GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]

open access: yes, 2001
Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...

The artificial retina for track reconstruction at the LHC crossing rate

open access: yes, 2014
We present the results of an R&D study for a specialized processor capable of precisely reconstructing events with hundreds of charged-particle tracks in pixel and silicon strip detectors at $40\,\rm MHz$, thus suitable for processing LHC events at the ...

HZO/HSO Superlattice ReFET Array Integrating Optical Sensing for Neuromorphic Vision Computing

open access: yesAdvanced Materials, EarlyView.
A photonic ReFET array with an engineered HZO–HSO superlattice enables monolithic integration of optical sensing, nonvolatile memory, and synaptic computation. It exhibits forming‐free, >8‐bit analog states, >1010 endurance cycles, and light‐tunable conductance.

GLIOMA OF THE RETINA. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1900
As glioma of the retina is not commonly met with, particularly in private practice, I venture to report the following case. More than a year ago, through the courtesy of Dr. P. J. Kline, of Portsmouth, Ohio, a 14-months-old girl was brought to me for treatment of the right eye. The parents stated that the eye did not seem natural in appearance at birth,

The First Review on Nano‐Agricultural Applications of MXene and MBene‐Based Materials for Plant‐Immunoengineering, Controlled Protection, and Inducing Biostimulation Mechanisms

open access: yesAdvanced Materials, EarlyView.
MXene and MBene nanomaterials show significant potential in addressing critical challenges in biomedicine, applied biology, agriculture, and the environment. From a nano‐agricultural perspective, this relatively young field has witnessed emerging advances towards applications for plant‐immunoengineering, biostimulation, and controlled delivery ...

Chromatin remodeling protein HELLS is critical for retinoblastoma tumor initiation and progression. [PDF]

open access: yes, 2020
Retinoblastoma is an aggressive childhood cancer of the developing retina that initiates by biallelic RB1 gene inactivation. Tumor progression in retinoblastoma is driven by epigenetics, as retinoblastoma genomes are stable, but the mechanism(s) that ...

The Bionic Interface: Considering the Material Mediated Electrical Stimulation of Stem Cells

open access: yesAdvanced Materials, EarlyView.
Electrical stimulation directs stem cell fate in tissue engineering. Cellular responses are influenced by membrane properties, intrinsic cell state, material charge‐transport characteristics, and the applied electrical signal. Additionally, a material’s ability to inject, store, and redistribute charge further modulates these responses.
