Multi‐tissue Metabolic GWAS and Drought‐Responsive Multi‐omics Reveal the Genetic Basis of the Quinoa Metabolome

Advanced Science, EarlyView.
A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Tea Leaf Polyphenol Oxidase

Agricultural and Biological Chemistry, 1966
Polyphenol oxidase in tea leaves was fractionated to three components,called A-I, A-II and B, by the combination of DEAE and CM-cellulose column chromatographies. They exhibited different migration on starch-gel electrophoregram at pH 5.0. The results of CM-cellulose chromatography and starch-gel electrophoresis indicated that A-I and A-II were basic ...

Both 1-methylcyclopropene treatment and fresh-keeping mats mitigate peel browning and affect the aroma of Xinjiang “Yinggeer” flat peaches during cold storage

Food Chemistry: X
The current study explored the effects of 1-methylcyclopropene (1-MCP) and fresh-keeping mats (FKP) on aroma volatile levels and peel browning (PB) in flat peaches during.cold storage. Both 1-MCP and FKP treatments prevented PB by inhibiting the activity

Recent Advances of Polyphenol Oxidases in Plants

Molecules, 2023
Polyphenol oxidase (PPO) is present in most higher plants, but also in animals and fungi. PPO in plants had been summarized several years ago. However, recent advances in studies of PPO in plants are lacking. This review concludes new researches on PPO distribution, structure, molecular weights, optimal temperature, pH, and substrates.

Sex-related differences of two ecologically divergent Salix species in the responses of enzyme activities to atmospheric CO2 enrichment

Biologia Plantarum, 2013
Sex-related differences in the responses of plants to CO2 enrichment are still rarely studied. In this study, we examined the effects of elevated atmospheric CO2 (720 μmol mol-1) on the activities of polyphenoloxidases (PPOs) and guaiacol peroxidases ...

Intranasal Delivery of Gallium–Quercetin Nanoparticles for Multi‐Target Ferroptosis Inhibition in Parkinson's Disease

Advanced Science, EarlyView.
Leveraging the chemical similarity between Ga3+ and Fe3+ as well as the antioxidant properties of quercetin, gallium–quercetin nanoparticles (GQNPs) were prepared to integrate iron homeostasis regulation, oxidative stress suppression, and mitochondrial protection for multi‐target ferroptosis inhibition in Parkinson's Disease.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Pharmacokinetic Assessment of Atazanavir and Favipiravir Following Echinacea Supplementation: A Controlled Herb–Drug Interaction Investigation

Biopharmaceutics &Drug Disposition, EarlyView.
Pharmacokinetic interactions between Echinacea and two antiviral drugs, favipiravir and atazanavir, were assessed in rats. The findings suggest that Echinacea does not significantly affect the pharmacokinetics of favipiravir and atazanavir. These results provide preliminary evidence that concurrent use of Echinacea with these antiviral drugs may be ...
