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…
chamber (Stemcell Technologies, Canada) that was gassed with anoxic gas mixture of 5% CO2 and 95% N2 for 5 min [Zeng et al. 2012]. Control cell cultures were maintained in a normal oxygenated DMEM containing 25 mM glucose. After various time intervals, cell cultures were placed back to the normoxic condition with normal culture medium. For concurrent treatment, human APC (Haematologic Technologies Inc, USA) was present in the culture medium during OGD and reoxygenation; for control, only vehicle…
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…
discussion with the class. Ask if any students have ideas why the earths outer layer is constantly changing. Lesson: (20 minutes) This lesson will teach the student about fault lines and boundaries where two separate tectonic plates meet, and why volcanoes are formed. Begin with a brief introduction of the theory of plate tectonics. Explain to the class that plate…
The gas generation is due to E. coli metabolic processes that generates acid and changing the turbidity. 2. The Membrane Filtration Method did work as well. MF method can replace the MNP test for microbiological analysis of water sample. After the incubation of the mEndo plate for 24 hours it is perceptible the grown of E. coli colonies across the plate. The results of this method are shown in the figure 4. As it was used mEndo, just the E. coli colonies form bright green colonies with a…
The region is tectonically characterized by the ~6 kilometer thick oceanic Nazca plate subducting underneath the continental South American plate at a convergence azimuth of ~ 78 ͦ and at a rate of 6.6 centimeters per year making the area one of the most active convergent margins on earth, typically experiencing a Mw > 8 earthquake every 10 – 20 years (Moscoso, et.al., 2011). Notable quakes in recent history include the 1960 Mw = 9.5 Valdivia earthquake which was the largest ever recorded,…
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…
Mt. Pinatubo, Philippines: Impacts and Human Actions The stratovolcano Mount Pinatubo began showing signs of erupting on the 15th of July 1991. Through a series of events Mt. Pinatubo erupted and effected the surrounding areas. Throughout this paper will be discussed the impacts, including primary and secondary, along with impacts changed by humans. Mount Pinatubo eruption was the second largest eruption in the 20th century, making it have many impacts not only locally but globally. Mount…
This paper examples the formation of the Deccan traps, the Deccan continental flood basalt, and present day Indian. Its first provides a brief background on what the Deccan Traps are and the history of their geologic integrity. The proof is explained through scientists seismic tomographic models and the evolution of the Indian plate, the Reunion island hotspot, and the evolution of lithospheric mantle structure. Keywords: deccan, mantle, plate, hotspot, reunion, reconstructions.…
