Light‐Activated Ruthenium Nanoclusters Reprogram the Metabolic‐Quorum Sensing Axis for Precision Periodontitis Therapy

Advanced Science, EarlyView.
Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

Synthesis of purines and adenines containing the hexafluoroisopropyl group

Beilstein Journal of Organic Chemistry, 2020
Several new derivatives of adenine, purine, and theophylline containing the (CF3)2CH group connected to a nitrogen atom of the imidazole ring were prepared by the reaction of 2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithietane (1) with the corresponding ...

Metabolic basis for disorders of purine nucleotide degradation

, 1981
Purine nucleotide degradation refers to a regulated series of reactions by which human purine ribonucleotides and deoxyribonucleotides are degraded to uric acid in humans. Two major types of disorders occur in this pathway.

Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Probiotics in Alleviating Hyperuricemia: Research Status, Mechanism of Action and Challenges

Shipin gongye ke-ji
Hyperuricemia (HUA) is a chronic metabolic disease, characterized by excessive uric acid in the blood, caused by purine metabolism disorders. Studies show that conventional clinical treatment methods have certain limitations, while probiotics have the ...

Eine Universelle Nukleosid‐zu‐Nukleosid‐5′‐triphosphat‐Enzymkaskade angetrieben durch Polyphosphat

Angewandte Chemie, EarlyView.
Nukleosid‐5′‐Triphosphate (NTPs) sind wichtige Bausteine für Nukleinsäuren. Ihre chemische Synthese ist aufgrund der geringen Ausbeute der 5′‐Triphosphorylierungsreaktion nur wenig effizient. Wir stellen hier eine universelle, durch Polyphosphat angetriebene Zwei‐Enzym‐Kaskade vor, die eine direkte Phosphorylierung von Nukleosiden zu NTPs ermöglicht ...
