Evaluation of design parameters on the outcome of intrastromal ring surgery using biomechanical simulations
<p><strong><a title="Evaluation of design parameters on the outcome of intrastromal ring surgery using biomechanical simulations" href="../records/13377029?preview=1&token=eyJhbGciOiJIUzUxMiJ9.eyJpZCI6IjUzYjY5ZWY4LTgzZTctNDUyMi05MDkxLTJjZjBlMWMxMzYxOCIsImRhdGEiOnt9LCJyYW5kb20iOiI4MmRhMThhNjlkZGE4NTg5OWQ1MDRlZWYxNjIwZmU3MCJ9.DuFue1sYgSBRo9k0tqSJKkh3gKyZaIbvn0i4MupXLei0aBMYdhYX05ZPjMhDdn6ufu0M4tgxRkmNbxdQkwzI4A">10.5281/zenodo.13377029 </a>Background</strong>: The cornea plays a role in the refractive power of the eye, and when its natural curvature and thickness are compromised by diseases such as keratoconus or high myopia, this results in loss of visual acuity. Intracorneal rings (ICRs) were developed as a treatment option to restore the natural corneal curvature by implanting rings into tunnels cut within the corneal stroma. However, selecting and placing the appropriate ring can be difficult, and predicting refractive outcomes is challenging.</p> <p><strong>Objective</strong>: The purpose of this study was to better understand the design parameters of the rings that determine postoperative refractive and mechanical outcomes.</p> <p><strong>Methods</strong>: We developed an automated finite element simulation pipeline for ICR implantation and tested 300 variations of 20 ICRs.</p> <p><strong>Results</strong>: The outcome of ICR was dominated by the vertical size of the ring; 84% of the change in corneal curvature can be attributed to the vertical size of the ring, while only 13% were attributed to the detailed cross-sectional shape of the ring. However, the cross-sectional shape of the ring is limited to the change in axial length and contact pressure between the ring and the cornea. The horizontal dimension of the ring plays only a minor role in the postoperative outcome.</p> <p><strong>Conclusion</strong>: These results support Keraring's approach to ring scaling, in which only the vertical dimension of the ring is changed, while the horizontal dimension remains constant. Numerical models help to understand ICR outcomes, design implants, and personalize empirical nomograms to achieve more successful postoperative outcomes.</p>

One scaffold, two conformations: The ring-flip of the messenger InsP8 occurs under cytosolic conditions
<p>Inositol poly- and pyrophosphates (InsPs and PP-InsPs) are central eukaryotic messengers. These very highly phosphorylated molecules can exist in two distinct conformations, a canonical one with five phosphoryl groups in equatorial positions, and a “flipped” axial conformation. Using <sup>13</sup>C-labeled InsPs / PP-InsPs, the behavior of these molecules was investigated by 2D-NMR under solution conditions reminiscent of a cytosolic environment. Remarkably, the most highly phosphorylated messenger InsP<sub>8</sub> readily adopts both conformations at physiological conditions. Environmental factors - such as pH, metal cation composition, and temperature - strongly influence the conformational equilibrium. Thermodynamic data revealed that the transition of InsP<sub>8</sub> from the equatorial to the axial conformation is, in fact, an exothermic process. The speciation of InsPs and PP-InsPs also affects their interaction with protein binding partners; addition of Mg<sup>2+</sup> decreased the binding constant K<sub>d</sub> of InsP<sub>8</sub> to an SPX protein domain. The results illustrate that PP-InsP speciation reacts very sensitively to solution conditions, suggesting it might act as an environment-dependent molecular switch.</p>
