Differential expression and adherence of Porphyromonas gingivalis FimA genotypes [PDF]

Molecular Oral Microbiology, 2011
SummaryPorphyromonas gingivalis is a primary pathogen involved in the initiation and progression of adult chronic periodontitis. Its colonization on oral surfaces is a necessary first step leading to infection. FimA, a subunit protein of major (long) fimbriae, is a well‐known virulence factor.

The Subgingival Host–Microbial Landscape in Mothers With Periodontitis and Their At‐Risk Offspring

Journal of Clinical Periodontology, Volume 53, Issue 2, Page 201-213, February 2026.
ABSTRACT Aim To evaluate the subgingival proteome and microbiome of mothers with periodontitis and their offspring, thereby assessing signatures of periodontal diseases. Methods Forty participants in four groups were included: mothers with periodontitis and their offspring, as well as periodontally healthy mothers and their offspring.

Milk protein-based formulas containing different oils affect fatty acids balance in term infants: A randomized blinded crossover clinical trial

Lipids in Health and Disease, 2017
Background Palm olein is used in infant formula fat blends in order to match the fatty acid profile of human milk. While the effects on fatty acid balance have been evaluated, the use of palm olein in combination with palm kernel oil and supplementation ...

Salivary Porphyromonas gingivalis predicts outcome in oral squamous cell carcinomas: a cohort study

BMC Oral Health, 2021
Background Studies suggest Porphyromonas gingivalis (Pg) increased the incidence of oral squamous cell carcinoma (OSCC). However, fimA genotypes distribution of Pg, the origination of Pg in tissue, and its prognostic value are inconclusive.

Colistin and Biofilm‐Related Genes of Positive Escherichia coli O157:H7 in Cattle (Bos taurus) Carcasses Antibiotic Resistance Profiles, Biofilm and Molecular Characterisation of Isolates

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Antimicrobial resistance in various infectious agents poses a public health threat. Therefore, this study aimed to determine the antibiotic resistance profiles, biofilm formation abilities and molecular characterisation of colistin‐resistant Escherichia coli O157:H7 from cattle carcasses.

New cases of δ‐aminolevulinic acid dehydratase deficiency: Functional insights into gene variants using an innovative mouse liver model

Journal of Internal Medicine, Volume 299, Issue 1, Page 126-142, January 2026.
Abstract Background Dysfunction of δ‐aminolevulinic acid dehydratase (ALAD), the second enzyme involved in heme biosynthesis, leads to two pathologies: genetic and acquired. The genetic form is an ultrarare, severe childhood‐onset disease inherited in an autosomal recessive manner, whereas the acquired form usually affects adults due to enzyme ...

An Engineered Probiotic Consortium Based on Quorum‐Sensing for Colorectal Cancer Immunotherapy

Advanced Science, Volume 12, Issue 46, December 11, 2025.
This work develops an engineered probiotic consortium sensing pH, hypoxia, and lactate in the tumor microenvironment. It releases a lactate‐depleting enzyme (LdhA) and a PD‐L1 nanobody. In humanized mouse models (MC38 and HT‐29 tumors), it achieves durable oscillations, suppresses tumors, activates CD8+, CD4+, IFN‐γ+ T cells, and reduces Foxp3 ...

Cloning and expression of FimA-c3d recombinant protein

Journal of Genetic Engineering and Biotechnology, 2014
AbstractRecombinant protein consisting of an antigen fused to C3d may elicit a more robust immune response than the antigen alone. The objective of the present study was to clone FimA-c3d recombinant DNA into pCold-TF vector and successfully express in prokaryotic expression vector.

Régénération des huiles lubrifiantes usagées par processus de traitement à l’acide

Revue des Énergies Renouvelables, 2014
Les huiles sont obtenues par distillation des produits lourds du pétrole. Avec la baisse de la production de réserves mondiales de pétrole, la nécessité se pose plus que jamais, de recycler des huiles lubrifiantes usagées.

Fimbriae‐Targeted Peptide‐Selenoviologen Cyclophane Complex for Enhanced Photodynamic Therapy of Periodontitis

Aggregate, Volume 6, Issue 12, December 2025.
This study develops a supramolecular photosensitizer (SeVB⊃PQ) by combining SeVB with a P. gingivalis‐targeting peptide. SeVB⊃PQ selectively binds P. gingivalis, boosts ROS generation under irradiation, disrupts ATP synthesis, restores microbial balance, reduces inflammation, and promotes alveolar bone regeneration, offering a promising platform for ...
