Lithosiini genera of the Asura / Miltochrista generic complex related to Barsine Walker, 1854 sensu lato and Asura Walker, 1854 are overviewed. Barsine is considered to be a group having such an autapomorphic feature as a basal saccular process of valva only. Many species without this process are separated to the diverse and species-rich genus Ammatho stat. nov., which is subdivided here into eight subgenera including Idopterum Hampson, 1894 downgraded here to a subgenus level, and six new subgenera: Ammathella Volynkin, subgen. nov., Composine Volynkin, subgen. nov., Striatella Volynkin & Huang, subgen. nov., Conicornuta Volynkin, subgen. nov., Delineatia Volynkin & Huang, subgen. nov. and Rugosine Volynkin, subgen. nov. A number of groups of species considered previously by various authors as members of Barsine are erected here to 20 new genera and four subgenera: Ovipennis (Barsipennis) Volynkin, subgen. nov., Ovipennis (Coccinigripennis) Volynkin & Huang, subgen. nov., Barsura (Tenebrasura) Volynkin, subgen. nov., Argentosine Volynkin, gen. nov., Esmasura Volynkin & Huang, gen. nov., Matsumursine Volynkin & Huang, gen. nov., Floridasura Volynkin, gen. nov., Fossia Volynkin, Ivanova & Huang, gen. nov., Wittasura Volynkin, gen. nov., Disparsine Volynkin, gen. nov., Moorasura Volynkin & Huang, gen. nov., Sarbine Volynkin, gen. nov., Sarbine (Processine) Volynkin, subgen. nov., Hampsonascia Volynkin, gen. nov., Cernysura Volynkin, gen. nov., Barsilene Volynkin & Huang, gen. nov., Nanarsine Volynkin, gen. nov., Amphisine Volynkin, gen. nov., Karolia Volynkin, gen. nov., Niveutane Volynkin, gen. nov., Rubrindiania Volynkin & Huang, gen. nov., Barsaurea Volynkin & Huang, gen. nov., Integrivalvia Volynkin & Huang, gen. nov. and Aberrasine Volynkin & Huang, gen. nov. The genus Nebulene Volynkin & Černý is downgraded to a subspecies of Ovipennis. The genus Eutane Walker, 1854 is downgraded to a subspecies of Asura. The genera Miltasura Roepke, 1946 and Gymnasura Hampson, 1900 are synonymised here with Cyme Felder, 1861 and Asura respectively. The genera Asuropsis Matsumura, 1927, Neasuroides Matsumura, 1927 and Asuridoides Daniel, 1951 are synonymised with Miltochrista Hübner, [1819]. The genus Allochrista Roepke, 1946 is synonymised with the subgenus Thyrgorina Walker, [1865] of the genus Lemyra Walker, 1856 (tribe Arctiini) with establishing a new combination Lemyra (Thyrgorina) toxopei (Roepke, 1946), comb. nov. Other six new synonyms are established: Barsine pardalis (Mell, 1922) = Barsine miranda Kishida & Wang, 2017, syn. nov., Barsine striata striata (Bremer & Grey, 1852) = Miltochrista quelparta Okamota, 1924, syn. nov., Floridasura tricolor (Wileman, 1910) = Barsine coccinea Moore, 1886, syn. nov., Disasuridia metaphaea (Hampson, 1900) = Disasuridia flava Fang, 1991, syn. nov., Aberrasine aberrans aberrans (Butler, 1877) = Miltochrista decussata (Moore, 1877), syn. nov. and Cabarda nigripuncta (Wileman & South, 1919) = Asura lunilinea Schaus, 1922, syn. nov. In addition, it is stated that Miltochrista quadrifasciata Rothschild, 1913 described from New Guinea and currently belonging to the genus Cyme (a junior synonym of Cyme sexualis (Felder, 1864)) is an invalid name, being a secondary junior homonym (homonym nov.) of Cyme quadrifasciata (Rothschild, 1913), comb. nov. described from Sulawesi. A full check-list of members of the Asura / Miltochrista generic complex with 370 new combinations is present.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus driving the ongoing coronavirus disease 2019 (COVID-19) pandemic, continues to rapidly evolve. Due to the limited efficacy of vaccination in prevention of SARS-CoV-2 transmission and continuous emergence of variants of concern (VOC), orally bioavailable and broadly efficacious antiviral drugs are urgently needed. Previously we showed that the parent nucleoside of remdesivir, GS-441524, possesses potent anti-SARS-CoV-2 activity. Herein, we report that esterification of the 5′-hydroxyl moieties of GS-441524 markedly improved antiviral potency. This 5′-hydroxyl-isobutyryl prodrug, ATV006, demonstrated excellent oral bioavailability in rats and cynomolgus monkeys and exhibited potent antiviral efficacy against different SARS-CoV-2 VOCs in vitro and in three mouse models. Oral administration of ATV006 reduced viral loads and alleviated lung damage when administered prophylactically and therapeutically to K18-hACE2 mice challenged with the Delta variant of SARS-CoV-2. These data indicate that ATV006 represents a promising oral antiviral drug candidate for SARS-CoV-2.

Background In this study, we aim to investigate the awareness of, attitudes toward, and experiences with diagnostic genetic testing among parents of children suspected of having inherited retinal disease (IRDs) in China. Methods Semistructured, face‐to‐face, and in‐depth interviews were carried out with parents of children with suspected IRDs in this qualitative study. Inductive content analysis was used for data processing. Results Forty‐six parents participated in our interviews, and 47.8% of them supported genetic testing for following four main reasons: to help in making informed reproductive health decisions, to prepare for novel potential treatment, to identify the underlying causes of IRDs, and to satisfy curiosity about the heredity of IRDs. Among them, 19.6% were opposed to the testing for four main reasons, namely lack of therapeutic benefit, difficulty in affording the testing cost, doubt in the accuracy of clinical diagnosis, and the presence of concerns about the limitations of genetic testing. 47.8% of the parents expressed concerns that the genetic findings might lead to potential psychological stress. Conclusion In this study, we showed that nearly half of the parents supported genetic testing mainly for family planning, and a fifth of the parents were opposed to the testing mainly for lack of therapeutic benefit. Moreover, half of the parents expressed concern that a positive genetic result may create potential psychological burden to the parents and children.
