This paper provides descriptions of two new theridiosomatid species, and , from the Ryukyu Islands, southwest Japan, with photographs and illustrations of both sexes. is a troglophilic genus composed of two species, (Iriomote Island, Japan) and (Zhu, Zhang & Chen, 2001), (southern China). Miller, Griswold & Yin, 2009, which recently joined the Japanese fauna, was morphologically reexamined based on specimens from the Ryukyus, and taxonomic features of males were reassessed. A distributional map of theridiosomatid spiders in the Ryukyus is also provided, including Suzuki, Serita & Hiramatsu, 2020, and Suzuki, Serita & Hiramatsu, 2020 with their habitat types, web morphology, and web-building behavior in detail.

The correct delineation of tick species is critical for efforts aimed at safeguarding One Health. Historically, the Asian turtle tick (Amblyomma geoemydae sensu lato) has been regarded as a geographically widespread species across much of Asia. However, based on morphological and phylogenomic data, the subtropical lineage (from Japan, Taiwan, and parts of China) of A.

Nrf2 plays a critical role in regulating cytoprotective transcriptional responses and glucose metabolism while also preventing inflammation-induced carcinogenesis. However, Nrf2 can paradoxically promote carcinogenesis. Here, we aimed to elucidate the role of Nrf2 in ATL associated with HTLV-1.
