The prevalence of hypercholesterolaemia and hypertension was higher among those categorized in the lowest tertile of
haem protein intake (p<0.
Falcipain-II and falcipain-III are reported as

The second speculates that artemisinin is uniquely activated by
haem in malaria vacuoles.
Erythropoietic protoporphyria (EPP) is an autosomal dominant defect in

Hydrogen sulphide poisoning: blood sulphide concentration and changes in
haem metabolism.
Carnitine-mediated improved response to erythropoietin involves induction of
haem oxygenase-1: studies in humans and in an animal model.
If plasma CK continues to rise, forced diuresis using mannitol can minimise intratubular

Unconjugated bilirubin is produced by the breakdown of
haem, which is found in red blood cells.
Nitric oxide binds to the
haem moiety of guanylate cyclase and increases its activity by 400-fold, catalyzing the conversion of guanosine triphosphate to cyclic guanosine monophosphate (cGMP).
