Background: Persistent and mobile organic compounds (PMOC) are of great concern for water quality and human health. The recent improvement and availability of high-resolution mass spectrometry in combination with liquid chromatography have widely expanded the potential of analytical workflows for their detection and quantitation in water. Given their high polarity, the detection of some PMOC requires alternative techniques to reversed-phase chromatography, such as hydrophilic interaction liquid chromatography (HILIC) and supercritical fluid chromatography (SFC).

Nanocomposites that mimic the characteristics of enzymes, commonly as nanozymes, can function as an efficient sensing material with high selectivity towards the targeted biological macromolecule. These nanozymes overcome of the challenges that arise when using natural enzymes as sensing material. This study presents a novel nanozyme, Copper Selenite (CuSeO) nanoparticles mounted on f-CNF, to electrochemically determine a potential cardiovascular biomarker, Glutathione (GSH).

This work aims to optimize encapsulation of Zanthoxylum schinifolium essential oil (ZSEO) in microcapsule to enhance its stability and slow-release capability. Herein, the ZSEO microcapsules stabilized by bacterial cellulose nanofibrils/whey protein isolate (BCNFs/WPI) complexes and modified by cinnamaldehyde (CA) were successfully prepared via spray drying. The microcapsules formed by 1.

Introduction: The US supply disruption of surgical irrigation fluids in September 2024 prompted the need for fluid conservation and potential deferral of urology procedures. We characterized fluid use in common endoscopic procedures to articulate recommendations for irrigation fluid stewardship and case prioritization during fluid shortages.
Methods: We reviewed case volumes and irrigation fluid use for endoscopic urological procedures at our institution during January-September 2024.
Neuro-computational simulation of blood flow loaded with gold and maghemite nanoparticles inside an electromagnetic microchannel under rapid and unexpected change in pressure gradient.

In cardiovascular research, electromagnetic fields generated by Riga plates are utilized to study or manipulate blood flow dynamics, which is particularly crucial in developing treatments for conditions such as arterial plaque deposition and understanding blood behavior under varied flow conditions. This research predicts the flow patterns of blood enhanced with gold and maghemite nanoparticles (gold-maghemite/blood) in an electromagnetic microchannel influenced by Riga plates with a temperature gradient that decays exponentially, under sudden changes in pressure gradient. The flow modeling includes key physical influences like radiation heat emission and Darcy drag forces in porous media, with the flow mathematically represented through unsteady partial differential equations solved using the Laplace transform (LT) method.
