ToxAIcology – the future of toxicology is AI

Amanda Holdan News, Webinars

Artificial Intelligence (AI) is impacting all types of work, including toxicology. Dr Hartung will discuss how to move toxicology to a more holistic and integrated paradigm using AI and how AI plays a role in setting the direction of “Toxicology for the 21st Century 2.0” in future decades.   What you’ll learn:  Sources of Big Data for toxicology and various AI …

Physiologically based pharmacokinetic modeling as a data analysis and study design tool – case studies in nonlinear pharmacokinetics

Amanda Holdan News, Webinars

We just had a wonderful talk from Dr. Dan Hoer. Dr Hoer is a physical scientist with the US Environmental Protection Agency, Office of Pesticide Programs. His talk will focus on non-linear PBPK modeling, and the advantages offered by this approach.  What you’ll learn:  Important advantages of PBPK modeling over statistical methods that are often restricted to bimodal distinctions of …

(R)Evolution in Validation: Establishing Scientific Confidence in NAMs

Amanda Holdan News, Webinars

Nicole Kleinstreuer, PhD, the director of the NTP Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) and the executive director of the congressionally mandated Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). spoke on July 18th, 2023. Dr. Kleinstreuer discussed a topic very important to our industry; a framework comprising five essential elements to establish scientific …

A Source to Outcome Approach for Inhalation Risk Assessment: The Importance of Collaboration

Amanda Holdan News, Webinars

Doug Wolf, DVM, PhD, discusses the creation and use of the Souce-to-Outcome framework, a new NAM incorporating a novel mathematical procedure developed to estimate the human equivalent concentration (HEC) for inhalation risk assessment based upon the relevant aerosol characterization, respiratory dosimetry modeling, and endpoints derived from an in vitro assay using human respiratory epithelial tissue.  What you’ll learn:  Introduction to …

Applications of Physiologically Based Pharmacokinetic (PBPK) Modeling in Nanomedicine, Food Safety and Human Health Risk Assessment and Roles of Artificial Intelligence (AI) Approaches in these Areas

ScitoVation News, Webinars

In this presentation, Dr. Zhoumeng Lin introduces how we develop physiologically based pharmacokinetic (PBPK) models of drugs, environmental chemicals and nanoparticles for applications in nanomedicine, food safety, and human health risk assessments. He presents his recent studies to illustrate each application. Dr. Zhoumeng Linalso introduces a new physiological parameter database for PBPK modeling in food-producing animals, including cattle, swine, sheep, …

The Need for Increased Maturity in the Risk Assessment Ecosystem

ScitoVation Blog

by Dr. Jean Orelien Last year, the US EPA declared they would phase away from animal testing by 2035. Reaching this milestone will require the maturity of the risk assessment ecosystem. By maturity, I mean new roles need to be assumed along with improved interactions and (stronger) bonds within and between group as well as new entities. In this post, I share a …

Physiologically Based Pharmacokinetic (PBPK) Modeling of Central Nervous System

ScitoVation Blog

by Marjory Moreau, Ph.D. I have worked in PBPK modeling for many years and until a few months ago, I never had to deal with the brain compartment. Well, I had a brain compartment in several of my models, but I never really thought about the blood brain barrier and all the transporters involved in protecting or bringing compounds into the brain until recently. I …

What are NAMs?

ScitoVation Blog

by Sage Corzine     If you got pumped up about NAMs in a toxicology webinar, tried to find more information on Google, and got redirected to the North American Menopause Society, you are not alone. NAMs or New Approach Methodologies are a vital and growing part of chemical hazard and risk assessment research. Here are a few fun facts …

The Frontier of Aerosol Safety Testing with In Vitro and in Silico Methods

ScitoVation Blog

  by Scott Slattery In May and June of this year, the annual Webinar Series on Inhalation Toxicity Testing was co-hosted by The US EPA, the PETA Science Consortium International, Syngenta, and Unilever. The nine webinars presented over three days provided an excellent look at current progress in the area of non-animal inhalation toxicity testing approaches. The talks covered the breadth of the field, addressing in …
