Self‐Sustaining Lactate Depletion Nanoplatform Remodels Tumor Microenvironment and Augments Synergistic Photodynamic/Photothermal/Chemodynamic/Starvation Therapy for Eradication of Colon Cancer

Advanced Science, EarlyView.
The HILA nanoplatform integrates HMnO2, LOX, and ICG to orchestrate multimodal therapy (starvation, chemodynamic, photodynamic, and photothermal) for achieving efficient colon cancer eradication. The established HMnO2‐LOX catalytic cycle continuously consumes lactate, acidifys microenvironment, relieves hypoxia, and generats reactive oxygen species ...

A Pancreatitis‐Inspired Trypsinogen Nanoplatform Reprograms Tumor‐Associated Macrophages via NF‐κB for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
Trypsinogen‐loaded nanoparticles reprogram TAMs via NF‐κB/NLRP3, driving M2→M1 conversion and potent phagocytosis to unleash antitumor immunity. ABSTRACT Although reprogramming tumor‐associated macrophages (TAMs) represents a promising therapeutic strategy, approaches that are both precise and safe remain scarce.

Machine Learning‐Enhanced Random Matrix Theory Design for Human Immunodeficiency Virus Vaccine Development

Advanced Intelligent Discovery, EarlyView.
This study integrates random matrix theory (RMT) and principal component analysis (PCA) to improve the identification of correlated regions in HIV protein sequences for vaccine design. PCA validation enhances the reliability of RMT‐derived correlations, particularly in small‐sample, high‐dimensional datasets, enabling more accurate detection of ...

Approximate lethal dose versus median lethal dose in acute toxicity testing of pharmaceuticals

Archives of Toxicology, 1989
The relation between approximate lethal doses (ALD, i.e. the lowest dose at which mortality occurs) and the corresponding median lethal doses (LD50) was investigated in 231 acute toxicity studies in mice and rats. The ALD values were divided into four classes (less than 5 mg/kg, 5-50 mg/kg, 50-500 mg/kg, 500-2000 mg/kg) and the LD50/ALD factors were ...

Persistent brainwave disruption and cognitive impairment induced by acute sarin surrogate sub-lethal dose exposure

Toxicology, 2021
International audienceWarfare neurotoxicants such as sarin, soman or VX, are organophosphorus compounds which irreversibly inhibit cholinesterase. High-dose exposure with nerve agents (NA) is known to produce seizure activity and related brain damage ...
