VEGF guides angiogenic sprouting utilizing endothelial tip cell filopodia [PDF]
, 2003 Vascular endothelial growth factor (VEGF-A) is a major regulator of blood vessel formation and function. it controls several processes in endothelial cells, such as proliferation, survival, and migration, but it is not known how these are coordinately ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Neuromyelitis Optica Spectrum Disorder (NMOSD) is a chronic autoimmune neuroinflammatory disease, typically characterized by antibodies against aquaporin 4 (AQP4‐IgG) or myelin oligodendrocyte glycoprotein (MOG‐IgG). Simultaneous seropositivity for both antibodies in a single patient is exceedingly rare.

Macular Hole Progression after Intravitreal Bevacizumab for Hemicentral Retinal Vein Occlusion
Case Reports in Ophthalmological Medicine, 2011 Macular edema secondary to retinal vein occlusion is commonly being treated with off-label intravitreal bevacizumab with good outcomes. A significant reduction in macular edema and improvement in visual acuity is seen following such a treatment with no ...

A spatial contrast retina with on-chip calibration for neuromorphic spike-based AER vision systems [PDF]
, 2007 We present a 32 32 pixels contrast retina microchip that provides its output as an address event representation (AER) stream. Spatial contrast is computed as the ratio between pixel photocurrent and a local average between neighboring pixels obtained ...

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]
, 2017 The light absorbing chromophore in opsin visual pigments is the protonated Schiff base of 11-cis-retinaldehyde (11cRAL). Absorption of a photon isomerizes 11cRAL to all-trans-retinaldehyde (atRAL), briefly activating the pigment before it dissociates ...
