Concept explainers
Remember Mr. Ayers, the bus driver from Chapter 18? When we last saw him, he was headed for surgery. Although his dissected aorta was repaired, by the time surgical exposure and blood vessel clamping had been achieved, the dissection had extended up into the origin of his left common carotid artery. As a result, a clot formed that caused a massive stroke. Unfortunately, this left him with severe and permanent brain damage, and he was declared brain dead.
A discussion of Mr. Ayers’s situation with his family confirmed his status as an organ donor. The organ recovery coordinator evaluated Mr. Ayers’s suitability as a candidate for organ donation. Tissue typing (histocompatibility) tests were conducted, and the results were entered into the UNOS (United Network for Organ Sharing) database. Two potential recipients were identified. Mr. Ayers’s right kidney was given in transplantation to a 35-year-old man, and his left kidney was given to a 27-year-old woman. Following surgery, both recipients were placed on immunosuppressive drug therapy.
Why were the recipients of the two kidneys put on immunosuppressive drug therapy?

- (Please answer all parts, thank you!) 1) Mature red blood cells contain hemoglobin for transporting oxygen but contain little else. They lack a nucleus and most organelles. Are red blood cells more or less likely to be infected by a virus? a) More likely b) Less likely 2) How does SARS-COV-2 genetic material get replicated? a) Host cell DNA polymerase b) Host cell RNA polymerase c) RNA polymerase encoded for by viral genome and built in the host cell d) RNA polymerase encoded for by viral genome and originated from the virus 3) How does SARS-COV-2 proteins get built? a) The host cell's ribosome b) Ribosome encoded for by viral genome and built in host cellarrow_forwardWhat is Tumor necrosis factor-alpha (TNF-a)?arrow_forwardA vaccine IMAGINERIX was introduced against a new Gloomy virus (hypothetical names). While the vaccinated population were immunized against Gloomy virus, a few reports followed, claiming that some developed symptoms of multiple sclerosis.

- A friend was recently diagnosed with strep throat. One week after his treatment, he redeveloped the infection. In conversation, your friend tells you, “I must have become immune to the drug the doctor gave me!” a. Discuss the validity of your friend’s statement, providing evidence in support of or refuting his claim. b. After further conversation, your friend tells you that he stopped taking his initial antibiotics after 2 days because he “felt 100% better.” Explain how this action might have played a role in the redevelopment of his infection. c. When he returned to his physician, she ordered a test to determine which antibiotic should be prescribed to treat his reinfection. Summarize a test that could be used to obtain this information.arrow_forwardWhich of the following does NOT result from the malignant proliferation of plasma cells? Question 10 options: A) Lytic bone lesions B) Pancytopenia C) Normal blood volume D) Production of abnormal immunoglobulinsarrow_forwardOne of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells. These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain and other severe complications. If your patient's parents decide to have another child, what is the chance that that child will also have sickle cell anemia? 0% 25% 50% 75% 100%arrow_forward
