Magnetic particles-based chemiluminescence immunoassay for progesterone determination

© 2017, Chiang Mai University. All rights reserved. A magnetic particles-based chemiluminescence immunoassay was investigated for progesterone detection by using luminometer. In this work, progesterone was determined based on the competitive binding between progesterone in the sample and progesterone-horseradish peroxidase (HRP) conjugate for a constant amount of rabbit anti-progesterone. Initially, anti-rabbit IgG coated magnetic particles conjugated with primary progesterone antibody were bound to progesterone in the samples. Then, the amount of proge sterone was quantified by reacting with the residual unoccupied antibody sites with HRP-progesterone, followed by HRP substrate (luminol, H 2 O 2 , and p-iodophenol (PIP)) and finally detection of the generated chemiluminescence by a luminometer. The intensity of the emitting light was proportional to the amount of enzyme present (HRP-progesterone) and was inversely related to the amount of unlabeled progesterone in the sample. The optimum conditions for determination of progesterone were obtained at 0.15 μg L -1 magnetic particles, 5.0x10-4 mol L -1 luminol, 5.0 × 10 -3 mol L -1 H 2 O 2 , 1.0 × 10 -3 mol L -1 PIP, and phosphate buffer saline buffer pH 9. The optimal dilutions of both anti-progesterone antibody and HRP-progesterone conjugate were 1:1000. The linear relationship between chemiluminescence intensity (RLU) and various concentrations of progesterone was over the concentration range of 0.5-50.0 μg L -1 . This proposed method had been successfully applied to the evaluation of progesterone in human sera

Educational level as a cause of type 2 diabetes mellitus: Caution from triangulation of observational and genetic evidence

Background and objective: Education might be causal to type 2 diabetes mellitus (T2DM). We triangulated cohort and genetic evidence to consolidate the causality between education and T2DM. / Methods: We obtained observational evidence from the English Longitudinal Study of Ageing (ELSA). Self-reporting educational attainment was categorised as high (post-secondary and higher), middle (secondary), and low (below secondary or no academic qualifications) in 6,786 community-dwelling individuals aged ≥ 50 years without diabetes at ELSA wave 2, who were followed until wave 8 for the first diabetes diagnosis. Additionally, we performed two-sample Mendelian randomisation (MR) using an inverse-variance weighted (IVW), MR-Egger, weighted median (WM), and weighted mode-based estimate (WMBE) method. Steiger filtering was further applied to exclude single-nucleotide polymorphisms (SNPs) that were correlated with an outcome (T2DM) stronger than exposure (education attainment). / Results: We observed 598 new diabetes cases after 10.4 years of follow-up. The adjusted hazard ratios (95% CI) of T2DM were 1.20 (0.97–1.49) and 1.58 (1.28–1.96) in the middle- and low-education groups, respectively, compared to the high-education group. Low education was also associated with increased glycated haemoglobin levels. Psychosocial resources, occupation, and health behaviours fully explained these inverse associations. In the MR analysis of 210 SNPs (R2 = 0.0161), the odds ratio of having T2DM per standard deviation-decreasing years (4.2 years) of schooling was 1.33 (1.01–1.75; IVW), 1.23 (0.37–4.17; MR-Egger), 1.56 (1.09–2.27; WM), and 2.94 (0.98–9.09; WMBE). However, applying Steiger filtering attenuated most MR results towards the null. / Conclusions: Our inconsistent findings between cohort and genetic evidence did not support the causality between education and T2DM
