Involvement Of Beta-Chemokines In The Development Of Inflammatory Demyelination., Ileana Banisor, Thomas P Leist, Bernadette Kalman

Department of Neurology Faculty Papers

The importance of beta-chemokines (or CC chemokine ligands - CCL) in the development of inflammatory lesions in the central nervous system of patients with multiple sclerosis and rodents with experimental allergic encephalomyelitis is strongly supported by descriptive studies and experimental models. Our recent genetic scans in families identified haplotypes in the genes of CCL2, CCL3 and CCL11-CCL8-CCL13 which showed association with multiple sclerosis. Complementing the genetic associations, we also detected a distinct regional expression regulation for CCL2, CCL7 and CCL8 in correlation with chronic inflammation in multiple sclerosis brains. These observations are in consensus with previous studies, and add new …

Cardiovascular Comorbidities Among Public Health Clinic Patients With Diabetes: The Urban Diabetics Study, Jessica M. Robbins, Chris N. Sciamanna, David A. Webb

College of Population Health Faculty Papers

BACKGROUND:We sought to determine the frequency and distribution of cardiovascular comorbidities in a large cohort of low-income patients with diabetes who had received primary care for diabetes at municipal health clinics.

METHODS:Outpatient data from the Philadelphia Health Care Centers was linked with hospital discharge data from all Pennsylvania hospitals and death certificates.

RESULTS:Among 10,095 primary care patients with diabetes, with a mean observation period of 4.6 years (2.8 after diabetes diagnosis), 2,693 (14.3%) were diagnosed with heart disease, including 270 (1.4%) with myocardial infarction and 912 (4.8%) with congestive heart failure. Cerebrovascular disease was diagnosed in 588 patients (3.1%). Over …

Two-Dimensional Fluorescence Difference Gel Electrophoresis Analysis Of The Urine Proteome In Human Diabetic Nephropathy, Kumar Sharma, Sohee Lee, Steven Han, Sungchun Lee, Barbara Francos, Peter Mccue, Richard Wassell, M. Alexander Shaw, Satish P. Ramachandrarao

Department of Medicine Faculty Papers

Urinary proteins may provide clues regarding pathogenesis of kidney disease as well as providing markers of disease activity. We employed two-dimensional differential in-gel electrophoretic analysis (2-D DIGE) to assess multiple urine samples in patients with diabetic nephropathy. Patient samples were collected as timed overnight collections. All the patients had longstanding diabetes, impaired renal function, and overt proteinuria. Control and patient urinary protein were analyzed by 2-D DIGE and DeCyder analysis. Ninety-nine spots were significantly regulated in the urine proteome of the diabetic samples, with 63 up- and 36 down-regulated. One spot corresponding to a pI 5–6 and a molecular weight …

Multiple Metabolic Hits Converge On Cd36 As Novel Mediator Of Tubular Epithelial Apoptosis In Diabetic Nephropathy, Katalin Susztack, Emilio Ciccone, Peter Mccue, Kumar Sharma, Erwin Böttinger

Department of Medicine Faculty Papers

Diabetic nephropathy (DNP) is a common complication of type 1 and type 2 diabetes mellitus and the most common cause of kidney failure. While DNP manifests with albuminuria and diabetic glomerulopathy, its progression correlates best with tubular epithelial degeneration (TED) and interstitial fibrosis. However, mechanisms leading to TED in DNP remain poorly understood.

Multiple Metabolic Hits Converge On Cd36 As Novel Mediator Of Tubular Epithelial Apoptosis In Diabetic Nephropathy., Katalin Susztak, Emilio Ciccone, Peter Mccue, Kumar Sharma, Erwin P Böttinger

Department of Medicine Faculty Papers

BACKGROUND: Diabetic nephropathy (DNP) is a common complication of type 1 and type 2 diabetes mellitus and the most common cause of kidney failure. While DNP manifests with albuminuria and diabetic glomerulopathy, its progression correlates best with tubular epithelial degeneration (TED) and interstitial fibrosis. However, mechanisms leading to TED in DNP remain poorly understood.

METHODS AND FINDINGS: We found that expression of scavenger receptor CD36 coincided with proximal tubular epithelial cell (PTEC) apoptosis and TED specifically in human DNP. High glucose stimulated cell surface expression of CD36 in PTECs. CD36 expression was necessary and sufficient to mediate PTEC apoptosis induced …

Palm Is Expressed In Both Developing And Adult Mouse Lens And Retina., Meryl Castellini, Louise V Wolf, Bharesh K Chauhan, Deni S Galileo, Manfred W Kilimann, Ales Cvekl, Melinda K Duncan

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Paralemmin (Palm) is a prenyl-palmitoyl anchored membrane protein that can drive membrane and process formation in neurons. Earlier studies have shown brain preferred Palm expression, although this protein is a major water insoluble protein in chicken lens fiber cells and the Palm gene may be regulated by Pax6. METHODS: The expression profile of Palm protein in the embryonic, newborn and adult mouse eye as well as dissociated retinal neurons was determined by confocal immunofluorescence. The relative mRNA levels of Palm, Palmdelphin (PalmD) and paralemmin2 (Palm2) in the lens and retina were determined by real time rt-PCR. RESULTS: In the …

Global Gene Expression Profiling Of Cells Overexpressing Smc3., Giancarlo Ghiselli, Chang-Gong Liu

Department of Microbiology and Immunology Faculty Papers

BACKGROUND: The Structural Maintenance of Chromosome 3 protein (SMC3) plays an essential role during the sister chromatid separation, is involved in DNA repair and recombination and participates in microtubule-mediated intracellular transport. SMC3 is frequently elevated in human colon carcinoma and overexpression of the protein transforms murine NIH3T3 fibroblasts. In order to gain insight into the mechanism of SMC3-mediated tumorigenesis a gene expression profiling was performed on human 293 cells line stably overexpressing SMC3. RESULTS: Biotinylated complementary RNA (cRNA) was used for hybridization of a cDNAmicroarray chip harboring 18,861 65-mer oligos derived from the published dEST sequences. After filtering, the hybridization …

Identifying Inaccuracies On Emergency Medicine Residency Applications., Eric D Katz, Lee Shockley, Lawrence Kass, David Howes, Janis P Tupesis, Christopher Weaver, Osman R Sayan, Victoria Hogan, Jason Begue, Diamond Vrocher, Jackie Frazer, Timothy Evans, Gene Hern, Ralph Riviello, Antonio Rivera, Keith Kinoshita, Edward Ferguson

Department of Emergency Medicine Faculty Papers

BACKGROUND: Previous trials have showed a 10-30% rate of inaccuracies on applications to individual residency programs. No studies have attempted to corroborate this on a national level. Attempts by residency programs to diminish the frequency of inaccuracies on applications have not been reported. We seek to clarify the national incidence of inaccuracies on applications to emergency medicine residency programs. METHODS: This is a multi-center, single-blinded, randomized, cohort study of all applicants from LCME accredited schools to involved EM residency programs. Applications were randomly selected to investigate claims of AOA election, advanced degrees and publications. Errors were reported to applicants' deans …

Referred Cutaneous Allodynia In A Migraine Patient Without Simultaneous Headache, Avi Ashkenazi, Carla Lopinto, William B. Young

Department of Neurology Faculty Papers

Cutaneous allodynia is defined as the perception of pain when a non-noxious stimulus is applied to normal skin. This phenomenon has been demonstrated in migraine patients during an acute attack. It is thought to result from central sensitization of neurons in the trigemino-vascular system and may spread to areas beyond that of the referred head pain.

In a recent study, migraine patients demonstrated increased temporal summation to painful mechanical stimuli in their referred head pain area between attacks. This suggests that changes in physiologic properties of nociceptive neurons may occur in migraine patients between attacks.

We describe a migraine patient …

Hinderin, A Five-Domains Protein Including Coiled-Coil Motifs That Binds To Smc3., Chirag A Patel, Giancarlo Ghiselli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: The structural maintenance of chromosome proteins SMC1 and SMC3 play an important role in the maintenance of chromosomal integrity by preventing the premature separation of the sister chromatids at the onset of anaphase. The two proteins are constitutive components of the multimeric complex cohesin and form dimers by interacting at their central globular regions. RESULTS: In order to identify proteins that by binding to SMC3 may interfere with the protein dimerization process, a human cDNA library was screened by the yeast two-hybrid system by using the hinge region of SMC3 as bait. This has lead to the identification of …

The Use Of Time-Resolved Fluorescence Imaging In The Study Of Protein Kinase C Localisation In Cells., Christopher D Stubbs, Stanley W Botchway, Simon J Slater, Anthony W Parker

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Two-photon-excitation fluorescence lifetime imaging (2P-FLIM) was used to investigate the association of protein kinase C alpha (PKCalpha) with caveolin in CHO cells. PKCalpha is found widely in the cytoplasm and nucleus in most cells. Upon activation, as a result of increased intracellular Ca2+ and production of DAG, through G-protein coupled-phospholipase C signalling, PKC translocates to a variety of regions in the cell where it phosphorylates and interacts with many signalling pathways. Due to its wide distribution, discerning a particular interaction from others within the cell is extremely difficult. RESULTS: Fluorescence energy transfer (FRET), between GFP-PKCalpha and DsRed-caveolin, was used …

Medical Symptoms Associated With Tobacco Smoking With And Without Marijuana Abuse Among Crack Cocaine-Dependent Patients., Ashwin A. Patkar, Vikas Batra, Paolo Mannelli, Sarah Evers-Casey, Michael J. Vergare, Frank T. Leone

Department of Psychiatry and Human Behavior Faculty Papers

Despite the widespread use of tobacco and marijuana by cocaine abusers, it remains unclear whether combined tobacco and marijuana smoking is more harmful than tobacco smoking alone in cocaine abusers. We investigated the differences in medical symptoms reported among 34 crack cocaine abusers who did not smoke tobacco or marijuana (C), 86 crack cocaine abusers who also smoked tobacco (C + T), and 48 crack abusers who smoked both tobacco and marijuana (C + T + M). Medical symptoms were recorded using a 134-item self-report instrument (MILCOM), and drug use was assessed using the Addiction Severity Index (ASI). After controlling …

Characterization Of The Chicken Inward Rectifier K+ Channel Irk1/Kir2.1 Gene., Hideki Mutai, Lawrence C Kenyon, Emily Locke, Nami Kikuchi, John Carl Oberholtzer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Inward rectifier potassium channels (IRK) contribute to the normal function of skeletal and cardiac muscle cells. The chick inward rectifier K+ channel cIRK1/Kir2.1 is expressed in skeletal muscle, heart, brain, but not in liver; a distribution similar but not identical to that of mouse Kir2.1. We set out to explore regulatory domains of the cIRK1 promoter that enhance or inhibit expression of the gene in different cell types. RESULTS: We cloned and characterized the 5'-flanking region of cIRK1. cIRK1 contains two exons with splice sites in the 5'-untranslated region, a structure similar to mouse and human orthologs. cIRK1 has …

Control Of Mitochondrial Motility And Distribution By The Calcium Signal: A Homeostatic Circuit., Muqing Yi, David Weaver, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Mitochondria are dynamic organelles in cells. The control of mitochondrial motility by signaling mechanisms and the significance of rapid changes in motility remains elusive. In cardiac myoblasts, mitochondria were observed close to the microtubular array and displayed both short- and long-range movements along microtubules. By clamping cytoplasmic [Ca2+] ([Ca2+]c) at various levels, mitochondrial motility was found to be regulated by Ca2+ in the physiological range. Maximal movement was obtained at resting [Ca2+]c with complete arrest at 1-2 microM. Movement was fully recovered by returning to resting [Ca2+]c, and inhibition could be repeated with no apparent desensitization. The inositol 1,4,5-trisphosphate- or …

Complementary Medicine In Chronic Cancer Care, Daniel A. Monti, Jingduan Yang

Marcus Institute of Integrative Health Faculty Papers

Although advancements in cancer care have led to increased cure rates and survival times, those coping with the long-term sequelae of a cancer diagnosis often report high levels of distress, poor health-related quality of life, and unmet psychosocial needs. The shortcomings of the conventional biomedical system at sufficiently addressing these chronic illness issues are a primary reason that many patients turn to complementary and alternative medicine (CAM). Although patients usually use such treatments in addition to conventional care, they often do not discuss doing so with their conventional physicians, who are perceived as being unreceptive to the topic. Physicians may …

Dynamic Mechanical (Brush) Allodynia In Cluster Headache, Avi Ashkenazi, William B. Young

Department of Neurology Faculty Papers

Cutaneous allodynia is the perception of pain when a non-noxious stimulus is applied to normal skin. It has been described in patients with migraine. Cutaneous allodynia is caused by sensitization of central nervous system neurons that receive convergent sensory input from both skin and intracranial structures. This phenomenon has not been previously described in patients with cluster headache. Although migraine and cluster headache (CH) may share some clinical features, the pathogenesis of these two primary headaches is different. The aim of this study was to examine the occurrence of dynamic mechanical (brush) allodynia (BA) in patients with CH.

Periodic Autonomic Dysfunction Without Pain In A Patient With Cluster Headache, Avi Ashkenazi, Stephen Silberstein

Department of Neurology Faculty Papers

Cluster headache (CH) is characterized by episodes of severe unilateral headache accompanied by symptoms of cranial parasympathetic hyperactivity and sympathetic dysfunction that occur in cluster periods. Positron emission tomography (PET) studies have demonstrated evidence of a central generator of CH attacks located in the posterior-inferior hypothalamus. It has been suggested that the autonomic symptoms in CH result from reflex activation of the superior salivatory nucleus secondary to activation of the trigeminal nucleus caudalis (TNC). However, several cases of CH-like symptoms with no head pain have been documented.

We describe a patient who had suffered from typical episodic CH for two …

Access To Quality Care: Links Between Evidence, Nursing Language, And Informatics, Beth Ann Swan Phd, Crnp, Norma M. Lang Phd, Rn, Faan, Frcn, Anne M. Mcginley Phd, Crnp

College of Nursing Faculty Papers & Presentations

Despite evidence on nursing’s contribution to the quality of care, much of what nurses “do” remains essentially invisible.

It is vital to recognize the need for a paradigm shift in nursing that utilizes new informatics tools required for optimum use of evidence related to the delivery of quality nursing care.

Embedding nursing language within informatics structures is essential to make the work of nurses visible, and articulate evidence about the quality and value of nursing in the care of patients, groups, and populations.

Inhibition Of Glucocorticoid-Induced Apoptosis By Targeting Splice Variants Of Bim Mrna With Small Interfering Rna And Short Hairpin Rna., Marc T. Abrams, Noreen M. Robertson, Kyonggeun Yoon, Eric Wickstrom

Department of Biochemistry and Molecular Biology Faculty Papers

Glucocorticoids (GCs) induce apoptosis in lymphocytes and are effective agents for the treatment of leukemia. The activated glucocorticoid receptor (GR) initiates a transcriptional program leading to caspase activation and cell death, but the critical signaling intermediates in GC-induced apoptosis remain largely undefined. We have observed that GC induction of the three major protein products of the Bcl-2 relative Bim (BimEL, BimS and BimL) correlates with GC sensitivity in a panel of human pre-B acute lymphoblastic leukemia (ALL) cell lines. To test the hypothesis that Bim facilitates GC-induced apoptosis, we reduced BIM mRNA levels and Bim protein levels by RNA interference …

Relationship Of Serum Prolactin With Severity Of Drug Use And Treatment Outcome In Cocaine Dependence., Ashwin A. Patkar, Paolo Mannelli, Kenneth M. Certa, Kathleen Peindl, Heather Murray, Michael J. Vergare, Wade H. Berrettini

Department of Psychiatry and Human Behavior Faculty Papers

RATIONALE: Alteration in serum prolactin (PRL) levels may reflect changes in central dopamine activity, which modulates the behavioral effects of cocaine. Therefore, serum PRL may have a potential role as a biological marker of drug severity and treatment outcome in cocaine dependence.

OBJECTIVE: We investigated whether serum PRL levels differed between cocaine-dependent (CD) subjects and controls, and whether PRL levels were associated with severity of drug use and treatment outcome in CD subjects.

METHODS: Basal PRL concentrations were assayed in 141 African-American (AA) CD patients attending an outpatient treatment program and 60 AA controls. Severity of drug use was assessed …

Occipital Nerve Block Rapidly Eliminates Allodynia Far From The Site Of Headache: A Case Report, William B. Young, Valentin Mateos, Avi Ashkenazi

Department of Neurology Faculty Papers

Seventy to 80% of persons with migraine develop allodynia during the course of a severe attack. During a migraine attack, allodynia spreads topographically to extratrigeminal territory. Dynamic mechanical allodynia, otherwise known as brush allodynia (BA), is a subtype of allodynia that is easily tested. Ashkenazi & Young recently reported on the immediate benefits of greater occipital nerve (GON) block on brush allodynia and pain in migraine and in cluster headache. In these studies, testing was performed at fixed sites in the trigeminal and cervical distributions. Allodynia in thoracic dermatomes was not studied.

Heme Oxygenase-2 Gene Deletion Attenuates Oxidative Stress In Neurons Exposed To Extracellular Hemin., Raymond F Regan, Jing Chen, Luna Benvenisti-Zarom

Department of Emergency Medicine Faculty Papers

BACKGROUND: Hemin, the oxidized form of heme, accumulates in intracranial hematomas and is a potent oxidant. Growing evidence suggests that it contributes to delayed injury to surrounding tissue, and that this process is affected by the heme oxygenase enzymes. In a prior study, heme oxygenase-2 gene deletion increased the vulnerability of cultured cortical astrocytes to hemin. The present study tested the effect of HO-2 gene deletion on protein oxidation, reactive oxygen species formation, and cell viability after mixed cortical neuron/astrocyte cultures were incubated with neurotoxic concentrations of hemin. RESULTS: Continuous exposure of wild-type cultures to 1-10 microM hemin for 14 …

Headache Management For The Pain Specialist, Avi Ashkenazi, Stephen Silberstein

Department of Neurology Faculty Papers

Headache is a common symptom caused by a wide variety of diseases. Primary headaches include migraine, cluster headache, tension-type headache and other less common diseases. It is important to differentiate these headaches from secondary headaches caused by vascular, neoplastic, infectious, metabolic and toxic disorders. Most primary headaches have a genetic basis, with environmental factors acting as triggers. Recent advances in basic research resulted in the development of more specific and effective therapies. Medication overuse headache is a very common cause of chronic daily headache. Detoxification from the offending drug is essential for headache improvement. Cervicogenic headache is common and needs …
