Nanoscale Buried Interface Control in Silicone Hydrogels Enables a Biointerface Engineering Platform

Advanced Science, EarlyView.
A hydrophilic coating with controllable nanoscale thickness is applied to commercial silicone hydrogel contact lenses. By combining comprehensive multi‐modal three‐dimensional characterization with an advanced algorithm, the thickness and chemical information of these multilayered structures are resolved.

Modulation of Presynaptic Inhibitory Retinal Circuits for Retinal Ganglion Cell Neuroprotection in Glaucoma

Advanced Science, EarlyView.
Ocular hypertension induces early hyperactivity in inner retinal inhibitory circuitry before substantial retinal ganglion cell loss. Sustained pharmacological inhibition of GABAergic/glycinergic neurotransmission and Vgat‐targeted Lin28 expression suppress this hyperactivity and improve RGC survival without reducing intraocular pressure. These findings

AKAP1 Protects Retinal Ganglion Cells and Preserves Vision by Improving Mitochondrial and Synaptic Health in Glaucomatous Neurodegeneration

Advanced Science, EarlyView.
Intravitreal AAV2‐mediated AKAP1 restoration enhances mitochondrial fusion and biogenesis, improves bioenergetic capacity, and preserves mitochondrial integrity in glaucomatous RGCs. AKAP1 stabilizes presynaptic structure, maintaining synaptic protein expression, and limiting complement‐associated neuroinflammation.

THE VARIATION OF INTRAOCULAR PRESSURE IN THE CONTEXT OF ABDOMINAL SURGERY

Journal of Surgical Sciences, 2020
The human body can be envisioned as a high-performance machine that operates on the principle of "gears". As a consequence, any disorder at a certain level might lead to imbalances in other areas, which are sometimes difficult to detect and measure.

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.
