  • Bcg Research Paper

    BCG makes initial contact with tumor cells by means of a fibronectin attachment protein, followed by internalization of the BCG in the cells directing a cell-mediated immunologic response. It has been found in recent studies to be a predominantly T-helper/inducer cell-mediated response with persistence of inflammatory cytokines (Th1-type) for a long time within the BCG- induced granulomas, which maybe be key factor in the recurrence-free state of the patient. The prolonged inflammation results in a continuous level of activating cytokines such as the Interleukin-2, Interferon-gamma and Interleukin-12. In laboratory, the two cellular cytotoxic effector mechanisms that have been determined are the commonly implicated leukocyte-activated killer (LAK) cell cytotoxicity and a newly distinguished cytotoxic phenomenon known as the ‘BCG-activated killer (BAK) cell phenomenon.’ The involved effector cells are the activated natural killer cells (NK cells), in which selectively kill malignant targets (Kapoor, R., Vijjan, V. & Singh, P. (2008))”. Research has also proven that the BCG not only has a local immune activation but “…some degree of a systemic response as well, determined by the multiple cytokines that may be…

Conducting research furthered my curiosity in medicine; I greatly enjoyed reading…

  • Effects Of Bereavement

    (2012) examined a study in which bereaved participants, with a high amount of grief, had more reduced immune responsiveness than individuals with significantly lower grief levels. In this assessment, it was reported that during the initial weeks of bereavement the participants had increased circulation of neutrophils and macrophages, but no changes to lymphocyte and natural killer cells (Buckley et al., 2012). Furthermore, subsequent assessments reported that in the following months,…

  • Execution Day: A Review Of A Film

    EXECUTION DAY presents as a dramatic crime thriller. The story centers on a detective who tracks down a serial killer. Because there have been so many of these types of films, to stand out the script needs to offer the genre something new.
