Comparison of macro x‐ray fluorescence and reflectance imaging spectroscopy for the semi‐quantitative analysis of pigments in easel paintings: A study on lead white and blue verditer

open access: yesX-Ray Spectrometry, Volume 53, Issue 6, Page 438-451, November/December 2024.
Abstract Macroscopic x‐ray fluorescence imaging spectroscopy (MA‐XRF) and reflectance imaging spectroscopy (RIS) are important tools in the analysis of cultural heritage objects, both for conservation and art historical research purposes. The elemental and molecular distributions provided by MA‐XRF and RIS respectively, are particularly useful for the ...

Improvement of intestinal microbial structure in patients with cerebral infarction through in vitro fermentation of anthocyanins from Lycium ruthenicum Murray

open access: yesFood Science &Nutrition, Volume 12, Issue 10, Page 7481-7491, October 2024.
The in vitro fermentation product of Lycium ruthenicum Murray anthocyanins significantly increased the diversity of the intestinal microbiota in patients with cerebral infarction. ACN promoted the proliferation of beneficial bacteria and decreased the growth of potentially harmful bacteria in the gut of patients with acute cerebral infarction.
