Apatite seeding and bone mineralization studies were carried out with Simulated body fluid and characterized structurally and morphologically.Curcumin is a plant-derived polyphenolic active substance with broad-spectrum antibacterial properties. Curcumin blocks bacterial growth owing to its structural characteristics and the generation of anti-oxidation products. Curcumin can inhibit bacterial virulence factors, inhibit bacterial biofilm formation and prevent bacterial adhesion to host receptors through the bacterial quorum sensing regulation system. As a photosensitizer, curcumin acts under blue light irradiation to induce phototoxicity and inhibit bacterial growth. Moreover, it can exert a synergistic antibacterial effect with other antibacterial substances. In this review, we summarize the research progress on the antibacterial mechanism of curcumin based on five targeting structures and two modes of action. Our discussion provides a theoretical basis and technical foundation for the development and application of natural antibacterial agents.Two cases of middle-aged female patients treated by gastric bypass surgery for weight loss presented to our clinic for a follow-up examination 3-6 months after the surgical procedure (a mini gastric bypass and a modified single anastomosis sleeve-ileostomy). In both patients increased ACTH levels and either high serum cortisol or an increased urinary cortisol excretion was apparent and triggered further endocrine testing. Serum cortisol could not be suppressed adequately by 2 and 4 mg dexamethasone in the standardized oral overnight suppression test while midnight salivary cortisol dropped well below the desired cut-off. This led to the hypothesis of an impaired dexamethasone r
