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 ...

Kinetic analysis of the synthesis and assembly of type 1 fimbriae of Escherichia coli [PDF]

Journal of Bacteriology, 1984
The adhesive organelles (type 1 fimbriae) of K-12 and other isolates of Escherichia coli are composed of identical 17,000-dalton subunits. We examined the assembly of these subunits into fimbrial organelles. After synthesis, the nascent subunits were first processed and then assembled into the organelles; the assembly step took almost 3 min in log ...

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.

Comparison of Escherichia coli fimbrial antigen F7 with type 1 fimbriae [PDF]

Infection and Immunity, 1980
Two Escherichia coli O6:K2:H1 strains, C1212 and C1214, isolated from urinary tract infections, were compared for their capacity to adhere to various cells. After growth on solid medium, only C1212 bacteria agglutinate human erythrocytes and attach to urinary epithelial cells. Both of these reactions are mannose resistant.

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.

Immunoelectron microscopic analysis of elongation of type 1 fimbriae in Escherichia coli [PDF]

Journal of Bacteriology, 1987
Using 10- and 20-nm-diameter gold particles conjugated to an antifimbrial monoclonal antibody, we analyzed the location of assembly of newly formed subunits on growing type 1 fimbriae of Escherichia coli. Fimbriae were removed from an E. coli K-12-derived strain, CSH50, by blending.

A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)

Nordic Journal of Botany, EarlyView.
Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.

Salmonella adhesion is decreased by hypoxia due to adhesion and motility structure crosstalk

Veterinary Research, 2023
Initial stages of Salmonella Typhimurium infection involve a series of coordinated events aimed at reaching, attaching to, and invading host cells. Virulence factors such as flagella, fimbriae, and secretion systems play crucial roles in these events and

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.
