Histidine Supplementation Stabilizes Hearing and Vision and Improves Growth in HARS1‐Related Autosomal Recessive Disorder Associated With Usher‐Like Symptoms

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 10, Page 2289-2308, October 2026.
ABSTRACT Autosomal recessive HARS1‐related disorder (originally described as Usher syndrome type 3B) caused by a homozygous Y454S variant in the histidyl‐tRNA synthetase gene (HARS1) is characterized by progressive sensorineural hearing and vision loss and respiratory deterioration with risk for sudden death following febrile illnesses.

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

open access: yesAdvanced Physics Research, Volume 5, Issue 10, October 2026.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Astigmatism impact on visual performance: Meridional and adaptational effects

open access: yes, 2014
PURPOSE: Astigmatic subjects are adapted to their astigmatism and perceptually recalibrate upon its correction. However, the extent to which prior adaptation to astigmatism affects visual performance, whether this effect is axis dependent, and the time ...

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts

open access: yesLaser &Photonics Reviews, Volume 20, Issue 20, 21 October 2026.
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Selective suture cutting for control of astigmatism following cataract surgery

open access: yesIndian Journal of Ophthalmology, 1992
Use of 10-0 monofilament nylon in ECCE cataract surgery leads to high with the rule astigmatism. Many intraoperative and post operative methods have been used to minimise post operative astigmatism.

Understanding higher‐order aberrations in keratoconus

open access: yesOptometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, Volume 7, Issue 5, October 2026.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

‘In silico labelling’: Exploring the biological landscape at the nanoscale using intelligent multimodal optical microscopy

open access: yesJournal of Microscopy, Volume 304, Issue 1, Page 41-50, October 2026.
Abstract Multimodal optical microscopy has recently converged with artificial intelligence (AI) to enable in silico labelling—the computational prediction of fluorescence‐like molecular contrast from label‐free measurements. Fluorescence plays a crucial role in linking microscopy and spectroscopy at molecular level, enabling image formation by means of
