Effect of nano zinc oxide or chelated zinc as alternatives to medical zinc oxide on growth performance, faecal scores, nutrient digestibility, blood profiles and faecal Escherichia coli and Lactobacillus concentrations in weaned piglets

Italian Journal of Animal Science, 2022
A total of 144 weaned piglets (6.80 ± 0.46 kg, [Landrace × Yorkshire] × Duroc) were used in a 4-week feeding trial to determine the effect of nano zinc oxide or chelated zinc as alternatives to medical zinc oxide (ZnO) in weaned piglets.

Research progress on mechanisms bacteriostasis and affecting factors of nano-zinc oxide

Siliao yanjiu, 2021
The nano-zinc oxide has a better astringent, disinfection and bacteriostasis effects than ordinary zine oxide. The paper reviews three aspects of nano-zinc oxide in bacteriostasis, namely contact, Zn2+ and free radical, respectively, and summarizes three

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

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

FEBS 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 ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
