Isolation and characterization of a novel human intestinal Enterococcus faecium FUA027 capable of producing urolithin A from ellagic acid

Frontiers in Nutrition, 2022
Urolithin A (UA) has received considerable research attention because of its health benefits. However, only a few strains have been reported to produce UA from ellagic acid (EA), and the molecular mechanisms underlying the gut microbiota-mediated ...

Selective autophagy pathways in ageing and neurodegeneration: Emerging roles for mitophagy and nucleophagy

The FEBS Journal, EarlyView.
As we age, cells gradually accumulate damage, which can contribute to disease and neurodegeneration. This review explores how two cellular recycling processes, mitophagy and nucleophagy, remove damaged mitochondria and nuclear material, respectively, to maintain cell health and long‐term neuronal homeostasis.

Himalayan Asphaltum-Driven Synthesis of Gold and Selenium Nanoparticles: Investigation of Antimicrobial Activity and Urolithin Levels

Molecules
This work examines the utilization of the natural product shilajit resin, sourced from the Himalayas, for the extraction of diverse components suitable to the synthesis of gold nanoparticles (AuNPs) and selenium nanoparticles (SeNPs). The study evaluated

Urolithin A Is a Dietary Microbiota-Derived Human Aryl Hydrocarbon Receptor Antagonist

Metabolites, 2018
Urolithins (e.g., UroA and B) are gut microbiota-derived metabolites of the natural polyphenol ellagic acid. Urolithins are associated with various health benefits, including attenuation of inflammatory signaling, anti-cancer effects and repression of ...

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

In vitro conversion of ellagic acid to urolithin A by different gut microbiota of urolithin metabotype A

Applied Microbiology and Biotechnology
Abstract The metabolite urolithin A, a metabolite of the dietary polyphenol ellagic acid (EA), has significant health benefits for humans. However, studies on the gut microbiota involved in ellagic acid metabolism are limited.

In vivo administration of gut bacterial consortia replicates urolithin metabotypes A and B in a non-urolithin-producing rat model

Food & Function, 2023
The two bacterial consortia colonized the intestine of rats and converted UM-0 (non-urolithin-producing) animals into urolithin-producing animals mimicking the UM-A and UM-B metabotypes.

Identifying Brazilwood’s Marker Component, Urolithin C, in Historical Textiles by Surface-Enhanced Raman Spectroscopy

Heritage, 2021
The fugitive nature of the colorants obtained from sappanwood (Caesalpinia sappan L.) or the South American species commonly known as ‘brazilwoods’ (including other Caesalpinia species and Paubrasilia echinata (Lam.)) makes the identification of ...

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

Experimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

Metabolomics Insights Into Nutritional Intervention With Polyphenols in Feedlot Beef Cattle

New Zealand Journal of Agricultural Research, Volume 69, Issue 6, December 2026.
Polyphenol‐based feed additives have been increasingly used in feedlot diets due to their potential to modulate rumen fermentation and systemic redox and inflammatory responses; however, mechanistic evidence at the systemic level in finishing cattle remains limited.
