Transitional Metaplasia of Renal Collecting Ducts in Vesicoureteral Reflux and Chronic Pyelonephritis: An Immunohistochemical Study of a Case and Review of the Literature.

The capability of the urinary tract to undergo metaplastic changes such as squamous, intestinal, glandular, mucinous, or ciliated epithelium in renal pelvis has been previously reported, which hypothetically is due to the mechanical irritation of the transitional epithelium. However, transitional metaplasia is a rare presentation in the collecting ducts. The aim of this paper was to report this type of extremely rare metaplasia and to inform pathologists that they may encounter this kind of metaplasia.

Administration of Silver Nanoparticles in Diabetes Mellitus: A Systematic Review and Meta-analysis on Animal Studies.

Biological features of silver nanoparticles in rising the insulin level of diabetic animal models were considered in recent years, which resulted in decreasing hyperglycemia condition. We reviewed the published literature to investigate the possible role of silver nanoparticles (Ag-NPs) throughout the treatment of diabetes mellitus in animal studies. In this systematic review and meta-analysis, we performed a search throughout the English literature of electronic databases, including Scopus, PubMed, and ISI Web of Science, up to the date of May 22, 2020.
