A fraction of the ribosomal 28S genes in some insects are interrupted at specific sites by insertion elements R1 and R2 (also called Type I and II). These elements contain long open-reading frames with homology to reverse transcriptase. We have identified in the silkmoth, Bombyx mori, copies of these elements which have inserted into sites outside the ribosomal DNA (rDNA) units. The 3' ends of ...

In order to improve the stiff and brittle characteristics of pure Bombyx mori (B. mori) silk fibroin (SF) film in the dry state, glycerin (Glyc) has been used as a plasticizer. However, there have been very limited studies on the structural characterization of the Glyc-blended SF film. In this study, (13)C Cross Polarization/Magic Angle Spinning nuclear magnetic resonance (CP/MAS NMR) was used ...

For linearly elastic heterogeneous solids, averaging theorems are developed by Nemat-Nasser and Hori (S. Nemat-Nasser, M. Hori, Micromechanics: Overall Properties of Heterogeneous Solids, Elsevier, Amsterdam, 1993; and S. Nemat-Nasser, M. Hori, J. Eng. Mater. Technol. 117 (1995) 412), using a multi-inclusion model. This model is based on the observation that the average strain and stress in any...

Hemolymph is the circulating fluid of insects and is a key component of their immune system. However, little is known concerning hemocyte identification, development, differentiation and related cellular immune responses. The present study aimed to determine whether a hemocyte extract prepared from Bombyx mori larvae had anti‑inflammatory effects; THP‑1 (a human monocytic leukemia cell line) ce...

Aims: To compare the vitamin D status of 34 children, 9–24 months old, living in an area of Delhi renowned for high levels of atmospheric pollution (Mori Gate), with a comparable age matched group of children from a less polluted (Gurgaon) area of the city. Methods: Serum concentrations of calcium, alkaline phosphatase (ALP), parathyroid hormone (PTH), 25-hydroxyvitamin D (25(OH)D), and 1,25-di...

ylesterase activity. B. mori JHE was sensitiye to 3-octylthio-1,1,1-trifluoro-2-propanone (OTFP), which was developed as a selective inhibitor for lepidopteran JHE, and relatively insensitive to diisopropyl fluorophosphate (DFP), an inhibitor of serine esterases but not of all JHEs. AMRity purification with a trifluoromethyl ketone ligand was more eMc;ent for purMcation of B. mori JHE than DEAE...

Abnormalities in the circadian clock system are known to affect the body's metabolic functions, though the molecular mechanisms responsible remain uncertain. In this study, we achieved continuous knockdown of B. mori Period (BmPer) gene expression in the B. mori ovary cell line (BmN), and generated a Per-KD B. mori model with developmental disorders including small individual cells and slow gro...

Decay and rot are established motifs in art history. They address transience disgust, as well contemplation, devotion humility through the tradition of Memento Mori. In contrast to pure motific depictions decay, Finnish artist Toni R. Toivonen (*1987) arranges deceased animals creates works, which organic components such fur, muscles, flesh blood decompose until dissolution. Organic decompositi...
