Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor

open access: yesAdvanced Science, EarlyView.
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.

Regulation of scleral fibroblast differentiation by bone morphogenetic protein-2

open access: yesInternational Journal of Ophthalmology, 2014
Bone morphogenesis proteins (BMPs) are multi-functional growth factors. They are expressed in retina, retinal pigment epithelium (RPE) and sclera and serve as a regulator in the growth and development of the eye.

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Nanostructured drug delivery systems for posterior segment eye diseases: Strategies to defy ocular barriers

open access: yesBMEMat, EarlyView.
Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

open access: yesInterdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

Hypoxia‐Induced Histone Lactylation Promotes Ferroptosis in Cardiomyocytes via the Wnt/β‐Catenin Pathway

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study investigated the effects of histone lactylation on ferroptosis in hypoxia‐induced cardiomyocytes. A hypoxia model was established in AC16 cells treated with 2‐Deoxy‐D‐glucose (2‐DG, a glucose analogue), ferrostatin‐1 (Fer‐1, a selective ferroptosis inhibitor), lactate (LA), sh‐β‐catenin (shRNA of β‐catenin), or SKL2001 (an agonist ...

A Subdomain Method for Mapping the Heterogeneous Mechanical Properties of the Human Posterior Sclera

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
Although strongly correlated with elevated intraocular pressure, primary open-angle glaucoma (POAG) occurs in normotensive eyes. Mechanical properties of the sclera around the optic nerve head (ONH) may play a role in this disparity.

Customized Scattering‐Robust 3D Speckle Correlation for Improved Resolution and Imaging Depth in Scattering Tissue

open access: yesLaser &Photonics Reviews, EarlyView.
A scattering‐robust 3D speckle customization method is proposed to enhance both resolution and imaging depth in scattering tissue. Applied to light‐field microscopy (LFM), it improves 3D resolution by over twofold under strong optical scattering. In wide‐field fluorescence imaging, it enables a substantial improvement in imaging depth, allowing imaging
