1. The extracellular matrix (ECM) constitutes the basal lamina and the area between follicular cells. Remodelling the ECM is believed to be a key event in follicular development, especially during selection, and plays an important role in cell migration, survival, and steroidogenesis. miR-199-3p is differentially expressed in the goose granulosa layer during follicular selection and is reported to play a primary role in inhibiting cell migration and invasion. Nevertheless, the effect of miR-199-3p on ovarian...

This study aimed to clone the full-length open reading frame (ORF) of goat ANGPTL8 gene sequence, reveal its molecular and expression characteristics, and explore its effect on the differentiation of goat intramuscular preadipocytes. The full-length ORF sequence of goat ANGPTL8 gene was cloned by RT-PCR technology, and bioinformatics analysis was performed by related biological software. RT-qPCR was used to detect the expression of ANGPTL8 mRNA in goat tissues. Further use of RNA interference to study...

In order to effectively inhibit the explosion of titanium powder, this study used the Hartmann tube experimental system and the 20 L explosion tank experimental system to carry out flame propagation and explosion overpressure experiments, respectively, and the effect of NH4H2PO4 on the explosion suppression of titanium powder was studied. The results show that when the addition of NH4H2PO4 powder is 50%, the flame propagation velocity and explosion pressure can be reduced to the minimum,...

Pangolins have gained increasing global attention owing to their public health significance as potential zoonotic hosts since the identification of SARS-CoV-2-related viruses in them. Moreover, these animals could carry other respiratory viruses. In this study, we investigated the virome composition of 16 pangolins that died in 2018 with symptoms of pneumonia using metagenomic approaches. A total of eight whole virus sequences belonging to the Paramyxoviridae or Pneumoviridae families were identified, including one human parainfluenza virus...
