Influence of damaging and wilting red clover on lipid metabolism during ensiling and in vitro rumen incubation [PDF]

open access: yes, 2010
This paper describes the relationship between protein-bound phenols in red clover, induced by different degrees of damaging before wilting and varying wilting duration, and in silo lipid metabolism.

18F-Deoxyfluorination of Phenols via Ru π-Complexes

open access: yesACS Central Science, 2017
The deficiency of robust and practical methods for 18F-radiofluorination is a bottleneck for positron emission tomography (PET) tracer development. Here, we report the first transition-metal-assisted 18F-deoxyfluorination of phenols.

Unexpected transformation of dissolved phenols to toxic dicarbonyls by hydroxyl radicals and UV light. [PDF]

open access: yes, 2018
Water treatment systems frequently use strong oxidants or UV light to degrade chemicals that pose human health risks. Unfortunately, these treatments can result in the unintended transformation of organic contaminants into toxic products.

Asymmetric Oxidative Coupling of Phenols and Hydroxycarbazoles

open access: yesOrganic Letters, 2017
The first examples of asymmetric oxidative coupling of simple phenols and 2-hydroxycarbazoles are outlined. Generation of a more vanadium catalyst by ligand design and by addition of an exogenous Brønsted or Lewis acid was found to be key to coupling the

Functional role and folding properties of the glucan‐binding domain of oral bacterial glucansucrase

open access: yesFEBS Letters, EarlyView.
The role of the glucan‐binding domain in Streptococcus sobrinus glucansucrase was examined, focusing on its impact on enzymatic activity, dextran binding, and structural stability of deletion mutants and a circularly permuted protein. Our research revealed that glucosyl transfer efficiency is linked to cooperative interdomain folding.
