  • Systemic Lupus Erythematosus Case Study

    The humoral immune system is responsible for making response to the pathogens which invade our body. However, an abnormal immune system induces Cytotoxic T‐cells secrete toxic substances, for example, hydrogen peroxide in the body cells and kill the body tissues. This is called the autoimmune disease. One example of autoimmune diseases is systemic lupus erythematosus, which nearly 5 millions people are suffering various kinds of symptoms of this disease around the world (Centers for Disease…

  • Advantages And Disadvantages Of Tri-O-Acetyloride

    (for example, adenine and cytosine) can form N-oxides. Also, the C8 position of guanosine is vulnerable to hydrolytic attack under either strongly acidic or strongly alkaline conditions. The 5,6 double bond of pyrimidine nucleosides also reacts with halogens and halohydrins to give the corresponding addition products (Shabarova and Bogdanov, 1994). Selected examples of the side reactions that occur during oligonucleotide synthesis are given below. Tri-O-acetyluridine (S.1) reacts with MSNT to…

  • Relationship Between Fluoride And Oral Health

    This paper explores multiple published articles that have reported results from research conducted case studies displaying the relationship between fluoride and oral health when discussing the fluoride concentration within a public water system. These articles, however, are quite similar in their findings, yet differ in the location the study was conducted in and age groups that were focused on. This paper examines Banóczy (2013), Peterson (2015), as well as O’Sullivan & O’Connell’s (2015)…

  • Disadvantages Of Robotic Surgery

    Because incisions were made smaller, this robot-dependent surgery was known to be less invasive than preceding surgical methods. Because their was less intrusion in the body, the risk of infection was reduced, hospital stays were shorter, and recuperation time was reduced.(Vertut and Coiffet 97)Since this implementation of Robots as an assistant in delicate operations, numerous procedures have been performed laparascopically as both technology and skills of surgeons have advanced. Despite the…
