The effect of low and high concentrations of halothane, enflurane, and isoflurane on posttraining memory function was studied in male ddN mice. Mice were trained to escape an aversive electric foot shock as an unconditioned stimulus within 3 s after being exposed to light and a buzzer as a conditioned stimulus. Immediately after training (first session: 30(More)
Focal adhesion kinase (FAK) is often up-regulated in a variety of malignancies, including gastrointestinal stromal tumor (GIST), and its overexpression seems to be associated with tumor progressiveness and poor prognosis. GIST is well known to have a mutation to c-KIT; thus, a specific c-KIT inhibitor (imatinib) is recognized as the first-line chemotherapy(More)
We report seven early gastric cancers in five patients, which arose in the reconstructed gastric tube after radical resection for esophageal cancer. Four of them occurred in the middle gastric tube and three in the distal gastric tube. Three of 5 cases were reconstructed via the retromediastinal route and two via the presternal route. They all were(More)
AIMS We evaluated the techniques of colonic interposition and supercharge for esophageal reconstruction and discussed the main considerations related to these procedures. PATIENTS AND METHODS In this study, we performed 51 esophageal reconstructions using colonic interposition. Twenty-eight of the 51 patients had synchronous or allochronic gastric(More)
Degradation of basement membrane and extracellular matrix structures are important features of the metastatic process of malignant tumors. Human heparanase degrades heparan sulfate proteoglycans, which represent the main components of basement membranes and the extracellular matrix. Because of the role of heparanase in tumor invasion and metastasis, we(More)
PURPOSE To evaluate retrospectively outcomes after radiofrequency (RF) ablation for pulmonary metastases from esophageal cancer. MATERIALS AND METHODS This study included 21 consecutive patients who met inclusion criteria (all men; mean age, 66.0 y) and had pulmonary metastases from esophageal cancer. There were 31 tumors (mean size, 1.7 cm) that were(More)
Overexpression of ING1, a candidate tumor suppressor gene, efficiently blocks cell growth or induces apoptosis in different experimental systems. ING1 maps to chromosome 13q33-34, and because loss of the terminal region of chromosome 13q has been implicated in esophageal squamous cell cancer (ESCC), we examined ESCC for genetic alterations of ING1. Among 31(More)
Taxanes are approved for the treatment of breast cancer that has spread to the lymph nodes, following surgery and doxorubicin containing chemotherapy. Taxanes have improved the survival of breast cancer patients, especially in estrogen receptor (ER) negative population in clinical settings. This time we examined the relationship between chemosensitivity to(More)
BACKGROUND Oesophageal squamous cell carcinoma (OSCC) often arises from preceding dysplastic lesions in the oesophageal epithelium. However, the molecular changes occurring in premalignant lesions are not well understood. An epigenetic change is an example of OSCC that may occur within the epithelium. AIM To investigate the methylation status of multiple(More)
