Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.ABSTRACT Type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) frequently coexist, exacerbating disease burden. However, the molecular mechanisms underlying the progression from T2DM to T2DM‐associated NAFLD remain unclear. This study investigated the regulatory function of FOS‐mediated PTGS2 activation in this transition.

One-step error correction for multipartite polarization entanglement
, 2011 We present two economical one-step error-correction protocols for multipartite polarization-entangled systems in a Greenberger-Horne-Zeilinger state. One uses spatial entanglement to correct errors in the polarization entanglement of an N-photon system ...
