The shortage of human livers available for hepatocyte isolation limits its clinical application. The availability of cloned, conditionally immortalized hepatocytes that could be grown in culture but would lose their transformed phenotype and provide metabolic support upon transplantation would greatly facilitate the treatment of acute liver failure.

A 58-year-old Japanese male patient visited our hospital for evaluation of an elastic hard mass, measuring 80 x 50 mm, in the right axillary area. Incisional biopsy for suspected malignancy was performed, and histopathologic examination by hematoxylin-eosin (H&E) staining yielded a diagnosis of poorly differentiated adenocarcinoma metastatic from an unknown(More)
We report a rare case of breast hemangioma found in a 70-year-old Japanese female. Before seeking medical attention, the patient noticed a hard mass in her right breast but denied associated symptoms. A mammography revealed a well-circumscribed, highly dense, lobular nodule located in the middle inter portion of the right breast. To verify this finding, we(More)
We retrospectively analyzed the expression of epidermal growth factor receptor (EGFR) as a prognostic marker to predict neoadjuvant chemotherapy response and survival among breast cancer subtypes. We used immunohistochemical profiles to subtype the patients. EGFR expression was determined using immunohistochemistry. All patients received an(More)
Patch-clamp and fluorescence measurements of cytoplasmic Ca(2+) concentration ([Ca(2+)](i)) were performed to directly detect extracellular Ca(2+) entry into cultured parathyroid cells from patients with secondary hyperparathyroidism. Cells loaded with fluo-3 AM or fluo-4 AM showed a transient increase in fluorescence (Ca(2+) transient) following 10 s(More)
BACKGROUND Papillary thyroid carcinoma often has lymph node metastasis, compared with follicular thyroid carcinoma. The study showed that epithelial-mesenchymal transition occurs in carcinoma cells during the first stage of metastasis, where some extracellular matrix molecules are secreted in large quantities. Sialic acid carried by fibronectin as the(More)
Of Luncheon Seminar CLINICAL APPLICATIONS OF RECOMBINANT DRUGS IN REPRODUCTIVE MEDICINE Naoaki KUJI Department of Obstetrics and Gynecology, Keio University, School of Medicine In Japan, several recombinant therapeutic drugs, mostly pituitary gonadotropic hormones, have recently become available for use in the field of reproductive medicine. Although these(More)
BACKGROUND Intracystic abnormalities of the breast may result from debris, intracystic papilloma, or rarely breast cancer. Intracystic tumors cannot be diagnosed based on imaging examinations or fine needle aspiration alone, and therefore excisional biopsy must be performed. We have treated many cases who had nipple discharge with mammary ductoscopy since(More)
