CRK and CRKL (CRK-like) encode adapter proteins with similar biochemical properties. Here, we show that a 50% reduction of the family-combined dosage generates developmental defects, including aspects of DiGeorge/del22q11 syndrome in mice. Like the mouse homologs of two 22q11.21 genes CRKL and TBX1, Crk and Tbx1 also genetically interact, thus suggesting that pathways shared by the three genes participate in organogenesis affected in the syndrome. We also show that Crk and Crkl are required during mesoderm development, and Crk/Crkl deficiency results in small cell size and abnormal mesenchyme behavior in primary embryonic fibroblasts. Our systems-wide analyses reveal impaired …

Demarcation Of Sepsis-Induced Peripheral And Central Acidosis With Ph (Low) Insertion Cycle Peptide, Kelly E. Henry, Aisling M. Chaney, Veronica L. Nagle, Haley C. Cropper, Saghar Mozaffari, Chip Slaybaugh, Keykavous Parang, Oleg A. Andreev, Yana K. Reshetnyak, Michelle L. James, Jason S. Lewis

Acidosis is a key driver for many diseases, including cancer, sepsis, and stroke. The spatiotemporal dynamics of dysregulated pH across disease remain elusive, and current diagnostic strategies do not provide localization of pH alterations. We sought to explore if PET imaging using hydrophobic cyclic peptides that partition into the cellular membrane at low extracellular pH (denoted as pH [low] insertion cycles, or pHLIC) can permit accurate in vivo visualization of acidosis. Methods: Acid-sensitive cyclic peptide c[E₄W₅C] pHLIC was conjugated to bifunctional maleimide-NO2A and radiolabeled with ⁶⁴Cu (half-life, 12.7 h). C57BL/6J mice were administered lipopolysaccharide (15 …

Synthesis And Preliminary Ex Vivo Testing Of Sirna Targeting Tcrb: A Proposed Therapy For The Treatment Of Autoimmunity, Nicholas J. Magazine

LSU Doctoral Dissertations

Abstract

Background:

As of 2018, the United States National Institutes of Health estimate that over half a billion people worldwide are affected by autoimmune disorders. Though these conditions are prevalent, treatment options remain relatively poor, relying primarily on various forms of immunosuppression which carry potentially severe side effects and often lose effectiveness overtime. Given this, new forms of therapy are needed. We propose small-interfering RNA (siRNA) for hypervariable regions of the T-cell receptor β-chain gene (TCRb) as a highly targeted, novel means of therapy for the treatment of autoimmune disorders.

Objectives:

To develop methods to produce siRNA targeting …

The Nuclear Legacy In Appalachia, Michele Morrone, Harold Perkins

Journal of Appalachian Health

Nestled in the rolling hills of Appalachia Ohio is a reminder of the role that the region played in winning the Cold War. For more than 40 years in rural Pike County, the 3,700-acre Portsmouth Gaseous Diffusion Plant (PORTS), or the “A-Plant” as the locals refer to it, enriched uranium for use in nuclear weapons. While the facility produced nuclear fuel for national security, it simultaneously exposed plant workers to chemicals and radiation and discharged pollution into the surrounding community. The A-Plant is now being demolished and the site repurposed. However, the site continues to affect the community as, for …

Experimental And Computational Tools For Single Cell Analysis In Cancer Diagnostics, Manibarathi Vaithiyanathan

LSU Doctoral Dissertations

Substantial evidence shows that cellular heterogeneity commonly exists within an isogenic or clonal population. Whether in isolation or caused through a combination of the above events, cellular heterogeneity can dramatically influence cellular decision making and cell fate, however, this can be masked by the average response from a population. One approach to solve this issue is to analyze a population at the individual cell level. The goal of this work is to develop high-throughput experimental and computational platforms to screen and quantify single cancer cells for specific intracellular enzyme activities. An interdisciplinary approach was taken to 1) better understand the …

De Jesus, Ishani Sheth, Hee Jin Kwon, Zhujun Gao, Jessica Palmer, Minji Hur, Thomas S. Hammack, Dumitru Macarisin, Yi Chen

United States Food and Drug Administration: Publications

In the summer of 2014, a multistate outbreak of listeriosis associated with contaminated stone fruit (peach and nectarine) was reported. A serotype 4b variant Listeria monocytogenes (Lm) strain of singleton Sequence Type (ST) 382 was isolated from clinical samples and stone fruit associated with the outbreak. A serotype 1/2b Lm strain of ST5, Clonal Complex 5 was isolated only from outbreak-associated stone fruit, not from clinical samples. Here we investigated the fate of the serotype 4b and 1/2b strains, at two inoculation levels (high level at 3.7 logCFU/fruit and low level at 2.7 logCFU/fruit), on the surfaces of white peach, …

An Evaluation Of The Usda's Policy To Reduce Listeria Illnesses In Ready‐To‐Eat Meat And Poultry Products, Travis Minor, Matt Parrett

United States Food and Drug Administration: Publications

Using 1998–2008 data collected by the Centers for Disease Control and Prevention on foodborne illnesses and outbreaks, we examine the economic impact of the United States Department of Agriculture's proposed and final rules to reduce the incidence of Listeria monocytogenes (Lm) in ready‐to‐ eat meat and poultry products. Using a difference‐in‐ differences approach, we find that these rules together reduced meat‐related Lm illnesses by about 60 per year, which we attribute to reductions in both the number and average size of meat‐related Lm outbreaks. We then monetize this illness reduction using an underreporting and underdiagnosis multiplier of 2.3 and an …

Genomics-Based Re-Examination Of The Taxonomy And Phylogeny Of Human And Simian Mastadenoviruses: An Evolving Whole Genomes Approach, Revealing Putative Zoonosis, Anthroponosis, And Amphizoonosis, June Kang, Ashrafali Mohamed Ismail, Shoaleh Dehghan, Jaya Rajaiya, Marc W. Allard, Haw Chuan Lim, David W. Dyer, James Chodosh, Donald Seto

United States Food and Drug Administration: Publications

With the advent of high-resolution and cost-effective genomics and bioinformatics tools and methods contributing to a large database of both human (HAdV) and simian (SAdV) adenoviruses, a genomics-based re-evaluation of their taxonomy is warranted. Interest in these particular adenoviruses is growing in part due to the applications of both in gene transfer protocols, including gene therapy and vaccines, as well in oncolytic protocols. In particular, the re-evaluation of SAdVs as appropriate vectors in humans is important as zoonosis precludes the assumption that human immune system may be na€ıve to these vectors. Additionally, as impor- tant pathogens, adenoviruses are a model …

The Impact Of The Abuse-Deterrent Reformulation Of Extended-Release T Oxycontin On Prescription Pain Reliever Misuse And Heroin Initiation, Carolyn Wolff, William N. Dowd, Mir M. Ali, Chandler Mcclellan, Angelica Meinhofer, Lukas Glos, Ryan Mutter, Matthew Rosenberg, Andreas Schikc

United States Food and Drug Administration: Publications

The introduction of abuse-deterrent OxyContin in 2010 was intended to reduce its misuse by making it more tamper resistant. However, some studies have suggested that this reformulation might have had unintended consequences, such as increases in heroin-related deaths. We used the 2005–2014 cross-sectional U.S. National Survey on Drug Use and Health to explore the impact of this reformulation on intermediate outcomes that precede heroin-related deaths for individuals with a history of OxyContin misuse. Our study sample consisted of adults who misused any prescription pain reliever prior to the reformulation of OxyContin (n = 81,400). Those who misused OxyContin prior to …

Development Of A Nicotinic Acetylcholine Receptor Nachr Α7 Binding Activity Prediction Model, Sugunadevi Sakkiah, Carmine Leggett, Bohu Pan, Wenjing Guo, Luis G. Valerio Jr., Huixiao Hong

United States Food and Drug Administration: Publications

Despite the well-known adverse health effects associated with tobacco use, addiction to nicotine found in tobacco products causes difficulty in quitting among users. Nicotinic acetylcholine receptors (nAChRs) are the physiological targets of nicotine and facilitate addiction to tobacco products. The nAChR-α7 subtype plays an important role in addiction; therefore, predicting the binding activity of tobacco constituents to nAChR-α7 is an important component for assessing addictive potential of tobacco constituents. We developed an α7 binding activity prediction model based on a large training data set of 843 chemicals with human α7 binding activity data extracted from PubChem and ChEMBL. The model …

United States Food and Drug Administration: Publications

Objective: Many veterans of the Iraq and Afghanistan Wars have experienced traumatic brain injury (TBI). Although prior work has examined associations between TBI and development of psychi- atric syndromes, less is known about associations between TBI and component emotions constituting these syndromes, especially in the long term. The purpose of this study was to examine the long-term emotional consequences of deployment-related TBI.

Methods: As part of VA Cooperative Studies Program #566, we assessed a sample of n1⁄4456US Army soldiers prior to an index deployment to Iraq, and again an average of 8.3 years (SD1⁄42.4years) after their deployment for a long-term …

Silver Salt-Mediate Benzylation Of Carbohydrates Under Mildly Acidic Conditions, Nicholas Forsythe, Samira Escopy, Yashapal Singh 2436808, Alexei Demchenko

Undergraduate Research Symposium

When looking at biomolecules, carbohydrate represent a large group of macromolecules that play an important role in the body. Most importantly, carbohydrates provide an energy supply for organisms, but it is proven that they are also involved in a myriad of other processes. Furthermore, synthesizing these molecules leads to advancements in chemistry, such as drug design, and other structures such as glycolipids play important roles in the immune system. Understanding this, an efficient and reliable way to create these carbohydrates is needed.

The protection and deprotection manipulations of carbohydrates play an essential role in synthetic carbohydrate chemistry.¹ Using benzyl …

Hsp90 Inhibitors For Ipf/Covid-19, Ruben Manuel Luciano Colunga Biancatelli, Pavel A. Solopov, John Catravas

Bioelectrics Publications

Heat shock protein 90 (HSP90) is an important chaperone that assists the late stage folding of several proteins involved in cell survival in response to environmental stressors. The inhibition of HSP90 is followed by a complex modulation of the proteome and the kinome, that has proved beneficial in cancer and various neurodegenerative diseases. Additionally, accumulating literature suggests that HSP90 may be a key target during the development of pulmonary fibrosis and that its inhibition could serve as a new and exciting therapeutic approach. We have summarized the current evidence about HSP90’s role in Idiopathic Pulmonary Fibrosis (IPF), the results from …

Stimuli-Responsive Gelators From Carbamoyl Sugar Derivatives And Their Responses To Metal Ions And Tetrabutylammonium Salts, Dan Wang, Anji Chen, Joedian Morris, Guijun Wang

Chemistry & Biochemistry Faculty Publications

Carbohydrate-based low molecular weight gelators (LMWGs) are interesting compounds with a variety of applications. In this research, a library of nineteen carbamate derivatives of N-acetyl-D-glucosamine were synthesized and characterized, and several derivatives were found to be effective LMWGs. They formed gels in pump oils as well as mixtures of water with ethanol or water with DMSO. The structures of the carbamoyl chains played an important role in the gelation properties, short chain aliphatic derivatives and phenyl carbamates formed gels in more solvents than certain aromatic and dimeric carbamates. The phenyl carbamate gelator was also selected for the encapsulation of …

Singlet Oxygen Generation By Porphyrins And Metalloporphyrins Revisited: A Quantitative Structure-Property Relationship (Qspr) Study, Andrey A. Buglak, Mikhail Filatov, Althaf M. Hussain, Manabu Sugimoto

Books/Book chapters

state followed by formation of singlet oxygen (1O2), which is a highly reactive species and mediates various oxidative processes. The design of advanced sensitizers based on porphyrin compounds have attracted significant attention in recent years. However, it is still difficult to predict the efficiency of singlet oxygen generation for a given structure. Our goal was to develop a quantitative structure-property relationship (QSPR) model for the fast virtual screening and prediction of singlet oxygen quantum yields for pophyrins and metalloporphyrins. We performed QSPR analysis of a dataset containing 32 compounds, including various porphyrins and their analogues (chlorins and bacteriochlorins). Quantum-chemical descriptors …

The Substantiality Of The Neuroplasticity Hypothesis Of Major Depressive Disorder: The Prospective Use Of Ketamine-Like Drugs As Antidepressants, Roma Kankaria

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Abstract

Major depressive disorder (MDD) affects approximately 17.3 million adults in the United States each year. For more than 50 years, the serotonin hypothesis of MDD, which hypothesizes that a deficiency of monoaminergic neurotransmitters results in depression, has been the foundation for neuropsychological research. However, studies reveal that only an estimated 50% of MDD patients respond to traditional, biogenic-amine-based antidepressants (ADs), like selective serotonin reuptake inhibitors (SSRIs). Research has noted that the neuroplasticity hypothesis, which posits that weakened excitatory synaptic transmission results in depression, offers an alternative mechanism by which ketamine-like drugs lacking the abuse liability and psychoactive effects of …
