DNA Data Bank of Japan (DDBJ) (http://www.ddbj.nig.ac.jp) collected and released 2 368 110 entries or 1 415 106 598 bases in the period from July 2007 to June 2008. The releases in this period include genome scale data of Bombyx mori, Oryzas latipes, Drosophila and Lotus japonicus. In addition, from this year we collected and released trace archive data in collaboration with National Center for...
Toxicity and temporal changes in toxicity of freshwater-marsh-microcosms containing South Louisiana Crude (SLC) or diesel fuel and treated with a cleaner or dispersant, were investigated using Chironomus tentans, Daphnia pulex, and Oryzias latipes. Bioassays used microcosm water (for D. pulex and O. latipes) or soil slurry (for C. tentans) taken 1,7, 31, and 186 days after treatment. SLC was le...
Tol2 is a transposable element of the terminal-inverted-repeat class, residing in the genome of the medaka fish Oryzias latipes. The genus Oryzias contains more than 10 species for which phylogenetic relationships have previously been estimated. To infer the history of Tol2 in this genus we performed genomic Southern blots and PCR analyses of 10 of the species. It was revealed that Tol2 occurs ...
During the breeding season extending from spring to summer, the ovaries of the fish, Oryzias latipes, contain hundreds of follicles, each with an egg at various stages of maturation. Usually, five to fifty eggs are laid by a single female almost every morning(Egami, 1954c). On the other hand, ovaries are small and inactive in winter months. The present author has already reported that small win...
While the commercialization of single-walled carbon nanotubes (SWCNTs) is rapidly expanding, the environmental impact of this nanomaterial is not well understood. Therefore, the present study evaluates the acute aquatic toxicity of SWCNTs towards two freshwater microalgae (Raphidocelis subcapitata and Chlorella vulgaris), a microcrustacean (Daphnia magna), and a fish (Oryzias latipes) based on ...
This introductory review briefly describes the history of medaka as a research organism and the previous accomplishments of the medaka field. The medaka genome project currently underway through the efforts of an international consortium, the Medaka Genome Initiative, and the future prospects for medaka research, particularly for genomic analyses, are also discussed.
Background
بر اساس بررسی‌های انجام شده، بیش از 12 گونه زنبور به صورت پارازیتویید اولیه و یا ثانویه روی پروانه چوبخوار پسته Kermania pistaciella Amsel (Lep.: Tineidae: Hieroxestinae) در باغ‌های پسته استان کرمان زندگی می‌کنند. پنج گونه از آن‌ها قبلاً معرفی شده است.(Achterberg & Mehrnejad, 2002; The braconid parasitoids of Kermania pistaciella (Amsel in Iran, Zoologische Mededelingen Leiden. در این گزارش 7 گو...
In the present paper comparative study of morpho-histology of ovaries of both WT (HdrR) and P53 (-/-) of medaka (Oryzias latipes) has been done. The ovaries of adult are paired and oval-rounded in shape and are situated ventrolaterally. Histologically the ovaries consist of follicles with various stages of development, such as primodial follicle, large follicle and growing follicle. Also, the o...
