Risk factors for early severe preeclampsia in obstetric antiphospholipid syndrome with conventional treatment. The impact of hydroxychloroquine
(Sage Publications Ltd, 2020-08)
Objective: The first aim was to retrospectively identify risk factors for the development of early severe preeclampsia (sPE) in patients with obstetric antiphospholipid syndrome (OAPS) who received conventional treatment ...
Development of monolithic sorbent cartridges (m-SPE) for the extraction of non-steroidal anti-inflammatory drugs from surface waters and their determination by HPLC
(Elsevier Science, 2020-12)
A novel and simple analytical methodology including solid-phase extraction using a monolithic sorbent (m-SPE), coupled to reverse phase liquid chromatography analysis, to determine seven non-steroidal anti-inflammatory ...

Activated carbon from peanut shells: 2,4-D desorption kinetics study for application as a green material for analytical purposes
(Elsevier, 2020-10-19)
The desorption kinetic of 2,4 Dichlorophenoxyacetic acid (2,4-D) herbicide initially adsorbed on activated carbon from peanut shells (PSAC) was studied. The herbicide was adsorbed at pH 3.0 and desorbed in aqueous solutions ...
Analysis of phenolic compounds in onion nectar by miniaturized off-line solid phase extraction-capillary zone electrophoresis
(Royal Society of Chemistry, 2014-07-16)
Onion is an important vegetable crop which depends heavily on cross-pollinating insects for any significant increase in seed production. Nectar is the most important floral reward offered by plants. Minor components such ...
Application of a nickel hydroxide gold nanoparticles screen-printed electrode for impedimetric sensing of glucose in artificial saliva
(Elsevier Science SA, 2019-01)
In this study, a non-enzymatic glucose sensor (NEGs) based on the electrochemical deposition of nickel nanoparticles on screen-printed electrodes modified with gold nanoparticles, Ni(OH) 2 /AuNp/SPE, is obtained. SEM and ...
