Hubbard J, Hoffman M, Ellis S, Sobolesky P, Smith B, Suhandynata R, et al.
J Anal Toxicol . 2021 Jun; 45(8):820-828. PMID: 34185831
Proving driving under the influence of cannabis (DUIC) is difficult. Establishing a biomarker of recent use to supplement behavioral observations may be a useful alternative strategy. We determined whether cannabinoid...

Alomary A, Fitzgerald R, Purdy R
Int Rev Neurobiol . 2001 Oct; 46:97-115. PMID: 11599313
In this chapter, we review techniques used for the analysis of neurosteroids and discuss the advantages and disadvantages of each method. Because radioimmunoassay (RIA) procedures are well known, we focus...

Vallee M, Rivera J, Koob G, Purdy R, Fitzgerald R
Anal Biochem . 2000 Nov; 287(1):153-66. PMID: 11078595
A simplified method for the quantitative analysis of neurosteroids in rat plasma and brain is described. The method uses negative chemical ionization gas chromatography/mass spectrometry and involves the synthesis of...

Chen Z, Fitzgerald R, Averna M, Schonfeld G
J Biol Chem . 2000 Jul; 275(42):32807-15. PMID: 10893242
Nonphysiological truncations of apolipoprotein (apo) B-100 cause familial hypobetalipoproteinemia (FHBL) in humans and mice. An elucidation of the mechanisms underlying the FHBL phenotypes may provide valuable information on the metabolism...

Azzazy H, Duh S, Fitzgerald R, McLawhon R, Rosenthal M, Christenson R
Ann Clin Biochem . 1999 Aug; 36 ( Pt 4):438-46. PMID: 10456205
We evaluated a second generation, qualitative, whole blood rapid assay for cardiac troponin T (cTnT), which employs a more cardio-specific troponin T mouse monoclonal capture antibody. Using quantitative cTnT enzyme-linked...

Fitzgerald R, Rivera J, Herold D
Clin Chem . 1999 Aug; 45(8 Pt 1):1224-34. PMID: 10430788
Background: Currently the rate-limiting step for mass spectrometric analysis of drugs in biological samples is sample preparation. Many gas chromatography/mass spectrometry (GC/MS) methods are specific for a certain class of...

Frankel S, Fitzgerald R, Sackier J
Surg Endosc . 1998 Aug; 12(9):1137-40. PMID: 9716767
Objectives: To determine whether filters, regularly used as part of the insufflator tubing during laparoscopic surgery, trap microbial and particulate matter from CO2 tanks, thus preventing passage from one patient...

Fitzgerald R, ONeal C, Hart B, Poklis A, Herold D
J Anal Toxicol . 1997 Nov; 21(6):445-50. PMID: 9323524
Recent innovations in mass spectrometry (MS) have led to the development of instruments with increased capabilities, smaller footprints, and relatively low cost. The traditional MS in most toxicology laboratories is...

Pediatr Dermatol . 1997 Mar; 14(2):93-7. PMID: 9144692
The diagnosis of cutaneous T-cell lymphoma in patients under 20 years of age is extremely rare. We report five patients diagnosed before 20 years of age who illustrate the striking...
