Self‐Supervised Learning‐Based Framework for Speckle Reduction of Optical Coherence Tomography Images Using Frame Interpolation

Advanced Intelligent Systems, EarlyView.
In summary, a self‐supervised end‐to‐end framework for OCT image despeckling is proposed, without access to unpaired noisy–clean images or paired noisy–noisy images for training. The despeckling performance has been evaluated on 150 subjects from five retina datasets (121 subjects) and one middle ear dataset (29 subjects). Optical coherence tomography (

Age-related macular degeneration

Community Eye Health Journal, 2014
Age-related macular degeneration (AMD) is a disease of the retina that usually develops in people aged 60 years and older. It affects about 8.7% of the world’s population and is the leading cause of blindness among people aged 50 and older in ...

A Novel HDL-Mimetic Peptide HM-10/10 Protects RPE and Photoreceptors in Murine Models of Retinal Degeneration. [PDF]

, 2019
Age-related macular degeneration (AMD) is a leading cause of blindness in the developed world. The retinal pigment epithelium (RPE) is a critical site of pathology in AMD. Oxidative stress plays a key role in the development of AMD.

Poland Anomaly and Atretic Cephalocele in the Same Child: Coincidence or Association?

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Poland Anomaly is a rare congenital disorder typically characterized by hypoplasia or agenesis of pectoral muscle with or without ipsilateral limb hypoplasia. The association of central nervous system malformation with Poland Anomaly has been rarely reported and includes craniofacial dysplasia, microcephaly, and Dandy‐Walker malformation ...

Establishment of a novel alloxan‐induced rabbit model exhibiting unique diabetic retinal neuropathy features assessed via ERG + VEP

Animal Models and Experimental Medicine, EarlyView.
Study workflow. Neuroretinal changes were observed in alloxan‐induced diabetic rabbits, while the retinal vasculature remained unaffected, indicating the successful establishment of a diabetic neuroretinal model. Abstract Background Diabetic retinal neuropathy (DRN) leads to significant visual impairment; however, no existing animal model fully ...

Tuning Cellular Perception in Pluripotent Stem Cells through Topography, Stiffness, and Patterning

Advanced NanoBiomed Research, EarlyView.
Micro‐ and nanotopographical cues, substrate stiffness, and mechanical patterning synergistically direct pluripotent stem cell fate and function by tuning cellular perception at the biointerface. Pluripotent stem cells (PSCs), comprised of embryonic stem cells and induced PSCs, hold tremendous therapeutic potential.
