In Vivo Assessment of Pulmonary Fibrosis and Pulmonary Edema in Rodents Using Ultrasound Multiple Scattering

IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 67(11), 2274–2280.

By: K. Mohanty n, Y. Karbalaeisadegh n, J. Blackwell*, M. Ali*, B. Masuodi*, T. Egan *, M. Muller n 

author keywords: Lung; Ultrasonic imaging; Rats; Scattering; Surgery; Rodents; Acoustics; Multiple scattering; pulmonary fibrosis; quantitative lung ultrasound; random media
MeSH headings : Animals; Disease Models, Animal; Female; Image Interpretation, Computer-Assisted / methods; Lung / diagnostic imaging; Male; Pulmonary Edema / diagnostic imaging; Pulmonary Fibrosis / diagnostic imaging; Rats; Rats, Sprague-Dawley; Ultrasonography / methods
TL;DR: This study verifies the hypothesis that changes in the microarchitecture of the lung parenchyma can be characterized by exploiting multiple scattering of ultrasound waves by the alveolar structure and hypothesizes that in a fibrotic lung, the thickening of theAlveolar wall reduces the amount of air, thereby minimizing the scattering events.

Ultrasound Enhanced Synthetic Platelet Therapy for Augmented Wound Repair

ACS Biomaterials Science & Engineering, 6(5), 3026–3036.

By: S. Nandi n, K. Mohanty n, K. Nellenbach n, M. Erb n, M. Muller n  & A. Brown n 

author keywords: biomimetic; fibrin; wound healing clot retraction; artificial platelet
MeSH headings : Blood Coagulation; Blood Platelets; Clot Retraction; Fibrin; Wound Healing
TL;DR: Application of ultrasound in combination with a subtherapeutic dosage of PLPs resulted in increased clot density and stiffness, improved fibroblast migration in vitro and increased epidermal thickness and angiogenesis in vivo, indicating that this combination therapy has potential to facilitate multiphase pro-healing outcomes.

PHYSICS IN MEDICINE AND BIOLOGY, 64(11).

By: K. Mohanty n, V. Papadopoulou  n, I. Newsome  n, S. Shelton n , P. Dayton n & M. Muller n 

author keywords: multiple scattering; ultrasound imaging; diffusion constant; fibrosarcoma; contrast enhanced ultrasound; microbubbles
MeSH headings : Animals; Disease Models, Animal; Fibrosarcoma / blood supply; Fibrosarcoma / diagnostic imaging; Fibrosarcoma / pathology; Microbubbles; Neovascularization, Pathologic; Rats; Ultrasonography
