The synthesis of metallic nanoparticles is an active area of academic and, more significantly, applied research in nanotechnology. Several methods (chemical, physical or biological) have been introduced for the synthesis of these materials. In chemical reduction methods, for example, the reducing agent is a chemical solution, whereas in biological ones, the(More)
OBJECTIVES Surgical outcomes and bladder function were assessed in a group of patients who had undergone ureterocystoplasty while awaiting renal transplantation. METHODS An observational cohort study was performed. A chart review was performed of 16 patients who had undergone ureterocystoplasty between 1997 and 2006. The postoperative assessment included(More)
Saccharomyces cerevisiae PTCC5269 growth was evaluated to specify an optimum culture medium to reach the highest protein production. Experiment design was conducted using a fraction of the full factorial methodology, and signal to noise ratio was used for results analysis. Maximum cell of 8.84 log (CFU/mL) was resulted using optimized culture composed of(More)
The development of reliable processes for the synthesis of silver nanomaterials is an important aspect of current nanotechnology research. In this work, silver nanoparticles were produced in a bioreactor by Escherichia coli (E. coli). For this purpose, a process was designed and silver nanoparticles at a scale larger than laboratorial scale were produced by(More)
Today, the synthesis of silver nanoparticles (Ag NPs) is very common since it has many applications in different areas. The synthesis of these nanoparticles is done by means of physical, chemical, or biological methods. However, due to its inexpensive and environmentally friendly features, the biological method is more preferable. In the present study,(More)
