O sm undalin, a glucoside of osm undalactone, isolated from the royal fern, Osmunda japonica, stim ulated the deterren t cell (“R recep tor” cells, associated with deter­ rency) in the medial sensilla styloconica of Bombyx mori. From the dose-response curve, the lower limit of detection was 3 .6 x l0 ~ 53 .6 x l0 “4 m. This is the first re­ port tha t glucoside lactone elicits the impulses from...

Silk from the Bombyx mori silkworm is a protein-based fiber. Bombyx mori silk fibroin (SF) is one of the most important candidates for biomedical porous material based on its superior machinability, biocompatibility, biodegradation, bioresorbability, and so on. In this paper, we have reviewed the key features of SF. Moreover we have focused on the morphous, technical processing, and biocompatib...

We prove the following statement (theorem 2.1). Let V/P be a birationally rigid Gorenstein Mori fibration on del Pezzo surfaces. If a Mori fibration W is birational to V , then either they are isomorphic, or W is non-Gorenstein. The result was obtained during my stay at the Max-Planck-Institut für Mathematik in Bonn. I would like to use this opportunity and thank the Directors and the staff of ...

The fundamental property of Fano varieties with mild singularities is that they have a finite polyhedral Mori cone. Thus, it is very interesting to ask: What we can say about algebraic varieties with a finite polyhedral Mori cone? I give a review of known results. All of them were obtained applying methods which were originated in the theory of discrete groups generated by reflections in hyperb...

Injection inoculation protocols for fruit body formation of Cordyceps militaris (C. militaris) were investigated to improve the incidence of infection in the silkworm species Bombyx mori (B. mori). Injection, with suspensions of C. militaris hyphal bodies into living silkworm pupae, was used to test for fruit body production. Use of Daeseungjam rather than Baegokjam or Keumokjam varieties of B....

A second-generation linkage map was constructed for the silkworm, Bombyx mori, focusing on mapping Bombyx sequences appearing in public nucleotide databases and bacterial artificial chromosome (BAC) contigs. A total of 874 BAC contigs containing 5067 clones (22% of the library) were constructed by PCR-based screening with sequence-tagged sites (STSs) derived from whole-genome shotgun (WGS) sequ...

Female moths of Bombyx mori were artificially inseminated with cryopreserved semen. The fertility of inseminated females varied from 0% to 76.9% depending on the strain. Addition of fresh semen from triploid males, which are infertile but whose semen includes intact apyrene sperm, greatly improved fecundity of cryopreserved semen from normal males. Frozen apyrene sperm from the triploid donors ...
