The effects of bivalent cations on cytochrome b5 reduction by NADH:cytochrome b5 reductase and NADPH:cytochrome c reductase were studied with the proteinase-solubilized enzymes. Cytochrome b5 reduction by NADH:cytochrome b5 reductase was strongly inhibited by CaCl2 or MgCl2. When 1.2 microM-cytochrome b5 was used, the concentrations of CaCl2 and MgCl2 required for 50% inhibition (I50) were 8 an...

Neuroprotective effect of vasopressin analogues, arginine Vasopressin (AVP) and lysine Vasopressin (LVP) was evaluated against MgCl2 induced cerebral ischemia model. AVP significantly prevented (P < 0.01) MgCl2 (1M) induced cerebral ischemia as compared to lysine Vasopressin (LVP) which was less effective (P < 0.05). Pretreatment with PI-3 kinase inhibitors, Wortmannin and LY-294002 (50 microg/...

Mg2+-induced polymerization of type III intermediate filament proteins vimentin and glial fibrillary acidic protein was studied by transient electric birefringence. In the absence of MgCl2 we found a net permanent dipole moment, approximately 45-nm-long dimers for vimentin, approximately 65-nm-long tetramers, hexamers, and possibly octamers for both proteins, and 100-nm aggregates for glial fib...

MgCl2/NaCl/KCl salt appeared as a high-potential heat transfer fluid for concentrated solar application, offering wide operating range and low cost. Nevertheless, MgCl2 hydrates atmosphere relative humidity are the limiting factors real scale CSP plant, leading to severe corrosion. Thus, Inconel 617 was tested at 700ºC up 24 h in air simulate punctual failure inertization system of plant. XRD S...

Cardiotoxin, protamine and polylysine are potent inhibitors of various cholinesterases. CaCl2 and MgCl2 overcome the inhibition. The order of addition of the inhibitor and the protecting agent (MgCl2) influences the final degree of the inhibition observed. These findings suggest that cardiotoxin, protamine and polylysine inhibit cholinesterases by the ionic binding of their basic groups with th...

Magnesium oxychloride cement (MOC) foam concrete (MOCFC) is an air-hardening cementing material formed by mixing magnesium chloride solution (MgCl2) and light-burned magnesia (i.e., active MgO). In application, adding caustic dolomite powder into magnesite can reduce the MOCFC production cost. The brine content of MOC changes with incorporation powder. This study investigated relationship betwe...

Summary Artificial N2 fixation is one of the most important industrial processes for human beings. However, current Haber-Bosch process based on fossil fuel suffers from unsustainability and a low to NH3 conversion. Here, we report magnesium chloride cycle synthesis H2O at atmospheric pressure. In this cycle, reacts with Mg form Mg3N2. Cl2 are produced by electrolysis molten MgCl2. NH4Cl used h...

Oxide ceramics could be attractive high-temperature construction materials for critical structural parts in molten salt thermal energy storage systems due to their excellent corrosion resistance and good mechanical properties. The 3D-printing technology allows the production of ceramic components with highly complex geometries, therefore extends applications. In this work, 3D-printed ZrO2 Al2O3...

Ni-catalyzed carboxylation of the C(sp(3))-Cl bond with CO2 in the presence of MgCl2 was theoretically investigated. MgCl2 plays three crucial roles in stabilization of a Ni(I)-CO2 adduct and acceleration of the CO2 insertion as a non-innocent additive and the one-electron reduction process as one kind of reagent.
