Chiral Nanoparticles Suppress Inflammatory Infiltration to Promote Extracellular Matrix Remodeling for Ectopia Lentis Therapy

Advanced Science, EarlyView.
L‐cysteine‐configured chiral polyurethane nanoparticles suppress ocular inflammation and reduce extracellular matrix (ECM) degradation in ectopia lentis by regulating macrophages polarization and inhibiting nuclear factor kappa B signaling pathway. By promoting zonular fiber‐associated protein restoration and tissue repair, this minimally invasive ...

LRG1 Drives Pathological Angiogenesis by Disrupting Neutrophil Mitochondrial Homeostasis in Bladder Cancer

Advanced Science, Volume 13, Issue 56, 9 October 2026.
In bladder cancer, LRG1 binds to ANXA2 to trigger mitochondrial ROS‐dependent NETosis. This pathogenic cascade actively uncouples endothelial‐mural cell interactions, driving profound vascular destabilization. Consequently, targeting the LRG1‐ANXA2 axis attenuates the neutrophil burden and induces structural vascular normalization, offering a powerful ...

Corneal maps and anterior segment tomography of young mixed breed cats [PDF]

Ciência Rural
: This research described corneal maps and anterior-segment tomographic images of young mixed breed cats and compared them to those described in humans. The exams of 13 mixed-breed cats (25 eyes) aged between 18 and 48 months were analyzed. The following

Analyzing contact lens induced changes of the corneal curvature [PDF]

, 1970
Contact lens wear generally induces changes of corneal curvature as measured with the keratometer. Previous studies have considered only one dimension of the curvature change or the fir of the lens.

Anterior Corneal Curvature and Aberration Changes After Scleral Lens Wear in Keratoconus Patients With and Without Ring Segments

, 2019
Objective: To evaluate changes in the anterior corneal curvature and aberrometry after scleral contact lens wear in keratoconus (KC) subjects with and without intracorneal ring segments (ICRS). Methods: Twenty-six subjects diagnosed with keratoconus were

Changes in corneal curvature after wearing the orthokeratology lens [PDF]

, 2013
IntroductionThe orthokeratology lens (OK lens) is designed to reshape the cornea and correct refraction error. Owing to the convenience of ceasing the use of glasses during the day, the use of the OK lens is increasing in myopic children.

The effects of spherical and aspheric rigid gas permeable contact lens: Corneal curvature and topography changes

, 1995
The purpose of this study was to evaluate the performance of a rigid, posterior surface aspheric contact lens compared with a spherical contact lens. A total of 13 subjects were fitted with an aspheric lens in one eye and a spherical lens in the other ...
