A Novel And Generalizable Organotypic Slice Platform To Evaluate Stem Cell Potential For Targeting Pediatric Brain Tumors., Shengwen Calvin Li, William Gunter Loudon

Department of Cancer Biology Faculty Papers

Brain tumors are now the leading cause of cancer-related deaths in children under age 15. Malignant gliomas are, for all practical purposes, incurable and new therapeutic approaches are desperately needed. One emerging strategy is to use the tumor tracking capacity inherent in many stem cell populations to deliver therapeutic agents to the brain cancer cells. Current limitations of the stem cell therapy strategy include that stem cells are treated as a single entity and lack of uniform technology is adopted for selection of clinically relevant sub-populations of stem cells. Specifically, therapeutic success relies on the selection of a clinically competent …

Idiopathic Epilepsy Of Childhood And Potassium Ion Channels, Alper I. Dai, Mohammad Wasay

Department of Medicine

Potassium can affect the development of common seizure type and can be defined seizure susceptibility allele. The existence of inward-rectifying potassium (Kir) channels was first recognized half a century ago. The biophysical fingerprint of Kir channels is inward rectification in the current-voltage relationship , which limits potassium efflux at depolarizing membrane potentials. Kir channels are essential in the control of resting membrane potential, coupling of the metabolic cellular state with membrane excitability, and maintenance of potassium homeostasis. The critical interval contains several candidate genes, one of which, KCNJ10, exhibits a potentially important polymorphism with regard to fundamental aspects of seizure …

Acute Stroke Secondary To Internal Carotid Artery Pseudoaneurysm: Mri Findingsand Treatment With Endovascularcoiling, Mohammad Wasay, Alper Dai, Neeraj Dubey, Saadat Kamran

Department of Medicine

Internal carotid artery pseudoaneurysms are uncommon. We report a young man with history of trivialtrauma who presented with middle cerebral artery stroke.Head CT scan revealed a right parapharyngeal mass. MRI confirmed the diagnosis of internal carotidpseudoaneurysm. Cerebral angiogram showed dissection of internal carotid artery with a large pseudoaneurysm and almost complete occlusion of vessel distal to aneurysm.Vessel was obliterated by fibercoiling and gluing byendovascular technique to diminish risk of furthere mbolization. MRI characteristics of carotid pseudoaneurysms and role of endovascular treatment arediscussed.

Herpes Simplex Virus 1 And Chlamydophila (Chlamydia) Pneumoniae Promote Ab 1-42 Amyloid Processing In Murine Astrocytes Linking An Infectious Process To Alzheimer's Disease, Laura R. Triplett, Adam L. Dore, Kevin S. Kralik, Brian J. Balin, Susan T. Hingley, Denah M. Appelt

Scholarly Posters

Background: Several studies have suggested an infectious etiology for Alzheimer's disease (AD). Previously, our laboratory identified Chlamydia pneumoniae (Cpn) from autopsied sporadic AD brains, as well as developed a BALB/c mouse model that demonstrated infection-induced amyloid plaques similar to those found in AD. Hypothesis: We propose that an additional pathogen such as herpes simplex virus type 1 (HSV1), also may be a contributing factor in toin the pathology seen in AD. HSV1, in addition to Cpn, may be triggering the abnormal cleavage of the beta amyloid precursor protein (bAPP) into Ab1-42 , thereby contributing to amyloid plaque formation. Our current …

Su.32. Myelin-Specific Regulatory T Cells Accumulate In The Central Nervous System, But Fail To Suppress Pathogenic Effector T Cells At The Peak Of Autoimmune Inflammation [Abstract Only], Thomas Korn, Mohamed Oukka, Jay Reddy, Estelle Betelli, Amit Awasthi, Raymond Sobel, Kai Wucherpfennig, Vijay K. Kuchroo

Jay Reddy Publications

Treatment with ex vivo generated regulatory T cells (Treg) has been regarded as highly attractive therapeutic approach for autoimmune diseases. However, the dynamics and function of T-reg in autoimmunity are not well understood. Thus, we developed Foxp3gfp “knock-in” mice and myelin oligodendrocyte glycoprotein (MOG)35–55/IAb tetramers to track autoantigen-specific effector T cells (T-eff) and T-reg in vivo during experimental autoimmune encephalomyelitis, an animal model for multiple sclerosis. Following immunization with the encephalitogenic peptide MOG35–55 emulsified in complete Freund's adjuvant, MOG35–55-tetramer-reactive, Foxp3+ T-reg expanded in the peripheral lymphoid compartment and readily accumulated in the central nervous system (CNS), but did not prevent …

OBJECTIVE: Glioblastoma multiforme (GBM) is a devastating brain tumor for which there is no cure. Adenoviral-mediated transfer of conditional cytotoxic (herpes simplex virus [HSV] 1-derived thymidine kinase [TK]) and immunostimulatory (Fms-like tyrosine kinase 3 ligand [Flt3L]) transgenes elicited immune-mediated long-term survival in a syngeneic intracranial GBM model in rodents. However, the lack of a large GBM animal model makes it difficult to predict the outcome of therapies in humans. Dogs develop spontaneous GBM that closely resemble the human disease; therefore, they constitute an excellent large animal model. We assayed the transduction efficiency of adenoviral vectors (Ads) encoding beta-galactosidase (betaGal), TK, …

A National Estimate Of The Cost Of Illness In Parkinson's Disease Using Retrospective Data Analysis, Katherine Anderson

Theses and Dissertations (ETD)

The purpose of this study was to estimate the cost of illness of Parkinson’s disease in the United States. Direct medical expenditures, with the exception of nursing home costs, were estimated using data from the 1999-2003 Medical Expenditures Panel Survey Household Component (MEPS-HC). Nursing home costs were estimated using the Medical Expenditures Panel Survey Nursing Home Component (MEPS-NHC). Indirect costs for lost productivity due to missed work or bed-days (morbidity) were estimated using the MEPS-HC and the Bureau of Labor Statistics (BLS). Indirect costs for lost productivity due to death (mortality) were estimated using the National Vital Statistics System.

Mechanism Of Neuronal Injury In Cerebral Venous Thrombosis, Uzma Usman, Mohammad Wasay

Department of Medicine

The impact of CVT on the brain is wide spectrum, ranging from completely normal parenchyma to brain oedema and/or haemorrhage. Multiple factors relate to neuronal injury in CVT including; dural sinus pressure, increased venous flow velocities, collateralization of venous channels, rate of occlusion, development of cytotoxic and vasogenic oedema, recanalization and accelerated myelination. It is suggested that recanalization of occluded vein, as well as, the presence or absence and the efficiency of intracranial venous collaterals, may have an impact on the extent of brain tissue damage and hence the prognosis of acute CVT.

Botulinum Toxin Type-A In The Management Of Cerebral Palsy: Low Or High Dose?, Alper I. Dai, Mohammad Wasay

Department of Medicine

Cerebral palsy is the most common cause of severe physical disability in childhood. Spasticity is a common and disabling symptom for many patients with cerebral palsy. Therapy for spasticity is symptomatic with the aim of increasing functional capacity and relieving discomfort. Spasticity treatment by orally administered drugs and intramuscular chemodenervation agents has become more frequent. Most oral medications to treat spasticity have been inadequately studied in children, especially those with cerebral palsy. Since its first use in pediatric patients, reported in 1993, botulinum toxin (BTX-A), a relatively recent addition to the available medical interventions for children with cerebral palsy, has …

Central Nervous System Involvement In Dengue Viral Infection, Romasa Channa, Mohammad Wasay

Neurological manifestations of dengue infection are rare. This review includes data regarding the epidemiology of the disease, neurological manifestations,pathogenesis, diagnosis and prognosis. It is based on 9 original articles and 10 case reports, adding up to 200 cases of dengue fever with neurological manifestations. Relevant cases have been reported from Asia, the Pacific rim, the Americas, the Mediterranean region, and Africa. A wide range of neurological manifestations has been reported. Altered consciousness and seizure are among the more common manifestations. The exact pathogenesis of this disease has not yet been established. However, recent studies hypothesize that the virus is neurotropic. …

Wernekink Comissure Syndrome: A Rare Midbrain Syndrome Secondary To Stroke, Alper I. Dai, Mohammad Wasay

Department of Medicine

Wernekink commissure involves the decussation of superior cerebellar peduncle (SCP) in midbrain. We report an elderly hypertensive, diabetic man who developed slurred speech, ataxia, and internuclear ophthalmoplegia. MRI examination revealed an unusual ischemic stroke involving Wernekink commissure. This rare stroke pattern involving decussation of SCP occurs in the setting of small arterial disease. The association between the anatomic location of the stroke and clinical findings is noteworthy.

Abdominal Pain With Rigidity Secondary To The Anti-Emetic Drug Metoclopramide, Nadeem Ullah Khan, Junaid A. Razzak

Department of Emergency Medicine

We report a case of abdominal pain with rigidity, mimicking an acute abdomen, caused by metoclopramide, a common anti-emetic drug. Extrapyramidal symptoms are commonly reported side-effects of this medication. They generally include involuntary movements of limbs, torticollis, oculogyric crisis, rhythmic protrusion of tongue, trismus, or dystonic reactions resembling tetanus, etc. Abdominal rigidity due to this medication, resembling an acute abdomen, has not been reported previously. This case report illustrates the importance of considering medication side-effects when evaluating a patient with abdominal pain and rigidity.

Heme Deficiency In Alzheimer's Disease: A Possible Connection To Porphyria, Barney E. Dwyer, Meghan L. Stone, Xiongwei Zhu, George Perry, Mark A. Smith

Dartmouth Scholarship

Mechanisms that cause Alzheimer's disease (AD), an invariably fatal neurodegenerative disease, are unknown. Important recent data indicate that neuronal heme deficiency may contribute to AD pathogenesis. If true, factors that contribute to the intracellular heme deficiency could potentially alter the course of AD. The porphyrias are metabolic disorders characterized by enzyme deficiencies in the heme biosynthetic pathway. We hypothesize that AD may differ significantly in individuals possessing the genetic trait for an acute hepatic porphyria. We elaborate on this hypothesis and briefly review the characteristics of the acute hepatic porphyrias that may be relevant to AD. We note the proximity …
