Tick Saliva And The Alpha-Gal Syndrome: Finding A Needle In A Haystack, Surendra Raj Sharma, Shahid Karim Jul 2021

Tick Saliva And The Alpha-Gal Syndrome: Finding A Needle In A Haystack, Surendra Raj Sharma, Shahid Karim

Faculty Publications

Ticks and tick-borne diseases are significant public health concerns. Bioactive molecules in tick saliva facilitate prolonged blood-feeding and transmission of tick-borne pathogens to the vertebrate host. Alpha-gal syndrome (AGS), a newly reported food allergy, is believed to be induced by saliva proteins decorated with a sugar molecule, the oligosaccharide galactose-⍺-1,3-galactose (α-gal). This syndrome is characterized by an IgE antibody-directed hypersensitivity against α-gal. The α-gal antigen was discovered in the salivary glands and saliva of various tick species including, the Lone Star tick (Amblyomma americanum). The underlying immune mechanisms linking tick bites with α-gal-specific IgE production are poorly understood and are …

Retinoids As Chemo-Preventive And Molecular-Targeted Anti-Cancer Therapies., Victoria O. Hunsu, Caroline O.B. Facey, Jeremy Z. Fields, Bruce M. Boman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Retinoic acid (RA) agents possess anti‐tumor activity through their ability to induce cellular differentiation. However, retinoids have not yet been translated into effective systemic treatments for most solid tumors. RA signaling is mediated by the following two nuclear retinoic receptor subtypes: the retinoic acid receptor (RAR) and the retinoic X receptor (RXR), and their isoforms. The identification of mutations in retinoid receptors and other RA signaling pathway genes in human cancers offers opportunities for target discovery, drug design, and personalized medicine for distinct molecular retinoid subtypes. For example, chromosomal translocation involving RARA occurs in acute promyelocytic leukemia (APL), and all‐trans …

Chemistry Faculty Research & Creative Works

Acinetobacter baumannii is an opportunistic pathogen with a high mortality rate due to multi-drug-resistant strains. The synthesis and uptake of the iron-chelating siderophores acinetobactin (Acb) and preacinetobactin (pre-Acb) have been shown to be essential for virulence. Here, we report the kinetic and structural characterization of BauF, a flavin-dependent siderophore-interacting protein (SIP) required for the reduction of Fe (III) bound to Acb/pre-Acb and release of Fe(II). Stopped-flow spectrophotometric studies of the reductive half-reaction show that BauF forms a stable neutral flavin semiquinone intermediate. Reduction with NAD(P)H is very slow (kobs, 0.001 s-1) and commensurate with the rate of reduction by photobleaching, …

Chitin, a major component of fungal cell walls, has been associated with allergic disorders such as asthma. However, it is unclear how mammals recognize chitin and the principal receptor(s) on epithelial cells that sense chitin remain to be determined. In this study, we show that LYSMD3 is expressed on the surface of human airway epithelial cells and demonstrate that LYSMD3 is able to bind chitin, as well as β-glucan, on the cell walls of fungi. Knockdown or knockout of LYSMD3 also sharply blunts the production of inflammatory cytokines by epithelial cells in response to chitin and fungal spores. Competitive inhibition …


Effects Of Wetland Management And Associated Abiotic Factors On Rare Plant Communities Of Spring-Fed Arid Wetlands, Antonio Cantu De Leija Jul 2021

Effects Of Wetland Management And Associated Abiotic Factors On Rare Plant Communities Of Spring-Fed Arid Wetlands, Antonio Cantu De Leija

LSU Master's Theses

Spring-fed arid wetlands support high biological productivity and are hotspots for endemism and distribution of rare plants, making them areas of high conservation value. These systems are driven by complex interactions among groundwater discharge and the geomorphic and climatic features of the setting, which provide gradients of edaphic conditions, particularly soil moisture and salinity that influence the presence and abundance of rare plant communities. However, spring-fed arid wetlands are at particular risk of increases in salinity and drier hydrological regimes due to anthropogenic activities. Such alterations to abiotic conditions may jeopardize the distribution and abundance of rare plants by exceeding …


Optimization Of Mechanical Properties At The Infarct Border Zone, Kaushik Sunder Jul 2021

Optimization Of Mechanical Properties At The Infarct Border Zone, Kaushik Sunder

LSU Master's Theses

A myocardial infarction (MI) occurs every 39 seconds in the United States. As of 2016, an estimated 550,000 new and 200,000 recurrent episodes of myocardial infarction (MI) occur each year in the United States was. Infarction is often distinguished by a considerable decrease in wall thickness and an increase in heart size or left ventricular volume. This behavior happens when there is a prolonged lack of blood flow, usually due to damage or clotting, which causes cardiomyocytes to die (CMs). The development of non-contractile infarct scarring is the primary pathophysiology of MI. While the infarct scar prevents myocardial rupture during …

“Unspoken Understanding”: The Evolution Of Chinese American Adoption Communities, Annie Abruzzo Jul 2021

“Unspoken Understanding”: The Evolution Of Chinese American Adoption Communities, Annie Abruzzo

Swarthmore Undergraduate History Journal

While scholarly work on adoption, transnational adoption, and specifically international adoption from China has been robust, it has tended to focus on studying parents and parenting. This paper analyzes the resources used by both parents and children to discuss race, culture, and adoption, and seeks to understand the effects of these parenting strategies on Chinese American adoptees, who have begun to reach young adulthood in the last ten years. Examination of the recent growth of adoptee communities reveals that a shared and complex adoptee identity is a more powerful nexus than shared Chineseness.

Unusual subjects:

Finding model communities among marginalized populations

This paper is inspired by the questions that we have asked ourselves since we first met at Schenectady County Community College. What is it, we wondered, that keeps so many of our fellow Americans seemingly wedded to a political economy that is sustainable only at great cost? Could we use our academic work to help spread awareness about people who dared to demand different lives? And might our studies suggest strategies to work for change?

We currently all pursue different projects, but we share a belief that one obstacle to progressive change …
