Biofilms are composed of bacterial cells encased in a self-synthesized, extracellular polymeric matrix. Poly-beta(1,6)-N-acetyl-d-glucosamine (PNAG) is a major biofilm matrix component in phylogenetically diverse bacteria. In this study we investigated the physical and chemical properties of the PNAG matrix in biofilms produced in vitro by the gram-negative porcine respiratory pathogen Actinoba...

Abstract Overexposure to food colorants above the allowed daily intake (ADI) level can provoke hyperactivity and other disturbed behaviors especially in children. Two new methods were developed separate five synthetic colorants, which Tartrazine (E102), Sunset Yellow (E110), Allura Red (E129), Carmoisine (E122), Brilliant Blue (E133). They are labeled on a large variety of commercial products E...

In this paper, we propose a simple procedure to obtain multi-walled carbon nanotubes (MWCNTs) decorated with TiO2–Ag nanoparticles (MWCNT–TiO2–Ag). The MWCNTs were via combined functionalization –OH and –COOH groups polymer-wrapping technique using poly(allylamine)hydrochloride (PAH). TiO2-modified Ag synthesized the Pechini method mixture of acetylacetonate-modified titanium (IV) isopropoxide ...

Synthetic food colors are important ingredients in the industry. These synthetic colorants azo dyes, majorly acidic nature such as Allura red and Tartrazine. They present sweets, carbonated drinks, meat products, candies to attract consumers. This review article is an attempt explain adverse effects of dyes their association with oral cavities cardiovascular disorders. (azo dyes) have staining ...

Water pollution from the fashion industries containing dyes has become a major source of water pollution. These anthropogenic contaminated waters directly enter irrigation and drinking systems, causing irreversible environmental damage to human health. Nanomembrane technology attracted extensive attention remove these toxic chemicals but new approaches are still required for improving removal e...

• PANI-TNT nanocomposite was used for modification of pure PVDF membrane. Phase inversion method to develop PVDF-PANI-TNT nanofiltration membranes. Developed membranes show excellent self-cleaning properties in filtration processes. Water flux, hydrophilicity and antifouling improved by adding PANI-TNTs. In this research article, the (polyvinylidene fluoride)–PANI (polyaniline)–titanium nanotub...

BACKGROUND In endothelial cells, activation of the AMP-activated protein kinase (AMPK) has been linked with anti-inflammatory actions but the events downstream of kinase activation are not well understood. Here, we addressed the effects of AMPK activation/deletion on the activation of NFκB and determined whether the AMPK could contribute to the anti-inflammatory actions of nitric oxide (NO). ...
