Determination by liquid chromatography–mass spectrometry of clomiphene isomers in the plasma of patients undergoing treatment for the induction of ovulation

Efficacy and safety of a popular thermogenic drink after 28 days of ingestion

“…Assay precision [i.e., coefficient of variation (C V )] and accuracy (i.e., percent of unrecovery which is the percentage deviation from 100%) were calculated using glycerol and FFA control samples by 8 replicate determinations per analyte. In the current investigation, the C V and percent of unrecovery using a 240 μM glycerol and 0.35 mM free-fatty acid control serum was 2.5% and 1.2%, as well as 8.9% and 3.6%, respectively, which is in accordance with previously accepted guidelines [ 11 , 12 ].…”

Acute effects of ingesting a commercial thermogenic drink on changes in energy expenditure and markers of lipolysis

“…Assay precision (coefficient of variation (C V )) and accuracy (percent of un-recovery) were calculated using control samples for glycerol and FFAs by 8 replicate determinations. The reported C V and percent of un-recovery for glycerol (240 μM control serum: 2.5%, 1.2%) and free fatty acid control serums (0.35 mM control serum: 8.9%, 3.6%) were found to be within acceptable ranges [ 22 , 23 ].…”

Evaluation of the relationship between plasma concentrations of en- and zuclomiphene and induction of ovulation in anovulatory women being treated with clomiphene citrate

“…Serum concentration of Zu and En were measured by liquid chromatography-mass spectrometry, as described by Crewe et al (25). The limits of determination were 35 pg/mL and 7 pg/mL for Zu and En, respectively.…”
