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), ...
N2O emissions from urine-treated tropical soil: Effects of soil moisture and compaction, urine composition, and dung addition
(2017-10-01)
Increasing attention is being paid to the importance of N2O emissions due to livestock activities in tropical countries. Understanding the key variables driving N2O emission could help minimize impacts of N2O release and ...
EXPOSICAO DE CIRURGIOES-DENTISTAS AO MERCURIO
(1981-12-01)
The professional exposure of dental surgeons to mercury has attracted a great deal of attention from governmental organs and institutions in different countries. Considering that the normal ratio is 10 μg/1000 ml of urine, ...
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 ...
Is urinary density an adequate predictor of urinary osmolality?
(BioMed Central, 2015)
Abstract
Background
Urinary density (UD) has been routinely used for decades as a surrogate marker for urine osmolality (Uosm). We asked if UD can accurately estimate Uosm ...
Determination of cinnamic acid in human urine by differential-pulse polarography
(Royal Soc Chemistry, 1996-02-01)
The differential pulse polarographic behaviour of cinnamic acid was studied in acetate and phosphate buffer solutions (pH 3.5-7.5). The reduction mechanism is discussed. The drug can be determined at pH 5.0 over the ...
Voltammetric sensor for amoxicillin determination in human urine using polyglutamic acid/glutaraldehyde film
(Elsevier B.V. Sa, 2008-08-12)
A voltammetric sensor for determination of amoxicillin (AMX) was developed based on a glutaraldehyde cross-linked polyglutamic acid modified glassy carbon electrode. The proposed method is based on pre-concentration of AMX ...
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 ...
Detection of Leptospira spp. in the semen and urine of bulls serologically reactive to Leptospira interrogans serovar hardjo
(Soc Brasileira Microbiologia, 2005-01-01)
This study evaluated PCR for the detection of leptospires in semen and urine of ten serologically reactive bulls, comparing these results with those obtained with other diagnosis techniques. Two collections of materials ...
Simple and rapid hplc-uv methods for gabapentin quantification in human plasma and urine: Applicability in pharmacokinetics and drug monitoring
(2021-01-01)
Aim: We aimed to develop methods to determine gabapentin (GAB) in biological samples using high-performance liquid chromatography (HPLC) with application in pharmacokinetics and therapeutic drug monitoring. Methods: Simple, ...
