Holmium oxide glass has been used as a wavelength standard for over four decades. These standards have shown insignificant spectral variation from batch to batch and from one manufacturer to another. The National Institute of Standards and Technology (NIST) has certified and recertified holmium oxide glass samples for over four decades. Over this period of time there has been no recorded instan...

introduction: in this research, [166ho]holmium chitosan complex production is described in details, followed by determination of complex radiochemical purity, stability and biodistribution (after intra-articular injection) in wild-type male rats. finally a ho-166 based chitosan kit for ultimate radiosynovectomy as well as radiotherapy applications was developed.methods: 166ho-chitosan complex w...

ABSTRACT Background: Holmium YAG (yttrium-aluminum-garnet) laser, a comparatively new technique, can clear all types and sizes of stones is only being used in two institutes Karachi, Pakistan. The study aimed to compare pneumatic lithoclast holmium evaluate stone-free rate (SFR), postoperative complications, operative duration, effectiveness. Methods: This cross-sectional research included 60 p...

Introduction: The aim of this study is to compare holmium laser (LL) with pneumatic lithoclast (PL) in patients with upper ureteral stones and their ability to destruct the stones and making the patient stone free. We also compare the duration of these procedures and their complications, such as urosepsis, perforation, and pushing the stone backward. Methods: This has been a clinical randomized...
