“…Jaiyeoba (2003) noted that cation exchange capacity (CEC) declines after crop cultivation [22]. Cultivation and its management, i.e., fertilization and irrigation, governs SIC dynamics in soils through regulating the soil environment, SOC contents, and hydrological conditions [23,24]. Dong et al (2017) noted that long-term fertilizer significantly decreased SIC content in a two-year crop rotation system, that is, winter wheat, summer corn, spring corn, and winter fallow for each two-year period [25], while Bughio et al (2016) reported that irrigation and fertilization in a wheat-maize rotation system increased SIC content when compared with bare field [17].…”

Soil organic carbon (SOC) and soil inorganic carbon (SIC) play essential roles in carbon cycling in terrestrial ecosystems; however, the effects of crop cultivation on them are still poorly understood, especially in alkali sodic soils widely distributed in semiarid regions. Alkali sodic soils from cornfields and paddies with cultivation years of 5, 15, and 25 were analyzed here to assess the response of soil properties and soil carbon pools to crop cultivation. Soil pH and exchangeable sodium percentages decrease in accordance with cultivation years, while enzyme activity (amylase, invertase, and catalase) shows a contrary trend. Soil pH and exchangeable sodium percentages are negatively correlated with SOC, but positively correlated with SIC. Redundancy analysis reveals an obvious relationship between SOC and invertase activity. The percentage of δ 13 C SOC found here is approximately -24.78% to -22.97% for cornfields and approximately -26.54% to -23.81% for paddies, suggesting that crop cultivation contributes to SOC sequestration and stocking, increasing with cultivation years. The percentage of δ 13 C SIC found here is approximately 1.90% to 3.73% , proving that lithogenic inorganic carbon is the major SIC, where the stock decreases with increasing cultivation years. Significant total carbon stock loss is observed in cornfields, while it is preserved at 120 Mg ha −1 in paddies. We conclude here from the results that corn and rice cultivation reduce alkali sodic conditions in soil, thereby improving soil enzymes and favoring SOC stocking, but reducing SIC stocks.

“…In blood serum, the Mg/Ca ratio of about 0.3 is naturally sufficient to prevent HA precipitation in the body fluids. A similar role is performed by Mg ions in sea water, by controlling calcite (CaCO 3 ) growth rate [ 25 ]. Aluminium (Al) ions can also delay HA formation by adsorbing onto the surface of growing HA crystals.…”

Pathologic calcification leads to structural deterioration of implant materials via stiffening, stress cracking, and other structural disintegration mechanisms, and the effect can be critical for implants intended for long-term or permanent implantation. This study demonstrates the potential of using specific metal ions (MI)s for inhibiting pathological calcification in polyurethane (PU) implants. The hypothesis of using MIs as anti-calcification agents was based on the natural calcium-antagonist role of Mg2+ ions in human body, and the anti-calcification effect of Fe3+ ions in bio-prosthetic heart valves has previously been confirmed. In vitro calcification results indicated that a protective covering mesh of MI-doped PU can prevent calcification by preventing hydroxyapatite crystal growth. However, microstructure and mechanical characterisation revealed oxidative degradation effects from Fe3+ ions on the mechanical properties of the PU matrix. Therefore, from both a mechanical and anti-calcification effects point of view, Mg2+ ions are more promising candidates than Fe3+ ions. The in vitro MI release experiments demonstrated that PU microphase separation and the structural design of PU-MI matrices were important determinants of release kinetics. Increased phase separation in doped PU assisted in consistent long-term release of dissolved MIs from both hard and soft segments of the PU. The use of a composite-sandwich mesh design prevented an initial burst release which improved the late (>20 days) release rate of MIs from the matrix.
