Liquid Atmospheric Pressure MALDI (LAP‐MALDI) Mass Spectrometry: A Versatile Tool for the Characterization of Synthetic Polymers

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Liquid atmospheric pressure matrix‐assisted laser desorption/ionization (LAP‐MALDI) mass spectrometry (MS) has previously been applied to the analysis of biopolymers such as peptides, proteins, and DNA, producing ESI‐like multiply charged analyte ions.

Probiotic Stability and Antihypertensive Activity of Peptides in Aguamiel Syrup‐Fortified Milk Protein Fermented by Lacticasebacillus rhamnosus GG

open access: yeseFood, Volume 7, Issue 4, August 2026.
This study evaluates the impact of aguamiel syrup on a synbiotic fermented dairy product, focusing on antihypertensive peptide release and Lacticaseibacillus rhamnosus GG survival. While metabolic parameters remained unchanged, aguamiel syrup enhanced bioactive peptide production and antihypertensive activity (45.3%), suggesting its potential as a ...

Restriction‐Weighted Q‐Space Trajectory Imaging (ResQ): Toward Mapping Diffusion‐Time Effects With Tensor‐Valued Diffusion Encoding in Human Prostate Cancer Xenografts

open access: yesNMR in Biomedicine, Volume 39, Issue 8, August 2026.
Tensor‐valued diffusion MRI enables microstructure characterization but can be confounded by the presence of restricted diffusion. We introduce ResQ, a framework that incorporates restriction weighting into q‐space trajectory imaging and we evaluate it in a longitudinal study of prostate cancer xenografts treated by external radiotherapy. ResQ revealed

Logarithmic spirals in 2d perfect fluids

open access: yes
We study logarithmic spiraling solutions to the 2d incompressible Euler equations which solve a nonlinear transport system on $\mathbb{S}$. We show that this system is locally well-posed in $L^p, p\geq 1$ as well as for atomic measures, that is ...

Working So Hard: Double‐Stranded RNAs That Can Perform Both Gene Activation and Gene Silencing

open access: yesChemBioChem, Volume 27, Issue 13, 14 July 2026.
Working so hard: STING saRNAs are capable of not only entering the nucleus to induce subsequent target gene upregulation, but can also act as an siRNA to perform gene silencing. Chemical modifications in saRNA guide and passenger strands affect the strength of gene activation or gene silencing activity.
