Nano‐Backpack Engineered Probiotics with Reactive Oxygen Species–Responsive Tungsten Release for Synergistic Therapy of Inflammatory Bowel Disease

Advanced Science, EarlyView.
An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...

Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

Advanced Science, EarlyView.
Chronic diabetic wounds are hindered by a “dual trap” of biofilm resistance and hyperinflammation. A mesoporous catalytic‐adsorptive nano‐regulator is developed to dismantle this barrier through simultaneous eDNA degradation and LPS sequestration. By silencing TLR4/9‐mediated signaling, the platform clears resilient pathogens and reprograms the immune ...

A Pathology‐Instructed Theranostic Platform with Mechanoadaptive and ROS‐Powered Nanobreathing Functions for Precision Myocardial Repair

Advanced Science, EarlyView.
We developed a pH responsive theranostic serum albumin hydrogel named BST, functionalized with MRI and CT probes and loaded with mitochondria targeted CAT‐SOD nanogels, that rapidly self repairs and mechanically stabilizes the infarcted myocardium, releases therapeutic nanogels and albumin under hypoxia induced acidosis to clear mitochondrial ROS ...

Electrokinetic properties of endotoxins and their significance for the limulus amoebocyte lysate test

, 1986
The electrokinetic properties of the endotoxins of Escherichia coli and Serratia marcescens have been examined. Both endotoxins are negatively charged, with the zetapotential being increased by the presence of cations whose relative influence resembles ...

Plant Virus Immunotherapy for HPV‐Associated Oropharyngeal Squamous Cell Carcinoma

Advanced NanoBiomed Research, EarlyView.
Cowpea mosaic virus (CPMV) nanoparticles are safe and potent cancer immunotherapy candidates with strong immunomodulatory activity. CPMV activates innate immunity, which in turn drives adaptive immune responses and promotes durable, systemic antitumor effects.

Tunable Regional Targeting of Self‐Assembling Peptide Nanomaterials in Acute Myocardial Infarction

Advanced NanoBiomed Research, EarlyView.
In a rat model of acute myocardial infarction, intravascular delivery of peptide nanofibers with a collagen‐targeting peptide bound to the infarct vasculature while globular peptide nanoparticles penetrated into the infarct area. This study demonstrated that size, shape, and surface chemistry of nanomaterials control the delivery location within the ...

144. Endotoxins.

, 2011
Endotoxins are components of the outer membrane of Gram-negative bacteria and are a biologically active component in most organic dusts. Occupational exposure occurs primarily in the agriculture industry and related sectors.
