Detection of a Distinct Erythropoietin (EPO) Profile After Isoelectric Focusing in Patients With Familial Erythrocytosis

Drug Testing and Analysis, EarlyView.
A basic EPO IEF profile was identified in patients with familial erythropoiesis linked to mutations in noncoding parts of EPO gene. Comparison of blood and urine EPO profiles from these patients differed from adult wild‐type EPO (WT) and from Eprex‐administered patients. Patients' EPO do not differ from WT EPO after analysis using SDS‐PAGE/SAR‐PAGE. It

Bioactivation and Metabolism of Amino Acid MDMA Prodrugs in Zebrafish Embryos, Human Liver S9, Whole Blood, and Microdosed Human Urine

Drug Testing and Analysis, EarlyView.
Bioactivation and metabolism of MDMA prodrugs: MDMA‐Trp, MDMA‐Lys, MDMA‐Gly showed unique urine screening targets only for MDMA‐Trp, while biomarkers for MDMA‐Lys and MDMA‐Gly consisted of MDMA and known MDMA metabolites. Conversion of amino acid prodrugs to MDMA in pHLS9, zebrafish embryos, and humans. ABSTRACT 3,4‐Methylenedioxymethamphetamine (MDMA)

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

Drug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Filtering Trust: Disclosing the Role of Artificial Intelligence Decreases Trust in Technology, but Does Not Prevent Harm to Body Image After Viewing AI‐Generated Content

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objectives Despite the rapid growth of generative artificial intelligence (AI), virtually no research exists examining the psychological impacts of viewing or interacting with AI‐generated images of people. Additionally, it remains relatively unknown whether informing viewers when images are AI‐generated is an effective way to lessen harm or ...

Microelectrode array scaled for human hippocampal slices

Epilepsia Open, EarlyView.
Abstract Objective Temporal lobe epilepsy (TLE) is characterized by recurrent seizures originating usually from the hippocampus, and approximately one‐third of TLE patients remain refractory to pharmacological interventions. Surgical resection offers a potential cure for refractory TLE cases, with approximately 70% achieving seizure freedom. Still, the

Seismic Assessment Procedure for Exterior Reinforced Concrete Beam–Column Joints With Slab and Transverse Beams

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

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

Fire 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

Fire 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.

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...
