Division of Gastroenterology and Hepatology Faculty Papers

BACKGROUND & AIMS: Patients with systemic sclerosis (SSc) have impairments in gastrointestinal smooth muscle function. The disorder has been associated with circulating antibodies to cholinergic muscarinic the type-3 receptor (M(3)-R). We investigated whether it is possible to neutralize these antibodies with pooled human IgGs (pooledhIgG).

METHODS: We studied the effects of IgGs purified from patients with SSc (SScIgGs) on cholinergic nerve stimulation in rat colon tissues. We also examined the effects of SScIgGs on M(3)-R activation by bethanechol (BeCh), M(3)-R occupancy, and receptor binding using immunofluorescence, immunoblot, and enzyme-linked immunosorbent analyses of human internal anal sphincter (IAS) smooth muscle cells, …

Initial Experience With Imacor Htee-Guided Management Of Patients Following Transplant And Mechanical Circulatory Support., Christopher Kang, Hitoshi Hirose, Harold Hasting

Department of Cancer Biology Faculty Papers

We reviewed an initial experience using a miniaturized transesophageal echocardiography (TEE) probe (ImaCor, Garden City, NY) with 3 patients in whom Imacor hTEE intervention was used as a point of care device to manage extracorporeal membrane oxygenation cannula placement, cardiac hemodynamics, and post-op cardiac pathophysiology. The management of transplant or mechanical circulatory support (MCS) patients is especially challenging: transplanted hearts pose unique pathophysiological challenges, and MCS significantly alters pressure-volume-flow relationships. Real-time “hemodynamic” TEE (hTEE) can help provide effective management by direct visualization of cardiac filling and function and help guide hemodynamic management. In our initial experience, hTEE can provide point-of-care …

Trop-2 Inhibits Prostate Cancer Cell Adhesion To Fibronectin Through The Β1 Integrin-Rack1 Axis., Marco Trerotola, Jing Li, Saverio Alberti, Lucia R. Languino

Department of Cancer Biology Faculty Papers

Trop-2 is a transmembrane glycoprotein upregulated in several human carcinomas, including prostate cancer (PrCa). Trop-2 has been suggested to regulate cell-cell adhesion, given its high homology with the other member of the Trop family, Trop-1/EpCAM, and its ability to bind the tight junction proteins claudin-1 and claudin-7. However, a role for Trop-2 in cell adhesion to the extracellular matrix has never been postulated. Here, we show for the first time that Trop-2 expression in PrCa cells correlates with their aggressiveness. Using either shRNA-mediated silencing of Trop-2 in cells that endogenously express it, or ectopic expression of Trop-2 in cells that …

Sickle Cell Pain: A Critical Reappraisal., Samir K. Ballas, Kalpna Gupta, Patricia Adams-Graves

Department of Medicine Faculty Papers

Sickle cell pain includes 3 types: acute recurrent painful crises, chronic pain syndromes, and neuropathic pain. The acute painful crisis is the hallmark of the disease and the most common cause of hospitalization and treatment in the emergency department. It evolves through 4 phases: prodromal, initial, established, and resolving. Each acute painful episode is associated with inflammation that worsens with recurrent episodes, often culminating in serious complications and organ damage, such as acute chest syndrome, multiorgan failure, and sudden death. Three pathophysiologic events operate in unison during the prodromal phase of the crisis: vaso-occlusion, inflammation, and nociception. Aborting the acute …

Measuring Parvalbumin Levels In Fish Muscle Tissue: Relevance Of Muscle Locations And Storage Conditions, Poi-Wah Lee, Julie A. Nordlee, Stef J. Koppelman, Joseph L. Baumert, Steve L. Taylor

Department of Food Science and Technology: Faculty Publications

Fish is an allergenic food capable of provoking severe anaphylactic reactions. Parvalbumin is the major allergen identified in fish and frog muscles. Antibodies against fish and frog parvalbumin have been used to quantify parvalbumin levels from fish. However, these antibodies react variably with parvalbumin from different fish species. Several factors might be responsible for this variation including instability of parvalbumin in fish muscle as a result of frozen storage and differential parvalbumin expression in muscles from various locations within the whole fish. We aimed to investigate whether these factors contribute to the previously observed variable immunoreactivity of the anti-parvalbumin antibodies. …

Anaesthetic Management Of A Young Patient With Homocystinuria, Ali Asghar, Faiza Mazhar Ali

Department of Anaesthesia

Homocystinuria is a rare autosomal recessive genetic disease. It is caused by a deficiency in cystathionine-b-synthase leading to a defect in methionine metabolism. High levels of plasma homocysteine are associated with vascular injury via mechanisms of oxidative damage, vascular smooth muscle proliferation, promotion of platelet activation and aggregation,and disruption of normal procoagulant-anticoagulant balance favouring thrombosis. This is a case of 8 years old boy, a known case of homocystinuria, who was scheduled for bilateral lensectomy and intraocular lens placement. The major anaesthetic considerations include the development of thromboembolism, need to avoid nitrous oxide in balanced anaesthesia regimen and hypoglycaemia.

A Kidney For Christmas, Stephen Scholand

The Medicine Forum

When Asmar Lawrence first walked into the small examining room in the Jefferson Hospital Ambulatory Practice (JHAP) Clinic, we both had no idea what the future would hold. It was July, 1998 and I was fresh from medical school. Each week, I looked forward to the JHAP experience to develop my clinical skills and follow patients longitudinally. No longer was my learning prescribed from a textbook, this was the 'real world' of medicine where anything could happen and I was supposed to be in control of it. The long white coat probably helped perpetuate some of that illusion. Fortunately our …

Brachytherapy: A New Weapon Against Coronary Restenosis, Rob Silver

The Medicine Forum

Since its introduction in the late 1970's, coronary angioplasty has become a common procedure for treating coronary atherosclerotic disease. It offers significant improvement in symptoms of coronary artery disease through a less invasive procedure than coronary artery bypass grafting (CABG). Each year, over 500,000 percutaneous transluminal coronary angioplasty (PTCA) procedures are performed in North America alone. In larger epicardial vessels that are 3 millimeters or greater in diameter, a metal stent can be placed during angioplasty to reduce the incidence of restenosis. In fact, stents are now deployed in approximately 80 percent of PTCA procedures. The success rate of PTCA …
