The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Self‐Calibrating Ratiometric DNA Aptamer Probe for Quantitative ATP Imaging in Living Cells

open access: yesChemistry – A European Journal, EarlyView.
We developed the RFA–ECHO probe, an internally calibrated ATP sensor that remains responsive across millimolar ATP levels. Its self‐correcting Cy5/ECHO ratio ensures accurate quantification independent of probe uptake. Compared with FRET‐based sensors, it yields a robust ratiometric shift, distinguishing high‐ATP cancer cells from normal ones, enabling

Improvement of EPO Transgene Detection From Polymeric Dried Blood Spots for Antidoping Application

open access: yesDrug Testing and Analysis, EarlyView.
This article presents an optimized protocol for gene doping detection. Starting from one spot DBS (20 μL), concentrated DNA was obtained and real‐time PCR parameters were adjusted for increased detection. Robust detection of 5000 copies/mL of transgene was validated for polymeric device TASSO M‐20.

Further Insights Into the Metabolism of LGD‐4033 in Human Urine. Part 1. Structure Elucidation of Additional Important Metabolites

open access: yesDrug Testing and Analysis, EarlyView.
Well‐characterized, chemically synthesized molecules related to LGD‐4033 metabolism were used as analytical standards for the analysis of LGD‐4033 post‐administration urine samples. This approach offered further insights into LGD‐4033 metabolism, providing solid experimental proof for the structure of important previously reported metabolites and ...

Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)

open access: yesDrug Testing and Analysis, EarlyView.
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...
