Intranasal Oxytocin Enhances Connectivity In The Neural Circuitry Supporting Social Motivation And Social Perception In Children With Autism., Ilanit Gordon, Allison Jack, Charlotte M Pretzsch, Brent Vander Wyk, James F Leckman, Ruth Feldman, Kevin A. Pelphrey
Pharmacology and Physiology Faculty Publications
Oxytocin (OT) has become a focus in investigations of autism spectrum disorder (ASD). The social deficits that characterize ASD may relate to reduced connectivity between brain sites on the mesolimbic reward pathway (nucleus accumbens; amygdala) that receive OT projections and contribute to social motivation, and cortical sites involved in social perception. Using functional magnetic resonance imaging and a randomized, double blind, placebo-controlled crossover design, we show that OT administration in ASD increases activity in brain regions important for perceiving social-emotional information. Further, OT enhances connectivity between nodes of the brain's reward and socioemotional processing systems, and does so preferentially ...
The Effect Of Luteolin On Human Glioblastoma, 2016 Cedarville University
The Effect Of Luteolin On Human Glioblastoma, David M. Anson, Samson Amos, Robert L. Paris, Denise S. Simpson
Samson Amos, R.Ph., 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 ...

Spinal Cord Injury And Autonomic Dysreflexia- A Case Report, 2016 University of Missouri-Kansas City School of Medicine
Spinal Cord Injury And Autonomic Dysreflexia- A Case Report, Apurva Bhatt, Brit Moore, Talal Asif, Kristy E. Steigerwalt, Rebecca R. Pauly
Marshall Journal of Medicine
Autonomic dysreflexia (AD) is a life threatening condition affecting patients with spinal cord lesions T6 level and above. A 51 year old male with a history of paraplegia due to a C6 spinal cord injury (30 years prior) presented with recurrent debilitating episodic diaphoresis, hypertension, low body temperature, and bradycardia. Previous hospitalizations presumed sepsis from UTI to be the etiology, however on further evaluation his symptoms were consistent with undiagnosed AD. This article describes a unique case presentation and reviews AD in depth, including the etiology, pathophysiology and management.

Journal of Mind and Medical Sciences
As a 5-α reductase inhibitor, Finasteride has proven effective in ameliorating two conditions documented to be androgen dependent, namely male androgenic alopecia and benign prostatic hyperplasia. Therapeutic results are maintained as long as the drug is administered, with treatment cessation generally leading to the return of symptomatology for each condition. In addition, during the therapeutic phase, several adverse effects have been reported, some of which persist long or indefinitely after treatment cessation, known as “post-finasteride syndrome.”
Herein we present and discuss the most common finasteride side effects, along with a psycho-neuroendocrine rationale that could explain the persistence of many adverse ...

Cell and Developmental Biology Publications and Presentations
Key challenges faced by all cells include how to spatiotemporally organize complex biochemistry and how to respond to environmental fluctuations. The budding yeast Saccharomyces cerevisiae harnesses alternative protein folding mediated by yeast prion domains (PrDs) for rapid evolution of new traits in response to environmental stress. Increasingly, it is appreciated that low complexity domains similar in amino acid composition to yeast PrDs (prion-like domains; PrLDs) found in metazoa have a prominent role in subcellular cytoplasmic organization, especially in relation to RNA homeostasis. In this review, we highlight recent advances in our understanding of the role of prions in enabling rapid ...

B Cells Populating The Multiple Sclerosis Brain Mature In The Draining Cervical Lymph Nodes, J. N. Stern, G. Yaari, J. A. Vander Heiden, G. Church, W. F. Donahue, R. Q. Hintzen, A. J. Huttner, J. D. Laman, R. M. Nagra, K. C. O’Connor
Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS) characterized by autoimmune-mediated demyelination and neurodegeneration. The CNS of patients with MS harbors expanded clones of antigen-experienced B cells that reside in distinct compartments including the meninges, cerebrospinal fluid (CSF), and parenchyma. It is not understood whether this immune infiltrate initiates its development in the CNS or in peripheral tissues. B cells in the CSF can exchange with those in peripheral blood, implying that CNS B cells may have access to lymphoid tissue that may be the specific compartment(s) in which CNS-resident B cells encounter antigen ...

In recent years, there has been increasing interest in the potential for alterations to the brain's resting-state networks (RSNs) to explain various kinds of psychopathology. RSNs provide an intriguing new explanatory framework for hallucinations, which can occur in different modalities and population groups, but which remain poorly understood. This collaboration from the International Consortium on Hallucination Research (ICHR) reports on the evidence linking resting-state alterations to auditory hallucinations (AH) and provides a critical appraisal of the methodological approaches used in this area. In the report, we describe findings from resting connectivity fMRI in AH (in schizophrenia and nonclinical individuals ...
Is Online Motor Control Really Impaired In Parkinson's Disease?, 2016 The University of Western Ontario
Is Online Motor Control Really Impaired In Parkinson's Disease?, Kate E. Merritt
Electronic Thesis and Dissertation Repository
Patients with Parkinson’s disease (PD) are thought to be selectively impaired in consciously-mediated online automatic motor control, whereas the ability to perform subconscious online adjustments remains intact. This present study evaluates the hypothesis that the previously alleged deficits in online motor control in PD are not due to the consciousness of the correction, but rather are attributable to aspects of the prior experimental designs disproportionately penalizing patients for PD-related bradykinesia. Here, we implemented a modified traditional double-step paradigm to investigate consciously-mediated online motor control in PD, in a manner that would be unconfounded by disease-related bradykinesia. Further, we investigated ...
Dyslexia And Language Impairment Associated Genetic Markers Influence Cortical Thickness And White Matter In Typically Developing Children, John D. Eicher, Jean A. Frazier, David N. Kennedy, Jeffrey R. Gruen
Jean A. Frazier
Dyslexia and language impairment (LI) are complex traits with substantial genetic components. We recently completed an association scan of the DYX2 locus, where we observed associations of markers in DCDC2, KIAA0319, ACOT13, and FAM65B with reading-, language-, and IQ-related traits. Additionally, the effects of reading-associated DYX3 markers were recently characterized using structural neuroimaging techniques. Here, we assessed the neuroimaging implications of associated DYX2 and DYX3 markers, using cortical volume, cortical thickness, and fractional anisotropy. To accomplish this, we examined eight DYX2 and three DYX3 markers in 332 subjects in the Pediatrics Imaging Neurocognition Genetics study. Imaging-genetic associations were examined by ...

Characterization And Personalization Of Botulinum Toxin Type A Therapy For Upper Limb Tremor In Parkinson Disease And Essential Tremor Patients Using Multi-Sensor Kinematic Technology, Olivia Samotus
Electronic Thesis and Dissertation Repository
Tremor commonly affects the upper extremities in essential tremor (ET) and Parkinson disease (PD) patients where many experience functional disability and ultimately seek therapy. As ET and PD tremor features overlap and clinical assessment is challenging due to its highly complex nature, misdiagnosis is common resulting in unsuitable therapies and prognosis. Current treatment options for ET and PD tremor include pharmacotherapy, focal therapy with botulinum toxin type A (BoNT-A) injections, and surgical interventions which provide modest relief of tremor. However, such therapies are commonly associated with significant adverse events and lack long-term efficacy and tolerability. Hence lack of standardized, objective ...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease; survival in ALS is typically 3-5 years. No treatment extends patient survival by more than three months. Approximately 20% of familial ALS and 1-3% of sporadic ALS patients carry a mutation in the gene encoding superoxide dismutase 1 (SOD1). In a transgenic ALS mouse model expressing the mutant SOD1(G93A) protein, silencing the SOD1 gene prolongs survival. One study reports a therapeutic effect of silencing the SOD1 gene in systemically treated adult ALS mice; this was achieved with a short hairpin RNA, a silencing molecule that has raised multiple safety concerns ...

Derepression of DUX4 in skeletal muscle has emerged as a likely cause of pathology in facioscapulohumeral muscular dystrophy (FSHD). Here we report on the use of antisense phosphorodiamidate morpholino oligonucleotides to suppress DUX4 expression and function in FSHD myotubes and xenografts. The most effective was phosphorodiamidate morpholino oligonucleotide FM10, which targets the polyadenylation signal of DUX4. FM10 had no significant cell toxicity, and RNA-seq analyses of FSHD and control myotubes revealed that FM10 down-regulated many transcriptional targets of DUX4, without overt off-target effects. Electroporation of FM10 into FSHD patient muscle xenografts in mice also down-regulated DUX4 and DUX4 targets. These ...
Guillain-Barre Syndrome, 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, 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 ...
Phase Iii Preclinical Trials In Translational Stroke Research: Community Response On Framework And Guidelines, Johannes Boltze, Daniel-Christoph Wagner, Nils Henninger, Nikolaus Plesnila, Cenk Ayata
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 ...
