Comparison of inducible nitric oxide synthase activity in pancreatic islets of young and aged rats

Objective(s):Some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. Incidence of these condition increases with aging. On the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (NOS) activity is also altered in diabetes.

High-Grade Urothelial Carcinoma of Bladder Transforming to Micropapillary Variant on Follow-Up

Micropapillary variant of urothelial carcinoma (UC) of the bladder is an aggressive tumour, comprising 0.6-6% of all UC.
