A single cell death is disruptive to spontaneous Ca2+ activity in astrocytes

open access: yesFrontiers in Cellular Neuroscience, 2022
Astrocytes in the brain are rapidly recruited to sites of injury where they phagocytose damaged material and take up neurotransmitters and ions to avoid the spreading of damaging molecules.

Comparison of the RADM2 and RACM chemical mechanisms in O3 simulations: effect of the photolysis rate constant

open access: yesScientific Reports, 2021
Since the photolysis rate plays an important role in any photoreaction leading to compound sink and radical formation/destruction and eventually O3 formation, its impact on the simulated O3 concentration was evaluated in the present study. Both RADM2 and
