  • Analysis Of Robert S. Desowitz's The Malaria Capers

    emerging much faster than the scientific community as a whole could understand and accept them. Desowitz then goes into the frustration the people were dealing with Kala azar. The first problem was how the disease even migrated or spread over continents and eventually to the Indian continent. The health officials were unfamiliar with this disease, often mistaking it with malaria. With no vaccine and no idea of any control mechanisms, it took many infected patients and a few years for them to determine that it was infact Kala azar and not malaria. Ending the first section of the book, Desowitz tells us that Leishmania donovani, the vector for the Kala azar disease, could have possibly killed of the dinosaurs. Studies have shown that Leishmania donovani, carried by the sand fly, dates back to historical flies. If a dinosaur was to be bitten by a sand fly carrying the parasite Leishmania donovani, they could have possibly died from Kala azar…

  • Antagonists: The Classification Of Antagonists

    antagonist. Thus it can be seen that the binding site of competitive antagonists is reversible. Golan et al. (2012) indicated that the existence of competitive antagonists moves the dose-response curve of agonist to the rightward. From this curve, competitive antagonists drop the potency of agonist but still remain the efficacy. The fact is an opioid receptor antagonist, it has no intrinsic activity, but competitively antagonizes various opioid receptors. It has a strong affinity, especially for…

  • Apoptosis Research Paper

    It is also evident that the morphological components of apoptosis has been conserved throughout the evolution of apoptosis by genetic control. Despite this, many discoveries have found some indistinguishable PCD features between mammalian cells and unicellular cells. More specifically, the unicellular eukaryote L. major clearly expresses many features that can also be inspected in mammalian cells. Leishmania major is a protozoan parasite from an ancient phylogenetic branch of unicellular…

  • Benzimidazole Derivatives Lab Report

    hydrolase or IPCase activity) and sphingomyelin (the SMase activity). SMase activity is required for amastigote proliferation in mammals while the IPCase activity is important for promastigote survival and acid tolerance. Deletion of ISCL leads to a complete loss of SMase and IPCase activity. (Figure 1a) In order to derive a system’s level understanding of the role of ISCL in the sphingolipid metabolism, we reconstructed the entire sphingolipid metabolism of L.major. (Figure 1b) Simulation…

  • The Importance Of Social Behavior Among Monkeys

    the leaf. Anti-parasite activity due to chemicals produced by these plants (whole leaf swallowing) was ruled out. Short hairs located on the leaves appear to be responsible for the eviction of the parasites. Chimpanzees select these plant species for their physical, roughness properties, resulting in the physical purging action of adult parasites by the leaves. Thus whole leaf swallowing is one self-medication strategy used by chimpanzees against gastrointestinal parasites. Bitter leaf-chewing…
