PURPOSE To assess the potential of dual-energy computed tomography (DECT) to identify urinary stone components, particularly uric acid and calcium oxalate monohydrate, which are unsuitable for extracorporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS This clinical study included 246 patients who underwent removal of urinary stones and an analysis of stone components between November...

Creatine exerts beneficial effects on a variety of pathologies in which energy metabolism and oxidative stress play an etiological role. Creatine supplements have shown beneficial effects on neurological disorders including Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Alzheimer's disease and stroke. However, the potential benefits of creatine for patients with convu...

The aim of this study is to investigate the hydration and the dehydration processes of calcium benzoate hydrates (trihydrate and monohydrate), thermotropic mesophases (dehydrated mesophase and lyophilized mesophase) and amorphous state, and the influence of their molecular order on those processes. X-ray analysis revealed that trihydrate has a planar structure composed of two types of planes-on...

A simple and rapid reversed-phase HPLC/UV procedure for the examination of creatine and creatinine on a Thermo Scientific Hypercarb (porous graphitic carbon) column is described herein. Under reversed-phase, isocratic conditions, excellent separation of these polar analytes is achieved within five minutes and the chromatographic data exhibit excellent precision. Introduction Creatine [2-(methyl...
