A 37-year-old Bangladeshi male presented with an inferotemporal optic disk pit and serous macular detachment in the left eye. Imaging with spectral domain optical coherence tomography (OCT) revealed a multilayer macular schisis pattern with a small subfoveal outer retinal dehiscence. This case illustrates a rare phenotype of optic disk maculopathy with macular schisis and a small outer retinal ...

18-Methyleicosanoic acid (18-MEA) is thought to be covalently bound to the outer surface of human hair and is a major component of the outer beta-layer of the cuticular cell membrane complex (CCMC). Cuticular delamination, whether this occurs between the outer beta- and delta-layers or within the plane of the beta-layer, results in a fresh layer of 18-MEA being exposed at the newly-revealed sur...

High-resolution particle image velocimetry measurements are made in the streamwise–wall-normal plane of a zero-pressure-gradient turbulent boundary layer over smooth and rough walls at Re 13000. The roughness considered herein is replicated from a surface scan of a turbine blade damaged by deposition of foreign materials and its topography is highly irregular and contains a broad range of topog...

BACKGROUND Paraneoplastic retinopathy is caused by the cross-reaction of neoplasm-directed autoantibodies against retinal antigens and results in retinal damage. Paraneoplastic vitelliform retinopathy, a presumed paraneoplastic retinopathy with features of atypical melanoma-associated retinopathy, has recently been reported in patients with metastatic melanoma. Ocular ultrastructure and its aut...

Zinc is associated with glutamatergic pathways in brain and retina, yet its role in neuromodulation remains unknown. High concentrations of reactive zinc in vertebrate photoreceptor terminals suggest a neuromodulatory role in the outer plexiform layer but zinc release has not been demonstrated. Using the membrane-impermeable form of the Zn(2+) sensitive fluorescent dye Newport Green, we have de...

PURPOSE To evaluate structure and function of macular retinal layers in nonhuman primate (NHP) experimental glaucoma (EG). METHODS Twenty-one NHP had longitudinal imaging of macular structure by SDOCT, 16 also had recordings of function by multifocal ERG. The average thickness over 15° was derived for seven individual SDOCT layers: macular nerve fiber layer (m-NFL), retinal ganglion cell laye...

Electrochemical, acoustic wave and imaging (AFM) methods were used to characterize electroactive poly[Ni(3-Mesalophen-b15-c5)] films. The distinct physical principles of these techniques generate different responses to film characteristics, such that their simplistic correlation in the context of a single uniform film model does not adequately describe the data. Film behaviour can only be ratio...

Background and Objectives: Onion (Allium cepa L.) possesses aromas and flavours, which have made them one of important ingredients of food. In addition, recent publications have reported that onion and its extract have many biological properties such as antimicrobial and antioxidant. Yellow and White Sweet Spanish onions belonging to Amaryllidaceae, are cultivated all over Iran as a condiment, ...

OBJECTIVES To compare different screening procedures for hydroxychloroquine sulfate (Plaquenil) toxicity at different stages of damage. METHODS Ten patients were studied using 10-2 automated fields, multifocal electroretinography, spectral domain optical coherence tomography (SD-OCT), and fundus autofluorescence. RESULTS All 10 patients used hydroxychloroquine for more than 6 years, and tho...

These are model studies whose aim is to obtain information that would allow development of new technology for synthesizing monolayers of Al2O3-C with adjusted microstructure on cemented carbides. The Al2O3-C layer will constitute an intermediate layer on which the outer layer of Al2O3 without carbon is synthesized. The purpose of the intermediate layer is to block the cobalt diffusion to the sy...
