Advances in electron microscopy reveal secrets of HIV and other viruses

The envelope (or Env) protein of HIV is a key target for vaccine makers: it is a key component in RV144, an experimental vaccine that is so far the only candidate to show promise in clinical trials. Also called gp120, the Env protein associates with another protein called gp41 and three gp120/gp41 units associate to form the final trimeric structure. The gp120 trimer is the machine that allows HIV to enter and attack host cells. …

Prostate cancer: Pioneering new imaging method — ScienceDaily

Severely ill prostate cancer patients are helping researchers test a diagnostic tool that involves injecting a radioactive substance into their bodies. Norway has the fifth highest mortality rate for prostate cancer in Europe. Four doses of a radioactive tracer called 18F- FACBC are on their way from Oslo to Trondheim in a private jet. Three NTNU researchers, one doctor, two radiographers and a bioengineer fidget nervously as they wait…

Researchers turn to machines to identify breast cancer type

Since each cell in the body contains 23,000 genes, identifying the specific genes involved in cancer growth is an exceedingly complex task. Researchers used a form of artificial intelligence called machine learning to identify three genes that allowed them to determine whether a tumour was fed by estrogen. "People can’t possibly sort through all this information and find the important patterns," said senior author Russ Greiner, a professor in the Department of Computing Science and investigator with the Alberta Innovates Centre for Machine Learning. …

Machines learn to detect breast cancer

Duo Zhou, a biostatistician at pharmaceutical company Pfizer in New York and colleagues Dinesh Mital and Shankar Srinivasan of the University of Medicine and Dentistry of New Jersey, point out that data pattern recognition is widely used in machine-learning applications in science. Computer algorithms trained on historical data can be used to analyze current information and detect patterns and then predict possible future patterns. However, this powerful knowledge discovery technology is little used in medicine…
