Transcriptome analysis of medaka spermatogonial stem cell line (SG3) infected with ranaviruses in vitro.

The medaka spermatogonial stem cell line (SG3) is a well-established cell line that can be induced to differentiate into sperm in vitro. Ranavirus, a genus of viruses widely distributed among fish, amphibians, and reptiles, poses a significant threat to these organisms. This study aimed to investigate the morphological changes and transcriptomic responses in SG3 following infection with three ranavirus strains: Andrias davidianus ranavirus (ADRV), Rana grylio virus (RGV), and Siniperca chuatsi ranavirus (SCRaV).

Transcriptome analysis of the spermatogonial stem cell line of Opsariichthys bidens after infection with three strains of ranaviruses.

The long-term-cultured Opsariichthys bidens spermatogonial stem cell line (ObSSC) was established in our previous study, which could be induced to differentiate into sperm in vitro. The genus Ranavirus is a large double-stranded DNA virus with a high degree of pathogenicity, which can be widely transmitted in fish, amphibians and reptiles. It is highly representative and possesses significant research value.

The degree of prevalence of similarity between outer tropical cyclone rainbands and squall lines.

Tropical cyclone rainbands (TCRs) are not only one of the most striking and persistent features of tropical cyclones (TCs) but also one of the major causes for extreme floods as TCs approach or encounter the land area. TCRs have been traditionally considered as manifestations of atmospheric waves initiated near the eyewall or close to the TC center. However, the limited evidence from recent studies showed the possibility for TCRs to develop squall-line-like characteristics in the outer region of TCs.
