Phosphotungstate-sandwiched between cerium oxide and gold nanoparticles exhibit enhanced catalytic reduction of 4-nitrophenol and peroxidase enzyme-like activity.

The catalytic performance of gold (Au) decorated cerium oxide nanoparticles (nanoceria) can be potentially crucial because such a defined arrangement of multiple materials may provide improved chemical and biological catalytic activities. In this work, we have utilized a highly localized approach to reduce Au nanoparticles (AuNPs) on the nanoceria-phosphotungstate composite's surface. Phosphotungstic acid (PTA) bound on nanoceria's surface acts as a UV-light dependent redox molecule that specifically reduces AuNPs.

Bladder Endometriosis: Management by Cystoscopic and Laparoscopic Approaches.

Study Objective: Endometriosis of the urinary system accounts for less than 1% of all endometriosis, wherein bladder endometriosis is the most common. Bladder endometriosis is defined as endometriosis infiltrating the detrusor muscle and represents 85% of urinary tract endometriosis [1,2]. Segmental bladder resection/partial cystectomy is the bladder-preserving surgery and offers the complete removal of bladder endometriotic nodules [3,4].
