In vivo laser Doppler holography of the human retina

open access: yes, 2018
The eye offers a unique opportunity for non-invasive exploration of cardiovascular diseases. Optical angiography in the retina requires sensitive measurements, which hinders conventional full-field laser Doppler imaging schemes.

Ultrasound-targeted microbubble destruction enhances AAV mediated gene transfection: human RPE cells in vitro and the rat retina in vivo [PDF]

open access: yes, 2009
The present study was performed to investigate the efficacy and safety of Ultrasound-targeted microbubble destruction (UTMD) mediated rAAV2-EGFP to cultured human retinal pigment epithelium (RPE) cells _in vitro_ and the rat retina _in vivo_.

Programmable retinal dynamics in a CMOS mixed-signal array processor chip [PDF]

open access: yes, 2003
The low-level image processing that takes place in the retina is intended to compress the relevant visual information to a manageable size. The behavior of the external layers of the biological retina has been successfully modelled by a Cellular Neural ...

Hardware Coupled Nonliear Oscillators as a Model of Retina [PDF]

open access: yes, 1995
An electronic circuit consisting of coupled nonlinear oscillators⁴'⁵ simulates the spatiotemporal processing in retina. Complex behavior recorded in vivo from ganglion cells in the cat retina 6 in response to flickering light spots is matched by setting ...

From monoclonal antibody to gene for a neuron-specific glycoprotein in Drosophila [PDF]

open access: yes, 1985
A monoclonal antibody (MAb24B10), derived from mice immunized with Drosophila retina, exclusively stains photoreceptor cells in the retina and their axonal projections to the optic ganglia. The antigen (Ag24B10) is a 160-kDa glycoprotein comprising about

Distribution of melanopsin positive neurons in pigmented and albino mice: evidence for melanopsin interneurons in the mouse retina. [PDF]

open access: yes, 2014
Here we have studied the population of intrinsically photosensitive retinal ganglion cells (ipRGCs) in adult pigmented and albino mice. Our data show that although pigmented (C57Bl/6) and albino (Swiss) mice have a similar total number of ipRGCs, their ...

Intravitreal Administration of Human Bone Marrow CD34+ Stem Cells in a Murine Model of Retinal Degeneration. [PDF]

open access: yes, 2016
PurposeIntravitreal murine lineage-negative bone marrow (BM) hematopoietic cells slow down retinal degeneration. Because human BM CD34+ hematopoietic cells are not precisely comparable to murine cells, this study examined the effect of intravitreal human

Programmable active pixel sensor to investigate neural interactions within the retina [PDF]

open access: yes, 2009
Detection of the visual scene by the eye and the resultant neural interactions of the retina-brain system give us our perception of sight. We have developed an Active Pixel Sensor (APS) to be used as a tool for both furthering understanding of these ...

Immobilisation of E. coli by Microarray Printing. [PDF]

open access: yes, 2018
Cellular heterogeneity is a fundamental property of organisms that help them to adapt and thrive in different changing environmental conditions. Therefore, approaches are necessary to study cellular processes at a single cell resolution.

Human visual response to nuclear particle exposures [PDF]

open access: yes, 1972
Experiments with accelerated helium ions were performed in an effort to localize the site of initial radiation interactions in the eye that lead to light flash observations by astronauts during spaceflight.
