A Study Of Acoustically Activated Nanodroplets, Songita Choudhury May 2018

A Study Of Acoustically Activated Nanodroplets, Songita Choudhury

Theses & Dissertations

Current treatment of acute myocardial infarction (AMI), which is the main pathophysiological event leading to death in the United States, has advanced considerably with the introduction of emergent percutaneous interventions, but there remains an urgent need for novel techniques to rapidly and accurately detect infarcted or ischemic tissue that results from AMI. Ultrasound contrast agents, also known as microbubbles (MB), have become commonplace in echocardiography. However, MBs are purely intravascular tracers and unable to cross endothelial barriers due to size. The limitations of MBs, namely size and short circulation times within the human body, led to the development of phase-change …


Cardiac Consequences Of Selective Adrenergic Cell Ablation In Mice, Lahari Tumuluri Jan 2016

Cardiac Consequences Of Selective Adrenergic Cell Ablation In Mice, Lahari Tumuluri

Honors Undergraduate Theses

Phenylethanolamine-N-methyltransferase (Pnmt), is the enzyme that catalyzes the conversion of noradrenaline to adrenaline. It has been found in the embryonic heart and in certain adult heart cells, including intrinsic cardiac adrenergic cells, intracardiac neurons, and cardiomyocytes, but their physiological role in the heart is not well understood. To determine the function of Pnmt-expressing cells in the developing heart, a novel genetically-targeted mouse model that causes selective cellular suicide of Pnmt-expressing cells was created by mating Pnmt-Cre Recombinase knock-in mice (PnmtCre/Cre) with ROSA26-eGFP-DTA (R26R+/DTA). The “cellular suicide” allele is the Diptheria Toxin A (DTA) gene …
