Purification and characterization of a novel secondary fimbrial protein from Porphyromonas gulae

Journal of Oral Microbiology, 2012
Background: Porphyromonas gulae are black-pigmented anaerobic bacteria isolated from the gingival sulcus of various animal hosts and are distinct from Porphyromonas gingivalis originating in humans. We previously reported the antigenic similarities of 41-

Porphyromonas gingivalis FimA fimbriae: fimbrial assembly by fimA alone in the fim gene cluster and differential antigenicity among fimA genotypes. [PDF]

PLoS ONE, 2012
The periodontal pathogen Porphyromonas gingivalis colonizes largely through FimA fimbriae, composed of polymerized FimA encoded by fimA. fimA exists as a single copy within the fim gene cluster (fim cluster), which consists of seven genes: fimX, pgmA and

Modeling Multiscale Architecture of Biofilm Extracellular Matrix and Its Role in Oxygen Transport

Biotechnology and Bioengineering, EarlyView.
Conceptual ‘resistance‐in‐series' model using cell‐capsule approach is introduced to investigate oxygen transport in the extracellular matrix. Bacterial capsule as a separate, distinct feature from the bulk EPS is the main focus of our present study. ABSTRACT The extracellular polymeric substances (EPS) matrix of microbial biofilms exhibits a complex ...

Transcriptional Profiling of a Cross-Protective Salmonella enterica serovar Typhimurium UK-1 dam Mutant Identifies a Set of Genes More Transcriptionally Active Compared to Wild-Type, and Stably Transcribed across Biologically Relevant Microenvironments

Pathogens, 2014
Vaccination with Salmonella enterica serovar Typhimurium lacking DNA adenine methyltransferase confers cross-protective immunity against multiple Salmonella serotypes. The mechanistic basis is thought to be associated with the de-repression of genes that

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Long‐Term Blood Pressure Variability, Hippocampal Subfield Volume and Cognitive Decline: A Population‐Based Prospective MRI Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐term blood pressure variability (BPV) is associated with cognitive decline, yet the underlying mechanisms have not been fully elucidated. Purpose To investigate the associations between long‐term BPV and hippocampal subfield volume and cognitive function and to assess the mediation effect of hippocampal subfield volume.
