Bacterial leakage assessment in root canals sealed with AH Plus sealer modified with silver nanoparticles

BMC Oral Health, 2021
Background Successful endodontic therapy requires prevention of bacterial leakage between the root canal filing and root-canal walls. Sealing quality of a root canal filling depends strongly on the sealing ability of the sealer used.

Analysis the influence of corrosion layer on the grounding performance of grounding electrodes

IET Generation, Transmission & Distribution, 2020
The grounding electrode buried in soil is prone to corrosion affected by soil and leakage current. The surface of corroded grounding electrodes is wrapped with corrosion product, which affects the normal current dissipation process and weakens the ...

Surface Leakage Resistance of Glasses

Journal of the Ceramic Association, Japan, 1962
Glass rods for lamp and tube of about 4mm in diameter were provided with two electrodes at the distance of 30-40mm, and the apparent resistance, which is equivalent to the combination of volume and surface resistance connected pararell, were measured by the method of filament electrometer or direct deflection.In the first series of the experiment the ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Improved Objective Functions to Search for 8 × 8 Bijective S-Boxes With Theoretical Resistance Against Power Attacks Under Hamming Leakage Models

IEEE Access, 2022
Many research focuses on finding S-boxes with good cryptographic properties applying a heuristic method and a balanced, objective function. The design of S-boxes with theoretical resistance against Side-Channel Attacks by power consumption is addressed ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
