A new species of the ant genus Aenictus shuckard, A. henanensis, sp. nov., was collected from Yichuan County, Henan Province. The new species is close to A. lifuiae Terayama, but in profile view dorsum of propodeum straight, dorsum of petiolar node roundly convex, dorsum of propodeum entirely microreticulate. This new species is also close to A. ceylonicus (Mayr), but mandible with a large apical tooth, a small preapical tooth and followed by 5 indistinct minute denticles, subpetiolar process low and rounded, anterior half of pronotum microreticulate.

A liver-produced hormone, hepcidin, appears to be the key player in iron metabolism. The overexpression of hepcidin is the underlying cause of anemia of inflammation. The identification of compounds inhibiting hepcidin expression could ameliorate anemia associated with inflammation. In the current study, we have demonstrated for the first time that AG490 signifi cantly abolishes hepcidin expression in mice. Our work represents a novel approach to suppress hepcidin expression for treatment of anemia of inflammation and anemias occurring under other conditions.

A series of lanthanide complexes [Ln(4-Cl-2-MOBA)3phen]2(Ln=Sm(1), Nd(2), Ho(3), Eu(4), Dy(5), and Tb(6); 4-Cl-2-MOBA=4-chloro-2-methoxybenzoate, phen=1,10-phenanthroline) were synthesized and characterized. The single-crystal X-ray diffraction demonstrates that 1–3 are isomorphous, which present dimeric structures with four 4-Cl-2-MOBA anions function as bridging ligands. Complexes 1 and 4–6 display their characteristic luminescence emission bands of central Ln3?ions. The heat capacities, the thermodynamic functions and the thermogravimetry–Fourier transform infrared spectra of gaseous products of complexes 1–6 were *** non-isothermal kinetics of the second decomposition stage was studied by the integral isoconversional non-linear method and Stark method. Furthermore, 1–6 exhibited excellent antibacterial activity against Candida albicans,Escherichia coli and Staphylococcus aureu.

Three tetraurea-appended porphyrin derivatives were synthesized and applied as anion receptors to complex with various anions, including F^-, Cl^-, Br^-, I^-, NO3^-, HSO4^-, and AcO^-. The binding stoichiometries were all measured to be 1：1 and high binding abilities of these receptors toward the anions were demonstrated with the association constants of up to 1.1 × 10^8 L/mol. The complexation of the receptors with anions was further unambiguously confirmed by single-crystal X-ray analysis
