Precision Digital Dispensing of Patterned Picoliter Quantities of Test Material onto Apical Surfaces of Human 3D-Reconstructed Airway Tissues
March 30, 2017There is an increasing need for researchers to understand the dynamic aspects of inhaled tobacco product exposure. Available 3D human reconstructed airway tissues (RHuA) provide researchers with a more physiological platform that offers apical and basal compartments for flexibility in modelling relevant exposures. We have tested the Tecan D300 digital dispenser as potential technical solution to deliver precise amounts of very small vehicle droplets to coat the apical surface of an available RHuA....

The Use of Human 3D Reconstructed Airway Cultures for Tobacco Product Evaluation: Precision Low-Volume Exposures at the Apical Site
January 10, 2017With a mandate to evaluate the dynamics of pulmonary exposure to inhaled materials such as tobacco-based products, researchers are employing complex, human, three-dimensional pulmonary models. Human reconstructed airway (RHuA) tissues present a platform that more closely resembles airways in vivo. Grown at the air–liquid interface (ALI), RHuA tissues offer apical and basal compartments that allow flexibility in modeling physiologically relevant exposures and provide sampling location-specific results.

Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology
October 18, 2016This one-hour webinar, led by IIVS Director of Quality and Compliance, introduces some of the concepts of Good Laboratory Practices (GLPs) designed to promote study and data integrity within an in vitro toxicology framework. Applying these concepts within your own laboratory should aid in production of robust, repeatable studies. View Slides...
Next Generation Tobacco Products
August 24, 2016IIVS has a long-standing history of working with various industries to help establish or utilize in vitro models for the prediction of risk and the assessment of products under development. With the Food and Drug Administration extending its authority to all tobacco products (including e-cigarettes, cigars, and hookah) the tobacco industry is faced with the task of assessing product safety for product development and regulatory submission. Further, the manufacture of tobacco products may entail risk to workers that come in...
Fragrance & Flavors
August 24, 2016Exposure to fragrance chemicals is most commonly by direct skin contact. Allergic contact dermatitis (ACD) to fragrance ingredients is most often caused by cosmetic products, such as perfumes, deodorants, and aftershave products. Cosmetic fragrance ingredients should be assessed for exposure damage including skin sensitization (ACD), phototoxicity, skin irritation (irritant contact dermatitis), and respiratory irritation and sensitization. At IIVS, we have pre-clinical testing programs to address each of these endpoints to ensure the safety of fragrance ingredients.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
