Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

A new class of marine Euryarchaeota group II from the mediterranean deep chlorophyll maximum [PDF]

The ISME Journal, 2014
Abstract We have analyzed metagenomic fosmid clones from the deep chlorophyll maximum (DCM), which, by genomic parameters, correspond to the 16S ribosomal RNA (rRNA)-defined marine Euryarchaeota group IIB (MGIIB). The fosmid collections associated with this group add up to 4 Mb and correspond to at least two species within this group.

Phylogenetic Diversity of Archaea in Shallow Hydrothermal Vents of Eolian Islands, Italy

Diversity, 2019
Shallow hydrothermal systems (SHS) around the Eolian Islands (Italy), related to both active and extinct volcanism, are characterized by high temperatures, high concentrations of CO2 and H2S, and low pH, prohibitive for the majority of eukaryotes which ...

Kefir: A Potential Gut Microbiota Modulator: A Systematic Review of Human Interventional Studies

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Daily cow's milk kefir intake transiently enriches gut microbiota, modulates the intestinal environment by increasing SCFA and reducing pH and oxygen, and exerts antimicrobial effects via SCFAs, bacteriocins, exopolysaccharides, and microbial fractions, highlighting its potential for gut health promotion.

Gut Microbiota as a Key Modulator in the Pathophysiology of Sepsis: SURVEIL Project

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Longitudinal profiling of 132 hospitalized patients reveals that age, colonization status, and sepsis interact to shape gut microbiota diversity and composition. Sepsis is associated with reduced alpha diversity, beta‐diversity shifts, functional predictions (methanogenesis, nitrate/sulfate respiration), and partial MDR overlap with bloodstream ...

Archaeal tRNA-Splicing Endonuclease as an Effector for RNA Recombination and Novel Trans-Splicing Pathways in Eukaryotes

Journal of Fungi, 2021
We have characterized a homodimeric tRNA endonuclease from the euryarchaeota Ferroplasma acidarmanus (FERAC), a facultative anaerobe which can grow at temperatures ranging from 35 to 42 °C. This enzyme, contrary to the eukaryal tRNA endonucleases and the

Whole-proteome tree of life suggests a deep burst of organism diversity. [PDF]

, 2020
An organism tree of life (organism ToL) is a conceptual and metaphorical tree to capture a simplified narrative of the evolutionary course and kinship among the extant organisms.

Exploring the Gut‐Prostate Axis: Microbial Signatures Linked to Prostate Volume and Bladder Function

The Prostate, Volume 86, Issue 8, Page 900-910, June 2026.
ABSTRACT Background Benign prostatic hyperplasia (BPH) is a common urologic condition in aging men, often linked to systemic inflammation and metabolic dysfunction. Emerging evidence suggests that the gut microbiome may contribute to prostate health and disease.

Extracellular vesicle formation in Euryarchaeota is driven by a small GTPase

Proceedings of the National Academy of Sciences
Since their discovery, extracellular vesicles (EVs) have changed our view on how organisms interact with their extracellular world. EVs are able to traffic a diverse array of molecules across different species and even domains, facilitating numerous functions. In this study, we investigate EV production in Euryarchaeota,

Effect of hay supplementation timing on rumen microbiota in suckling calves

MicrobiologyOpen, 2018
An animal feeding trial was conducted on 18 seven‐day‐old Holstein dairy bull calves weighing 42 ± 3 kg each. Calves were randomly assigned into three groups (n = 6 each). The dietary treatments were as follows: (1) milk and starter for the control group
