Modeling of Pulsed Thermography in Anisotropic Media

, 1999
As active thermography continues to gain acceptance as an NDE tool for both inservice and manufacturing applications, the need for robust physical models of the process increases. Although the sophistication of both analytical and numerical modeling efforts has increased considerably [1–3], development of a 3-dimensional model for anisotropic media is ...

Ultrasound–triggered tumor‐selective nitric oxide release enhances tumor penetration of antibody–conjugated nanomedicine

Interdisciplinary Medicine, EarlyView.
Ultrasound‐triggered nitric oxide release from S‐nitrosated hyaluronic acid (HA‐SNO) induces tumor vasodilation and disrupts the vascular barrier, potently enhancing the intratumoral penetration of antibody‐conjugated nanomedicines. Abstract The tumor vascular barrier restricts the penetration of antibody‐conjugated nanomedicine, severely limiting its ...
