Sperm retrieval success and testicular histopathology in idiopathic nonobstructive azoospermia

open access: yesAsian Journal of Andrology, 2020
Prior studies have investigated sperm retrieval rates in men with nonobstructive azoospermia (NOA) secondary to specific etiologies, yet most cases of NOA are idiopathic.

Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots

open access: yesAdvanced Healthcare Materials, EarlyView.
Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...
