Ancient DNA, sampled from ten brown bear (Ursus arctos) skulls excavated from a rock shelter site of the Ainu culture at Bihue, central Hokkaido, Japan, was analyzed.

3. Comparison of the Z and W sex chromosomal architectures in elegant crested tinamou (Eudromia elegans) and ostrich (Struthio camelus) and the process of sex chromosome differentiation in palaeognathous birds. - Tsuda, Yayoi; Nishida-Umehara, Chizuko; Ishijima, Junko; Yamada, Kazuhiko; Matsuda, Yoichi
To clarify the process of avian sex chromosome differentiation in palaeognathous birds, we performed molecular and cytogenetic characterization of W chromosome-specific repetitive DNA sequences for elegant crested tinamou (Eudromia elegans, Tinamiformes) and constructed comparative cytogenetic maps of the Z and W chromosomes with nine chicken Z-linked gene homologues for E.

4. A local damage model for anomalous high toughness of double-network gels - Tanaka, Y.
We present a phenomenological model for anomalously high fracture energy of double-network (DN) gels, which consist of a substantially cross-linked polyelectrolyte gel (first network) and of a quite poorly cross-linked neutral polymer (second network) penetrating into the first network (Gong J.

5. Metabolite profiling and assessment of metabolome compartmentation of soybean leaves using non-aqueous fractionation and GC-MS analysis - Benkeblia, Noureddine; Shinano, Takuro; Osaki, Mitsuru
Levels of sugars, organic acids and fatty acids showed greater relative abundances in the vacuole with 50, 55, and 50% of the respective pools.

6. The molecular basis of chromosome orthologies and sex chromosomal differentiation in palaeognathous birds - Nishida-Umehara, Chizuko; Tsuda, Yayoi; Ishijima, Junko; Ando, Junko; Fujiwara, Atushi; Matsuda, Yoichi; Griffin, Darren K.
Palaeognathous birds (Struthioniformes and Tinamiformes) have morphologically conserved karyotypes and less differentiated ZW sex chromosomes.

7. Comparative chromosome painting map between two Ryukyu spiny rat species, Tokudaia osimensis and Tokudaia tokunoshimensis (Muridae, Rodentia) - Nakamura, Taro; Kuroiwa, Asato; Nishida-Umehara, Chizuko; Matsubara, Kazumi; Yamada, Fumio; Matsuda, Yoichi
Ryukyu spiny rats (genus Tokudaia) are indigenous species that are confined to three islands of the Nansei Shoto archipelago, Amami-Oshima, Tokunoshima and Okinawa-jima, Japan.

8. New water supply technology and development of water utility management in Japan - Magara, Yasumoto; Matsui, Yoshihiko; Ohno, Koichi
The Japanese government published “The Water and Sanitation Broad Partnership Initiative (WASABI)” in March 2006.

9. cDNA-based gene mapping and GC3 profiling in the soft-shelled turtle suggest a chromosomal size-dependent GC bias shared by sauropsids - Kuraku, Shigehiro; Ishijima, Junko; Nishida-Umehara, Chizuko; Agata, Kiyokazu; Kuratani, Shigeru; Matsuda, Yoichi
Mammalian and avian genomes comprise several classes of chromosomal segments that vary dramatically in GC-content.

10. A new primer set for sex identification in the genus Sorex (Soricidae, Insectivora) - Matsubara, K.; Ishibashi, Y.; Ohdachi, S.; Matsuda, Y.
In order to develop a new accurate method for sexing in Sorex species (Soricidae, Insectivora), we synthesized a polymerase chain reaction (PCR) primer set to amplify a part of Sry HMG box in the long-clawed shrew, Sorex unguiculatus.

11. Highly conserved linkage homology between birds and turtles: Bird and turtle chromosomes are precise counterparts of each other - Matsuda, Yoichi; Nishida-Umehara, Chizuko; Tarui, Hiroshi; Kuroiwa, Asato; Yamada, Kazuhiko; Isobe, Taku; Ando, Junko; Fujiwara, Atushi; Hirao, Yukako; Nishimura, Osamu; Ishijima, Junko; Hayashi, Akiko; Saito, Toshiyuki; Murakami, Takahiro; Murakami, Yasunori; Kuratani, Shigeru; Agata, Kiyokazu
The karyotypes of birds, turtles and snakes are characterized by two distinct chromosomal components, macrochromosomes and microchromosomes.

Chromosome-specific painting probes of the laboratory mouse were hybridized to chromosomes of seven Apodemus species, A.

13. Identification of chromosome rearrangements between the laboratory mouse (Mus musculus) and the Indian spiny mouse (Mus platythrix) by comparative FISH analysis - Matsubara, Kazumi; Nishida-Umehara, Chizuko; Kuroiwa, Asato; Tsuchiya, Kimiyuki; Matsuda, Yoichi

14. Metabolic alterations proposed by proteome in rice roots grown under low P and high Al concentration under low pH - Fukuda, Takuya; Saito, Akira; Wasaki, Jun; Shinano, Takuro; Osaki, Mitsuru
Growth inhibition caused by acid soils, especially due to P deficiency and Al stress, is a serious problem for crop production.

15. Anti-parallel membrane topology of two components of EbrAB, a multidrug transporter. - Kikukawa, Takashi; Miyauchi, Seiji; Araiso, Tsunehisa; Kamo, Naoki; Nara, Toshifumi
EbrAB is a multidrug-resistance transporter in Bacillus subtilis that belongs to the small multidrug resistance, and requires two polypeptides of both EbrA and EbrB, implying that it functions in the hetero-dimeric state.

16. Modeling carbon and silicon cycling in the equatorial Pacific - Fujii, Masahiko; Chai, Fei
The equatorial Pacific is a region of significant particulate inorganic carbon (PIC) and biogenic silica sedimentation, the majority of which is carried out by coccolithophorids and diatoms.
