Using the PBK Model to Predict Risk Metrics: MOIE, MOS

Systems PBK/PD Modeling of 4-Hydroxyphenylpyruvate Dioxygenase Inhibition

Amanda HoldanNews, Webinars

 Our webinar on PBPK Modeling features speakers Dr. Steven Webb and Dr. David Cowie from Syngenta. Together, they will share models to assess how Tyrosine aminotransferase (TAT) catalyzes the conversion of tyrosine to accumulation of hydroxyphenylpyruvic acid (HPPA) and how its activity varies among mammalian species. Species differences also exist in the ability to utilize alternative pathways for tyrosine catabolism …

Genetic Toxicolgoy and NAMs using Respiratory Tract Tissues

Integrating computational tools and human cell-based NAMs for human-relevant risk assessments

Amanda HoldanNews, Webinars

Our first September 2024 webinar focuses on novel methods to assess relevant risk in humans with Les Recio, PhD, DABT, ATS, and Rasim Barutcu, PhD. We believe these approaches are a positive and proven way forward for expediting research and reducing the use of animals. While we do not offer a training course for integrating these tools, we do offer …

Dr Alexandra Noël speaks about using in vitro assays to assess the electronic nicotine delivery system aerosols.  What you’ll learn:  Overview of EVALI outbreak and harm caused. Known effects of e-cigarettes. How Air-liquid interface (ALI) physiologically relevant in vitro models can be used to assess the pulmonary effects associated with exposure to inhaled e-cig aerosols containing nicotine. Watch the Recording …

3D Liver models

3D cell culture models & their role in enhancing genotoxicity testing approaches for nano- and advanced-materials

Amanda HoldanNews, Webinars

It was an honor to have Professor Shareen Doak with us to discuss her groundbreaking research. Her research on New Approach Methodologies (NAMs) and overcoming limitations of OECD Test Guidelines for nanomaterials (NMs) testing is leading edge brought up a lot of great questions. The link to the recording is below.    What you’ll learn:  The need to adapt existing …
