The Effect Of Alpha-Cyclodextrin On Acute Blood Lipid And Glycemic Responses To A Fat Containg Meal, Evan Neil Fletcher Jan 2013

The Effect Of Alpha-Cyclodextrin On Acute Blood Lipid And Glycemic Responses To A Fat Containg Meal, Evan Neil Fletcher

Wayne State University Theses

Obesity and hyperlipidemia have become major concerns in the United States over the past 30 years. Alpha-Cyclodextrin (á-CD), a naturally occurring soluble dietary fiber, has been shown to reduce dietary fat absorption and improve blood lipid levels in an animal model (mouse and rat) and in human studies. In the current double blind study, 34 healthy male and female participants were recruited to test if á-CD had any acute effect on blood lipid and glycemic responses to a fat containing meal. The participants received the á-CD on one occasion and a placebo the other to determine if there was any …


Oligospermines For Non-Viral Sirna Delivery, Maha Elsayed Jan 2013

Oligospermines For Non-Viral Sirna Delivery, Maha Elsayed

Wayne State University Theses

In this thesis, delivery systems for siRNA delivery are introduced with special attention to non-viral vectors. Many successful vectors used in vivo were reviewed. Our work focused on the effect of different architectures of oligospermine polmers on their suitability for siRNA delivery in lung cancer cells. Different archituctures showed different polyplex structures and variable transfection efficiencies. Moreover, we presented a review on nanoimprint lithography techniques with an outlook on possible biological applications in the field of gene and drug delivery.


Novel Inhibitors Of The Bacterial De Novo Purine Biosynthesis Enzymes, N5-Carboxyaminoimidazole Ribonucleotide Synthetase And Mutase, Maria V. Fawaz Jan 2012

Novel Inhibitors Of The Bacterial De Novo Purine Biosynthesis Enzymes, N5-Carboxyaminoimidazole Ribonucleotide Synthetase And Mutase, Maria V. Fawaz

Wayne State University Theses

Antibiotic resistance has seen a significant increase during the past decade. The increasing frequency of the drug-resistant bacterial infections has amplified the need for novel antimicrobial agents. De novo purine biosynthesis is one area that has great potential for antibacterial drug development because this pathway is different in microorganisms versus humans. The difference in the pathway is centered on the synthesis and utilization of the purine intermediate N5-carboxy-5-aminoimidazole ribonucleotide (N5-CAIR). Previous studies have shown that N5-CAIR is a key intermediate in purine biosynthesis in bacteria, yeast and fungi, but not in humans. N5 …


Novel Inhibitors Of Lysine Specific Demethylase 1 As Epigenetic Modulators, Michael Crowley Jan 2011

Novel Inhibitors Of Lysine Specific Demethylase 1 As Epigenetic Modulators, Michael Crowley

Wayne State University Theses

The recently discovered enzyme lysine-specific demethylase 1 (LSD1) plays an important role in the epigenetic control of gene expression, and aberrant gene silencing secondary to LSD1 over expression is thought to contribute to the development of cancer. We recently reported a series of (bis)guanidines and (bis)biguanides that are potent inhibitors of LSD1, and induce the re-expression of aberrantly silenced tumor suppressor genes in tumor cells in vitro. We now report a new series of isosteres that are also potent inhibitors of LSD1. These compounds induce increases in methylation at the histone 3 lysine 4 (H3K4) chromatin mark, a specific target …
