To study the phenomenon of disease without books is to sail an uncharted sea, while to study books without patients is not to go to sea at all.

Sir William Osler (1849 – 1919)

Dr. van Breemen Named One of the Top 10 Analytical Science Experts in North America in 2020

In The Analytical Scientist, Dr. Richard van Breemen was named one of the winners of the Power List of 2020. Ten scientists were picked from each continent, and each has a story to tell.

Congratulations, Dr. van Breemen!

Goodbyes and Welcome!

Congratulations to Dr. Daniel Nosal and Dr. Luying Chen on achieving your doctorate. Daniel will continue as a postdoctoral researcher at our laboratory. Luying is starting her new job as a Senior Scientist at Novartis Global Drug Development.

We wish you success in your future endeavors.

Margaret Redick is joining us for Fall Semester of 2020. She will be working on a project to do high-throughput screening of natural product extracts and combinatorial libraries using magnetic microbead affinity selection screening (MagMASS).

Welcome to Oregon State University, Maggie!


Hops-based Supplements and Women’s Health

An article on Everyday Health features the work by our laboratory group on Hops Dietary Supplement. Our study shows no significant drug interactions in women taking hops to control hot flashes.


Celebrating Linus Pauling Day

In celebration of Linus Pauling Day, Dr. van Breemen was interviewed by Dr. John Westerdahl on LifeTalk Radio.

Linus Pauling is one of the most famous scientists born and raised in Oregon. February 28th is Linus Pauling’s birthday, which the Governor declared as a local holiday in the state of Oregon.

Excerpt of Dr. van Breemen from Health & Longevity

Linus Pauling was a career long academician and teacher, and it is the mission of the Linus Pauling Institute to train the next generation of scientists in the prevention of diseases of aging – a tradition that Pauling created with this Institute. The full interview is available for download.

  • Dr. John Westerdahl is a nutritionist and board certified anti-aging health practitioner. He is also the radio host for the program Health & Longevity.

A landmark literature of 2019 featured in The Analytical Scientists magazine

When Luying was developing an assay to study how botanical dietary supplements may affect drug metabolism, she identified and reported a widespread presence of drugs in samples of “supposedly” pure human serum. These include: caffeine, alprazolam (an anti-anxiety medicine), and dextromethorphan (an cough suppressant).

The Truth About Transfusions

Dr. Catherine Fenselau, Distinguished University Professor Emeritus, University of Maryland

Her measurements were made following FDA guidance for pharmacological studies, using stable isotope labeled internal standards and ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) on a Shimadzu triple quadrupole mass spectrometer.

She tested 18 lots of human serum from North American sources – all of which contained caffeine (as high as 250 ng/mL), 13 contained alpraxolam, and 8 contained dextromethorphan. Two individual donors had to be recruited to abstain from caffeinated foods and beverages to complete her assay validation.
