Ricin B Chain-Insulin Fusion Protein Immunomodulation Of Type 1 Diabetes, James Edward Carter Iii
Ricin B Chain-Insulin Fusion Protein Immunomodulation Of Type 1 Diabetes, James Edward Carter Iii
Loma Linda University Electronic Theses, Dissertations & Projects
Type 1 diabetes mellitus (T1D) is a debilitating chronic inflammatory disease of the insulin-producing pancreatic islet β-cells that results from a combination of genetic and environmental factors. Attempts to suppress Th1-mediated autoimmune diseases such as T1D by mucosal delivery of autoantigens for immunotolerization have yielded only partial success. Attainment of satisfactory levels of sustained immunological tolerance remains to be accomplished. To restore self-tolerance requires delivery of sufficient amounts of autoantigen to stimulate regulatory T helper cells that function to survey the gut and induce tolerance to consumed antigens such as food. Oral delivery of autoantigens has previously been shown to …
Fetal Programming By Nicotine Increases Cardiac Susceptibility To Ischemic Injury, Jennifer Charlotte Alexie Lawrence
Fetal Programming By Nicotine Increases Cardiac Susceptibility To Ischemic Injury, Jennifer Charlotte Alexie Lawrence
Loma Linda University Electronic Theses, Dissertations & Projects
Fetal programming is the area of study that focuses on the prenatal origins of adult onset disorders. Previous studies have associated an adverse prenatal environment with the onset of physiologic and metabolic diseases during adulthood. Fetal malnutrition, hypoxia, and exposure to drugs - such as cocaine and nicotine - have been associated with adult disease states. Cigarette smoking is the number one cause of preventable death in the developed world. Among the many dangerous chemicals found in tobacco products is nicotine, the compound responsible for the addictive nature of tobacco use. Nicotine use during pregnancy is a known cause of …
Thioester Hydrolysis Reactivity Of Metal Complexes, James Justin Danford
Thioester Hydrolysis Reactivity Of Metal Complexes, James Justin Danford
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Glyoxalase II is one of two metalloenzymes found in the glyoxalase pathway and is responsible for catalyzing the hydrolysis of a thioester substrate. Its bimetallic active site is found to contain a variety of metal combinations, including Fe(III)Zn(II). A recent report indicates that human glyoxalase II, while containing a Fe(II)Zn(II) center, is catalytically active as a mononuclear Zn(II) enzyme. Detailed mechanistic studies of glyoxalase II enzymes are limited due to uncertainty in the metal ion content of recombinantly prepared samples. The research presented in this thesis is focused on gaining mechanistic insight into thioester hydrolysis promoted by well-characterized metal complexes …
Discovery Of Quinic Acid Derivatives As Oral Anti-Inflammatory Agents, Kui Zeng
Discovery Of Quinic Acid Derivatives As Oral Anti-Inflammatory Agents, Kui Zeng
Theses and Dissertations (ETD)
Quinic acid (QA) esters found in hot water extracts of Uncaria tomentosa (a.k.a. Cat’s claw) exert anti-inflammatory activity through mechanisms involving inhibition of the pro-inflammatory transcription factor nuclear factor kappa B (NF-κB). Herein, we described the synthesis and biological testing of novel QA derivatives. Inhibition of NF-κB was assessed using A549 (Type II alveolar epithelial-like) cells that stably express a secreted alkaline phosphatase (SEAP) reporter driven by an NF-κB response element. A549- NF-κB cells were stimulated with TNF-α (10 ng/mL) in the presence or absence of QA derivative for 18 hours followed by measurement of SEAP activity. Amide substitution at …
Characterization And Optimization Of Antigen-Specific T Cell Responses During Ex Vivo Expansion Of Melanoma Tumor-Infiltrating Lymphocytes, Yufeng Li
Dissertations & Theses (Open Access)
Treatment of metastatic melanoma with tumor reactive T cells (adoptive T cell therapy, ACT) is a promising approach associated with a high clinical response rate. However, further optimization of this treatment modality is required to increase the clinical response after this therapy. ACT in melanoma involves an initial phase (pre-REP) of tumor-infiltrating lymphocyte (TIL) expansion ex vivo from tumor isolates followed by a second phase, “rapid expansion protocol” (REP) generating the billions of cells used as the TIL infusion product. The main question addressed in this thesis was how the currently used REP affected the responsiveness of the CD8+ T …
Evidence And Impact Of Expectancies Associated With Psychotropic Medication Reductions In Persons With Mental Retardation, Christopher S. Baglio
Evidence And Impact Of Expectancies Associated With Psychotropic Medication Reductions In Persons With Mental Retardation, Christopher S. Baglio
Ed.D. Dissertations
This study was an attempt to understand the presence and impact of staff expectancies related to psychotropic medication reductions conducted with persons diagnosed with mental retardation. Within a state operated developmental center in the Midwest, results indicated that direct support staff overwhelmingly expected individuals to get worse following such a reduction. These expectancies significantly impacted data recording practice leading to discrepant elevations reported by staff expecting deterioration. Finally, while written communication about planned psychotropic medication reductions did not appear to elevate data recording as was hypothesized, reductions were associated with increases in both behaviors and psychiatric symptoms. This study has …
Cip4 And Src In Promoting The Migration And Invasion Of Breast Cancers, Christina S. Pichot
Cip4 And Src In Promoting The Migration And Invasion Of Breast Cancers, Christina S. Pichot
Dissertations & Theses (Open Access)
Cellular invasion represents a critical early step in the metastatic cascade, and many proteins have been identified as part of an “invasive signature.” The non-receptor tyrosine kinase Src is commonly upregulated in breast cancers, often in conjunction with overexpression of EGFR. Signaling from this pathway stimulates cell proliferation, migration, and invasion and frequently involves proteins that regulate the cytoskeleton. My data demonstrates that inhibition of Src, using the small-molecule inhibitor dasatinib, impairs cellular migration and invasion. Furthermore, Src inhibition sensitizes the cells to the effects of the chemotherapeutic doxorubicin resulting in dramatic, synergistic inhibition of proliferation with combination treatments. The …

Protein Evolution Via Amino Acid And Codon Elimination, Lise Goltermann, Marie Sofie Yoo Larsen, Ranat Banerjee, Andreas C. Joerger, Michael Ibba, Thomas Bentin
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Background
Global residue-specific amino acid mutagenesis can provide important biological insight and generate proteins with altered properties, but at the risk of protein misfolding. Further, targeted libraries are usually restricted to a handful of amino acids because there is an exponential correlation between the number of residues randomized and the size of the resulting ensemble. Using GFP as the model protein, we present a strategy, termed protein evolution via amino acid and codon elimination, through which simplified, native-like polypeptides encoded by a reduced genetic code were obtained via screening of reduced-size ensembles.
Methodology/Principal Findings
The strategy involves combining a sequential …

How The Sequence Of A Gene Can Tune Its Translation, Kurt Fredrick, Michael Ibba
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Sixty-one codons specify 20 amino acids, offering cells many options for encoding a polypeptide sequence. Two new studies (Cannarrozzi et al., 2010, Tuller et al., 2010) now foster the idea that patterns of codon usage can control ribosome speed, fine-tuning translation to increase the efficiency of protein synthesis.
The Effects Of Cocaine And Ecstasy On Cardiac Myocytes And The Intact Myocardium, David A. Tiangco
The Effects Of Cocaine And Ecstasy On Cardiac Myocytes And The Intact Myocardium, David A. Tiangco
Theses and Dissertations in Biomedical Sciences
Cocaine and ecstasy are widely used illicit drugs. Both drugs have undergone intense scrutiny as information regarding their side-effects has become available. One important yet incomplete area of investigation pertains to their effects on the heart. The purpose of the current studies was to test the hypothesis that exposure to cocaine or ecstasy will adversely affect cellular homeostasis and normal heart function. Cultured cardiac myocytes (H9c2) and New Zealand White rabbits (Oryctolagus cuniculus) were used to measure the responses to various concentrations of cocaine or ecstasy at both the cellular and intact organ system levels. We observed that cocaine and …

Distribution Of Allatostatin C-Like Immunoreactivity In The Central Nervous System Of The Copepod Crustacean Calanus Finmarchicus, Caroline H. Wilson, Andrew E. Christie
Health Sciences and Kinesiology Faculty Articles
The C-type allatostatins (C-ASTs) are a family of highly pleiotropic arthropod neuropeptides. In crustaceans, transcriptomic/mass spectral studies have identified C-ASTs in the nervous systems of many species; the cellular distributions of these peptides remain unknown. Here, the distribution of C-AST was mapped in the nervous system of the copepod Calanus finmarchicus, the major contributor to the North Atlantic’s zooplanktonic biomass; C-AST-immunopositive neurons were identified in the protocerebrum, in several peripheral ganglia associated with feeding appendages, and in the ganglia controlling the swimming legs, with immunopositive axons present throughout the ventral nerve cord. In addition, axons innervating the dorsal longitudinal …

Interconversion Of The Specificities Of Human Lysosomal Enzymes, Ivan B. Tomasic
Interconversion Of The Specificities Of Human Lysosomal Enzymes, Ivan B. Tomasic
Masters Theses 1911 - February 2014
Fabry disease (FD) is an X-linked recessive lysosomal storage disorder (LSD) known to affect approximately 1 in every 40,000 males, and a smaller number of females. FD results from a deficiency of functional α-galactosidase (α-GAL), which leads to the accumulation of terminally α-galactosylated substrates in the lysosome. The predominant treatment is Enzyme Replacement Therapy (ERT), requiring the regular infusion of recombinant human α-GAL. More than half of individuals receiving ERT experience a range of adverse infusion reactions, and it has been reported that as many as 88% of patients receiving ERT develop neutralizing IgG antibodies against the drug.

Scholarship and Professional Work – COPHS
Chromatin remodeling is an essential part of transcription initiation. We show that at heat shock gene promoters functional interactions between individual ATP-dependent chromatin remodeling complexes play critical role in both nucleosome displacement and Pol II recruitment. Using HSP12, HSP82 and SSA4 gene promoters as reporters, we demonstrated that while inactivation of SNF2, a critical ATPase of the SWI/SNF complex, primarily affects the HSP12 promoter, depletion of STH1- a SNF2 homolog from the RSC complex reduces histone displacement and abolishes the Pol II recruitment at all three promoters. From these results, we conclude that redundancy between SWI/SNF and RSC complexes …

The immunotoxicity of three generations of polyamidoamine (PAMAM) dendrimers (G-4, G-5 and G-6) was evaluated in mouse macrophage cells in vitro. Using the Alamar blue and MTT assays, a generation dependent cytotoxicity of the PAMAM dendrimers was found whereby G-6 > G-5 > G-4. The toxic response of the PAMAM dendrimers correlated well with the number of surface primary amino groups, with increasing number resulting in an increase in toxic response. An assessment of intracellular ROS generation by the PAMAM dendrimers was performed by measuring the increased fluorescence as a result of intracellular oxidation of Carboxy H2DCFDA to DCF both quantitatively using …
Paraoxonase 1 Activity As A Predictor Of Cardiovascular Disease In Type 2 Diabetes, Rozaida @ Poh Yuen Ying
Paraoxonase 1 Activity As A Predictor Of Cardiovascular Disease In Type 2 Diabetes, Rozaida @ Poh Yuen Ying
Rozaida @ Poh Yuen Ying
The role of paraoxonase 1 in cardiovascular disease complications in type 2 diabetes mellitus is not fully understood. We studied paraoxonase activity towards paraoxon in 188 non-diabetic and 140 diabetic subjects using general linear models and univariate analysis. Adjusting for age revealed a reduction in activity towards paraoxon was associated with a significant increase in risk (p=0.023) for cardiovascular disease complications in diabetic patients. Multivariate analysis of two plasma measures of paraoxonase activity using paraoxon and diazoxon also showed reduced paraoxonase activity towards paraoxon was associated with a significant increase in risk (p=0.045) for cardiovascular disease complications in diabetic patients. …

"A Cage Of Ovulating Females" : Mary Breckinridge And The Politics Of Contraception In Rural Appalachia, Dana Allen Johnson
Theses, Dissertations and Capstones
Mary Breckinridge and the Frontier Nursing Service have been the focus of intense scholarly effort over the last twenty years. Scholarship on Mary Breckinridge has centered on her healthcare reform work in Appalachia and its effects on the local residents and culture. This thesis examines the oral contraceptive trial that the FNS performed in Leslie County in the late 1950s and early 1960s. Although Breckinridge and the FNS maintained a restrictive contraceptive stance, they paradoxically permitted the contraceptive trial to be conducted on their patients in Leslie County. The decision to participate in the contraceptive trial resulted from a complex …

For the early detection of prostate cancer, the analysis of the Prostate-specific antigen (PSA) in serum is currently the most popular approach. However, previous studies show that 15% of men have prostate cancer even their PSA concentrations are low. MALDI Mass Spectrometry (MS) proves to be a better technology to discover molecular tools for early cancer detection. The molecular tools or peptides are termed as biomarkers. Using MALDI MS data from prostate tissue samples, prostate cancer biomarkers can be identified by searching for molecular or molecular combination that can differentiate cancer tissue regions from normal ones. Cancer tissue regions are …

Differential Control Of Tgm2 Expression By Oestrogen Receptor/Serms., Damian Lally
Masters
Breast cancer is a malignancy of the epithelial cells comprising the mammary gland. As the ER is necessary for the growth of pproximately 70% of breast cancers, pharmaceutical efforts have focused on uncovering modulators of the ERα such as antiestrogens and Selective Oestrogen Receptor Modulator (SERMs). SERMs differ from pure ER antagonists in their capacity to display tissue-selective and C promoter dependent agonist-antagonist activities. Tamoxifen (TAM) is a SERM that is used in the treatment of hormonally responsive breast cancer. TAM is the most commonly used treatment for patients with ERα positive breast cancer. In this study we examined the …

Pharmacy Faculty Articles and Research
The plasma and tissue disposition of two novel dextran prodrugs of methylprednisolone (MP) containing one (DMP-1) or five (DMP-5) amino acids as linkers were studied in rats. Single 5-mg/kg doses (MP equivalent) of each prodrug or MP were administered intravenously, and blood and tissue samples were collected. Prodrug and drug concentrations were quantitated using HPLC, and noncompartmental pharmacokinetic parameters were estimated. Whereas conjugation of MP with dextran in both prodrugs substantially decreased the clearance of the drug by ∼200-fold, the accumulations of the drug in the liver, spleen, and kidneys were significantly increased by conjugation. However, the extent of accumulation …

We investigated the contractile roles of M2 and M3 muscarinic receptors in urinary bladder from streptozotocin-treated mice. Wild-type and M2 muscarinic receptor knockout (M2 KO) mice were given a single injection of vehicle or streptozotocin (125 mg kg−1) 2–24 weeks prior to bladder assays. The effect of forskolin on contractions elicited to the muscarinic agonist, oxotremorine-M, was measured in isolated urinary bladder (intact or denuded of urothelium). Denuded urinary bladder from vehicle-treated wild-type and M2 KO mice exhibited similar contractile responses to oxotremorine-M, when contraction was normalized relative to that elicited by KCl (50 mM). Eight to 9 weeks after …

The effect of the plant-derived nonpsychotropic cannabinoid, cannabidiol (CBD), on the function of hydroxytryptamine (5-HT)3A receptors expressed in Xenopus laevis oocytes was investigated using two-electrode voltage-clamp techniques. CBD reversibly inhibited 5-HT (1 μM)-evoked currents in a concentration-dependent manner (IC50 = 0.6 μM). CBD (1 μM) did not alter specific binding of the 5-HT3A antagonist [3H]3-(5-methyl-1H-imidazol-4-yl)-1-(1-methylindol-3-yl)propan-1-one (GR65630), in oocytes expressing 5-HT3A receptors. In the presence of 1 μM CBD, the maximal 5-HT-induced currents were also inhibited. The EC50 values were 1.2 and 1.4 μM, in the absence and presence of CBD, indicating that CBD acts as a noncompetitive antagonist of 5-HT3 …

Folic Acid And Neural Tube Defects, Rachel Leah Feinstein
The Science Journal of the Lander College of Arts and Sciences
The following is an excerpt of this article: Neural tube defects (NTD) are the most common types of birth defects. Research shows that folic acid taken periconceptionally greatly reduces the risk of having a NTD affected child. This paper will explain the role that folate plays in the metabolism, specifically in synthesizing methionine. It will bring evidence to show that methionine is crucial for normal neural tube development. In addition, it will explore the genetic factor involved in folate metabolism and possible folate deficiency.
