Investigating The Involvement Of The Tick Vector In The Induction Of Alpha-Galactose Hypersensitivity (Alpha-Gal Syndrome, Red Meat Allergy) In The United States., Gary Crispell
Dissertations
Alpha-gal syndrome (AGS or sometimes called red meat allergy) is a result of the development of specific IgE antibodies to the oligosaccharide galactose-α-1,3-galactose (α-gal) after a person has had exposure to tick bites. This dissertation investigates four common tick species found in North America: the lone-star tick (Amblyomma americanum), the Gulf-Coast tick (Amblyomma maculatum), the American dog tick (Dermacentor variabilis), and the black-legged tick (Ixodes scapularis) for the presence of α-gal by utilizing a combination of immunoproteomic approaches and carbohydrate analysis techniques.
Anti-α-gal IgM antibodies (M86) were used in immunoblotting to detect …
Ferrocenium Salt Aided Substitution Reactions And Synthesis Of Glycosylated Curcumin Derivatives, Deva Saroja Talasila
Ferrocenium Salt Aided Substitution Reactions And Synthesis Of Glycosylated Curcumin Derivatives, Deva Saroja Talasila
Dissertations
Organic synthesis has been significantly advanced with the employment of transition metal complexes. The discovery of transition metal catalysts provided the synthetic community with powerful tools for accelerating reactions and making them more selective and efficient. Many chemical reactions do not happen without a catalyst.
Iron-based catalysts have several advantages for the chemical industry because it is a non-toxic and ecologically friendly metal. Our group previously found that ferrocenium cations with a 3+ oxidation state of iron-catalyzed propargylic substitution reactions at low temperatures. The sandwich structure of ferrocenes allows substituents to be introduced on the cyclopentadienyl rings, which allows for …
Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky
Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky
Open Educational Resources
The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.
Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …
The Kinetic Characterization Of Two Putative Galactosidases, Bt2857 And Sco6594, And The Preliminary Analyses Of Sco6595-97, Maria Ngo
Theses and Dissertations (Comprehensive)
Bacteroides thetaiotaomicron is a prolific bacterium found in the distal intestinal tract of humans that possesses the ability to breakdown complex polysaccharides through the release of carbohydrate-active enzymes (CAZymes). Overall, the saccharolytic prowess of B. thetaiotaomicron presents an intriguing model for understanding microbial-host nutrient exchange within the gut and to identify novel mechanisms for accessing carbohydrates. The successful expression, purification, and preliminary kinetic characterization of BT2857 are reported. BT2857 was found to be enzymatically active against the artificial substrate, 4-nitrophenyl β-D-galactopyranoside (pNP-Gal); suggesting its role as a putative β-galactosidase and allowed for the quantification of BT2857 activity by the determination …

The essential role of the lipophosphoglycan (LPG) of Leishmania in innate immune response has been extensively reported. However, information about the role of the LPG-related glycoinositolphospholipids (GIPLs) is limited, especially with respect to the New World species of Leishmania. GIPLs are low molecular weight molecules covering the parasite surface and are similar to LPG in sharing a common lipid backbone and a glycan motif containing up to 7 sugars. Critical aspects of their structure and functions are still obscure in the interaction with the vertebrate host. In this study, we evaluated the role of those molecules in two medically important …

Lafora Disease (LD) is a fatal neurodegenerative epileptic disorder that presents as a neurological deterioration with the accumulation of insoluble, intracellular, hyperphosphorylated carbohydrates called Lafora bodies (LBs). LD is caused by mutations in either the gene encoding laforin or malin. Laforin contains a dual specificity phosphatase domain and a carbohydrate-binding module, and is a member of the recently described family of glucan phosphatases. In the current study, we investigated the functional and physiological relevance of laforin dimerization. We purified recombinant human laforin and subjected the monomer and dimer fractions to denaturing gel electrophoresis, mass spectrometry, phosphatase assays, protein-protein interaction assays, …
