Bacterial biofilms use chiral branches to escape crowded environments by tracking oxygen gradient [PDF]

arXiv, 2022
Bacterial biofilms collectively develop distinct and ordered structures, including fibers, bundles, and branches. Often, it is unclear how these structural motifs convey specific advantages to bacterial strains under challenging conditions. In oxygen-limited environments, dense bacterial aggregates generally deplete oxygen, which leads to arrest of ...

Effects of a 4‐week free‐sugar avoidance during periodontal therapy: An explorative randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background This study investigated the effect of a 4‐week free‐sugar avoidance on periodontal parameters during periodontal therapy. Methods Twenty‐one patients with untreated periodontitis and daily free‐sugar intake were allocated to a sugar avoidance group (SAG) and a control group (CG).

Rheology of bacterial suspensions under confinement [PDF]

arXiv, 2019
As a paradigmatic model of active fluids, bacterial suspensions show intriguing rheological responses drastically different from their counterpart colloidal suspensions. Although the flow of bulk bacterial suspensions has been extensively studied, the rheology of bacterial suspensions under confinement has not been experimentally explored.

Effects of bacterial density on growth rate and characteristics of microbial-induced CaCO3 precipitates: a particle-scale experimental study [PDF]

arXiv, 2020
Microbial-Induced Carbonate Precipitation (MICP) has been explored for more than a decade as a promising soil improvement technique. However, it is still challenging to predict and control the growth rate and characteristics of CaCO3 precipitates, which directly affect the engineering performance of MICP-treated soils.

Efficacy of microbial cell‐free DNA testing for detecting pathogens in pediatric patients with head and neck infections—An initial study

Pediatric Investigation, EarlyView.
We investigate the utility of microbial cell‐free DNA (mcfDNA) from the blood to predict surgical culture results. In this study, only 26.9% of patients had mcfDNA results that were considered predictive of the causative organism(s). There was a significant burden of contamination in the cohort, emphasizing that dedicated protocols must be followed ...

PET-scan in diagnosis of non-bacterial thrombotic endocarditis: a case report

The Egyptian Heart Journal
Background Non-bacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis or Libman–Sacks endocarditis, is a rare non-infectious condition affecting mostly the left-sided heart valves of patients who, most often, suffer from ...

Investigation of antibacterial, antifungal, and antioxidant activities in novel poly(DEAEMA‐co‐EMA)/polyindole composites

Polymer Engineering &Science, EarlyView.
Schematic illustration of prepared poly(DEAEMA‐co‐EMA)/PIN composities and 3D AFM image. Abstract In the current study, in the first stage, amphiphilic poly(2‐diethylamino ethylmethacrylate‐co‐ethyl methacrylate) [Poly(DEAEMA‐co‐EMA)] was synthesized from the 2‐diethylamino ethylmethacrylate (DEAEMA) and the ethyl methacrylate (EMA) using the free ...

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

A mitochondria‐targeted aggregation‐induced emission photosensitizer for eradication Candida biofilms and treating oral ulcer

Smart Molecules, EarlyView.
A mitochondria‐targeted AIE photosensitizer, LIQ‐TPA‐TZ, was developed to fight against Candida infection. It can efficiently produce reactive oxygen species to kill Candida guilliermondii and eradicate biofilms. It not only disrupted the respiratory chain and affected the metabolism and energy supply but also reduced the fungi adhesion and filament ...
