BLOOD BANK HELP: PLEASE READ SCENARIO AND EXPLAIN THOROUGHLY. 7. A patient has a positive antibody screen and you have identified Anti Jka. However, according to the records in your computer system, the patient’s previous antibody screen 9 days earlier was negative. How could this occur and why? Would you do additional testing and if so what testing would you do?

Review Figure 1-8, "Antibody Panel, Case 1-6." In this case study, antibodies are excluded only if the patient's serum does not react with panel cells that are homozygous for the antigen.

PROCEDURE 1 Time to Trace! In this procedure, you will be tracing two invaders: bacteria in the extracellular fluid and a virus that has infected cells. To keep things simple, you will trace the main pathway and the main immune response to the pathogen. Do note, however, that the actual response is much more complex, and your instructor may wish you to include more information. You are provided with hints and the number of steps you should aim to include for each organism, but you will likely want to consult your textbook for more help. After you have completed the activity, answer Check Your Understanding Questions 5 and 6 (p. 586). Start: bacteria in the extracellular fluid → bacteria damage local macrophages and damaged macrophages release that attract to the area → these cells phagocytize and bacteria and secrete chemicals to attract granulocytes called at the same time, cells called cells ingest bacteria and migrate to these cells present antigens to TĦ cells → TH cells activate…

This is homework not a test! From NTSA case study https://static.nsta.org/case_study_docs/case_studies/cystic_fibrosis.pdf Please help with questions 2, 3 and 4 of part four 2. "The successful use of gene therapy to cure SCID syndrome (2000) is hoped to be a permanent cure for those patients because a good copy of the problem gene was inserted into the patients' blood stem cells in the bone marrow (hematopoietic stem cells). Once white blood cells enter the blood stream they have a limited life span, on the order of a few week to months. The blood stem cells are the cells that create more white blood cells to replace those that are lost. If the gene was only inserted into the circulating mature white blood cells, the patient would only be temporarily cured until those cells were used up or died." The current gene therapy approaches to cure CF involve inserting a functional CFTR gene into the mature epithelial cells of the lungs. In light of the preceding paragraph, do you think that…
