The electron distribution in the “activated” state of cytochrome c oxidase

Scientific Reports, 2018
Cytochrome c oxidase catalyzes reduction of O2 to H2O at a catalytic site that is composed of a copper ion and heme group. The reaction is linked to translocation of four protons across the membrane for each O2 reduced to water.

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

Advanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Apoptosis of THP-1 Macrophages Induced by Pseudohypericin-Mediated Sonodynamic Therapy Through the Mitochondria-Caspase Pathway

Cellular Physiology and Biochemistry, 2016
Background/Aims: Pseudohypericin (P-HY) and its congener hypericin are the major hydroxylated phenanthroperylenediones present in Hypericum species. Our previous study indicated that hypericin was able to function as a sonosensitizer.

Automated Transcranial Photobiomodulation in Healthy Rats: Effects on Working Memory and Brain Markers

Advanced Therapeutics, EarlyView.
Transcranial photobiomodulation (PBM) enhances spatial working memory in healthy rats under both continuous and alternating stimulation protocols. At the neural level, PBM modulates cytochrome c oxidase activity, increases prefrontal and hippocampal synaptic markers, and induces region‐specific c‐Fos expression. These effects suggest improved cognitive
