Comparison and reliability assessment of CO2 quantification methods for carbonated cementitious materials

Journal of CO2 Utilization
Various CO2-absorbing concretes have been developed; however, an accurate assessment of their CO2 content is critically important. CO2 has been quantified by releasing it from concrete and measuring the sample mass loss and/or the released CO2; however ...

Environmental Stress Induces Altered Composition of Streptococcus mutans Membrane Vesicles: pH‐Driven Changes in Membrane Vesicle Production and Composition

Molecular Oral Microbiology, EarlyView.
ABSTRACT Bacteria produce membrane vesicles (MVs) in response to environmental stress and genetic changes. Previous studies have shown that MVs can trigger inflammatory responses and may serve as important mediators of host–microbe interactions. Given the dynamic nature of the oral microbiome, bacteria such as Streptococcus mutans are frequently ...

First synoptic analysis of volcanic degassing in Papua New Guinea [PDF]

We report the first satellite-based survey of volcanic sulphur dioxide (SO2) degassing in Papua New Guinea, using Ozone Monitoring Instrument (OMI) data. OMI is sensitive to low-level passive degassing.

Random Mutagenesis in Porphyromonas gingivalis Enables Isolation of Mutants With Enhanced Secreted Protease Activity

Molecular Oral Microbiology, EarlyView.
ABSTRACT Porphyromonas gingivalis is a key pathogen in periodontitis, with secreted proteases as major virulence factors. We developed a screening method to generate and identify P. gingivalis mutants with elevated protease activity. Mutations were induced using the mutagens 2,6‐diaminopurine (2,6‐DAP) or ethyl methanesulfonate (EMS), and the ...

Porphyromonas gingivalis Outer Membrane Vesicles‐Associated DNA Triggers Inflammation by Inducing IL‐6 in Astrocytes

Molecular Oral Microbiology, EarlyView.
Pg releases OMVs which contain Pg genomic DNA. The Pg OMVs‐associated DNA is incorporated into astrocytes via endocytosis and increases IL‐6 mRNA expression via TLR9. These effects of Pg OMVs may induce neuroinflammation, which could contribute to the onset and progression of AD in periodontal disease.

Omi/HtrA2 Protease Associated Cell Apoptosis Participates in Blood-Brain Barrier Dysfunction

Frontiers in Molecular Neuroscience, 2019
Background: Omi/HtrA2 is a proapoptotic mitochondrial serine protease involved in caspase-dependent cell apoptosis, translocating from mitochondria to the cytosol after an apoptotic insult.
