Potential Contamination Cases in Anti‐Doping: Experiences and Practices of 33 Anti‐Doping Organisations

open access: yesDrug Testing and Analysis, EarlyView.
Across 33 Anti‐Doping Organisations (ADOs), 85% reported experiencing at least one contamination‐claim case in 2024–2025, but only 36% operate a standardised process for handling such claims. Dietary supplements were the leading alleged contamination source (76% of ADOs), followed by food (42%) and pharmaceutical products, intimate contact, and other ...

Evidence for the Effectiveness of the Performance Passport Within an Intelligence‐Based Weightlifting Anti‐Doping Programme

open access: yesDrug Testing and Analysis, EarlyView.
Anti‐doping programmes require efficient testing, as biological testing is costly; the Athlete Performance Passport (APP) uses performance data to identify at‐risk athletes alongside APMU and ABP methods. Since the introduction of the steriodal passport in 2014, the APP outperformed APMU (17%) and ABP steroidal profiles (10%) with 30% detection ...

Population‐Stratified Distributions of Post‐Mortem Blood Drug Concentrations: An Epidemiological Framework for Contextual Interpretation

open access: yesDrug Testing and Analysis, EarlyView.
Post‐mortem blood drug concentrations exhibit substantial overlap between deaths in which a drug was implicated and those in which it was not. Analysis of over 58,000 NPSUM cases demonstrates that demographic stratification does not resolve this uncertainty, reinforcing the need for contextual, evidence‐based interpretation rather than concentration ...

Intra‐Individual Variability of Blood and Urinary Steroid Markers and the Response to Codeine Intake in Healthy Men and Women

open access: yesDrug Testing and Analysis, EarlyView.
Short‐term codeine administration (1–3 days) caused individual alterations in Athlete Biological Passport steroid markers, including elevated urinary T/E ratios and decreased serum testosterone concentrations below individual thresholds, despite no significant changes at the group level.

Magneto‐Electrochemical Effect on La‐Doped GaFeO3 as a Supercapacitor Electrode for Energy Storage

open access: yesElectron, EarlyView.
The electrochemical performance of La‐doped Gallium Ferrite (La‐doped GaFeO3 ${\text{GaFeO}}_{3}$) synthesizes via a conventional solid‐state reaction method; this has been studied by the application of an external magnetic fields. ABSTRACT The electrochemical performance of La‐doped GaFeO3 ${\text{GaFeO}}_{3}$ synthesizes via a conventional solid ...

Transcriptomic analysis reveals distinct expression patterns in focal cortical dysplasia

open access: yesEpilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a common cause of drug‐resistant epilepsy in children and adults and exhibits substantial clinical and histopathological heterogeneity. However, morphological classification alone does not fully explain variability in epileptogenicity, disease severity, or treatment response.

Effect of Ammonium Polyphosphate/Silicate Content on the Postfire Mechanics of Epoxy Glass‐Fiber Composites Using Facile Chocolate Bar‐Inspired Structures

open access: yesFire and Materials, Volume 49, Issue 3, Page 329-346, April 2025.
ABSTRACT This study investigates the postfire mechanical properties of epoxy glass‐fiber reinforced composites (EP GFRCs) using increasing concentrations of ammonium polyphosphate (APP) and inorganic silicate (InSi) to modify the char and fire residue.

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

open access: yesFire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.
