    The assay was performed as described in section 3.2.2.2. P4 concentrations were analysed in spent culture media for cells cultured for 48, 96 and 144 hr in the present of melatonin 0, 20, 200 and 2000 pg/ml under both 5% O2 and air condition. Samples were diluted 100 fold in PBS and analysed in duplicate with standard (0, 0.5, 1, 2, 5, 10 and 20ng/ml), blank and quality control. To avoid variation among plates, all samples were run together. Inter and intra assay % CV was (11.1) and (5.1) respectively. 4.2.3.2 Oestradiol…

    However, according to this paper, some of the limitations of ELISA based testing are the hourly delay; the time in which antigen binds to the coated antibodies. The excessive use of reagents to coat and wash the 96-well plate, and the 96-well plates it is self where the assay is performed on. Therefore, this article introduces 3D printing platforms for ELISA 96-well plates. With 3D plates, sensitivity of the assay increased as well as antibody binding time to the 96-well plates bay 2 to 3 folds…

    4.2.1. Material: Lead zirconate titanate (PZT) PZT is a short for lead zirconate titanate inorganic compound that has a chemical formula of Pb [ZrxTi1-x] O3 (0 ≤ x ≤ 1). PZT is made and composed of the two chemical elements lead and zirconium combined with the chemical compound titanate while formed under extremely high temperatures. The dielectric constant of PZT can range from 300 to 3850, depending upon orientation and doping. PZT possesses piezoelectric effect meaning that it changes shape…

    a key role in the accuracy of long bone fusion and growth (US Department of Health and Human Services 2004). In many archaeological contexts the odds of finding unfused epiphyseal ends are unlikely as they are very prone to damage or loss. The measurements of the long bones and the charts that correlate the dates of fusion of the primary, secondary and tertiary ossification centers (Schaefer, Black, and Scheuer 2009b) allowed us to narrow down the age of the specimen. By using the numbered…
