Diversity and phylogeography of Northeast Asian brown frogs allied to Rana dybowskii (Anura, Ranidae).
Yang BT, Zhou Y, Min MS, Matsui M, Dong BJ, Li PP, Fong JJ. Yang BT, et al. Mol Phylogenet Evol. 2017 Jul;112:148-157. doi: 10.1016/j.ympev.2017.04.026. Epub 2017 May 2. Mol Phylogenet Evol. 2017. PMID: 28476494
We investigated the species diversity and phylogeography of the Northeast Asian brown frogs allied to Rana dybowskii (the R. dybowskii species complex: R. dybowskii, R. pirica, and R. uenoi) using four mitochondrial and three nuclear loci. Phylogenetic analyses confirmed t …

Expressions of IL-6, TNF-alpha and NF-kappaB in the skin of Chinese brown frog (Rana dybowskii).
Xi L, Wang C, Chen P, Yang Q, Hu R, Zhang H, Weng Q, Xu M. Xi L, et al. Eur J Histochem. 2017 Oct 19;61(4):2834. doi: 10.4081/ejh.2017.2834. Eur J Histochem. 2017. PMID: 29313598 Free PMC article.
In this study, we investigated the localizations and expression levels of IL-6, TNF-alpha and NF-kappaB in the skin of Rana dybowskii during the breeding period and pre-hibernation. Histologically, the skin of Rana dybowskii consisted of epidermis and dermis. ...The …
