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 ...
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 ...
Enzymatic-spectrophotometric determination of paraquat in urine samples: A method based on its toxic mechanism
(TAYLOR & FRANCIS INC, 2010)
Paraquat is a broad-spectrum contact herbicide that has been encountered worldwide in several cases of accidental, homicidal, and suicidal poisonings. The pulmonary toxicity of this compound is related to the depletion of ...
Electrophoretic pattern of concentrated urine: Comparison between 24-hour collection and random samples:
(W B Saunders CoPhiladelphiaEUA, 2002)
First-void versus midstream urine culture for detection of Ureaplasma urealyticum in the urinary tract
(Soc Brasileira Microbiologia, 1995-07-01)
Quantitative Ureaplasma urealyticum culture was performed on clean first-void and midstream urine to evaluate the presence of these mollicutes in the urinary tract. The results, expressed as color changing units (CCU), ...
Human papillomavirus detection from human immunodeficiency virus-infected colombian women's paired urine and cervical samples
(Universidad del Rosario, 2013)
Infection, coinfection and type-specific human papillomavirus (HPV) distribution was evaluated in human immunodeficiency virus (HIV)-positive women from paired cervical and urine samples. Paired cervical and urine samples ...
Simultaneous determination of Cr, Ni and V in urine by ET AAS
(Sociedade Brasileira de Química, http://quimicanova.sbq.org.br/index.php, 2013)
Design and use of mouse control DNA for DNA biomarker extraction and PCR detection from urine: Application for transrenal Mycobacterium tuberculosis DNA detection
Urine samples are increasingly used for diagnosing infections including Escherichia coli, Ebola virus, and Zika virus. However, extraction and concentration of nucleic acid biomarkers from urine is necessary for many ...
A glassy carbon electrode modified with reduced graphene oxide for sensitive determination of bumetanide in urine at levels required for doping analysis
The dopant bumetanide (BMT) was banned by the World Anti-Doping Agency. The authors describe a voltammetric sensor for the determination of BMT in urine that is based on the use of a glassy carbon electrode modified with ...
