Periodontal infection is a long-lasting inflammatory condition caused by the growth and development of an abnormal and harmful community of microorganisms. This destructive illness leads to the loss of the tissues that support the teeth, degradation of t
The images of bacteria MKMB01 and MKMB02 that had adhered to the HT-29 cells and biofilm production were taken with a Sigma Field Emission Scanning Electron Microscope (FESEM) (Zeiss SIGMA VP-FESEM, Zeiss, Germany). Transepithelial Electrical Resistance (TEER) assay The TEER assay is a ...
2B). Notably, these EPS and biofilm could act like a “mineral glue” [16] which therefore adhere and bind the mineral particles to form the organo-mineral aggregates in BAC of aquatic systems. Moreover, the inner microstructure visualized by stereomicroscopy and SEM showed that filamentous ...
tetragonal hausmannite structure. The manganese oxide nanostructures were characterized using TEM, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). Wu et al. Their study reported a one-step synthetic protocol for reducing manganese from KMnO₄ t...
FESEM micrograph of the N-doped carbon hollow microspheres show that the spherical morphology is well retained with a uniform size of ~ 120 nm, implying that the hollow structure should have great mechanical strength (Fig. 1e). TEM images of the N-doped carbon hollow microspheres (Fig. 1f)...
3.6Field emission scanning electron microscopy (FESEM) analysis The mechanical characteristics of CR concrete were improved with addition of PVA fiber in this research work. To get a deeper understanding of this enhancement procedure, rubberized concrete specimens with different concentrations of PVA fiber...
After critical point drying, they were observed with a SEM S-4800 FESEM (Hitachi, Japan). RNA isolation and microarray hybridization Total RNA was extracted using prechilled Trizol reagent (Invitrogen, Carlsbad, CA) according to the manufacturer’s directions with some modifications. The RNA was ...
The M1 biofilm, although the thinnest, seems to consist of densely-packed cells that form continuous layers, while the M28 and especially M41 biofilms seem to be less dense but exhibit more elevated supracellular assembly. We therefore used field emission scanning electron microscopy (FESEM) to ...
In addition, the Fe 2p3/2peak of Fe-CDs was accompanied by an adjacent characteristic satellite peak, which was ascribed as the oxidized ionic form of Fe [48]. This was possibly due to the oxidation of Fe ions in the raw precursor caused by the high temperature and oxygen ambience from...
A 10 kV FESEM (S-4800, HITACHI, Tokyo, Japan) equipped with energy dispersive spectroscopy (EDS) capabilities was used to scan the chemical morphology map and various elemental contents of the cross sections of each scaffold. In vitro cell experiments Cell culture Sprague–Dawley (SD) rats (...
