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 ...
Toxicologic evaluation of acute and subacute oral administration of Cucurbita maxima seed extracts to rats and swine
(1994-07-04)
The extract prepared from dried seeds of Cucurbita maxima was administered to rats and pigs. Following a single dose or 4 weeks of daily oral administration, the extract produced no changes in serum glucose, urea, creatinine, ...

Simultaneous determination of renal function biomarkers in urine using a validated paper-based microfluidic analytical device
(2018-01-02)
In this paper, we describe a validated paper-based microfluidic analytical device for the simultaneous quantification of two important biomarkers of renal function in urine. This paper platform provides an inexpensive, ...
Nitrogen excretion during embryonic development of the green iguana, Iguana iguana (Reptilia; Squamata)
(2012-10-01)
Development within the cleidoic egg of birds and reptiles presents the embryo with the problem of accumulation of wastes from nitrogen metabolism. Ammonia derived from protein catabolism is converted into the less toxic ...

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 ...
Non-covalent functionalization of multi-wall carbon nanotubes with polyarginine: Characterization and analytical applications for uric acid quantification
(Wiley VCH Verlag, 2018-07)
We report for the first time the non-covalent functionalization of multiwall carbon nanotubes (MWCNTs) with polyarginine (Polyarg), the modification of glassy carbon electrodes (GCE) with the resulting Polyarg-MWCNTs ...
