Elucidating The Role Of The Α7 Nicotinic Receptor In The Etiology Of Schizophrenia., Michelle Johnson Chandley
Electronic Theses and Dissertations
The α7 subunit of the nicotinic receptor, a ligand gated ion channel with an affinity for nicotine, has long been implicated in the pathophysiology of schizophrenia due to the extremely high rate of smoking within the patient population. However, the exact role of the receptor has never fully been determined. In the following studies, various functions the receptor may assume in disease state are evaluated. There is a strong relationship between the immune system and schizophrenia, with the α7 subunit possibly serving as the link between the two. One of the following studies looks at the possibility of the receptor …

The Role Of Msa In The Global Regulation Of Virulence In Staphylococcus Aureus, Vijayaraj Nagarajan
Dissertations
Staphylococcus aureus is an important pathogen causing life threatening diseases in humans. Previously we showed that msa modulates the activity of sarA (Staphylococcal accessory regulator), which is one of a major global regulator of virulence in S. aureus. The objective of this study is to characterize the role of msa (Modulator of SarA) in the global regulation of virulence in S. aureus. Structure and function predictions were done using several computational tools and approaches to understand the nature of msa. A novel S. aureus microarray meta-database (SAMMD) was designed and developed to compare and contrast other transcriptomes with msa transcriptome. …

Anti-Inflammatory Effects Of Ppar-Gamma In Surgical Brain Injury (Sbi), Amy Hyong
Anti-Inflammatory Effects Of Ppar-Gamma In Surgical Brain Injury (Sbi), Amy Hyong
Loma Linda University Electronic Theses, Dissertations & Projects
Introduction: Brain injury can be caused by neurosurgical procedures themselves, due to direct trauma, retractor stretch, intraoperative hemorrhage and electrocautery damage. As a result of this surgical brain injury (SBI) postoperative complications such as inflammation, brain edema, and cell death can occur in the susceptible brain areas. Cerebral inflammation is a known contributor to the pathophysiology of brain injury. Following brain injury, the release of inflammatory mediators facilitates the development of BBB breakdown, cerebral edema, oxidative stress and neuronal death, resulting in further tissue damage in the brain and poor neurological outcomes. This study evaluates whether the use of a …
Characterization Of Kaposi's Sarcoma-Associated Herpesvirus Orf11 As A Possible Dutpase, Christina N. Ramirez
Characterization Of Kaposi's Sarcoma-Associated Herpesvirus Orf11 As A Possible Dutpase, Christina N. Ramirez
Seton Hall University Dissertations and Theses (ETDs)
A dUTPase is a crucial enzyme that hydrolyzes dUTP to dUMP. This reaction prevents the mutagenic or lethal misincorporation of uracil into DNA. For that reason, the enzyme is required for efficient DNA replication. Previous studies have shown that has ORFl l dUTPase-like motifs and thus may be a dUTPase. Generally, gammaherpesviruses contain six characteristic dUTPase motifs. In particular ORFl 1 and contains motifs 1, 2, 4, 6. While the characteristic motifs of gamroaberpesviruses include motifs 1, 2, 3, 4, 5, and 6, the number of dUTPase-like motifs in ORFl 1 's protein sequence is substantial. Thus, ORFl 1 may …

Nanosecond Pulsed Electric Fields Induce A Mitochondria-Independent Apoptosis In B16f10 Melanoma Cells In Vitro, Wentia Elissa Ford
Theses and Dissertations in Biomedical Sciences
Nanosecond pulsed electric fields (nsPEFs) are ultra-short pulses that induce direct electric field and biological effects that initiate apoptosis. Here the application of ten 300ns pulses ranging in electric fields from 12kV/cm-60kV/cm was administered to determine the effects on B16F10 melanoma cells evaluated by in vitro studies. Initial application of nsPEFs demonstrated apoptosis induction in an electric field- and pulse number-dependent manner measured by caspase activation that correlated with decrease in cell viability 24hr post pulse. In addition caspase activity was shown to be independent of calcium mobilization though ions may play a part in other aspects of apoptosis. The …

Oxidative Stress-Mediated Anticancer Activity Of Novel Ahr Modulators Af & 5f203, Lancelot S. Mclean
Loma Linda University Electronic Theses, Dissertations & Projects
Estrogen receptor positive (ER+) breast cancer tends to respond to anti-estrogen agents such as Tamoxifen. Approximately 40% of ER+ breast cancer is resistant to these agents and those that initially respond often acquire resistance. Estrogen receptor negative (ER-) breast cancer remains largely unresponsive to these agents. It is therefore vital to discover drugs that are potent in both forms of breast cancer. Aminoflavone, (5-amino-2, 3-fluorophenyl)-6,8-difluoro-7-methyl-4H-l-benzopyran-4-one; AF; NSC 686288) and 5F203, (2-[-Amino-3-methy phenyl]-5-flurobenzothiazole) are novel anticancer candidate agents that display potent in vitro and in vivo anti-proliferative activity against select human tumor cells with a unique anticancer activity profile in the …
Neuronal Connections From The Cervix To The Spinal Cord Before Parturition, Mary Medina Groves
Neuronal Connections From The Cervix To The Spinal Cord Before Parturition, Mary Medina Groves
Loma Linda University Electronic Theses, Dissertations & Projects
By the day before birth, the density of nerve fibers in the cervix has increased compared to earlier in pregnancy or in nonpregnant mice. Similar findings are reported in parturient women. To test the hypothesis that connections between the cervix and spinal cord are enhanced by term, the cervix of nonpregnant and time-dated pregnant mice (day 15 or 18 post-breeding) was injected with pseudorabies virus (PRV), a trans-synaptic retrograde neural tract tracer. Mice were euthanized and perfused 5 days later. The spinal cord and cervix were removed and postfixed overnight, immersed in sucrose, and cryostat sections through the thoracic to …
Response Of Endothelial Cells To Stressors: The Impact Of Aging And Diabetes, Katie Mclellan
Response Of Endothelial Cells To Stressors: The Impact Of Aging And Diabetes, Katie Mclellan
Loma Linda University Electronic Theses, Dissertations & Projects
Preliminary research indicates there is some impairment of the endothelial cells to respond to single stressors such as local heat, shear stress, and global heat in older people and people who have diabetes. The response of the skin blood flow to local heat is an indicator of the endothelial cells ability to cope with stress. In addition, factors such as thicker subcutaneous fat and skin moisture may impair the skin’s ability to dissipate heat. For older people and people with diabetes, this endothelial dysfunction may cause an even more diminished response to multiple stressors. However, no studies have examined the …
Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel
Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel
Loma Linda University Electronic Theses, Dissertations & Projects
Research suggests that individuals who undergo coronary artery bypass grafting (CABG) experience declines in neuropsychological functioning post-operatively. This decline has been observed in up to 80% of patients early after surgery, and in up to 30% of patients after six months. Many studies have examined the potential effects of CABG on neuropsychological functioning in general, and numerous studies have found that executive functions are impaired in particular. However, none have examined what factors contribute to observed executive dysfunction after CABG. This study investigated the role of memory functions on executive functions in a selected sample of patients undergoing CABG. This …
Novel Binding Domains Mediate Binding Of Hpv 16 E6 To Fadd And Procaspase 8, Sandy S. Tungteakkhun
Novel Binding Domains Mediate Binding Of Hpv 16 E6 To Fadd And Procaspase 8, Sandy S. Tungteakkhun
Loma Linda University Electronic Theses, Dissertations & Projects
To evade the host response to infection, viruses have developed means to survive and propagate. HPV 16, a causative agent of cervical cancer and of some cases of oropharyngeal cancers, is one example. We have reported that the early viral protein E6 binds to proteins necessary for propagation of the apoptotic signal following receptor/ligand interactions, such as those mediated by FADD DED and procaspase 8 DED. E6 expression leads to the dose-dependent accelerated degradation of FADD and the protection of E6-expressing cells from Fas-induced apoptosis. Surprisingly, the splice isoforms of E6, E6large and E6*, affect the stability of procaspase …
Mechanisms Of T Helper Cell Modulation In A Simulated Space Radiation Environment, Asma Rizvi
Mechanisms Of T Helper Cell Modulation In A Simulated Space Radiation Environment, Asma Rizvi
Loma Linda University Electronic Theses, Dissertations & Projects
Exposure to solar particle events (SPEs) poses the most serious threat to astronaut health. Due to this radiation environment, exploration of the solar system beyond Earth’s orbit entails many risks for the crew on these deep space missions. Depression or dysfunction of the immune system is a major concern due to its high radio-sensitivity; potential consequences include overwhelming infection, development of cancer, fibrosis, and poor wound healing. Astronauts are also exposed to low dose/low dose rate (LDR) radiation. A three month stay at the international space station exposes them to ~ 0.05 Gy of radiation.
C57BL/6 mice received LDR gamma-radiation …
Use Of Monoclonal ∆-9-Tetrahydrocannabinol Antibodies Chemically Bound To A Polystyrene Surface Using Glutaraldehyde For The Purpose Of Extracting ∆-9-Tetrahydrocannabinol And ∆-9-Tetrahydrocannabinol Carboxylic Acid From Postmortem Whole Blood Samples For Analysis By Gas Chromatography Mass Spectrometry, Thomas Sidney Pittman
Dissertations
Quantitations of drugs and their respective metabolites in postmortem blood samples using gas chromatographic instrumentation is a primary analytical practice used to determine if drugs played a role in or were the cause of a victim's death. Postmortem blood samples often prove difficult to work with due to interfering substances formed during the putrefaction process. Attempts to eliminate interfering substances with present day extraction methods can be time-consuming, costly and often ineffective when dealing with drugs that exhibit toxicity or impairment at very low concentrations. This study was conducted using monoclonal antibodies chemically bound to a polystyrene surface to extract …
Analysis Of The Cyc1 Promoter In Candida Albicans, Tomica Blocker
Analysis Of The Cyc1 Promoter In Candida Albicans, Tomica Blocker
McCabe Thesis Collection
Scientists are considering two factors that may be important in the pathogenesis of C. albicans', it's capability to morph from yeast to hyphal phase, and its differences in colony morphology, cell shape, cell surface and cell permeability. (5) Unfortunately, unlike the bacteria, yeasts do not yet have proven virulence factors. However, science is suggesting that some of the major factors which contribute to the virulence of Candida are its ability to form hyphae, its ability to resist phagocytosis, its ability to adhere to epithelial cell surfaces, its ability to grow well at 37 degrees Celsius, and its ability to secrete …
Pathophysiology Of Arbroviral Encephalitides In Laboratory Rodents, Aaron L. Olsen
Pathophysiology Of Arbroviral Encephalitides In Laboratory Rodents, Aaron L. Olsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Western equine encephalitis virus (WEEV) is an arboviral pathogen naturally found in North America. The primary disease phenotype associated with WEEV infection in susceptible hosts is a relatively long prodromal period followed by viral encephalitis. By contrast, in the current work, experimental inoculation of WEEV into the peritoneum of Syrian golden hamsters produced rapid death within approximately 96 h. It was determined that direct virus killing of lymphoid cells leads to death in WEEV-infected Syrian golden hamsters, and that inflammatory cytokines have the potential to enhance virus-induced lymphoid cell destruction. It was further concluded that WEEV retains its ability to …

Glycemic Load And Risk Of Alzheimer's Disease: The Cache County Study On Memory, Health, And Aging, Eun Young Choi
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Carbohydrates are a major energy source for the human body and particularly glucose is the only energy source for the brain. Thus glucose metabolism is important to maintain normal brain function. Evidence showed insulin resistance and diabetes are associated with cognitive decline and a large amount of highly processed carbohydrate intake; in other words, a high glycemic load diet, which increases blood glucose faster and insulin demand, is associated with increased risk of insulin resistance and diabetes.
Based on this premise, the hypothesis that a high glycemic load (GL) diet increases the risk of incident Alzheimer’s disease (AD) was examined …
Cannabinoids: A Novel Treatment Strategy For Retinal Neurodegenerative Disorders, Sandeep Samudre
Cannabinoids: A Novel Treatment Strategy For Retinal Neurodegenerative Disorders, Sandeep Samudre
Theses and Dissertations in Biomedical Sciences
Synthetic and naturally occurring cannabinoids are known to decrease intraocular pressure (IOP). Glaucomatous damage to the retina and optic nerve progresses even after therapy to maintain normal intraocular pressure (IOP). Topical application of cannabinoids decreases IOP while not affecting blood pressure or heart rate. Based upon their effects on other tissues, we hypothesize that these analogs reduce IOP and may also confer direct neuroprotective effects on the retina, possibly via CB1 and/or CB2 receptors. The purpose of this study is to determine if the newly synthesized CB agonists, lipid soluble O-1812 (CB 1), and water soluble O-2545 (CB 1
The …
Three Models Of Anthrax Toxin Effects On The Map-Kinase Pathway And Macrophage Survival, Daniel J. Schneider
Three Models Of Anthrax Toxin Effects On The Map-Kinase Pathway And Macrophage Survival, Daniel J. Schneider
Theses and Dissertations
Lethal factor (LF), a component of anthrax toxin, is the primary virulence factor that allows Bacillus anthracis to evade the immune response by blocking the activation of mitogen-activated protein kinase (MAPK) enzymes. This research modifies three published MAPK models to reflect this signal inhibition and to estimate a first-order reaction rate by fitting the models to published viability data for two macrophage cell lines cultured with the LF-producing Bacillus anthracis-Vollum1B strain. One model appears to be ill-suited for this purpose because not all relevant MAPK components could be integrated into the inhibition equations. Despite different underlying parameters and values, the …

In Vitro Toxicity Of Aluminum Nanoparticles In Human Keratinocytes, Stephanie Mccormack-Brown
Theses and Dissertations
Nanotechnology promises to be the defining technology of the 21st century. At an annual investment of $1B, it provides significant contributions to manufacturing, medicine, energy conservation, and the environment. Nanoparticles are structures with at least one dimension in the 1 to 100 nanometer (nm) range. DoD and US Air Force interest in aluminum nanoparticles (AL NPs) stems from its ability to enhance combustion jet fuel, thus increasing fuel efficiency. The addition of AL NPs to JP-8 may pose a unique dermal hazard to aircraft maintenance workers. There is no published data on AL NP toxicity effects on human skin. This …
Radiation-Induced Glutamate Transport Alterations In Neuron-Astrocyte Coupling, Martha Celia Sanchez
Radiation-Induced Glutamate Transport Alterations In Neuron-Astrocyte Coupling, Martha Celia Sanchez
Loma Linda University Electronic Theses, Dissertations & Projects
Exposure of the central nervous system (CNS) to ionizing radiation is known to result in behavioral, cognitive, and motor deficits - effects similar to those seen in many neurodegenerative disorders. Neurons and astrocytes, two principal cell types in the brain, coexist as an interdependent metabolic unit via the neurotransmitter glutamate. Disruption of this metabolic coupling would have widespread effects within the CNS, therefore it is hypothesized that ionizing radiation impairs glutamate transport and metabolism, and increases oxidative stress, ultimately impairing neuron-astrocyte coupling. We propose to investigate the mechanism and determine the impetus for radiation-induced neurotoxicity by measuring the temporal sequence …
Role Of Transient Receptor Potential Canonical-6 (Trpc6) Channel In Metastasis Of Glioblastoma Multiforme, Rajarajeshwari Venkataraman
Role Of Transient Receptor Potential Canonical-6 (Trpc6) Channel In Metastasis Of Glioblastoma Multiforme, Rajarajeshwari Venkataraman
Electronic Theses and Dissertations
Glioblastoma multiforme (GBM) is one of the extremely fatal brain tumors. The main reason that makes it so lethal is its capability to invade and spread to other parts of CNS producing secondary tumors. Among other factors hypoxia, reduced oxygen availability, is linked to higher metastatic potential of cancers. Hypoxia causes numerous changes in genome and proteome of the cell. These changes help a normal cell to adapt to nutritional deficiency, but the same changes can increase the malignancy and metastasis in tumor cells. Extensive research by a number of curious scientists reveal that various pathways involving numerous proteins cross-talk …

Evaluation Of The Efficacy Of Chloroplast-Derived Antigensagainst Malaria, Melissa Schreiber
Electronic Theses and Dissertations
Malaria is the most prevalent vector-borne parasitic disease worldwide and a major cause of death from infections. There is a great need to develop a low cost vaccine for malaria to control transmission of infection and impact of disease, due to the emergence of anti-malarial resistance. Two leading blood stage malarial vaccine candidates are the apical membrane antigen-1 (AMA-1) and the merozoite surface protein-1 (MSP-1). The aim of this project is to express malarial antigens in tobacco plants via plastid transformation and deliver them by subcutaneous or oral gavage of minimally processed transplastomic tissue to evaluate their efficacy to elicit …
