Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Quantification of Sulfonated Polyacrylamides by SEC‐UV in Produced Water: Validation and Oilfield Case Study

Journal of Applied Polymer Science, EarlyView.
Size exclusion chromatography with UV–vis detection, combined with ultrasonication pretreatment, enables sensitive detection and quantification of back‐produced polymer at very low concentrations in produced water. This approach supports reliable polymer monitoring and offers a practical route to improve surveillance of polymer flooding performance ...

Population pharmacokinetics of levofloxacin in breastmilk in patients with rifampicin‐resistant tuberculosis

British Journal of Clinical Pharmacology, EarlyView.
Levofloxacin is a widely used antibiotic included in rifampicin‐resistant tuberculosis (RR‐TB) treatment. Data describing levofloxacin concentrations in breastmilk and infant exposure are limited. We analysed data from two South African studies of breastfeeding women receiving levofloxacin (750–1000 mg daily) for RR‐TB.

Development and validation of spectrofluorimetric and LC–MS/MS methods for the determination of hesperidin in human plasma and pharmaceutical forms [PDF]

Journal of the Serbian Chemical Society, 2012
The spectrofluorometric method, based on fluorescence properties of aluminium (III)–hesperidin complex, for the determination of hesperidin in human plasma and pharmaceutical forms has been developed and validated. The complex shows strong emission in

A dose‐finding population pharmacokinetic/pharmacodynamic model of ginisortamab, an anti‐gremlin‐1 monoclonal antibody, in patients with solid tumours

British Journal of Clinical Pharmacology, EarlyView.
Aims Ginisortamab, a first‐in‐class human monoclonal antibody for the treatment of advanced solid tumours, binds to gremlin‐1 and restores bone morphogenetic protein signalling. We used pharmacokinetic/pharmacodynamic (PK/PD) modelling to characterize the relationship between ginisortamab dose and serum gremlin‐1 binding, using model‐based simulations ...

Comparison of the extractability of organophosphorus flame retardants in landfill media using organic and green solvents

Scientific Reports, 2022
Organic solvents are mainly used in the extraction of organophosphorus flame retardants (OPFRs) because of their availability and having been tested as good extracting solvents for most environmental pollutants.

Pregnancy‐related effect on elexacaftor, tezacaftor and ivacaftor pharmacokinetics in women with cystic fibrosis

British Journal of Clinical Pharmacology, EarlyView.
Aim The number of pregnancies among women with cystic fibrosis (wwCF) has steadily increased over the past decade. However, the pharmacokinetics (PK) of elexacaftor–tezacaftor–ivacaftor (ETI) during gestation remains uncharacterized, despite its widespread use in this population.
