Disrupting Helicobacter pylori Iron Homeostasis With Bismuth Nanodrug‐Mediated Nutritional Trap for Targeted Gastric Infection Therapy

Advanced Science, EarlyView.
A “nutritional trap” strategy centered on disrupting bacterial iron homeostasis is proposed. The synthesized Bi‐TP@FU (TBF) can target Helicobacter pylori, interfere with the bacterial iron uptake and utilization processes to disrupt its iron homeostasis, induce bacterial death, and meanwhile preserve the balance of the intestinal flora.

Cell-Cell Signaling Proteobacterial LuxR Solos: a Treasure Trove of Subgroups Having Different Origins, Ligands, and Ecological Roles

mSystems, 2023
Many proteobacteria possess LuxR solos which are quorum sensing LuxR-type regulators that are not paired with a cognate LuxI-type synthase. LuxR solos have been implicated in intraspecies, interspecies, and interkingdom communication by sensing ...

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

Advanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

IBD—what role do proteobacteria play?

, 2012
The gastrointestinal microbiota has come to the fore in the search for the causes of IBD. This shift has largely been driven by the finding of genetic polymorphisms involved in gastrointestinal innate immunity (particularly polymorphisms in NOD2 and ...

The potential role of gut microbiota in the occurrence and development of endometriosis

Frontiers in Cellular and Infection Microbiology
Endometriosis (EMT) has a significant impact on women’s physical and mental health. In this study, high-throughput sequencing technology was employed to detect differences in gut microbiota between EMT patients and healthy individuals (CTL). Additionally,

Gut‐Liver Translocation of Bacteroides Uniformis Alleviates Advanced Metabolic Dysfunction‐Associated Steatotic Liver Disease by Suppressing Hepatocyte Ferroptosis via Propionic Acid Secretion

Advanced Science, EarlyView.
Systematic characterization of the liver‐resident microbiota in advanced metabolic dysfunction‐associated steatotic liver disease (MASLD) reveals a consistent depletion of Bacteroides uniformis (B. uniformis) in both hepatic and gut microbial communities. Oral gavage of B.

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

Advanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

Oral Nanomicelle‐Mediated Sequential Butyrate Production in the Intestine for Ulcerative Colitis and Immunosuppression Treatment

Advanced Science, EarlyView.
After oral administration, inodorous GLU‐BA self‐assembles into nanomicelles in aqueous environments to resist premature gastric adsorption. Upon reaching the intestine, endogenous esterases rapidly cleave the built‐in ester bonds in these nanomicelles to release BA and GLU, with GLU further metabolized by gut microbiota to gradually generate BA ...
