This article shows the successful exposition exposure of cigarette smoke on two different Ames bacteria strains by using the Vitrocell exposure system including the VC10 smoking robot. Conventional 1 mg tar commercial cigarettes (CC1), 1R5F reference cigarettes (University of Kentucky,Lexington, KY, USA), and 3R4F reference cigarettes (University of Kentucky) were compared with a prototype heated cigarette (HC).

International Nanotoxicology Congress

June 1 – 4, 2016. Boston, Massachusetts, USA.

The 2016 International Nanotoxicology Congress will take place in Boston, Massachusetts, USA, on June 1 – 4, 2016. This conference is the 8th in a continuing series of international meetings that are broadly focused on nanotoxicology, one that began in Boston in 2006. Thus, it is fitting that we return to this beautiful and historic city for our 10th anniversary meeting.

VITROCELL® User Group Meeting 2016

11 March 2016, Hilton New Orleans Riverside, USA prior to the Society of Toxicology 55th Annual Meeting and ToxExpo

After a successful User Group Meeting 2015 in the EUROPA-PARK in Germany, International scientists from Europe, Japan and USA followed the invitation of VITROCELL® Systems to the 2016 User Group Meeting.

It offered an excellent opportunity to discuss the latest developments of VITROCELL®, to exchange experiences in working with VITROCELL® devices and to meet fellow researchers. The meeting took place prior to the international Society of Toxicology 55th Annual Meeting and ToxExpo – one of the largest international conferences related to toxicology.

The focus of the event was to present new routes dosimetry, to give an update on VITROCELL’s participation in major European research programs related to nanoparticles as well as the presentation of new products for 2016.

This study has demonstrated that the modified CDS, a novel method that mimics the conditions for the lung surfactant, is a useful bioassay to assess the acute effects of dry powder aerosols on the lung. The in vitro method, based on the constrained drop surfactometer, different Turbuhaler as well as empty Turbuhaler filled with albumin or lactose were tested. A quartz crystal microbalance was fitted in the chamber to estimate the dose of the deposited particles.

BEAS-2B, A549, and MucilAir cells were exposed to CeO2 particles and are cultured at air–liquid interface. LDH, cytokine analysis, gene expression analyses, HO-1 analyses and Comet assay were used for evaluation. Cell responses in the MucilAir model exposed via air to CeO2 were minimal compared to those of the cell lines.
