The xerogel samples were prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method. In this investigation, a new molar ratio of H2O/TEOS was determined to be 11.7. Also, the necessary amounts of tri-hydrated copper nitrate and penta-hydrated copper sulfate were added to the solution in such a manner that the concentration of the copper oxide in final solut...
Copper plays a key role in the physiology of methanotrophs. One way that these bacteria meet their high copper requirement is by the biosynthesis and release of high affinity copper binding compounds called methanobactins. Recent advances in methanobactin characterization include the first crystal structure, detailed spectroscopic analyses, and studies of metal ion specificity. Methanobactin ma...
Background and purpose: In clinical treatment of cancer, improving the efficacy of drugs and targeted drug delivery have always been a fundamental problem requiring more focused solutions. The purpose of this study was to investigate the protective effects of copper nanoparticles in prostate normal and cancer cell lines. Materials and methods: In this experimental study, different concentrati...
Introduction: Herbal Compound and their essential oils possess high antimicrobial, antioxidant, and anti-tumor properties, but conventional prescribing of them faces serious challenges. Liposomal nano-carrier is one of the common pharmaceutical strategies to overcome these challenges. In this study, slow-released liposomal system containing Mentha piperita’s essential oil was prepared in ...
Slow waves determine frequency and propagation characteristics of contractions in the small intestine, yet little is known about mechanisms of slow wave regulation. We propose a role for intracellular Ca(2+), inositol 1,4,5,-trisphosphate (IP(3))-sensitive Ca(2+) release, and sarcoplasmic reticulum (SR) Ca(2+) content in the regulation of slow wave frequency because 1) 1,2-bis(2-aminophenoxy)et...
