Phylogenetic diversity in fim and mfa gene clusters between Porphyromonas gingivalis and Porphyromonas gulae, as a potential cause of host specificity

Journal of Oral Microbiology, 2020
Background Periodontopathic bacteria Porphyromonas gingivalis in humans and Porphyromonas gulae in animals are phylogenetically close and commonly have FimA and Mfa1 fimbriae.

Novel fimbrilin PGN_1808 in Porphyromonas gingivalis. [PDF]

PLoS ONE, 2017
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P.

Post-irradiation examinations of annular mixed oxide fuels with average burnup 4 and 5% FIMA

, 2020
We present post-irradiation examination results on two type of annular mixed oxide fuel pins irradiated in the Fast Flux Test Facility (FFTF) sodium cooled reactor to an average burnup between 4% and 5% fission of initial heavy atom (FIMA).

Adjuvant-driven epitope hierarchy correlates with the protective efficacy of FimA vaccine against Klebsiella pneumoniae

Frontiers in Immunology
Hypervirulent Klebsiella pneumoniae (hvKP) variants represent urgent multidrug-resistant threats against which no licensed vaccine exists. FimA is indispensable for KP mucosal colonization and is thus a promising vaccine target; however, its protective ...

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.

Role of SCFAs for Fimbrillin-Dependent Biofilm Formation of Actinomyces oris

Microorganisms, 2018
Actinomyces oris expresses type 1 and 2 fimbriae on the cell surface. Type 2 fimbriae mediate co-aggregation and biofilm formation and are composed of the shaft fimbrillin FimA and the tip fimbrillin FimB.

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

Digital fire technologies and community networks: Cultivating just sociotechnical practices for living with planetary change

People and Nature, EarlyView.
Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

Donor strand sequence, rather than donor strand orientation, determines the stability and non-equilibrium folding of the type 1 pilus subunit FimA

Journal of Biological Chemistry, 2020
FimA is the main structural subunit of adhesive type 1 pili from uropathogenic Escherichia coli strains. Up to 3000 copies of FimA assemble to the helical pilus rod through a mechanism termed donor strand complementation, in which the incomplete ...
