Fragment-based discovery of TopBP1 inhibitors integrated with AI-driven molecular docking

DNA topoisomerase IIβ-binding protein 1 (TopBP1) converges on multiple oncogenic pathways, e.g., Rb, p53, and PI3K/Akt, which are hallmarks of most cancer progression. However, the lack of structural...

Structural anisotropy in celery stalks by microscopic MRI and polarized light microscopy

Structural anisotropy of celery stalks was studied using T2 anisotropy in microscopic MRI (μMRI) and supplemented by quantitative polarized light microscopy (PLM) at optical resolutions. Parenchyma,...

Truncated enhanced constraint for low-rank plus sparse in cardiac dynamic MRI reconstruction

Cardiac dynamic MRI has been widely used in cine and perfusion imaging, in which low-rank and sparse priors play an important role in reconstructing dynamic images with high temporal and spatial resolution...

Single-scan ultra-selective probing on targeted components from overlapped NMR spectra

Benefitting from the non-invasive and quantitative detection property, liquid NMR spectroscopy shows broad applications in the identification, separation, and structural determination of chemical substances...

Femtotesla atomic magnetometer for zero- and ultralow-field nuclear magnetic resonance

Zero- and ultralow-field nuclear magnetic resonance (ZULF NMR) has experienced rapid development and provides an excellent tool for diverse research fields ranging from materials science and quantum...

Adaptive k-space learning and high-dimensional subsets embedding for parallel MRI reconstruction

Magnetic resonance imaging (MRI) inherently requires considerable time for data acquisition, but obtaining multi-contrast MRI data further prolongs this process, thereby increasing susceptibility to...

The rise of NMR-integrated fragment-based drug discovery in China

Nuclear magnetic resonance (NMR) spectroscopy is an indispensable tool to probe weak protein-ligand interactions, which are key to the hit identification and hit-to-lead evolution in fragment-based...

Dynamic nuclear polarization and chemically induced hyperpolarization: Progress, mechanisms, and opportunities

Nuclear magnetic resonance (NMR) spectroscopy is a powerful and broadly used spectroscopic technique for characterizing molecular structures and dynamics. Yet the power of NMR is restricted by its inherently...

Cryoporometry for short T2 samples: A T1 filter method applied to battery electrode characterization

The pore size distribution is often an important parameter for transport processes in porous media. Cryoporometry experiments can provide such data in the meso and macropore size up to 1 μm providing...

A magnetically compatible, arbitrary positioning system for accurate spatial mapping of magnetic fields for shimming studies in MRI

After the fabrication of magnetic resonance superconducting magnets, the magnetic field inhomogeneity needs to be accurately measured for subsequent shimming. However, conventional measurement methods...

19F NMR study of proteins with parallel incorporation of multiple fluorinated aromatic amino acids

Although the parallel incorporation of fluorinated aromatic amino acids (FAAAs) into proteins has been explored since 2010, the corresponding 19F NMR investigation has been lacking to date. To assess...

Rigid and stable nitroxide spin label for high-resolution distance measurements on proteins by DEER experiments

The distance distributions between two site-specifically anchored spin labels in a protein, measured by pulsed electron-electron double resonance (PELDOR or DEER), provide rich sources of structural...

FlexCENT: A frequency-flexible CEST imaging network combining frequency offset encoding and three-dimensional U-Net

This study proposes a deep learning-based method termed frequency-flexible chemical exchange saturation transfer (CEST) imaging network (FlexCENT), which enables robust CEST quantification across variable...

Mean pore diameters of 3D printed micro-capillaries using the matrix pencil method

The matrix pencil method (MPM) is an approach for quantitative analysis of the multi-exponential time-domain signals from relaxation and diffusion NMR experiments. In contrast to other signal processing...

Spin-echo measurements for capillary rheometry at low field

A single spin-echo, acquired in the presence of a constant magnetic field gradient, has a phase proportional to the average velocity of the sample and an amplitude determined by the distribution of...

Passive water exchange between multiple sites can explain why apparent exchange rate constants depend on ionic and osmotic conditions in gray matter

Porous materials, such as biological tissue, often have heterogeneous microstructures where imbibed fluid experiences distinct environments on short timescales, but can exchange among different environments...

Iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) for evaluation of early bone mass changes in ageing osteoporosis patients

This study explored the application value of iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) technology in the early diagnosis of ageing osteoporosis...

A hybrid denoising method for low-field nuclear magnetic resonance data

Low-field nuclear magnetic resonance (NMR) has broad application prospects in the exploration and development of unconventional oil and gas reservoirs. However, NMR instruments tend to acquire echo...

An amphiphilic peptide with unnatural amino acids as an alignment medium for RDC measurements

The multiple oligopeptides have been regarded as promising alignment media due to their structural diverseness and tendency for self-assembly in solution. Herein, an assembled amphiphilic peptide alignment...

Applications of nuclear magnetic resonance in exploring structure and energy storage mechanism of supercapacitors

Supercapacitors, comprising electrical double-layer capacitors (EDLCs) and pseudocapacitors, are widely acknowledged as high-power energy storage devices. However, their local structures and fundamental...

Measurement of protein non-covalent interactions in buffer and cells

Nuclear magnetic resonance (NMR) serves as a powerful tool for studying both the structure and dynamics of proteins. The NOE method, alongside residual dipolar; coupling, paramagnetic effects, J-coupling,...

Unraveling boron-organic template interactions in [B, Al]-ZSM-5 zeolite using solid-state NMR spectroscopy

Organic structure directing agents (OSDAs), such as tetrapropylammonium (TPA) cations, serve as crucial templates for the formation of zeolite frameworks. These organic molecules interact with inorganic...
