Advantages And Disadvantages Of Biomaterials

847 Words4 Pages

Biomaterials have played an indispensable role in biomedical applications for centuries. Early designs of these materials primarily focus on matching the mechanical and physiological function of the replaced part without inducing any adverse reaction within the system [1]. With the advancements in the biological and engineering sciences, biomaterials are being utilized in applications which are intended to engineer tissues, intelligent materials, tissue culture, drug delivery systems, artificial organs, and biomimetic systems and materials [1-2]. Biomaterials can be made using natural materials, metals, polymers, ceramics, and composites. Among these materials, the composite biomaterials show the most progressive innovations for biomedical applications as these comprise of at least 2 different kinds of materials, which can either be used as a matrix or filler, with their intrinsic properties remain distinct even after putting them together. In addition, a composite is made of materials which complement the properties of the other by, for example, filling the weakness of the matrix with a selected material for fillers [2]. The skin and mucosal barrier has a natural tendency to produce an antimicrobial barrier to make the inner environment of the body sterile. The microorganisms which threaten the system are enclosed inside this barrier and are not allowed to go out [3]. But, the presence of an injury causes weakening in the antimicrobial barrier, provided by the skin, against

    Inflammation is the main type of innate immunity our body uses against A. schmiddy. Inflammation begins by activating acute-phase proteins, and soon after vasodilation occurs, followed by redness, swelling, pain, and heat. Once vasodilation occurs, histamine and kinins are released and blood vessels permeability is increased, causing white blood cells to report to the infected area. One problem associated with inflammation is that the capsule of A. schmiddy is an important virulence factor, which helps the bacteria to resists phagocytosis. Because the phagocytes cannot destroy the bacteria cells, infection further continues and necrotic tissue forms.

  • Pros And Cons Of Cochlear Implants

    1166 Words  | 5 Pages

    Cochlear implants represent a relatively new approach to treating deaf and partially deaf peoples via surgical implantation of a device which receives sounds from the environment, and transmits them via electrical stimulation of the auditory nerve. The cochlear implant represents an effective way to treat the hearing impaired on a case-by-case basis, offering successful results to those who otherwise may never be able to hear. We must disregard the population who have had both positive and negative reactions to the surgery to understand the surrounding controversy, which does not focus on the efficacy and success of the cochlear implant on the recipient, but rather on the deaf culture and whether the use of such a device imposes a societal standard which marginalizes the hearing impaired and categorizes them as “disabled”.

    Staphylococcus epidermidis is the organism that was identified based on the tests that I had conducted. The tests that I used to identify this organism were the coagulase test and the catalase test. My bacterium was beta hemolytic as well. First, a gram stain had to be done to determine whether the organism was a gram positive organism or a gram negative organism. This determined which set of tests that had to be done.

    The following research was used to predict the antimicrobial effect of Epi-1 in MRSA skin infections in mice. One centimeter of the skin of the ventral region of mice was removed and a lethal dose of MRSA in presence or absence of methicillin, vancomycin or Epi-1. The untreated as well as the methicillin treated mice died in about four days while the one treated with Epi-1 survived. Epi-1 had the following effects: reduced the MRSA count, closure of the wound and increased angiogenesis at the wound area. It also reduced serum level of proinflammatory cytokines TNF-a, IL-6, and MCP-1 as well as regulated the recruitment of monocytes and clearance of lymphocytes around the wounded region during healing.

    “Biophilic design is the deliberate attempt to translate an understanding of biophilia into the design of the built environment” (Kellert, 2008). It involves building and landscape design that enhance human well-being by fostering positive connections between people and natural environment. It is an innovative design approach that aims to maintain, enhance and restore the benefits of experiencing nature in the built environment. It starts by observing the effect of the mutual interaction between the natural and the built environment. The learned knowledge is then reflected onto the design and construction of the built environment.
