As a condition for your use of the Biomedical AMS Resource, it is expected that you will pursue publication of the results within one year of successful completion of the studies. All publications must acknowledge the participation of the Resource and contain the following acknowledgment statement:

Work performed (partially) at the National Resource for Biomedical Accelerator Mass Spectrometry (AMS), which is operated at LLNL under the auspices of the U.S. Department of Energy under contract DE-AC52-07NA27344. The Resource is supported by the National Institutes of Health (NIH), National Institute of General Medical Sciences (NIGMS), and Biomedical Technology Research Resources (BTRR) under grant P41GM103483.

Copies of preprints should be sent to the Resource Administrative Contact, Nanette Sorensen, for review by Resource collaborator or staff. After publication, an electronic and two hard-copy reprints need to be sent to the Resource Administrative Contact.

For NIH reporting purposes, we require that all publications be deposited in Pubmed Central. If deposition is not done by the journal, the primary or corresponding author should deposit the papers. If needed, contact the Resource Administrative Contact, Nanette Sorensen, for assistance.

Bomb-pulse dating of collagen extracted from cerebral aneurysms showed that the structural proteins of aneurysms are unlike cerebral arteries and that the carbon in the collagen is less than 4 years old. Subjects with the risk factors of hypertension, smoking, or history of cocaine use experienced carbon turnover less than 2 years. The work was featured on the June 2014 cover of Stroke.

Identification of the GABAA receptor target of tetramethylenedisulfotetramine was reported using 14C-AMS competitive binding assays and mathematical modeling in collaboration with John Casida at UC Berkeley and Bruce Hammock at UC Davis. Identifying the receptor site is helpful in designing antidotes to GABA channel toxins.
