Pharmacokinetics of acetaminophen-protein adducts in adults with acetaminophen overdose and acute liver failure

LP James, L Letzig, PM Simpson, E Capparelli… - Drug Metabolism and …, 2009 - ASPET
Acetaminophen (APAP)-induced liver toxicity occurs with formation of APAP-protein adducts.
These adducts are formed by hepatic metabolism of APAP to N-acetyl-p-benzoquinone …

Serum sickness–like reactions to cefaclor: Role of hepatic metabolism and individual susceptibility

…, JG Wheeler, SH Childress, LG Letzig - The Journal of pediatrics, 1994 - Elsevier
In an effort to explain the increased incidence of serum sickness-like reactions (SSLR) in

Acetaminophen-induced hepatotoxicity and protein nitration in neuronal nitric-oxide synthase knockout mice

R Agarwal, L Hennings, TM Rafferty, LG Letzig… - … of Pharmacology and …, 2012 - ASPET
In overdose acetaminophen (APAP) is hepatotoxic. Toxicity occurs by metabolism to N-acetyl-p-benzoquinone
imine, which depletes GSH and covalently binds to proteins followed by …

Targeted liquid chromatography–mass spectrometry analysis of serum acylcarnitines in acetaminophen toxicity in children

…, L Pence, PM Simpson, P Gill, LG Letzig… - Biomarkers in …, 2014 - Future Medicine
Aim: Long-chain acylcarnitines have been postulated to be sensitive biomarkers of

Validation of a liquid chromatographic method for the determination of ibuprofen in human plasma

H Farrar, L Letzig, M Gill - Journal of Chromatography B, 2002 - Elsevier
A simple, rapid method of determining the ibuprofen concentration in small volumes of human
plasma (50 μl) by HPLC was developed. The sample was prepared for injection using a …

[HTML][HTML] MicroRNA regulation of CYP 1A2, CYP3A4 and CYP2E1 expression in acetaminophen toxicity
