SARS-CoV-2 S protein disrupts the formation of ISGF3 complex through conserved S2 subunit to antagonize type I interferon response.

Unlabelled: Viral immunosuppression substantially affects the host immune response of infected patients and the protective efficacy of vaccines. Here, we found that the spike (S) protein, the major vaccine antigen of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), strongly suppresses host innate immunity by inhibiting interferon-stimulated gene (ISG) expression through both S1 and S2 subunits. Mechanistically, the S protein inhibited the formation of the classic interferon-stimulated gene factor 3 (ISGF3) complex composed of STAT1, STAT2, and IRF9 by competing with STAT2 for binding to IRF9, thereby impeding the transcription of ISGs.

PTH1R Suppressed Apoptosis of Mesenchymal Progenitors in Mandibular Growth.

Genetic abnormalities of the parathyroid hormone 1 receptor (PTH1R) lead to profound craniomaxillofacial bone and dentition defects on account of inappropriate tissue metabolism and cellular differentiation. The coordinated activity of differentiation and viability in bone cells is indispensable for bone metabolism. Recent research demonstrates mesenchymal progenitors are responsive to PTH1R signaling for osteogenic differentiation, whereas the effect of PTH1R on cellular survival remains incompletely understood.

Impact of general vs. regional anaesthesia on one-year clinical outcomes and healthcare utilisation after lower limb arthroplasty: a retrospective study.

Introduction: General anaesthesia and regional anaesthesia are used for hip and knee arthroplasty but their impact on long-term outcomes remains unclear. This study aimed to compare one-year clinical outcomes and healthcare utilisation in patients receiving general or regional anaesthesia for hip or knee arthroplasty.

Methods: Using data from the TriNetX Global Collaborative Network, we conducted a retrospective analysis of 247,142 patients aged 40-90 y who underwent hip or knee arthroplasty between 2010 and 2023.

The evolution of resource management in Taiwanese fisheries: coastal and offshore perspectives.

This study investigates the historical changes in resource development of offshore and coastal fisheries around Taiwan from 1970 to 2021 using the mean trophic level (MTL) and Fishing-in-Balance (FiB) indices. Utilizing data from the Fisheries Statistical Yearbook, three scenarios were employed to assess the effects of highly migratory, oceanic migratory, and seasonal migratory fish species on the MTL and FiB indices. The analysis revealed a continuous increase in MTL for offshore and coastal fisheries, suggesting shifts in the trophic structure and potential over-exploitation of higher trophic level species.
