A miniaturized QuEChERS-DLLME method for simultaneous determination of acetamide, acrylamide, and glycidamide in infant formula using GC–MS

Advances in Sample Preparation
Infant formula is the only food product suitable for infants during the first months of life. Therefore, evaluating food contaminants is essential for ensuring infant food safety.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

One step derivatization and switchable hydrophilicity solvent-based microextraction for the determination of adamantane analogues in human urine by HPLC-FLD

Advances in Sample Preparation
The present study describes an “one-step” derivatization and microextraction using a pH-switchable hydrophilicity solvent for the determination of amantadine and memantine in human urine by liquid chromatography and fluorescence detection.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Determination of acylcarnitines in intact brain tumors using coated blade spray mass spectrometry (CBS-MS)

Advances in Sample Preparation
Potential biomarkers of cancerous alterations could be selected by profiling a wide range of analytes. For this purpose, analytical platforms enabling detailed analysis of different biological matrices are applied.

Local deformations and incommensurability of high quality epitaxial graphene on a weakly interacting transition metal [PDF]

, 2012
We investigate the fine structure of graphene on iridium, which is a model for graphene weakly interacting with a transition metal substrate. Even the highest quality epitaxial graphene displays tiny imperfections, i.e. small biaxial strains, ca.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The properties of the gamma-ray blazars in the CJ-F VLBI sample [PDF]

, 2001
We present first results from the analysis of multi-epoch VLBI observations of the EGRET detected sources [9] in the CJ-F sample (Caltech Jodrell-Flat-spectrum, [10]).
