Dr. Roberto Levi
Dr. Roberto Levi
was born and raised in Italy where he obtained an MD degree and a DSc in
Pharmacology from the University of Florence. He did his Postdoctoral
training in Pharmacology for two years at Johns Hopkins University Medical
School as a Fulbright Scholar. He has spent his entire academic career at
Cornell Medical College as a cardiovascular pharmacologist, concentrating
his activities in research and teaching. The general research theme of the
Levi Lab is the role of endogenous modulators of cardiac adrenergic
function. Among these modulators, Dr. Levi has focused on the
renin-angiotensin system in the heart and on the role of histamine in
cardiac function and dysfunction. He is presently serving as an Associate
Editor of the Journal of Pharmacology and Experimental Therapeutics.

Dr. Nahid Seyedi
I was awarded a PhD in Physiology at New York Medical College in 1994. I
then joined Dr. Levi's lab as a Postdoctoral Associate. I am presently a
Research Associate. I developed a technique for the isolation of
sympathetic nerve endings from the heart (cardiac synaptosomes). In this
model, I investigate the role of various endogenous substances that modulate
norepinephrine release from cardiac nerves. Among these substances, I
studied the effects of histamine, bradykinin and angiotensin. Presently, I
am focusing on the inhibitory role of histamine H3-receptors and
their transductional pathways. Prevention of norepinephrine release by
activation of H3-receptors on sympathetic nerve terminals is
cardioprotective in the ischemic heart.
