Kim A, Yu B, Dueker S, Shin K, Kim H, Ahn H, et al.
Clin Pharmacol Ther . 2017 Feb; 102(3):537-546. PMID: 28214288
C-labeled YH4808, a novel potassium-competitive acid blocker, was intravenously administered as a microtracer at 80 μg (11.8 kBq or 320 nCi) concomitantly with the nonradiolabeled oral drug at 200 mg...

Dueker S, Lin Y, Buchholz B, Schneider P, Lame M, Segall H, et al.
J Lipid Res . 2000 Nov; 41(11):1790-800. PMID: 11060348
We present a sensitive tracer method, suitable for in vivo human research, that uses beta-[(14)C]carotene coupled with accelerator mass spectrometry (AMS) detection. Using this approach, the concentration-time course of a...

Dueker S, Lin Y, Jones A, Mercer R, Fabbro E, Miller J, et al.
Anal Biochem . 2000 Jul; 283(2):266-75. PMID: 10906248
Whole blood folate level is a superior indicator of folate nutritional status than serum/plasma level. Problems with and lack of confidence in results of current whole blood folate assays have...

Lin Y, Dueker S, Burri B, Neidlinger T, Clifford A
Am J Clin Nutr . 2000 Jun; 71(6):1545-54. PMID: 10837297
Background: Blood beta-carotene and vitamin A responses to oral beta-carotene are variable in humans. Some individuals are characterized as responders and others as low- or nonresponders. A better understanding of...

Au T, Zhang Y, Arjomand A, Lin Y, Dueker S, Ho Y, et al.
Comp Biochem Physiol C Pharmacol Toxicol Endocrinol . 1999 Jul; 123(1):45-52. PMID: 10390055
Localized folate deficiency may be a risk factor for cancer. Since, folate binding proteins (FBP) and reduced folate carrier proteins (RFC) mediate cellular transport of folate, we compared FBP concentrations...
6.
Buchholz B, Arjomand A, Dueker S, Schneider P, Clifford A, Vogel J
Anal Biochem . 1999 May; 269(2):348-52. PMID: 10222009
Long-term physiologic tracing of nutrients, toxins, and drugs in healthy subjects is not possible using traditional decay counting of radioisotopes or stable isotope mass spectrometry due to radiation exposure and...
7.
Dueker S, Jones A, Clifford A
Adv Exp Med Biol . 1998 Oct; 445:363-78. PMID: 9781401
Improved instrumentation and the increased availability of labeled compounds have democratized the application of isotope-dilution (tracer) methodology in nutrient metabolism. Still, the most challenging aspects of tracer experimentation reside in...

Clifford A, Arjomand A, Dueker S, Schneider P, Buchholz B, Vogel J
Adv Exp Med Biol . 1998 Oct; 445:239-51. PMID: 9781393
Folate is an essential nutrient that is involved in many metabolic pathways, including amino acid interconversions and nucleotide (DNA) synthesis. In genetically susceptible individuals and populations, dysfunction of folate metabolism...

Lin Y, Burri B, Neidlinger T, Muller H, Dueker S, Clifford A
Am J Clin Nutr . 1998 May; 67(5):837-45. PMID: 9583839
The reportedly inconsistent antioxidant protective effect of beta-carotene on plasma LDL may depend on LDL's beta-carotene concentration. We measured carbonyl production by CuSO4-challenged LDL from nine healthy women living at...

Dueker S, Mercer R, Jones A, Clifford A
Anal Chem . 1998 Apr; 70(7):1369-74. PMID: 9553494
The role of beta-carotene in chemoprevention of cancers and other chronic diseases generated controversy when subpopulations taking beta-carotene supplements showed increased mortality in clinical trials. Determination of the dynamics of...
