Degeneration of the intervertebral disc is an age-related condition. It also accompanies disappearance notochordal cells, which are remnants developmental stages nucleus pulposus (NP). Molecular changes such as extracellular matrix catabolism, cellular phenotype, and glycosaminoglycan loss in NP have been extensively studied. However, one most significant co- posttranslational modifications, gl...

Abstract Starting from an anti-symplectic involution on a K3 surface, one can consider natural Lagrangian subvariety inside the moduli space of sheaves over K3. One also construct Prymian integrable system following construction Markushevich–Tikhomirov, extended by Arbarello–Saccà–Ferretti, Matteini and Sawon–Shen. In this article we address question Sawon, showing that these systems their asso...
