Abstract: The present disclosure describes an unexpected and novel insight into hepatic insulin resistance through the description of the ability of VEGF inhibitors to revert hyperglycemia and hyperinsulimenia in murine Type 2 diabetes mellitus models through modulation of a HIF-2?-IRS-2 axis operative in hepatocytes. As such, the data of the present disclosure uncover a novel pathway regulating hepatic IRS-2 expression, and identify VEGF inhibitors as an FDA-approved class of therapeutics capable of increasing liver IRS levels and ameliorating Type 2 diabetes mellitus. Accordingly, this disclosure identifies stabilization of HIF-2? as a robust method for improving glucose metabolism.

Abstract: Ultrasonic imaging to receive a signal from contrast agent microbubbles in arterioles of a myocardium, without being masked by a signal from microbubbles in capillaries of the myocardium. For example, high power ultrasonic energy is emitted to destroy microbubbles in the arterioles and capillaries. A time delay passes from the destruction. The time delay is sufficiently long to allow the arterioles to refill with microbubbles and sufficiently short so that the capillaries do not completely refill with microbubbles. Ultrasonic imaging is then performed to receive a signal between harmonics from the microbubbles refilled in the arterioles. Various other destructive and non-destructive imaging techniques are disclosed.
