We performed gene-based comparative FISH mapping between a wild silkmoth, Samia cynthia ssp. with a low number of chromosomes (2n=25-28) and the model species, Bombyx mori (2n=56), in order to identify the genomic components that make up the chromosomes in a low-number karyotype. Mapping of 64 fosmid probes containing orthologs of B. mori genes revealed that the homologues of either two or four...

The domesticated silkworm, Bombyx mori Linn., a lepidopteran molecular model and an important economic insect that are emerging as an ideal molecular genetic resource for solving a broad range of biological problems. The silkworm, B. mori produces massive amount of silk proteins during the final stage of larval development. These proteins are stored in the middle silk gland and they are dischar...

The Bombyx mori decapentaplegic gene is one of the conserved genes in vertebrate and invertebrates. The TGF-β superfamily contains conserved polypeptide growth factors that play important roles in different cellular processes such as proliferation, apoptosis, differentiation and cell-fate determination. The B. mori dpp gene shares genetic homology with hBMPs and Drosophila dpp. Until now, only ...

oral supplementation with potassium bromide (10, 20 and 40 ?g/ml) to fifth instar larvae of csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori resulted in a significant increase in the fat body glycogen in all the treated groups and in all the three races of the silkworm, b. mori. the fat body protein content was increased with 20 and 40 ?g/ml treated groups in csr2 and csr4...

UNLABELLED The National Academy of Agricultural Science (NAAS) has developed a web-based database to provide characterization information in silkworm. The silkworm database has four major function menus: variety searching, characterization viewing, general information and photo gallery. It provides 321 silkworm varieties characterization information for six different regions namely, Korean, Jap...

objective: the study was conducted to evaluate cardioprotective effect of silk cocoon (abresham) bombyx mori (b. mori) on isoprenaline-induced myocardial infarction. this study deals with the cocoons, which is called abresham in the unani system of medicine. it is one of the 64 drugs which avicenna has mentioned in avicenna’s tract on cardiac drugs and used in the treatment of cardiovascular di...

The purpose of this paper is to present a simple micromechanics-based model to estimate the effective thermal conductivity of macroscopically isotropic materials of matrix-inclusion type. The methodology is based on the well-established Mori-Tanaka method for composite media reinforced with ellipsoidal inclusions, extended to account for imperfect thermal contact at the matrix-inclusion interfa...

A size-dependent strain gradient Mori-Tanaka model (SGMT) is developed by applying strain gradient elasticity to the classical Mori-Tanka (M-T) method. The SGMT model is shown to be able to accurately predict the experimentally observed increase in stiffness of a layerby-layer (LBL)-assembled polyurethane-montmorillonite (PU-MTM) nanocomposite with various volume fractions. 3D Finite Element (F...

Thymosins have been highly conserved during evolution. These hormones exist in many animal species and play an essential role in many biological events. However, little is known regarding the physiological function of silkworm Bombyx mori thymosin (BmTHY). In this study, we investigated the expression pattern of BmTHY in a Bombyx mori larval ovarian cell line (BmN) challenged with Bombyx mori n...
