CANTON — A team of scientists that includes St. Lawrence University biology and psychology professors, plus several recent graduates, has discovered that a specific type of nanoparticle may help alleviate symptoms caused by multiple sclerosis (MS). Their findings were recently published in a leading scientific journal, the university said in a news release issued today.
Karin Heckman, assistant professor of biology, and William E. DeCoteau, associate professor of psychology, from St. Lawrence University were the lead authors on a research paper that examined cerium-oxide nanoparticles and their ability to alleviate the symptoms of MS. The article, entitled “Custom Cerium Oxide Nanoparticles Protect Against a Free Radical Mediated Autoimmune Degenerative Disease in the Brain,” was published recently in ACS Nano, a publication of the American Chemical Society.
Ana Y. Estevez, associate professor of biology and psychology at St. Lawrence, and Joseph S. Erlichman, professor and chair of science and co-chair of the Department of Biology, were also listed as authors in the publication.

Inflation and Insurance Rates: How to Offset the Impact
Many industries have been hit by inflation where it hurts the most, our pockets. Inflation is raising the price of goods and services including food, housing, transportation, and medical care.

Struggling to find the right talent — or keep it? You’re not alone. Across industries, employers are feeling the pressure of a widening skills gap, high turnover, and increasing competition
According to the study, cerium-oxide nanoparticles are both widely used as catalysts in industrial applications and are considered potent antioxidants due to their free radical-scavenging properties. Heckman, DeCoteau and the other authors say in the article that laboratory experiments indicate the particular set of particles located in research at St. Lawrence University have the potential to lessen the symptoms of multiple sclerosis, a neurodegenerative disease, while not causing damage to the liver and spleen of mice.
“St. Lawrence has a unique set of cerium oxide particles,” Heckman, who specializes in infections and autoimmune diseases, said in the news release. “These particles move into the brain to help to provide therapy. Yet, these particles also diminish over time.”
Heckman said development of a pharmaceutical drug is the ultimate goal of the research.
“The question we’re asking now is how can these particles be used therapeutically if they’re packaged in the correct chemical form,” she said. “It can take up to 10 years for a drug to be fully developed, from the initial research to FDA (U.S. Food and Drug Administration) approval. But, yes, that’s the goal.”
The research team also included several recent St. Lawrence graduates, including Jennifer Clauss, Kylie Knapp, Carlos Gomez, Patrick Mullen, Elle Rathbun, Kelly Prime, Jessica Marini, and Jamie Patchefsky .
According to Heckman, the former St. Lawrence students were instrumental in the study, monitoring experiments twice a day and conducting a series of motor tests on the laboratory mice.
Founded in 1856, St. Lawrence University says it is a private, independent liberal-arts institution of about 2,400 students located in Canton.
