Ascites is one of the most common complications of cirrhosis, and there is a dearth of knowledge about ascites-related pathologic metabolism. In this study, 122 alcoholic liver disease (ALD) patients, including 49 cases without ascites, 18 cases with mild-ascites, and 55 cases with large-ascites (1) were established according to the International Ascites Club (2), and untargeted metabolomics coupled with pattern recognition approaches were performed to profile and extract metabolite signatures. A total of 553 metabolites were uniquely discovered in patients with ascites, of which 136 metabolites had been annotated in the human metabolome database. Principal component analysis (PCA) analysis was used to further identify 21 ascites-related fingerprints. The eigenmetabolite calculated by reducing the dimensions of the 21 metabolites could be used to effectively identify those ALD patients with or without ascites. The eigenmetabolite showed a decreasing trend during ascites production and accumulation and was negatively related to the disease progress. These metabolic fingerprints mainly belong to the metabolites in lipid metabolism and the amino acid pathway. The results imply that lipid and amino acid metabolism disturbance may play a critical role in the development of ascites in ALD patients and could be a potent prognosis marker.

Selenium promotes plant growth and improves nutritional quality, and the role of nano-selenium in alfalfa in regulating nutritional quality is unknown. In this study, using the N labeling method, it was found that nano-selenium could promote plant nitrogen metabolism and photosynthesis by increasing the light energy capture capacity and the activities of key enzymes of the nitrogen metabolism process, leading to an increase in alfalfa nitrogen accumulation and dry matter content. The transcriptome and metabolome revealed that nano-selenium mainly affected the pathways of 'biosynthesis of amino acids', 'starch and sucrose metabolism', 'pentose and glucuronate interconversions', 'pentose phosphate pathway', and 'flavonoid biosynthesis'.

Background: Despite numerous genetic studies on Infectious Bronchitis Virus (IBV), many strains from the Middle East remain misclassified or unclassified. Genotype 1 (GI-1) is found globally, while genotype 23 (GI-23) has emerged as the predominant genotype in the Middle East region, evolving continuously through inter- and intra-genotypic recombination. The GI-23 genotype is now enzootic in Europe and Asia.

The extensive presence of per-/polyfluoroalkyl substances (PFASs) in the environment and their adverse effects on organisms have garnered increasing concern. With the shift of industrial development from legacy to emerging PFASs, expanding the understanding of molecular responses to legacy and emerging PFASs is essential to accurately assess their risks to organisms. Compared with traditional toxicological approaches, omics technologies including transcriptomics, proteomics, metabolomics/lipidomics, and microbiomics allow comprehensive analysis of the molecular changes that occur in organisms after PFAS exposure.
