The increasing presence of nanomaterials in consumer products has led the scientific community to study environmental fate these contaminants emerging concern. Silver nanoparticles, used mainly for their antibacterial properties, are among most common nanomaterials. Understanding transformations and interactions with living organisms, especially under environmentally relevant conditions that ca...

Nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. The nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. Some samples of Breast muscle, Femora muscle, Heart, Gizzard, Liver, Skin, Spleen, Lung, Kidney and Cloacal feces were collected randomly in slaughter...

Abstract The capture of the Achaemenid treasuries in 331–330 BCE by Alexander Great Persepolis and Susa marked demise 300-year-old Persian Empire advent Hellenistic kingdoms. seized equivalent about 5000 tons silver, which represented accumulated tributes paid subjugated people from Aegean Sea to Indus their rulers. Die studies show that this gigantic amount so-called mix, had been used produce...

In the current work, a new antibacterial bandage was proposed where diamond-like carbon with silver nanoparticle (DLC:Ag)-coated synthetic silk tissue was used as a building block. The DLC:Ag structure, the dimensions of nanoparticles, the silver concentration and the silver ion release were studied systematically employing scanning electron microscopy, energy dispersive X-ray spectroscopy and ...

The murine serum amyloid A1 (SAA1), SAA2, and SAA3 genes are expressed in various tissues in response to acute inflammation. Prolonged expression may be accompanied by amyloid deposition in liver, spleen, and kidney. Shortly before and during deposition, an amyloid-enhancing factor (AEF) can be extracted from these tissues which accelerates amyloid formation when administered with an inflammato...

For a better understanding of the systemic effect of sub-lethal micromolar concentrations of ionic silver on Escherichia coli, we performed a multi-level characterization of cells under Ag+-mediated stress using an integrative biology approach combining physiological, biochemical and transcriptomic data. Physiological parameters, namely bacterial growth and survival after Ag+ exposure, were fir...
