Whether myasthenia gravis is an immunodeficiency disease, an autoimmune disease, or an allergic disease. Concept introduction: In immunodeficiency diseases , the response to the antigen by the immune system is ineffective or absent. In autoimmune disease , the immune system of the body will generate a response against particular molecules that are produced by the same host. In allergic diseases , the IgE molecules that are attached on the mast cell are cross-linked by the allergen and causes hypersensitivity reactions.

Select a diet and give a summary of the main components. Do a web search of the diet and choose one link that provides misinformation. Explain why the site itself and/or the information on the site is not credible. This should be a report. This site should be different from U.S News and World Report. For full credit, you must include the following information and elaborate in detail: The diet name The main components of the diet The misinformation website and link What misinformation is being provided in the other website and how did you determine it was not credible?

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data (c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e) absolute po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
