Cytogenetic Study of Rat Cell Lines Transformed by DNA Fragments of Human Adenovirus Types 12 and 7

A cytogenetic study of a rat normal cell line, 3Y1-B clone 1-6 (3Y1) and its adenovirus (Ad) transformed derivatives, W4 (tranformed by Ad12 virion), CY1-1 (transformed by Ad12 DNA EcoRI-C fragment, left 16.5%), GY1-1 (transformed by Ad12 DNA HindIII-G fragment, left 6.8), HY1 (transformed by Ad12 DNA AccI-K fragment, left 4.7%) and 7IJY1-2 (transformed by Ad7 DNA HindIII-IJ fragment, left 8.1%) was presented. The results obtained are as follows: 1) 3Y1 and some of the transformed cell lines (W4 and GY1-1) were diploid or pseudodiploid, while others (CY1-1, HY 1 and 7IJY-2) were hypotetraploid. 2) The metacentric marker M1 was detected in GY1-1 cells and another metacentric marker, M2, was detected in W4, CY1-1 and 7IJY1-2 cells at a high frequency. By using the Giemsa banding technique, both metacentric markers found in these complete transformants were identified as isochromosomes of the long arm of No. 1 (M1) and the long arm of No. 3 chromosomes (M2), respectively. On the other hand, these markers were detected only at a low frequency in incompletely transformed HY1 cells. 3) Hypersomy of No. 1 or of the long arm of No. 1 chromosome was found in GY1-1 cells, while hypersomy of No. 3 or the long arm of No. 3 chromosome was detected in W4 and CY1-1 cells at a high frequency.departmental bulletin pape

外国につながりのある小学校児童の現状と家庭科の課題<教育科学>

The number of students who require Japanese language instruction has been growing nowadays. The purpose of this research was to clarify how home economics can serve for students with non-Japanese cultural backgrounds or heritage and to create supporting data to develop concrete education assistance. This research focused on the elementary school education as the first mandatory education. Tokyo, Aichi, Kanagawa, Chiba and Saitama were selected as prefectures with the most students with non-Japanese cultural backgrounds or heritage in Japan. Further, this research took the cases of the elementary schools where they had unique efforts to support those students and interviewed the teachers who had taught home economics. As results, several helpful hints were found. They were based on flexible instruction of each school in terms of Japanese instruction as the second language, home economics classes, and cultural exchange. Learning from the hints, it is considered that home economics can undertake the following three actions; collaboration with language learning activities, assessing those students’ comprehensive competency including hands-on activities in home economics, and offering educational moments where each student can respect his/her own culture comparing with other cultures.textapplication/pdfdepartmental bulletin pape

Time-Dependent CP-Violating Asymmetry in B^0→p^0γ Decays

We report the first measurement of CP-violation parameters in B^0 → p^0γ decays based on a data sample of 657×10^6B\bar{B} pairs collected with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We obtain the time-dependent and direct CP-violating parameters, S_p0γ=-0.83±0.65(stat)±0.18(syst) and A_poγ= -0.44±0.49(stat)±0.14(syst), respectively.journal articl
