Faculty, Staff and Students Publications

The development of the mammalian cerebellum is orchestrated by both cell-autonomous programs and inductive environmental influences. Here, we describe the main processes of cerebellar ontogenesis, highlighting the neurogenic strategies used by developing progenitors, the genetic programs involved in cell fate specification, the progressive changes of structural organization, and some of the better-known abnormalities associated with developmental disorders of the cerebellum.

Mycobacterial Contamination Of Bronchoscopes: Challenges And Possible Solutions In Low Resource Settings, Dania Khalid Saeed, Sadia Shakoor, Seema Irfan, Rumina Hasan

Department of Pathology and Laboratory Medicine

The use of bronchoscopes has increased in tuberculosis (TB) diagnostics to circumvent the diagnostic challenges that are associated with low sputum volume and smear-negative TB. In healthcare facilities situated in low income countries that have a high burden of TB, adequate decontamination of bronchoscopes is a challenge and often overlooked to save on time and costs. This amplifies the risk of outbreaks and pseudo-outbreaks due to Mycobacterium tuberculosis and nontuberculosis mycobacteria. In this minireview, we review published literature of contaminated bronchoscopes causing pseudo-outbreaks of M. tuberculosis and nontuberculosis mycobacteria in an effort to determine common sources, and possible mitigation strategies …

Hepatitis C Screening In The Homeless Population Of Philadelphia, Adam Zimilover

CwiC Posters

Hepatitis C is a viral infectious disease that is a major cause of liver disease around the world. By the 1970s, it was recognized that many hepatitis cases were not due to the known hepatitis A or hepatitis B viruses. It was not until 1989 when the virus, then known as non--‐A, non--‐B hepatitis, was identified as a new distinct virus, hepatitis C. The virus has seven major genotypes, with genotype 1 causing about 75% of cases in the United States. By 1990, a screening test for the virus was developed, and within a year, the first treatment for the …

Secondary Analysis Of Morbidity Data From A Rural Haitian Village., Emma Karin Draluck

Electronic Theses and Dissertations Archive

Haiti is the poorest country in the Western Hemisphere with most of the population surviving on $1 per day. Health outcomes among Haitians are poor, with a life expectancy 16 years less than the US. The majority of health research in Haiti has been narrow, focusing on specific issues like tuberculosis, HIV/AIDS, maternal health, and cholera. Unfortunately, this has resulted an incomplete understanding of health in Haiti. This study aims to fill this gap by describing the most common health complaints, how they differ by age, sex, and temporality, and if there are associations between these health issues and environmental …

Language Change And Ideology In Irish Radio Advertising, Joan O'Sullivan

Irish Communication Review

This paper examines language ideological change in the Irish context through a longitudinal analysis of accent choice in a corpus of radio ads from 1977, 1987, 1997 and 2007. The analysis is based on Sussex’s (1989) ad components of Action and Comment. The Action component is generally comprised of contextual dialogic interaction and associated with discourses of ‘everyday informal interaction’ while the Comment component, often associated with the slogan of the ad, tends to be monologic and decontextualised and is associated with discourses of ‘power and authority’ (Lee, 1992). The use of standard British English accent features, particularly in …

Combating Ebola With Repurposed Therapeutics Using The Cando Platform, Gaurav Chopra, Sashank Kaushik, Peter L. Elkin, Ram Samudrala

Department of Chemistry Faculty Publications

Ebola virus disease (EVD) is extremely virulent with an estimated mortality rate of up to 90%. However, the state-of-the-art treatment for EVD is limited to quarantine and supportive care. The 2014 Ebola epidemic in West Africa, the largest in history, is believed to have caused more than 11,000 fatalities. The countries worst affected are also among the poorest in the world. Given the complexities, time, and resources required for a novel drug development, finding efficient drug discovery pathways is going to be crucial in the fight against future outbreaks. We have developed a Computational Analysis of Novel Drug Opportunities (CANDO) …

Severe Mortality Impact Of The 1957 Influenza Pandemic In Chile., Gerardo Chowell, Lone Simonsen, Rodrigo Fuentes, Jose Flores, Mark A Miller, Cécile Viboud

Microbiology, Immunology, and Tropical Medicine Faculty Publications

INTRODUCTION: Epidemiological studies of the 1957 influenza pandemic are scarce, particularly from lower-income settings.

METHODS: We analyzed the spatial-temporal mortality patterns of the 1957 influenza pandemic in Chile, including detailed age-specific mortality data from a large city, and investigated risk factors for severe mortality impact across regions.

RESULTS: Chile exhibited two waves of excess mortality in winter 1957 and 1959 with a cumulative excess mortality rate of 12 per 10 000, and a ~10-fold mortality difference across provinces. High excess mortality rates were associated with high baseline mortality (R(2) =41.8%; P=.02), but not with latitude (P>.7). Excess mortality rates …

Gildner, Tara J. Cepon-Robins, Melissa A. Liebert, Samuel S. Urlacher, Felicia C. Madimenos, J. Josh Snodgross, Lawrence S. Sugiyama

Publications and Research

Background: Soil-transmitted helminth (STH) infection peaks during childhood and varies by sex. The impact of market integration (MI) (increasing production for and consumption from a market-based economy) on these infection patterns, however, is unclear. In this study, STH infection is examined by sex and age among indigenous Shuar inhabiting two regions of Amazonian Ecuador: (1) the modestly market-integrated Upano Valley (UV) and (2) the more traditional Cross-Cutucú (CC) region.

Methods: Kato-Katz fecal smears were examined for parasite presence and infection intensity. Factorial ANOVAs and post hoc simple effects analyses were performed by sex to compare infection intensity between regions and …

Nucleoside-Diphosphate-Kinase Of P. Gingivalis Is Secreted From Epithelial Cells In The Absence Of A Leader Sequence Through A Pannexin-1 Interactome, Kalina Atanasova, Jungnam Lee, Joann Roberts, Kyulim Lee, David M. Ojcius, Özlem Yilmaz

All Dugoni School of Dentistry Faculty Articles

Nucleoside-diphosphate-kinases (NDKs) are leaderless, multifunctional enzymes. The mode(s) of NDK secretion is currently undefined, while extracellular translocation of bacterial NDKs is critical for avoidance of host pathogen clearance by opportunistic pathogens such as Porphyromonas gingivalis. P. gingivalis-NDK during infection inhibits extracellular-ATP (eATP)/P2X7-receptor mediated cell death in gingival epithelial cells (GECs) via eATP hydrolysis. Furthermore, depletion of pannexin-1-hemichannel (PNX1) coupled with P2X7-receptor blocks the infection-induced eATP release in GECs, and P. gingivalis-NDK impacts this pathway. Ultrastructural and confocal microscopy of P. gingivalis-co-cultured GECs or green-fluorescent-protein (GFP)-P. gingivalis-NDK transfected GECs revealed a perinuclear/cytoplasmic localization of NDK. eATP stimulation induced NDK recruitment to …

Influence Of Tick And Mammalian Physiological Temperatures On Borrelia Burgdorferi Biofilms, Shafiq Shaikh, Venkata Arun Timmaraju, Jason Torres, Kayla Socarras, Priyanka A. Theophilus, Eva Sapi

Biology and Environmental Science Faculty Publications

The spirochaete bacterium Borrelia burgdorferi sensu lato is the aetiologic agent of Lyme disease. Borrelia is transmitted to mammals through tick bite and is adapted to survive at tick and mammalian physiological temperatures. We have previously shown that B. burgdorferi can exist in different morphological forms, including the antibiotic-resistant biofilm form, in vitro and in vivo. B. burgdorferi forms aggregates in ticks as well as in humans, indicating potential of biofilm formation at both 23 and 37 °C. However, the role of various environmental factors that influence Borrelia biofilm formation remains unknown. In this study, we investigated the effect …

The Effects Of Phytohormones And Isoprenoids In Dihydroartemisinin-Induced Dormancy In The Erythrocytic Stages Of Plasmodium Falciparum, Marvin Duvalsaint Duvalsaint

USF Tampa Graduate Theses and Dissertations

Our ability to control malaria has been challenged by increasing antimalarial resistance. Plasmodium falciparum undergoes dormancy in the blood stages which is hypothesized to be a means by which they are able to survive under drug pressure. This helps select for resistant parasites which grow following removal of drug. The mechanisms behind dormancy and the subsequent recrudescence are not fully understood but translating knowledge from related organisms which undergo a similar phenomenon might shed some light. Higher plants utilize dormancy during the early development stages to survive under unfavorable conditions, increasing fitness of the seedling and ensuring viability when this …

Mitochondrial Heteroplasmy Contributes To The Dynamic Atovaquone Resistance Response In Plasmodium Falciparum, Sasha Victoria Siegel

USF Tampa Graduate Theses and Dissertations

Of the considerable challenges researchers face in the control and elimination of malaria, the development of antimalarial drug resistance in parasite populations remains a significant hurdle to progress worldwide. Atovaquone is used in combination with proguanil (Malarone) as an antimalarial treatment in uncomplicated malaria, but is rendered ineffective by the rapid development of atovaquone resistance during treatment. Previous studies have established that de novo mutant parasites confer resistance to atovaquone with a substitution in amino acid 268 in the cytochrome b gene encoded by the parasite mitochondrial genome, yet much is still unknown about how this resistance develops, and whether …

Hiv Glycoprotein Gp120 Impairs Fast Axonal Transport By Activating Tak1 Signaling Pathways, Sarah H. Berth, Nichole Mesnard-Hoaglin, Bin Wang, Hajwa Kim, Yuyu Song, Maria Sapar, Gerardo Morfini, Scott T. Brady

Publications and Research

Sensory neuropathies are the most common neurological complication of HIV. Of these, distal sensory polyneuropathy (DSP) is directly caused by HIV infection and characterized by length-dependent axonal degeneration of dorsal root ganglion (DRG) neurons. Mechanisms for axonal degeneration in DSP remain unclear, but recent experiments revealed that the HIV glycoprotein gp120 is internalized and localized within axons of DRG neurons. Based on these findings, we investigated whether intra-axonal gp120 might impair fast axonal transport (FAT), a cellular process critical for appropriate maintenance of the axonal compartment. Significantly, we found that gp120 severely impaired both anterograde and retrograde FAT. Providing a …

Otitis media (OM) is a broad term describing a group of infectious and inflammatory disorders of the middle ear. Despite antibiotic therapy, acute OM can progress to chronic suppurative otitis media (CSOM) characterized by ear drum perforation and purulent discharge. Pseudomonas aeruginosa is the most common pathogen associated with CSOM. Although, macrophages play an important role in innate immune responses but their role in the pathogenesis of P. aeruginosa-induced CSOM is not known. The objective of this study is to examine the interaction of P. aeruginosa with primary macrophages. We observed that P. aeruginosa enters and multiplies inside human …

Current Antibiotics And Future Herbal Extract Methods To Treat Methicillin-Resistant Staphylococcus Aureus (Mrsa): Focusing On Inhibition Of Penicillin-Binding Protein 2a (Pbp2a), Mgayya R. Makullah

Senior Honors Theses

Methicillin-Resistant Staphylococcus aureus (MRSA) has developed resistance towards a number of antibiotics. This resistance creates a challenge when trying to treat MRSA with a number of antibiotics. This is mainly caused by the penicillin-binding proteins 2a (PBP2a). PBP2a have significantly less affinity for beta-lactam antibiotics compared to the other penicillin-binding proteins (PBPs) expressed by non-resistant strains. New treatments involving a combination of antibiotics and herbal extracts are being developed and used to inactivate PBP2a, allowing the previous ineffective antibiotics to be more effective.
