Quantitative Determination and Stability of Trace Levels of Oxytocin in Human and Rhesus Macaque Urine by LC-MS/MS. [PDF]
ABSTRACT Oxytocin (OT) quantification in biological samples is vital for understanding its role in social behavior, emotion, and brain development in humans and animals. Urinary OT analysis has gained attention but is challenging due to variability in matrix effects, background interference, low concentrations, and stability concerns.

A Novel Microfluidic System for 3D Epidermis and Full-Thickness Skin Growth for Nanoparticle Safety Assessment. [PDF]
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven

Ecological and Health Risks of Polycyclic Aromatic Hydrocarbons in Particulate Matter in Chinese Cities. [PDF]
Abstract During the first two decades of the 21st century, the level of polycyclic aromatic hydrocarbon (PAH) pollution in urban atmospheric particulate matter (PM) in China significantly increased. By combining data from more than 6,695 individual samples covering 89 typical cities (population > 0.5 million people) across China, this study focuses on ...
