JHEP Rep. 2021 Nov 12;4(1):100392. doi: 10.1016/j.jhepr.2021.100392. eCollection 2022 Jan.

BACKGROUND & AIMS: Increased serum bile acids (BAs) have been observed in patients with non-alcoholic steatohepatitis (NASH). Pegbelfermin (PGBF), a polyethylene glycol-modified (PEGylated) analogue of human fibroblast growth factor 21 (FGF21), significantly decreased hepatic steatosis and improved fibrosis biomarkers...

Enzyme-Inspired Iron Porphyrins for Improved Electrocatalytic Oxygen Reduction and Evolution Reactions.

Angewandte Chemie (International ed. in English)

Xie L, Zhang XP, Zhao B, Li P, Qi J, Guo X, Wang B, Lei H, Zhang W, Apfel UP, Cao R.

OBJECTIVE: Hospitalized patients placed in isolation due to a carrier state or infection with resistant or highly communicable organisms report higher rates of anxiety and loneliness and have fewer physician encounters, room entries, and vital sign records. We hypothesized...

Sulfur substitution in a Ni(cyclam) derivative results in lower overpotential for CO.

Dalton transactions (Cambridge, England : 2003)

Gerschel P, Warm K, Farquhar ER, Englert U, Reback ML, Siegmund D, Ray K, Apfel UP.
PMID: 30624449
Dalton Trans. 2019 May 07;48(18):5923-5932. doi: 10.1039/c8dt04740e.

The replacement of the opposing nitrogen atoms in 1,4,8,11-tetraazacyclotetradecane (cyclam) with two sulfur atoms in 1,8-dithia-4,11-diazacyclotetradecane (dithiacyclam) enables the electrochemical reduction of protons and CO2via the corresponding nickel(ii) complex at more positive potentials. In addition, a 10-fold enhancement in...

Water-Soluble Polymers with Appending Porphyrins as Bioinspired Catalysts for the Hydrogen Evolution Reaction.

Angewandte Chemie (International ed. in English)
