S8e10: How Can Nature-Inspired Engineering Improve Human Health?, Ron Lisnet, Caitlin Howell

The Maine Question

Antibiotic resistance has become a growing problem in the treatment of bacterial infections. In addition to minimizing or negating the effects of existing medicine, these antibiotic-resistant bacteria, or “superbugs,” are mutating faster than the development of new remedies.

Caitlin Howell, University of Maine associate professor of biomedical engineering, is working on new tools that take notes from nature to combat antibiotic-resistant bacteria. Similar to the way in which the human body keeps balance with its own bacterial populations, Howell’s devices use nontoxic, non-invasive surface-based technology to trap bacteria and prevent them from spreading.

Computational Analysis And Classification Of Shg Images Of Cancerous Pancreatic Tissue Based On Collagen Fiber Alignment, Gerren Welch

Honors College

Pancreatic cancer is a deadly disease, with a low five-year survival rate partly due to the difficulty in diagnosing the cancer early in its development, as it shares symptoms with more common and less lethal conditions. Using Second Harmonic Generation (SHG) microscopy and computer analysis, our knowledge of the biophysics of the pancreatic tumor microenvironment increases which may lead to the development of more effective therapies. In collaboration with Maine Medical Center Research Institute (MMCRI), we have identified 20 pancreatic cancer patients. In these 20 pancreatic cancer patients, Dr. Jones, a pathologist at MMCRI has identified normal adjacent pancreas, fibrotic …
