Toward Culturally Relevant Emotion Detection Using Physiological Signals, Khadija Zanna

USF Tampa Graduate Theses and Dissertations

Research shows that emotional distress has a statistically significant impact on a student’s grade point average and intent to drop out of college. Because students of different races have varying college experiences, it is important to understand the emotional experiences of different racial groups to better support students’ needs and academic success. In this work, we explore several physiological responses to ten different emotional stimuli captured from 140 students. We employ unsupervised learning via the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm and supervised learning via Random Forests and Support Vector machines to analyze clustering partitions and classification …

Structure Based Inhibitor Discovery Targeting Multiple Β-Lactamases Involved In Antibiotic Resistance, Afroza Akhtar

USF Tampa Graduate Theses and Dissertations

Emergence of antibiotic resistance severely threatens the existing medication and prevention facilities against an over increasing range of infections caused by a wide range of microbes. Specifically, treatment of Gram-negative bacterial infection is getting more problematic due to their resilience against β-lactam antibiotics: the most commonly prescribed antibiotics in clinical settings. Production of β-lactamases is the most prevalent mechanism utilized by various Gram-negative pathogens to become resistant to the β-lactam antibiotics e.g, penicillins, cephalosporins, carbapenems and monobactams. These enzymes mediate their function through hydrolyzing the core β-lactam ring present in all β-lactam antibiotics which causes opening of the ring and …

Accelerated Viral Dynamics In Bat Cell Lines, With Implications For Zoonotic Emergence, Cara E. Brook, Mike Boots, Kartik Chandran, Andrew P. Dobson, Christian Drosten, Andrea L. Graham, Bryan T. Grenfell, Marcel A. Müller, Melinda Ng, Lin-Fa Wang, Anieke Van Leeuwen

KIP Articles

Bats host virulent zoonotic viruses without experiencing disease. A mechanistic understanding of the impact of bats’ virus hosting capacities, including uniquely constitutive immune pathways, on cellular-scale viral dynamics is needed to elucidate zoonotic emergence. We carried out virus infectivity assays on bat cell lines expressing induced and constitutive immune phenotypes, then developed a theoretical model of our in vitro system, which we fit to empirical data. Best fit models recapitulated expected immune phenotypes for representative cell lines, supporting robust antiviral defenses in bat cells that correlated with higher estimates for within-host viral propagation rates. In general, heightened immune responses limit …

Survey Of Histoplasma Capsulatum In Bat Guano And Status Of Histoplasmosis In Slovenia, Central Europe, Janez Mulec, Saša Simčič, Tadeja Kotar, Romina Kofol, Sanja Stopinšek

International Journal of Speleology

There have been increasing reports on the presence of Histoplasma capsulatum in some European countries. The study investigated the presence of Histoplasma in bat guanos, speleologists with records of visiting Histoplasma-endemic regions and patients with histoplasmosis. A commercial ALPHA Histoplasma Antigen enzyme immunoassay was tested as an alternative methodology to detect Histoplasma in environment and compared with polymerase chain reaction (PCR) assays. The presence of Histoplasma antigen in bat guanos was not confirmed by PCR. Among 14 healthy speleologists, two were indicated as having the Histoplasma antigen in urine, but expressed negative PCR-specific results for the Histoplasma antigen. Five …

First-Time Characterization Of Viable But Non-Culturable Proteus Mirabilis: Induction And Resuscitation, Reham Wasfi, G. R. Abdellatif, H. M. Elshishtawy, Hossam M. Ashour

USF St. Petersburg Campus Faculty Publications

Pathogenic bacteria can enter into a viable but non-culturable (VBNC) state under unfavourable conditions. Proteus mirabilis is responsible for dire clinical consequences including septicaemia, urinary tract infections and pneumonia, but is not a species previously known to enter VBNC state. We suggested that stress-induced P. mirabilis can enter a VBNC state in which it retains virulence. P. mirabilis isolates were incubated in extreme osmotic pressure, starvation, low temperature and low pH to induce a VBNC state. Resuscitation was induced by temperature upshift and inoculation in tryptone soy broth with Tween 20 and brain heart infusion broth. Cellular ultrastructure and gene …

Background: Comorbid mental disorders in patients with TB may exacerbate TB treatment outcomes. We systematically reviewed current evidence on the association between mental disorders and TB outcomes.

Methods: We searched eight databases for studies published from 1990 to 2018 that compared TB treatment outcomes among patients with and without mental disorders. We excluded studies that did not systematically assess mental disorders and studies limited to substance use. We extracted study and patient characteristics and effect measures and performed a meta-analysis using random-effects models to calculate summary odds ratios (ORs) with 95% confidence intervals (CIs).

Results: Of 7687 studies identified, 10 …

Human Immunodeficiency Virus: A Literary Review On Gene Editing, Cytotherapy, And Medicinal Marijuana As Therapies For Hiv., Paula Moreno

USF St. Petersburg campus Honors Program Theses (Undergraduate)

Human immunodeficiency virus (HIV) affects about 40 million people world-wide; there is currently no cure for HIV or Acquired Immunodeficiency Syndrome (AIDS). This paper will begin by explaining viruses/retroviruses and HIV infection/progression at the molecular, cellular, and organismal level. Common drug therapy will be mentioned, followed by in-depth discussions on the processes of three different therapies that combat HIV-1 at either the molecular, cellular, or organismal level. Once the virus has been integrated in the genome, antiretroviral therapies (ART) begin. At the molecular level, gene silencing has the power to essentially “shut down” or “cut out” genes from the integrated …

USF St. Petersburg Campus Faculty Publications

The emergence of biofilm-forming, multi-drug-resistant (MDR) Proteus mirabilis infections is a serious threat that necessitates non-antibiotic therapies. Antibiotic susceptibility and biofilm-forming activity of P. mirabilis isolates from urine samples were assessed by disc diffusion and crystal violet assays, respectively. Antimicrobial activities of probiotic Lactobacilli were evaluated by agar diffusion. Antibiofilm and anti-adherence activities were evaluated by crystal violet assays. While most P. mirabilis isolates were antibiotic-resistant to varying degrees, isolate P14 was MDR (resistant to ceftazidime, cefotaxime, amoxicillin-clavulanic acid, imipenem, ciprofloxacin, and amikacin) and formed strong biofilms. Cultures and cell-free supernatants of Lactobacillus casei and Lactobacillus reuteri exhibited antimicrobial and …

Yersinia Outer Membrane Vesicles As Potential Vaccine Candidates In Protecting Against Plague, Andrey A. Byvalov, Ilya V. Konyshev, Vladimir N. Uversky, Svetlana V. Dentovskaya, Andrey P. Anisimov

Molecular Medicine Faculty Publications

Despite the relatively low incidence of plague, its etiological agent, Yersinia pestis, is an exceptional epidemic danger due to the high infectivity and mortality of this infectious disease. Reports on the isolation of drug-resistant Y. pestis strains indicate the advisability of using asymmetric responses, such as phage therapy and vaccine prophylaxis in the fight against this problem. The current relatively effective live plague vaccine is not approved for use in most countries because of its ability to cause heavy local and system reactions and even a generalized infectious process in people with a repressed immune status or metabolic disorders, as …

Iyaniwura, Rebeca C. Falcao, Michael C. Otterstatter, Michael A. Irvine, Naveed Z. Janjua, Daniel Coombs, Caroline Colijn

All publications

Extensive non-pharmaceutical and physical distancing measures are currently the primary interventions against coronavirus disease 2019 (COVID-19) worldwide. It is therefore urgent to estimate the impact such measures are having. We introduce a Bayesian epidemiological model in which a proportion of individuals are willing and able to participate in distancing, with the timing of distancing measures informed by survey data on attitudes to distancing and COVID-19. We fit our model to reported COVID-19 cases in British Columbia (BC), Canada, and five other jurisdictions, using an observation model that accounts for both underestimation and the delay between symptom onset and reporting. We …

Modeling The Role Of Asymptomatics In Infection Spread With Application To Sars-Cov-2, Hana M. Dobrovolny

All publications

SARS-CoV-2 started causing infections in humans in late 2019 and has spread rapidly around the world. While the number of symptomatically infected and severely ill people is high and has overwhelmed the medical systems of many countries, there is mounting evidence that some of the rapid spread of this virus has been driven by asymptomatic infections. In this study, we use a compartmental mathematical model of a viral epidemic that includes asymptomatic infection to examine the role of asymptomatic individuals in the spread of the infection. We apply the model to epidemics in California, Florida, New York, and Texas, finding …

Spleen Participation In Partial Mhc Class Ii Construct Neuroprotection In Stroke, John Brown, Chase Kingsbury, Jea-Young Lee, Arthur A. Vandenbark, Roberto Meza-Romero, Halina Offner, Cesar V. Borlongan

Neurosurgery and Brain Repair Faculty Publications

Pathological progression of stroke in the peripheral and central nervous systems (PNS and CNS) is characterized by multiple converging signalling pathways that exacerbate neuroinflammation-mediated secondary cell death. This creates a need for a novel type of immunotherapy capable of simultaneously lowering the synergistic inflammatory responses in the PNS and CNS, specifically the spleen and brain. Previously, we demonstrated that partial major histocompatibility complex (MHC) class II constructs can be administered subcutaneously to promote histological and behavioural effects that alleviate common symptoms found in a murine model of transient stroke. This MHC class II manipulates T cell cytokine expression in both …
