Absfract: Snake-like robots have good properties ro move on rough rerrain. Their lowheight bodies and articulated structures are proper to go into narrow space and to climb ovei obstacles. nus , manv applications of articulated nzobile robots are expected (e.g. rescue robots). One of the “pes of snake-like robots named ‘Genbu’ consists of active wheels and(More)
BACKGROUND Although patients with recurrent diseases have a very poor prognosis, appropriate pretreatment classification for management of recurrent esophageal cancers has yet to be identified. The patterns of recurrence following radial esophagectomy were retrospectively assessed, and evaluated for possible adaptation as a novel classification of recurrent(More)
The purpose of the present study was to assess the contribution of simultaneous functional/anatomical imaging using integrated 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT), compared with PET alone for the evaluation of initial lymph node staging in esophageal cancer. We studied 167 consecutive patients with thoracic(More)
BACKGROUND The purpose of the current study was to assess whether [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) provides incremental value (e.g., additional information on lymph node involvement or the presence of distant metastases) compared with computed tomography (CT) in patients with esophageal carcinoma. METHODS The authors examined(More)
BACKGROUND Intensive care unit (ICU) psychosis is still a relatively frequent complication after esophageal surgery. We investigated the correlation between ICU psychosis and serum melatonin concentration during the period after esophagectomy. METHODS The study group comprised 41 patients who underwent esophagectomy for treatment of esophageal cancer(More)
Esophageal carcinoma is one of the most lethal tumors, and identification of prognostic factors for patients with this disease is important. Propyl isomerase Pin1 is overexpressed in some human cancers and thought to be an important regulator of cyclinD1. However, the relationships between Pin1 expression and clinicopathologic features in patients with(More)
BACKGROUND Serum p53 antibodies (p53-Ab) have been detected in some cancers. The possible correlation between serum p53-Ab levels in drainage blood from the azygos vein in patients with esophageal carcinoma and prognosis was investigated. MATERIALS AND METHODS Serum p53-Ab levels were examined in both the peripheral and azygos veins of 57 patients, and in(More)
OBJECTIVE Several studies reported that the levels of proinflammatory cytokines such as TNF-alpha, IL-1beta, IL-6, and IL-8 are elevated in the cerebrospinal fluid (CSF) of patients after subarachnoid hemorrhage (SAH). Cytokines in CSF may contribute to the development of vasospasm and cerebral ischemia. In the present study, we investigated the possible(More)
We investigated the possibility of shortening the interval between courses of the commonly prescribed 28-day MVP (mitomycin C, vindesine, and cisplatin) regimen in patients with non-small-cell lung cancer (NSCLC). We conducted a nonrandomized phase II study using recombinant human granulocyte colony-stimulating factor (G-CSF, Chugai) to explore the(More)
Esophageal cancer is a common malignancy with a striking variation in geographical distribution; a reflection of exposure to specific environmental factors, which are still poorly defined. We discuss the recent progress made in the investigation of the molecular biology of esophageal cancer, addressing the topics of genetic alterations, methylation,(More)
