We verified whether telomere length shortens with age in the loggerhead sea turtle (Caretta caretta) by measuring telomere lengths (relative telomere to single copy gene [T/S] ratios) in whole blood and epidermis from 20 captive individuals with a real-time PCR method. There was no significant correlation between age and relative T/S ratios in blood. Although the correlation between age and relative T/S ratios in epidermis was not significant, older turtles had smaller relative T/S ratios in epidermis. It was thus demonstrated that telomere length in epidermis could be a useful age estimator for sea turtles. Relative age information obtained with this simple, rapid, non-invasive technique may help to advance our understanding of the ecology of endangered sea turtles. This is the first publication on age-related changes in telomere length among chelonians.

教大協のフィンランドの教育視察団に参加し、各訪問校で観察したことを中心に、フィンランド教育を「個人主義」「柔軟性」「基準」「自己責任」をサイクルにした文化的背景をもつものとして、学校制度や教育課程を含む公教育全般を分析する。集団主義の文化や国民性をもつ日本の教育との比較も試みる。

Cytopathogenic (cp) bovine viral diarrhea virus (BVDV) strain KS86-1cp was isolated from a cow persistently infected with non-cytopathogenic (ncp) BVDV strain KS86-1ncp after development of mucosal disease by superinfection with cp BVDV strain Nose. cp BVDV strains 799cp and 839cp were also isolated from independent cattle that developed mucosal disease by superinfection with cp BVDV KS86-1cp. In the present study, genetic analysis revealed that the genes of cp BVDV strains 799cp and 839cp were chimeras between the genes of the persisting ncp BVDVs and that of superinfecting KS86-1cp. The genetic recombination that generates 799cp occurred between the identical points in the Npro gene region, whereas genetic recombination that generates 839cp occurred between different points in the Npro gene region. Both 799cp and 839cp were inherited Jiv gene of KS86-1cp strain and envelope protein genes of the persisting viruses. In addition, neutralization test disclosed that antigenicities of 799cp, 839cp, and KS86-1cp were also similar to each persisting virus. These findings indicate that exogenous cp BVDV containing insertion of Jiv gene in the 5 terminal region can induce genetic recombination with the original ncp BVDV at different points in the Npro gene region, and those viruses have high potential to change those antigenicities and pathogenicities by RNA recombination.

Results of terrestrial heat flow measurements in Peru and Ecuador conducted in 1969, are reported. Eight different sites in Peru and one site in Ecuador were visited for underground temperature measurement. However, data from only five metal mines in Peru and the metal exploration site in Ecuador were usable. The geothermal gradient data on four oil fields in Peru and two in Ecuador were referenced. Although high heat flow has been indicated on the continent side of the Andes (the Gasapalca and the Guajone mines and the Ucayali oil field), low geothermal gradients were also found in mines in high Andes (the Raura and Cerro Verde mines). The latter are suspected to be the result of ground water circulation. The highly disturbed cases of the Morococha and San Vicente mines showed almost zero gradient. Much more work is needed to delineate the regional heat flow pattern of the area.

CRIS (Current Research Information Systems) provide researchers, research managers, innovators, and others with a view over the research activity of a domain. IRs (institutional repositories) provide a mechanism for an organisation to showcase through OA (open access) its intellectual property. Increasingly, organizations are mandating that their employed researchers deposit peer-reviewed published material in the IR. Research funders are increasingly mandating that publications be deposited in an open access repository: some mandate a central (or subject-based) repository, some an IR. In parallel, publishers are offering OA but replacing subscription-based access with author (or author institution) payment for publishing. However, many OA repositories have metadata based on DC (Dublin Core) which is inadequate; a CERIF (Common-European Research Information Format) CRIS provides metadata describing publications with formal syntax and declared semantics thus facilitating interoperation or homogeneous access over heterogeneous sources. The formality is essential for research output metrics, which are increasingly being used to determine future funding for research organizations.

Leptospirosis is an emerging disease around the globe. South Andaman Island is an endemic region for leptospirosis. We herein compared the prevalence of leptospires in urban and rural areas of South Andaman Island. The PCR detection and isolation of Leptospira revealed that pathogenic leptospires were prevalent in sewage water and household drainage water in urban areas and in paddy fields, vegetable field water, and stream water in rural areas. These results demonstrate that intermediates are ubiquitously present in the environment and may be responsible for asymptomatic infections, and also provide an insight into disease ecology.

シベリアのカラマツ林を対象として林床面上および林冠上において渦相関法を適用し,下層植生および全生態系からの蒸発散量を計測した。そして,これらの旬積算値の年々差を評価した。その結果,旬蒸発散量の年々差は全生態系で-11.0 mm~9.5 mm,下層植生で-2.4 mm~4.7 mmと見積もられ,この値は月蒸発散量の平均値の20~30%に相当しており,本林分では顕著な旬蒸発散量の年々差が発生することが明らかとなった。この要因を検討するため,Penman-Monteith式の放射項と移流項の年々差との相関を解析したところ,本林分の低い乖離率を反映して,蒸発散量の年々差は移流項の年々差によって説明されることが分かった。そして,移流項の年々差を生じさせる要素としては,飽差の差異とそれに伴う表面コンダクタンスの変化が重要である。

Imidazoline surfactants belong to the category of cationic surfactants. Cationic surfactants are often quaternary nitrogen salts and are widely used both in non aqueous systems and in applications such as textile softeners, dispersants and emulsifiers. In the class of imidazoline compounds there is a presence of a pendant group, an imidazoline head group and a hydrocarbon tail. This paper reviews the imidazoline and its salts as an emerging class of cationic surfactants. It deals with the synthesis, various properties that prove its use in laundry detergent applications like good detergency, resiliency, foaming property, softening property, rewettability, good storage stability and less irritating property. In addition the film forming and corrosion inhibition properties tend them to varied and numerous industrial applications.
