Engineered extracellular vesicles for precision renal therapy: Bioengineering strategies and clinical translation

open access: yesInterdisciplinary Medicine, EarlyView.
Engineered extracellular vesicles (EVs) offer a versatile platform for kidney‐targeted therapy. This review summarizes bioengineering strategies, including cargo loading, surface modification, biomimetic fabrication, and biomaterial integration. We highlight translational challenges and propose future solutions to accelerate the clinical application of

Essential Oils from Humulus Lupulus scCO2 Extract by Hydrodistillation and Microwave-Assisted Hydrodistillation

open access: yesMolecules, 2018
Two different extraction methods were used for a comparative study of essential oils obtained from the Humulus lupulus scCO2 (sc-supercritical) extract: microwave-assisted hydrodistillation (MAHD) and conventional hydrodistillation (HD). As a result, the

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Qualitative and quantitative evaluation of glucosinolates in cruciferous plants during their life cycles [PDF]

open access: yes, 2004
Glucosinolates produced by Brassica species were investigated in relation to biofumigation, a term used to describe the effects some allelochemicals, including glucosinolate derived products, may have on soil-borne pathogens or other herbivores.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
