Au-decorated Sb 2 Se 3 photocathodes for solar-driven CO 2 reduction
A nano-structured photoelectrode made from Sb 2 Se 3 was prepared and was utilized for CO 2 reduction. Au nanoparticle catalysts were deposited to facilitate CO formation
Glutathione Restores the Mechanism of Synaptic Plasticity in Aged Mice to That of the Adult
Glutathione (GSH), the major endogenous antioxidant produced by cells, can modulate the activity of N-methyl-D-aspartate receptors (NMDARs) through its reducing functions. During aging, an increase in oxidative stress leads to decreased levels of GSH in the brain. Concurrently, aging is characterized by calcium dysregulation, thought to underlie impairments in hippocampal NMDAR-dependent long-term potentiation (LTP), a form of synaptic plasticity thought to represent a cellular model for memory
Interocular amplitude differences of multifocal electroretinograms obtained under monocular and binocular stimulation conditions
Purpose:
To compare the interocular amplitude differences of the multifocal electroretinograms (mfERGs) evoked by either monocular or binocular stimulation in healthy subjects with good vision.
Methods:
Thirty-five subjects were included in the study. A Roland Consult RETIscan system was used. DTL electrodes were employed. First, the right and left eyes were stimulated separately, then, binocular stimulation was applied. The amplitudes of the scalar products were averaged over five concentric retinal regions (rings).
Results:
The interocular amplitude differences were 21.55% (SD: ±12.72) under monocular conditions and 18.69% (SD: ±11.64) under binocular conditions. No significant differences were found between the amplitudes and variability values obtained under either monocular or binocular stimulation.
Conclusions:
Our results provided no evidence for the advantage of either binocular or monocular stimulating conditions in obtaining mfERGs. A considerable side difference was found between the mfERGs of the two eyes in almost all individual cases
