Expression Of Aldehyde Dehydrogenase In Dysplastic Lesions Arising From Inflammatory Bowel Disease, Adam D. Toll, Bruce M. Boman, Juan P. Palazzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Conclusion: Our study demonstrates ALDH1 is significantly expressed in dysplatic lesions arising from IBD. ALDH1-expression in cancer stem cells suggest an important causative role in the progression to cancer in IBD. Although we found high sensitivity for dysplasia, the specificity was poor. In addition to neoplasia, ALDH1-expressing stem cells proliferate in response to chronic inflammation, accounting for the cases of inflammatory atypia with positive ALDHI1 expression.

Fuzzy Logic: A “Simple” Solution For Complexities In Neurosciences?, Saniya Siraj Godil, Muhammad Shahzad Shamim, Ather Enam, Uvais Qidwai

It has the potential of combining human heuristics into computer-assisted decision making, which is applicable to individual patients as it takes into account all the factors and complexities of individuals. Fuzzy logic has been applied in all disciplines of medicine in some form and recently its applicability in neurosciences has also gained momentum.
Methods: This review focuses on the use of this concept in various branches of neurosciences including basic neuroscience, neurology, neurosurgery, psychiatry and psychology.
Results: The applicability of fuzzy logic is not limited …

Optimality In Neural Adaptation, Adrienne Fairhall

Systems Science Friday Noon Seminar Series

Nervous systems tune themselves to the statistical structure of the stimuli they encounter. This sensitivity to statistics appears in phenomena ranging over many timescales, from the adaptation of vision to a rapid change in light level to the loss of ability to distinguish the sounds of non-native languages. While multiple neural mechanisms contribute to this on-line learning of stimulus distributions, we show that the intrinsic nonlinearities of single neurons provide them with the ability to represent time-varying stimuli optimally. While such sensitivity to stimulus statistics does not require learning, slower timescales of adaptation are consistent with optimal inference of statistical …

Phase I Study Of 'Dose-Dense' Pemetrexed Plus Carboplatin/Radiotherapy For Locally Advanced Non-Small Cell Lung Carcinoma., Xinglei Shen, Albert Denittis, Maria Werner-Wasik, Rita Axelrod, Paul Gilman, Thomas Meyer, Joseph Treat, Walter J Curran, Mitchell Machtay

Department of Radiation Oncology Faculty Papers

BACKGROUND: This phase I study investigates the feasibility of carboplatin plus dose-dense (q2-week) pemetrexed given concurrently with radiotherapy (XRT) for locally advanced and oligometastatic non-small cell lung cancer (NSCLC).

METHODS: Eligible patients had Stage III or IV (oligometastatic) NSCLC. Patients received XRT to 63 Gy in standard fractionation. Patients received concurrent carboplatin (AUC = 6) during weeks 1 and 5 of XRT, and pemetrexed during weeks 1, 3, 5, and 7 of XRT. The starting dose level (level 1) of pemetrexed was 300 mg/m2. Following the finding of dose limiting toxicity (DLT) in dose level 1, an amended dose level …

Rho Activation Of Mdia Formins Is Modulated By An Interaction With Inverted Formin 2 (Inf2), Hua Sun, Johannes S. Schlondorff, Elizabeth J. Brown, Henry N. Higgs, Martin R. Pollak

Dartmouth Scholarship

Inverted formin 2 (INF2) encodes a member of the diaphanous subfamily of formin proteins. Mutations in INF2 cause human kidney disease characterized by focal and segmental glomerulosclerosis. Disease-causing mutations occur only in the diaphanous inhibitory domain (DID), suggesting specific roles for this domain in the pathogenesis of disease. In a yeast two-hybrid screen, we identified the diaphanous autoregulatory domains (DADs) of the mammalian diaphanous-related formins (mDias) mDia1, mDia2, and mDia 3 as INF2_DID-interacting partners. The mDias are Rho family effectors that regulate actin dynamics. We confirmed in vitro INF2_DID/mDia_DAD binding by biochemical assays, confirmed the in vivo interaction of these …

Pediatric Ethics Guidelines For Hereditary Medullary Thyroid Cancer, M. Sara Rosenthal, Douglas S. Diekema

Internal Medicine Faculty Publications

Hereditary medullary thyroid cancer is an aggressive cancer for which there is no standard effective systemic therapy, but which can be prevented through genetic screening and prophylactic thyroidectomy. Although this cancer accounts for roughly 17% of all pediatric thyroid cancers, a significant percentage of affected families do not "accept" screening, while many gene carriers delay or refuse prophylactic thyroid surgery for their children. Current genetic screening practices in medullary thyroid cancer are inadequate; more than 50% of index patients with hereditary medullary thyroid cancer present with a thyroid mass; up to 75% have distant metastasis. These proposed pediatric ethics guidelines …

Apotransferrin Protects Cortical Neurons From Hemoglobin Toxicity, Jing Chen-Roetling, Lifen Chen, Raymond F. Regan

Department of Emergency Medicine Faculty Papers

The protective effect of iron chelators in experimental models of intracerebral hemorrhage suggests that nonheme iron may contribute to injury to perihematomal cells. Therapy with high affinity iron chelators is limited by their toxicity, which may be due in part to sequestration of metals in an inaccessible complex. Transferrin is unique in chelating iron with very high affinity while delivering it to cells as needed via receptor-mediated endocytosis. However, its efficacy against iron-mediated neuronal injury has never been described, and was therefore evaluated in this study using an established cell culture model of hemoglobin neurotoxicity. At concentrations similar to that …

Pathogenesis, Diagnosis And Management Of Primary Melanoma Of The Colon, Umair Khalid, Taimur Saleem, Ayesha Mallick Imam, Muhammad Rizwan Khan

Department of Surgery Docs

Background:Melanomas within the alimentary tract are usually metastatic in origin. On the other hand, primary melanomas of the gastrointestinal tract are relatively uncommon. There are several published reports of melanomas occurring in the esophagus, stomach, small bowel, and anorectum. The occurrence of primary melanoma of the colon has, however, only been rarely reported. The optimum modus operandi for the management of primary colonic melanoma remains nebulous due to the limited number of reports in literature.

Methods:

A comprehensive search of Medline, Cochrane and Highwire was performed using the following keywords: 'melanoma', 'malignant melanoma', 'primary melanoma', 'colon', 'gastrointestinal tract', 'alimentary …

Detection Of Ndm-1-Producing Klebsiella Pneumoniae In Kenya., Laurent Poirel, Gunturu Revathi, Sandrine Bernabeu, Patrice Nordmann

Pathology, East Africa

Seven carbapenem-resistant NDM-1-positive Klebsiella pneumoniae isolates were recovered from patients hospitalized between 2007 and 2009 in different wards at a referral and tertiary care center in Nairobi. Most of the isolates were obtained from urine. All isolates carried the bla_NDM-1 carbapenemase gene previously reported from India, Pakistan, and the United Kingdom. These isolates were clonally related and expressed many other resistance determinants, including β-lactamases CTX-M-15, OXA-1, OXA-9, CMY-6, and aminoglycoside resistance methylase RmtC. This work corresponds to the first report of NDM-1 producers in Africa.

Primary Amebic Meningoencephalitis Caused By Naegleria Fowleri, Karachi, Pakistan., Sadia Shakoor, Mohammad Asim Beg,, Syed Faisal Mahmood, Rebecca Bandea, Rama Sriram, Fatima Noman, Farheen Ali,, Govinda S. Visvesvara, Afia Zafar

Department of Medicine

We report 13 cases of Naegleria fowleri primary amebic meningoencephalitis in persons in Karachi, Pakistan, who had no history of aquatic activities. Infection likely occurred through ablution with tap water. An increase in primary amebic meningoencephalitis cases may be attributed to rising temperatures, reduced levels of chlorine in potable water, or deteriorating water distribution systems.

Prolactin-Induced Mouse Mammary Carcinomas Model Estrogen Resistant Luminal Breast Cancer., Lisa M Arendt, Debra E Rugowski, Tara A Grafwallner-Huseth, Maria Jose Garcia-Barchino, Hallgeir Rui, Linda A Schuler

Kimmel Cancer Center Faculty Papers

INTRODUCTION: Tumors that express estrogen receptor alpha (ERα+) comprise 75% of breast cancers in women. While treatments directed against this receptor have successfully lowered mortality rates, many primary tumors initially or later exhibit resistance. The paucity of murine models of this "luminal" tumor subtype has hindered studies of factors that promote their pathogenesis and modulate responsiveness to estrogen-directed therapeutics. Since epidemiologic studies closely link prolactin and the development of ERα+ tumors in women, we examined characteristics of the aggressive ERα+ and ERα- carcinomas which develop in response to mammary prolactin in a murine transgenic model (neu-related lipocalin- prolactin (NRL-PRL)). To …

Vimentin Is A Novel Akt1 Target Mediating Motility And Invasion., Q-S Zhu, K Rosenblatt, K-L Huang, G Lahat, R Brobey, S Bolshakov, T Nguyen, Z Ding, R Belousov, K Bill, X Luo, A Lazar, Adam Dicker, Md, Phd, G B Mills, M-C Hung, D Lev

Department of Radiation Oncology Faculty Papers

The PI3K/AKT signaling pathway is aberrant in a wide variety of cancers. Downstream effectors of AKT are involved in survival, growth and metabolic-related pathways. In contrast, contradictory data relating to AKT effects on cell motility and invasion, crucial prometastatic processes, have been reported pointing to a potential cell type and isoform type-specific AKT-driven function. By implication, study of AKT signaling should optimally be conducted in an appropriate intracellular environment. Prognosis in soft-tissue sarcoma (STS), the aggressive malignancies of mesenchymal origin, is poor, reflecting our modest ability to control metastasis, an effort hampered by lack of insight into molecular mechanisms driving …

Cx3cl1 Reduces Neurotoxicity And Microglial Activation In A Rat Model Of Parkinson's Disease, Mibel M. Pabon, Adam D. Bachstetter, Charles E. Hudson, Carmelina Gemma, Paula C. Bickford

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Parkinson's disease is characterized by a progressive loss of dopaminergic neurons in the substantia nigra. The cause of the neurodegeneration is unknown. Neuroinflammation has been clearly shown in Parkinson's disease and may be involved in the progressive nature of the disease. Microglia are capable of producing neuronal damage through the production of bioactive molecules such as cytokines, as well as reactive oxygen species (ROS), and nitric oxide (NO). The inflammatory response in the brain is tightly regulated at multiple levels. One form of immune regulation occurs via neurons. Fractalkine (CX3CL1), produced by neurons, suppresses the activation of microglia. CX3CL1 …

Specific Thiazolidinediones Inhibit Ovarian Cancer Cell Line Proliferation And Cause Cell Cycle Arrest In A Pparγ Independent Manner, Linah Al-Alem, R. Chase Southard, Michael W. Kilgore, Thomas E. Curry

Pharmacology and Nutritional Sciences Faculty Publications

BACKGROUND: Peroxisome Proliferator Activated Receptor gamma (PPARγ) agonists, such as the thiazolinediones (TZDs), have been studied for their potential use as cancer therapeutic agents. We investigated the effect of four TZDs--Rosiglitazone (Rosi), Ciglitazone (CGZ), Troglitazone (TGZ), and Pioglitazone (Pio)--on ovarian cancer cell proliferation, PPARγ expression and PPAR luciferase reporter activity. We explored whether TZDs act in a PPARγ dependent or independent manner by utilizing molecular approaches to inhibit or overexpress PPARγ activity.

PRINCIPAL FINDINGS: Treatment with CGZ or TGZ for 24 hours decreased proliferation in three ovarian cancer cell lines, Ovcar3, CaOv3, and Skov3, whereas Rosi and Pio had no …

Population-Wide Model-Free Quantification Of Blood-Brain-Barrier Dynamics In Multiple Sclerosis, Russell T. Shinohara, Ciprian Crainiceanu, Brian Caffo, María Inés Gaitán, Daniel Reich

Johns Hopkins University, Dept. of Biostatistics Working Papers

The processes by which new white matter lesions in multiple sclerosis (MS) develop are only partially understood. Much of this understanding has come through magnetic resonance imaging (MRI) of the human brain. One of the hallmarks of new lesion development in MS is enhancement on T1-weighted MRI scans following the intravenous administration of a gadolinium-based contrast agent that shortens the longitudinal relaxation time of the tissue. This visible enhancement in the MRI results from the opening of the blood-brain barrier and reveals areas of active inflammation. The incidence and number of existing enhancing lesions are common outcome measures used in …

Molecular Mechanism By Which The Nucleoid Occlusion Factor, Slma, Keeps Cytokinesis In Check, Nam Ky Tonthat, Stefan T Arold, Brian F Pickering, Michael W Van Dyke, Shoudan Liang, Yue Lu, Tushar K Beuria, William Margolin, Maria A Schumacher

Faculty, Staff and Student Publications

In Escherichia coli, cytokinesis is orchestrated by FtsZ, which forms a Z-ring to drive septation. Spatial and temporal control of Z-ring formation is achieved by the Min and nucleoid occlusion (NO) systems. Unlike the well-studied Min system, less is known about the anti-DNA guillotining NO process. Here, we describe studies addressing the molecular mechanism of SlmA (synthetic lethal with a defective Min system)-mediated NO. SlmA contains a TetR-like DNA-binding fold, and chromatin immunoprecipitation analyses show that SlmA-binding sites are dispersed on the chromosome except the Ter region, which segregates immediately before septation. SlmA binds DNA and FtsZ simultaneously, and the …

Fluorine Substitutions In An Antigenic Peptide Selectively Modulate T Cell Receptor Binding In A Minimally Perturbing Manner, Kurt H. Piepenbrink, Oleg Y. Borbulevych, Ruth F. Sommese, John Clemens, Kathrynq M. Armstrong, Clare Desmond, Priscilla Do, Brian M. Baker

Food for Health: Publications

T cell receptor (TCR) recognition of antigenic peptides bound and presented by major histocompatibility complex (MHC) molecules forms the basis of the cellular immune response to pathogens and cancer. TCRs bind peptide/MHC molecules weakly and with fast kinetics, features which have hindered detailed biophysical studies of these interactions. Modified peptides resulting in enhanced TCR binding could help overcome these challenges. Further, there is considerable interest in using modified peptides with enhanced TCR binding as the basis for clinical vaccines. Here, we studied how fluorine substitutions in an antigenic peptide can selectively impact TCR recognition. Using a structure-guided design approach, we …

Short-Term And Long-Term Effects Of Orthopedic Biodegradable Implants, Ami R. Amini, James S. Wallace, Syam P. Nukavarapu

Articles - Patient Care

Presently, orthopedic and oral/maxillofacial implants represent a combined $2.8 billion market, a figure expected to experience significant and continued growth. Although traditional permanent implants have been proved clinically efficacious, they are also associated with several drawbacks, including secondary revision and removal surgeries. Non-permanent, biodegradable implants offer a promising alternative for patients, as they provide temporary support and degrade at a rate matching tissue formation, and thus, eliminate the need for secondary surgeries. These implants have been in clinical use for nearly 25 years, competing directly with, or maybe even exceeding, the performance of permanent implants. The initial implantation of biodegradable …

Anti-Saccade Performance Predicts Executive Function And Brain Structure In Normal Elders, J. B. Mirsky, H. W. Heuer, A. Jafari, J. H. Kramer, A. K. Schenk, Indre Viskontas, B. L. Miller, A. L. Boxer

Psychology

Objective—To assess the neuropsychological and anatomical correlates of anti-saccade (AS) task performance in normal elders.

Background—The AS task correlates with neuropsychological measures of executive function and frontal lobe volume in neurological diseases, but has not been studied in a well-characterized normal elderly population. Because executive dysfunction can indicate an increased risk for cognitive decline in cognitively normal elders, we hypothesized that AS performance might be a sensitive test of age-related processes that impair cognition.

Method—The percentage of correct AS responses was evaluated in forty-eight normal elderly subjects and compared with neuropsychological test performance using linear regression analysis …

Genetic Analysis Of The Neurosteroid Deoxycorticosterone And Its Relation To Alcohol Phenotypes: Identification Of Qtls And Downstream Gene Regulation, Patrizia Porcu, Todd K. O'Buckley, Soomin C. Song, Jo Lynne Harenza, Lu Lu, Xusheng Wang, Michael F. Miles, A. Leslie Morrow

Neurology Publications

Background

Deoxycorticosterone (DOC) is an endogenous neurosteroid found in brain and serum, precursor of the GABAergic neuroactive steroid (3α,5α)-3,21-dihydroxypregnan-20-one (tetrahydrodeoxycorticosterone, THDOC) and the glucocorticoid corticosterone. These steroids are elevated following stress or ethanol administration, contribute to ethanol sensitivity, and their elevation is blunted in ethanol dependence.

Methodology/Principal Findings

To systematically define the genetic basis, regulation, and behavioral significance of DOC levels in plasma and cerebral cortex we examined such levels across 47 young adult males from C57BL/6J (B6)×DBA/2J (D2) (BXD) mouse strains for quantitative trait loci (QTL) and bioinformatics analyses of behavior and gene regulation. Mice were injected with saline …

Fetal Erap2 Variation Is Associated With Preeclampsia In African Americans In A Case-Control Study, Lori D. Hill, Dashaunda D. Hilliard, Timothy P. York, Sindhu Srinivas, Juan P. Kusanovic, Ricardo Gomez, Michal A. Elovitz, Roberto Romero, Jerome F. Strauss Iii

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Preeclampsia affects 3-8% of pregnancies and is a major cause of maternal and perinatal morbidity and mortality worldwide. This complex disorder is characterized by alterations in the immune and vascular systems and involves multiple organs. There is strong evidence for a genetic contribution to preeclampsia. Two different single nucleotide polymorphisms (SNPs) in the endoplasmic reticulum aminopeptidase 2 (ERAP2) gene were recently reported to be associated with increased risk for preeclampsia in two different populations. ERAP2 is expressed in placental tissue and it is involved in immune responses, inflammation, and blood pressure regulation; making it is an attractive preeclampsia …

The Cns Microvascular Pericyte: Pericyte-Astrocyte Crosstalk In The Regulation Of Tissue Survival, Drew Bonkowski, Vladimir Katyshev, Roumen D. Balabanov, Andre Borisov, Paula Dore-Duffy

Wayne State University Associated BioMed Central Scholarship

Abstract

The French scientist Charles Benjamin Rouget identified the pericyte nearly 140 years ago. Since that time the role of the pericyte in vascular function has been difficult to elucidate. It was not until the development of techniques to isolate and culture pericytes that scientists have begun to understand the true impact of this unique cell in the maintenance of tissue homeostasis. In the brain the pericyte is an integral cellular component of the blood-brain barrier and, together with other cells of the neurovascular unit (endothelial cells, astrocytes and neurons) the pericyte makes fine-tuned regulatory adjustments and adaptations to promote …

Epistasis Between Comt And Mthfr In Maternal-Fetal Dyads Increases Risk For Preeclampsia, Lori D. Hill, Timothy P. York, Juan P. Kusanovic, Ricardo Gomez, Lindon J. Eaves, Roberto Romero, Jerome F. Strauss Iii

Obstetrics and Gynecology Publications

Preeclampsia is a leading cause of perinatal morbidity and mortality. This disorder is thought to be multifactorial in origin, with multiple genes, environmental and social factors, contributing to disease. One proposed mechanism is placental hypoxia-driven imbalances in angiogenic and anti-angiogenic factors, causing endothelial cell dysfunction. Catechol-O-methyltransferase (Comt)-deficient pregnant mice have a preeclampsia phenotype that is reversed by exogenous 2-methoxyestradiol (2-ME), an estrogen metabolite generated by COMT. 2-ME inhibits Hypoxia Inducible Factor 1α, a transcription factor mediating hypoxic responses. COMT has been shown to interact with methylenetetrahydrofolate reductase (MTHFR), which modulates the availability of S-adenosylmethionine (SAM), a COMT …

Dietary Interventions Against Mammary Glands And Prostate Cancers, Juliana Adedayo Akinsete

Theses, Dissertations and Capstones

Dietary components modulate normal cellular functions and, in cancer cells, alter processes that lead to cancer and/or its progression. The change in the patterns of human food production and consumption over time has contributed to increasing risk for diseases including cancer. Omega-3 and omega-6 fatty acids are classes of essential polyunsaturated fatty acids in the human diet and are required for normal growth and development. Omega-3 and omega-6 fats are thought to be required in the ratio of 1:1 to 1:4 on which humans are thought to have evolved. However, the Western diet has greatly shifted from this ratio. The …

Pitx2 Is Overexpressed In Follicular Cell-Derived Thyroid Cancer And Promotes Thyroid Cancer Proliferation By Regulating Cell Cycle, Yue Huang

Theses, Dissertations and Capstones

Thyroid cancer is the most prevailing malignancy of the endocrine system. Its incidence is rapidly rising at the second fastest rate of all malignancies in the United States, making it a significant health problem. Although the majority of thyroid cancer is slowly-growing and well-differentiated, available treatment options are very limited, and most of them require complete removal of the thyroid gland and surrounding tissues. Patients who have undergone thyroid removal have to take life-long hormone replacement therapy, which is very inconvenient and costly. Therefore, there is an urgent need to develop new treatments for this disease. As a prerequisite for …

Cancer Cachexia And Cardiac Atrophy In The Apcmin/+ Mice Model Of Colon Cancer, Nandini Durga Prasanna Kumar Manne

Theses, Dissertations and Capstones

Cancer cachexia is a muscle wasting condition that occurs in response to a malignant growth in the body. Cachexia is associated with heart failure and is estimated to be the immediate cause of death in about a third of all cancer patients. The purpose of this study was to investigate cardiac atrophy in the APCmin/+ mouse model of colorectal cancer. Compared to age matched C57BL/6 (BL6) mice, APCmin/+ body mass and heart mass were lower at 12 (11.1 Ѡ4.5% and 7.6 Ѡ2.8%, respectively) and 20-weeks (26.1 Ѡ2.5% and 6.0 Ѡ3.8%, respectively) of age (P < 0.05). Immunoblot analysis revealed that these changes in mass were accompanied by increased activation of protein kinase B (Akt Thr 473: 74.4 Ѡ10.9% and 216.0 Ѡ19.6% ; Akt Ser 308: 161.6 Ѡ31.7% and 367.4 Ѡ41.6% at 12- and 20-weeks, respectively, (P < 0.05)), mammalian target of rapamycin (mTOR Ser2448: 23.2 Ѡ13.2% and 44.0 Ѡ16.4% at 12- and 20-weeks, respectively, (P < 0.05)), 5' adenosine monophosphate-activated protein kinase (AMPK: 19.6 Ѡ5.2% and 22.5 Ѡ5.5% at 12- and 20-weeks, respectively, (P < 0.05)) and elevated levels of the autophagy regulator beclin1 (4.7 Ѡ3.3% and 9.5 Ѡ3.0% at 12- and 20-weeks, respectively, (P < 0.05)). No evidence of increased cardiac apoptosis, protein ubiquitination or activation of cardiac caspases or calpains was noted. Taken together, these data suggest that the cardiac atrophy that occurs in the 12- and 20-week old APCmin/+ mouse is relatively modest compared to that seen with other tumor models [1] and is associated with evidence of increased cardiac autophagy.

Predictors Of Postoperative Respiratory Failure In Patients Receiving Anesthesia, Marty Henley

Theses, Dissertations and Capstones

Introduction: Postoperative Respiratory failure has been identified as a prevention quality indicator by The Agency for Health Research and Quality (AHRQ). Postoperative Respiratory Failure is associated with increased length of stay, increased costs and increased morbidity and mortality. Unfortunately, current research is limited regarding scoring methods which are predictive for postoperative respiratory failure. This retrospective case control study was conducted to determine if the various tools of evaluation of risk currently available and to determine if any are predictive of the risk of developing postoperative respiratory failure.

Methodology: The design of this research was a retrospective case control study conducted …

Intravenous Ascorbic Acid To Prevent And Treat Cancer-Associated Sepsis?, Thomas E. Ichim, Boris Minev, Todd Braciak, Brandon Luna, Ron Hunninghake, Nina A. Mikirova, James A. Jackson, Michael J.

The history of ascorbic acid (AA) and cancer has been marked with controversy. Clinical studies evaluating AA in cancer outcome continue to the present day. However, the wealth of data suggesting that AA may be highly beneficial in addressing cancer-associated inflammation, particularly progression to systemic inflammatory response syndrome (SIRS) and multi organ failure (MOF), has been largely overlooked. Patients with advanced cancer are generally deficient in AA. Once these patients develop septic symptoms, a further decrease in ascorbic acid levels occurs. Given the known role of ascorbate in: a) maintaining endothelial and suppression of inflammatory markers; b) protection from sepsis …
