Social Perceptions of Pediatric Hearing Aids.
Laryngoscope
July 2021
Department of Otolaryngology-Head & Neck Surgery, Stanford University School of Medicine, Stanford, California, U.S.A.
Objectives: To determine whether hearing aid (HA) use affects social perceptions of general public adults and age-matched peers and if so, determine if effects are modulated by lack of societal representation of pediatric HAs.
Methods: A 10-year-old boy was presented in six photographic conditions with and without HAs and eyeglasses (a worn sensory aid with wider societal representation). HAs were presented in neutral skin tone and bright blue colors.

Luminescence

Department of Biology, Hamamatsu University School of Medicine, Higashiku, Hamamatsu, Japan.
Larvae of the weakly blue-luminescent fungus gnat Keroplatus nipponicus possess on either side of their heads a small black stemmatal eye with a plano-convex lens approximately 25 μm in diameter. In total, 12-14 retinula cells give rise to a centrally fused rhabdom of up to 8 μm in diameter. The rhabdom's constituent microvilli, approximately 70 nm in width, are roughly orthogonally oriented, a requirement for polarization sensitivity.

Invest Ophthalmol Vis Sci
July 2015
Division of Clinical Neurology Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, United Kingdom.
Purpose: Severe visual impairment can have a profound impact on personal independence through its effect on mobility. We investigated whether the mobility of people with vision low enough to be registered as blind could be improved by presenting the visual environment in a distance-based manner for easier detection of obstacles.
Methods: We accomplished this by developing a pair of "residual vision glasses" (RVGs) that use a head-mounted depth camera and displays to present information about the distance of obstacles to the wearer as brightness, such that obstacles closer to the wearer are represented more brightly.
The cellular basis for biocide-induced fluorescein hyperfluorescence in mammalian cell culture.

Clinical examination of the ocular surface is commonly carried out after application of sodium fluorescein in both veterinary and medical practice by assessing the resulting 'staining'. Although localized intensely stained regions of the cornea frequently occur after exposure to 'adverse' clinical stimuli, the cell biology underlying this staining is unknown, including whether intense fluorescein staining indicates the presence of damaged cells. Ocular exposure to certain contact lens multipurpose solutions (MPS) gives rise to intense fluorescein staining referred to as solution induced corneal staining (SICS), and we have made use of this phenomenon with Vero and L929 cell culture models to investigate the fundamental biology of fluorescein interactions with cells.
