Influence of Different Washing Hair Procedures in the Quantitative Determination of THC and THCCOOH

Drug Testing and Analysis, Volume 18, Issue 6, Page 777-784, June 2026.
Different hair decontamination protocols significantly affect THC quantification, with marked analyte loss—particularly after aqueous‐organic washing—whereas THCCOOH remains stable. These findings highlight the risk of misinterpretation and the need for standardized washing procedures in hair analysis.

Sensory Properties and Aroma Compound Profiles of Pea Protein Isolates in Relation to High Hydrostatic Pressure and High‐Pressure Homogenization Treatments

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Flavor profiles of untreated pea protein isolate (light green, solid line) compared to High Pressure Homogenization (HPH) treated (dark blue, dash‐dot line) and High Hydrostatic Pressure (HHP) treated pea protein isolates (dark green, dashed line). Samples were described as mainly pea‐like/bean‐like, flour‐like/cereal‐like, bitter, fatty, and sour ...

Validation of Noninvasive Cutaneous Carotenoid Measurements as Nutritional Biomarker Across Body Composition Groups

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Cutaneous carotenoid measurements obtained non‐invasively by reflection spectroscopy (Veggie Meter and Biozoom) showed strong correlations with plasma carotenoid concentrations measured by HPLC in women across different BMI categories (Veggie Meter rs(151) = 0.697 and Biozoom rs(151) = 0.650, both p < 0.001).

Quantitative Measurement of Extracellular Vesicle‐Sized Particles in Blood Plasma by Laser Diffraction Without an Extraction Process: A Proof‐of‐Concept Study in Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Laser diffraction enabled rapid measurement of extracellular vesicle‐sized particles in fasting plasma without an extraction process. In this proof‐of‐concept study, particle concentrations were higher in atrial fibrillation than in controls, suggesting the potential of this simple approach for biomarker assessment.

Urea provides an important nitrogen source for microbial populations in an ultraoligotrophic sea

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Urea is an organic nitrogen (N) compound directly utilized by both heterotrophic prokaryotes and some photoautotrophs. Reports of either ambient urea concentrations or urea uptake rates from the ultraoligotrophic eastern Mediterranean Sea are lacking. We investigated urea distribution and uptake in the upper water column in the Levantine basin during ...
