Influence of 2% chlorhexidine on pH, calcium release and setting time of a resinous MTA-based root-end filling material

Brazilian Oral Research, 2015
The addition of chlorhexidine (CHX) to a resinous experimental Mineral Trioxide Aggregate (E-MTA) based root-end filling material is an alternative to boost its antimicrobial activity.

Formation of vacancy-type defects and hydride introduced by irradiation in pure titanium

Journal of Materials Research and Technology, 2023
The effect of hydrogen ion irradiation on the formation of hydride and vacancy-type defects in pure titanium was investigated by X-ray diffraction (XRD), Doppler broadening spectrum (DBS), and coincidence Doppler broadening spectrum (CDB) based on slow ...

Comparison of ion cyclotron wall conditioning discharges in hydrogen and helium in JET

Nuclear Materials and Energy, 2023
This paper explores the plasma parameters of helium and hydrogen Ion Cyclotron Wall Conditioning (ICWC) discharges performed in JET as part of a He/H fuelling changeover experiment. The conducted study shows that plasma with a higher density is formed in

Investigating pH and other electrical properties of potassium salt solutions

Food Chemistry Advances, 2023
A recent study of ours reported that pH of common salts varies with concentration at room temperature. It can either increase in case of basic salts or decrease in case of acidic salts.

Determination of Lactate by Sequential Injection Analysis Using a Fluoride Ion-selective Electrode Detector

Electrochemistry, 2020
A combination of sequential Injection Analysis (SIA) system and the ion-selective electrode (ISE) detector is considered to be one of a very effective analytical method. Reaction of lactate with lactate oxidase produces pyruvic acid and hydrogen peroxide.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
