https://www.selleckchem.com/Androgen-Receptor.html There has been increasing interest in the use of a synthetic absorbable calcium sulfate (CaSO4 ) for local antibiotic delivery in orthopaedic infections. The purpose of this study was to quantify elution kinetics of six antibiotics (amikacin, meropenem, fosfomycin, minocycline, cefazolin, and dalbavancin) from a clinically relevant CaSO4 bead model and compare elution and antimicrobial activity to the current clinical gold standards vancomycin and tobramycin. Antibiotic-loaded synthetic CaSO4 beads were immersed in phosphate buffered saline and incubated at 37°C. Eluent was harvested at eight time points over 28 days. Antibiotic concentrations were measured by high performance liquid chromatography to quantify elution rates. CaSO4 beads demonstrated burst release kinetics. Dalbavancin, cefazolin, and minocycline all demonstrated similar elution profiles to vancomycin. Amikacin and meropenem demonstrated favorable elution profiles and durations of above-minimum inhibitory concentration when compared to tobramycin. Clinical Significance This study provides important novel data regarding the utility of amikacin, meropenem and dalbavancin as alternative choices to place in CaSO4 carriers when treating orthopaedic infections.Retraction "Advanced glycation end-products induce oxidative stress through the Sirt1/Nrf2 axis by interacting with the receptor of AGEs under diabetic conditions," by Xiao-Jun Chen, Wen-Jun Wu, Qi Zhou, Jin-Ping Jie, Xiong Chen, Fang Wang, and Xiao-Hua Gong, J Cell Biochem. 2019; 2159-2170 The above article, published online on 15 October 2018 in Wiley Online Library (https//onlinelibrary.wiley.com/doi/10.1002/jcb.27524) has been retracted by agreement between the authors, the journal's Editor in Chief, Prof. Dr. Christian Behl, and Wiley Periodicals LLC.
