Psoriasis severity and treatment: Metabolomics uncovers amino acid biomarkers

Date: Dec 3, 2014

Author: Steve Down

A metabolomics study of the plasma from psoriasis sufferers has highlighted numerous circulating amino acids that increase in abundance with the severity of the disease but return towards normal levels following treatment with a protein drug that targets tumour necrosis factor alpha.

Liver damage by lead acetate: Oxidised proteins and cell damage

Date: Nov 24, 2014

Author: Steve Down

Exposure to lead acetate on the skin results in oxidation of protein in the liver that could ultimately cause liver damage, say Taiwanese researchers.
