Bioactive Polysaccharides Targeting Gut Microbiota to Modulate Host Health: A Gear Effect Theory

Food Frontiers, EarlyView.
The “Gear Effect” mechanism of bioactive polysaccharides driving gut microbiota to modulate host health. ABSTRACT Bioactive polysaccharides are macromolecular polymers with broad biological activities. Recent evidence has highlighted their role in modulating host health primarily through interactions with gut microbiota.

Combining nitrogen effects and metabolomics to reveal the response mechanisms to nitrogen stress and the potential for nitrogen reduction in maize

Journal of Integrative Agriculture, 2023
The physiological and metabolic differences in maize under different nitrogen (N) levels are the basis of reasonable N management, which is vital in improving fertilizer utilization and reducing environmental pollution.

Induction of resilience strategies against biochemical deteriorations prompted by severe cadmium stress in sunflower plant when Trichoderma and bacterial inoculation were used as biofertilizers

Frontiers in Plant Science, 2022
BackgroundCadmium (Cd) is a highly toxic heavy metal. Its emission is suspected to be further increased due to the dramatic application of ash to agricultural soils and newly reclaimed ones. Thereby, Cd stress encountered by plants will exacerbate. Acute

Multi‐Omics Analysis of Ileal Mucosa and Mesentery Before and After Ileocecal Resection in Crohn's Disease

United European Gastroenterology Journal, EarlyView.
ABSTRACT Crohn's disease (CD), a type of inflammatory bowel disease (IBD), is a chronic disorder involving any part of the gastrointestinal tract. Ileocecal resection may serve as a more effective treatment option for early CD. However, the potential relationship and mechanisms between the ileocecum and remission induction of CD are still elusive.

Aged Gut Microbiota Contributes to Cognitive Impairment and Hippocampal Synapse Loss in Mice

Aging Cell, EarlyView.
Li et al. revealed that aged gut microbiota induces cognitive decline and microglia‐mediated synapse loss. Fecal Bifidobacterium pseudolongum abundance was reduced in patients with cognitive impairment and microbiota transplantation from patients with fewer B.p abundance yielded worse cognitive behavior in mice.

Tryptophan-centered metabolic alterations coincides with lipid-mediated fungal response to cold stress

Heliyon, 2023
Tryptophan and its derived metabolites have been assumed to play important roles in the development and survival of organisms. However, the links of tryptophan and its derived metabolites to temperature change remained largely cryptic.

Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

Immunology, EarlyView.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

Synthesis of new indolecarboxylic acids related to the plant hormone indoleacetic acid IAA

Journal of the Brazilian Chemical Society, 2003
The synthesis of 5,6-methylenedioxy-indol-3-yl-methanoic acid 8 and 5,6-methylenedioxy-indol-3-yl-acetic acid 13 is described. Piperonal was employed as starting material, and the construction of the heterocyclic ring based on the Hemetsberger reaction ...

Evidence for Two Indoleacetic Acid-Induced Growth Responses in the Avena Straight-Growth Indoleacetic Acid Assay [PDF]

Plant Physiology, 1993
Floating Avena sativa L. cv Victory coleoptile segments were used to determine whether the straight-growth indoleacetic acid (IAA) assay can be reconciled with the Avena curvature assay and the Cholodny-Went theory of photo- and gravitropism. Measurements of segment length after 5 h yield sigmoid-shaped IAA dose-response curves with the growth rate ...

Shaping Plant Growth Beneath the Soil: A Theoretical Exploration of Fungal Endophyte's Role as Plant Growth‐Promoting Agents

MicrobiologyOpen, Volume 14, Issue 4, August 2025.
A schematic representation depicting various mechanisms of plant growth promotion by fungal endophytes present in different parts of the plant. Fungal endophytes are present in various parts of the plant, including leaves, stems, and most abundantly in roots.
