Long non-coding RNAs (lncRNAs) are essential components of innate immunity, maintaining the functionality of immune systems that control virus infection. However, how lncRNAs engage immune responses during influenza A virus (IAV) infection remains unclear. Here, we show that lncRNA USP30-AS1 is up-regulated by infection of multiple different IAV subtypes and is required for tuning inflammatory and antiviral response in IAV infection.

In this work, a multicomponent polymerization (MCP) approach involving bipyrroles, sulfonyl azides, and diynes was developed to afford a library of poly(bipyrrole-sulfonylimide)s (PPSIs) in high yields and molecular weights, which were further modified to form unique sulfur dioxide (SO2) generators. Bipyrroles served as carbon-based nucleophiles to undergo Cu-catalyzed C-C coupling during the MCP. Upon post-MCP modification by transforming the bipyrrole unit to boron dipyrromethene (BODIPY) and the sulfonylimide moiety to sulfonamide, poly(BODIPY-sulfonamide)s (PBSAs) were obtained as potent anticancer therapeutic agents.

Long-standing challenges including notorious side reactions at the Zn anode, low Zn anode utilization, and rapid cathode degradation at low current densities hinder the advancement of aqueous zinc-ion batteries (AZIBs). Inspired by the critical role of capping agents in nanomaterials synthesis and bulk crystal growth, a series of capping agents are employed to demonstrate their applicability in AZIBs. Here, it is shown that the preferential adsorption of capping agents on different Zn crystal planes, coordination between capping agents and Zn ions, and interactions with metal oxide cathodes enable preferred Zn (002) deposition, water-deficient Zn ion solvation structure, and a dynamic cathode-electrolyte interface.

Nanomicro Lett

January 2025

School of Science and Engineering, The Chinese University of Hong Kong, Shenzhen, 518172, People's Republic of China.

Two-dimensional transition metal dichalcogenides (2D TMDCs) have received considerable attention in local strain engineering due to their extraordinary mechanical flexibility, electonic structure, and optical properties. The strain-induced out-of-plane deformations in 2D TMDCs lead to diverse excitonic behaviors and versatile modulations in optical properties, paving the way for the development of advanced quantum technologies, flexible optoelectronic materials, and straintronic devices. Research on local strain engineering on 2D TMDCs has been delved into fabrication techniques, electronic state variations, and quantum optical applications.

Overall water splitting (OWS) to produce hydrogen has attracted large attention in recent years due to its ecological-friendliness and sustainability. However, the efficiency of OWS has been forced by the sluggish kinetics of the four-electron oxygen evolution reaction (OER). The replacement of OER by alternative electrooxidation of small molecules with more thermodynamically favorable potentials may fundamentally break the limitation and achieve hydrogen production with low energy consumption, which may also be accompanied by the production of more value-added chemicals than oxygen or by electrochemical degradation of pollutants.

Background: Early establishment of energy balance related behaviors (EBRBs) may be effective in combating unhealthy lifestyle in preschoolers. Parents are responsible for cultivating preschoolers' EBRBs directly through parenting practices. Although investigating the impact of various parenting practices on preschoolers' EBRBs is crucial to determine which practices should be recommended to parents to help reverse childhood unhealthy lifestyle, it is important to assess whether these effects of parenting practices on preschoolers' EBRBs would be similar across different groups of preschoolers, necessitating research into the moderating effects of demographic characteristics.
