Does pH paper accurately reflect gastric pH?
- E. Dobkin, A. Valcour, +6 authors N. Yeston
- Medicine
- Critical care medicine
- 1 September 1990
The testing of gastric pH in the ICU has become the standard of care for most critically ill patients. It has been demonstrated that maintaining a gastric pH of greater than 3.5 confers protection… Expand
Evaluation of a kinetic method for prostatic acid phosphatase with use of self-indicating substrate, 2,6-dichloro-4-nitrophenyl phosphate.
- A. Valcour, G. Bowers, R. Mccomb
- Chemistry, Medicine
- Clinical chemistry
- 1 June 1989
The purity, spectral characteristics, and rate of nonenzymatic hydrolysis of 2,6-dichloro-4-nitrophenyl phosphate (DCNPP) were determined. Rates of DCNPP hydrolysis by prostatic acid phosphatase… Expand
Internal proton magnetic resonance probes for pH titration of proteins

Proton nuclear magnetic resonance spectroscopy of human transferrin N-terminal half-molecule: titration and hydrogen-deuterium exchange.
- A. Valcour, R. Woodworth
- Chemistry, Medicine
- Biochemistry
- 2 June 1987
The binding of Ga(III) to the proteolytically derived N-terminal half-molecule of human transferrin (HTF/2N) was studied by proton nuclear magnetic resonance spectroscopy. The pH-dependent titration… Expand
Proposed reference method for iron in serum used to evaluate two automated iron methods.
- A. Valcour, G. Krzymowski, M. Onoroski, G. Bowers, R. Mccomb
- Chemistry, Medicine
- Clinical chemistry
- 1 October 1990
The manual Reference Method of the Centers for Disease Control for serum iron (CDC/RM/Fe) and a semiautomated adaptation of it were used to evaluate two working methods: one, a detergent… Expand
Evaluation of the IFCC reference method for alanine aminotransferase: spurious blank ALT activity due to contamination of D-alanine with L-alanine, and recommendations for a correction.
- A. Okorodudu, P. Pelletier, A. Valcour, G. Bowers, R. Mccomb
- Chemistry, Medicine
- Clinical chemistry
- 1989
During an evaluation of the IFCC reference method for alanine aminotransferase (ALT, EC 2.6.1.2), we noted that the specimen blank activity reaction was markedly increased. Experience with five… Expand
