Integrative Phosphoproteomic Profiling Reveals Stage‐Specific Signalling and Metabolism in Equine Melanocytic Neoplasm

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Equine melanocytic neoplasms (EMN) are aggressive tumours characterised by high metastatic potential and limited therapeutic options available. However, the molecular mechanisms underlying their progression remain poorly understood. This study therefore presents the integrative phosphoproteomic analysis of EMN tissue, with the aim of ...

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

NSAID ingestion augments training‐induced muscle hypertrophy and differentially affects muscle mRNA expression, but not strength gains, in trained men

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the impact of NSAID ingestion on resistance exercise training‐induced changes in muscle morphology, function and gene networks relative to placebo ingestion in trained males. Abstract Non‐steroidal anti‐inflammatory drugs (NSAIDs) are widely overused in sports.

Comprehensive Quantitative Urinary Steroid Profiling of 29 Steroids Using Liquid Chromatography‐Tandem Mass Spectrometry

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Steroids are critical for numerous physiological processes; disruption in their metabolism is associated with numerous endocrine disorders. Steroid quantification is essential to improve the understanding and diagnosis of these pathologies. Historically, urinary steroid profiling has been performed using low‐throughput gas chromatography mass ...

Statistical Discrimination of Urinary Steroid Biomarkers in the Athlete Biological Passport: A Novel Approach to an Abnormal Steroid Profile Score (ASPS)

Drug Testing and Analysis, Volume 18, Issue 5, Page 608-618, May 2026.
The study developed a single Abnormal Steroid Profile Score (ASPS) to improve interpretation of the Athlete Biological Passport steroid module. Using Bayesian modelling and logistic regression, biomarker patterns from laboratory and doping control data successfully discriminated between doped and clean individuals, with improved classification ...
