this paper presents a new three-dimensional curvelet transform based dictionary learning for automatic segmentation of intraretinalcysts, most relevant prognostic biomarker in neovascular age-related macular degeneration, from 3d spectral-domain optical coherencetomography (sd-oct) images. in particular, we focus on the spectralis sd-oct (heidelberg engineering, heidelberg, germany) system, and...
The retinal pigmented epithelium (RPE) is a monolayer of specialized epithelial cells located between the photoreceptors of the retina and the choroidal blood supply. The RPE is essential for maintaining retinal health and vision. Recent findings identified STAT3 as a newly recognized regulator of RPE survival, inflammatory response, visual cycle maintenance, and cytokine release. Additionally,...
Organotypic epithelial raft cultures as a model for evaluating compounds against alphaherpesviruses.
The course of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) and varicella-zoster virus (VZV) infections in squamous epithelial cells cultured in a three-dimensional organotypic raft culture was tested. In these raft cultures, normal human keratinocytes isolated from neonatal foreskins grown at the air-liquid interface stratified and differentiated, reproducing a fully differentiated ep...
The present study was designed to investigate the histological lesions in lungs of white mice infected with Aspergillus fumigatus by intraperitoneal injection, nasal implantation, current research also examined an attempt treat these tissue using both antifungal Amphotericin B and alcoholic extract Trametes for two weeks. results showed that A. led changes represented degeneration, desquamation...
The purpose of this study was to evaluate the effects of zinc oxide nanoparticles and ions on intestinal tissue histopathology of freshwater crayfish (Astacus leptodactylus) under laboratory conditions. We evaluated two concentrations of zinc oxide nanoparticles and zinc ions (0.5 µm/l and 1.0 mg/l) with a control group. After 14 days of exposure to the nanoparticles of zinc oxide and zinc ions...
The present study has been designed to evaluate the liver protective and in-vivo antioxidant role of Ethanolic extract (EtAS) and Ethyl acetate extract (EAAS) of roots of Argyreia speciosa, an important 'rasayana' herb in Indian System of medicine, in CCl(4)-induced hepatotoxicity and oxidative stress in rats. Animals were treated with EtAS and EAAS at doses of 200 mg and 400 mg/kg body weight ...
Background: Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world and is characterized by progressive degeneration of the retinal pigment epithelium and secondary photoreceptor loss, resulting in visual loss. Etiological research suggests that age related macular degeneration is a complex disease, caused by the interactions of several genetic and enviro...
Introduction: Age-related macular degeneration (AMD) is one of the retina diseases in which retinal pigment epithelium cells are degraded and lead to blindness. Available treatments only slow down the progression of it. In this study, human embryonic stem cells (hESCs) differentiated into retinal pigment epithelium cells were cultured on a polycaprolactone scaffold. Methods: The optimization o...
