The domesticated silkworm (Bombyx mori) was domesticated from wild silkworm (Bombyx mandarina) more than 5,000 years ago. During domestication, body color between B. mandarina and B. mori changed dramatically. However, the molecular mechanism of the silkworm body color transition is not known. In the present study, we examined within- and between-species nucleotide diversity for eight silkworm ...

Due to growing interest in alternative and sustainable high-quality feed sources for the livestock industry, we carried out a study determine optimal inclusion levels of two insect species (Gryllus bimaculatus Bombyx mori) ruminants, as well evaluating their impacts on rumen fermentation characteristics methane production. An experiment was performed using an vitro model 24 h with ruminant diet...

The hemolymph chymotrypsin inhibitor b1 (CIb1) of silkworm, Bombyx mori, plays an important role in innate immunity. In order to study its encoding gene CIb1, five heterogeneous promoter fragments of 844 bp, 682 bp, 516 bp, 312 bp and 82 bp in length were cloned from genomic DNA of the p50 silkworm strain. Characterization of the CIb1 promoter was performed in vitro using the firefly luciferase...

This paper presents for the first time an extended Mori-Tanaka approach aimed at identifying little-explored piezoelectric response of unidirectional nanoporous composites with energetic surfaces. The interface is simulated using generalized Gurtin-Murdoch coherent model considering nonvanishing in-plane surface stress and electric displacement. analytical solutions Eshelby’s inhomogeneity prob...

In insects, chitinases participate in the periodic shedding of old exoskeletons and the turnover of peritrophic membranes. Chitinase family members have been identified in dozens of species, including Tribolium castaneum, Drosophila melanogaster, and Anopheles gambiae. In this study, nine chitinases and three hypothetical chitinases have been identified in Bombyx mori L. (Lepidoptera: Bombycida...

background: in the light of various applications of uv laser in biological system, we have investigated the effect of picosecond uv laser radiation on silkworm bombyx mori. materials and methods: the eggs of nb4d2 of different stages were exposed to pico second pulse laser at 355 nm from nd:yag laser for different durations. results: due to irradiation alterations in crescent larval body markin...

We study the birational properties of hypersurfaces in products of projective spaces. In the case of hypersurfaces in P × P, we describe their nef, movable and effective cones and determine when they are Mori dream spaces. Using this, we give new simple examples of non-Mori dream spaces and analogues of Mumford’s example of a strictly nef line bundle which is not ample.

the present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of bombyx mori l (lepidoptera: bombycidae). the observed parameters significantly increased in all the treated groups when compared with those of the corre...

Purpose: To investigate the potential activity of Bombyx mori and its formulations against isoproterenol (ISO) induced cardiotoxicity. Methods: Wistar rats were orally pretreated with the ethanol extract of Bombyx mori cocoons in two doses (250 and 500 mg/kg) for 30 days; rats were similarly pretreated with its polyherbal formulations incorporating Khamira Abresham sada (KAS) and Khamira Abresh...
