Researchers characterize biomechanics of ovarian cells in mice according to their phenotype at early, intermediate, and late-aggressive stages of cancer
Using ovarian surface epithelial cells from mice, researchers from Virginia Tech have released findings from a study that they believe will help in cancer risk assessment, cancer diagnosis, and treatment efficiency in a technical journal:Nanomedicine.
By studying the viscoelastic properties of the ovarian cells of mice, they were able to identify differences between early stages of ovarian cancer and more advanced and aggressive phenotypes.
To understand the root of the problem of these latter diseases, visualizing brain activity is key. But even the best imaging devices available — fMRIs and PET scans — can only give a “coarse” picture of brain activity.
UCLA neuroscientists have now collaborated with physicists to develop a non-invasive, ultra–high-speed microscope that can record in real time the firing of thousands of individual neurons in the brain as they communicate, or miscommunicate, with each other.
“In our view, this is the world’s fastest two-photon excitation microscope for three-dimensional imaging in vivo,” said UCLA physics professor Katsushi Arisaka, who designed the new optical imaging system with UCLA assistant professor of neurology and neurobiology Dr. Carlos Portera-Cailliau and colleagues.
