BACKGROUND AND PURPOSE There are a few reports regarding the outcome evaluation of balloon-expandable intracranial stent placement (BEICS). The purpose of our study was to evaluate the outcome and factors related to the adverse events (AEs) of BEICS. MATERIALS AND METHODS We evaluated 100 consecutive patients who underwent BEICS. We assessed the(More)
14037 Background: Several studies have shown the efficacy of capecitabine and irinotecan combination chemotherapy for advanced colorectal cancer, while no results have yet been reported for advanced gastric cancer. Accordingly, the current study evaluated the efficacy and safety of a combination regimen of capecitabine plus irinotecan in patients with(More)
The extension of both median and maximum lifespan and the suppression of age-related diseases in laboratory animals by reduced food intake, i.e., calorie restriction (CR) are regarded as hallmarks of CR's anti-aging action. The diverse efficacy of CR to counteract aging effects and its experimental reproducibility has made it the gold standard of many aging(More)
Unidirectional electric current flow, such as that found in a diode, is essential for modern electronics. It usually occurs at asymmetric interfaces such as p-n junctions or metal/semiconductor interfaces with Schottky barriers. We report on a diode effect associated with the direction of bulk electric polarization in BiFeO3: a ferroelectric with a small(More)
Resveratrol has been shown to induce anti-proliferation and apoptosis of human cancer cell lines. In the present study, we determined the effect of high intracellular levels of the anti-apoptosis protein Bcl-2 on caspase-3 activation, PLC-gamma1 degradation and cytochrome c release during resveratrol-induced apoptosis. For this, we used U937/vector and(More)
BACKGROUND Adiponectin is a protein secreted by adipose cells that improves insulin sensitivity and possesses antiatherogenic properties. In this study, we investigated the relationship between adiponectin levels and ischemic stroke subtype. METHODS Using clinical, imaging, and laboratory data, 231 consecutive patients admitted to a university medical(More)
BACKGROUND The underlying mechanisms involved in the activation of hypoxia-inducible factor-1 (HIF-1) in gastric cancer remain unclear. As nuclear factor-κB (NF-κB) as well as HIF-1 have been implicated in angiogenesis of various cancers, we investigated their relationship in gastric cancer. METHODS Nuclear expressions of HIF-1α and NF-κB/RelA were(More)
We report discovery of collinear-magnetism-driven ferroelectricity in the Ising chain magnet Ca3Co2-xMn(x)O6 (x approximately 0.96). Neutron diffraction shows that Co2+ and Mn4+ ions alternating along the chains exhibit an up-up-down-down ( upward arrow upward arrow downward arrow downward arrow) magnetic order. The ferroelectricity results from the(More)
OBJECTIVE To evaluate whether hyperhomocysteinemia is an independent risk factor for silent brain infarction (SBI), and to determine the relationship between homocysteine and folate in each type of methylenetetrahydrofolate reductase (MTHFR) polymorphism, in order to identify a way of reducing the risk for SBI. METHODS The authors enrolled 161 patients(More)
BACKGROUND This prospective, phase II trial evaluated the efficacy and safety of dovitinib in patients with metastatic and/or unresectable gastrointestinal stromal tumours (GISTs) after failure of at least imatinib and sunitinib. METHODS Patients received oral dovitinib, 500 mg once daily, for 5 consecutive days, followed by a 2-day rest, every 28 days.(More)
