Highly active antiretroviral therapy (HAART) is the most effective prophylaxis and treatment in patients with acquired immunodeficiency syndrome (AIDS) with which type of infection?
a. Cyclospora
b. Sarcocystis
c. Cryptosporidium
d. Toxoplasma
C
In industrialized nations, the most effective prophylaxis and treatment for cryptosporidiosis in patients with AIDS is the use of HAART. The eradication and prevention of the infection are related to the replenishment of CD4+ cells in treated persons and the antiparasitic activities of the protease inhibitors used in HAART. A relapse of cryptosporidiosis is common in patients with AIDS who have stopped using HAART.

Imagine that you are investigating the production of insulin in normal cells to help determine the cause of faulty insulin production in cells where insulin appears to be synthesized but fails to be secreted from the cell
You design experiments using three different pharmaceutical compounds to help pinpoint the trouble spot in the protein synthetic pathway. The first compound blocks transport vesicle movement in the cytoplasm. The second blocks the SRP release from the ribosome and mRNA. The third compound binds to and blocks the signal sequence so the SRP cannot recognize it. For each of these three treatments, indicate 1) whether the protein would be made at all, and if so, 2) where in the cell you would find it. What will be an ideal response?
