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…

- PREGNANCY TEST Principle: The Advanced Quality Pregnancy Test is a sandwich immunoassay. The plastic card supports a membrane which has been coated with reagents necessary to detect the presence of hCG and provide a positive control so the user can determine if the test result is valid. The sample is applied to the card and reacts initially with the specific, anti – bhCG monoclonal antibody / colloidal gold conjugate on the test membrane. This mixture moves along the membrane, by capillary action, and reacts with a specific anti – hCG in the test region. If hCG is present in the sample, the result is the formation of a colored band in the test region. If there is no hCG in the sample, the area will remain white. The sample continues to flow to the control region and forms a pink to purple color, indicating the test is working and the result is valid. Questions 1. What is hCG? Why is it used to check for pregnancy? 2. Is it a cause for concern if a male patient shows…Question 1 Nursing. Innate lymphoid cells reside primarily in tissues such as the lungs, the lining of the gastrointestinal tract, and the skin, because these sites represent the major routes of entry of pathogens into the body. Several different subsets of innate lymphoid cells exist, and each is specialized to respond to a category of pathogen (e.g., viruses, extracellular bacteria, helminthic parasites, etc). a) True b) FalseANTI - STREPTOLYSIN O TITER ASO Latex Test ASO is a rapid latex agglutination test for the detection of anti – streptolysin O (ASO) antibodies in human serum. ASO antibodies are found in sera of patients in response to infection with hemolytic streptococci of group A, C or G. Streptolysin O is highly antigenic therefore patients with these infections produce specific antibodies detectable by the reagent. Questions: 1. Illustrate how latex agglutination works to bind to ASO and form agglutinates 2. What is the significance of ASO? Is ASO specific to a disease? 3. What are Todd Units? Give the normal value of ASO
