Racemic and Enantioselective Synthesis of Cavicularin

Creator:: Zhao, Peng
Abstract:: This dissertation describes the racemic and enantioselective synthesis cavicularin. Cavicularin is a macrocyclic bisbibenzyls family member natural product. It has been an attractive synthetic target due to its intriguing structure: the macrocyclic core imparts sufficient strain on the system to force one benzene rings to adopt a boat-shaped conformation, out...

Total Synthesis of (+)-Cavicularin: The Pyrone Diels–Alder Reaction in Enantioselective Cyclophane Synthesis

Creator:: Zhao, Peng and Beaudry, Christopher M.
Abstract:: A pyrone Diels–Alder strategy was developed for the synthesis of the cyclophane natural product, cavicularin. The strategy uses a vinyl sulfone as an alkyne equivalent dienophile. An enantioselective variant delivered (+)-cavicularin.

Investigation of Eco-friendly, Bio-based Methods to Produce High Quality and Water-resistant Apple Pomace Biocomposites Using Molded Pulp Technology

Creator:: Lang, Clara V.
Abstract:: The overall goal of this study was to utilize apple pomace, the byproduct from juice processing, as a renewable source of fiber to create sustainable packaging using molded pulp technology. The goal was accomplished through two studies: 1) to modify apple pomace fibers for increasing relative cellulose composition and improving...

Investigation of film forming properties of beta-chitosan from jumbo squid pens (Dosidicus gigas) and improvement of water solubility of beta-chitosan, Investigation of film forming properties of β-chitosan from jumbo squid pens (Dosidicus gigas) and improvement of water solubility of β-chitosan

Creator:: Chen, Jeremy L.
Abstract:: The objectives of this project were to investigate the critical factors impacting the physicochemical and antibacterial properties of β-chitosan based films derived from jumbo squid (Dosidicus gigas) pens, and to evaluate the feasibility of improving water solubility of β-chitosan through Maillard reaction. The studies examined the effect of molecular weight...

New development of beta-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties, New development of β-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties

Creator:: Jung, Jooyeoun
Abstract:: β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...

Pixel- and Frame-level Video Labeling using Spatial and Temporal Convolutional Networks

Creator:: Lei, Peng
Abstract:: This dissertation addresses the problem of video labeling at both the frame and pixel levels using deep learning. For pixel-level video labeling, we have studied two problems: i) Spatiotemporal video segmentation and ii) Boundary detection and boundary flow estimation. For the problem of spatiotemporal video segmentation, we have developed recurrent...

Flexible dual TCP/UDP streaming for H.264 HD video over WLANs

Creator:: Zhao, Jing
Abstract:: High Definition video streaming over WLANs faces many challenges because video data requires not only data integrity but also frames have strict playout deadline. Traditional streaming methods that rely solely on either UDP or TCP have difficulties meeting both requirements because UDP incurs packet loss while TCP incurs delay. This...

Alkali or acid induced changes in structure, moisture absorption ability and deacetylating reaction of β-chitin extracted from jumbo squid (Dosidicus gigas) pens

Creator:: Jung, Jooyeoun and Zhao, Yanyun
Abstract:: Alkali or acid-induced structural modifications in β-chitin from squid (Dosidicus gigas, d'Orbigny, 1835) pens and its moisture absorption ability (MAA) and deacetylating reaction were investigated and compared with α-chitin from shrimp shells. β-chitin was converted into α-form after 3 h in 40% NaOH or 1-3 h in 40% HCl solution,...

Physicochemical Properties of Frozen Fish Muscle as Affected by Trimethylamine-N-oxide demethylase (TMAOase)

Creator:: Lee, Jinhwan
Abstract:: Gadoid fish, like Alaska pollock and Pacific whiting, have a high level of trimethylamine-N-oxide demethylase (TMAOase) that catalyzes the breakdown of trimethylamine-N-oxide (TMAO) to formaldehyde (FA) and dimethylamine (DMA) even during frozen storage. FA reacts with amino acid residues to promote covalent cross-links in the formation of inter- and intramolecular...

Cyclosporine Biosynthesis in Tolypocladium inflatum Benefits Fungal Adaptation to the Environment

Creator:: Yang, Xiuqing, Feng, Peng, Yin, Ying, Bushley, Kathryn, Spatafora, Joseph W., and Wang, Chengshu
Abstract:: The cycloundecapeptide cyclosporin A (CsA) was first isolated from the insect-pathogenic fungus Tolypocladium inflatum for its antifungal activity and later developed as an immunosuppressant drug. However, the full biosynthetic mechanism of CsA remains unknown and has puzzled researchers for decades. In this study, the biosynthetic gene cluster is suggested to...
