background: excess serum uric acid (ua) accumulation can lead to various diseases. increasing evidences reveal that ua may have a key role in the pathogenesis of metabolic syndrome. little is known about the associations of ua levels with cardiometabolic risk factors in prediabetic individuals. this study was designed to evaluate the association between ua and cardiometabolic risk factors in pr...

developing simple, sensitive and selective sensing systems for dopamine is important due to its biological significance. in this work, a silver nanoparticles-modified carbon paste electrode (agnps-cpe) has been constructed and used to detect of dopamine (da) in the simultaneous presence of ascorbic acid (aa) and uric acid (ua) at neutral ph 7.0 by cyclic voltammetry. the modified electrode show...

fabrication and electrochemical characterization of a sensor for the determination of epinephrine (ep), uric acid (ua) and folic acid (fa) is described. the sensor  was prepared using carbon paste electrode (cpe) modified with 3,4-dihydroxybenzaldehyde-2,4-dinitrophenylhydrazone (ddp) and carbon nanotubes (cnts), which makes the modified electrode highly sensitive for the electrochemical detect...

ABSTRACT: 
 Aim:
 To determine the density and chemical structure of renal stones by using in vivo low dose helical computerized tomography.
 Methods:
 79 patients with or uretheral were included our study who going to have extracorporeal shock wave lithotripsy (ESWL) planned go through urinary stone surgery due stones. All densities measured Hounsfield Unit abdominal non-co...

OBJECTIVE Our aim was to determine, using CT attenuation values, the chemical composition of 241 human renal stones placed in a jelly phantom and to analyze the influence of respiratory motion on the classification. MATERIALS AND METHODS The stones were placed in a jelly simulating the X-ray attenuation of the kidneys. A dynamic platform was used to apply to the phantom free-breathing motion ...

BACKGROUND Observational studies in obese adults have found abnormal urinary metabolic indices that predispose to nephrolithiasis. Few studies have been performed in severely obese adolescents. OBJECTIVES To assess urinary stone risk factors in severely obese adolescents and in those undergoing 2 types of weight loss surgery. SETTING Children's hospital, United States. METHODS A prospecti...
