Destabilization damage characteristics and infrared radiation response of coal-rock complexes.

To investigate the characteristics of destabilization damage in coal-rock complexes. Mechanical property tests were conducted on coal, rock, and their complexes. An infrared thermal camera was employed to real-time monitor the infrared (IR) radiation response signals during the destabilization damage process.

AIV polyantigen epitope expressed by recombinant baculovirus induces a systemic immune response in chicken and mouse models.

Background: The protective efficacy of avian influenza virus (AIV) vaccines is unsatisfactory due to the presence of various serotypes generated by genetic reassortment. Thus, immunization with a polyantigen chimeric epitope vaccine may be an effective strategy for protecting poultry from infection with different AIV subtypes.

Methods: Baculovirus has recently emerged as a novel and attractive gene delivery vehicle for animal cells.

Alternative isoforms of BmYki have different transcriptional co-activator activity in the silkworm, Bombyx mori.

Yorki (Yki), a transcriptional co-activator that is a key component of the Hippo pathway, induces the transcription of a number of targets that promote cell proliferation and survival. Bombyx mori Yki3 (BmYki3), with 445 amino acid residues, facilitates cell migration and cell division, and enlarges cultured cell and wing disc size. In this study, cellular localization, transcriptional co-activator activity, cell migration, cell cycle, and cell size were characterized in alternative isoforms of BmYki.

Functional characterization of BmOVOs in silkworm, Bombyx mori.

Background: In our previous study, we identified four isoforms of the Bmovo gene, Bmovo-1, Bmovo-2, Bmovo-3 and Bmovo-4 from the silkworm ovary and verified that ovarian development was regulated by the BmOVO proteins.

Results: To understand the regulatory mechanisms of ovarian development, the regulation of four BmOVO isoforms on the B. mori ovarian tumor (Bmotu) promoter activity was investigated with luciferase reporter assays.

Circular RNA alterations in the Bombyx mori midgut following B. mori nucleopolyhedrovirus infection.

Thus far, no systematic studies have examined circRNA expression profiles in the silkworm following B.mori nucleopolyhedrovirus (BmNPV) infection. To explore the expression patterns of circRNAs in the silkworm midgut following BmNPV infection, circRNAs in normal midguts and BmNPV-infected midguts were analyzed by high-throughput sequencing.
