Is There A Link Between Aging And Microbiome Diversity In Exceptional Mammalian Longevity?, Graham M. Hughes, John Leech, Sébastien J. Puechmaille, Jose V. Lopez, Emma C. Teeling

Marine & Environmental Sciences Faculty Articles

A changing microbiome has been linked to biological aging in mice and humans, suggesting a possible role of gut flora in pathogenic aging phenotypes. Many bat species have exceptional longevity given their body size and some can live up to ten times longer than expected with little signs of aging. This study explores the anal microbiome of the exceptionally long-lived Myotis myotis bat, investigating bacterial composition in both adult and juvenile bats to determine if the microbiome changes with age in a wild, long-lived non-model organism, using non-lethal sampling. The anal microbiome was sequenced using metabarcoding in more than 50 …

Pretreatment And Anaerobic Co-Digestion Of Selected Phb And Pla Bioplastics, Nicholas John Norio Benn, Daniel Zitomer

Civil and Environmental Engineering Faculty Research and Publications

Conventional petroleum-derived plastics are recalcitrant to biodegradation and can be problematic as they accumulate in the environment. In contrast, it may be possible to add novel, biodegradable bioplastics to anaerobic digesters at municipal water resource recovery facilities along with primary sludge to produce more biomethane. In this study, thermal and chemical bioplastic pretreatments were first investigated to increase the rate and extent of anaerobic digestion. Subsequently, replicate, bench-scale anaerobic co-digesters fed synthetic primary sludge with and without PHB bioplastic were maintained for over 170 days. Two polyhydroxybutyrate (PHB), one poly(3-hydroxybutyrate-co-4-hydroxybutyrate) and one polylactic acid (PLA) bioplastic were investigated. Biochemical methane …

Comparison Of Eosin And Fluorescein Conjugates For The Photoinitiation Of Cell-Compatible Polymer Coatings, Jacob L. Lilly, Anuhya Gottipati, Calvin F. Cahall, Mohamed Agoub, Brad J. Berron

Chemical and Materials Engineering Faculty Publications

Targeted photopolymerization is the basis for multiple diagnostic and cell encapsulation technologies. While eosin is used in conjunction with tertiary amines as a water-soluble photoinitiation system, eosin is not widely sold as a conjugate with antibodies and other targeting biomolecules. Here we evaluate the utility of fluorescein-labeled bioconjugates to photopolymerize targeted coatings on live cells. We show that although fluorescein conjugates absorb approximately 50% less light energy than eosin in matched photopolymerization experiments using a 530 nm LED lamp, appreciable polymer thicknesses can still be formed in cell compatible environments with fluorescein photosensitization. At low photoinitiator density, eosin allows more …

Nanostructured Multi-Functional Hybrid Nanocoatings From One-Step Coassembly, Jingjing Liu

Doctoral Dissertations

In this dissertation, a novel approach to fabricate organic/inorganic nanocoatings via a large-scale one-step coassembly process has been developed. The fabricated nanocoatings contain a high concentration of nanosheets (up to 70 wt. %) that can be well aligned along the substrate surface. A series of nanocoatings based on polyvinyl alcohol (PVA) together with various nanosheets including montmorillonite (MMT), laponite (LP), α-zirconium phosphate (ZrP), and graphene oxide (GO) were successfully fabricated using this one-step coassembly process. Different from other methods, this approach offers a high-speed one-step coassembly, in which hundreds of nanosheets can be aligned along the flow direction to form …

Specific Nanoporous Geometries On Anodized Alumina Surfaces Influence Astrocyte Adhesion And Glial Fibrillary Acidic Protein Immunoreactivity Levels, D. Ganguly, C. D.L. Johnson, M. K. Gottipati, D. Rende, D. A. Borca-Tasciuc, R. J. Gilbert

Chemical and Biochemical Engineering Faculty Research & Creative Works

Electrodes implanted in the brain or spinal cord trigger the activation of resident astrocytes. In their reactive state, astrocytes surrounding the electrode form a glial scar, compromising the ability of the electrode to interface with the surrounding neural tissue. One approach to reduce the inhibiting scar tissue is to incorporate nanoarchitecture on the surface of the implanted materials to modify the astrocytic response. The incorporated nanoarchitecture changes both the surface characteristics and the material properties of the implant interface. We investigated the response of rat cortical astrocytes to nanoporous anodic aluminum oxide (AAO) surfaces. Astrocytes were seeded onto nonporous aluminum …

“Foamation” Of A New Island Identity: An Analysis Of Foam In Derek Walcott’S Omeros, Joelle Milholm

Anthurium: A Caribbean Studies Journal

So much of postcolonial literature is about creating and revealing identities of places that were once conquered and branded to mimic their conquerors. This essay takes a unique look at just such a quest in Derek Walcott’s Omeros, as it explores the connection between Greek mythology and forming a postcolonial identity in St. Lucia. In this essay, I argue that Walcott blends native culture and classic myth, focused around the abundant use of the word “foam,” which appears forty-two times in the text. Foam’s etiology in Greek mythology is explained as the semen flowing from the castrated genitals of …

Long-Term Exposure Of Fine Particulate Matter Causes Hypertension By Impaired Renal D1 Receptor-Mediated Sodium Excretion Via Upregulation Of G-Protein-Coupled Receptor Kinase Type 4 Expression In Sprague-Dawley Rats., Xi Lu, Zhengmeng Ye, Shuo Zheng, Hongmei Ren, Jing Zeng, Xinquan Wang, Pedro A Jose, Ken Chen, Chunyu Zeng

Medicine Faculty Publications

BACKGROUND: Epidemiological evidence supports an important association between air pollution exposure and hypertension. However, the mechanisms are not clear.

METHODS AND RESULTS: Our present study found that long-term exposure to fine particulate matter (PM2.5) causes hypertension and impairs renal sodium excretion, which might be ascribed to lower D1 receptor expression and higher D1 receptor phosphorylation, accompanied with a higher G-protein-coupled receptor kinase type 4 (GRK4) expression. The in vivo results were confirmed in in vitro studies (ie, PM2.5 increased basal and decreased D1 receptor mediated inhibitory effect on Na+-K+ ATPase activity, decreased D1 receptor expression, and increased D1 receptor phosphorylation …

The Evolution Of Challenges For Adoptive Families: The Impact Of Age As A Framework For Differentiation, Nancy Rolock, Joan M. Blakey, Megan Wahl, Amy Devine

Journal of Adolescent and Family Health

This exploratory study examined issues parents (n=20) experienced after adoption through the child welfare system. The findings suggest that the primary differences between struggling and non-struggling families was whether the family was internally-protected or externally-focused. Internally-protected families were able to insulate and protect their family from many outside forces and meet their children’s needs. In contrast, externally-influenced families tended to have negative involvement with the school, community, and/or law enforcement, often resulting from children’s disruptive behavior. The parents had limited choices as to whether outside entities were involved in their children’s lives. Participants reported that sustained support after adoption is …

Influence Of The Bacterial Pigment Violacein On The Activity Of Some Protein Kinases, A.B. Soliev, A.T. Adylova, K. Hosokawa, K. Enomoto

Acta of Turin Polytechnic University in Tashkent

Experiments have been carried out to study the effect of violasein on the activity of various protein kinases. It was shown that violacein inhibits the protein kinase C (PKC) subfamily of the classical type, as well as some novel and atypical forms of PKC enzymes. Data on the inhibition of the activity of the catalytic subunits of protein kinase A and protein kinase C by violasein activity testify to the direct interaction of violacein with these sites of the complex enzyme molecule. Kinetic analysis of inhibition of PKA by violacein showed that inhibition occurs in a mixed type with respect …

A Fusion Detection Algorithm Targeted To Gene Expression Outliers Using Rna-Seq Data, Shahbozbek Abdunabiyev

Acta of Turin Polytechnic University in Tashkent

Nowadays there exist many bioinformatics tools that analyse sequencing data to identify genetic aberrations. The genetic aberrations can be amplification, mutation, copy number variation, fusion and so on. And they may cause pathology such as cancer. The identification of driving mechanism of pathology may lead us towards personalized or precise medicine. Personalized medicine is a medical model that uses genetic information of person’s disease to diagnose or treat the disease. The fusion detection tools are a subset of the bioinformatics tools that are targeted to find gene fusions. Usually, they have long execution time and work on the whole dataset …

Effects Of Ambient Particulate Matter On Aerobic Exercise Performance, Dale R. Wagner, Nicholas W. Clark

Kinesiology and Health Science Faculty Publications

Background/Objective: Wintertime thermal inversions in narrow mountain valleys create a ceiling effect, increasing concentration of small particulate matter (PM_2.5). Despite potential health risks, many people continue to exercise outdoors in thermal inversions. This study measured the effects of ambient PM_2.5 exposure associated with a typical thermal inversion on exercise performance, pulmonary function, and biological markers of inflammation.

Methods: Healthy, active adults (5 males, 11 females) performed two cycle ergometer time trials outdoors in a counterbalanced design: 1) low ambient PM_2.5 concentrations (/m³ ), and 2) an air quality index (AQI) ranking of “yellow.” Variables …

Coastal Upwelling Seasonality And Variability Of Temperature And Chlorophyll In A Small Coastal Embayment, Ryan K. Walter, Kevin Armenta, Brandon Shearer, Ian C. Robbins, John Steinbeck

Physics

While the seasonality of wind-driven coastal upwelling in eastern boundary upwelling systems has long been established, many studies describe two distinct seasons (upwelling and non-upwelling), a generalized framework that does not capture details relevant to marine ecosystems. In this contribution, we present a more detailed description of the annual cycle and upwelling seasonality for an understudied location along the central California coast. Using both the mean monthly upwelling favorable wind stress and the monthly standard deviation, we define the following seasons (contiguous months) and a transitional period (non-contiguous months): “Winter Storms” season (Dec-Jan-Feb), “Upwelling Transition” period (Mar and Jun), …

An Evaluation Of The Groundwater Microbial Community's Toluene Biogenesis Potential At A Site In Southeast Louisiana, Michael A. Griffin Jr.

LSU Master's Theses

The broad goal of the research described in this thesis was to better understand the potential for biological toluene production to occur in groundwater at a Superfund Site located in southeast Louisiana. Previous literature reported that bacterial isolates under laboratory test conditions and undefined microbial communities in anaerobic sludge digesters and seasonally stratified lakes can produce toluene biogenically. Most of the research reported on this subject previously, however, has been on systems in Europe and little research has been reported previously on such phenomena in North America.

In the research described here, studies were conducted utilizing groundwater from a Superfund …

Rate Of Performance Change In American Female Weightlifters Over Ten Years Of Competition, Jason Miller, Heidi Ventresca, Lindsay Bracken

International Journal of Exercise Science

International Journal of Exercise Science 11(6): 290-307, 2018. The purpose of this study was to evaluate the rates of performance change for American female weightlifters over 10 years of competition. Athlete performance results were gathered from the United States Weightlifting open access, results archive, database. Data was delimited to athletes (N ≥ 750) that competed in Youth or Junior Nationals to ensure athletes were <21yrs old at the first recorded competition. Competition results were converted to strength to mass (SM) ratios to control for the effect of bodyweight on performance. Starting with the first competition date, the highest SM for the snatch (SNT), clean and jerk (CJ) and combined total (T), in three month segments for three years, and six month segments over 10 years, were recorded. Observed percentage change in SM and Cohen’s d effect size (ES) between each 3- and 6-month segment and the first competition (baseline), for the SNT, CJ and T, was determined. Positive change in rate of …

Intersex And The Pardoner’S Body, Kim Zarins

Accessus

Most scholars today have retreated from reading into the Pardoner's body in favor of more figurative readings that emphasize his lack of masculinity, and such lack is then linked to his dejection and despair. Other, more affirming readings center the Pardoner's performance, which allows him to model any sort of body desired through figuration. While such positions dominate and older theories like Beryl Rowland's proposal of an intersex Pardoner are dismissed, in fact, an intersex reading might be a more life-affirming interpretation, not only in terms of reframing the Pardoner's body as manifesting variation as opposed to lack, but also …
