Article Synopsis
- This study introduces a new high-performance liquid chromatography (HPLC) method with amperometric detection for accurately measuring silybin, a key component in nutricosmetics derived from Silybum marianum.
- It details a solid sample preparation technique using ultrasound-assisted extraction (UAE) to effectively isolate silybin before analyzing it chromatographically.
- The developed method achieves efficient separation of silybin A and B in under 20 minutes, demonstrating a low detection limit and high recovery rate, making it superior to previous methods for silybin analysis.
Sesquiterpene lactones (SLs) such as parthenolide (PTL) and dehydroleucodine (DhL) selectively kill cancer cells without exerting normal tissue toxicity, potentially due to presence of α-methylene-γ-lactone (αMγL) fragment. We hypothesize that the addition of an azido group to the αMγL fragment of PTL or DhL further augments their anticancer properties as well as radiation sensitivity of cancer cells. Azido-SLs containing the azido group at the C14 methyl position of PTL (i.

- Researchers have created highly microporous carbons from pistachio shells, achieving high surface areas (up to 3300 m²/g) and pore volumes using a CO2 activation process.
- Different methods were tested to transform the biomass into carbon materials with varying structures and reactivities towards CO2, while optimizing pore development.
- The most effective technique involved hydrothermal carbonization, which boosts carbon yield and porosity, and higher activation temperatures can speed up the process without losing pore quality.
Background: Identifying potential factors correlated with the sustained presence of antibodies in plasma may facilitate improved retrospective diagnoses and aid in the appraisal of pertinent vaccination strategies for various demographic groups. The main objective was to describe the persistence of anti-spike IgG one year after diagnosis in children and analyse its levels in relation to epidemiological and clinical variables.
Methods: A prospective, longitudinal, observational study was conducted in a university reference hospital in the Metropolitan Region of Barcelona (Spain) (March 2020-May 2021).
With the rapidly increasing demand for lithium ion batteries (LIBs), recycling the metals found in spent cathodes is mandatory to both alleviate shortages resulting from the mining of natural metal ores and manage the disposal of spent LIBs. The use of deep eutectic solvents (DESs) for metals recovery from spent cathodes of LIBs (e. g.
