Boron exposure assessment using drinking water and urine in the North of Chile
(2011)
Boron is an essential trace element for plants and humans however it is still an open question what levels of boron are actually safe for humans. This study, conducted between 2006 and 2010, measured exposure levels of ...
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 ...
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, ...
Paper platform for determination of bumetanide in human urine samples to detect doping in sports using digital image analysis
(2019-06-01)
Development and application of a new, simple, inexpensive, and eco-friendly method is presented for the quantification of bumetanide in human urine samples for the detection of doping in sports. The method involves the use ...
Effect of salt substitution on community-wide blood pressure and hypertension incidence
(Springer Nature, 2020)
Replacement of regular salt with potassium-enriched substitutes reduces blood pressure in controlled situations, mainly among people with hypertension. We report on a population-wide implementation of this strategy in a ...
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 ...
