Complex Regional Pain Syndrome: A Review Of Current Treatments, Yosef Lewis

The Science Journal of the Lander College of Arts and Sciences

Complex Regional Pain Syndrome (CRPS) is a syndrome that develops infrequently in patients that experience a minor or severe trauma to a bodily extremity. CRPS has two subtypes; Type-I and II, both are clinically characterized by hyperalgesia. During its acute stage, CRPS hyperalgesia is clinically characterized by edema in the subcutaneous tissues of the epidermis, allodynia, and localized bone resorption. In the later chronic stage, hyperalgesia is aroused by the disregulation of blood flow to the extremity and permanent dystonic and trophic changes to the skin. Because the epidemiology and central causation of CRPS remains unknown until today, health professionals …

Is There An Alternative Way Of Treating Drug Resistant Epilepsy? The Effects Of The Ketogenic Diet In Children With Intractable Epilepsy, Chaya M. Weinberg

The Science Journal of the Lander College of Arts and Sciences

Many children with epilepsy experience seizures that cannot be resolved with medication. Since surgical intervention is not always an option, the ketogenic diet (KD). a high fat, low carbohydrate and protein diet, offers a chance for seizure reduction and in some cases freedom from seizures and medication. Side effects do exist, although none are serious. Efficacy has been proven through many studies. The mechanism of the KD's effectiveness is still unknown, although several hypotheses exist, including the theory that ketone bodies themselves are anticonvulsant, and the hypothesis that glucose restriction stops seizures. Adenosine A1 receptors are also thought to have …

Huntington's Disease And Its Effect On The Brain, Shaina Rivkin-Drizin

The Science Journal of the Lander College of Arts and Sciences

Huntington's disease is a neurodegenerative disease that leads to gradual extensive brain damage, especially in the striatum and the cerebral cortex. Initial symptoms are cognitive difficulties, loss of motor contra and sudden mood imbalances. Cognitive function slowly declines into dementia, coupled with behavioral and psychiatric problems. Sufferers die within 20 years due to illness complications: a fall, pneumonia, or heart disease (Walker, 2007). This paper reviews the principle biological cause of the disease, its effect on the brain, diagnosis, and treatment.

Effects Of Intranasally Administered Dnsp-11 On The Central Dopamine System Of Normal And Parkinsonian Fischer 344 Rats, James H. Sonne

Theses and Dissertations--Neuroscience

Due to the blood-brain barrier, delivery of many drugs to the brain has required intracranial surgery which is prone to complication. Here we show that Dopamine Neuron Stimulating Peptide 11 (DNSP-11), following non-invasive intranasal administration, protects dopaminergic neurons from a lesion model of Parkinson’s disease in the rat. A significant and dose-dependent increase in an index of dopamine turnover (the ratio of DOPAC to dopamine) was observed in the striatum of normal young adult Fischer 344 rats by whole-tissue neurochemistry compared to vehicle administered controls.

Among animals challenged with a moderate, unilateral 6-hydroxy-dopamine (6-OHDA) lesion of the substantia nigra, those …

Molecular And Cellular Characterization Of Dopamine Neuron Stimulating Peptides, Kristen Kelps

Theses and Dissertations--Neuroscience

Parkinson’s disease, the second most common neurodegenerative disease, is characterized by the loss of dopaminergic neurons within the substantia nigra. Currently, the treatments available for PD are symptomatic treatments that do not stop the progression of the disease. Trophic molecules, such as glial cell-line derived neurotrophic factor (GDNF), have been evaluated as potential therapeutic molecules that could stop the loss of neurons and potentially restore some of the neurons that have already been lost. However, these trophic molecules are large making them difficult to produce and delivery. Here we characterize three peptides (DNSP-5, DNSP-11, and DNSP-17) to determine it they …

A Machine Learning Approach To Diagnosis Of Parkinson’S Disease, Sumaiya F. Hashmi

CMC Senior Theses

I will investigate applications of machine learning algorithms to medical data, adaptations of differences in data collection, and the use of ensemble techniques.

Focusing on the binary classification problem of Parkinson’s Disease (PD) diagnosis, I will apply machine learning algorithms to a primary dataset consisting of voice recordings from healthy and PD subjects. Specifically, I will use Artificial Neural Networks, Support Vector Machines, and an Ensemble Learning algorithm to reproduce results from [MS12] and [GM09].

Next, I will adapt a secondary regression dataset of PD recordings and combine it with the primary binary classification dataset, testing various techniques to consolidate …

A Dna Computer For Glioblastoma Multiforme Diagnosis And Drug Delivery, Sumaiya F. Hashmi

CMC Senior Theses

Glioblastoma multiforme (GBM) is a debilitating malignant brain tumor with expected patient survival of less than a year and limited responsiveness to most treatments, often requiring biopsy for diagnosis and invasive surgery for treatment. We propose a DNA computer system, consisting of input, computation, and output components, for diagnosis and treatment. The input component will detect the presence of three GBM biomarkers: vascular endothelial growth factor (VEGF), caveolin-1α (CAV), and B2 receptors. The computation component will include indicator segments for each of these genes, and ensure that output is only released if all the biomarkers are present. The output component …

Oxysterols And Parkinson´S Disease. Evidence That Levels Of 24s-Hydroxycholesterol In Cerebrospinal Fluid Correlates With The Duration Of The Disease., Steve Meaney, Anita Lovgren-Sandblom, Lovisa Brodin, Lisette Salveson, Valerio Leoni, Kristian Winge, Sven Palhagen, Per Svenninson

Articles

Oxysterols are important for cholesterol homeostasis in the brain and may be affected in neurodegenerative diseases. The levels of the brain-derived oxysterol 24S-hydroxycholesterol (24S-OH) have been reported to be markedly reduced in the circulation of patients with Parkinson's disease (PD) (Lee et al., Antioxid. Redox Signal. 11 (2009) 407–420). The finding is surprising in view of the fact that other neurodegenerative diseases are associated with relatively modest effects on the circulating levels of 24S-OH. We determined the plasma and cerebrospinal fluid (CSF) levels of 24S-OH and 27-hydroxycholesterol (27-OH) in patients with PD with different disease duration using a highly accurate …

Naturally Occurring Carboxypeptidase A6 Mutations: Effect On Enzyme Function And Association With Epilepsy, Matthew R. Sapio, Annick Salzmann, Monique Vessaz, Arielle Crespel, Peter J. Lyons, Alain Malafosse, Lloyd D. Fricker

Faculty Publications

Carboxypeptidase A6 (CPA6) is a member of the A/B subfamily of M14 metallocarboxypeptidases that is expressed in brain and many other tissues during development. Recently, two mutations in human CPA6 were associated with febrile seizures and/or temporal lobe epilepsy. In this study we screened for additional CPA6 mutations in patients with febrile seizures and focal epilepsy, which encompasses the temporal lobe epilepsy subtype. Mutations found from this analysis as well as CPA6 mutations reported in databases of single nucleotide polymorphisms were further screened by analysis of the modeled proCPA6 protein structure and the functional role of the mutated amino acid. …

Pharmacokinetics And Brain Uptake In The Rhesus Monkey Of A Fusion Protein Of Arylsulfatase A And A Monoclonal Antibody Against The Human Insulin Receptor, Ruben J. Boado, Jeff Zhiqiang Lu, Eric Ka-Wai Hui, Rachita K. Sumbria, William M. Pardridge

Pharmacy Faculty Articles and Research

Metachromatic leukodystrophy (MLD) is a lysosomal storage disorder of the brain caused by mutations in the gene encoding the lysosomal sulfatase, arylsulfatase A (ASA). It is not possible to treat the brain in MLD with recombinant ASA, because the enzyme does not cross the blood-brain barrier (BBB). In the present investigation, a BBB-penetrating IgG-ASA fusion protein is engineered and expressed, where the ASA monomer is fused to the carboxyl terminus of each heavy chain of an engineered monoclonal antibody (MAb) against the human insulin receptor (HIR). The HIRMAb crosses the BBB via receptor-mediated transport on the endogenous BBB insulin receptor, …
