Flow Injection Inductively Coupled Plasma-Mass Spectrometry With Ultrasonic Nebulizer for the Quantification of Trace Elements in Seawater: An Innovative Method Targeting Cadmium, Cobalt, Lead, Manganese, Molybdenum, Tin, Uranium, and Vanadium. [PDF]

open access: yesJ Sep Sci
ABSTRACT The accurate determination of trace elements in seawater is essential for environmental monitoring and the study of oceanic biogeochemical processes. However, traditional analytical techniques often face limitations due to the ultra‐trace concentrations of metals and the high salinity of seawater, which introduces significant matrix effects ...

Decoding adipose-brain crosstalk: Distinct lipid cargo in human adipose-derived extracellular vesicles modulates amyloid aggregation in Alzheimer's disease. [PDF]

open access: yesAlzheimers Dement
Abstract INTRODUCTION Obesity is a major modifiable risk factor for Alzheimer's disease (AD), but the mechanistic link between peripheral metabolic dysfunction and AD progression remains unclear. Adipose‐derived extracellular vesicles (EVs) may penetrate the brain and alter lipid homeostasis, contributing to neurodegeneration.
