background and purpose: recently, release of pollutants such as pharmaceuticals to the environment becomes one of the most important problems for soil and water. the present study was conducted to introduce walnut shell-based activated carbon (ac) as a new low-cost adsorbent for the removal of cephalexin (cfx) antibiotic from aqueous solutions. materials and methods: this study was conducted in...

We previously demonstrated that brief nonkilling neutrophil exposure diminishes the binding affinity of S. aureus penicillin-binding protein (PBP) 2. We sought to investigate further the role of the neutrophil in the alteration of antimicrobial activity and its interaction with PBP-2 by studying the activity of cefotaxime, which highly binds to PBP 2, and cephalexin, which minimally binds to PB...

The introduction of pharmaceuticals into agricultural lands from the application biosolids and animal manure, irrigation with treated wastewater has led to concern for human health after ingestion pharmaceutical-tainted products. In this study, uptake accumulation cephalexin, a commonly prescribed antibiotic, was compared in three common vegetables (lettuce, celery, radish) grown nutrient solut...
