Targeting Homologous Recombination Addicted Tumors: Challenges And Opportunities, Talia Golan, Jonathan Brody, Md

Kimmel Cancer Center Faculty Papers

Recent advances in next generation sequencing (NGS) and molecular subtyping of tumors have opened the door to clinically available targeted therapies. Although the treatment of many solid tumors still rely on a steady regimen of non-targeted chemotherapeutic agents, it is becoming increasingly more apparent that certain tumors with defects in DNA damage repair (DDR) genes may be exquisitely sensitive to DNA damaging agents or therapies targeting key elements of this pathway such PARP1, ATR, or ATM. Still, for tumors with DDR defects the challenges are multi-fold including: (I) identifying these tumors in patients in time for a window of opportunity …

Utilizing Livers From Donors Older Than 65: A Single Center Experience, Krishnaraj Mahendraraj, Jorge H. Castro, Sean Devitt, Chad Gorn, Cataldo Doria, Adam Frank, Warren Maley, Carlo G. Ramirez

Adam M. Franks, MD

Conclusions:

Use of liver grafts from older donors presents similar survival outcomes as grafts from younger donor age. Therefore, it offers a viable option to expand the donor pool and increase number of OLTs.

However, there is higher incidence of retransplantation due to primary graft non-function, and longer hospital length of stay observed in the older donor age group.

Further studies using larger patient populations are needed to validate our results.

Department of Neurosurgery Posters

Abstract

The goal of this study was to investigate the role of the cannabinoid receptor type-2 (CB₂R) in the trigeminal pain pathway in a model of post-concussion headache. Sprague Dawley rats were randomized to receive either a repeated mild closed head injury (CHI) or served as incision controls. Changes in CGRP, nNOS, and IBA-1 were assessed in the trigeminal nucleus caudalis (TNC) and trigeminal ganglia via IHC. A subset of CHI rats received either a cannabinoid receptor type 2 (CB₂R) anti-inflammatory agonist (JWH133), an NSAID (Ketorolac), or vehicle and underwent von Frey testing for trigeminal allodynia. …

Sphingosine-1-Phosphate Promotes The Differentiation Of Adipose-Derived Stem Cells Into Endothelial Nitric Oxide Synthase (Enos) Expressing Endothelial-Like Cells., Divya Arya, Shaohua Chang, Paul J Dimuzio, Jeffrey Carpenter, Thomas N Tulenko

Department of Surgery Faculty Papers

BACKGROUND: Adipose tissue provides a readily available source of autologous stem cells. Adipose-derived stem cells (ASCs) have been proposed as a source for endothelial cell substitutes for lining the luminal surface of tissue engineered bypass grafts. Endothelial nitric oxide synthase (eNOS) is a key protein in endothelial cell function. Currently, endothelial differentiation from ASCs is limited by poor eNOS expression. The goal of this study was to investigate the role of three molecules, sphingosine-1-phosphate (S1P), bradykinin, and prostaglandin-E1 (PGE1) in ASC endothelial differentiation. Endothelial differentiation markers (CD31, vWF and eNOS) were used to evaluate the level of ASCs differentiation capability. …

Two-Vessel Off-Pump Coronary Artery Bypass Grafting By Left Thoracotomy In A Complex Redo Case, Shinya Unai, Md, Hitoshi Hirose, Md, Phd, Gary A. Cook, Pa-C, Nicholas C. Cavarocchi, Md, John W..C. Entwistle Iii, Md, Phd

Department of Surgery Faculty Papers

Introduction:

The left thoracotomy approach is an alternative technique for coronary revascularization to avoid complications associated with re-sternotomy, such as injury to patent grafts, right ventricle, aorta, during re-sternotomy. Situations such as calcification of the ascending aorta and previous mediastinitis favor the use of the left thoracotomy approach. Revascularization of the circumflex territory via a lateral thoracotomy has been reported previously. However, reports of revascularization of the LAD combined with circumflex artery territory via left thoracotomy approach are rare. We successfully performed an off-pump CABG by left thoracotomy in a complex redo case to revascularize the LAD and obtuse marginal …
