Quantitative paper chromatography of lipids [PDF]

Experientia, 1956
Ein qualitatives Verfahren zur papierchromatographischen Trennung von Fettsauren und Derivaten liess sich zur quantitativen Bestimmung ausbauen. Die Methode hat eine Fehlergrenze von etwa ± 5% und ist unabhangig von den funktionellen Gruppen der Molekule. Sie ist fur gesattigte Di- und Triglyceride nicht direkt anwendbar.

Plasma lipidomic and metabolomic profiles in high‐grade glioma patients before and after 72‐h presurgery water‐only fasting

Molecular Oncology, EarlyView.
Presurgery 72‐h fasting in GB patients leads to adaptations of plasma lipids and polar metabolites. Fasting reduces lysophosphatidylcholines and increases free fatty acids, shifts triglycerides toward long‐chain TGs and increases branched‐chain amino acids, alpha aminobutyric acid, and uric acid.

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

Molecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...
