Imagine being able to quickly detect and diagnose blood vessel growth in cancerous tumors, and even predict how fast the tumors might metastasize or spread. Researchers at the University of Virginia Health System are doing just that in animal models using millions of tiny microbubbles injected into the bloodstream, coupled with contrast-enhanced ultrasound, an inexpensive and widely-used technique using sound waves to "see" inside the body.
Their findings are published in the July 22 edition of the journal Circulation.
"For the first time, this research shows that scientists can detect cancer using ultrasound contrast agents targeted to abnormal blood vessels that reside within tumors," said Dr. Jonathan Lindner, a U.Va. cardiologist and primary author of the study. "By assessing how much new blood vessel growth there is, we can detect tumors and metastatic spread at a very early stage."

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
