Label‐Free Holographic Imaging Flow Cytometry With Deep‐Learning‐Based Detection and Classification of Thousands of Cells Per Second

open access: yesCytometry Part A, EarlyView.
ABSTRACT We present a new end‐to‐end neural network approach for real‐time biological cell detection and classification via label‐free quantitative imaging flow cytometry based on digital holography, offering a comprehensive representation of cellular structures without the need for chemical cell staining. In contrast to previous studies, our method is

Traceable Refractive Index Measurements of Liquids to Standardize Extracellular Vesicle Flow Cytometry

open access: yesCytometry Part A, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are potential disease biomarkers released by cells into body fluids. Flow cytometers measure EV concentrations within their size detection range. These size ranges can be quantified by relating the arbitrary units of measured light scattering signals to the optical diameter of EVs with Mie theory.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Coherence evaluation and first demonstration of multi-contrast X-ray computed tomography on NanoTerasu BL09W with an X-ray Talbot interferometer. [PDF]

open access: yesJ Synchrotron Radiat
Coherence properties were evaluated and multi‐contrast X‐ray computed tomography was demonstrated using an X‐ray Talbot interferometer on the NanoTerasu beamline BL09W. The results confirm the high spatial coherence and imaging performance of the source, paving the way for advanced X‐ray phase imaging.We report on the coherence evaluation of the ...

Construction of a clickable probe‐based protein chip platform for discovering covalent mIDH1 inhibitors from natural medicinal extracts

open access: yesiMeta, EarlyView.
In this study, we develop a flexible Ccc‐Chip (protein microarray + bioorthogonal click chemistry) for high‐throughput screening of natural covalent active molecules from medicinal plant extracts, identifying flavokawain C from Piper methysticum Forst as a novel covalent mIDH1 inhibitor.

Inhibition of ferroptosis by microbiota‐derived lithocholic acid underlies the intestinal radioprotection of a host defensin‐derived oligopeptide

open access: yesiMeta, EarlyView.
AT9(C/G), an oligopeptide derived from human defensin 5, enriches Bifidobacterium pseudolongum and increases lithocholic acid (LCA) levels in the intestine. Reduced levels of LCA link to increased severity of ionizing radiation‐induced intestinal injury (IRIII) in both murine and clinical studies.

Targeting DGKα/PA axis inhibits tumor immune evasion and augments sensitivity to immunotherapy in gastrointestinal cancers

open access: yesiMeta, EarlyView.
Immune checkpoint inhibitors (ICIs) have shown promising antitumor efficacy in certain types of solid tumors. However, the efficacy of ICIs remains unsatisfactory owing to the dysregulation of signaling pathways in local tumor tissues. Here, we reveal that diacylglycerol kinase α (DGKα)‐derived phosphatidic acid (PA) directly binds to nuclear factor‐κB

Amplification of Light‐Ultrasound Interaction in a Pi‐Shifted Fiber Bragg Grating for Enhanced Ultrasonic Sensitivity

open access: yesLaser &Photonics Reviews, EarlyView.
By precisely engineering the geometry of a fiber‐based optical resonator, the interaction between confined light and external ultrasound waves is significantly amplified without sacrificing light confinement, boosting the ultrasound detection sensitivity beyond 0.5 mPa/√Hz.
