Here’S The Tea: Antioxidant Capacity And Phenolic Content Of Various Commercial Teas, Shay Lynn Greco Nov 2022

Here’S The Tea: Antioxidant Capacity And Phenolic Content Of Various Commercial Teas, Shay Lynn Greco

Biochemistry and Molecular Biology

Tea is historically a widely consumed beverage globally, second only to water. Tea beverages are known to provide plentiful health benefits related to aging and general well-being. Drinking teas may also reduce the risk of many diseases such as developing cancers and vascular diseases. These ancient beverages have a variety of biological activities including anti-tumor, antioxidant and anti-obesity properties. The chemical mechanisms for these health benefits are related to the phenolic and flavonoid compounds present in teas. In this study, the infusions of commercial teas were analyzed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3- ethylbenzothiazoline-6-sulfonic acid (ABTS) assays to determine the …

Three experiments evaluated the effects of three corn silage hybrids, inclusion, and nutrient digestibility in growing and finishing diets. The three hybrids tested included a control (CON), a hybrid containing a brown midrib (bm3) trait (BM3), and an experimental bm3 hybrid with the soft endosperm trait (BM3-SOFT). Experiment 1 utilized 360 crossbred steers (body weight [BW] = 334; SD = 25 kg) to evaluate inclusion of silage in a finishing diet at (15% or 45% of diet dry matter [DM]) and silage hybrid (CON, BM3, or BM3-SOFT). Experiment 2 and 3 utilized 216 crossbred steers (BW = 324; SD = …


Productivity To Precarity On Instagram: Digital Feminism In India During The Covid-19 Pandemic, Anhiti Patnaik Nov 2022

Productivity To Precarity On Instagram: Digital Feminism In India During The Covid-19 Pandemic, Anhiti Patnaik

Wagadu: A Journal of Transnational Women's & Gender Studies

This paper examines how digital feminism deconstructed neoliberal ideals of technological productivity in India during the Covid-19 pandemic. By creating a productivity scale, I delineate new social disparities and risk factors brought on by the unprecedented shift to a work-from-home digital economy. Through theories of biopower, I argue that technology is not neutral, apolitical, or unequivocally in favour of equal access and human rights. The creation of a new social group termed the 'technoprecariat' during lockdown is discussed using a 'cripqueer' approach to digital feminism. I extend Judith Butler's early work on gender performativity to the neo-liberal ideal of gender …

Ecology, Evolution, and Behavior

A 12-week exposure study was conducted to evaluate the growth performance and activities of some liver enzymes of African catfish (Clarias gariepinus) juveniles cultured in water hyacinth (Eichhornia crassipes) infested concrete and plastic culture media. 152 fish juveniles were introduced into two large concrete tanks (6.0 m × 5.0 m × 1.2 m) for the outdoor experiment. A tank was infested with E. crassipes plant at a density of 12.30 plants/m2, while the other tank, which served as the control, contained no water hyacinth plant. For the laboratory experiment, 50 fish juveniles were stocked in duplicate into five …


Gruel And Unusual: Prison Punishment Diets And The Eighth Amendment, Jackie Cuellar Nov 2022

Gruel And Unusual: Prison Punishment Diets And The Eighth Amendment, Jackie Cuellar

Minnesota Law Review Vols. 106:2 onward (2021-present)

For as long as prisons have existed, food has been used as a mechanism of prisoner control. One of the earliest forms of food as punishment was the aptly named “bread-and-water diet,” providing prisoners with just 700 calories per day. The diet was later deemed cruel and unusual in violation of the Eighth Amendment, but this was far from the last use of food as punishment in prisons. Today, one disciplinary diet persists in correctional facilities across the country—nutraloaf. The exact recipe for nutraloaf varies but typically involves blending together bread, potatoes, non-dairy cheese, beans, fruits, and vegetables, shaping it …


Women's Agency And Pastoral Livelihoods In India: A Review, Aayushi Malhotra, Sailaja Nandigama, Kumar Sankar Bhattacharya Nov 2022

Women's Agency And Pastoral Livelihoods In India: A Review, Aayushi Malhotra, Sailaja Nandigama, Kumar Sankar Bhattacharya

Wagadu: A Journal of Transnational Women's & Gender Studies

The role of women in promoting and sustaining pastoral livelihoods remains an under-researched area across the world. Often, studies discuss pastoralism as a male-oriented enterprise, thus overshadowing or ignoring the part played by women in such livelihood practices. In India, where pastoralism itself is essentially a neglected area of research, such discussions remain even sparse. Pastoral communities depending on migratory livestock rearing practices for their livelihoods exhibit gender-based differences in their everyday life in terms of division of labour, mobility patterns, and rights over resources. Women play different roles and responsibilities at the household and community levels that remain intertwined …

Phytochemical Targeting Of Mitochondria For Breast Cancer Chemoprevention, Therapy, And Sensitization, Elizabeth R.M. Zunica, Christopher L. Axelrod, John P. Kirwan

Division of Basic Science Faculty Publications

Breast cancer is a common and deadly disease that causes tremendous physical, emotional, and financial burden on patients and society. Early-stage breast cancer and less aggressive subtypes have promising prognosis for patients, but in aggressive subtypes, and as cancers progress, treatment options and responses diminish, dramatically decreasing survival. Plants are nutritionally rich and biologically diverse organisms containing thousands of metabolites, some of which have chemopreventive, therapeutic, and sensitizing properties, providing a rich source for drug discovery. In this study we review the current landscape of breast cancer with a central focus on the potential role of phytochemicals for treatment, management, …

Comparison Review Of The Production, Microbiology, And Sensory Profile Of Lambic And American Coolship Ales, John Carriglio, Drew Budner, Katherine A. Thompson-Witrick Nov 2022

Comparison Review Of The Production, Microbiology, And Sensory Profile Of Lambic And American Coolship Ales, John Carriglio, Drew Budner, Katherine A. Thompson-Witrick

Chemistry

Sour beers have been traditionally brewed with spontaneous fermentation. This has been occurring in Belgium for hundreds of years, and more recently in the United States as the American craft beer industry has boomed. Belgian sour styles include lambics, which are mirrored in a burgeoning style called the American coolship ale (ACA). American beers have much more creative leeway than their Belgian counterparts, as American craft brewing tends to incorporate more contemporary techniques and ingredients than their traditional European forebears. This review paper will summarize the history, production methods, fermentation, microbiological profiles, and sensory profiles of Belgian lambics and American …

A community garden is a great way of expanding the library's service beyond its four walls and promoting patron collaboration. The library garden was imagined with the purpose of teaching, demonstrating, donating and involving families in growing food and experiencing the immense satisfaction derived from harvesting home-grown produce. Library gardens are a natural setting for promoting nutritional literacy and hands-on environmental learning. The North Cobb Regional Library Garden reflects Cobb County Public Library's mission of being a vital resource center providing services to enrich people's lives.


Development Of A Targeted Mass Spectrometry Method For The Detection And Quantification Of Peanut Protein In Incurred Food Matrices, Sara Schlange Nov 2022

Development Of A Targeted Mass Spectrometry Method For The Detection And Quantification Of Peanut Protein In Incurred Food Matrices, Sara Schlange

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The unintentional presence of peanut in food products through allergen cross-contact is a considerable safety concern for peanut-allergic individuals. The food industry monitors for this contamination using immunoassays; however, these detection methods demonstrate issues with recovery and accurate quantification of allergenic protein when analyzing processed, complex food matrices. Of particular concern is the deficit in immunoassay-based detection and quantification of peanut in cookie and dark chocolate matrices, as the unintentional presence of peanut has been observed in these food products. A liquid chromatography with tandem mass spectrometry (LC-MS/MS) method for the detection and quantification of peanut protein in cookie and …

Safety Assessment Of Novel Foods And Food Proteins, Niloofar Moghadam Maragheh

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The global food market needs to grow and supply food demand to feed the growing world population. Alternative food proteins, including novel sources of safe foods and ingredients, are the candidates that could provide more environmentally sustainable choices, animal welfare, and consumers health. Novel foods and food proteins must undergo premarket safety evaluations including allergenicity assessment to reduce the risk of cross-reactivity with known allergens and uncharacterized risk to food allergic individuals. This research addressed the safety assessment of some novel foods and food ingredients using the study of stability of proteins in pepsin and sequence identity analysis in the …


Identification Of Gut Microbiome Composition Responsible For Gas Production, Erasme Mutuyemungu Nov 2022

Identification Of Gut Microbiome Composition Responsible For Gas Production, Erasme Mutuyemungu

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Gas production remains a significant barrier to increasing intake of dietary fiber-containing foods for many consumers. Therefore, this thesis is comprised of two studies focusing on the role of the gut microbiome in contributing to gas production during fermentation of dietary components. Previous studies have reported significant correlations between Megasphaera elsdenii and gas production during fermentation of pulses. Therefore, the objective of the first study was to determine the role of M. elsdenii in gas production by the microbiome during fermentation of foods commonly associated with gas production. Human fecal microbiomes were separated based on the presence (Me+) or absence …


Evaluation Of Wheat-Specific Peptide Targets For Use In The Development Of Elisa And Mass Spectrometry-Based Detection Methods, Jessica Humphrey Nov 2022

Evaluation Of Wheat-Specific Peptide Targets For Use In The Development Of Elisa And Mass Spectrometry-Based Detection Methods, Jessica Humphrey

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Individuals with IgE-mediated wheat allergy and celiac disease must avoid the consumption of wheat. Those with celiac disease must also avoid rye and barley in addition to wheat as these make up the gluten-containing grains. To ensure products are accurately labeled, ELISA methods may be used to monitor compliance with food allergen and gluten-free regulations. Currently, available ELISA methods for wheat detection utilize monoclonal antibodies that target peptides from the gluten fraction of proteins, and therefore, also detect rye and barley. Limitations such as differing antibody reactivity and unequal gluten content among wheat, rye, and barley have led to inconsistent …


Occurrence Of Hydroxyproline In Proteomes Of Higher Plants, Olivia Huffman Nov 2022

Occurrence Of Hydroxyproline In Proteomes Of Higher Plants, Olivia Huffman

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Food allergies affect millions of individuals across the United States and worldwide. Peanut allergies are among the most severe food allergies because of their potentially life-threatening symptoms and lifelong persistence. Potent peanut allergen, Ara h 2, is known to contain an amino acid motif containing the posttranslational modification, hydroxyproline (HyP). HyP is associated with immunogenic response when present both in Ara h 2 and in timothy grass pollen allergen, Phl p 1. To further explore the presence of HyP in higher plants and specifically to investigate its potential presence in commonly allergenic plants, a study of 26 plant seeds was …


The Formal Institutional Context Of Informal Entrepreneurship: A Cross-National, Configurational-Based Perspective, Joshua K. Ault, Andrew Spicer Nov 2022

The Formal Institutional Context Of Informal Entrepreneurship: A Cross-National, Configurational-Based Perspective, Joshua K. Ault, Andrew Spicer

Faculty Publications

While previous comparative research has identified the formal institutional conditions that differentiate countries on their degree of informal entrepreneurship, this paper examines the characteristics that shape cross-national diversity in its type. Based on a series of fuzzy-set qualitative comparative analyses (fs/QCA) of 138 country cases, we find evidence of causal heterogeneity in the configuration of institutional conditions associated with entrepreneurial outcomes that are informal and growth-oriented and those that are informal and subsistence-oriented. Given our results, we propose that the formal institutional-based conditions that differentiate between types of informal sectors are best identified by the conjoint mixture of strength and …


Trypanosome Infection Disturbs The Gut Microbiota Of Bumble Bee Hosts, Bryan Sierra-Rivera Nov 2022

Trypanosome Infection Disturbs The Gut Microbiota Of Bumble Bee Hosts, Bryan Sierra-Rivera

Theses and Dissertations

Host-microbe interactions are ubiquitous with both positive and negative outcomes for host health and fitness. While pathogens abound, there has been an increased focus beneficial host-microbial community associations, such as native gut microbiota that can aid in disease resistance, nutrient sequestration, and detoxification. However, while beneficial microbes can protect against infection, there is a limited appreciation for how pathogen infection may disrupt healthy gut microbiota structure and function. Crithidia bombi is a common trypanosomatid gut parasite of bumble bees with fitness-relevant effects on individuals and colonies. The native bumble bee gut microbiota has been shown to increase protection against Crithidia, …

Evolution Of Immune Function In Response To Dietary Macronutrients In Male And Female Decorated Crickets, Corinne Letendre, Alejandro Rios-Villamil, Alexandria Williams, James Rapkin, Scott K. Sakaluk, Clarissa M. House, John Hunt

Faculty Publications – Biological Sciences

Although dietary macronutrients are known to regulate insect immunity, few studies have examined their evolutionary effects. Here, we evaluate this relationship in the cricket Gryllodes sigillatus by maintaining replicate populations on four diets differing in protein (P) to carbohydrate (C) ratio (P‐ or C‐biased) and nutritional content (low‐ or high‐nutrition) for >37 generations. We split each population into two; one maintained on their evolution diet and the other switched to their ancestral diet. We also maintained populations exclusively on the ancestral diet (baseline). After three generations, we measured three immune parameters in males and females from each population. Immunity was …


Snapshots Of Coastal Ecology During Glacial And Deglacial Intervals: A Multiproxy Assessment Of Northern Gulf Of Mexico Sediment Cores, Kendall Emilie Brome Nov 2022

Snapshots Of Coastal Ecology During Glacial And Deglacial Intervals: A Multiproxy Assessment Of Northern Gulf Of Mexico Sediment Cores, Kendall Emilie Brome

LSU Master's Theses

Terrestrial ecosystems along exposed continental shelves during times of relatively low sea level and glaciation are rarely preserved due to the mechanically erosive nature of marine transgression and regression. In this study, I investigate the geochemical and palynological characteristics of two well-preserved sites in the northern Gulf of Mexico (NGOM) to determine the ecologic settings and subsequent mechanisms of preservation in this region. Both sites contain preserved terrigenous sediments of previously exposed coastal margins; the first is located at the Alabama Underwater Forest (~13 km south of Gulf Shores, AL, at ~15 mbsl), and optically stimulated luminescence dates to 72–56 …
