For the enhancement of the anticorrosion and antibacterial performance of the biomedical alloy Ti6Al4V, a novel Cu incorporated multilayer TaOceramic composite coating Cu-TaO/TaO/TaO-TiO/TiO/Ti (coating codeCu-MTaO) was developed by radio frequency (RF) and direct current (DC) reactive magnetron sputtering. Meanwhile, to better display the multilayer TaO coating mentioned above, a monolayer TaO ceramic coating was deposited onto the surface of Ti6Al4V alloy as a reference. The surface morphology, microstructure, phase constituents, and elemental states of the coating were evaluated by atomic force microscopy, scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, respectively.

Methods: In total, 96 preterm infants were randomly assigned to 3 groups: a control group receiving standard parenteral nutrition (group 1: n = 31), an iron-supplemented group (group 2: IS, n = 33), and an iron-supplemented combined erythropoietin group (group 3: IS+EPO, n = 32). The primary objective was to assess hemoglobin (Hb) levels.
