Endothelial Cytotoxicity of Drug‐Doped Polypyrrole Coatings on Biodegradable Iron for Stent Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
Electrochemically deposited polypyrrole coatings doped with salicylate and dexamethasone are tested on iron substrates. Their safety for biological use is confirmed in vitro with human endothelial cells. Abstract Conducting polymers, such as polypyrrole (PPy), are promising coatings for biodegradable vascular implants due to their electrical ...

Apc mutation induces resistance of colonic cells to lipoperoxide-triggered apoptosis induced by faecal water from haem-fed rats [PDF]

open access: yes, 2006
Recent epidemiological studies suggest that high meat intake is associated with promotion of colon cancer linked to haem-iron intake. We previously reported that dietary haem, in the form of either haemoglobin or meat, promotes precancerous lesions in ...

Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions

open access: yesAdvanced Science, EarlyView.
Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.
