Ultrasound Stimulation of Insulin Release from Pancreatic Beta Cells
Type 2 diabetes mellitus is a complex metabolic disease that has reached epidemic proportions. Pharmacological management routinely requires complex therapy with multiple medications, and loses its effectiveness over time. Thus, new modes of therapy are needed that will target directly the underlying causes of abnormal glucose metabolism. The objective of our study, funded by NIH, is to explore a novel, non-pharmacological approach that utilizes the application of ultrasound energy to safely augment insulin release from pancreatic beta cells as a potential novel treatment for type 2 diabetes.

Ultrasound-enhanced Ocular Drug Delivery
Our objective has been to determine ultrasound parameters that can provide optimal delivery of different drugs into the eye, study mechanisms of ultrasound action, and determine long-term safety of this application. We showed previously that exposing cornea to therapeutic ultrasound can lead to up to 10 times more delivery of a drug-mimicking compound into the eye, with only minimal alterations in the corneal structure. Subsequently, we continued to work on drug delivery problems with significant clinical relevance, such as promoting delivery of antibiotics and steroids for treatment of eye inflammations. This work is expected to eventually lead to development of an inexpensive, quick and non-invasive ultrasound method that can be applied in an outpatient clinic to allow targeted delivery of medications into diseased eye tissues for treatment of different diseases including infections and retinopathies.
