Dopamine (DA) storage and release are reduced in form deprivation myopia (FDM) in a wide range of species, from chicks to primates. FDM can be prevented by treatment with DA agonists such as apomorphine, and paradoxically by the dopamine neurotoxin 6-hydroxydopamine. In this study, we increased the DA levels by direct intravitreal DA injections to learn if(More)
The formation of tubular nanostructures normally requires layered, anisotropic, or pseudo-layered crystal structures, while inorganic compounds typically do not possess such structures, inorganic nanotubes thus have been a hot topic in the past decade. In this article, we review recent research activities on nanotubes fabrication and focus on three novel(More)
AIM The aim of this study was to investigate morphologic changes of retina and sclera in form-deprived myopic rabbits following intravitreal dopamine injection. METHODS Neonatal rabbits were monocularly deprived of form vision by suturing the right eyelids after natural eye opening. In the form deprivation (FD) group, the right eye received FD alone. In(More)
PURPOSE To assess and compare the dry-eye-associated parameters and corneal biomechanical status after small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK). METHODS Sixty-five patients' (128 eyes) were collected between November 2012 and April 2013. Thirty-five (69 eyes) underwent SMILE and thirty(More)
We exploited a precursor-template route to chemically synthesize NaNbO3 nanobelt arrays. Na7(H3O)Nb6O19·14H2O nanobelt precursor was firstly prepared via a hydrothermal synthetic route using Nb foil. The aspect ratio of the precursor is controllable facilely depending on the concentration of NaOH aqueous solution. The precursor was calcined in air to yield(More)
A size-controlled Zn(OH) 2 template is used as a case study to explain the chemical strategy that can be executed to chemically engineering various nanoscale cavities. Zn(OH) 2 octahedron with 8 vertices and 14 edges is fabricated via a low temperature solution route. The size can be tuned from 1 to 30 lm by changing the reaction conditions. Two methods can(More)
To improve the contact between platinum catalyst and titanium substrate, a layer of TiO 2 nanotube arrays has been synthesized before depositing Pt nanoflowers by pulse electrodeposition. Dramatic improvements in electrocatalytic activity (3×) and stability (60×) for methanol oxidation were found, suggesting promising applications in direct methanol fuel(More)
PURPOSE To evaluate the efficacy of silicone hydrogel contact lenses on ocular surface after Sub-Bowman Keratomileusis (SBK). MATERIALS AND METHODS Forty-six patients suffered from myopia underwent a bilateral SBK. Post-operatively, one eye of each patient wore a PureVision contact lens for 24 h as a treated eye and the contralateral eye was as a blank(More)
PURPOSE To compare the effects of a combined wavefront-guided and aspheric ablation profile with an aspheric ablation profile alone to correct myopia in patients with a preoperative total higher-order aberration root mean square (HOA RMS) lower than 0.30 μm in both eyes. SETTING Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China. (More)
Image degradation by loss of higher spatial frequencies causes form-deprivation myopia (FDM) in humans and animals, and cyclical illumination (flicker) at certain frequencies may prevent FDM. The molecular mechanisms underlying FDM and its prevention by flicker are poorly known. To understand them better, we have identified proteins that differ in amount in(More)
