Linkages Among Fluorescent Dissolved Organic Matter, Dissolved Amino Acids And Lignin-Derived Phenols In River-Influenced Ocean Margins, Youhei Yamashita, Cédric G. Fichot, Yuan Shen, Rudolf Jaffé, Ronald Benner

Faculty Publications

Excitation emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor analysis (PARAFAC) is commonly used to investigate the dynamics of dissolved organic matter (DOM). However, a lack of direct comparisons with known biomolecules makes it difficult to substantiate the molecular composition of specific fluorescent components. Here, coincident surface-water measurements of EEMs, dissolved lignin, and total dissolved amino acids (TDAA) acquired in the northern Gulf of Mexico were used to investigate the relationships between specific fluorescent components and DOM biomolecules. Two terrestrial humic-like components identified by EEM-PARAFAC using samples obtained from river to offshore waters were strongly linearly correlated with dissolved …

Assessing Student Perceptions Of Indigenous Science Co-Educators, Interest In Stem, And Identity As A Scientist: A Pilot Study, Sarah Alkholy, Fidji Gendron, Tanya Dahms, Maria Pontes Ferreira

Nutrition and Food Science Faculty Research Publications

Minorities are underrepresented in the science, technology, engineering, and mathematics (STEM) workforce, post-secondary STEM education, and show high academic attrition rates. Academic performance and retention improve when culturally relevant support is provided. The interface of Western science and Indigenous science provides an opportunity for bridging this divide. We hypothesized that there would be regional (U.S.A. vs. Canada) differences amongst post-secondary students regarding these variables: perceptions of traditional Elders as STEM co-educators; interest in STEM; and self-identity as a scientist. We conducted a short-term longitudinal pilot study of an interdisciplinary, multi-institutional, and cross-cultural STEM course in the spring of 2013. This …

Screening And Molecular Analysis Of Single Circulating Tumor Cells Using Micromagnet Array, Yu-Yen Huang, Peng Chen, Chun-Hsien Wu, Kazunori Hoshino, Konstantin Sokolov, Nancy Lane, Huaying Liu, Michael Huebschman, Eugene Frenkel, John X.J Zhang

Dartmouth Scholarship

Immunomagnetic assay has been developed to detect rare circulating tumor cells (CTCs), which shows clinical significance in cancer diagnosis and prognosis. The generation and fine-tuning of the magnetic field play essential roles in such assay toward effective single-cell-based analyses of target cells. However, the current assay has a limited range of field gradient, potentially leading to aggregation of cells and nanoparticles. Consequently, quenching of the fluorescence signal and mechanical damage to the cells may occur, which lower the system sensitivity and specificity. We develop a micromagnet-integrated microfluidic system for enhanced CTC detection. The ferromagnetic micromagnets, after being magnetized, generate localized …

Structural Characterization Of A Newly Identified Component Of Α-Carboxysomes: The Aaa+ Domain Protein Csocbbq, Markus Sutter, Evan W. Roberts, Raul C. Gonzalez, Cassandra Bates, Salma Dawoud, Kimberly Landry, Gordon C. Cannon, Sabine Heinhorst, Cheryl A. Kerfeld

Faculty Publications

Carboxysomes are bacterial microcompartments that enhance carbon fixation by concentrating ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and its substrate CO₂ within a proteinaceous shell. They are found in all cyanobacteria, some purple photoautotrophs and many chemoautotrophic bacteria. Carboxysomes consist of a protein shell that encapsulates several hundred molecules of RuBisCO and contain carbonic anhydrase and other accessory proteins. Genes coding for carboxysome shell components and the encapsulated proteins are typically found together in an operon. The α-carboxysome operon is embedded in a cluster of additional, conserved genes that are presumably related to its function. In many chemoautotrophs, products of the expanded carboxysome …

Life Cycle Environmental Impacts For Anaerobic Treatment Of Domestic Wastewater, Valerie Lauren Wade

Master’s Theses

The electricity requirement for aeration in conventional activated sludge treatment of domestic wastewater contributes to high costs and greenhouse gas emissions. Anaerobic treatment, on the other hand, requires no aeration and produces methane that can be converted to electricity and heat. However, the effluent from anaerobic treatment contains dissolved methane¿a potent greenhouse gas¿that would ultimately be released to the atmosphere. Therefore, there is a need to assess the life cycle environmental and economic impacts of anaerobic and aerobic treatment technologies to understand the long-term sustainability of these wastewater treatment options.

Displaying To Females May Lower Male Foraging Time And Vigilance In A Lekking Bird, Sarah A. Cowles, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Males of many species use courtship behavior to attract mates. However, by doing so males may face the associated costs of increased energetic expenditure, reduced foraging time, and elevated predation risk. We investigated the costs of display in lekking male Sharp-tailed Grouse (Tympanuchus phasianellus). We used lek-wide scan sampling to study how males allocated time among courtship display (‘‘dancing’’), agonism, foraging, and inactivity in relation to female numbers both within and across days. We also addressed the limited attention hypothesis and estimated visual attentiveness by videotaping 13 males and scoring head turns during these different activities. We found that the …

Photoacoustic Imaging For Ovarian Cancer Detection: System Development And Classification Algorithm, Hai Li

Doctoral Dissertations

Ovarian cancer is relatively rare but it has the highest mortality with a five-year survival rate of only 30% comparing with other gynecologic cancers. Most of ovarian cancers are diagnosed at late stages because of no efficacious screening techniques. So there is an urgent need to develop new imaging techniques for early stage ovarian cancer detection. Photoacoustic imaging (PAI) inherently combines the merits of optical imaging and ultrasound imaging. In PAI, photoacoustic waves are generated by illuminating tissue samples with a short laser pulse. Photoacoustic waves are then measured by ultrasound transducers to reconstruct optical absorption at ultrasound resolution, which …

Kinematic Analysis Of Wrist Motion During Simulated Colonoscopy In First-Year Gastroenterology Fellows, Shiva K. Ratuapli, Kevin C. Ruff, Francisco C. Ramirez, Qing Wu, Deepika Mohankumar, Marco Santello, David E. Fleischer

Environmental & Global Health Faculty Research

Gastroenterology trainees acquire skill and proficiency in performing colonoscopies at different rates. The cause for heterogeneous competency among the trainees is unclear. Kinematic analysis of the wrist joint while performing colonoscopy can objectively assess the variation in wrist motion. Our objective was to test the hypothesis that the time spent by the trainees in extreme ranges of wrist motion will decrease as the trainees advance through the fellowship year.

North American River Otter (Lontra Canadensis) Presence And Habitat Analysis In Florida As Compared To Historical Data, Samantha Wilber

USF Tampa Graduate Theses and Dissertations

North American river otters are considered common in the state of Florida, but their populations have not been studied since the 1980’s. Since that time, Florida’s human population has more than doubled, and many natural areas of Florida have been developed. The aim of this study was to determine the presence or absence of river otters at locations in Florida which they historically inhabited. Forty-six sample sites where otters were historically found were obtained from the Florida Museum of Natural History Mammals Master Database (FMNH MMD). These sites were condensed to two focus areas, in and around Alachua and Collier …

Influence Of Water Column Stratification And Nutrient Gradients On The Migratory Behavior Of The Red Tide Dinoflagellate, Karenia Brevis, Matthew Garrett

USF Tampa Graduate Theses and Dissertations

Diel vertical migration (DVM) can offer motile phytoplankton a competitive advantage over other phytoplankton species. DVM has been well documented in the harmful dinoflagellate, Karenia brevis; however, the extent to which changes in nutrient regimes and density stratification modify migration patterns has not been thoroughly investigated. A 2 m experimental column was constructed with sensors and sampling ports at four depths to obtain fluorescence and temperature measurements and discrete water samples. The environmental parameters of the experimental column represented temperature and nutrient conditions found on the West Florida Shelf (WFS), where Karenia blooms frequently occur. Results demonstrated a clear …

School-Based Concussion Management: Implementation Characteristics Of Student Services Personnel, Jeffrey Garofano

USF Tampa Graduate Theses and Dissertations

Concussion is an injury that disproportionately affects children and adolescents and has the potential to negatively impact school performance. Currently, a significant proportion of youth with concussion go unreported due to a lack of effective concussion surveillance procedures. Additionally, many individuals who have daily contact with youth (e.g., parents, teachers) lack training in how to assess or manage a concussion. Schools may be the ideal setting to address both of these problems as they have a high level of access to students and employ personnel (e.g., school psychologists, nurses, social workers, counselors) with experience in assessment and intervention. What is …

At The Intersection Of Human Agency And Technology: Genetically Modified Organisms, James Libengood

USF Tampa Graduate Theses and Dissertations

Since the Neolithic period and the rise of agriculture along Mesopotamia’s “Fertile Crescent,” greater societies have formed thus requiring laws and governance to ensure their continued preservation. The Babylonian Code of Hammurabi is one such example of how agricultural technologies directly created new social and institutional structures in codifying slavery into law, or how mercantile transactions are to be conducted. Similarly, GMOs are the result of modern agricultural technologies that are altering laws and society as a result of their implementation. This transformation informs the central inquiries of my research question: Why are GMOs necessary, and what influences do they …

The Impact Of Co2 Emissions On 'Nuisance' Marine Species, Jm Hall-Spencer, R Allen

School of Biological and Marine Sciences

Anthropogenic CO2 emissions are being taken up from the atmosphere by the oceans, increasing the availability of dissolved inorganic carbon but reducing both the carbonate saturation and pH of seawater. This ocean acidification affects biological processes in a wide range of marine taxa. Here, we assess the likely responses of 'nuisance' species to ocean acidification, meaning those organisms that have undesirable effects from a human perspective. Based on a synthesis of evidence available to date, we predict increased growth and toxicity in harmful algal bloom species, and a significant increase in invasive algae in response to increased CO2 availability. Blooms …

Risk-Taking Behavior And Its Impact On Treatment, Vaccination And Diagnosing, Daniel Maxin

Journal of Mind and Medical Sciences

We present results from two recent mathematical biology studies that address the effect of risk-taking behavior on epidemic models. We show that when risk-taking prevails over riskavoidance, it is possible to show a detrimental and counterintuitive effect from increasing vaccination and treatment rates over certain critical time intervals. In addition, when risk-taking has a cumulative effect within the population, a lower transmission rate from diagnosed infected individuals may prevent the intended effect of vaccination.

Solving The Mind-Body Problem Through Two Distinct Concepts: Internal-Mental Existence And Internal Mental Reality, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

In a previous published paper, we initiated in this journal discussion about new perspectives regarding the organization and functioning of the mind, as a premise for addressing the mind-body problem. In this article, we continue focussing discussion on two distinct but interrelated concepts, internal-mental existence/ entity and internal-mental reality.

These two psycho-physiological subunits of the mind interact each other in the form of an internal-mental interaction, having no sense if one is isolated/ studied separately from the other. In other words, the mind (as a dynamic psycho-physiological construction) has no sense in the absence of this internal mental interaction that …

Consumption of drugs of abuse is a scourge of modern world. Abuse, drug addiction and their consequences are one of the major current problems of European society because of the significant repercussions in individual, family, social and economic level. In this context, toxicological analysis of the drugs of abuse in biological samples is a useful tool for: diagnosis of drug addiction, checking an auto-response, mandatory screening in some treatment programs, identification of a substance in the case of an overdose, determining compliance of the treatment.

The present paper aims to address the needs of healthcare professionals involved in drugs addiction …

Cutaneous Manifestations In Inflammatory Bowel Diseases, Simona Roxana Georgescu, Cristina Iulia Mitran, Madalina Irina Mitran, Monica Costescu, Vasile Benea, Maria Isabela Sarbu, Mircea Tampa

Journal of Mind and Medical Sciences

Inflammatory bowel diseases have a high frequency in Europe. They are chronic disorders that evolve with relapses and remissions. Clinical features include the signs of underlying inflammatory bowel disease and also signs of extraintestinal manifestations. Cutaneous disorders are the most common extraintestinal manifestations associated with inflammatory bowel diseases, which can be dependent on or independent of gastrointestinal disease activity. The main cutaneous disorders are erythema nodosum and pyodermagangrenosum. The pathogenic mechanisms are not fully understood but it seems that related mechanisms are involved in the development of inflammatory bowel diseases and extraintestinal manifestations. Treatment should be aimed at both the …

Current Concepts On Drug Abuse And Dependence, Daniela Luiza Baconi, Anne-Marie Ciobanu, Ana Maria Vlăsceanu, Oana Denisa Cobani, Carolina Negrei, Cristian Bălălău

Journal of Mind and Medical Sciences

Drug addiction is a complex disease characterized by compulsive and uncontrollable desire to seek and consume the drug. In time, drug-related terminology has undergone many changes, arising from the deepening of the mechanisms of action, but also about the need for a greater precision in the definition.

Drug dependence can be assigned not only to pharmacological effects of the drugs of abuse, but also to their interaction with each particular neurological and psychological constitution. The research on the neurobiological mechanisms of addiction processes allows both a better understanding of current pharmacotherapy and the development of new treatment strategies in drug …

The Mind And Sexuality: Introduction To A Psychophysiological Perspective, David L. Rowland, Ion G. Motofei

Journal of Mind and Medical Sciences

Cognition and sexuality are two distinct relational functions that are partially interconnected through our mind. Even though medical sciences have progressed substantially over the past decades, the current understanding of the mind psycho-physiology is yet at an early stage. As an example, the “mind-body problem” draws attention to the fact that fundamental aspects related to the understanding of the mind are still unresolved. Thus, it continues to be unclear how abstract ideas and thoughts (which are immaterial in nature, unfolding in an intangible realm) interface (and in some cases, interfere) with the more concrete brain and body (which are physical …
