Sustainable analytical approaches for microplastics in wastewater, sludge, and landfills: Challenges, fate, and green chemistry perspectives

Advances in Sample Preparation
The effects of microplastics (MPs) in wastewater, sludge, and landfills are analyzed and discussed, focusing on their pathways into the environment. The application of sludge as a soil amendment and the reuse of treated wastewater in agriculture have ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Revaluing optical techniques in the light of vortex- and ultrasound-assisted microextraction

Advances in Sample Preparation
The main objective of this review is to provide an overview of the coupling between microextraction techniques (mainly based on the use of vortex and ultrasound) and different optical techniques in order to demonstrate that their combination can be a ...

Sampling and Sample Preparation

, 2010
Food quality is monitored at various processing stages, but 100% inspection is rarely possible, or even desirable. To ensure a representative sample of the population is obtained for analysis, sampling and sample reduction methods must be developed and implemented.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Natural deep eutectic solvent-based matrix solid-phase dispersion-ultrasound assisted extraction of pesticides in pears and their determination by liquid chromatography-tandem mass spectrometry

Advances in Sample Preparation
In recent years, natural deep eutectic solvents (NADES) have been proposed as sustainable solvents capable of replacing the conventional harmful organic solvents typically used in sample preparation.

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Identification of the plant mitochondrial OrfX protein: A mass spectrometry approach

FEBS Letters, EarlyView.
The mitochondrial genome of plants contains an open reading frame, orfx, which encodes a rare protein that has so far escaped mass spectrometric detection. The protein resembles the c‐subunit of bacterial twin‐arginine‐motif‐dependent protein translocases (TatC).

Multiple-shell amorphous Co/Ni-(PO4)x(OH)y hollow layered double hydroxide for enhanced extraction of some azole antifungals from biological samples

Advances in Sample Preparation
Antifungals drugs are widely used for variety of fungal infections. Extraction and determination of these drugs in biological sample is crucial because of their toxicity, endocrine-disrupting, and cytochrome P450-mediated effects. In addition, developing
