Researchers track perfluorinated chemicals in the body

Author: Jessica Sieff

Graham Peaslee

New research in the journal Environmental Science & Technology Letters shows scientists have developed a method to track perfluorinated alkyl substances (PFAS) in the body. PFAS are potentially toxic chemicals found in stain-resistant products, nonstick cookware, fire-fighting foams and — most recently — fast food wrappers.

For the first time, scientists radiolabeled PFAS with a fluorine isotope used in nuclear medicine to track the accumulation of these chemicals in the mouse models. Some of these chemicals have already been linked to kidney cancer, testicular cancer, low birth weight, hypertension, decreased fertility and thyroid problems. Read More

Tuberculosis: The Disease of Antiquity

Author: Jessica Sieff

In the time it takes to read this article, half a dozen people will have died from tuberculosis (TB).

It is a cruel and persistent killer, claiming 1.8 million lives each year, an estimated 200,000 of which are children, according to the World Health Organization (WHO).

Considering the gravity of those numbers, it’s even more alarming to know that many cases go unreported.

“Tuberculosis is the most prevalent infectious disease that the world has seen, based on the number of people infected and the number of resulting fatalities,” said Jeff Schorey, George B. Craig Jr. Professor in the Department of Biological Sciences at the University of Notre Dame. “It is the single leading cause of death by an infectious organism.”

Jeff Schorey, a world-renowned expert with pioneering work on the role of exosomes in infectious diseases, has been studying mycobacterial disease for almost two decades.

World Tuberculosis Day marks the official discovery of Mycobacterium tuberculosis by Dr. Robert Koch on March 24, 1882. But the infectious disease is considered to date back thousands of years. It causes death worldwide, primarily affecting low- and middle-income countries. Pulmonary TB can spread with a cough, infecting anyone in the vicinity. Patients require access to first-line drugs and face a six-month regimen of multiple antibiotics. An incomplete course of antibiotics poses an increased risk for developing multi-drug-resistant TB.

Shaheen 3MT Finals Click for larger image

Nine University of Notre Dame graduate students will compete for prize money while attempting to explain their research in three minutes during the third annual Shaheen Three Minute Thesis competition on Monday (March 27). Known as 3MT, the goal of the competition is for Ph.D. students from Science, Engineering and Arts and Letters to cultivate the ability to explain their research, including both breadth and significance, in a language appropriate to an audience containing both specialists and non-specialists, all within three minutes.

Notre Dame’s 3MT finals will take place from 4 to 6 p.m. in the Jordan Auditorium in the Mendoza College of Business. A reception will follow the competition, which is free and open to the public.

The competitors will address a live audience and panel of judges with a single static slide accompanying their presentations. In addition to monetary prizes, the Notre Dame students are competing to claim a spot in the Midwestern Association of Graduate Schools 3MT regional competition in Indianapolis on April 7.

Advancing from the College of Science are doctoral candidates Julia Beck from biochemistry, Elizabeth Loughran from integrated biomedical sciences and Read More

WHO's list of Priority Pathogen's and Antibiotic Research in the Warren Center

Author: Richard Taylor

February 28, 2017 – For the first time, the World Health Organization (WHO) published a list of “priority pathogens” which constitute a current and extreme threat to human health. WHO is seeking to promote new efforts in the discovery and development of new antibiotics to address a growing threat of antibiotic resistance.

Wholist

Research encompassing the fundamental mechanism of antibiotic resistance and bacterial biofilms as well as the discovery of new antibiotics and the development of new tools to aid in their discovery have a rich history at the University of Notre Dame and researchers within the Warren Family Center for Drug Discovery & Development.

Shahriar Mobashery’s team recently published research on the regulation of the peptidoglycan protective layer of Gram-negative bacteria such as Pseudomonas aeruginosa. In collaboration with Mayland Chang, Mobashery also discovered two new classes of antibacterials, the oxadiazoles and quinazolinones. Read More
