The purpose of this multicenter, prospective, randomized, placebo-controlled study was to evaluate and compare the efficacy of two cognitive rehabilitation interventions (Memory and Attention Adaptation Training (MAAT) and Attention Builders Training (ABT)), with and without pharmacologic enhancement (i.e., with methylphenidate (MPH) or placebo), for treating persistent cognitive problems after traumatic brain injury (TBI). Adults with a history of TBI at least four months prior to study enrollment with either objective cognitive deficits or subjective cognitive complaints were randomized to receive MPH or placebo and MAAT or ABT, yielding four treatment combinations: MAAT/MPH (N=17), ABT/MPH (N=19), MAAT/placebo (N=17), and ABT/placebo (N=18). …

Self-Complementary Adeno-Associated Virus Vectors Improve Transduction Efficiency Of Corneal Endothelial Cells, Anja K. Gruenert, Marta Czugala, Christian Mueller, Marco Schmeer, Martin Schleef, Friedrich E. Kruse, Thomas A. Fuchsluger

Christian Mueller

Transplantation of a donor cornea to restore vision is the most frequently performed transplantation in the world. Corneal endothelial cells (CEC) are crucial for the outcome of a graft as they maintain corneal transparency and avoid graft failure due to corneal opaqueness. Given the characteristic of being a monolayer and in direct contact with culture medium during cultivation in eye banks, CEC are specifically suitable for gene therapeutic approaches prior to transplantation. Recombinant adeno-associated virus 2 (rAAV2) vectors represent a promising tool for gene therapy of CEC. However, high vector titers are needed to achieve sufficient gene expression. One of …

A Murine Model Of Inflammation-Induced Cerebral Microbleeds, Rachita K. Sumbria, Mher Mahoney Grigoryan, Vitaly Vasilevko, Tatiana B. Krasieva, Miriam Scadeng, Alexandra K. Dvornikova, Annlia Paganini-Hill, Ronald Kim, David H. Cribbs, Mark J. Fisher

Pharmacy Faculty Articles and Research

Background: Cerebral microhemorrhages (CMH) are tiny deposits of blood degradation products in the brain and are pathological substrates of cerebral microbleeds. The existing CMH animal models are β-amyloid-, hypoxic brain injury-, or hypertension-induced. Recent evidence shows that CMH develop independently of hypoxic brain injury, hypertension, or amyloid deposition and CMH are associated with normal aging, sepsis, and neurodegenerative conditions. One common factor among the above pathologies is inflammation, and recent clinical studies show a link between systemic inflammation and CMH. Hence, we hypothesize that inflammation induces CMH development and thus, lipopolysaccharide (LPS)-induced CMH may be an appropriate model to …

Therapeutic Raavrh10 Mediated Sod1 Silencing In Adult Sod1(G93a) Mice And Nonhuman Primates, Florie Borel, Gwladys Gernoux, Brynn Cardozo, Jake P. Metterville, Gabriela Toro Cabrera, Lina Song, Qin Su, Guang Ping Gao, Mai K. Elmallah, Robert H. Brown Jr., Christian Mueller

Christian Mueller

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, and …

Serum Levels Of Alpha-1 Antitrypsin Following Vascular Limb Or Intra-Muscular Delivery Of Aav1 Or Aav8 Gene Therapy Vectors In Rhesus Macaques, Alisha M. Gruntman, Gwladys Gernoux, Gensheng Wang, Janet M. Benson, Jeffrey D. Chulay, David R. Knop, Christian Mueller, Terence R. Flotte

Christian Mueller

Alpha-one antitrypsin (AAT) deficiency is a genetic disease that results in both lung disease and potentially liver failure in affected patients. In un-affected people AAT is produced in the liver and secreted to act as an anti-protease (primarily counteracting the effects of neutrophil elastase) in the lung. On-going human clinical trials have focused on intra-muscular delivery of adeno-associated virus (AAV1) to patients. The goal of delivery to the muscle is to have the myocytes serve as bio-factories to produce normal AAT protein and secrete it into the blood where it can exert its normal function in the lung. In the …

Sustained Expression With Partial Correction Of Neutrophil Defects 5 Years After Intramuscular Raav1 Gene Therapy For Alpha-1 Antitrypsin Deficiency, Terence R. Flotte, Christian Mueller, Gwladys Gernoux, Alisha Gruntman, Jeffrey D. Chulay, David R. Knop, Noel G. Mcelvaney, Martha Campbell-Thompson, James M. Wilson

Christian Mueller

Alpha-1 antitrypsin (AAT) deficiency is a common monogenic disorder resulting in emphysema, which is currently treated with weekly infusions of protein replacement. We previously reported achieving plasma wild-type (M) AAT concentrations at 2.5-3.8% of the therapeutic level at 1 year after intramuscular (IM) administration of 6×1012vg/kg of a recombinant adeno-associated virus serotype 1 (rAAV1)-AAT vector in AAT-deficient patients, with an associated regulatory T cell (Treg) response to AAV1 capsid epitopes in the absence of any exogenous immune suppression. Here, we report sustained expression at greater than 2% of the therapeutic level for 5 years after one-time treatment with rAAV1-AAT in …

Effect Of Taste Stimuli On Swallowing Function In Persons With Traumatic Injuries, Megan Asselin, Angela M. Dietsch

UCARE Research Products

Background

Swallowing disorders are prevalent and costly. As of now, there are limited therapeutic options available to treat them. Extant research in limited populations has suggested that swallowing mechanics can be improved by extremely sour liquids, but this has not been tested in traumatically injured populations. However, sour tastants are unpleasant, and more palatable taste mixtures have not been tested.

Methods

The quantitative data were extracted from an existing pool of de-identified video fluoroscopic swallowing studies (moving radiographs) obtained from traumatically injured young adults under another research protocol. Each participant completed swallows of custom-mixed plain, sour, and sweet-sour boluses. Positions …

Circumventing Cisplatin Resistance In Ovarian Cancers Through Reactivation Of P53 By Non-Cross-Resistant Platinum Analogs, Michelle Martinez-Rivera

Abstract

CIRCUMVENTING CISPLATIN RESISTANCE IN OVARIAN CANCERS THROUGH REACTIVATION OF P53 BY NON-CROSS-RESISTANT PLATINUM ANALOGS

Michelle Martinez-Rivera, B.S.

Advisory Professor: Zahid H. Siddik, Ph.D.

Cisplatin (cis-Pt), an anticancer platinum (Pt) drug, is used widely in the treatment of several malignancies, such as ovarian cancer. This Pt compound induces DNA damage, which results in p53 activation through post-translational modifications, mainly phosphorylation, culminating in execution of programmed cell-death. However, despite initial therapeutic response to cis-Pt, clinical resistance to this drug emerges leading to disease progression. Pt-resistance phenotypes have been associated with dysfunction in the p53 signaling pathway. Therefore, an effort to understand …

Developing A Data Repository Of Standard Concussion Assessment Clinical Data For Research Involving College Athletes, Arthur C. Maerlender, Jennifer Mize Nelson, Julie A. Honaker

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

In sports concussion research, obtaining quality data from a sufficient number of participants to reach statistical power has been a particular problem. In addition, the necessary requirements of accessibility, informed consent, and confidentiality must be met. There is need to develop more efficient and controlled methods for collecting data to answer research questions in this realm, but the ability to collect and store these data in an efficient manner at the local level is limited. By virtue of their training, neuropsychologists can play a key role in improving data collection quality. The purpose of this paper is to describe a …

This dissertation describes the purification and partial characterization of CBP from the epidermis of the monarch butterfly larvae (Danaus plexippus). A yellow protein-carotenoid complex was extracted from the yellow pigmented epidermal tissue from monarch butterfly larvae by homogenization. Additional steps in the purification process included differential precipitation with ammonium sulfate, cation and anion chromatography, and lastly size exclusion chromatography. Polyacrylamide gel electrophoresis demonstrates that a single protein was isolated (M-LBP) having a ~60 kDa molecular weight, the value has subsequently been confirmed by HR-tandem MS. Lutein is the sole carotenoid bound by M-LBP with a stoichiometry of the …

Reliability Of Clinical Evaluators Of Spasticity In Patients With Stroke, Tiffany Alvino, Shiney David, Chelsea Gendvil

Dissertations, Theses, and Capstone Projects

Spasticity is characterized by hyperexcitable stretch reflexes with amplitude increases in response to velocity dependent passive movement and resistance. Spasticity is the result of abnormal function of segmental and suprasegmental neuronal circuits. The objective of this study was to determine any positive correlation between three clinical evaluators of spasticity (i.e., the pendulum test, the patellar tendon tap test (PTT), and the Modified Ashworth scale) in their reliability to assess spasticity in people post-stroke. It was hypothesized that the use of force movement sensors along with surface electromyography increases the reliability of the standardized clinical tests. The results show that all …

Control System For 3d Printable Robotic Hand, Htoo Wai Htet

Honors Theses

Humanoid robotics is a growing area of research due to its potential applications in orthosis and prosthesis for human beings. With the currently available technologies, the most advanced robotic hands used in prosthetics or robotics can cost from $11,000 to $90,000, making it inaccessible to the general population of amputees and robotics hobbyists. Most of the features provided by these expensive technologies are superfluous to many users, creating a great gap in cost and services between users and technology. Using the emerging 3D printing technology, my project is to construct a 3D printed robotic hand that can reproduce as many …

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 ketogenic diet …

Alzheimer’s disease (AD) is characterized by two molecular pathologies: cerebral β-amyloidosis in the form of β-amyloid (Aβ) plaques and tauopathy in the form of neurofibrillary tangles, neuritic plaques, and neuropil threads. Until recently, only Aβ could be studied in humans using positron emission tomography (PET) imaging owing to a lack of tau PET imaging agents. Clinical pathological studies have linked tau pathology closely to the onset and progression of cognitive symptoms in patients with AD. We report PET imaging of tau and Aβ in a cohort of cognitively normal older adults and those with mild AD. Multivariate analyses identified unique …

Characterization Of Bacterial Pathogens Involved In Aerobic Vaginitis: Prevalence, Strain Characterization And Sequelae, Leslie A. Lafferty

Graduate School of Biomedical Sciences Theses and Dissertations

Aerobic vaginitis (AV) is a more recently defined infection that involves aerobic pathogenic bacteria that replace the normal flora of the vaginal tract. It is commonly mistaken for other vaginal infections, such as bacterial vaginosis (BV), because they share many common symptoms. AV leads to complications during pregnancy, such as premature delivery and amnion infection, and is diagnosed by indications that range from vaginal discharge to inflammation. Because this infection is difficult to diagnose differentially from other vaginal infections, it is important to determine what pathogens are involved in AV so that we may have the ability to detect them. …

Phantom Limb Pain, Stephanie J. Stockburger, Mandakini Sadhir, Hatim A. Omar

Pediatrics Faculty Publications

Phantom limb pain is pain that is perceived in a part of the body which is no longer present. It is estimated that 80 percent of amputees experience phantom limb pain. Although the term is “phantom limb pain” the feeling is often more of a burning, twisting, itching, or pressure sensation than pain. The exact mechanism of phantom limb pain is unknown although proposed mechanisms include pain origination from either the central nervous system or the peripheral nervous system. Since the exact mechanism of phantom limb pain is unknown, treating this pain may be difficult. Treatments include pharmacological and nonpharmacological. …

Oxytocin Receptor (Oxtr) Single Nucleotide Polymorphisms Indirectly Predict Prosocial Behavior Through Perspective Taking And Empathic Concern, Christa C. Christ, Gustavo Carlo, Scott F. Stoltenberg

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Engaging in prosocial behavior can provide positive outcomes for self and others. Prosocial tendencies contribute to the propensity to engage in prosocial behavior.The oxytocin receptor gene (OXTR) has also been associated with prosocial tendencies and behaviors. There has been little research, however, investigating whether the relationship between OXTR and prosocial behaviors is mediated by prosocial tendencies.This relationship may also vary among different types of prosocial behavior. The current study examines the relationship between OXTR, gender, prosocial tendencies, and both altruistic and public prosocial behavior endorsement. Students at a midwestern university (N = 398; 89.2% Caucasian; M …

Manuscripts, Articles, Book Chapters and Other Papers

Genomics is a promising tool that is becoming more widely available to improve the care and treatment of individuals. While there is much assertion, genomics will most certainly require the use of clinical decision support (CDS) to be fully realized in the routine clinical setting. The National Human Genome Research Institute (NHGRI) of the National Institutes of Health recently convened an in-person, multi-day meeting on this topic. It was widely recognized that there is a need to promote the innovation and development of resources for genomic CDS such as a CDS sandbox. The purpose of this study was to evaluate …

Extracorporeal Membrane Oxygenation (Ecmo) For Severe Toxicological Exposures: Review Of The Toxicology Investigators Consortium (Toxic)., G S. Wang, R Levitan, T J. Wiegand, Jennifer Lowry, R F. Schult, S Yin, Toxicology Investigators Consortium

Manuscripts, Articles, Book Chapters and Other Papers

Although there have been many developments related to specific strategies for treating patients after poisoning exposures, the mainstay of therapy remains symptomatic and supportive care. One of the most aggressive supportive modalities is extracorporeal membrane oxygenation (ECMO). Our goal was to describe the use of ECMO for toxicological exposures reported to the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC). We performed a retrospective review of the ACMT ToxIC Registry from January 1, 2010 to December 31, 2013. Inclusion criteria included patients aged 0 to 89 years, evaluated between January 2010 through December 2013, and received ECMO for …

Challenges Of Adoptive (T-)Cell Transfer Immunotherapy For Cancer, Aaron Volk

Biology: Student Scholarship & Creative Works

Background and significance: The rebirth of the theory of immunosurveillance in 2001 rejuvenated interest in anticancer immunotherapies. In particular, T-cell-based therapies have garnered substantial interest due to the robustness and tumor antigen-specific cytotoxicity of T-cell anticancer immune responses.

Hypothesis: The efficacy of adoptive cell transfer (ACT) T-cell immunotherapy could significantly improve and gain widespread approval if future innovations in ACT-based approaches account for the pro- and antitumoral properties of non-CD8⁺ lineages of effector T-cells, evasion of T-cell antitumor immunity, and tumor-induced suppression of antitumor immunity.

Problem Analysis: Despite numerous reports of highly successful ACT-based clinical trials, no such therapy …
