Stroke Rehabilitation, Length-Of-Stay, And Re-Admission Rates: A Literature Review, Morgen Hagedorn

All Graduate Theses, Dissertations, and Other Capstone Projects

Stroke is shown to be a significant U.S. health problem with a profound impact on the nation’s rising healthcare costs (Hall, Levant, & DeFrances, 2012). Longer patient length-of-stay [LOS] and higher re-admission rates have brought consequences to healthcare systems as institutional budgets are unable to reconcile the additional services and the influx of healthcare demands. Through a comprehensive literature review, the author illustrates the general knowledge available on the stroke experience, on stroke care and rehabilitation, and on patient LOS and re-admission rates. The literature review is based on general medical research with a focus on the stroke population. The …

Orphan Nuclear Receptor Nur77 Regulates Androgen Receptor Gene Expression In Mouse Ovary., Anyi Dai, Guijun Yan, Qinyuan He, Yue Jiang, Qun Zhang, Ting Fang, Lijun Ding, Jianxin Sun, Haixiang Sun, Yali Hu

Center for Translational Medicine Faculty Papers

The androgen receptor (AR) is a nuclear receptor that is expressed in growing follicles and involved in folliculogenesis and follicle growth. The orphan nuclear receptor, Nur77, also has an important role in steroid signaling and follicle maturation. We hypothesized that AR levels and androgen signaling through AR are regulated by Nur77 in the ovary. In the ovaries of Nur77 knockout mice (n = 5), real-time PCR results showed that the mRNA levels of AR and an androgen signaling target gene, Kitl, were decreased by 35% and 24%, respectively, relative to wild-type mice (n = 5), which suggested transcriptional regulation of …

Microrna-145 Protects Cardiomyocytes Against Hydrogen Peroxide (H₂O₂)-Induced Apoptosis Through Targeting The Mitochondria Apoptotic Pathway., Ruotian Li, Guijun Yan, Qiaoling Li, Haixiang Sun, Yali Hu, Jianxin Sun, Biao Xu

Center for Translational Medicine Faculty Papers

MicroRNAs, a class of small and non-encoding RNAs that transcriptionally or post-transcriptionally modulate the expression of their target genes, has been implicated as critical regulatory molecules in many cardiovascular diseases, including ischemia/reperfusion induced cardiac injury. Here, we report microRNA-145, a tumor suppressor miRNA, can protect cardiomyocytes from hydrogen peroxide H₂O₂-induced apoptosis through targeting the mitochondrial pathway. Quantitative real-time PCR (qPCR) demonstrated that the expression of miR-145 in either ischemia/reperfused mice myocardial tissues or H₂O₂-treated neonatal rat ventricle myocytes (NRVMs) was markedly down-regulated. Over-expression of miR-145 significantly inhibited the H₂O₂-induced cellular apoptosis, ROS production, mitochondrial structure disruption as well as the …

Ethanol Interactions With Dl-Methylphenidate Versus D-Methylphenidate In Humans, Owen Reeves

MUSC Theses and Dissertations

Adult Attention-Deficit/Hyperactivity Disorder (ADHD) affects~ 4.4% of the adult population, and patients with this disorder frequently have comorbid substance abuse disorders. Methylphenidate (MPH) is considered a first line pharmacotherapy agent in the treatment of ADHD, and is commonly used or co-abused with alcohol. Hydrolysis of oral racemic methylphenidate (dl-MPH) by carboxylesterase 1 (CES1) limits the bioavailability of the pharmacologically active d-MPH isomer to approximately 30% and that of the inactive 1-MPH isomer to only 1-2%. Co-administration of dl-MPH with ethanol results in elevated d-MPH plasma concentrations, as well as CES1 mediated enantioselective transesterification of 1-MPH to 1-ethylphenidate (EPH). The present …

Development Of A Bi-Directional Electronics Platform For Advanced Neural Applications, Luca Abbati

USF Tampa Graduate Theses and Dissertations

This work presents a high-voltage, high-precision bi-directional multi-channel system capable of stimulating neural activity through bi-phasic pulses of amplitude up to ∓50 V while recording very low-voltage responses as low as tens of microvolts. Most of the systems reported from the scientific community possess at least one of the following common limitations: low stimulation voltages, low gain capabilities, or insufficient bandwidth to acquire a wide range of different neural activities.

While systems can be found that present remarkable capabilities in one or more specific areas, a versatile system that performs over all these aspects is missing. Moreover, as many novel …

Targeting The Endocannabinoid System To Reduce Inflammatory Pain, Sudeshna Ghosh

Theses and Dissertations

The endogenous cannabinoids (endocannabinoids) anandamide (AEA) and 2-arachidonylglycerol (2-AG) exert their effects predominantly through cannabinoid CB1 and CB2 receptors, but these actions are short-lived because of rapid hydrolysis by fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), respectively. Selective inhibition of either enzyme elevates CNS levels of the appropriate endocannabinoid and produces analgesic effects with fewer psychomimetic side effects than Δ9-tetrahydrocannabinol (THC), the primary active constituent of marijuana. While cannabinoid receptor agonists and FAAH inhibitors reliably produce anti-inflammatory and anti-hyperalgesic effects in the carrageenan test and other inflammatory pain models, much less is known about the consequences of inhibiting …

Artemis And Metnase Mediated Processing Of 3΄-Blocked Dna Lesions: Role In Radio/Chemoresistance And Dna Repair, Susovan Mohapatra

Theses and Dissertations

DNA double-strand breaks (DSB) with chemically modified end-termini are the most significant lesions resulting from radio/chemotherapeutic intervention of cancer and non homologous end-joining (NHEJ) factor Artemis nuclease has been implicated in the repair of such breaks. To examine whether the resolution of terminally blocked DNA DSBs is the biologically relevant function of Artemis, Artemis deficient fibroblasts were stably complemented with wild type or an endonuclease deficient D165N mutant Artemis. Physiological levels of wild type (WT) Artemis completely restored DSB repair proficiency and resistance to γ-radiation, bleomycin, and neocarzinostatin. Cells expressing the D165N mutants remained as chemo/radiosensitive and as repair deficient …

Higher Il-6 And Il6:Igf Ratio In Patients With Barth Syndrome, Lori D. Wilson, Sadeeka Al-Majid, Cyril Rakovski, Christina D. Schwindt

Mathematics, Physics, and Computer Science Faculty Articles and Research

Background: Barth Syndrome (BTHS) is a serious X-linked genetic disorder associated with mutations in the tafazzin gene (TAZ, also called G4.5). The multi-system disorder is primarily characterized by the following pathologies: cardiac and skeletal myopathies, neutropenia, growth delay, and exercise intolerance. Although growth anomalies have been widely reported in BTHS, there is a paucity of research on the role of inflammation and the potential link to alterations in growth factors levels in BTHS patients.

Methods: Plasma from 36 subjects, 22 patients with Barth Syndrome (0.5 - 24 yrs) and 14 healthy control males (8 - 21 yrs) was …

Research outputs 2012

Advancing age is associated with cardiovascular disease, diabetes mellitus and cancer, and shows significant inter-individual variability. To identify ageing-related biomarkers we performed a proteomic analysis on 1890 Chinese Han individuals, 1136 males and 754 females, aged 18 to 82 years, using weak cation exchange magnetic bead based MALDI-TOF-MS analysis. The study identified 44 peptides which varied in concentration in different age groups. In particular, apolipoprotein A-I (ApoA1) concentration gradually increased between 18 to 50 years of age, the levels of fibrinogen alpha (FGA) decreased over the same age span, while albumin (ALB) was significantly degraded in middle-aged individuals. In addition, …

Communication Disorders Faculty Publications

Velo-cardio-facial syndrome/DiGeorge syndrome, also known as 22q11.2 deletion syndrome (22q11DS) is the most common microdeletion syndrome, with an estimated incidence of 1/2,000 – 1/4,000 live births. Approximately 9–11% of patients with this disorder have an overt cleft palate (CP), but the genetic factors responsible for CP in the 22q11DS subset are unknown. The TBX1 gene, a member of the T-box transcription factor gene family, lies within the 22q11.2 region that is hemizygous in patients with 22q11DS. Inactivation of one allele of Tbx1 in the mouse does not result in CP, but inactivation of both alleles does. Based on these data, …

Msh2 Acts In Medium-Spiny Striatal Neurons As An Enhancer Of Cag Instability And Mutant Huntingtin Phenotypes In Huntington's Disease Knock-In Mice., Marina Kovalenko, Ella Dragileva, Jason St Claire, Tammy Gillis, Jolene R Guide, Jaclyn New, Hualing Dong, Raju Kucherlapati, Melanie H Kucherlapati, Michelle E Ehrlich, Jong-Min Lee, Vanessa C Wheeler

Farber Institute for Neuroscience Faculty Papers

The CAG trinucleotide repeat mutation in the Huntington's disease gene (HTT) exhibits age-dependent tissue-specific expansion that correlates with disease onset in patients, implicating somatic expansion as a disease modifier and potential therapeutic target. Somatic HTT CAG expansion is critically dependent on proteins in the mismatch repair (MMR) pathway. To gain further insight into mechanisms of somatic expansion and the relationship of somatic expansion to the disease process in selectively vulnerable MSNs we have crossed HTT CAG knock-in mice (HdhQ111) with mice carrying a conditional (floxed) Msh2 allele and D9-Cre transgenic mice, in which Cre recombinase is expressed specifically in MSNs …

Sugar Consumption And Cognitive Aging In The Swedish Adoption/Twin Study Of Aging, Shyam Seetharaman

USF Tampa Graduate Theses and Dissertations

Abstract

Consumption of foods high in sugar content has been linked with the development of metabolic abnormalities such as cardiovascular disease and type II diabetes, major sources of global health concerns. Although the detrimental consequences of high intake of sugar on abnormal metabolic processes are established, it is not known how this association affects (or accelerates) cognitive aging.

The current project was based on data from the Swedish Adoption/Twin Study of Aging (SATSA) to test the hypothesis that high refined sugar intake contributes to accelerated trajectories of cognitive decline assessed longitudinally. Trajectories of cognitive change were assessed as a function …

Behavioral And Immunological Phenotypes Of Transgenic Mice Overexpressing Human Secreted Amyloid Precursor Protein Alpha: Implications For Autism, Antoinette R. Bailey

USF Tampa Graduate Theses and Dissertations

Autism is a heterogeneous neurodevelopmental disorder that is characterized by impaired social interaction and communication as well as restricted and repetitive behaviors and focused interests. In addition to the cardinal behavioral characteristics observed for diagnosis, autistic individuals exhibit a number of comorbid conditions as well as a variety of aberrant immunological features. Recent studies report that plasma from autistic children contained elevated levels of secreted amyloid precursor protein alpha (sAPP-á), the á-secretase cleavage product of the amyloid precursor protein (APP) which is ubiquitously expressed in the brain, spleen, thymus and other organs. Interestingly, the sAPP-á fragment functions as a neurotrophic …

Efficacy Of Increased Ube3a Protein Levels In The Brain In Rescuing The Phenotype Of An Angelman Syndrome Mouse, Jennifer L. Daily

USF Tampa Graduate Theses and Dissertations

Angelman syndrome (AS), a genetic disorder occurring in approximately one in every 15,000 births, is characterized by severe mental retardation, seizures, difficulty speaking and ataxia. The gene responsible for AS was discovered to be UBE3A and encodes an E6-AP ubiquitin ligase. A unique feature of this gene is that it undergoes maternal imprinting in a neuron-specific manner. In the majority of AS cases, there is a mutation or deletion in the maternally inherited UBE3A gene, although other cases are the result of uniparental disomy or mismethylation of the maternal gene. While most human disorders characterized by severe mental retardation involve …

The Formin Fmnl3 Is A Cytoskeletal Regulator Of Angiogenesis, Clare Hetheridge, Alice N. Scott, Rajeeb K. Swain, John W. Copeland, Henry N. Higgs

Dartmouth Scholarship

The process of angiogenesis requires endothelial cells (ECs) to undergo profound changes in shape and polarity. Although this must involve remodelling of the EC cytoskeleton, little is known about this process or the proteins that control it. We used a co-culture assay of angiogenesis to examine the cytoskeleton of ECs actively undergoing angiogenic morphogenesis. We found that elongation of ECs during angiogenesis is accompanied by stabilisation of microtubules and their alignment into parallel arrays directed at the growing tip. In other systems, similar microtubule alignments are mediated by the formin family of cytoskeletal regulators. We screened a library of human …

Genetically Modified T-Cells Expressing Chimeric Antigen Receptors In The Treatment Of Cancer, Efrat Bruck

The Science Journal of the Lander College of Arts and Sciences

Dr. Carl June and his colleagues at the University of Pennsylvania have succeeded in treating patients with Chronic Lymphocytic Leukemia using gene therapy. Two of the three patients treated sustained a complete remission and one a partial remission. The procedure involved transducing the patients’ T cells to express chimeric antigen receptors which target a particular protein found on both healthy and cancerous B cells. Following infusion of the newly transduced T cells, each patient developed clinical symptoms associated with an intense immune response. Shortly thereafter, tumors were completely eliminated in two of the patients and partially eliminated in the third. …

Epigenetics: A Possible Mechanism Of Memory, Aliza Grossman Rubenstein

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction to this article: The mind-body connection has fascinated philosophers and scientists for centuries. How is it possible that consciousness arises from a lump of matter known as the brain? How does neurons’ firing affect choice and beliefs? How do the electrochemical properties of the brain allow for the memory of events long after they’ve occurred? One of the most studied of these areas is that of memory. Researchers seek to understand the biological basis behind memory and how that biology is affected in individuals suffering from memory disorders.

Modified-Release Drugs, Chedva Farkas

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction to this article: Ever since the discovery of bacteria and their role in the disease process in the mid-1800s, scientists have been heavily involved in the discovery and development of drug therapies and their mechanism of action in the human body. Shortly after the initial discovery came the era of drug discovery of the late 1800s-early 1900s, also known as the “drug revolution” (Dash and Cudworth 1998). Although the drug revolution led to the rapid discovery of many new drugs, pharmacological factors such as dosage forms, drug delivery systems, plasma drug levels, …

Understanding The Gender-Based Mechanism Of Mso In Als Mice: A Metabolic Characterization Of The Sod1-G93a Mouse Model, Monica Ann Bame

Wayne State University Dissertations

Amyotrophic Lateral Sclerosis (ALS) is a devastating neurodegenerative disease characterized by motor neuron death and a corresponding loss of neuromuscular connections resulting in muscle atrophy. Patients become paralyzed shortly after symptom onset and typically die within one to five years of pulmonary complications. ALS is a relatively rare disease, with an overall incidence of approximately 2 in 100,000 people per year and a prevalence of about 5 in 100,000 people. It is typically associated with increasing age and has a slight male prevalence, with a male to female ratio of approximately 3:2. ALS is classified as either familial (the less …

Predicting Vision Loss In Healthy Aging With Manganese-Enhanced Mri Of The Rat Eye, David Bissig

Wayne State University Dissertations

In healthy aging, visual function declines throughout adulthood. Age-related changes in neuronal ion homeostasis -- specifically, increased Ca2+ influx through L-type voltage gated calcium channels (L-VGCCs) -- are believed to contribute to certain functional declines, but this possibility has not yet been tested in the neural retina. In young, mid- and old adult Long-Evans rats, we compared visual function (optokinetic tracking), as well as retinal physiology and eye morphology (Mn2+-enhanced MRI (MEMRI), which uses neuronal Mn2+ uptake as a marker of Ca2+ influx). We documented significant age-related decreases in visual performance and increases in retinal ion influx. We confirmed that …

Mir-145 Directly Targets P70s6k1 In Cancer Cells To Inhibit Tumor Growth And Angiogenesis., Qing Xu, Ling-Zhi Liu, Xu Qian, Qi Chen, Yue Jiang, Dan Li, Lihui Lai, Bing-Hua Jiang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

MiR-145 can regulate cell apoptosis, proliferation, neural development and stem cell differentiation. Previous studies indicate that miR-145 is downregulated in human colon cancer cells. However, the molecular mechanisms of miR-145 used to regulate colon carcinogenesis and angiogenesis remain to be clarified. Here, we show that the expression of miR-145 is downregulated in colon and ovarian cancer tissues and cell lines. MiR-145 inhibits p70S6K1 post-transcriptional expression by binding to its 3'-UTR. The angiogenic factors hypoxia-inducible factor 1 (HIF-1) and vascular endothelial growth factor (VEGF), which are downstream molecules of p70S6K1, are decreased by miR-145 overexpression. P70S6K1 rescues miR-145-suppressed HIF-1 and VEGF …

The Dermatan Sulfate Proteoglycan Decorin Modulates Α2Β1 Integrin And The Vimentin Intermediate Filament System During Collagen Synthesis., Oliver Jungmann, Katerina Nikolovska, Christian Stock, Jan-Niklas Schulz, Beate Eckes, Christoph Riethmüller, Rick T Owens, Renato V Iozzo, Daniela G Seidler

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Decorin, a small leucine-rich proteoglycan harboring a dermatan sulfate chain at its N-terminus, is involved in regulating matrix organization and cell signaling. Loss of the dermatan sulfate of decorin leads to an Ehlers-Danlos syndrome characterized by delayed wound healing. Decorin-null (Dcn(-/-)) mice display a phenotype similar to that of EDS patients. The fibrillar collagen phenotype of Dcn(-/-) mice could be rescued in vitro by decorin but not with decorin lacking the glycosaminoglycan chain. We utilized a 3D cell culture model to investigate the impact of the altered extracellular matrix on Dcn(-/-) fibroblasts. Using 2D gel electrophoresis followed by mass spectrometry, …

Limitations Of The Rhesus Macaque Draft Genome Assembly And Annotation, Xiongfei Zhang, Joel Goodsell, Robert B. Norgren

Journal Articles: Genetics, Cell Biology & Anatomy

Finished genome sequences and assemblies are available for only a few vertebrates. Thus, investigators studying many species must rely on draft genomes. Using the rhesus macaque as an example, we document the effects of sequencing errors, gaps in sequence and misassemblies on one automated gene model pipeline, Gnomon. The combination of draft genome with automated gene finding software can result in spurious sequences. We estimate that approximately 50% of the rhesus gene models are missing, incomplete or incorrect. The problems identified in this work likely apply to all draft vertebrate genomes annotated with any automated gene model pipeline and thus …
