ProTides for Antiviral Activity Beyond Liver Cells
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.

RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.

Background The Flaviviridae virus family includes major human and animal pathogens. The RNA dependent RNA polymerase (RdRp) plays a central role in the replication process, and thus is a validated target for antiviral drugs.

The structure of a dimeric form of SARS-CoV-2 polymerase
Jochheim et al report an alternative, dimeric form of the coronavirus SARS-CoV-2 RNA dependent RNA polymerase (RdRp), which is used to replicate and transcribe its genome.

Iflaviruses in arthropods: when small is mighty
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Molecular studies on the sweet potato virus disease and its two causal agents [PDF]
The studies presented in this thesis contribute to an increased understanding of the molecular aspects, variability and interaction of the two most important viral pathogens of sweet potato (Ipomoea batatas L): Sweet potato feathery mottle virus (SPFMV ...

Template-directed biopolymerization: tape-copying Turing machines
DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear ...

Rituximab-Containing Treatment Regimens May Imply a Long-Term Risk for Difficult-To-Treat Chronic Hepatitis E [PDF]
Hepatitis E virus (HEV) infection is an emerging disease in industrialized countries which is usually characterized by a self-limited course. However, there is an increased risk of HEV persistence in immunocompromised risk populations, comprising ...

Spatial Perturbations within an RNA Promoter Specifically Recognized by a Viral RNA-Dependent RNA Polymerase (RdRp) Reveal That RdRp Can Adjust Its Promoter Binding Sites [PDF]
ABSTRACT RNA synthesis during viral replication requires specific recognition of RNA promoters by the viral RNA-dependent RNA polymerase (RdRp). Four nucleotides (−17, −14, −13, and −11) within the brome mosaic virus (BMV) subgenomic core promoter are required for RNA synthesis by the BMV RdRp (R. W. Siegel et al., Proc. Natl. Acad. Sci.
