Methodological guidelines for the characterization of polysaccharide helical structures
Abstract Polysaccharide chain conformation is a critical determinant of their physicochemical and biological properties; however, reliable identification remains a significant challenge due to the inconsistent structural evidence yielded by conventional analytical techniques.

Integrated scRNA‐seq and spatial multiomics provide single‐cell and spatial insights into the neuroprotective effects of NGR1, a clinically validated bioactive compound from Panax notoginseng. NGR1 was associated with a shift in microglial transcriptional states away from ischemia‐associated pro‐inflammatory Adam8hi microglia and toward the protective ...

Perspectives of High‐Resolution Mass Spectrometry in Soil Science
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Calibration‐Free Single‐Frame Super‐Resolution Fluorescence Microscopy
A deep learning framework reconstructs super‐resolved fluorescence images from a single dense camera frame, without any prior calibration or knowledge of the microscope. Trained solely on synthetic data, it generalizes across imaging setups and conditions.

Abstract Background Cognitive impairment is a prevalent and debilitating feature of Parkinson's disease (PD). Increasing evidence from postmortem and in vivo positron emission tomography imaging studies supports cholinergic dysfunction in PD. There is, however, little evidence regarding the influence of the structural integrity of cortical cholinergic ...

Influence of THF as Internal‐Donor on Ziegler‐Natta Polyethylene Catalysts
Ziegler–Natta catalysts remain widely applied due to robustness, handling ease, and cost‐effectiveness. To support further optimization, we examine how internal donors such as tetrahydrofuran influence catalyst performance and polymer characteristics.

ABSTRACT Purpose To compare the dependence on b‐value of the spherical harmonic powers for the diffusion MRI signal in white matter to theoretical predictions from the stick model of water diffusion within axons. Methods Diffusion MRI data were acquired at 3 T in three healthy adults with 10 b‐value shells (b = 1000–10 000 s/mm2) and 64 directions per ...
