Lipid droplet profiling during neutrophil differentiation by stimulated Raman scattering microscopy

Biotechnology Progress, EarlyView.
Abstract Lipid droplets (LDs) are dynamic organelles that serve as metabolic hubs and emerging regulators of immune cell fate. Although LDs have been implicated in immune regulation, how LD metabolism is remodeled during neutrophil differentiation and how stage‐specific LD dynamics shape mature neutrophil function remain poorly defined.

Transcriptome and proteome analyses reveal divergent adaptive strategies in nasopharyngeal epithelial cells and nasopharyngeal carcinoma cells under ultra‐low background radiation

Deep Underground Science and Engineering, EarlyView.
This study demonstrates that the ultra‐low background radiation environment in deep underground laboratories significantly inhibits the proliferation of both normal nasopharyngeal epithelial cells (HNEPC) and nasopharyngeal carcinoma cells (HNE‐1) cells, with malignant cells exhibiting higher sensitivity.

Clinical Relevance of BACH1 Expression in Non–Small Cell Lung Cancer

International Journal of Cancer, EarlyView.
ABSTRACT BTB and CNC homolog 1 (BACH1) is a redox‐sensitive transcription factor implicated in tumor progression, metabolic reprogramming, and therapy resistance in several cancers. However, its prognostic significance and role in therapy resistance in non–small cell lung cancer (NSCLC) remain unclear.

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

A Semi‐Automated Microfluidic Platform Employing Machine Learning Analysis to Study Adhesion Kinetics in Acute Myeloid Leukemia

Microscopy Research and Technique, EarlyView.
We have developed a semi‐automated shear flow platform using bright‐field optics and a machine‐learning analysis algorithm to dissect tumor‐microenvironment interactions. The algorithm quantifies the extent of adhesion at the single‐cell level and delivers consistent results within minutes instead of hours, facilitating high‐throughput analysis ...

An Electromagnetically-Driven Piezoresistively Sensed CMOS MEMS Scanning Mirror for Projection Display

Proceedings, 2017
Bi-axial MEMS scanning mirrors are considered the key component for applications like laser scanning projectors and Lidars. Most studies have shown fabricated devices driven by open-loop operation without sensing, making it difficult to meet the ...

Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

Laser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.
