Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Association Between the Root Canal Microbiome and Apical Lesion Size: An Observational Shotgun Metagenomic Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...

Can Artificial Intelligence Be Utilised to Develop Point‐of‐Care Endodontic Microbiological Technologies?

International Endodontic Journal, EarlyView.
ABSTRACT Background Primary or persistent endodontic disease is caused by microbial biofilms that irritate the pulp and periapical tissues. Extensive microbiological analyses of these biofilms and their constituent pathogens have revealed their diversity and complexity.

Exploring the Impact of Ultrasonic Activation on the Antimicrobial Activity of Root Canal Sealers: A Year‐Long Ex Vivo Investigation Into Bacterial Survival

International Endodontic Journal, EarlyView.
ABSTRACT Aim This study investigated the long‐term survival of bacteria in root canals obturated using two endodontic sealers—AH Plus Jet (AHP) and BioRoot RCS (BCS)—while also assessing the influence of ultrasonic agitation on their antimicrobial effectiveness.

N2 fixation and ectomycorrhizal root enzyme activity are coupled on Siberian alder across an Arctic-boreal gradient

Environmental Research: Ecology
Siberian alder is a tall shrub expanding across Alaska. Host to ectomycorrhizal (EcM) fungi and nitrogen (N)-fixing actinobacteria, alder not only facilitates the addition of new N to its ecosystems through fixation, it may also alter phosphorus (P ...

L‐Glutamine Plus L‐Glutamic Acid Enhances Antioxidant Status and Ammonia Toxicity Resilience, Upregulates Interleukin IL‐10 Gene, and Improves Gut Microbiota and Survival in Juvenile Nile Tilapia

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Glutamine (Gln) and glutamic acid (Glu) are the most abundant free amino acids (AAs) in the fish body. Although classified as non‐essential AAs, their supplementation can be a strategy to optimize the growth performance and health of fish.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Periodontitis and Diabetes: Mechanistic Evidence of a Circular Relationship

Journal of Periodontal Research, EarlyView.
This narrative review aimed to explore the underlying mechanisms that connect periodontitis to diabetes (and vice versa) and that influence disease susceptibility, progression and response to treatment. ABSTRACT The circular relationship between periodontitis and diabetes mellitus is one of the most established oral‐systemic links.
