Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.
