This paper addresses the impact of investment in information technology (IT) on the recent resurgence of world economic growth. We describe the growth of the world economy, seven regions and 14 major economies during the period 1989–2003. We allocate the growth of world output between input growth and productivity and find, surprisingly, that input growth(More)
A hepatocellular carcinoma cell line, LMH, has been established from a hepatocellular carcinoma induced in a male leghorn chicken by diethylnitrosamine. The cell line is characterized by well-differentiated morphological and biochemical features including the expression of glucose-6-phosphatase and canalicular ATPase activities and triploid karyotype with(More)
Saccharomyces cerevisiae S-II was purified to near homogeneity as a protein stimulating RNA polymerase II. Four of seven lysyl endopeptidase-digested fragments of S-II were located in the PPR2 sequence reported previously. Analysis of a genomic clone of S-II revealed that S-II and PPR2 are the same protein consisting of 309 amino acid residues, and frame(More)
In this study, we analysed the mitochondrial DNA D-loop region of Japanese native chickens to clarify their phylogenetic relationships, possible maternal origin and routes of introduction into Japan. Seven haplogroups (Types A-G) were identified. Types A-C were observed in Jidori, Shokoku and related breeds. However, Type C was absent in Shokoku, which was(More)
Chicken were possibly domesticated in South and Southeast Asia. They occur ubiquitously in East Africa where they show extensive phenotypic diversity. They appeared in the region relatively late, with the first undisputed evidence of domestic chicken in Sudan, around ~ 700 BC. We reveal through a detailed analysis of mitochondrial DNA D-loop sequence(More)
The incidence of ovarian atypical endometriosis and its association with malignant epithelial tumours in a consecutive series of cases during the period 1987 to 1995 were studied. Atypical glandular changes were observed in four (1.7%) of 255 ovarian endometriosis cases and one patient with ovarian atypical endometriosis developed subsequent endometrioid(More)
Human lung cancer sublines resistant to cisplatin (CDDP) have been developed by continuously exposing cells to gradually increasing doses of CDDP and use of the limiting dilution technique. The cell lines used were PC-7, PC-9 and PC-14 (pulmonary adenocarcinoma) and H69 and N231 (small-cell lung cancer). The resistant phenotype of the resistant sublines was(More)
PURPOSE To evaluate the accuracy and precision of "deep-forehead" temperature with rectal, esophageal, and tympanic membrane temperatures, compared with blood temperature. METHODS We studied 41 ASA physical status 1 or 2 patients undergoing abdominal and thoracic surgery scheduled to require at least three hours. "Deep-forehead" temperature was measured(More)
The authors present the clinical, radiological, and pathological features of a malignant intracerebral nerve sheath tumor that occurred in the right parietooccipital lobe of a 4-year-old girl. Computerized tomography scanning and magnetic resonance imaging demonstrated a 5x5x4-cm multiloculated mass with considerable enhancement of the irregularly shaped(More)
