BACKGROUND Metastatic breast cancer cells are frequently associated with osteoclast-mediated bone resorption, resulting in severe bone destruction and increased mortality in patients. Platycodin D (PD) isolated from Platycodon grandiflorum is a triterpenoid saponin with anti-cancer and anti-angiogenic potential. METHODS The in vivo activity was determined(More)
For cervical cancer screening, HPV-DNA test is expensive and is not easily available in all clinical situations. Thus, we investigated the role of p16(ink4a) immunostaining as another adjunct test to diagnose cervical neoplasia in equivocal liquid based cytology. Eighty-seven patients were randomly selected for this study (3 patients with normal, 84(More)
While a variety of plant hormones from brown algae were described, there were few studies that examined the combined effects of these hormones on morphogenesis and photosynthetic physiology in developing fucoid embryos. We evaluated the effects of phytohormones to determine the extent, to which responses were similar to those of terrestrial plants. Kinetin,(More)
It is now well known that a simple graph C *-algebra C * (E) of a directed graph E is either AF or purely infinite. In this paper, we address the question of whether this is the case for labeled graph C *-algebras recently introduced by Bates and Pask as one of the generalizations of graph C *-algebras, and show that there exists a family of simple unital(More)
An alternating current (AC) voltage modulation was applied to ion-selective observations with plasticized poly(vinyl chloride) membranes in glass nanopipettes. The liquid confronting the membranes in the nanopipettes, the conditioning process, and AC voltage modulation play important roles in the ion-selective detection. In the AC detection system developed(More)
Ion-selective electrodes (ISEs) are widely used to detect targeted ions in solution selectively. Application of an ISE to a small area detection system with a nanopipette requires a special measurement method in order to avoid the enhanced background signal problem caused by a cation-rich layer near the charged inner surface of the nanopipette and the(More)
Ion current rectification dependent on the concentration gradient of KCl solutions was systematically investigated in polyethyleneimine modified glass nano-pipettes with inner diameter of 105 nm. Peak shape dependence of the rectification factor on outer KCl solution concentration was observed when inner KCl solution with concentration from 1 mM to 500 mM(More)
