A new bioactive compound, Mn3+-saturated bovine lactoferrin (Mn2-bLf) was obtained. It was stable under physiological conditions (pH ≈ 7.5) although gradually releases Mn2+ ions under the simulated intestinal conditions (pH ≈ 6.5). This feature m

NH3 temperature-programmed desorption (NH3 -TPD) is frequently used for probing the nature of the active sites in CuSSZ-13 zeolite for selective catalytic reduction (SCR) of NOx . Herein, we propose an interpretation of NH3 -TPD results, which takes

A series of eight copper (II) complexes with 3-(4-chloro-3-nitrophenyl)thiourea were designed and synthesized. The cytotoxic activity of all compounds was assessed in three human cancer cell lines (SW480, SW620, PC3) and human normal keratinocytes (H
