Bidirectional associations among gallstone disease, non-alcoholic fatty liver disease, kidney stone disease.

Background: A body of evidence has suggested bidirectional relationships among gallstone disease (GSD), non-alcoholic fatty liver disease (NAFLD), and kidney stone disease (KSD). However, the results are inconsistent, and studies on this topic in China are relatively few. Our goal is to explore the bidirectional associations among these three diseases through a multicenter study, systematic review, and meta-analysis.

Sulfur-Vacancy Engineering Accelerates Rapid Surface Reconstruction in Ni-Co Bimetal Sulfide Nanosheet for Urea Oxidation Electrocatalysis.

Developing a highly efficient catalyst for electrocatalytic urea oxidation reaction (UOR) is not only beneficial for the degradation of urea pollutants in wastewater but also provides a benign route for hydrogen production. Herein, a sulfur-vacancy (S) engineering is proposed to accelerate the formation of metal (oxy)hydroxide on the surface of Ni-Co bimetal sulfide nanosheet arrays on nickel foam (S-CoNiS@NF) for boosting the urea oxidation electrocatalysis. As a result, the obtained S-CoNiS@NF demonstrates an outstanding electrocatalytic UOR performance, which requires a low potential of only 1.
