Gut Microbial Genetic Variation Prolongs Host Healthy Longevity and Remodels Metabolome and Proteome in Drosophila Melanogaster

Advanced Science, EarlyView.
This study reveals that specific genetic variations in gut‐residing Saccharomyces cerevisiae significantly extend healthspan and lifespan in Drosophila melanogaster. These mutants rejuvenate aged intestinal metabolism, upregulate mitochondrial proteins, and enhance energy pathways.

Dual‐Emission Carbon Dot Nanozymes Mitigate Salt Stress and Enhance Photosynthesis for Crop Germination and Growth

Advanced Science, EarlyView.
Dual‐emission carbon dot nanozymes are synthesized via microwave method. The nanozymes enhance photosynthesis corn seedlings through spectral‐matched light conversion. Their superoxide dismutase‐mimetic activity scavenges salt stress‐induced reactive oxygen species and circumvents energy‐intensive stress responses.

Rethinking the AI Paradigm for Solubility Prediction of Drug‑Like Compounds with Dual‐Perspective Modeling and Experimental Validation

Advanced Science, EarlyView.
Aqueous solubility governs drug delivery and bioavailability, yet its prediction remains challenging. Utilizing the largest curated dataset of drug‐like molecules, prediction models are constructed through dual‐perspective benchmarking. Stacking methods outperform advanced deep learning due to data constraints. These validated models enabled systematic

Riboflavin - properties, occurrence and its use in medicine

Pteridines, 2019
Riboflavin is built on an isoalloxazin ring, which contains three sixcarbon rings: benzoic, pyrazine and pyrimidine. Riboflavin is synthesized by some bacteria, but among humans and animals, the only source of flavin coenzymes (FAD, FMN) is exogenous ...

Biosynthesis of riboflavin: an unusual riboflavin synthase of Methanobacterium thermoautotrophicum [PDF]

Journal of Bacteriology, 1997
Riboflavin synthase was purified by a factor of about 1,500 from cell extract of Methanobacterium thermoautotrophicum. The enzyme had a specific activity of about 2,700 nmol mg(-1) h(-1) at 65 degrees C, which is relatively low compared to those of riboflavin synthases of eubacteria and yeast.

Dendrobium Officinale‐Derived Carbon Dots Nanozymes Alleviate Colitis by Orchestrating Intestinal Mucus‐Epithelium‐Immune Barriers

Advanced Science, EarlyView.
Dendrobium officinale‐derived carbon dots (DO‐CDs) exhibiting enzyme‐mimetic activities are synthesized via a hydrothermal approach. In the colitis model, DO‐CDs effectively facilitated the repair of mucosal, epithelial, and immune barriers by upregulating the expression of mucins and tight junction proteins, as well as re‐establishing intestinal ...
