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.

Inner-membrane protein MorC is involved in fimbriae production and biofilm formation in Aggregatibacter actinomycetemcomitans

Microbiology, 2016
Fimbrial subunit synthesis, secretion and assembly on the surface of the periodontal pathogen Aggregatibacter actinomycetemcomitans are essential for biofilm formation. A recent quantitative proteomics study employing an afimbriated strain and a developed mutant isogenic for the inner-membrane protein morphogenesis protein C (MorC) revealed that the ...

Pasteurella lipoprotein E interacts with host ABCF2 to facilitate adhesion and cell apoptosis

mLife, EarlyView.
Abstract Pasteurella multocida can cause serious diseases in many animal species and humans, yet the mechanisms of its pathogenesis remain to be elucidated. In this study, we found that the lipoprotein E (PlpE) of P. multocida contributed to bacterial adhesion to host cells.

Interaction of Fimbriae of Haemophilus influenzae Type B with Heparin-Binding Extracellular Matrix Proteins [PDF]

Infection and Immunity, 2000
ABSTRACT The interaction of the fimbriae of Haemophilus influenzae type b (Hib) with two heparin-binding extracellular matrix proteins, human fibronectin (Fn) and heparin-binding growth-associated molecule (HB-GAM) from mouse, were studied.

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
