In Vivo and In Vitro Evaluation of PTeCA (1H‐Pyrrole‐2,3,4,5‐Tetracarboxylic Acid) in Hair Matrix as a Marker for Oxidative Cosmetic Treatment

Drug Testing and Analysis, EarlyView.
A total of 3378 self‐reported treated and untreated hair samples were analyzed for PTCA and PTeCA by LC‐MS/MS. Moreover, their in vitro formation was assessed in 225 untreated hair by different cosmetic treatments with and without oxidative agents. Data suggest that PTeCA could be a reliable marker for oxidative cosmetic treatments in hair.

Chemical Composition, Amino Acids, Phenolic Profiles and Bioavailability of Minerals in Livingstone Potato (Plectranthus esculentus) as Affected by Different Processing Techniques

Food Chemistry International, EarlyView.
Boiling retained the nutrients and polyphenol compounds in Plectranthus esculentus tubers better than frying or roasting. A bioavailability study showed that the phytates and oxalates in the tuber may not affect the bioavailabilities of calcium, zinc, or iron in Plectranthus esculentus tubers when eaten.
