Protein Modification By Arginylation, Hideko Kaji, Akira Kaji

Department of Biochemistry and Molecular Biology Faculty Papers

The modification of protein by arginine catalyzed by arginyltransferases (ATE1) described by the Kashina group in this issue shows that arginylation of protein occurs widely in biology and is being recognized as a key regulatory reaction such as phosphorylation of proteins (Wang et al., 2011).

Mitochondrial Genome Sequence Analysis: A Custom Bioinformatics Pipeline Substantially Improves Affymetrix Mitochip V2.0 Call Rate And Accuracy., Hongbo M Xie, Juan C Perin, Theodore G Schurr, Matthew C Dulik, Sergey I Zhadanov, Joseph A Baur, Michael P King, Emily Place, Colleen Clarke, Michael Grauer, Jonathan Schug, Avni Santani, Anthony Albano, Cecilia Kim, Vincent Procaccio, Hakon Hakonarson, Xiaowu Gai, Marni J Falk

Department of Biochemistry and Molecular Biology Faculty Papers

BACKGROUND: Mitochondrial genome sequence analysis is critical to the diagnostic evaluation of mitochondrial disease. Existing methodologies differ widely in throughput, complexity, cost efficiency, and sensitivity of heteroplasmy detection. Affymetrix MitoChip v2.0, which uses a sequencing-by-genotyping technology, allows potentially accurate and high-throughput sequencing of the entire human mitochondrial genome to be completed in a cost-effective fashion. However, the relatively low call rate achieved using existing software tools has limited the wide adoption of this platform for either clinical or research applications. Here, we report the design and development of a custom bioinformatics software pipeline that achieves a much improved call rate …

Ventral Hernia Repairs: 10 Year Single Institution Review At Thomas Jefferson University Hospital, Frederick C. Sailes, Md, Jason Walls, Md, Daria Guelig, Md, Mike Mirzabeigi, Ma, William D.

Department of Surgery Faculty Papers

Abstract

Background Definitive repair of recurrent ventral hernias using abdominal wall reconstruction techniques is an essential tool in the armentarium for general and plastic surgeons. Ramirez 1 et al describes the “component separation” technique to mobilize the rectus-abdominus internal oblique and external oblique flap to correct the defect. The recurrence rate of incisional hernias increases to 20% after gastric bypass or extensive weight loss.2 The incidence of ventral hernias after failed recurrent hernia repair increases to 40%.3 It has been reported that utilizing the sliding myofascial flap repair technique, the recurrence rate was reduced to 8.5%.4

Tdp-43 Potentiates Alpha-Synuclein Toxicity To Dopaminergic Neurons In Transgenic Mice., Tian Tian, Cao Huang, Jianbin Tong, Ming Yang, Hongxia Zhou, Xugang Xia

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

TDP-43 and α-synuclein are two disease proteins involved in a wide range of neurodegenerative diseases. While TDP-43 proteinopathy is considered a pathologic hallmark of sporadic amyotrophic lateral sclerosis and frontotemporal lobe degeneration, α-synuclein is a major component of Lewy body characteristic of Parkinson's disease. Intriguingly, TDP-43 proteinopathy also coexists with Lewy body and with synucleinopathy in certain disease conditions. Here we reported the effects of TDP-43 on α-synuclein neurotoxicity in transgenic mice. Overexpression of mutant TDP-43 (M337V substitution) in mice caused early death in transgenic founders, but overexpression of normal TDP-43 only induced a moderate loss of cortical neurons in …

Dyssynchrony In Obese Subjects Without A History Of Cardiac Disease Using Velocity Vector Imaging, Bhaskar Purushottam Md, Anoop C. Parameswaran Md, Mph, Vincent M. Figueredo Md

Division of Cardiology Faculty Papers

Abstract

Aim: To examine the occurrence of intra-left ventricular (LV) dyssynchrony in obese versus non-obese subjects without known cardiac disease using velocity vector imaging (VVI).

Methods: One hundred ninety consecutive subjects with no known cardiac disease had their echocardiograms analyzed using VVI after excluding subjects with QRS duration >120ms or LV ejection fraction (LVEF) <55%. Study subjects were divided into two groups based on body mass index (BMI): obese (BMI >30 kg/m2) and non-obese (BMI <30 kg>/m2).

Results: The final cohort included 136 subjects (74 were obese), 32% female and mean age 55 + 16 years. Occurrence of intra LV dyssynchrony was higher in the obese compared to non-obese group.

Conclusions: There was an increased prevalence of …

Acetate Causes Alcohol Hangover Headache In Rats, Christina R. Maxwell, Rebecca Jay Spangenberg, Jan B. Hoek, Stephen D. Silberstein, Michael L. Oshinsky

Department of Neurology Faculty Papers

Background

The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

Methods

We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

Results

Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

Phosphorylation Meets Nuclear Import: A Review., Jonathan D Nardozzi, Kaylen Lott, Gino Cingolani

Department of Biochemistry and Molecular Biology Faculty Papers

Phosphorylation is the most common and pleiotropic modification in biology, which plays a vital role in regulating and finely tuning a multitude of biological pathways. Transport across the nuclear envelope is also an essential cellular function and is intimately linked to many degeneration processes that lead to disease. It is therefore not surprising that phosphorylation of cargos trafficking between the cytoplasm and nucleus is emerging as an important step to regulate nuclear availability, which directly affects gene expression, cell growth and proliferation. However, the literature on phosphorylation of nucleocytoplasmic trafficking cargos is often confusing. Phosphorylation, and its mirror process dephosphorylation, …

Psychiatric Comorbidity In Transformed Migraine: Presentation, Treatment, Impact And Outcome, Muhammad A. Abbas M.D, Haseeba Ismaiel, M.D, William B. Young M.D., Mary Hopkins, Stephen D. Silberstein, M.D

Jefferson Journal of Psychiatry

Transformed migraine is one of the subtypes of chronic daily headache (CDH), and is similar to chronic migraine, described in the new International Headache Society (IHS) classification 2004. The term CDH refers to the Headache disorders experienced 15 or more days a month and includes headaches associated with medication overuse. CDH can be divided into primary and secondary varieties. Primary CDH is not related to a structural or systemic illness. It includes diseases such as Transformed migraine (TM). Chronic tension-type headache (CTTH), new daily persistent headache (NDPH), and hemicrania continua (HC). Secondary CDH has an identifiable underlying cause, including post-traumatic …

Resident Teaching Expectations And Medical Student Feedback, Michael Ignatowski

Jefferson Journal of Psychiatry

Objective Much of resident teaching of medical students occurs in an informal manner, with bedside teaching a common focus. Hence, the ability to monitor such teaching is limited. Feedback about how students perceive the teaching is perhaps one way to more effectively monitor and influence resident teaching.

Ten Year Follow Up Of A Psychiatry Residency Program Merger, Alvi A. Azad, Julianne Flynn, Thomas Matthews, Kenneth Matthews, Joseph Chozinski

Jefferson Journal of Psychiatry

Objective: To report on the successful merger of a civilian and military psychiatry residency. Methods: The reasons for and the history of the merger between the University of Texas Health Science Center at San Antonio and Wilford Hall Air Force Medical Center psychiatry residencies is described. Results: After some false starts, a bottom-up approach was implemented by first merging seminars, then rotations. Conclusions: Combining two psychiatry residencies in order to capitalize on both their strengths can yield a product even greater than the sum of their two programs and the key to a lasting merger is to start with two …

Stage Of Diagnosis Of Breast Cancer And Socioeconomic Status In A Universal Healthcare System: A Population-Based Study In Emilia-Romagna, Italy., Daniel Friedberg

Master of Public Health Capstone Presentations

Research has shown that lower socioeconomic status (SES) is associated with later stage of diagnosis of breast cancer in the United States healthcare system, where access to services may be an issue. However, limited data exists as to whether this effect is present in a universal healthcare system, without financial barriers to services. We sought to determine the association between stage of diagnosis of breast cancer and SES using data from Emilia-Romagna, a large region in northern Italy. We identified a population of women with incident breast cancer from 2002-2003 regional cancer registries, including information on cancer stage based on …

The Gucy2c Tumor Suppressor Is The Nexus Of A Paracrine Hormone Axis Preventing Radiotherapy-Induced Gastrointestinal (Gi) Toxicity, E. J. Wuthrick, P. Li, J. E. Lin, A. P. Dicker, D. Leeper, S. A. Waldman

Bodine Journal

Purpose/Objective: Radiation-induced GI toxicity is the primary dose limitation compromising therapy in cancer patients treated with radiation therapy. GUCY2C is the intestinal receptor for diarrheagenic bacterial enterotoxins and the endogenous paracrine hormones guanylin and uroguanylin. Following genomic insult, cyclic (c)GMP produced by ligand activation of GUCY2C enhances DNA damage sensing and repair in intestinal cells. Here, we show that the GUCY2C-cGMP axis mediates p53-dependent radioprotection of intestinal epithelial cells.

Potential For Dose-Escalation In The Post-Prostatectomy Setting With Intensitymodulated Radiation Therapy: A Dosimetric Study Using Eortc Consensus Guidelines For Target Volume Contours, M. Studenski, A. Harrison, S. Anamalayil, A. Harvey, E. Trabulsi, Y. Xiao, Y. Yu, A. P. Dicker, T. N. Showalter

Bodine Journal

Purpose: Radiation therapy (RT) is delivered after radical prostatectomy (RP) for prostate cancer (PC). Although intensity modulated radiation therapy (IMRT) has become standard in definitive RT for PC, dosimetric data in support of post-RP IMRT are limited. This study was designed to quantify benefits of IMRT versus 3D conformal RT (3DCRT) with respect to dose sparing of rectum and bladder and target volume coverage. Motivated by the desire to deliver higher radiation doses and to quantify the dosimetric impact of IMRT, we retrospectively analyzed images in order to: 1) identify a preferred IMRT beam arrangement; 2) evaluate the dosimetric advantages …

Costs Of Early Adjuvant Radiation Therapy After Radical Prostatectomy: A Decision Analysis, T. N. Showalter, K. A. Foley, E. Jutkowitz, C. Lallas, A. J. Harvey, E. J. Trabulsi, L. G. Gomella, A. P. Dicker, L. T. Pizzi

Bodine Journal

Purpose/Objective(s): Prospective, randomized trials support adjuvant radiation therapy (RT) for adverse pathologic features after radical prostatectomy (RP). However, adjuvant RT is not universally delivered in this setting. Criticisms of adjuvant RT include toxicity, financial costs, potential overtreatment, and effectiveness of salvage RT. The objective of this study was to construct a decision analytic model to estimate real world cost of RT vs. no RT within the context of the effectiveness of early adjuvant RT for prostate patients based on published clinical results of the Southwest Oncology Group prospective trial of adjuvant RT (SWOG 8794).

Intensity Modulated Radiation Therapy Compared With 3d Conformal Radiotherapy For Craniospinal Irradiation In Adults – Do We Gain Anything?, X. Shen, M. Studenski, A. Harrison, Y. Xiao, T. Biswas

Bodine Journal

Purpose: Craniospinal irradiation (CSI) remains one of the most technically challenging planning processes in radiation oncology due to its long shape especially in adults and complex target volume. In addition, CSI is associated with significant acute and late morbidities. We undertook a dosimetric analysis to determine if intensity modulated radiation therapy (IMRT) could improve target coverage while sparing normal tissue structures compared to classic 3D conformal radiation (3D‐CRT) planning.

Prophylactic Radiation Therapy Is Safe And Effective Treatment For The Prevention Of Recurrent Heterotopic Ossification In Elbow And Knee Joints, M. V. Mishra, L. Austin, J. Parvisi, M. Ramsey, T. N. Showalter

Bodine Journal

Background: Background Prophylactic radiation therapy (RT) is an established adjuvant therapy for heterotopic ossification (HO) of the hip when delivered in the immediate pre- or post-operative setting. Its role in prevention of recurrence after excision of HO is supported by randomized trials for HO of the hip, but there is scant evidence to support a similar approach in non-hip joints. In the current study, we evaluate radiologic and functional outcomes after prophylactic radiation therapy (RT) for prevention of HO of the knee and upper extremity [elbow and metacarpophalangeal (MCP) joints].

Evolving Role Of Vorinostat Combined With Radiation Therapy In The Treatment Of Brain Tumors, From The Lab To The Clinic, Y. R. Lawrence, P. Wachsberger, Y. Liu, B. Andersen, A. P. Dicker

Bodine Journal

Purpose/Objective(s): Radiation therapy (RT) is a critical element in the treatment of both brain metastases and glioblastoma (GBM). Temozolomide (TMZ) has an established role in the upfront treatment of GBM. Down-regulated mismatch repair (MMR) is a known mechanism of resistance to TMZ. Vorinostat (SAHA), an HDAC inhibitor, has successfully been combined with a number of cytotoxic agents, including ionizing radiation (IR). We performed a series of preclinical and clinical studies to examine the role of SAHA in the treatment of brain tumors.
