Copper(II) chloride anionic coordination complexes with different imidazole-derived ligands due to the potential cytotoxic activity play the important role in protein. By investigating the experimental electron paramagnetic resonance (EPR) and ultraviolet-visible (UV-vis) spectra of [CuCl(CHN)]Cl, [CuCl(CHN)]Cl, [CuCl(CHN)], and [CuCl(CHN)]Cl·2HO, the local structure of the corresponding Cu centers and the role of different ligands are obtained. Based on the well-agreed EPR parameters and the d-d transitions (10D), the four Cu centers show tetragonal and orthorhombic distortion, corresponding to the different anisotropies of EPR signals.

Intestinal ischemia/reperfusion (I/R), which is associated with high morbidity and mortality, is also accompanied with abnormal energy metabolism and liver injury. Irisin, a novel exercise-induced hormone, can regulate adipose browning and thermogenesis. The following study investigated the potential role of dexmedetomidine in liver injury during intestinal I/R in rats.

The results showed that the soil organic carbon mineralization of all the three treatments was almost the same. The daily SOC mineralization rate first increased and then decreased, and finally tended to be stable.
