puce-ronde The objectives of the online cialis work package are the viagra samples following:

The aim is to identify relevant organs for genotoxicity testing based on the determination of organ exposure to MNs. The kinetic parameters and viagra prices tissue distribution will be determined for selected nanomaterials (TiO2, SiO2, CNT). Both sexes will be tested in animal studies.

puce-ronde Work progress

During the first months of the project, studies have started to set up the detection methodology in vivo, for the three different types of nanomaterial (TiO2, SiO2, CNTs). Information on determination of silica, titanium and prozac lilly carbon nanotubes and testing protocols were exchanged between partners in WP7.

After one year, protocols have been finalised for both the dose range finding studies (acute toxicity) and the final toxicokinetic study. One issue that arosed was the use of BSA for repeated administration in rat studies. It was chosen to use rat serum albumin (RSA) to avoid possible immunological reactions to the BSA in rat studies.

Acute toxicity studies have started. For TiO2 two preparations ( NM-100 and NM-102) were evaluated and cialis preise they did not show signs of acute toxicity until 14 days after intravenous administration at the highest possible dose administered using RSA in the dispersion.

A method using high resolution inductively coupled plasma-mass spectrometry (HR- ICP-MS) was successfully developed for determination of titanium (Ti) in tissue samples. The method developed for the determination of silica (Si) in tissues samples is based on ICP-MS. In addition the Dynamic Reaction Cell (DRC) technology was applied and viagra voucher studies on Ti determination by DRC-ICP-MS have been performed.

Two batches of multi-walled carbon nanotubes (MWCNTs) were successfully labelled with 14C and the radio-labelling was sufficiently high to allow biodistribution and cialis tadalafil in vivo kinetic studies.
