Chemophobia And The Relation To Names, Justin Crow

Undergraduate Research Conference

Chemophobia is a recently identified cultural phenomena where people are afraid of chemicals in their lives, whether "chemicals" are in their food, their medicines, vaccinations, and other products. An increasing amount of people have a concern about the risk associated with chemicals in their everyday life. Chemistry professionals find this a bit strange as Chemistry states that all matter is made up of chemicals. Chemistry has many systems of naming and understanding chemicals which can exclude people from understanding the risk or lack thereof attributed to materials that are common in daily life. This effect could be accentuated by educational …

Adhd Medication: To Medicate Or Not To Medicate?, Alyssa Henderson

Undergraduate Research Conference

Eleven percent of American children are diagnosed with at least one type of ADHD. That is 6.4 million children that are clinically diagnosed with the inability to focus attentively, restlessness, imbalanced mood swings and under-developed social skills. All of these lead to any learning environment being a daily battleground in the children both internally as well as externally. This is caused due to an under-activity in the frontal lobe of the child’s brain, which is responsible for their planning, motivation, social behavior and speech production. The symptoms associated with ADHD are currently being combated with the utilization of stimulants known …

Iron-Containing Nanoparticles For The Treatment Of Chrionic Biofilm Infections In Cystic Fibrosis, Leisha M. A. Martin

Nanoscience and Microsystems ETDs

Cystic fibrosis (CF) is the most common genetic disease resulting in the morbidity and mortality of Caucasian children and adults worldwide. Due to a genetic mutation resulting in malfunction of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, CF patients produce highly viscous mucus in their respiratory tract. This leads to impairment of the mucociliary clearance of inhaled microbes. In addition to reduced microbial clearance, anoxic environmental conditions in the lungs promote biofilm-mode growth of the pathogenic bacterial species Pseudomonas aeruginosa. Chronic infections of P. aeruginosa begin in early childhood and typically persist until respiratory failure and death result. The …

The Physiological Basis For Vitamin C As A Potential Treatment For Sepsis, Jennifer Johnston

BU Well

Accounting for one third of all hospital patient deaths in America, sepsis remains one of the most deadly and complicated conditions that healthcare providers treat. Septic shock, a progressed form of sepsis, is even more troublesome, as mortality rates typically fall between 50-72%. It has been proposed that administration of high doses of vitamin C could be an effective treatment for the condition due to the nutrient’s anti-stress and anti-shock properties. This investigation of the physiological reasoning for administering high doses of vitamin C evaluates the viability of its use in patients with septic shock.

Nanomedicine For The Treatment Of Non-Hodgkin Lymphoma, Tanvi Gandhi, B.Pharm

BU Well

Non-Hodgkin lymphoma, or NHL, is the predominant category of lymphoma. NHL is a type of lymphoid hematopoietic malignancy which approximately 70,000 Americans are diagnosed with annually, with the number of diagnoses growing annually. For decades, chemotherapy was the standard treatment of care, but since the discovery in 1997, monoclonal antibodies are increasingly used as an alternate form of therapy. Nonetheless, almost 20,000 Americans succumb to NHL annually, which highlights the translational gap between preclinical research and the market. Although a lot of progress has been made in therapy options by immunotherapy and combination chemotherapy, the ingenuity of nanomedicine may bridge …

The chemokine (C-C motif) chemokine ligand 18 (CCL18) is a structural homolog of CCL3 primarily produced by monocyte-derived cells with an M2 phenotype. Elevated levels of CCL18 have been observed in several diseases associated with malignancies and chronic inflammation. The role of CCL18 in Human Immunodeficiency Virus (HIV-1) infection remains unknown. We analyzed expression levels of T helper cell-mediated (TH2) chemokines CCL18, CCL17, and CCL22 by ELISA in plasma collected from HIV-1-infected and healthy donors. In HIV-1-infected individuals, plasma viral loads were monitored by NucliSense HIV-1 QT assay and T cell counts and expression of the activation marker CD38 were …

Synthesis And Antiproliferative Activities Of Conjugates Of Paclitaxel And Camptothecin With A Cyclic Cell-Penetrating Peptide, Naglaa Salem El-Sayed, Amir Nasrolahi Shirazi, Muhammad Imran Sajid, Shang Eun Park, Keykavous Parang, Rakesh Tiwari

Pharmacy Faculty Articles and Research

Cell-penetrating peptide [WR]5 has been previously shown to be an efficient molecular transporter for various hydrophilic and hydrophobic molecules. The peptide was synthesized using Fmoc/tBu solid-phase chemistry, and one arginine was replaced with one lysine to enable the conjugation with the anticancer drugs. Paclitaxel (PTX) was functionalized with an esterification reaction at the C20 hydroxyl group of PTX with glutaric anhydride and conjugated with the cyclic peptide [W(WR)4K(bAla)] in DMF to obtain the peptide-drug conjugate PTX1. Furthermore, camptothecin (CPT) was modified at the C(20)-hydroxyl group through the reaction with triphosgene. Then, it was conjugated with two functionalized cyclic peptides through …

Saturated Fatty Acid Activates T Cell Inflammation Through A Nicotinamide Nucleotide Transhydrogenase (Nnt)-Dependent Mechanism, Grace Mccambridge, Madhur Agrawal, Alanna Keady, Philip A. Kern, Hatice Hasturk, Barbara S. Nikolajczyk, Leena P. Bharath

Honors Senior Capstone Projects

Circulating fatty acids (FAs) increase with obesity and can drive mitochondrial damage and inflammation. Nicotinamide nucleotide transhydrogenase (NNT) is a mitochondrial protein that positively regulates nicotinamide adenine dinucleotide phosphate (NADPH), a key mediator of energy transduction and redox homeostasis. The role that NNT-regulated bioenergetics play in the inflammatory response of immune cells in obesity is untested. Our objective was to determine how free fatty acids (FFAs) regulate inflammation through impacts on mitochondria and redox homeostasis of peripheral blood mononuclear cells (PBMCs). PBMCs from lean subjects were activated with a T cell-specific stimulus in the presence or absence of generally pro-inflammatory …

Effects Of Ef-24 And Cisplatin On Cancer, Renal, And Auditory Cells, Denis Hodzic

Masters Theses & Specialist Projects

Cisplatin is a chemotherapy drug effective against several forms of cancer, but can also cause serious side-effects, including nephrotoxicity and ototoxicity. Curcumin, a natural plant compound, can increase cisplatin’s anti-cancer activity and counteract cisplatin’s deleterious effect on the auditory and renal systems. Unfortunately, curcumin exhibits poor bioavailability, which has promoted interest in the development of synthetic curcumin analogs (curcuminoids) that are soluble, target cancer, and do not cause side effects. This study investigated whether the curcuminoid (3E,5E)-3,5-bis[(2-fluorophenyl) methylene]-4-piperidinone (EF-24) increases the anti-cancer effects of cisplatin against a human ovarian cancer cell line (A2780) and its cisplatin-resistant counterpart (A2780cis), while preventing …

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue

Senior Theses

Phenylketonuria, now known as phenylalanine hydroxylase (PAH) deficiency, is a genetic disorder of metabolism affecting approximately one in every 15,000 infants born in the United States. Patients have nonfunctional PAH enzyme secondary to one or more genetic mutations. The enzyme deficit results in destructive supraphysiologic blood phenylalanine levels upon consumption of the essential dietary amino acid phenylalanine. Current standards of care mitigate signs and symptoms of the disorder, but do not approach a cure. The methods for creating a prototype pharmabiotic as an innovative treatment strategy for PAH deficiency are described herein.

DNA molecular cloning techniques were utilized to engineer …

Phytoene Accumulation In The Novel Microalga Chlorococcum Sp. Using The Pigment Synthesis Inhibitor Fluridone, Kelly Laje, Mark Seger, Barry Dungan, Peter Cooke, Juergen Polle, F. Omar Holguin

Publications and Research

Carotenoids are lipophilic pigments found in plants and algae, as well as some bacteria, archaea, and fungi that serve two functions—(1) as light harvesting molecules—primary carotenoids, and (2) as antioxidants, acting against reactive oxygen species–secondary carotenoids. Because of their strong antioxidant properties, they are also valuable for the development of anti-aging and photo-protective cosmetic applications. Of particular interest is the carotenoid phytoene, for its colorless and UV absorption characteristics. In this study, we targeted a reduction of phytoene desaturase (PDS) activity with the pigment-inhibiting herbicide 1-methyl-3-phenyl-5-[3- (trifluoromethyl)phenyl]pyridin-4-one (fluridone), which leads to the over-accumulation of phytoene in the recently characterized microalgal …

The Atpase Mechanism Of Uvra2 Reveals The Distinct Roles Of Proximal And Distal Atpase Sites In Nucleotide Excision Repair, Brandon C. Case, Silas Hartley, Memie Osuga, David Jeruzalmi, Manju M. Hingorani

Publications and Research

The UvrA2 dimer finds lesions in DNA and initiates nucleotide excision repair. Each UvrA monomer contains two essential ATPase sites: proximal (P) and distal (D). The manner whereby their activities enable UvrA2 damage sensing and response remains to be clarified. We report three key findings from the first pre-steady state kinetic analysis of each site. Absent DNA, a P2ATP-D2ADP species accumulates when the low-affinity proximal sites bind ATP and enable rapid ATP hydrolysis and phosphate release by the highaffinity distal sites, and ADP release limits catalytic turnover. Native DNA stimulates ATP hydrolysis by all four sites, causing UvrA2 to transition …

The Role Of Thyroglobulin In Thyroid Hormonogenesis, Cintia E. Citterio, Héctor M. Targovnik, Peter Arvan

Pharmacy Faculty Articles and Research

In humans, the thyroid hormones T₃ and T₄ are synthesized in the thyroid gland in a process that crucially involves the iodoglycoprotein thyroglobulin. The overall structure of thyroglobulin is conserved in all vertebrates. Upon thyroglobulin delivery from thyrocytes to the follicular lumen of the thyroid gland via the secretory pathway, multiple tyrosine residues can become iodinated to form mono-iodotyrosine (MIT) and/or di-iodotyrosine (DIT); however, selective tyrosine residues lead to preferential formation of T₄ and T₃ at distinct sites. T₄ formation involves oxidative coupling between two DIT side chains, and de novo T₃ formation involves …

Forensic Science Faculty Publications

Hyperthermia induced by 3,4-methylenedioxymethamphetamine (MDMA) can be life-threatening. Here, we investigate the role of the gut microbiome and TGR5 bile acid receptors in MDMA-mediated hyperthermia. Fourteen days prior to treatment with MDMA, male Sprague-Dawley rats were provided water or water treated with antibiotics. Animals that had received antibiotics displayed a reduction in gut bacteria and an attenuated hyperthermic response to MDMA. MDMA treated animals showed increased uncoupling protein 1 (UCP1)and TGR5 expression levels in brown adipose tissue and skeletal muscle while increased expression of UCP3 was observed only in skeletal muscle. Antibiotics prior to MDMA administration significantly blunted …

Updates On Epigenetic Alterations To Brca1: Chemosensitivities, Haley Blum

UNO Student Research and Creative Activity Fair

Breast cancer 1, early onset (BRCA1) is a human tumor suppressor gene encoding the BRCA1 protein that maintains genomic integrity. Molecular events may contribute to the loss of BRCA1 function, contributing to site specific tumorigenesis. Loss of BRCA1 function may arise from mutation or epigenetic events. Germline mutations of BRCA1 have been thoroughly implicated in heritable breast and ovarian cancers. More recently, sporadic breast cancer has been shown to be driven by epigenetic alterations to the BRCA1 promoter region, specifically methylation. Breast carcinomas that present with BRCA1 promoter methylation have been associated with triple negative breast cancers, as well …

Considerations For Implementing Precision Therapeutics For Children., Matthew J. Mclaughlin, Jonathan B. Wagner, Valentina Shakhnovich, Bruce Carleton, J Steven Leeder

Manuscripts, Articles, Book Chapters and Other Papers

Improving the utilization of pharmacologic agents in the pediatric population yields significant, perhaps life-long, benefits. Genetic factors related to the disposition of a medication or an alteration at the target receptor site contributes to the observed variability of exposure and response between individuals. An additional source of this variability specific to the pediatric population is ontogeny, where age-specific changes during development may require dose adjustments to obtain the same levels of drug exposure and response. With significant improvements in characterizing both the ontogeny and genetic contributions of drug metabolizing enzymes, the time is right to begin placing more emphasis on …
