Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Effects of CO32− and OH− on the solubility, metastable zone width and nucleation kinetics of borax decahydrate [PDF]

open access: yesRoyal Society Open Science, 2019
Measurements of the solubility and metastable zone width (MZW) of borax decahydrate in sodium carbonate and sodium hydroxide aqueous were obtained. The onsets of nucleation were detected by the turbidity technique with the temperature range from 285 to ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Effect and mechanisms of sodium carbonate on the auto-carrier flotation of scheelite

open access: yes工程科学学报, 2019
Because of the low recovery of -10 μm fine scheelite particles in scheelite flotation, some amount of fine scheelite is lost in the tailing, resulting in the wasting of scheelite resources.

SODIUM CARBONATE IN CHLOROFORM POISONING [PDF]

open access: yesArchives of Internal Medicine, 1920
In 19151I described some experiments which indicated that chloroform is dissociated in the body in such a way that free hydrochloric acid is formed from it and that the toxic effects of chloroform are probably to a great extent due to the action of the liberated hydrochloric acid. The evidence on which this view was based was as follows: 1. The ease of

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
