2nd Annual Jamie DeRita Memorial Animal Protection Symposium

July 20, 2021


The Jamie Derita Memorial Animal Protection Symposium will be held on July 20th, 2021 on Zoom. 

This symposium honored the life of Jamie DeRita, who passed away in June 2020. Jamie was CAAT's event coordinator from 2012-2018, and was known to many of our friends and colleagues for her tireless work on our many meetings, conferences and symposia over the years.

Jamie was famous throughout the Maryland shelter and animal welfare communities as someone who could not say no to helping any animal that needed a home. She was known to regularly pick up animals she saw in her daily travels, and to work non-stop to find them perfect homes. Her CAAT family will honor her with a series of presentations about our deep relationship with animals and adoption of lab animals, with brief testimonials from family and friends interspersed throughout the event. Her family has also started a fundraiser to secure the future of her four children. Please consider donating any amount here.

A GoFundMe account (see below) has been set up to support Jamie's children—please consider contributing.

Thomas Hartung and Sonja von Aulock Profiled in ASBMB Today

Excerpted from ASBMB Today: The Member Magazine of the American Society for Biochemistry and Molecular Biology

When Thomas Hartung was a medical student in Germany in the early 1990s, he interviewed a 35-year-old mother of three who was waiting for a liver transplant. Without the transplant, she would die, and Hartung recalls thinking, “I would do any experiment on mice if I could save this woman.”

Animal experiments have been the foundation of most medical advances in the past century, including vaccination technologies, cancer treatments and new treatments for neurological diseases. According to a 2007 report, “Medical Advances and Animal Research,” most Nobel laureates in physiology or medicine used animals in their research, considering it unfortunate but necessary.

The ethical obligation of researchers to reflect on their use of animal models is outlined in a set of principles known as the three R’s, which most nations use as a guideline for laws governing animal experiments. Zoologists William Russell and Rex Burch introduced the three R’s — replacement, reduction and refinement — in “The principles of humane experimental technique”in 1959. The three R’s stipulate that researchers first determine whether their animal experiment can be replaced with a nonanimal experiment. If this is not possible, experimenters should strive to reduce the number of animals they use. Finally, the experiment should be refined to minimize animal suffering.

Hartung, who successfully replaced animal experiments with cell cultures in his graduate research, is now director of the Center for Alternatives to Animal Testing, or CAAT, at the Johns Hopkins Bloomberg School of Public Health. He believes the biggest step researchers can take toward reducing animal experimentation is a change in mindset; animal models have been useful for so long, it’s hard to believe that there are better models out there, even if the data exists.
