Phytoavailability of silver at predicted environmental concentrations: does the initial ionic or nanoparticulate form matter?

The anti-tumor efficacy of nanoparticulate form of ICD-85 versus free form

Biodegradable polymeric nanoparticles (NPs) have been intensively studied as a possible way to enhance anti-tumor efficacy while reducing side effects. ICD-85, derived from the venom of two separate species of venomous animals, has been shown to exhibit anti-cancer activity. In this report polymer based sodium alginate nanoparticles of ICD-85 was used to enhance its therapeutic effects and redu...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Reformism Revisited: Does Form of Government Matter?

Molecular Control of TiO2-NPs Toxicity Formation at Predicted Environmental Relevant Concentrations by Mn-SODs Proteins

With growing concerns of the safety of nanotechnology, the in vivo toxicity of nanoparticles (NPs) at environmental relevant concentrations has drawn increasing attentions. We investigated the possible molecular mechanisms of titanium nanoparticles (Ti-NPs) in the induction of toxicity at predicted environmental relevant concentrations. In nematodes, small sizes (4 nm and 10 nm) of TiO₂-NPs ind...

environmental effects of gol-e-gohar iron ore mine on groundwater of the area

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
