mTORC1 Signaling and Negative Lens-Induced Axial Elongation

Investigative Opthalmology & Visual Science, 2023
The mechanism underlying axial elongation during myopia progression remains unknown. Epidermal growth factor receptor (EGFR) signaling is associated with axial elongation. We explored whether mammalian target of rapamycin complex 1 (mTORC1) signaling acts as the downstream pathway of EGFR and participates in negative lens-induced axial elongation ...

Lens-induced myopization and intraocular pressure in young guinea pigs

BMC Ophthalmology, 2020
Background Intraocular pressure (IOP) is an important physiological measure of the eye and is associated with some ocular disorders. We aimed to assess the influence of topical beta blocker-induced IOP reduction on lens-induced axial elongation in young ...

The treatment zone size and its decentration influence axial elongation in children with orthokeratology treatment

BMC Ophthalmology, 2021
Background To investigate whether the treatment zone size (TZS) and treatment zone decentration (TZD) will affect the axial elongation in myopic children undergoing orthokeratology treatment. Methods A self-controlled retrospective study was conducted on

The Effect of Axial Length Elongation on Corneal Biomechanical Property [PDF]

Frontiers in Bioengineering and Biotechnology, 2021
Background: To investigate the correlation between the corneal biomechanical parameter stress-strain index (SSI) and axial length (AL) in moderately elongated eye (MEE) and severely elongated eye (SEE).Methods: This study included 117 eyes from 117 participants. Among them, 59 (50.4%) had MEE (AL<26 mm) and 58 (49.6%) had SEE (AL≥26 mm).

The roles of stress state and pre-straining on Swift effect for an extruded AZ31 Mg alloy

Journal of Magnesium and Alloys, 2023
The Swift effect of Mg alloy is sensitive to initial texture. However, dislocation slip is the main deformation mechanism during torsion of Mg alloy. The underlying relation of Swift effect and dislocation slip is still not clarified.

Vitreous chamber depth as part of axial elongation in pediatric myopia. [PDF]

BMC Ophthalmol
Abstract Background This study explored the connections between axial length (AL) and other ocular parameters, including central corneal thickness (CCT), aqueous chamber depth (AD), lens thickness (LT), and vitreous chamber depth (VCD), during myopia progression in children.

Influence of Overnight Orthokeratology on Axial Elongation in Childhood Myopia [PDF]

Investigative Opthalmology & Visual Science, 2011
This prospective study was conducted to assess the influence of overnight orthokeratology (OK) on axial elongation in children, with those wearing spectacles as controls.One hundred five subjects (210 eyes) were enrolled in the study. The OK group comprised 45 patients (90 eyes, age 12.1 ± 2.5 years, mean ± SD; OK group) who matched the inclusion ...

Tomato EF-Tsmt, a functional mitochondrial translation elongation factor from higher plants [PDF]

, 2003
Ethylene-induced ripening in tomato (Lycopersicon esculentum) resulted in the accumulation of a transcript designated LeEF-Tsmt that encodes a protein with significant homology to bacterial Ts translational elongation factor (EF-Ts).

Axial length change and its relationship with baseline choroidal thickness – a five-year longitudinal study in Danish adolescents: the CCC2000 eye study

BMC Ophthalmology, 2020
Background Myopic eyes are longer than nonmyopic eyes and have thinner choroids. The purpose of present study was to investigate whether a thinner subfoveal choroid at 11 years of age predicted axial eye elongation and myopia during adolescence.
