New techniques to characterise the vaginal microbiome in pregnancy [PDF]

open access: yes, 2016
Understanding of the vaginal microbiome in health and disease is essential to screen, detect and manage complications in pregnancy. One of the major complications of pregnancy is preterm birth, which is the leading world-wide cause of death and ...

Alistipes senegalensis is Critically Involved in Gut Barrier Repair Mediated by Panax Ginseng Neutral Polysaccharides in Aged Mice

open access: yesAdvanced Science, EarlyView.
An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

Bacteroides Fragilis‐Derived Outer Membrane Vesicles Deliver MiR‐5119 and Alleviate Colitis by Targeting PD‐L1 to Inhibit GSDMD‐Mediated Neutrophil Extracellular Trap Formation

open access: yesAdvanced Science, EarlyView.
Bacteroides fragilis‐derived outer membrane vesicles deliver miR‐5119 and alleviate colitis by targeting PD‐L1 to inhibit GSDMD‐mediated neutrophil extracellular trap formation. Abstract Inflammatory bowel disease (IBD) results from a breakdown in the symbiotic relationship between the intestinal commensal microflora and the mucosal immune system.

Vaginal microbiota signatures in healthy and purulent vulvar discharge sows

open access: yesScientific Reports, 2022
Purulent vulvar discharges, primarily caused by genito-urinary tract infections, are an important source of economic loss for swine producers due to sow culling and mortality.

Mechanistic Foundations of KRAS‐Driven Tumor Ecosystems: Integrating Crosstalk among Immune, Metabolic, Microbial, and Stromal Microenvironment

open access: yesAdvanced Science, EarlyView.
KRAS mutations dynamically remodel the tumor microenvironment (TME), fostering immunosuppression, metabolic symbiosis, and stromal plasticity. This review dissects how oncogenic KRAS variants sculpt TME networks and explores actionable vulnerabilities. Emerging strategies combining KRAS inhibitors and TME‐editing approaches offer potential to dismantle

Anaerobic bacteria growth in the presence of cathelicidin LL-37 and selected ceragenins delivered as magnetic nanoparticles cargo

open access: yesBMC Microbiology, 2017
Background Cationic antibacterial peptides (CAPs) and synthetic molecules mimicking the amphiphilic structure of CAPs, such as ceragenins, are promising compounds for the development of new antimicrobials.

Diagnosis of Bacteroides fragilis infection with counter-immunoelectrophoresis. [PDF]

open access: yesJournal of Clinical Pathology, 1978
In a study of 188 patients and 109 controls, the detection of antibody by counterimmunoelectrophoresis was used as a diagnostic aid in human infections with Bacteroides fragilis. It was found that positive results indicated current infection and negative results were not conclusive.

Porphyromonas gingivalis periodontal infection and its putative links with Alzheimer’s disease [PDF]

open access: yes, 2015
Periodontal disease (PD) and Alzheimer’s disease (AD) are inflammatory conditions affecting the global adult population. In the pathogenesis of PD, subgingival complex bacterial biofilm induces inflammation that leads to connective tissue degradation and

A Novel nor@DHB Matrix for Direct Microbial Analysis in Lung Cancer Tissues

open access: yesAdvanced Science, EarlyView.
Integrated matrix‐assisted laser desorption/ionization mass spectrometry workflow quantifies intratumoral microbes in lung cancer through lipopolysaccharide/lipid A extraction from biopsies. The novel ionic matrix called norharmane conjugated to 2,5‐dihydroxybenzoic acid enhances lipid A ionization, enabling direct detection of bacterial genera ...
