In this study biomimetic fluoridated phosphate doped hydrophilic coatings with various ions on CoCrMo alloy were pre- pared by electrodeposition. Cu and Zn ions were chosen for doping because of their well known antibacterial activity. The struc^xes of the coatings were identified using Fourier-transform Infrared （FTIR） analysis. X-ray Diffraction （XRD） analysis was performed to evaluate crystallite dimensions of the specimen surface. The contact angle was measured in order to establish the hydrophilic/hydrophobic balance and to compute surface energy. All studied samples have a hydrophilic character which is weaken after doping. The time evolution of ions releasing from the coatings was evaluated with an inductively plasma mass spectrometer after immersion in saline phosphate. The hemolytic experiments indicate that except the fluoridated coatings doped with Zn which is slightly hemolytic, all other samples are non hemolytic. The test for antibacterial activity for Staphy- lococcus aureus and Pseudomonas aeruginosa indicated that the fluoridated biomimetic coating doped with various positive ions increases bacterial growth inhibition level significantly. Fluoridated phosphate coating doped with Cu has best antibacterial activity

Crohn's disease(CD) represents a chronic transmural inflammatory condition of the gastrointestinal tract, which usually leads to structural damage and signific-ant disability. Deep remission--defined by both clinical and endoscopic remission, signifying mucosal healing-represents the current endpoint in the treat--to--target strategy, significantly improving patients' long--term outcomes. Transmural healing(TH) could be a more effe-ctive target, but this possibility remains unclear. This narrative review aims to critically review and summarize the available literature relating TH to long--term outcomes, being the first of its kind and to the best of the author's knowledge. A systematic literature search(from incep-tion to March 31 2018) was performed, using multiple databases, and identifying seven full--text manuscripts. In those studies, long--term favorable outcomes(≥ 52 wk) included sustained clinical remission, as well as fewer therapeutic changes, CD--related hospitalizations, and surgeries. Despite heterogeneous design and me-thodological limitations, six of the studies demonstrated that TH or intestinal healing(TH plus mucosal healing) were predictive for the aforementioned favorable out-comes. Therefore, TH may become a reasonable the-rapeutic target and be included in the concept of deep remission. Further prospective, well-designed, multicenter trials aiming to better define the role of TH in personalized therapy for CD and to determine the long-term influence of TH on bowel damage and disability are warranted.
