SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

The FEBS Journal, EarlyView.
The SARS‐CoV‐2 nucleocapsid (N) protein facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone. The Omicron BA.5 variant shows reduced chaperone activity compared to the Wuhan wild‐type protein. Although phosphorylation has no effect on wild‐type N, phosphomimetic modification of BA.5 N restores its RNA ...

Overcoming Polyatomic Interferences in Sulfur Isotope Measurement Using MC‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Optimising plasma conditions via the normalised argon index (NAI) reduces polyatomic interferences, allowing accurate sulfur isotope measurement in low‐resolution mode on MC‐ICP‐MS. Low‐resolution mode enhances sensitivity by approximately threefold compared with conventional high‐resolution analysis.

Activation of the Lectin Pathway Drives Persistent Complement Dysregulation in Long COVID

Immunology, EarlyView.
The complement cascade, a series of blood proteins that assists in the recognition and neutralisation of pathogens, either independently or in conjunction with antibodies, is persistently activated in patients with long COVID. We found that blood plasma samples from patients with long COVID contained elevated concentrations of the mannan‐binding lectin‐

Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

Journal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Injecting nerves with radiological contrast as a novel method of studying the peripheral nervous system

Journal of Anatomy, EarlyView.
We present a method of injecting peripheral nerves with radiopaque contrast and subsequent CT scanning that produces excellent 3D models of the nerves, leaving the specimens intact and ready for further analysis (e.g., for micro‐CT or histology). Abstract The peripheral nervous system has been the subject of various studies on topics ranging from the ...
