An atlas of colonization factors in the mouse gut microbiome reveals phylogenetically structured repertoires and infection-stage-associated variation during Toxoplasma gondii infection in mice

ABSTRACT Colonization factors (CFs) comprise CF-associated gene families related to microbial establishment, persistence, host interaction, and gut ecological fitness, but their organization and variation in the mouse gut microbiome remain poorly defined. We integrated the Mouse...

Genome-resolved analysis reveals disruption of gut microbial vitamin B and K 2 biosynthesis during Toxoplasma gondii infection in mice

ABSTRACT Toxoplasma gondii infection remodels the gut microbiome, yet its impact on microbial vitamin biosynthetic potential and host redox metabolism remains unclear. Here, we integrated mouse gut metagenomes with publicly available metagenome-assembled genomes (MAGs) to constru...

Potential Ameliorative Effect of Aged Liubao Tea Aqueous Extract on D-Galactose-Induced Pathological Damage in an Alzheimer’s Disease Zebrafish Model

Background: Alzheimer’s disease (AD) is a prevalent neurodegenerative disorder for which effective treatments remain limited. Liubao tea, a distinctive post-fermented dark tea, develops unique aged and areca nut aromas through prolonged storage. However, comprehensive studies on...

Erdős–Graham Problem #411 – A Construction of Six Solution Families for the r=2 Case

We construct and verify six infinite families of solutions to the r=2 case of the Erdős–Graham iteration problem (Problem #411). Steinerberger [1] reduced the r=2 case to the equation φ(n) + φ(n+φ(n)) = n and proved that any solution must fall into one of two branches: either the...

Chemical Diversity and Microbial Complexity of Liupao Tea Aroma: A Comprehensive Review

Liupao tea (LPT), one of China’s representative fermented dark teas, develops its unique “red, heavy, aged, and mellow” flavor characteristics. This review provides a comprehensive update on LPT aroma, integrating analyses of volatile organic compounds (VOCs), associated microorg...

Erdős–Graham Problem #411– A Complete Proof of the r=2 Case via the UF Framework

We present a complete proof of the r=2 case of the Erdős–Graham iteration problem (Problem #411). Steinerberger (2025) reduced this case to the equation phi(n) + phi(n + phi(n)) = n, finding six solution families and showing any additional solution must be of the form n = 2^a p^b...

The UF Operator – Definition, Construction, and Boundaries

This paper defines the UF operator (Unrestricted Function) as a new algebraic framework for implicit domain restriction. The operator allows functions to be written without explicit conditional statements by embedding domain restrictions into the algebraic structure via a formal...
