Analysis of exogenous dehydroepiandrosterone excretion in urine by gas chromatography/combustion/isotope ratio mass spectrometry.
A detailed procedure for the analysis of exogenous dehydroepiandrosterone (DHEA) in urine by gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS) has been established for… Expand
Automated headspace solid-phase microextraction and in-matrix derivatization for the determination of amphetamine-related drugs in human urine by gas chromatography-mass spectrometry.
An automated extraction and determination method for the gas chromatography (GC)-mass spectrometry (MS) analysis of amphetamine-related drugs in human urine is developed using headspace solid-phase… Expand
Sub-50-nm physical gate length CMOS technology and beyond using steep halo
Sub-50-nm CMOS devices are investigated using steep halo and shallow source/drain extensions. By using a high-ramp-rate spike annealing (HRR-SA) process and high-dose halo, 45-nm CMOS devices are… Expand
Doping with naturally occurring steroids
AbstractThe current definition of doping involves the restriction of the use of naturally occurring compounds The typical examples of such dope agents are testosterone and the related steroid… Expand
Structure-based comprehensive identification of erythropoiesis-stimulating agents and their biosimilars
Erythropoietin (EPO) is a glycoprotein that stimulates production of red blood cells. After the patents for recombinant EPO (epoetin) expired in 2007, biosimilar erythropoiesis-stimulating agents… Expand
