The effect of p66shc protein on the resistance of the RKO colon cancer cell line to oxidative stress

P66shc protein is an alternative transcript product of the SHC1 gene. Whereas two other isoforms (p52shc and p46shc) have adaptor function in the RAS signaling pathway, p66shc regulates the amount of reactive oxy...

Activation and structural and adsorption features of activated carbons with highly developed micro-, meso- and macroporosity

Three sets of activated carbons (ACs) were prepared with the same precursor but activated differently (by CO₂ or water vapour) with various burn-off levels. The ACs demonstrate increased deviation of the pore sha...
