumor suppressor. Loss of expression or point mutation could serve as a mechanism of loss of beclin-1 tumor suppressor function in cancers. However, our recent study revealed that point mutation(More)
PURPOSE To assess lethal hepatic injury by combined treatment of radiation (RT) plus chemotherapy in a rat model with thioacetamide (TAA)-induced liver cirrhosis. METHODS AND MATERIALS Male Wistar rats were treated with 0.3 g/L TAA in drinking water. The development of liver cirrhosis was histologically confirmed, and the degree of liver function(More)
The branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder characterized by the association of branchial cysts or fistulae, external ear malformation and/or preauricular pits, hearing loss, and renal anomalies. Mutations in the EYA1 gene on the chromosome band 8q13.3, the human homologue of the Drosophila eyes absent (eya) gene, have been(More)
The antidiabetic effect of the Citrus junos Tanaka (also known as yuja or yuzu) was examined. Ethanol extract of yuja peel (YPEE) significantly stimulated 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-D-glucose (2-NBDG) uptake in C2C12 myotubes. However, ethanol extract of yuja pulp (YpEE) and water extract of yuja peel (YPWE) or pulp (YpWE) did(More)
In previous study, the anti-diabetic effect of Cinnamomi Cassiae extract (Cinnamon bark: Lauraceae) in a type II diabetic animal model (C57BIKsj db/db) has been reported. To explore their mechanism of action, in present study, the effect of cinnamon extract on anti-hyperglycemia and anti-hyperlipidemia was evaluated by measuring the blood glucose levels,(More)
