Article Abstract
Chocolate is widely consumed worldwide and its market grows every year, with emerging demands for new high-quality products. However, this product is susceptible to contamination with polycyclic aromatic hydrocarbons (PAHs), representing a risk for humans. In this study, a methodology for the evaluation of benzo[a]pyrene, benzo[a]anthracene, benzo[b]fluoranthene and chrysene in chocolate by high performance liquid chromatography was validated. The occurrence, dietary exposure, and health risks of 4 PAHs in 38 commercial chocolate samples was investigated. The methodology demonstrated adequate accuracy and precision, with recovery (95.25 %-108.12 %) and relative standard deviation (0.14 %-5.83 %). Benzo[a]pyrene and the ∑4 PAHs concentrations varied between 1.09 and 10.42 µg/kg and 8.38-41.58 µg/kg, respectively. The results of risk assessment suggest low potential health risk for chocolate consumers, considering the margin of exposure (MOE) and the incremental life cancer risk (ILCR) values.

A multi-omics recovery factor predicts long COVID in the IMPACC study.
J Clin Invest
September 2025
The University of Texas at Austin, Austin, United States of America.
Background: Following SARS-CoV-2 infection, ~10-35% of COVID-19 patients experience long COVID (LC), in which debilitating symptoms persist for at least three months. Elucidating biologic underpinnings of LC could identify therapeutic opportunities.
Methods: We utilized machine learning methods on biologic analytes provided over 12-months after hospital discharge from >500 COVID-19 patients in the IMPACC cohort to identify a multi-omics "recovery factor", trained on patient-reported physical function survey scores.
Antithrombin-binding heparan sulfate is ubiquitously expressed in epithelial cells and suppresses pancreatic tumorigenesis.

3-O-sulfation of heparan sulfate (HS) is the key determinant for binding and activation of Antithrombin III (AT). This interaction is the basis of heparin treatment to prevent thrombotic events and excess coagulation. Antithrombin-binding HS (HSAT) is expressed in human tissues, but is thought to be expressed in the subendothelial space, mast cells, and follicular fluid.

Engineering functional exosomes represents a cutting-edge approach in biomedicine, holding the promise to transform targeted therapy. However, challenges such as achieving consistent modification and scalability have limited their wider adoption. Herein, we introduce a universal and effective strategy for engineering multifunctional exosomes through cell fusion.

Major depressive disorder affects millions worldwide, yet current treatments require prolonged administration. In contrast, ketamine produces rapid antidepressant effects by blocking spontaneous N-Methyl-D-Aspartate (NMDA) receptor signaling, which lifts the suppression of protein synthesis and triggers homeostatic synaptic plasticity. Here, we identify a parallel signaling pathway involving metabotropic glutamate receptor 5 (mGluR5) that promotes rapid antidepressant-like effects.
