RESEARCH INTERESTS
Dr. Bailit's research focuses on how to assess and improve the quality of obstetrical care. She is interested in using risk-adjusted primary cesarean rates as a marker of quality and in examining factors that are associated with higher quality obstetrical care. Dr. Bailit works with large data sets such as birth certificate data. The overall goal of her research is to improve the quality of obstetrical care.

Research Interest
Ion channels are pores in cell membranes that transport ions at high rates. Ion channels are widespread and comprise about 15% of all known drug targets. We study their structure-function relationships, processing, regulation, genetics, and relation to disease (channelopathies). Modifier genes for hereditary and acquired (drug-induced) long QT syndrome are presently being pursued. The lab has also developed a reversible model of heart failure to study arrhythmias in this disease.

Research Interest
Dr. El-Meanawy investigates the genetics of end stage renal disease (ESRD).  He applies molecular genetics techniques to identify genes that are involved in the development or conferring susceptibility to end stage renal disease.  This laboratory uses a genetically susceptible animal model that develops spontaneous progressive renal failure.  Dissecting the gene expression patterns in the diseased and comparing that to the healthy control animals should allow the lab staff to identify genes involved in the development of ESRD.  Further study of these genes can lead to development of novel diagnostic and therapeutic modalities.

RESEARCH INTERESTS
Dr. Gonzalez's research consists of the study of women with Polycystic Ovary Syndrome (PCOS). The goal is to understand the role of inflammation in the development of insulin resistance and compensatory hyperinsulinemia in women with PCOS. A study protocol is in place to determine whether the inflammation pathway within mononuclear cells (MNC) of women with PCOS is overly upregulated culminating in excessive TNF release from MNC in response to in vitro and in vivo glucose stimulation, and whether there is a relationship between excessive TNF release from MNC and insulin secretion in women with PCOS. The study approach will also permit better discrimination between the effects of PCOS and those of obesity on the association between TNF and insulin secretion in this disorder.

The long-term goal of Dr. Haldar’s research is apoptosis  (cell suicide) inducing therapy that can be targeted for prevention of cancer.  Cancer cells have growth advantage and it is becoming clear that they also have a death advantage.  In tumors, cells that have adapted the ability to escape apoptosis (high resistance to cancer therapy) contribute to the net accumulation of tumor mass.

Research Interest
Iron-overloading and cardiac current abnormalities. Iron-induced myocardial disease is the most frequent cause of death in talassemia major and is a major life-limiting complication of transfusion-dependent refractory anemias hereditary hemochromatosis and other forms of iron overload. Our studies performed on isolated cardiomyocytes have identified iron-induced abnormalities both in overall cardiac action potential (CAP) and in specific membrane currents. In particular, we showed that iron-loaded cardiomyocytes had decreased overshoot and duration of the CAP, the Na+ current was deacreased, but K+ transient outward current was increased. The goals of our current research are to: 1) characterize the molecular basis of iron-induced abnormalities of ion currents in cardiac myocytes in culture and in a new animal model of the cardiomyopathy of iron overload, Mongolian gerbils, and 2) to determine the potential role of this abnormalities in pathophysiology of iron-overloaded heart.

Curriculum Vitae

Research Interest
Dr. Kushner is studying the molecular mechanisms by which inflammation causes the liver to increase production of an important plasma protein, C-reactive protein (CRP).  Two messenger molecules, produced at the site of inflammation, bind to receptors on the surface of liver cells, with consequent activation of several families of proteins (called transcription factors).   They move to the nucleus and cause increased CRP transaction.  The lab is defining the interactions between the transcription factors and the CRP gene.

The major area of Dr. Peckham’s research is in rehabilitation engineering and neuroprostheses.  He focuses on functional restoration of the paralyzed upper extremity in individuals with spinal cord injury.  He and collaborators have developed implantable neural prostheses that utilize electrical stimulation to control neuromuscular activation, and implemented procedures to provide control of grasp-release in individuals with tetraplegia.  This function enables individuals with central nervous system disability to regain the ability to perform essential activities of daily living.  His present efforts concern the integration of technological rehabilitation and surgical approaches to restore functional capabilities.

Research Interest
Mechanisms of cardiac arrhythmias. Areas of special interest include application of patch-clamp technologies and molecular biological methods to investigations of the mechanisms for arrhythmogenesis that involves action potential alternans, Brugada Syndrome, and LQT3.

Research Interest
Dr. Wang is interested in signaling events governing cell migration and proliferation.  Precise control of the processes is fundamental in development, whereas deregulation is linked to inflammation and tumor metastasis.   The lab has identified signaling pathway linking Eph kinase activation to inhibition of cell migration and proliferation.  Another focus in the lab is development of new therapeutics based on peptides selected from phage display libraries.
