Gabby's Australian scientists HSC

  1. 1. Australian Scientists BARRY MARSHALL & FIONA WOOD
  2. 2. Barry Marshall Outline the areas in which they are currently working: Barry Marshall is what is known as a gastroenterologist, which is a focus on diseases in the gastrointestinal tract. Marshall is known for his work on Helicobacter pylori infections and treatments, and received his Nobel Prize in 2005 for proving that H. pylori infections caused peptic ulcers. Marshall’s current work is taking Helicobacter and removing the harmful toxins in order to make a vaccine. His focus is particularly on a vaccine for influenza.
  3. 3. Barry Marshall Information about their research: Marshall’s current work is about applying his knowledge to clone a vaccine for influenza. He is removing the harmful toxins from the Helicobacter and trying to make the Helicobacter so that it only lasts in your system for a few weeks. He is combining the Helicobacter with the influenza vaccine in it and in turn this can be digested as a liquid. Marshall’s aim is for a temporary infection to occur so that the immune system fights against the Helicobacter. His idea is “two weeks after drinking something you’d have had a vaccination against influenza”
  4. 4. Barry Marshall How does their work impact society and/or the environment: Barry Marshall’s work has definitely impacted on society. Marshall has discovered that peptic ulcers are caused by a particular bacteria called H. pylori and has also continued his study of Helicobacter pylori infections and treatments. This has impacted positively on society because Marshall has identified the bacteria which causes gastric cancer and ulcers and discovered that the cure for this was antibiotics. 80% of people with Helicobacter have no symptoms, so many people do not know that they are infected. Marshall is working towards putting the influenza vaccine in the supermarket. He wants the vaccine to be placed in foods such as yoghurt, where it is readily available to all people. This enables everyone to have access to this vaccine, and reduces the reliance people have in doctors.
  5. 5. Fiona Wood Outline the areas in which they are currently working: Fiona Wood is a plastic surgeon. She has influenced different methods for treating burns. Fiona Wood is also the co-founder of Clinical Cell Culture which is a company which is recognised for it’s breakthrough research involving how burns are treated.
  6. 6. Fiona Wood Information about their research: Wood has researched ways in which to reduce the scarring caused by burns as she discovered that scarring is greatly reduced if replacement skin was provided within ten days. She is also focusing on treating nerves, the blood supply and the skin, when dealing with burns. Wood is also looking at the origin of the cells come that assist in the healing of the wound. She has helped discover that there is not only inflammatory cells in the wound, but mesenchymal cells which come from bone marrow. Fiona Wood’s most influential work is launching Cellspray which is a spray-on solution of skin cells.
  7. 7. Fiona Wood How does their work impact society and/or the environment: Fiona Wood has impacted greatly on society. She has discovered new ways in which to treat burns and minimise scar tissue. This has changed the way in which burn victims recover and how to stop infections from occurring. Fiona Wood has also researched more about the cells involved in burns, which enable her to treat burns as effectively as she can. An example of when Wood’s work has impacted society was during the Bali bombings where she helped treat 28 Bali bombing victims with injuries including, burns to 2-92% of their body, shock and infections.
