Tuning the Enzymatic Activity of Aqueous Phase Separation‐Based PEI‐PSS Membranes

open access: yesMacromolecular Chemistry and Physics, EarlyView.
Polyelectrolyte membranes were prepared by APS through the complexation of PEI and PSS. Lysozyme and laccase were incorporated to give enzymatic functions. This work demonstrates the possibility of tuning the enzymatic activities of APS‐produced membranes by changing the polyelectrolyte mixing ratio and enzyme concentration.

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Hematopoietic Stem Cell Transplantation in an International Cohort of Colony Stimulating Factor‐1 Receptor (CSF1R)‐Related Disorder

open access: yesMovement Disorders, EarlyView.
Abstract Background Colony stimulating factor‐1 receptor (CSF1R)‐related disorder (CSF1R‐RD) is an autosomal dominant, rapidly progressive, demyelinating disease leading to death usually within a few years. Because of the central role of CSF1R in microglia functions, allogeneic hematopoietic stem cell transplantation (HSCT) has been suggested as a ...
