Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Gut Lactate Boosts Ruminococcus via Histone Lactylation to Mediate Time‐Restricted Feeding Protection in Crohn's Disease

open access: yesAdvanced Science, EarlyView.
TRF enriches Ruminococcus, a bacterial genus producing SCFAs, and activates the epithelial HIF‐1α signaling pathway. This mechanism protects the colonic mucosa from inflammatory insults in colitis models. Mechanistically, gut lactate production during starvation and refeeding mediates H4K12la, which increases SLC9A3 expression and creates an acidic gut

Novel Molecules for Intra-Oral Delivery of Antimicrobials to Prevent and Treat Oral Infectious Diseases [PDF]

open access: yes, 2008
New molecules were designed for efficient intra-oral delivery of antimicrobials to prevent and treat oral infection. The salivary statherin fragment, which has high affinity for the tooth enamel, was used as a carrier peptide. This was linked through the

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

open access: yesAdvanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

DOTA‐grafted Cationic Polymers Behaving as Powerful Macromolecular Resistance‐reversal Agents (MRRAs) Combating Against New Delhi Metallo‐β‐lactamase (NDM)‐producing Bacteria

open access: yesAdvanced Science, EarlyView.
Two macromolecular resistance‐reversal agents (MRRAs)—linear (MRRAL) and nanostructured (MRRAN) polymers were fabricated by integrating DOTA motifs into tunable polycationic scaffolds. MRRAs exhibit superior antibacterial potency once combined with meropenem (MEM) through (i) bacterial membrane disruption via localized cationic charge and ...

Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

open access: yesAdvanced Science, EarlyView.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...
