Open AccessHaem iron reshapes colonic luminal environment: impact on mucosal homeostasis and microbiome through aldehyde formation
The World Health Organization classified processed and red meat consumption as “carcinogenic” and “probably carcinogenic”, respectively, to humans. Haem iron from meat plays a role in the promotion of colorect...

Luminal sulfide and large intestine mucosa: friend or foe?
Hydrogen sulfide (H2S) is present in the lumen of the human large intestine at millimolar concentrations. However, the concentration of free (unbound) sulfide is in the micromolar range due to a large capacity of...
