J Am Soc Mass Spectrom
. 2005 Aug;
16(10):1631-40.
PMID: 16085421
Accurate mass measurements are often used in the structural determination of unknown compounds of low molecular mass (i.e., below approximately 500 Da). Recently, it has been shown that accurate mass...

. 2005 Mar;
40(4):481-6.
PMID: 15795599
Background: Inborn errors of bile acid synthesis are rare but potentially treatable causes of neonatal cholestasis. We here present a cholestatic infant with an ongoing cytomegalovirus infection who despite intensive...

. 2005 Jan;
39(8):703-22.
PMID: 15638239
Cholesterol and its metabolites, e.g., steroid hormones and bile acids, constitute a class of compounds of great biological importance. Their chemistry, biochemistry, and regulation in the body have been intensely...

10(1):63-88.
PMID: 15100480
Neutral oxosteroids have been derivatised with Girard T and P hydrazine reagents to give the corresponding Girard hydrazone quaternary ammonium salts. Both Girard T (GT) and Girard P (GP) hydrazones...

3(7):692-703.
PMID: 15073272
Nuclear receptors (NRs) constitute a large and highly conserved family of ligand-activated transcription factors that regulate diverse biological processes such as development, metabolism, and reproduction. As such, NRs have become...

75(4):1022-30.
PMID: 12622400
It is well-established that electrochemical reactions can occur within the capillary of an electrospray (ES) devise coupled to a mass spectrometer. In fact, such reactions must occur to maintain charge...
