Watershed Sciences Faculty Publications

Human agriculture, wastewater, and use of fossil fuels have saturated ecosystems with nitrogen and phosphorus, threatening biodiversity and human water security at a global scale. Despite efforts to reduce nutrient pollution, carbon and nutrient concentrations have increased or remained high in many regions. Here, we applied a new ecohydrological framework to ~12,000 water samples collected by the U.S. Environmental Protection Agency from streams and lakes across the contiguous U.S. to identify spatial and temporal patterns in nutrient concentrations and leverage (an indicator of flux). For the contiguous U.S. and within ecoregions, we quantified trends for sites sampled repeatedly from 2000 …

Capital Punishment Of Young Adults In Light Of Evolving Standards Of Science And Decency: Why Ohio Should Raise The Minimum Age For Death Penalty Eligibility To Twenty-Five (25), Talia Stewart

Cleveland State Law Review

Up until the Supreme Court’s 2005 ruling in Roper v. Simmons, juveniles could constitutionally be executed for qualifying criminal offenses. The Roper Court raised the minimum age for execution to eighteen, citing both a national consensus against executing minors, as well as recent research (at the time) showing that juveniles are more vulnerable to negative influences and outside pressures. Since Roper, the Supreme Court has remained silent regarding the requisite minimum age for execution and has left the decision up to individual states. While a slim majority of states have now abolished the death penalty in its entirety, …

Integrating Deep Learning With Microfluidics For Biophysical Classification Of Sickle Red Blood Cells Adhered To Laminin, Niksa Praljak, Shamreen Iram, Utku Goreke, Gundeep Singh, Ailis Hill, Umut A. Gurkan, Michael Hinczewski

Faculty Scholarship

Sickle cell disease, a genetic disorder affecting a sizeable global demographic, manifests in sickle red blood cells (sRBCs) with altered shape and biomechanics. sRBCs show heightened adhesive interactions with inflamed endothelium, triggering painful vascular occlusion events. Numerous studies employ microfluidic-assay-based monitoring tools to quantify characteristics of adhered sRBCs from high resolution channel images. The current image analysis workflow relies on detailed morphological characterization and cell counting by a specially trained worker. This is time and labor intensive, and prone to user bias artifacts. Here we establish a morphology based classification scheme to identify two naturally arising sRBC subpopulations—deformable and non-deformable …

Attenuated Negative Feedback In Monocyte-Derived Macrophages From Persons Living With Hiv: A Role For Ikaros, Celeste Faia, Karlie Plaisance-Bonstaff, Cecilia Vittori, Dorota Wyczechowska, Adam Lassak, Mary Meyaski-Schluter, Krzysztof Reiss, Francesca Peruzzi

School of Medicine Faculty Publications

Persons living with HIV (PLWH) are at higher risk of developing secondary illnesses than their uninfected counterparts, suggestive of a dysfunctional immune system in these individuals. Upon exposure to pathogens, monocytes undergo epigenetic remodeling that results in either a trained or a tolerant phenotype, characterized by hyper-responsiveness or hypo-responsiveness to secondary stimuli, respectively. We utilized CD14+ monocytes from virally suppressed PLWH and healthy controls for in vitro analysis following polarization of these cells toward a pro-inflammatory monocyte-derived macrophage (MDM) phenotype. We found that in PLWH-derived MDMs, pro-inflammatory signals (TNFA, IL6, IL1B, miR-155-5p, and IDO1) dominate over negative feedback signals (NCOR2, …

Impact Of Urbanization Trends On Production Of Key Staple Crops, José F. Andrade, Kenneth G. Cassman, Juan I. Rattalino Edreira, Fahmuddin Agus, Abdullahi Bala, Nanyan Deng, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Urbanization has appropriated millions of hectares of cropland, and this trend will persist as cities continue to expand. We estimate the impact of this conversion as the amount of land needed elsewhere to give the same yield potential as determined by differences in climate and soil properties. Robust spatial upscaling techniques, well-validated crop simulation models, and soil, climate, and cropping system databases are employed with a focus on populous countries with high rates of land conversion. We find that converted cropland is 30–40% more productive than new cropland, which means that projection of food production potential must account for expected …

Direct-To-Consumer Genetic Testing, Ellen W. Clayton, Et Al.

Vanderbilt Law School Faculty Publications

Direct-to-consumer genetic testing is marketed as a tool to uncover ancestry and kin. Recent studies of actual and potential users have demonstrated that individuals’ responses to the use of these tests for these purposes are complex, with privacy, disruptive consequences, potential for misuse, and secondary use by law enforcement cited as potential concerns. We conducted six focus groups with a diverse sample of participants (n = 62) who were aware of but had not used direct-to-consumer genetic tests, in an effort to understand more about what people considering these tests think about the potential value, risks, and benefits of such …

Experiences Of African American Students In Pre-Licensure Schools Of Nursing: A Qualitative Descriptive Study, Barbara Jean White

Dissertations

Despite more than 40 years of research and governmental support, African Americans continue to be underrepresented in the nursing profession compared to the population it serves. Though some progress has been made over the past 20 years, the American Nurses Association (ANA), American Association of Colleges of Nursing (AACN), National Black Nurses Association (NBNA) and Institute of Medicine (IOM) continue to identify increasing diversity as a disciplinary priority. Further understanding of the experiences of African American nursing students is needed to inform decisions about recruitment, retention and successful matriculation of these students. This qualitative descriptive study focused on understanding the …

Living With A Giant, Flowering Parasite: Metabolic Differences Between Tetrastigma Loheri Gagnep. (Vitaceae) Shoots Uninfected And Infected With Rafflesia (Rafflesiaceae) And Potential Applications For Propagation, Jeanmaire Molina, Dejan Nikolic, Jashvanth Raaj Jeevarathanam, Rinat Abzalimov, Eun‑Jung Park, Ronniel Pedales, Elmer‑Rico E. Mojica, Danilo Tandang, William Mclaughlin, Kyle Wallick, James Adams, Ari Novy, Susan K. Pell, Richard B. Van Breemen, John M. Pezzuto

Advanced Science Research Center

Main conclusion: Metabolites in Rafflesia-infected and non-infected Tetrastigma were compared which may have applications in Rafflesia propagation. Benzylisoquinoline alkaloids, here reported for the first time in Vitaceae, were abundant in non-infected shoots and may be a form of defense. In Rafflesia-infected shoots, oxylipins, which mediate immune response, were elevated.

Endemic to the forests of Southeast Asia, Rafflesia (Rafflesiaceae) is a genus of holoparasitic plants producing the largest flowers in the world, yet completely dependent on its host, the tropical grape vine, Tetrastigma. Rafflesia species are threatened with extinction, making them an iconic symbol of plant conservation. Thus …

Using Artificial Intelligence To Decipher Epigenetic Code Of Drug Resistance In The Deadliest Human Malaria Parasite, Samira Jahangiri

USF Tampa Graduate Theses and Dissertations

Malaria remains one of the immense global public health challenges, with an estimated ~200 million cases worldwide in 2019 despite the remarkable gains in reducing this deadly disease over the past decade. The recent emergence and spread of artemisinin resistance (ART-R) in Plasmodium falciparum will increasingly impede global efforts to control and eliminate malaria. Previous studies have observed broad transcriptional changes and identified several noncoding genetic variants strongly associated with ART-R. The broad transcriptional variations suggest that the malaria parasite uses sophisticated epigenetic regulation to survive under drug pressure. Therefore, evaluating the regulatory effects of noncoding-variants in malaria parasites is …

Effects Of Exogenous Ketone Therapy On Performance, Cardiorespiration, And Seizure Genesis During Exposure To Hbo2 In The Sprague Dawley Rat, Nicole M. Stavitzski

USF Tampa Graduate Theses and Dissertations

Hyperbaric oxygen (HBO2) is used for clinical HBO2 therapy and in undersea and aerospace medicine. HBO2 is a humanmade extreme environment and protracted exposures can cause several adverse physiological effects on the body. For example, HBO2 increases the partial pressure of oxygen (PO2) in the body leading to redox stress. Redox stress is, in part, a cause of oxygen toxicity that manifests as seizures in its most severe form (central nervous system oxygen toxicity, CNS-OT). This dissertation focuses on strategies to be employed specifically for the warfighter breathing HBO2. Currently, the only way to prevent CNS-OT is to lower the …

Obesity rates are climbing, representing a confounding and contributing factor to many disease states, including cancer. With respect to breast cancer, obesity plays a prominent role in the etiology of this disease, with certain subtypes such as triple-negative breast cancer having a strong correlation between obesity and poor outcomes. Therefore, it is critical to examine the obesity-related alterations to the normal stroma and the tumor microenvironment (TME). Adipocytes and adipose stem cells (ASCs) are major components of breast tissue stroma that have essential functions in both physiological and pathological states, including energy storage and metabolic homeostasis, physical support of breast …

Igg4-Mediated Neurologic Autoimmunities: Understanding The Pathogenicity Of Igg4, Ineffectiveness Of Ivig, And Long-Lasting Benefits Of Anti-B Cell Therapies, Marinos Dalakas

Department of Neurology Faculty Papers

Background and objectives: Describe the unique functions of immunoglobulin G4 (IgG4) in IgG4-neurologic disorders (IgG4-ND) and explain why, in contrast to their IgG1-counterparts, they respond poorly to intravenous immune globulin (IVIg) but effectively to anti-B cell therapies.

Methods: The IgG4 structure and isotype switch, B cells and plasmablasts relevant to IgG4 production, and IgG4-induced disruption of the targeted antigens are reviewed and compared with IgG1-mediated autoimmune ND, where IVIg inhibits IgG1-triggered inflammatory effects.

Results: The main IgG4-ND include muscle-specific kinase myasthenia; nodal/paranodal chronic inflammatory demyelinating polyradiculoneuropathy with antibodies to neurofascin-155, contactin-1/caspr-1, or pan-neurofascins; antileucine-rich, glioma-inactivated-1 and contactin-associated protein-like 2 associated-limbic …

Faculty, Staff and Students Publications

Diarrhea in an immunocompromised patient has a broad infectious differential. Diagnosis is difficult despite advances in diagnostic modalities. We report a case of a 45-year-old Nigerian woman who immigrated to the United States 2 years ago. She presented to the hospital with gastrointestinal bleeding, newly diagnosed HIV, and disseminated Kaposi sarcoma. During hospitalization, the patient had an onset of watery diarrhea and high eosinophilia. Subsequent stool analysis using multi-parallel real-time quantitative polymerase chain reaction for 13 parasites was positive for Cystoisospora belli. The patient was treated with trimethoprim-sulfamethoxazole, but had relapsed disease when her antibiotics were stopped prematurely. After restarting …

Transgenic Maize Hybrid Crop Residues: Nutritive Value And Their Effects On Performance Of Grazing Beef Cows, S. K. Barnhart, J. R. Russell, M. J. Hersom, D. E. Farnham

IGC Proceedings (1977-2023)

Several maize (Zea mays) hybrids, including three transgenic hybrids containing Bacillus thuringiensis (Bt) enzymes (Bt-maize hybrids), were planted in a field study. Mature, midgestation, beef cows (Bos tarus) strip-grazed post-harvest residues as paddocks over 126 days. Body condition-scores and weights were monitored. Forage yield, weathering losses and forage composition were monitored on grazed and ungrazed areas. Forage selection and intake were estimated. Grain yields, dropped grain, initial crop residue concentrations of dry matter (DM), organic matter (OM) and in vitro digestible organic matter (IVDOM) yields were similar among hybrids. Hybrids varied in infestation of maize borers, …

Supplementation Of Temperate Pastures, D. H. Rearte, G. A. Pieroni

IGC Proceedings (1977-2023)

Generally in temperate regions, beef and milk were produced on extensive systems with forage from perennial pasture and natural grassland being the main component of animal diet. Supplementation on pasture was usually applied strategically to supply nutrients to grazing cattle only when forage availability was not enough to satisfy animal’s requirements. At present beef and dairy production systems have become more intensive and even when forage from pasture continue being the main component of the diet higher level of different type of supplement are fed to the animals. Intensive systems are characterized by a higher stocking rate capable of consuming …

Feeding Of Conserved Forage - Implications To Grassland Management And Production, C. W. Holmes, P. N. P. Matthews

IGC Proceedings (1977-2023)

This review will focus on the use of conserved forages in pastoral dairy farm systems; especially on their conservation as an aid to good grazing management during periods of rapid pasture growth, and on their consumption as an aid to good feeding management and grazing management during periods of slow pasture growth. Conservation of pasture, in order to move it from one time to another later time, always involves “costs”, either financial expenditure or physical losses (of dry matter/quality) or both, which must be evaluated in the whole system.

Most of the data is drawn from New Zealand and Australia, …

Protein Sources For Growing Beef Steers Fed With A Diet Based On Corn Silage, M. De León, E. Ustarroz, C. Boetto, J. M. Simondi, M. Bulaschevich

IGC Proceedings (1977-2023)

This study was conducted to determine the effect of different protein sources in growing beef cattle (25 Aberdeen Angus steers) fed with a corn silage based diet on daily live weight gain (DLWG), dry matter intake (DMI) and feed conversion (FC). Five treatments with different supplies of crude, degradable and metabolizable protein (MP) were used. The treatments were formulated with different protein sources to provide different rate and extents of protein degradation, as follow: a negative control (T0) without protein supplements and below animal requirements, urea (T1), soybean meal (T2), whole cotton seed (T3) and a positive control (T4), which …
