The magnetic properties of the chain complex feature a ferrimagnetic behavior as well as slow magnetic relaxation typical for a single-chain magnet.展开更多

Methods: The apoptosis of purified cultured astrocytes and oligodendrocytes induced by Ca 2+ reperfusion and the relationship between the development of the cell apoptosis and post-reperfusion time was observed. Results: Both the astrocytes and oligodendrocytes were obviously in a time-dependent fashion, and the apoptosis ratios of the oligodendrocytes ( 39.73%± 4.16%) were higher than the astrocytes ( 19.64%± 4.67%) 24 hours after Ca 2+ reperfusion. The TUNEL positive cells were 13.6± 1.82 and 21.4± 1.95 at every visual field of astrocytes and oligodendrocytes respectively 24 hours after Ca 2+ reperfusion. Conclusions: The astrocytes and oligodendrocytes are similar with the development rules on apoptosis and have different susceptiveness to the situation.展开更多

In the present work, an "ensemble"-based colorimetric and fluorescent sensor(L2-Zn^(2+)) for CN^-ion has been developed. The addition of cyanide ions removed Zn^(2+) from the ensemble(L2-Zn^(2+)) in aqueous medium, resulting in a color change of the solution from red to buff and a "turn-on" fluorescent response. Also, the sensitivity of both the fluorescenceand colorimetric-based assay is below the maximum allowable level of cyanide ions in drinking water set by the World Health Organization. In addition, test strips, which served as convenient and efficient CN^- test kits, were fabricated based on the sensor.Notably, the selective detection of cyanide with L2-Zn^(2+) for practical application was also performed in sprouting potatoes.展开更多
