Using An Old Assay In New Ways: Differential Scanning Calorimetry Characterization, Quantification, And Interaction Analysis Of Whey Proteins, Charity Conlin Jennings

Theses and Dissertations

Whey proteins including β-Lactoglobulin, α-Lactalbumin, Immunoglobulin-G, Serum Albumin, Lactoferrin, and Lactoperoxidase each have unique biological properties spanning anti-bacterial, anti-fungal, and anti-viral activities as well as deliver essential nutrients to the human body. In the past decade, there has been a large focus on extracting these individual proteins for their use in foods and supplements. In order to best extract these proteins and prepare them properly in foods and supplements, an understanding of how they behave and denature in different environments is necessary. However, there is insufficient knowledge of their thermodynamic properties and potential interactions in varying conditions. Additionally, there are …

Sequestration Of Plant Defenses By Spotted Lanternfly (Lycorma Delicatula) And Effects On Avian Predators, Anne E. Johnson, Allison Cornell, Fang Zhu, Ashley E. Shay, Gabrielle Davis, Kelli Hoover

Biology Faculty Publications

Lycorma delicatula is a polyphagous phloem feeder, which is spreading rapidly in the U.S., and is a major threat to grapes, hops, and ornamentals. Among its hosts, L. delicatulaprefers Ailanthus altissima, an invasive tree from which it sequesters toxins, including several quassinoid compounds. We tested how these defenses affected predation by birds of nymphal and adult L. delicatula. Freeze-killed nymphs of each instar were reared with or without access to A. altissima and placed into cups on top of nest boxes occupied by house wrens (Troglodytes aedon). House wrens ate or fed their chicks a …

Objective

Smoking has been associated with psychiatric and somatic comorbidities in bipolar disorder (BD) populations. However, studies in older age BD (OABD) populations are sparse. We hypothesized that among individuals with OABD, current and former smokers would have worse psychiatric and somatic comorbidities parameters compared to never smokers.

Method

Our study used baseline cross-sectional data from 27 international studies reporting data on adults 50 years old and older (N = 984). Smoking status was categorized into current smokers, former smokers, and never smokers. The distribution of demographic and clinical variables was assessed. The associations between smoking status and the …

Cdk4/6 Inhibitors In Breast Cancer-Who Should Receive Them?, Anran Chen, Ze-Yi Zheng, Meenakshi Anurag, Ahmed Elkhanany, Natalie C Chen, Eric C Chang

Faculty, Staff and Students Publications

More than 70% of breast cancers are estrogen receptor-positive (ER+). Endocrine therapy that blocks estrogen signaling remains the cornerstone of treatment, yet relapses continue to affect many patients. Cyclin-dependent kinases 4 and 6 (CDK4/6) regulate the G1-S phase transition in the cell cycle, and pharmacological inhibition of this pathway has been successfully leveraged to reduce recurrence. CDK4/6 inhibitors combined with endocrine therapy are now the standard of care, although determining the optimal patient population for treatment remains a key challenge. A newly published study provides important insight, showing that loss of the NF1/neurofibromin tumor suppressor confers greater sensitivity to CDK4/6 …

Department of Microbiology and Immunology Faculty Papers

Onchocerciasis remains a significant cause of morbidity and economic loss in sub-Saharan Africa. Despite the existence of effective therapeutics, a prophylactic vaccine targeting the etiologic agent, Onchocerca volvulus, is needed to control ongoing disease and transmission. Mice were vaccinated against O. volvulus with a fusion of the recombinant antigens Ov-103 and Ov-RAL-2 (Ov-FUS-1) with Advax-CpG adjuvant. Immunized mice developed protective immunity with the killing of third-stage larvae (L3) within 36 h of challenge infection. IgG from immunized mice passively transferred protective immunity to naïve mice, indicating that antigen-specific IgG mediated parasite elimination. Neutrophils were the most abundant subset of immune …

The intestinal mucosal epithelium forms a barrier between luminal contents and the body. MicroRNAs (miRNAs) regulate mucosal homeostasis by controlling inflammatory responses and structural integrity. Here, we discovered a protective role for miR147 in intestinal inflammation using a miR147tdTomato reporter mouse. miR147 was enriched in the intestines, with the highest expression in the colonic epithelial cells at the luminal surface, with prominent expression in differentiated enterocytes. Mice with general or intestinal epithelial deletion of miR147 showed increased intestinal inflammation and diminished mucosal healing during colitis. RNA sequencing of miR147-deficient cells showed dysregulated immune signaling, with upregulated proinflammatory cytokine pathways and …

Evaluation Of Host Resistance To Rotylenchulus Reniformis In Sweetpotato Germplasm, Timothy S. Miller

LSU Master's Theses

The reniform nematode (Rotylenchulus reniformis) is an emerging plant-parasitic threat to sweetpotato production. Dissimilar from the galling caused by root-knot nematode infections, infections from the reniform nematode occur without visible damage to the root system. In the southern United States, heavily infested sweetpotato fields can lose up to 40% of their total yield. Growers rely heavily on fumigants and nematicides which provide inconsistent control and are not sustainable in the long-term. Past research has been more focused on the efficacy of chemicals than in the identification of host resistance or tolerance in sweetpotato germplasm. This study evaluated past …

Dissolved Inorganic Carbon Metabolism In Bacteria, Jana Wieschollek

USF Tampa Graduate Theses and Dissertations

Dissolved inorganic carbon (DIC: CO2, HCO3⁻, CO32⁻) plays a central role in the metabolism of all living organisms. DIC is necessary for steps in essential biosynthetic processes, such as the synthesis of amino acids and nucleobases; in autotrophic bacteria, organic molecules are synthesized entirely from DIC. To ensure a steady supply of CO2 and HCO3 - needed for biosynthesis and/or autotrophy, organisms use bicarbonate transporters to increase the cytoplasmic concentration of this anion, and carbonic anhydrase (CA) to speed the interconversion of CO2 and HCO3 -, both in the cytoplasm and at the cell surface. This dissertation investigates DIC metabolism …
