A blood test for breast cancer 5 years before signs
A blood test could detect breast cancer up to five years before any clinical signs of the disease, according to researchers.
Cancer cells produce proteins called antigens that trigger the body to make antibodies against them: autoantibodies.
Researchers at the University of Nottingham say they are developing a test that identifies the body's immune response to tumour-associated antigens (TAAs), as they are a good indicator of cancer.
University of Queensland scientists say a blood test could diagnose deadly eye melanoma early, after discovering markers in the blood that can differentiate between a benign mole and a melanoma. With further development, the blood test could be used as a monitoring tool with optometrists, GPs, and specialists and may also be able to identify if the cancer has spread to other areas of the body. |http://bit.ly/2rGJk89
A few years ago Westmead Children’s Hospital in Sydney was looking for a material for 3D printing that simulates bone. The aim was to help surgeons go into a theatre to operate, by giving them more understanding of bones so they can test implants and understand how the material will react when you drill or cut into it. 3D printing has a huge advantage, because you can repeatedly print the bone to the exact size and scale of the child they’re about to do the surgery on. As a result a multidisciplinary team at UNSW Built Environment has developed a bone simulation project with practical application.https://newsroom.unsw.edu.au/news/art-architecture-design/unsw-researcher-using-3d-printing-simulate-
Researchers have found a woman with a rare genetic mutation that has protected her from dementia even though her brain has developed major neurological features of the disease. The woman with an Alzheimer’s-causing mutation and lots of beta-amyloid buildup (red, above) in her brain remained cognitively healthy for decades.This case comes at a time when the Alzheimer’s field needs new approaches after billions of dollars have been spent on developing and testing treatments and many have failed. It has been more than 15 years since the last treatment for dementia was approved, and the few drugs available do not work very well for very long.https://www.sciencemag.org/news/2019/11/colombian-woman-s-genes-offer-new-clues-staving-alzheimer-s
