1.Simultaneous determination of estrogens (ethinylestradiol and norgestimate) concentrations in human and bovine serum albumin by use of fluorescence spectroscopy and multivariate regression analysis.
Hordge LN1, McDaniel KL1, Jones DD1, Fakayode SO2. Talanta. 2016 May 15;152:401-9. doi: 10.1016/j.talanta.2016.02.034. Epub 2016 Feb 17.
The endocrine disruption property of estrogens necessitates the immediate need for effective monitoring and development of analytical protocols for their analyses in biological and human specimens. This study explores the first combined utility of a steady-state fluorescence spectroscopy and multivariate partial-least-square (PLS) regression analysis for the simultaneous determination of two estrogens (17α-ethinylestradiol (EE) and norgestimate (NOR)) concentrations in bovine serum albumin (BSA) and human serum albumin (HSA) samples. The influence of EE and NOR concentrations and temperature on the emission spectra of EE-HSA EE-BSA, NOR-HSA, and NOR-BSA complexes was also investigated. The binding of EE with HSA and BSA resulted in increase in emission characteristics of HSA and BSA and a significant blue spectra shift. In contrast, the interaction of NOR with HSA and BSA quenched the emission characteristics of HSA and BSA. The observed emission spectral shifts preclude the effective use of traditional univariate regression analysis of fluorescent data for the determination of EE and NOR concentrations in HSA and BSA samples.
2.Hypercoagulability in adolescent girls on oral contraceptives-global coagulation profile and estrogen receptor polymorphisms.
Zia A1, Callaghan MU2, Callaghan JH3, Sawni A4, Bartlett H5, Backos A5, Marshall S5, Chitlur M2, Rajpurkar M2. Am J Hematol. 2015 Aug;90(8):725-31. doi: 10.1002/ajh.24064.
Oral contraceptive (OCP) induced changes on coagulation are complex with high inter-individual variability. The precise reason for differences in this variability is unknown. We hypothesized that global coagulation assays better delineate these changes and variability in hypercoagulability may be the result of differences in estrogen metabolism and thrombophilia. Fifty-two adolescents initiating OCPs were prospectively enrolled; 33 subjects completed the study. Samples were analyzed prior to and after OCPs for procoagulant and anticoagulant factor activities and thrombin generation (TG) +/-thrombomodulin. Participants were genotyped for common thrombophilia and estrogen receptor-α (ESR-α) single nucleotide polymorphisms (SNPs). SNP genotypes were compared to coagulation parameters; TG parameters and differences pre and post OCPs were examined. At baseline, a striking finding was elevated FVIII levels. FVL was absent in all and F2 G20210A was present in one participant.
3.Use of combined oral contraceptives and risk of venous thromboembolism: nested case-control studies using the QResearch and CPRD databases.
Vinogradova Y1, Coupland C2, Hippisley-Cox J2. BMJ. 2015 May 26;350:h2135. doi: 10.1136/bmj.h2135.
OBJECTIVE: To investigate the association between use of combined oral contraceptives and risk of venous thromboembolism, taking the type of progestogen into account.
