Gamma irradiation was tested as a method for sterilization of pluronic F-127 gel to be used for ocular delivery of ciprofloxacin (CFX). The effect of gamma irradiation on the properties of pluronic gels was studied at different irradiation doses and pluronic copolymer concentrations. The flow of pluronic gels of different concentrations was non-Newtonian with thixotropic pseudoplastic propertie...

Ceftriaxone (cfx), a third-generation cephalosporin antibiotic, leads to transient cholelithiasis in some children, also known as pseudolithiasis. However, the underlying pathogenetic mechanism of this adverse effect has not yet been elucidated. We describe 3 children with ceftriaxone-induced pseudolithiasis, who were also carriers of the A(TA)(7)TAA polymorphism of the UGT1A1 gene, implying th...

Cefoxitin (CFX), cefmetazole (CMZ) and YM093301), and 6059-S2) have a 7a-methoxyl group (a unique structural feature of the cephamycin family) in the cephalosporin nucleus and 1oxa cephalosporin nucleus, respectively (Fig. 1). These compounds are resistant to hydrolysis by various bacterial i3-lactamases. This resistance character also provides the antibiotic with a broad antibacterial spectrum...

Environmental pollution due to antibiotics is a serious problem. In this work, the adsorption and desorption of antibiotic cefuroxime (CFX) were studied in four by-products/residues from forestry food industries. For this, batch-type experiments carried out, adding increasing concentrations CFX (from 0 50 µmol L?1) 0.5 g adsorbent. The materials with pH higher than 9 (mussel shell wood ash) tho...
