BACKGROUND Adaptor proteins, with multimodular structures, can participate in the regulation of various cellular functions. A novel adaptor protein XB130 has been implicated as a substrate and regulator of tyrosine kinase-mediated signaling and in controlling cell proliferation and apoptosis in thyroid and lung cancer cells. However, its expression and role(More)
OBJECTIVE A glycosylated transmembrane protein, CD147, has been implicated in regulating lymphocyte responsiveness and leukocyte recruitment. As lupus nephritis (LN) often follows a relapsing-remitting disease course, accurate understanding of the disease activity would be extremely helpful in improving prognosis. Unfortunately, neither clinical nor(More)
BACKGROUND E2F Transcription Factor 5 Protein (E2F5) is considered to act primarily as a transcriptional repressor in the cell cycle. However, its expression and role in esophageal squamous cell carcinoma (ESCC) have not been investigated. We examined whether the expression of E2F5 is related to the clinicopathological features and prognosis of patients(More)
UNLABELLED BACK GROUND/AIM: The purpose of the present study was to clarify the clinicopathological features of non-hepatitis B and -C (NBNC) hepatocellular carcinoma (HCC), the incidence of which has been increasing. PATIENTS AND METHODS Two hundred and eighty-four patients with HCC were classified into three groups according to viral hepatitis status,(More)
Recent evidence suggests that the targeting of membrane proteins specifically activated in cancer stem cells (CSCs) is an important strategy for cancer therapy. The objectives of the present study were to investigate the expression and activity of ion-transport-related molecules in the CSCs of esophageal squamous cell carcinoma. Cells exhibiting strong(More)
We report successful treatment of stenosis of the portal vein caused by enlargement of the remnant liver after extended right hepatectomy with interventional radiology using an intraportal expandable metallic stent (EMS). A 75-year-old man underwent extended right hepatectomy after percutaneous transhepatic right portal embolization for advanced gallbladder(More)
An 87-year-old man visited our hospital with a chief complaint of melena. Invagination caused by rectal cancer or sigmoid colon cancer was suspected as a result of physical and radiological examinations. Since there were no subjective symptoms, laparoscopic surgery was planned electively. As an operative finding, a tumor was found in the rectosigmoid colon(More)
In recent years, with the increase in the adoption of anus-preserving surgery, understanding of residual lower rectal cancer distribution to the anal side after chemoradiotherapy (CRT) has become an increasingly important issue. We aimed to clarify the pathological safe distal resection margin for lower rectal cancer after preoperative CRT. This study(More)
UNLABELLED We perform preoperative chemoradiotherapy for patients with advanced lower rectal cancer in our department. In April 2012, we started laparoscopic lateral lymph node dissection for preventive dissection in patients without lateral lymph node enlargement on preoperative diagnosis. We compared the short-term results of laparoscopic lateral(More)
BACKGROUND Isolated anatomic total caudate lobectomy is indicated in patients who have liver tumors limited to the caudate lobe. However, isolated caudate lobe resection is a challenging surgical procedure that required safe and reliable techniques. All portal and hepatic veins that connect this area originate from the first branch of the portal vein or(More)
