Voltage-activated ion channels are essential for electrical signaling, yet the mechanism of voltage sensing remains under intense investigation. The voltage-sensor paddle is a crucial structural motif in voltage-activated potassium (K(v)) channels that has been proposed to move at the protein-lipid interface in response to changes in membrane voltage. Here(More)
The anti-inflammatory and neuroprotective effects of trans-cinnamaldehyde (TCA) were investigated on the inflammatory cells and the dopaminergic degeneration in mice. TCA inhibited the up-regulation of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in the lipopolysaccharide (LPS)-induced inflammatory BV2 microglial cells. To investigate(More)
Knowledge regarding the genetic risk loci for gestational diabetes mellitus (GDM) is still limited. In this study, we performed a two-stage genome-wide association analysis in Korean women. In the stage 1 genome scan, 468 women with GDM and 1,242 nondiabetic control women were compared using 2.19 million genotyped or imputed markers. We selected 11 loci for(More)
BACKGROUND Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that regulates various cellular processes such as cell survival, angiogenesis and proliferation. In the present study, we examined that betulinic acid (BA), a triterpene from the bark of white birch, had the inhibitory effects on hypoxia-mediated activation of(More)
Although nerve growth factor (NGF) therapy is an available option for the treatment of Alzheimer's disease, several limitations exist in its medical application. In the present study, we examined the neurotrophic effects of spicatoside A isolated from Liriope platyphylla on PC12 cells as well as the mechanisms involved in this process. Spicatoside A (10(More)
Nerve growth factor (NGF) decreases degeneration of cholinergic neurons, improves memory loss, and increases long-term potentiation and learning tasks. Therefore, NGF mimetics or NGF inducers may be important targets for the treatment of various neurodegenerative disorders. Traditionally, Gongjin-dan (GJD) has been used clinically for the treatment of(More)
It has been shown that acupuncture at acupoints GB34 and LR3 inhibits the degeneration of nigrostriatal neurons in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinson's disease. The degeneration of spinal cord was reported to be induced in the MPTP-treated pre-symptomatic mouse. In this study, the gene expression profile changes(More)
BACKGROUND Myolysis is one of the procedures that is claimed to provide significant improvement in myoma status without hysterectomy. Myolysis procedures have been generally performed via laparoscopy, and there are limited data on transvaginal radiofrequency (RF) myolysis. This study investigated the feasibility, efficacy and safety of transvaginal(More)
For the surface-optoelectronic study of Saxitoxin sensing, we fabricated self-assembled calix[4]arene derivative monolayers as the recognition-functional interfaces on a gold surface. An interaction study between Saxitoxin and calix[4]arene derivative monolayers were performed using surface plasmon resonance (SPR) spectroscopy. Among three calix[4]arene(More)
BACKGROUND Interleukin (IL)-18 is an important regulator of innate and acquired immune responses and has multiple roles in chronic inflammation and autoimmune disorders. Obesity is characterized by low- grade chronic inflammation. IL-18 has been suggested as an adipogenic cytokine that is associated with excess adiposity. The purpose of this study is to(More)
