Preservation of urine samples for metabolic evaluation of stone-forming patients
(Springer, 2006-10-01)
Metabolic evaluation of stone-forming (SF) patients is based on the determination of calcium, oxalate, citrate, uric acid and other parameters in 24-h urine samples under a random diet. A reliable measurement of urinary ...
Role of self-sampling for the diagnosis of human papillomavirus in rural areas from Cuenca Ecuador: Acceptance, sensitivity and specificity among urine sampling, self-sampling and clinician sampling
(EUROGIN 2023, 2023)
Background/Objectives: Background: During 2020, 1534 new cases of cervical cancer were reported in Ecuador and 813 women
died from this cause. Pap smear has decreased mortality of (CC), however in Ecuador 41.6% of women ...
Differential pulse polarographic determination of ceftazidime in urine samples with and without prior extraction
(Elsevier B.V., 1997-09-30)
Ceftazidime shows two main polarographic reduction peaks at pH 4.0, that at -0.45 V owing to reduction of the C=N bond in the methylethoxyimino group and that at -1.00 V owing to the reductive elimination of pyridine: the ...
Fast ultrasound-assisted treatment of urine samples for chronopotentiometric stripping determination of mercury at gold film electrodes
(Elsevier B.V., 2006-06-30)
This work describes an efficient, fast, and reliable analytical methodology for mercury determination in urine samples using stripping chronopotentiometry at gold film electrodes. The samples were sonicated in the presence ...

Urine dilution boosts the electricity production in bio-electrochemical systems powered by un-pretreated human urine
(Elsevier Science SA, 2021-02)
Human urine can be turned into electricity in bio-electrochemical systems. The acclimation of electro-active bacteria to culture media with increasing urine concentrations has led to raising the obtained current densities, ...
A flow-based procedure with solenoid micro-pumps for the spectrophotometric determination of uric acid in urine
(ELSEVIER SCIENCE BV, 2010)
The determination of uric acid in urine shows clinical importance, once it can be related to human organism dysfunctions, such as gout. An analytical procedure employing a multicommuted flow system was developed for the ...
