In this study, we examined the signaling pathways activated by Wnt5a in endothelial differentiation of embryonic stem (ES) cells and the function of Wnt5a during vascular development. We first found that Wnt5a(-/-) mouse embryonic stem (mES) cells exhibited a defect in endothelial differentiation, which was rescued by addition of Wnt5a, suggesting that(More)
BACKGROUND The common p53 codon 72 polymorphism has been investigated as a risk factor for cancer in different populations; however, the results have been inconsistent. This study investigated the risk of developing gastric or colorectal cancer associated with the p53 codon 72 polymorphism in a Korean population. METHODS We conducted a large-scale(More)
AIM Sharing clinical information across care settings is a cornerstone to providing quality care to older people with complex conditions. The purpose of the present study was to examine the reliability of the interRAI Long Term Care Facilities (interRAI LTCF) and the interRAI Home Care (interRAI HC), comprehensive and integrated assessment instruments with(More)
PURPOSE S-1 is a fourth-generation oral fluoropyrimidine that was developed to mimic the effects achieved with protracted continuous infusion of 5-fluorouracil (5-FU). This phase II study evaluated the efficacy and safety of S-1 salvage chemotherapy in patients with paclitaxel- and cisplatin-refractory gastric cancer. The primary end point was(More)
BACKGROUND Imatinib mesylate has been used for the treatment of unresectable or metastatic gastrointestinal stromal tumors (GIST). The current recommended dose of imatinib is 400 mg/day that is increased to 800 mg/day in cases with disease progression. However, imatinib can be associated with diverse adverse events, which has limited its use. We report a(More)
Cancers of an unknown primary site are heterogenous with respect to their clinical and pathologic features. They are generally very aggressive, but specific favorable subsets have a better prognosis. For these favorable subsets, taxane based chemotherapy is very effective for a subset of woman with papillary serous peritoneal adenocarcinoma. A 52 year-old(More)
