Safety Of Saccharomyces Boulardii (Florastor) In Solid Organ Transplant Patients, Nicole Marie Dores

Undergraduate Honors Thesis Collection

Probiotics have been promoted for use in many gastrointestinal ailments. Most studies find probiotics safe for human use, reporting no severe adverse effects. However, probiotics are live microorganisms and thus have the potential to cause infection. Transplant recipients are considered at high risk for infectious complications from probiotics due to the immunosuppressive medications used to prevent organ rejection. Nonetheless, clinicians are currently utilizing probiotics in the transplant population, due to their benefit in gastrointestinal disorders, particularly recurrent Clostridium difficile. Limited knowledge and paucity of prospective trials in this patient population demands the need for completion of studies to identify the …

Over-The-Counter Non-Steroidal Anti-Anflammatory Drugs In Adolescent Athletes, Anna Christine Parada

Undergraduate Honors Thesis Collection

Non-steroidal anti-inflammatory drugs (NSAIDs) are common medications used by the general population due their anti-inflammatory and analgesic properties. These are especially popular in athletes since they are not prohibited in many rules of athletic competition. Over-the-counter (OTC) NSAIDs comprise several drugs that may be purchased without a prescription. These are often over-utilized by the general population due to their accessibility and relatively low cost. The unsuspecting victims are the children, especially adolescent athletes, who deem OTC NSAIDs safe without realizing the potential adverse effects of inappropriate consumption of these medications. This article reviews the approved indications and side effects of …

Synthesis And Biological Evaluation Of Second Generation Anibamine Analogues As Novel Anti-Prostate Cancer Agents, Shilpa Singh

Theses and Dissertations

Prostate cancer is the most prevalent non-cutaneous cancer among men. Since the 19th century when Virchow first introduced the concept of inflammation in cancer, chemokines and their receptors have garnered a lot of interest. Chemokine receptor CCR5 has been especially implicated in many disease states and recently found to be over expressed in prostate cancer cell lines. Anibamine, a natural CCR5 antagonist discovered in 2004, has been found to have significant anti-prostate cancer activity at micromolar level. To optimize this compound and also discover a novel pharmacophore, exploration of the original structure was carried out. Significant modifications were made to …

Generating Induced Pluripotent Stem Cells From Human Fibroblast Utilizing Controlled Expression Of Transcription Factors, Ju-Sung Song

Honors Scholar Theses

Human Embryonic stem cells (hESCs) represent a pluripotent cell population derived from the inner cell mass (ICM) of the blastocyst stage of the developing embryo. Ethical concerns have been raised regarding the derivation process, as the procedure ultimately results in the destruction of the embryos. Recently, alternative approach has been devised that encompasses reprogramming of terminally differentiated cells into an hESC-like state. This process relies on the over-expression of four pluripotency-associated factors, and successfully reprogrammed cells are termed induced pluripotent stem cells (iPSCs). These cells hold great promise for the use in future cell-based therapeutics such as evaluating drug induced …

Selectivity Of The Ubiquitin-Binding Modules, Simin Rahighi, Ivan Dikic

Pharmacy Faculty Articles and Research

Ubiquitin-binding modules are constituents of cellular proteins that mediate the effects of ubiquitylation by making transient, non-covalent interactions with ubiquitin molecules. While some ubiquitin- binding modules bind single ubiquitin moieties, others are selective for specific ubiquitin chains of different linkage types and lengths. In recent years, functions of ubiquitin chains that are polymerized through their Lys or N-terminal Met (i.e. linear chains) residues have been linked to a variety of cellular processes. Selectivity of ubiquitin-binding modules for different ubiquitin chain types appears as a key to the distinct regulatory consequences during protein quality control pathways, receptor endocytosis, gene transcription, signaling …

Mahurin Honors College Capstone Experience/Thesis Projects

Xylose is a natural monosaccharide found in biomass such as straw, pecan shells, cottonseed hulls, and corncobs. Using this monosaccharide, we report the green synthesis and characterization of biocompatible, biodegradable xylose encapsulated gold nanoparticles (Xyl-GNPs) with potential antibacterial activity. GNPs were synthesized using the bioreduction property of xylose on the chloroaurate anions in an aqueous solution at room temperature and at atmospheric pressure. The characterization of synthesized GNPs was examined by UV-vis spectroscopy; transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS) and fourier transform infrared spectroscopy (FTIR). Results indicate that the particles were stable; near spherical in shape with an …

Investigations Of Pharmacokinetic Challenges In Premature Infants, Yi Zhang

Theses and Dissertations (ETD)

Premature infants (gestational age less than 37 weeks) are considered a vulnerable patient population due to their immaturity at birth. Currently, off-label prescribing is common in younger pediatric populations, especially in premature neonates and infants, which is a primary group receiving intensive care. Unique pharmacokinetic (PK) challenges—such as limited blood volume and frequency of blood sample collections, rapid growth and continuous developmental changes, complexity of pediatric studies as well as scientific, practical, and ethical concerns— lead to the current lack of PK information and empirical dosing in premature neonates and infants. In this research, several approaches were investigated to overcome …

Development Of Co-Processed Plasticized Cellulose Acetate For Sustained Release Matrix Tablets, Yinqi Zhou

Theses and Dissertations (ETD)

Cellulose Acetate (CA) is a polymer extensively used in pharmaceutical applications. Because of the hydrophobic nature and good film properties of CA, it is a good polymer candidate for sustained release matrix tablets. Sustained release matrix tablets of cellulose acetate can be prepared by direct compression or wet granulation methods. However, previous studies showed that a large amount of CA was required to achieve the desired sustained release profile for a sparingly soluble drug and it was difficult to formulate a highly water soluble drug by using CA as the retarding agent. Some studies concluded that CA is very sensitive …

Preclinical Study Of Potential Antiglioma Novel Tetrahydroisoquinoline Analogs: Pharmacokinetics And Mechanism Of Action, Fei Ma

Theses and Dissertations (ETD)

Gliomas, the tumors of glial cells, account for 80% of primary malignant brain tumors. In 2011, there were about 18,300 new cases of maligant gliomas in the United States alone. Patients with glioblastoma multiforme or anaplastic astrocytoma, the two major types of malignant gliomas, have a median survival of 14 months or 2 to 3 years, respectively. Therefore novel treatments for malignant glioma are urgently needed.

Approaches In The Treatment Of Parkinson's Disease : A Focus On Stem Cell-Based Therapies., Tareq Al-Maqtari 1979-

Electronic Theses and Dissertations

Parkinson's disease (PD) is a hypokinetic movement disorder resulting from the progressive neurodegeneration of the dopaminergic nigrostriatal system in the brain and the resulting imbalance between dopamine and acetylcholine in the basal ganglia motor circuitry. Although drug-based therapy approaches have shown dramatic symptomatic improvement in patients, they do not halt the progressive nature of the disease and their long-term use is associated with distressing adverse side effects. Consequently, several studies have aimed at discovering effective non-pharmacological strategies to reduce or to eliminate the need for drugs and possibly to halt or to reverse the neurodegenerative process in PD. Surgical deep …

The Histone Deacetylase Inhibitor, Ms-275, Sensitizes Metastatic Osteosarcoma To Fasl-Induced Cell Death: A Role For C-Flip, Krithi R. Bindal

Dissertations and Theses (Open Access)

The purpose of this study was to determine the effects of the histone deacetylase inhibitor, MS-275, on the Fas signaling pathway and susceptibility of osteosarcoma (OS) to Fas ligand (FasL)-induced cell death. OS metastasizes almost exclusively to the lungs. We have shown that Fas expression in OS cells is inversely correlated with their metastatic potential. Fas⁺ cells are rapidly eliminated when they enter the lungs via interaction with FasL, which is constitutively expressed in the lungs. Fas^- OS cells escape this FasL-induced apoptosis and survive in the lung microenvironment. Moreover, upregulation of Fas in established OS lung metastases …

Archaeosomes And Tetraether Lipid Liposome, Hans-Joachim Freisleben

Majalah Ilmu Kefarmasian

Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up the majority of total membrane lipids. Archaeal lipids are able to form stable liposomal structures, both from membrane factions, mainly the polar membrane fraction, i.e. archaeosomes, or from highly purified TEL (tetraether lipid liposomes). Liposomes of the main polar lipid (MPL) from thermoacidophilic archaeon Ihermoplasma acidophilum were thoroughly inevstigated. Archaeosomes and TEL liposomes exhibit extremely low proton permeability and high stability at …
