On May 11th, 1978, a young white couple was abducted in the Homewood neighborhood in Chicago (4). The next day their bodies were found in an abandoned house in East Chicago Heights, which is now known as Ford Heights. Both of them had been shot, and the young woman, Carol Schmal, had been gang raped. The male victim’s name was Lawrence Lionberg. Following a tip, which later turned out to be false, two men were arrested for the crime. The main witness to the crime was a young woman named Paula…

was performed in multiple locations of each quadrant in the hemocytometer calculate the percent of cells that were dead after one-hour treatment with carbaryl. There were a total of sixteen trials of cell counts for each treatment. Cell Viability Assay on…

The homogenate was centrifuged at 16,000 rpm for 15 min at 4°C (Karthikeyan et al., 2005). The supernatant served as source of enzyme for peroxidase assay. The reaction mixture consisted of 2.1 ml distilled water, 0.32 ml 100 mM potassium phosphate buffer (pH 6), 0.32 ml 5% freshly prepared pyrogallol solution, and 0.16 ml 0.5 % H2O2. Reaction mixture was mixed properly and incubated at room temperature…

postnuclear supernatant fluid is centrifuged at 2200rpm for 30 minutes and a temperature range from zero to four degrees Celsius to acquire the mitochondrial pellet. The postmitochondrial supernatant fluid is discarded, and seven milliliters of mannitol assay medium at room temperature is added to the pellet. The pellet is scraped and mixed with the mannitol to disperse the mitochondrial fraction evenly. Afterwards, the mitochondrial suspension was immediately put on ice to prevent any enzyme…

Chapter 4 - Discussion A standard curve of p-nitrophenol was drawn at the start of the project, before any enzyme assay of the fractions. The standard curve is set up so the equation of the line can be used to measure the enzyme activity in each sample fraction. P-nitrophenol shows a linear relationship with acid phosphatase. An Enzyme assay gives the activity levels of acid phosphatase in each fraction. The results from each fraction were placed into the equation of the line from the standard…

Water and ethanol extract exhibited 99.1% and 77.5% inhibition of peroxidation in linolinic system at 100µg quantity. All assays for antioxidant are effective in water and ethanol. The property of antioxidant is increasing when concentration and amount of sample increased. Finally this study concluded that the fennel seed show s the excellent in vitro antioxidant property though…

Mixed contamination of PAHs and metals occur ubiquitously in the environment, but their combined toxicity to humans and other organisms are not fully addressed. The data from epidemiological, animal and in vitro studies indicated the nature of interaction between PAHs and metals varies from synergism to additivity or antagonism. In this chapter, the combined toxicity of PAHs and metals on toxicokinetic and toxicodynamic endpoints, and possible mechanism of actions were discussed. In addition,…

Product description for 1 oz. Royal Canadian Mint Gold Bar The utility of gold bars as an investment option that diversifies your portfolio, is both widely known and recognized. These one-ounce ingots are fashioned by the esteemed Royal Canadian Mint, known for their products’ quality feel and finish as well as their beautiful designs. The Royal Canadian Mint was set up in 1908, although it was known as the Ottawa Mint at the time, which originally started as the Canadian branch of the British…

Approach: The specific aim of this Phase I project is to establish the technical merit and feasibility of detection of HCV RNA using an innovative assay called TARA. The overall work principles and design of the assays are shown in Figure 1. We will use peptide nucleic acid (PNA)-based probes to investigate in detail the signaling power and the selectivity of a transfer reaction (Figure 2). PNA is a chemically and biologically stable DNA analogue that combines an increased affinity towards DNA…

The results were compared with that of free PTX by MTS assay using CellTiter 96 Aqueous One Solution Cell Proliferation Assay Kit (Promega of USA). All cells were plated overnight in 96 well plates with a density of 5,000 cells per well in 100 µL appropriate growth media overnight in a 96 well plate. The cytotoxic drugs (Paclitaxel, ACIN…
