Generation And Characterization Of Hla-Universal, Ipsc-Derived Platelets, Phatchara Norbnop Jan 2017

Generation And Characterization Of Hla-Universal, Ipsc-Derived Platelets, Phatchara Norbnop

Chulalongkorn University Theses and Dissertations (Chula ETD)

Platelet demand has been increased around the world resulting from many factors including the rise of aging population, hematological malignancy incidence, and hematopoietic stem cell transplantation. In addition, inadequacy of donors or matched donors, time consuming, cost, the risk of transfusion-transmitted infections and transfusion-associated reactions, and platelet transfusion refractoriness are limits of this approach. To solve these problems, here we propose to generate platelets in vitro which do not induce alloimmunity to HLA class I, a major cause of immune factors in platelet transfusion refractoriness. In this study, we have knocked out β2-microglobulin gene (β2m) in iPSCs using paired CRISPR/Cas9 …

Effect Of Calcium Citrate In Calcium Carbonate Nanoparticles On Hk-2 Cells In Acidic Environment, Tipagorn Udomsinsirikul Jan 2017

Effect Of Calcium Citrate In Calcium Carbonate Nanoparticles On Hk-2 Cells In Acidic Environment, Tipagorn Udomsinsirikul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Metabolic acidosis exerts several cellular and tissue dysfunctions, such as increases mineral bone and protein degradation, induces inflammation, oxidative stress and cell death. These complications lead to multiple organ failure, including chronic kidney disease. Sodium bicarbonate and Shohl's solution are commonly used to treat metabolic acidosis. However, these agents cause frequent gastrointestinal adverse effects. Hence, we invented the new calcium carbonate nanoparticles to use as a drug delivery system for carrying citrate to renal cell which we hypothesize to reduce adverse effects of metabolic acidosis. We studied the physical characteristics and pharmacological effects of calcium citrate nanoparticle (Cacit) and calcium …

Modulation Of Pkr Activity During Hiv Infection And Cellular Stress By Pact And Trbp, Evelyn E. Chukwurah Jan 2017

Modulation Of Pkr Activity During Hiv Infection And Cellular Stress By Pact And Trbp, Evelyn E. Chukwurah

Theses and Dissertations

A crucial component of the cellular response to stress is the attenuation of protein synthesis to allow the cell to dedicate resources for the restoration of homeostasis or towards the induction of apoptotic cell death in case the stressors overwhelm the cell. This process is itself regulated by one of the four eIF2α kinases of which PKR (Protein Kinase R) is responsible for inhibiting general translation during viral infection, oxidative stress, ER stress, heat shock or serum withdrawal.

During viral infection, PKR is transcriptionally induced by interferon but remains latent until it interacts with dsRNA. This interaction induces a conformational …


The Effect Of Acute Pain On Executive Function, Jenna M. Morogiello Jan 2017

The Effect Of Acute Pain On Executive Function, Jenna M. Morogiello

College of Graduate Studies: Theses & Dissertations

Background: Executive functions are high-level cognitive processes that allow a person to successfully engage in an independent and self-fulfilling life. Previous literature indicates that acute pain can affect executive function, which may be due to a limited amount of shared neural resources of the brain.

Objective: The purpose of this study was to determine if acute pain affects executive function in recreationally active individuals who sustain a musculoskeletal injury.

Methodology: Twenty-four participants who presented with acute pain due to a musculoskeletal injury underwent a neuropsychological battery within 72 hours of injury and within two weeks from the initial testing session. …


Visualizing Morphogenesis With The Processing Programming Language, Avik Patel, Amar Bains, Richard Millet, Tamira Elul Jan 2017

Visualizing Morphogenesis With The Processing Programming Language, Avik Patel, Amar Bains, Richard Millet, Tamira Elul

Faculty Publications & Research of the TUC College of Osteopathic Medicine

We used Processing, a visual artists’ programming language developed at MIT Media Lab, to simulate cellular mechanisms of morphogenesis – the generation of form and shape in embryonic tissues. Based on observations of in vivo time-lapse image sequences, we created animations of neural cell motility responsible for elongating the spinal cord, and of optic axon branching dynamics that establish primary visual connectivity. These visual models underscore the significance of the computational decomposition of cellular dynamics underlying morphogenesis.

Serious mental illness (SMI) is disabling, and current interventions are ineffective for many. This exploratory study sought to demonstrate the feasibility of applying topological data analysis (TDA) to resting-state functional connectivity data obtained from a heterogeneous sample of 235 adult inpatients to identify a biomarker of treatment response. TDA identified two groups based on connectivity between the prefrontal cortex and striatal regions: patients admitted with greater functional connectivity between these regions evidenced less improvement from admission to discharge than patients with lesser connectivity between them. TDA identified a potential biomarker of an attenuated treatment response among inpatients with SMI. Insofar …


The Neurobiological Mechanisms Of Generalized Anxiety Disorder And Chronic Stress, Michelle A Patriquin, Sanjay J Mathew Jan 2017

The Neurobiological Mechanisms Of Generalized Anxiety Disorder And Chronic Stress, Michelle A Patriquin, Sanjay J Mathew

Staff and Researcher Publications

Two classification systems are now at the forefront of clinical psychiatric research: (1) Diagnostic and Statistical Manual, Fifth Edition and (2) the National Institutes of Mental Health Research Domain Criteria. Herein, we propose that these two classification systems are complementary rather than mutually exclusive, and when combined provide important information for understanding aspects of the pathophysiology related to Generalized Anxiety Disorder (GAD). The neurobiological literature for GAD and one relevant research domain criteria component, sustained threat, are reviewed from multiple units of analysis (genetic, neuroimaging, neuroendocrine, and psychophysiological). It is hypothesized that generating a comprehensive, biologically based understanding of the …


Robustness, Flexibility, And Sensitivity In A Multifunctional Motor Control Model, David N. Lyttle, Jeffrey P. Gill, Peter J. Thomas, Hillel J. Chiel Dec 2016

Robustness, Flexibility, And Sensitivity In A Multifunctional Motor Control Model, David N. Lyttle, Jeffrey P. Gill, Peter J. Thomas, Hillel J. Chiel

Faculty Scholarship

Motor systems must adapt to perturbations and changing conditions both within and outside the body. We refer to the ability of a system to maintain performance despite perturbations as “robustness,” and the ability of a system to deploy alternative strategies that improve fitness as “flexibility.” Different classes of pattern-generating circuits yield dynamics with differential sensitivities to perturbations and parameter variation. Depending on the task and the type of perturbation, high sensitivity can either facilitate or hinder robustness and flexibility. Here we explore the role of multiple coexisting oscillatory modes and sensory feedback in allowing multiphasic motor pattern generation to be …

Efficient Method For Transfer Of Microinjected Eggs To Mouse Ampulla For Generating Transgenic Mice, Guang Wen, Jin Di, Qian Li, Jianling Chen, Ling Jin, Cheng Wang, Sanqing Xu

Publications and Research

Background: The new method described here is highly efficient in transferring microinjected mouse eggs (MEs) through the bursa membrane of a surrogate mother mouse to the ampulla of the oviduct without damaging the blood vessels on the bursa membrane.

Results: This method causes no loss of blood, and it produces newborn pups/founders from approximately 70% of the transferred MEs, because only a small hole is made on the blood vessel–free area of the bursa membrane and ampulla of the surrogate mother mouse. The infundibulum remains intact. The small hole on the bursa membrane/ ampulla may already heal up before the …

Smith, K. L. Chapman, A. R. Scheer-Cohen, M. M.C. Demille, A. K. Adams, Alejandro Q. Nato Jr., E. M. Wijsman, J. D. Eicher, J. R. Gruen

Biochemistry and Microbiology

Verbal trait disorders encompass a wide range of conditions and are marked by deficits in five domains that impair a person’s ability to communicate: speech, language, reading, spelling, and writing. Nonword repetition is a robust endophenotype for verbal trait disorders that is sensitive to cognitive processes critical to verbal development, including auditory processing, phonological working memory, and motor planning and programming. In the present study, we present a six-generation extended pedigree with a history of verbal trait disorders. Using genome-wide multipoint variance component linkage analysis of nonword repetition, we identified a region spanning chromosome 13q14–q21 with LOD = 4.45 between …

In The Postoperative Cardiothoracic Surgical Patient Being Mechanically Ventilated, Is There A Difference In Outcomes When Comparing Sedation With Dexmedetomidine Versus Propofol?, Benjamin Heinrich Riebesel

Doctoral Projects

Patients undergoing a cardiothoracic operation typically require mechanical ventilation in the postoperative phase. Each year approximately 395,000 of these operations are performed in the United States alone. As many as 10% of these patients require reoperation within the first few hours of recovery due to complications (Barash & Cullen, 2013). This comprehensive review of the literature was performed to determine whether postoperative sedation with dexmedetomidine leads to better patient outcomes than sedation with propofol. Inclusion criteria included publications written in the English language, articles available in full text, articles written within the last 10 years, and publications with a focus …

Adoption Of Perioperative Lidocaine Infusion For The Reduction Of Postoperative Pain, Brandon Scott Figueiredo

Doctoral Projects

Laparoscopic capability provides numerous benefits to patients requiring abdominal surgical procedures. However, the use of these techniques has presented the anesthesia provider with a unique set of challenges in terms of perioperative management and postoperative pain reduction. No standardized method has existed to reduce postoperative pain and improve recovery following these procedures. There were three primary goals of this project. The first goal was to conduct a meta-analysis of randomized controlled trials to determine the benefit of the use of intravenous lidocaine infusions to reduce postoperative pain in laparoscopic abdominal surgery. Twelve articles were included in the meta-analysis that pertained …

Oral Carbohydrate Administration Prior To Colorectal Surgery: Practice Change Outcomes And Economic Analysis, Joshua Kendrick Ezelle

Doctoral Projects

Difference in recovery times has been an interest of mine for many years. I observed that an open heart surgery routinely recovered and discharged on the third post-op day, while a colorectal patient often required a hospital stay of five to ten days. I began researching recovery methods of colorectal patients. I found enhanced recovery techniques like decreased narcotic, use of NSAID’s, early ambulation, and the use of medications that assist with bowel peristalsis are being employed nationally. Other techniques are now starting to be used with positive results. One of these is Carb-loading. Carb-loading is the oral intake of …

Anti-Tumor Mechanisms Of Hpv16 E6*, Whitney S. Evans

Loma Linda University Electronic Theses, Dissertations & Projects

High-risk types of the human papillomavirus (HR-HPV) are the causative agents of nearly all cases of cervical cancer, as well as a significant number of head, neck, penile, vulvar and anal cancers. Like many other viruses with small genomes, HPV (~8 kb) utilizes numerous mechanisms to increase the capacity of its genome to encode the proteins necessary for successful completion of its infectious life cycle, including alternative splicing. Studies over the past few decades have focused intensively on the activities and roles of E6 proteins from HR-HPVs during the process of cellular transformation, clearly implicating E6 as a major transforming …

Effect Of The Butyrate Prodrug Pivaloyloxymethyl Butyrate (An9) On A Mouse Model For Spinal Muscular Atrophy., Jonathan D. Edwards, Matthew E.R. Butchbach

Department of Pediatrics Faculty Papers

Spinal muscular atrophy (SMA) is an early-onset motor neuron disease that leads to loss of muscle function. Butyrate (BA)-based compounds markedly improve the survival and motor phenotype of SMA mice. In this study, we examine the protective effects of the BA prodrug pivaloyloxymethyl butyrate (AN9) on the survival of SMNΔ7 SMA mice. Oral administration of AN9 beginning at PND04 almost doubled the average lifespan of SMNΔ7 SMA mice. AN9 treatment also increased the growth rate of SMNΔ7 SMA mice when compared to vehicle-treated SMNΔ7 SMA mice. In conclusion, BA prodrugs like AN9 have ameliorative effects on SMNΔ7 SMA mice.

Temporary Nerve Block At Selected Digits Revealed Hand Motor Deficits In Grasping Tasks, Aude Cateron, Kerry Mcpartlan, Christina Gioeli, Emily Reid, Matt Turturro, Barry Hahn, Cynthia Benson, Wei Zhang

Publications and Research

Peripheral sensory feedback plays a crucial role in ensuring correct motor execution throughout hand grasp control. Previous studies utilized local anesthesia to deprive somatosensory feedback in the digits or hand, observations included sensorimotor deficits at both corticospinal and peripheral levels. However, the questions of how the disturbed and intact sensory input integrate and interact with each other to assist the motor program execution, and whether the motor coordination based on motor output variability between affected and non-affected elements (e.g., digits) becomes interfered by the local sensory deficiency, have not been answered. The current study aims to investigate the effect of …
