‘Coronated’ Consumption In The Viral Market, Soonkwan Hong

Markets, Globalization & Development Review

The universal exposure to the virus has disrupted institutions, redefined values, and reshaped systems, including the market. Idling, uncertainty, and liquidity encapsulate the ever-precarious individual lives and the reflexive socio-politico-cultural changes. These conditions and consequences nonetheless create paradoxical opportunities in the viral market. The new meaning of connectivity that promotes high-viscosity relationships and high-visibility identities will transform the market to better acknowledge and support humans and the new sociality.

Genomic Modeling As An Approach To Identify Surrogates For Use In Experimental Validation Of Sars-Cov-2 And Hunov Inactivation By Uv-C Treatment, Brahmaiah Pendyala, Ankit Patras, Bharat Pokharel, Doris D’Souza

Agricultural and Environmental Sciences Faculty Research

Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV-2) is responsible for the COVID-19 pandemic that continues to pose significant public health concerns. While research to deliver vaccines and antivirals are being pursued, various effective technologies to control its environmental spread are also being targeted. Ultraviolet light (UV-C) technologies are effective against a broad spectrum of microorganisms when used even on large surface areas. In this study, we developed a pyrimidine dinucleotide frequency based genomic model to predict the sensitivity of select enveloped and non-enveloped viruses to UV-C treatments in order to identify potential SARS-CoV-2 and human norovirus surrogates. The results revealed that …

Analyses Of The Expression, Immunohistochemical Properties And Serodiagnostic Potential Of Schistosoma Japonicum Peroxiredoxin-4, Minh-Anh Dang-Trinh, Jose Ma. M. Angeles, Kharleezelle J. Moendeg, Adrian Miki C. Macalanda, Thu-Thuy Nguyen, Luna Higuchi, Shotaro Nakagun, Masahi Kirinoki, Yuichi Chigusa, Yasuyuki Goto, Shin-Ichiro Kawazu

Biology Faculty Publications

Background

Schistosoma japonicum, which inhabits the mesenteric vein of the mammalian hosts for about 20 to 30 years, is subjected to the oxidative stresses from the host defense mechanism during their intra-mammalian stages. To counteract this host immune attack, the parasite utilizes their antioxidant system for survival inside the host. Peroxiredoxins (Prxs), thiol-specific antioxidant proteins, play an essential role for protecting the parasite against oxidative stress by reducing hydrogen peroxide to water. Only three types of 2-Cys Prxs have been previously characterized in S. japonicum whereas a fourth Prx has been identified for Schistosoma mansoni as Prx-4. A sequence …

Mesenchymal Stem Cells And Their Extracellular Vesicles: A Potential Game Changer For The Covid-19 Crisis, Dina H. Kassem, Mohamed M. Kamal

Pharmacy

Corona virus disease 2019 (COVID-19) is a global public health crisis. The high infectivity of the disease even from non-symptomatic infected patients, together with the lack of a definitive cure or preventive measures are all responsible for disease outbreak. The severity of COVID-19 seems to be mostly dependent on the patients’ own immune response. The over-activation of the immune system in an attempt to kill the virus, can cause a “cytokine storm” which in turn can induce acute respiratory distress syndrome (ARDS), as well as multi-organ damage, and ultimately may lead to death. Thus, harnessing the immunomodulatory properties of mesenchymal …

Neoantigen-Specific Cd4(+) T-Cell Response Is Critical For The Therapeutic Efficacy Of Cryo-Thermal Therapy, Peng Peng, Hong-Ming Hu, Ping Liu, Lisa X Xu

Articles, Abstracts, and Reports

Background: Traditional tumor thermal ablations, such as radiofrequency ablation (RFA) and cryoablation, can result in good local control of tumor, but traditional tumor thermal ablations are limited by poor long-term survival due to the failure of control of distal metastasis. Our previous studies developed a novel cryo-thermal therapy to treat the B16F10 melanoma mouse model. Long-term survival and T-cell-mediated durable antitumor immunity were achieved after cryo-thermal therapy, but whether tumor antigen-specific T-cells were augmented by cryo-thermal therapy was not determined.

Methods: The long-term antitumor therapeutic efficacy of cryo-thermal therapy was performed in B16F10 murine melanoma models. Splenocytes derived from mice …

Sodium Butyrate Reduces Salmonella Enteritidis Infection Of Chicken Enterocytes And Expression Of Inflammatory Host Genes In Vitro, Anamika Gupta, Mohit Bansal, Basanta Raj Wagle, Xiaolun Sun, Narayan Rath, Annie Donoghue, Abhinav Upadhyay

Poultry Science Faculty Publications and Presentations

Salmonella Enteritidis (SE) is a facultative intracellular pathogen that colonizes the chicken gut leading to contamination of carcasses during processing. A reduction in intestinal colonization by SE could result in reduced carcass contamination thereby reducing the risk of illnesses in humans. Short chain fatty acids such as butyrate are microbial metabolites produced in the gut that exert various beneficial effects. However, its effect on SE colonization is not well known. The present study investigated the effect of sub-inhibitory concentrations (SICs) of sodium butyrate on the adhesion and invasion of SE in primary chicken enterocytes and chicken macrophages. In addition, the …

Integrate Structural Analysis, Isoform Diversity, And Interferon-Inductive Propensity Of Ace2 To Predict Sars-Cov2 Susceptibility In Vertebrates, Eric R. Sang, Yun Tian, Yuanying Gong, Laura C. Miller, Yongming Sang

Agricultural and Environmental Sciences Faculty Research

The current new coronavirus disease (COVID-19) has caused globally over 0.4/6 million confirmed deaths/infected cases across more than 200 countries. As the etiological coronavirus (a.k.a. SARS-CoV2) may putatively have a bat origin, our understanding about its intermediate reservoir between bats and humans, especially its tropism in wild and domestic animals are mostly unknown. This constitutes major concerns in public health for the current pandemics and potential zoonosis. Previous reports using structural analysis of the viral spike protein (S) binding its cell receptor of angiotensin-converting enzyme 2 (ACE2), indicate a broad potential of SARS-CoV2 susceptibility in wild and particularly domestic animals. …

The Kinetics Of Influenza A (A/California/4/2009-H1n1) And B (B/Phuket/3073/2013 (Byam), B/Brisbane/60/2008 (Bvic)) Virus Infection In Ferrets, Demi L. Erickson

Honors Thesis

Influenza is a persistent threat to individual and global health. Seasonal influenza kills nearly 500,000 people globally each year. Influenza viruses have circulated within the human population, causing a significant disease burden. In order to create the most effective antiviral therapies, knowledge concerning all lineages of influenza must be studied accurately and thoroughly. The influenza virus itself is not always responsible for these mortalities, rather, the secondary bacterial infections associated with death. In order to protect the population and examine the secondary infections that arise, the kinetics of influenza must be studied entirely. To understand the kinetics, researchers are turning …

The Impact Of Myeloid-Mediated Co-Stimulation And Immunosuppression On The Anti-Tumor Efficacy Of Adoptive T Cell Therapy, Pasquale Patrick Innamarato

USF Tampa Graduate Theses and Dissertations

Adoptive T cell therapy (ACT) in combination with lymphodepleting chemotherapy is an effective strategy to induce the eradication of tumors, providing long-term regression in cancer patients. However, only a minority of patients that receive ACT with tumor infiltrating lymphocytes (TILs) exhibit durable benefit. Thus, there is an urgent need to define strategies that potentiate anti-tumor activity conducted by adoptively transferred T cells. In these studies, we aimed to identify novel strategies to enhance the therapeutic efficacy of ACT. Accordingly, we describe the disparate roles of myeloid cells in the context of ACT characterized by the augmentation of TIL proliferation in …

Increased Diversity And Novel Subtypes Among Clinical Cryptosporidium Parvum And Cryptosporidium Hominis Isolates In Southern Ireland, Jennifer K. O'Leary, Liam Blake, Gerard D. Corcoran, Roy D. Sleator, Brigid Lucey

Department of Biological Sciences Publications

Reported incidence rates of cryptosporidiosis in Ireland are consistently among the highest in Europe. Despite the national prevalence of this enteric parasite and the compulsory nature of incidence surveillance and reporting, in-depth analyses seeking to genotype clinical isolates of Cryptosporidium on an intra-species level are rarely undertaken in Ireland. This molecular epidemiology study of 163 clinical Cryptosporidium isolates was conducted in Southern Ireland, from 2015 to 2018, in order to ascertain population subtype heterogeneity. Analysis was conducted via real-time PCR amplification and gp60 gene sequencing, which successfully determined the subtype designation of 149 of the 163 (91.4%) tested isolates. Overall, …

Probiotics And Antimicrobial Effect Of Lactiplantibacillus Plantarum, Saccharomyces Cerevisiae, And Bifidobacterium Longum Against Common Foodborne Pathogens In Poultry, Joy Igbafe, Agnes Kilonzo-Nthenge, Samuel N. Nahashon, Abdullah Ibn Mafiz, Maureen Nzomo

Agricultural and Environmental Sciences Faculty Research

The probiotic potential and antimicrobial activity of Lactiplantibacillus plantarum, Saccharomyces cerevisiae, and Bifidobacterium longum were investigated against Escherichia coli O157:H7, Salmonella typhimurium and Listeria monocytogenes. Selected strains were subjected to different acid levels (pH 2.5–6.0) and bile concentrations (1.0–3.0%). Strains were also evaluated for their antimicrobial activity by agar spot test. The potential probiotic strains tolerated pH 3.5 and above without statistically significant growth reduction. However, at pH 2.5, a significant (p < 0.05) growth reduction occurred after 1 h for L. plantarum (4.32 log CFU/mL) and B. longum (5.71 log CFU/mL). S. cerevisiae maintained steady cell counts for the entire treatment period without a statistically significant (p > 0.05) reduction (0.39 log CFU/mL). The results indicate at 3% bile concertation, 1.86 log CFU/mL reduction was observed for L. plantarum, while S. cerevisiae, and B. longum growth …
