Abstract Background The metabolome of COVID-19 patients has been studied sparsely, with most research focusing on a limited number plasma metabolites or small cohorts. This is the first study to test saliva in comprehensive way, revealing significant changes linked disease severity and highlighting potential as non-invasive diagnostic tool. Methods We included 30 asymptomatic subjects no prior infection vaccination, 102 mild SARS-CoV-2 infection, 61 hospitalized confirmed status. Saliva samples were analyzed using hydrophilic interaction liquid chromatography-mass spectrometry (HILIC-MS/MS) positive negative ionization modes. Results Significant identified patients, distinct patterns based severity. Healthy individuals exhibited well-regulated bacterial network, while severe cases showed disordered microbial networks. Elevated dipeptides such Val-Glu Met-Gln moderate suggest specific protease activity related SARS-CoV-2. Increased acetylated amino acids like N-Acetylserine N-Acetylhistidine indicate biomarkers for stress Bacterial metabolites, including muramic acid indole-3-carboxaldehyde, higher mild-moderate cases, indicating oral microbiota changes. In polyamines organ damage-related N-acetylspermine 3-methylcytidine, significantly increased. Interestingly, reduced elevated cases. Conclusions metabolomics offers insight into progression COVID-19.

The aim this study was examine morphophysiological metabolic changes in tomato plants foliarly treated two protein hydrolysates obtained by enzymatic hydrolysis vegetal proteins from Malvaceae (PH1) or Fabaceae (PH2) comparison a control treatment, as well investigate mechanisms involved enhancement plant resistance repeated stress cycles. Methods A device used daily monitoring traits while untargeted carried out leaves best performing treatment based on phenotypic results. Results PH1 most water due better recovery digital biomass 3D leaf area after each event PH2 mitigating only during period first event. Metabolomics data indicated that modified primary metabolism increasing concentration dipeptides fatty acids untreated control, secondary regulating several compounds like phenols. In contrast, hormones detoxification signal molecules against reactive oxygen species were downregulated control.

Abstract Climate change is responsible for mild winters and warm springs that can induce premature plant development, increasing the risk of exposure to cold stress with a severe reduction in growth. Tomato plants are sensitive beneficial microorganisms increase their tolerance. However, scarce information available on mechanisms stimulated by bacterial endophytes tomato against stress. This study aimed clarify metabolic changes psychrotolerant endophytic bacteria exposed annotate compounds possibly associated mitigation. seeds were inoculated two isolated from Antarctic Colobanthus quitensis ( Ewingella sp.

The composition was analyzed immediately after (4°C seven days) four days recovery at 25°C. Under stress, content malondialdehyde, phenylalanine, ferulic acid, p‐coumaric acid lower bacterium‐inoculated compared plants, indicating lipid peroxidation stimulation phenolic compound metabolism. compounds, five putative phenylalanine‐derived dipeptides, three further higher samples under Thus, reprogram polyphenol metabolism stimulate accumulation secondary metabolites, like 4‐hydroxybenzoic salicylic which presumably involved mitigation, dipeptides responses.
