Inflammatory bowel diseases: pathological mechanisms and therapeutic perspectives.

Molecular biomedicine
Inflammatory bowel diseaseĀ (IBD) is a heterogeneous group of disorders characterized primarily by chronic relapsing intestinal inflammation, encompassing Crohn's diseaseĀ (CD) and ulcerative colitisĀ (UC), affecting individuals across age groups with v...

Integrating AI-assisted SERS Biosensing and Photoactivated Antibacterial Therapy in Au@CuSe for Combating Multidrug-Resistant Bacteria.

Analytical chemistry
The escalating global crisis of multidrug-resistant (MDR) bacteria demands innovative strategies that bypass conventional antibiotic limitations. This study introduced a multifunctional Au@CuSe core-shell nanoplatform integrating artificial intellige...

The Redox Properties of Polyphenols and Their Role in ROS Generation for Biomedical Applications.

Angewandte Chemie (International ed. in English)
Polyphenols, particularly catechols, represent a significant class of compounds characterized by their versatile physicochemical and biological properties, sourced from both natural origins and industrial by-products. This review highlights their cri...

Label-free robotic mitochondrial biopsy.

Science advances
Robotic micromanipulation has advanced cellular probing, yet achieving precise, minimally invasive intracellular operations without fluorescent labeling remains challenging. Fluorescent techniques often cause photodamage and cytotoxicity and interfer...

Backtracking metabolic dynamics in single cells predicts bacterial replication in human macrophages.

Nature communications
Accurately tracking dynamic state transitions is crucial for modeling and predicting biological outcomes, as it captures heterogeneity of cellular responses. To build a model to predict bacterial infection in single cells, we have monitored in parall...

Overcoming the tumor microenvironment in pancreatic cancer barrier-specific nanoparticle drug delivery.

Nanoscale
Pancreatic cancer is one of the most lethal malignancies, largely due to the formidable pathophysiological barriers presented by its tumor microenvironment (TME). These include metabolic stress, such as acidosis and elevated reactive oxygen species; ...

Kinetic and Mechanistic Discrepancies of Single/Dual-Atom Nanozymes Drive a Triple-Channel Sensing Array for Machine Learning-Assisted Antioxidant Discrimination.

Analytical chemistry
Current colorimetric sensing arrays for antioxidant detection often struggle with discrimination due to cross-reactive signals from individual nanozymes. These signals are typically modulated by external factors such as pH or chromogenic substrates, ...

FAM46B inhibits CS-induced oxidative stress and ferroptosis in bronchial epithelial cells via KLHL24.

International immunopharmacology
BACKGROUND: Chronic obstructive pulmonary disease (COPD), mainly caused by cigarette smoke (CS), is a global health concern. Ferroptosis is recognized as a key driver of COPD progression, yet its underlying mechanisms are unclear. This study aimed to...

Exploring the role of oxidative stress in retinal vein occlusion: an updated and comprehensive review on the pathophysiology and treatment perspectives.

International ophthalmology
INTRODUCTION: Retinal vein occlusion (RVO) represents a prevalent cause of vision impairment within retinal vascular diseases. Although hypoperfusion and inflammation are recognized pathogenic contributors, emerging evidence highlights oxidative stre...

Machine Learning-Assisted Real-Time Inflammation Monitoring and Optimal Treatment of Diabetic Wounds Based on a Ratiometric Fluorescent Sensing Peptide Hydrogel.

Nano letters
Managing inflammation in diabetic chronic wounds remains a major clinical challenge, primarily due to the lack of real-time monitoring techniques. To address this issue, we developed a peptide hydrogel capable of simultaneously monitoring the inflamm...
