Unlocking The Mysteries Of Weed And Mexico, Eddy Martinez

Capstones

An American biotech firm named Phylos Bioscience is interested in entering the Mexican marijuana market once it legalizes. Before it can do that, it must deal with the Mexican government and a conservative society.

Synthesis And Characterization Of Cytocompatible Sponge-Mimetic Scaffolds And Biomedical Polymers, Kamia Punia

Dissertations, Theses, and Capstone Projects

This dissertation describes the novel synthetic methodologies towards: a) protein/polysaccharide intercalated sponge-mimetic scaffolds for 3D cell culture, b) peptide-mimetic cationic amphiphilic antibacterial polymers, and c) bioactive Poly(DL-lactide-co-glycolide) (PLGA) nanofibers by solution blow spinning for the treatment of cancer and traumatic wound care.

The classic “chemical garden” experiment is reconstructed to produce protein/polysaccharide (ingredients of cyanobacterial origin) intercalated silicate-phosphate tubules that resemble tubular sponges. The constructs were synthesized by seeding calcium chloride into a solution of sodium silicate-potassium phosphate and gelatin/polysaccharides. The morphology and composition of sponge-mimetic tubules were analyzed by a battery of techniques. Bioconjugation and coating protocols were developed …

Zolpidem Facilitated Sexual Assaults: A Hair Method Validation, Danielle N. Chasworth

Student Theses

A liquid chromatography tandem mass spectrometry (LC-MSMS) method was developed and validated to detect for the presence of zolpidem in human hair samples. Zolpidem is a sedative hypnotic whose adverse effects make it a common drug found in drug facilitated crimes (DFC). It is important to be able to detect and quantitate the drug after a long period of time due to the victim’s delayed reporting of the crime. Hair’s long window of detection makes it a useful matrix for DFC investigations. The linear range of the assay was targeted at 2 pg/mg to 1,000 pg/mg and experiments designed to …

Catalyzed And Uncatalyzed Modifications Of Nucleosides, Synthesis Of Hippadine, And Deuterated 1,2,3-Triazoles, Hari K. Akula

Dissertations, Theses, and Capstone Projects

The C4 amide carbonyl of O-t-butyldimethylsilyl-protected thymidine, 2’-deoxyuridine, and 3’-azidothymidine (AZT) was activated by reaction with (benzotriazol-1-yloxy)tris(dimethylamino) phosphonium hexafluorophosphate (BOP) and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in THF as solvent. This led to the formation of corresponding O⁴-(benzotriazol-1-yl) derivatives, which are reactive intermediates. Substitution at the C4 position was then carried out by reactions with alkyl and aryl amines, and thiols. Typically, reactions were conducted as a two-step, one-pot transformation, and also as a one-step conversion. After examining the reactions, the formation of 1-(4-pyrimidinyl)-1H-benzotriazole-3-oxide derivatives from the pyrimidine nucleosides was identified. However, these too underwent conversion to …

Microrna 1207-3p In Prostate Cancer, Dibash Das

Dissertations, Theses, and Capstone Projects

Prostate cancer (PCa) is the most commonly diagnosed male cancer and the second leading cause of cancer-related death for men in the United States. Understanding the molecular mechanisms involved in progression from the asymptomatic androgen-dependent PCa to the lethal castration resistant prostate cancer (CRPC) is a major challenge. MicroRNAs (miRNAs), are known to be dysregulated in PCa. MicroRNA-1207-3p (miR-1207-3p) is encoded by the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of miR-1207-3p in PCa is unclear. We have discovered that miR-1207-3p is significantly underexpressed in PCa cell lines …

New Dyes For Cancer Theranostics, Waqar Rizvi

Dissertations, Theses, and Capstone Projects

Porphyrinoids are robust heterocyclic dyes studied extensively for applications in medicine and as photonic materials because of their tunable photophysical properties, diverse means of modifying the periphery, and the ability to chelate most transition metals. Commercial applications include phthalocyanine dyes in optical discs, porphyrins in photodynamic therapy, and as oxygen sensors. Most applications of these dyes require exocyclic moieties to improve solubility, target disease, modulate photophysical properties, or direct self-organization into architectures with desired photonic properties. The synthesis of the porphyrinoid depends on the desired application, but the de novo synthesis often involves several steps, is time consuming, and results …

Bacterial Lps At The Immune Modulating Component In Juzen-Taiho-To, Diego Montenegro

Dissertations, Theses, and Capstone Projects

Juzen-taiho-to (JTT) is an immune-boosting herbal formulation with an ideal balance of safety and efficacy. For example, JTT is clinically used in Japan to stimulate the immunological functions of cancer patients undergoing chemotherapy and radiation. Although the clinical effects of JTT are recognized, the active compounds and mechanism of action are unknown. The studies conducted previously in our laboratory associated several phytosterols and plant glycolipids with the potent immunostimulatory activity of JTT: namely, β-sitosteryl β-D-glucoside (BSSG), glucocerebroside (GluCer), digalactosyldiacylglycerol (DGDG) and monogalactosyldiacylglycerol (MGDG). However, these compounds, when further purified, exhibited little or no immunostimulatory activity. This suggested that the immunostimulatory …
