Hiv 4

  1. 1. Dr. Fabian’s presentation was based on recent studies associated to HIV withcognitive disorders. First, he mentioned that HIV is a retrovirus that causesimmunodeficiency syndrome. That is a condition in humans in which the immunesystem progressively fails, allows life-threatening opportunities, and can evencause cancer. Secondly, he pointed out that blood, semen, and vaginal fluids,pre-ejaculation, or breast milk could transfer HIV. He referred to the retrovirus asan RNA virus that produces DNA from its RNA genome. The cells infected by theHIV virus are the brain macrophages and microglia. The major organs that theHIV infects are the central nervous system and the gastrointestinal tract. Thirdly,he talked about the sphinogolipids that are a class of lipids whose function is toenrich the central nervous system. The central nervous system plays importantroles in signal transduction. In this study used three types of monkeys andinjected the virus to the monkey to compare it with the HIV in humans.Overall, I would say Fabian did an excellent job in presenting his topic. Hedemonstrated the he new what he was talking about, came well prepared andwas very organized. Also he showed great amount of enthusiasm like the othertwo presenters. They truly lived and felt what they were doing. This is a sign of aperson who is knowledgeable and creates an environment for other people toinquire and develop new ideas.In addition, I would suggest that he also improve his diction because there weretimes that I couldn’t understand what he was saying. Furthermore, his lack ofcommunication skills didn’t allow him to express really well what he was workingon.This field trip was an outstanding experience and I learned a lot from thepresentations and the tours. As the field trips come to an end, I noticed onething. In science there are a lot of fields and a lot of choices so we should notfocus on only one but rather be opened to the many available options.
