T1- and diffusion tensor-based fractal dimension of white and grey matter in multiple sclerosis

Frontiers in Neurology
IntroductionMultiple sclerosis (MS) changes brain microstructure even at early disease stages, with changes detectable in normal-appearing white matter (NAWM) and grey matter (GM).

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Membranes Studied by NMR Spectroscopy*

, 1999
The use of NMR spectroscopy to study the structures and dynamics of membrane systems is described. The principal nuclei used are 1H, 2H, 13C and 31P. Both oriented and nonoriented systems can be investigated. In addition, peptides and proteins embedded in membranes can be studied. © 1999 Elsevier Ltd All rights reserved.

Solid-state NMR on larger biomolecules

, 2011
In the last years, remarkable progress has been made to probe molecular structure of biological systems using Magic Angle Spinning solid-state NMR (ssNMR). Prominent examples relate to research areas that have remained challenging to classical structural

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Modular Control of PEG‐Poly(2‐Oxazoline) Co‐Assembly Enables Tunable Aggregate Properties for Intraocular Pressure Management

Advanced Healthcare Materials, EarlyView.
A thermo‐responsive poly(2‐oxazoline)‐based injectable formulation is developed to modulate intraocular pressure (IOP) in both normal and hypotonic eyes. By adjusting the PEG content, the aggregation behavior is finely tuned, enabling IOP elevation without long‐term deposition.

Structural basis of RNA recognition and dimerization by the STAR proteins T-STAR and Sam68

Nature Communications, 2016
Sam68 and T-STAR are members of the STAR family of proteins, which regulate various aspects of RNA metabolism. Here, the authors reveal structural features required for alternative splicing regulation by these proteins.

Protein dynamics detected in a membrane-embedded potassium channel using two-dimensional solid-state NMR spectroscopy

, 2010
We report longitudinal 15N relaxation rates derived from two-dimensional (15N, 13C) chemical shift correlation experiments obtained under magic angle spinning for the potassium channel KcsA-Kv1.3 reconstituted in multilamellar vesicles.
