The Drosophila Homolog Of The Intellectual Disability Gene Acsl4 Acts In Glia To Regulate Morphology And Neuronal Activity: A Dissertation, Caitlin M. Quigley 2016 University of Massachusetts Medical School

The Drosophila Homolog Of The Intellectual Disability Gene Acsl4 Acts In Glia To Regulate Morphology And Neuronal Activity: A Dissertation, Caitlin M. Quigley

GSBS Dissertations and Theses

Recent developments in neurobiology make it clear that glia play fundamental and active roles, in the adult and in development. Many hereditary cognitive disorders have been linked to developmental defects, and in at least two cases, Rett Syndrome and Fragile X Mental Retardation, glia are important in pathogenesis. However, most studies of developmental disorders, in particular intellectual disability, focus on neuronal defects. An example is intellectual disability caused by mutations in ACSL4, a metabolic enzyme that conjugates long-chain fatty acids to Coenzyme A (CoA). Depleting ACSL4 in neurons is associated with defects in dendritic spines, a finding replicated in patient ...


The Effect Of Luteolin On Human Glioblastoma, David M. Anson, Samson Amos, Robert L. Paris, Denise S. Simpson 2016 Cedarville University

The Effect Of Luteolin On Human Glioblastoma, David M. Anson, Samson Amos, Robert L. Paris, Denise S. Simpson

Robert L. Paris, Ph.D.

Glioblastoma multiforme (GBM) is widely recognized as the most common and lethal of the malignant gliomas. Few effective therapeutic treatments are available as five-year survival rates of diagnosed individuals are less than five percent. Luteolin, a common flavonoid found in a variety of fruits and vegetables, has demonstrated significant promise in combating cancers of the breast, colon, liver, lung, and bone. In this study, we investigated the effects of luteolin on glioblastoma multiforme cell lines U-251, U-87, and U-1242. Cell viability was assessed using cell count with trypan blue exclusion and MTT assays. Results revealed that luteolin reduces GBM cell ...


Guillain-Barre Syndrome, Tyler B. Skelton 2016 Otterbein University

Guillain-Barre Syndrome, Tyler B. Skelton

Master of Science in Nursing (MSN) Student Scholarship

Guillain-Barre Syndrome consists of a group of neuropathic conditions characterized by progressive weakness and diminished or absent myotatic reflexes. The estimated annual incidence in the United States is 1.65 to1.79 per 100,000 persons (Walling & Dickson, 2013). Understanding how this condition progresses and the affects it has on a patient will assistant in providing optimal patient care as a future nurse anesthetist. As stated by Turakhia, P., Barrick, B., and Berman, J. (2013) “the anesthetic implications for the various comorbidities are varied and can be profound” (p.1). An individual who suffers from Guillain-Barre is a patient who ...


Glial Cell Involvement In Early Alzheimer's Disease, Rachel Y. De La Torre 2016 Portland State University

Glial Cell Involvement In Early Alzheimer's Disease, Rachel Y. De La Torre

PSU McNair Scholars Online Journal

Glial cells, the resident immune cells of the brain, are important for brain health as they represent a critical function both in brain injury as well as in brain development and maintenance. Following brain injury, glia quickly respond by cleaning up neuronal and synaptic debris. In addition to their role as the cleaning cell of the brain, recent research has shown that during development, glia also shape and fine-tune neural connections by eliminating weak synapses fated for removal. However, whether glial cells also continue to remodel synaptic architecture in the adult brain is unclear. Moreover, synaptic pruning and loss are ...

Neurology Publications and Presentations

The multicenter phase III preclinical trial concept is currently discussed to enhance the predictive value of preclinical stroke research. After public announcement, we collected a community feedback on the concept with emphasis on potential design features and guidelines by an anonymous survey. Response analysis was conducted after plausibility checks by applying qualitative and quantitative measures. Most respondents supported the concept, including the implementation of a centralized steering committee. Based on received feedback, we suggest careful, stepwise implementation and to leave selected competencies and endpoint analysis at the discretion of participating centers. Strict application of quality assurance methods is accepted, but ...

Based on the 7-year experience of the Italian Clinical Network for FSHD, we revised the FSHD clinical form to describe, in a harmonized manner, the phenotypic spectrum observed in FSHD. The new Comprehensive Clinical Evaluation Form (CCEF) defines various clinical categories by the combination of different features. The inter-rater reproducibility of the CCEF was assessed between two examiners using kappa statistics by evaluating 56 subjects carrying the molecular marker used for FSHD diagnosis. The CCEF classifies: (1) subjects presenting facial and scapular girdle muscle weakness typical of FSHD (category A, subcategories A1-A3), (2) subjects with muscle weakness limited to scapular ...


Activation Of Target Gene Expression In Neurons By The C. Elegans Rfx Transcription Factor, Daf-19, Katherine P. Mueller 2016 Lawrence University

Activation Of Target Gene Expression In Neurons By The C. Elegans Rfx Transcription Factor, Daf-19, Katherine P. Mueller

Lawrence University Honors Projects

DAF-19, the only RFX transcription factor found in C. elegans, is required for the formation of neuronal sensory cilia. Four isoforms of the DAF-19 protein have been reported, and the m86 nonsense (null) mutation affecting all four isoforms has been shown to prevent cilia formation. Transcriptome analyses employing microarrays of L1 and adult stage worms were completed using RNA from daf-19(m86) worms and an isogenic wild type strain to identify additional putative DAF-19 target genes. Using transcriptional fusions with GFP, we compared the expression patterns of several potential gene targets using fluorescence confocal microscopy. Expression patterns were characterized in ...


Newer Oral Anticoagulants: Stroke Prevention And Pitfalls, Anand Patel, Richard P. Goddeau, Nils Henninger 2016 University of Massachusetts Medical School

Newer Oral Anticoagulants: Stroke Prevention And Pitfalls, Anand Patel, Richard P. Goddeau, Nils Henninger

Open Access Articles

Warfarin is very effective in preventing stroke in patients with atrial fibrillation. However, its use is limited due to fear of hemorrhagic complications, unpredictable anticoagulant effects related to multiple drug interactions and dietary restrictions, a narrow therapeutic window, frequent difficulty maintaining the anticoagulant effect within a narrow therapeutic window, and the need for inconvenient monitoring. Several newer oral anticoagulants have been approved for primary and secondary prevention of stroke in patients with non-valvular atrial fibrillation. These agents have several advantages relative to warfarin therapy. As a group, these direct oral anticoagulants (DOAC), which include the direct thrombin inhibitor, dabigatran, and ...

Theoretical And Experimental Analysis Of The Antioxidant And Anti-Amyloid Features Of Synthetic Resveratrol Mimics, William Horton, Anne Kokel, Fanni Török, Chris Tran, Marianna Török, Bela Török

UMass Center for Clinical and Translational Science Research Retreat

Diaryl hydrazones, possessing similar structure to the popular red wine antioxidant resveratrol, have been previously identified as multitarget compounds interfering with several processes associated with the pathogenesis of Alzheimer’s disease (AD). These compounds exhibited particularly strong inhibition of the amyloid beta (A) peptide self-assembly, including blocking the formation of fibrils and oligomers, species that are widely accepted to be neurotoxic. The molecules were also powerful free radical scavengers and thus have a potential to defend against oxidative stress.

In order to learn more about the mode of action of the compounds, theoretical and experimental studies have been carried out ...

Faculty of Health Sciences & Medicine Publications

Multiple sclerosis (MS) is an autoimmune disease characterised by lymphocytic infiltration of the central nervous system and subsequent destruction of myelin and axons. On the background of a genetic predisposition to autoimmunity, environmental triggers are assumed to initiate the disease. The majority of MS research has focused on the pathological involvement of lymphocytes and other immune cells, yet a paucity of attention has been given to erythrocytes, which may play an important role in MS pathology. The following review briefly summarises how erythrocytes may contribute to MS pathology through impaired antioxidant capacity and altered haemorheological features. The effect of disease-modifying ...


An Initial Analysis Of A Long-Term Ketogenic Diet’S Impact On Motor Behavior, Brain Purine Systems, And Nigral Dopamine Neurons In A New Genetic Rodent Model Of Parkinson’S Disease, Jacob Rubin, William H. Church 2016 Trinity College

An Initial Analysis Of A Long-Term Ketogenic Diet’S Impact On Motor Behavior, Brain Purine Systems, And Nigral Dopamine Neurons In A New Genetic Rodent Model Of Parkinson’S Disease, Jacob Rubin, William H. Church

Senior Theses and Projects

A growing body of research suggests that dopaminergic cell death seen in Parkinson’s disease is caused by mitochondrial dysfunction. Oxidative stress, with subsequent generation of reactive oxygen species, is the hallmark biochemical product of mitochondrial dysfunction. The ketogenic diet has been found to enhance mitochondrial energy production, protect against reactive oxygen species-generated cell death, and increase adenosine, a purine that modulates dopamine activity. The current study evaluates the effects of a long-term (5-month) ketogenic diet on behavioral, neurochemical, and neuroanatomical measures in PINK1-KO rats, a new animal model of Parkinson’s disease. Both wild-type and PINK1-KO animals fed a ...


Expression And Function Of Inflammation-Associated Micrornas In Traumatic Brain Injury, Emily Harrison 2016 University of Nebraska Medical Center

Expression And Function Of Inflammation-Associated Micrornas In Traumatic Brain Injury, Emily Harrison

Theses & Dissertations

MicroRNAs (miRNAs) are important regulators of gene expression. Many neurological diseases, including traumatic brain injury alter expression of miRNAs in the brain. However, the function of these molecules in the context of TBI is largely unknown. Here we report multiple potential roles for miRNAs in TBI, some of which extend beyond the traditional model of post-transcriptional regulation, highlighting that these RNA molecules may have broader implications for the neurobiology of disease. We found that miR-155 plays an essential role in interferon expression after CCI and that miR-155 contributes to TBI induced anxiety, potentially through regulation of interferons. Expression of miR-155 ...


Clinical And Demographic Variables Associated With Cognitive Deficits, Symptom Severity, And Duration After Concussive Injury In Adolescents: A Retrospective Study, Seema S. Aggarwal 2016 Texas Medical Center Library

Clinical And Demographic Variables Associated With Cognitive Deficits, Symptom Severity, And Duration After Concussive Injury In Adolescents: A Retrospective Study, Seema S. Aggarwal

UT SON Dissertations (Open Access)

Background: Concussions in adolescents are a public health concern with the growing popularity of high school sports. Recent legislation mandates that athletes who are suspected of a concussion be cleared to return-to-play by a clinician. More research is needed to develop a concussion predictive model to identify populations at risk for more severe and prolonged symptoms and long-term neurologic deficits.

Aims: The aims of this study were to (1) examine the effect of race and gender on neurocognitive and symptom scores and (2) determine which clinical (e.g., number of concussions, migraine history, learning disabilities/ attention deficit disorders) and demographic ...


Antibodies To Heterogenous Nuclear Ribonucleoprotein A1 Penetrate Neurons Leading To Multiple Downstream Effects Resulting In Neurodegeneration, Joshua Nathan Douglas 2016 University of Tennessee Health Science Center

Antibodies To Heterogenous Nuclear Ribonucleoprotein A1 Penetrate Neurons Leading To Multiple Downstream Effects Resulting In Neurodegeneration, Joshua Nathan Douglas

Theses and Dissertations (ETD)

Multiple sclerosis (MS) is the most common demyelinating disorder of the central nervous system. MS is believed to occur in genetically susceptible individuals due to an unknown environmental stimulus. MS patients produce autoantibodies to heterogenous nuclear ribonuclearprotein A1 (hnRNP A1), an RNA binding protein (RBP) highly expressed in neurons. hnRNP A1 functions in pre-mRNA splicing, mRNA trafficking, and translation. Furthermore, the anti-hnRNP A1 antibodies are specific to a N-terminal region termed ‘M9’ which serves as a nuclear export sequence/nuclear localization sequence (NES/NLS) responsible for nuclear/cytoplasmic transport of the protein. In this manuscript we will provide data revealing ...

Exploring The Effect Of Novel Small Molecules On Oligodendrocyte Precursor Proliferation, Sagune Sakya

University Scholar Projects

Gliomas, a type of brain tumor, can be difficult to treat and have a poor survival rate. One pathway that leads to glioma formation is excessive signaling by platelet derived growth factors (PDGF) through PDGF receptor α (PDGFRα). Through this research, I found that novel compounds that downregulate PDGFRα decrease proliferation of Oli-neu cells, an oligodendrocyte precursor cell model, and identified signaling pathways through which these compounds may exert their effect. Further investigation may identify targets for development of glioma treatments.
