Tight Junctions (TJ) are important components of paracellular pathways, and their destruction enhances vascular permeability. Resolvin D1 (RvD1) is a novel lipid mediator that has treatment effects on inflammatory diseases, but its effect on inflammation induced increase in vascular permeability is unclear. To understand whether RvD1 counteracts the(More)
Aqueous nanocolloids of poorly soluble materials were produced via sonicated layer-by-layer (LbL) encapsulation with polycation / polyanion shells. Synergy of simultaneous breaking powder particles with ultrasonication and coating them with polycations allowed for the production of 150-200 nm diameter polyelectrolyte coated nanoparticles with sufficient(More)
BACKGROUND A variety of inflammatory mediators and effector cells participate together in acute lung injury, and lead to secondary injury that is due to an inflammatory cascade and secondary diffuse lung parenchyma injury. Inflammation is associated with an oxidative stress reaction, which is produced in the development of airway inflammation, and which has(More)
In this review we will overview novel nanotechnological nanocarrier systems for cancer therapy focusing on recent development in polyelectrolyte capsules for targeted delivery of antineoplastic drugs against cancer cells. Biodegradable polyelectrolyte microcapsules (PMCs) are supramolecular assemblies of particular interest for therapeutic purposes, as they(More)
The sonication-assisted layer-by-layer (SLBL) technology was developed to combine necessary factors for an efficient drug-delivery system: (i) control of nanocolloid size within 100 - 300 nm, (ii) high drug content (70% wt), (iii) shell biocompatibility and biodegradability, (iv) sustained controlled release, and (v) multidrug-loaded system. Stable(More)
A new method of nanoparticle formulation for poorly water-soluble materials was demonstrated for curcumin. The drug was dissolved in organic solvent that is miscible with water (ethanol), and drug nucleation was initiated by gradual worsening of the solution by the addition of an aqueous polyelectrolyte assisted by ultrasonication. Curcumin crystals of(More)
PURPOSE Ketamine is commonly used in pediatric anesthesia but may cause neurodegeneration in young brains. The aim of the study is to use an animal model to characterize the role of microRNA 137 (miR-137) in ketamine-induced neurodegeneration in neonatal hippocampus. METHODS Young Sprague-Dawley Rats (1 month old) was systemically administrated with(More)
A risk assessment model for water shortage was constructed from the risk analysis method based on the information diffusion theory. The application of this model was demonstrated in the city of Yiwu in Zhejiang Province, China. The study indicates that the present model is more stable and effective when compared with the traditional model, based on(More)
