The gap between academic research on proton exchange membrane water electrolysers and industrial demands Driven by carbon neutral targets, proton exchange membrane water electrolysis is becoming a hot technology due to its capability to convert fluctuating power into green hydrogen. Unfortunately, despite...

Elevated levels of membrane lipid peroxidation is a critical factor in the mechanism of ferroptosis [11]. To exclude a role for ferroptosis, we examined lipid peroxidation levels in osteosarcoma cells. Flow cytometry results revealed that cisplatin, with or without OTULIN knockdown, did not significan...
In addition, we explored the action of RV on the cell membrane by a well-consolidated biophysical approach: electrorotation. This technique allows assessment of the structure/function of the cell membrane. The results presented here demonstrate that RV shows a modest effect on the biological ...
4B). Membrane potential assays further indicated that AMP1 only had minimal impact on the cell membrane during the initial incubation period (Fig. 4C). However, with prolonged exposure, cell membranes gradually depolarized, with a marked increase in dead cells (Fig. 4C and D). Additionally, ...
2a)14,16. When triggered by 532-nm light, halorhodopsin hyperpolarizes the cell membrane, silencing electrically excitable cells instantly. In CckCRE_Halo mice, vagal responses to luminal sucrose, α-MGP and sucralose remained unchanged in the presence of the control 473-nm light14. However, ...
