Kinetics carried out in the presence of metal ions showed instead an increased reaction rate in the order Ca(2+) >> Mg(2+) > Na(+) >> K(+). Spectrofluorimetric measurements of PQQ with increasing concentrations of Ca(2+) showed a fluorescence quenching and shift of the maximum emission...
of solution, and it prevents the solution to be squeezed-out under an applied pressure29,30,31. The confined solution has a thickness of a few nanometers and consists of water layers that are strongly adsorbed to calcite and located underneath a layer of partially dehydrated calcium ions, and...
The method is based in an enzymatic reaction where the final product is measured at 500 nm (10). The detection limit was 1 mg/dL. The Ca+2 determinations were performed from seminal plasma (n = 52) by using an ALCYON® analyzer 300/300i with the B8D263 kit (Abbot, Madrid, Spain)...
Tricalcium silicate (TCS)-based materials produce calcium hydroxide as a byproduct of their hydration reaction. The present study investigated whether calcium ion release (CIR) affects their biological and antimicrobial properties when used as pulp protection materials. The effect of incorporation of micr...
Alkali–silica reaction (ASR) continues to be a major challenge to the durability of concrete structures. This is in part because the relationships between the composition, properties, and behavior of ASR gels in concrete are poorly understood. Gels with high pore solution pH, osmotic pressure, ...
-The production of ammonia in the Haber process. -The production of azo dyes from two aromatic rings bonding to a nitrogen atom, Ar-N. -The synthesis of slaked lime from calcium oxide and water. What is Synthesis in Chemistry? The word synthesis refers to the formation of new items throug...
Next, transcriptomic assays were combined with network pharmacology to identify the potential differentially expressed mRNAs. Immunofluorescence staining, real-time polymerase chain reaction, western blotting, and transmission electron microscopy were performed to elucidate the underlying mechanisms. Results BYHWD...
Calcination is a thermal processing technique used throughout a variety of industries to instigate a chemical reaction or physical change in a material. Most commonly, it refers to the chemical dissociation of components within a material, such as the separation of calcium carbonate to produce calciu...
As an internal standard, 270 ng of peptide derived from ovalbumin was spiked into each sample. After incubation at room temperature for 90 min with shaking, the reaction was quenched by adding 5% hydroxylamine to achieve a final concentration of 0.3% (v:v). TMT-labeled samples were pool...
12 In the SLE model, VBIT-4 prevented VDAC1 oligomerization and reduced mtDNA release, type-Ι interferon signaling, the neutrophil extracellular traps formation, and disease severity.12 Here, we demonstrate that VDAC1 is overexpressed in the colon of IBD patients and in mice with dextran ...
