Honors Chemistry p: 5 27 September 2013 Chemical Applications in Real Life Scenarios “Case Study B” Although chemicals generally have the same appearance in a liquid solution‚ they vary extremely from the fact that some may have no effect and others can cause death. One of the few ways that a certain chemical solution can be identified is through a simple test called a flame test. A flame test works by placing a certain chemical solution in an open flame and noting the color the flame changes

DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to

Daclizumab (Biogen Idec and Abbott Biotherapeutics Corp.) is a humanized mAb acting as a blocker of the α-subunit (CD25) of the high-affinity IL-2 receptor [19]. IL-2 is secreted by activated lymphocytes and stimulates production of other proinflammatory cytokines while it is also involved in lymphocytic proliferation. Daclizumab was initially approved for the prevention of renal allograft rejection as part of a combination regimen and evidence was progressively accumulated showing that this drug
