Queuosine (Q), a 7-deazaguanosine derivative, is among the most intricate tRNA modifications, and located at position 34 (the Wobble position) of tRNAs with GUN anticodon. Found in eukaryotes many bacteria, Q unique modifications because its full biosynthetic pathway exists only bacteria. In contrast, are auxotrophic for Q, relying on dietary sources gut microbiota to acquire nucleobase queuine. This dependency creates nutritional link translation host. enhances base pairing U helps balance translational speed between codons ending C eukaryotes.

The factors shaping human microbiome variation are a major focus of biomedical research. While other fields have used large sequencing compendia to extract insights requiring otherwise impractical sample sizes, the field has lacked comparably sized resource for 16S rRNA gene amplicon commonly quantify composition. To address this gap, we processed 168,464 publicly available gut samples with uniform pipeline. We use compendium evaluate geographic and technical effects on variation. find that regions such as Central Southern Asia differ significantly from more thoroughly characterized microbiomes Europe Northern America composition alone can be predict sample's region origin. also strong associations between primers DNA extraction. anticipate growing work, Human Microbiome Compendium, will enable advanced applied methodological

The complex relationship between diet, the gut microbiota, and mental health, particularly depression, has become a focal point of contemporary research. This critical review examines how specific dietary components, such as fiber, proteins, fats, vitamins, minerals, bioactive compounds, shape microbiome influence microbial metabolism in order to regulate depressive outcomes. These dietary-induced changes microbiota can modulate production metabolites, which play vital roles gut–brain communication. axis facilitates this communication through neural, immune, endocrine pathways. Alterations metabolites central nervous system (CNS) functions by impacting neuroplasticity, inflammatory responses, neurotransmitter levels—all are linked onset course depression. highlights recent findings linking components with beneficial composition reduced symptoms. We also explore challenges individual variability responses interventions long-term sustainability these strategies. underscores necessity for further longitudinal mechanistic studies elucidate precise mechanisms diet interactions be leveraged mitigate paving way personalized nutritional therapies.

The purpose of this article is to present selected food additives as disruptors normal intestinal homeostasis with a potential impact on the development metabolic dysfunction-associated steatotic liver disease (MASLD). A comprehensive literature search was conducted in three major electronic databases: PubMed, ScienceDirect, and Google Scholar. MASLD prevalent condition that closely related global rise obesity. Its pathogenesis multifactorial, genetic, environmental, factors playing key role. “multiple-hit” hypothesis suggests Western-style diet, rich ultra-processed foods, saturated fats, additives, combined low physical activity, contributes obesity, which promotes lipid accumulation liver. Recent studies underscore role impaired MASLD. Food including preservatives, emulsifiers, sweeteners, affect gut health function. Selected preservatives inhibit pathogenic microorganisms but disrupt microbiota, leading changes permeability dysfunction.
