Australian Scientists BARRY MARSHALL & FIONA WOOD
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.
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”
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.
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.
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.
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.
