Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Supercritical Fluid Chromatography for Expedited Sample Clean‐Up in Isotope Ratio Mass Spectrometry Including Cholesterol as New Endogenous Reference Compound

Drug Testing and Analysis, EarlyView.
Supercritical fluid chromatography was employed in the sample preparation for IRMS determinations in sports drug testing for the first time and the developed method was successfully validated. Cholesterol (CHOL) was introduced as a novel endogenous reference compound and population‐based Δ‐values were established as shown here.

Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.

A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

Drug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

ESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).
