A Hypoxia‐Responsive Near‐Infrared Phosphorescence Nanoprobe for High‐Sensitive Detection of Tumor Cells and Imaging of Colorectal Cancer In Situ

Aggregate, EarlyView.
We have successfully developed a hypoxia‐responsive near‐infrared phosphorescent probe, Ir‐PEG. This nanoprobe demonstrates high sensitivity, water solubility, and deep‐tissue penetration. It remains specifically activatable even in the hypoxic intestinal environment, facilitating high‐contrast imaging of orthotopic colon cancer.

Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

A Hybrid Transfer Learning Framework for Brain Tumor Diagnosis

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel hybrid transfer learning approach for brain tumor classification achieves 99.47% accuracy using magnetic resonance imaging (MRI) images. By combining image preprocessing, ensemble deep learning, and explainable artificial intelligence (XAI) techniques like gradient‐weighted class activation mapping and SHapley Additive exPlanations (SHAP), the ...

An in vivo assay for osteoclast activity using mouse calvaria

Animal Models and Experimental Medicine, EarlyView.
This study describes a novel method for measuring osteoclast‐mediated bone resorption in vivo using a mouse model. Localized injection of RANKL in a basement membrane matrix above the cranium induced osteoclast‐mediated bone resorption. Utilizing micro‐computed tomography and a semiautomated three‐dimensional analysis program, osteoclast resorption pit

Molecular imaging is non-inferior to adrenal vein sampling for diagnosing surgically curable primary aldosteronism: a prospective, within-patient study

Efficacy and Mechanism Evaluation
Background Primary aldosteronism due to a unilateral aldosterone-producing adenoma is a common cause of hypertension. This can be cured or greatly improved by adrenal surgery.
